as A Direct Fluorometric Activity Assay for Lipid Kinases and Phosphatases [Methods] By feedproxy.google.com Published On :: 2020-04-27T13:30:26-07:00 Lipid kinases and phosphatases play key roles in cell signaling and regulation, and are implicated in many human diseases, and are hence thus attractive targets for drug development. Currently, no direct in vitro activity assay is available for these important enzymes, which hampers mechanistic studies as well as high-throughput screening of small molecule modulators. Here we report a highly sensitive and quantitative assay employing a ratiometric fluorescence sensor that directly and specifically monitors the real-time concentration change of a single lipid species. Due Because of to its modular design, the assay system can be applied to a wide variety of lipid kinases and phosphatases, including Class I phosphoinositide 3-kinase (PI3K) and phosphatase and tensin homolog (PTEN). When applied to PI3K, the assay provided the newdetailed mechanistic information about the product inhibition and substrate acyl acyl-chain selectivity of PI3K and allowed enabled rapid evaluation of its small molecule inhibitors. We also used this assay to quantitatively determine the substrate specificity of PTEN, providing new insight into its physiological functionThe assay also quantitatively determined the substrate specificity of PTEN, thereby providing new insight into its physiological function. In summary, we have developed a fluorescence-based real-time assay for PI3K and PTEN that we anticipate could be adapted to measure the activities of other lipid kinases and phosphatases with high sensitivity and accuracy.

as Catalytic residues, substrate specificity, and role in carbon starvation of the 2-hydroxy FA dioxygenase Mpo1 in yeast [Research Articles] By feedproxy.google.com Published On :: 2020-04-29T08:36:37-07:00 The yeast protein Mpo1 belongs to a protein family that is widely conserved in bacteria, fungi, protozoa, and plants, and is the only protein of this family whose function has so far been elucidated. Mpo1 is an Fe2+-dependent dioxygenase that catalyzes the α-oxidation reaction of 2-hydroxy (2-OH) long-chain FAs produced in the degradation pathway of the long-chain base phytosphingosine. However, several biochemical characteristics of Mpo1, such as its catalytic residues, membrane topology, and substrate specificity, remain unclear. Here, we report that yeast Mpo1 contains two transmembrane domains and that both its N- and C-terminal regions are exposed to the cytosol. Mutational analyses revealed that three histidine residues conserved in the Mpo1 family are especially important for Mpo1 activity, suggesting that they may be responsible for the formation of coordinate bonds with Fe2+. We found that, in addition to activity toward 2-OH long-chain FAs, Mpo1 also exhibits activity toward 2-OH very-long-chain FAs derived from the FA moiety of sphingolipids. These results indicate that Mpo1 is involved in the metabolism of long-chain to very-long-chain 2-OH FAs produced in different pathways. We noted that the growth of mpo1 cells is delayed upon carbon deprivation, suggesting that the Mpo1-mediated conversion of 2-OH FAs to non-hydroxy FAs is important for utilizing 2-OH FAs as a carbon source under carbon starvation. Our findings help to elucidate the as-yet-unknown functions and activities of other Mpo1 family members. Full Article
as Parenteral lipids shape gut bile acid pools and microbiota profiles in the prevention of cholestasis in preterm pigs [Research Articles] By feedproxy.google.com Published On :: 2020-04-29T08:36:37-07:00 Multi-component lipid emulsions, rather than soy-oil emulsions, prevent cholestasis by an unknown mechanism. Here, we quantified liver function, bile acid pools, and gut microbial and metabolite profiles in premature, parenterally fed pigs given a soy-oil lipid emulsion, Intralipid (IL); a multi component lipid emulsion, SMOFlipid (SMOF); a novel emulsion with a modified fatty-acid composition (EXP); or a control enteral diet (ENT) for 22 days. We assayed serum cholestasis markers; measured total bile acid levels in plasma, liver, and gut contents; and analyzed colonic bacterial 16S rRNA gene sequences and metabolomic profiles. Serum cholestasis markers (i.e. bilirubin, bile acids, and g-glutamyl transferase) were highest in IL-fed pigs and normalized in those given SMOF, EXP, or ENT. Gut bile acid pools were lowest in the IL treatment and were increased in the SMOF and EXP treatments and comparable to ENT. Multiple bile acids, especially their conjugated forms, were higher in the colon contents of SMOF and EXP than in IL pigs. Colonic microbial communities of SMOF and EXP pigs had lower relative abundance of several Gram-positive anaerobes, including Clostridrium XIVa, and higher abundance of Enterobacteriaceae than those of IL and ENT pigs. Differences in lipid and microbial-derived compounds were also observed in colon metabolite profiles. These results indicate that multi-component lipid emulsions prevent cholestasis and restore enterohepatic bile flow in association with gut microbial and metabolomic changes. We conclude that sustained bile flow induced by multi-component lipid emulsions likely exerts a dominant effect in reducing bile acid–sensitive, Gram-positive bacteria. Full Article
as Sphingolipids distribution at mitochondria-associated membranes (MAM) upon induction of apoptosis. [Research Articles] By feedproxy.google.com Published On :: 2020-04-29T08:36:37-07:00 The levels and composition of sphingolipids and related metabolites are altered in aging and common disorders such as diabetes and cancers, as well as in neurodegenerative, cardiovascular, and respiratory diseases. Changes in sphingolipids have been implicated as being an essential step in mitochondria-driven cell death. However, little is known about the precise sphingolipid composition and modulation in mitochondria or related organelles. Here, we used LC–MS/MS to analyze the presence of key components of the ceramide metabolic pathway in vivo and in vitro in purified endoplasmic reticulum (ER), mitochondria-associated membranes (MAM), and mitochondria. Specifically, we analyzed the sphingolipids in the three pathways that generate ceramide: sphinganine in the de novo ceramide pathway, sphingomyelin in the breakdown pathway, and sphingosine in the salvage pathway. We observed sphingolipid profiles in mouse liver, mouse brain, and a human glioma cell line (U251). We analyzed the quantitative and qualitative changes of these sphingolipids during staurosporine (STS)-induced apoptosis in U251 cells. Ceramide, especially C16-ceramide, levels increased during early apoptosis possibly through a conversion from mitochondrial sphinganine and sphingomyelin, but sphingosine and lactosyl- and glucosyl-ceramide levels were unaffected. We also found that ceramide generation is enhanced in mitochondria when sphingomyelin levels are decreased in the MAM. This decrease was associated with an increase in acid sphingomyelinase (ASM) activity in MAM. We conclude that meaningful sphingolipid modifications occur in MAM, the mitochondria, and ER during the early phases of apoptosis. Full Article
as Mass spectrometry imaging and LC-MS reveal decreased cerebellar phosphoinositides in Niemann-Pick type C1-null mice [Research Articles] By feedproxy.google.com Published On :: 2020-05-05T13:30:26-07:00 Niemann-Pick disease, type C1 (NPC1) is a lipid storage disorder in which cholesterol and glycosphingolipids accumulate in late endosomal/lysosomal compartments because of mutations in the NPC1 gene. A hallmark of NPC1 is progressive neurodegeneration of the cerebellum as well as visceral organ damage; however, the mechanisms driving this disease pathology are not fully understood. Phosphoinositides are phospholipids that play distinct roles in signal transduction and vesicle trafficking. Here, we utilized consensus spectra analysis of MS imaging datasets and orthogonal LC–MS analyses to evaluate the spatial distribution of phosphoinositides and quantify them in cerebellar tissue from Npc1-null mice. Our results suggest significant depletion of multiple phosphoinositide species, including phosphatidylinositol (PI), phosphatidylinositol monophosphate (PIP), and bisphosphate (PIP2), in the cerebellum of the Npc1-null mice in both whole-tissue lysates and myelin-enriched fractions. Additionally, we observed altered levels of the regulatory enzyme phosphatidylinositol 4-kinase type 2 α (PI4K2A) in Npc1-null mice. In contrast, the levels of related kinases, phosphatases, and transfer proteins were unaltered in the Npc1-null mouse model as observed by Western blot analysis. Our discovery of phosphoinositide lipid biomarkers for NPC1 opens new perspectives on the pathophysiology underlying this fatal neurodegenerative disease. Full Article
as Coronavirus: Why The EU Needs to Unleash The ECB By feedproxy.google.com Published On :: Wed, 18 Mar 2020 13:00:36 +0000 18 March 2020 Pepijn Bergsen Research Fellow, Europe Programme @pbergsen LinkedIn COVID-19 presents the eurozone with an unprecedented economic challenge. So far, the response has been necessary, but not enough. 2020-03-18.jpg EU President of Council Charles Michel chairs the coronavirus meeting with the leaders of EU member countries via teleconference on March 17, 2020. Photo by EU Council / Pool/Anadolu Agency via Getty Images. The measures taken to limit the spread of the coronavirus - in particular social distancing - come with significant economic costs, as the drop both in demand for goods and services and in supply due to workers being at home sick will create a short-term economic shock not seen in modern times.Sectors that are usually less affected by regular economic swings such as transport and tourism are being confronted with an almost total collapse in demand. In the airline sector, companies are warning they might only be able to hold out for a few months more.Building on the calls to provide income support to all citizens and shore up businesses, European leaders should now be giving explicit permission to the European Central Bank (ECB) to provide whatever financial support is needed.Although political leaders have responded to the economic threat, the measures announced across the continent have mainly been to support businesses. The crisis is broader and deeper than the current response.Support for weaker governmentsThe ECB already reacted to COVID-19 by announcing measures to support the banking system, which is important to guarantee the continuity of the European financial system and to ensure financially weaker European governments do not have to confront a failing banking system as well.Although government-subsidised reduced working hours and sick pay are a solution for many businesses and workers, crucially they are not for those working on temporary contracts or the self-employed. They need direct income support.This might come down to instituting something that looks like a universal basic income (UBI), and ensuring money keeps flowing through the economy as much as possible to help avoid a cascade of defaults and significant long-term damage.But while this is likely to be the most effective remedy to limit the medium-term impact on the economy, it is particularly costly. Just as an indication, total compensation of employees was on average around €470bn per month in the eurozone last year.Attempting to target payments using existing welfare payment channels would reduce costs, but is difficult to implement and runs the risk of many households and businesses in need missing out.The increase in spending and lost revenue associated with these support measures dwarf the fiscal response to the 2008-09 financial crisis. The eurozone economy could contract by close to 10% this year and budget deficits are likely be in double digits throughout the bloc.The European Commission has already stated member states are free to spend whatever is necessary to combat the crisis, which is not surprising given the Stability and Growth Pact - which includes the fiscal rules - allows for such eventualities.Several eurozone countries do probably have the fiscal space to deal with this. Countries such as Germany and the Netherlands have run several years of balanced budgets recently and significantly decreased their debt levels. For countries such as Italy, and even France, it is a different story and the combination of much higher spending and a collapse in tax revenue is more likely to lead to questions in the market over the sustainability of their debt levels. In order to avoid this, the Covid-19 response must be financed collectively.The Eurogroup could decide to use the European Stability Mechanism (ESM) to provide states with the funds, while suitably ditching the political conditionality that came with previous bailout. But the ESM currently has €410bn in remaining lending capacity, which is unlikely to be enough and difficult to rapidly increase.So this leaves the ECB to pick up the tab of national governments’ increase in spending, as the only institution with effectively unlimited monetary firepower. But a collective EU response is complicated by the common currency, and particularly by the role of the ECB.The ECB can’t just do whatever it likes and is limited more than other major central banks in its room for manoeuvre. It does have a programme to buy government bonds but this relies on countries agreeing to a rescue programme within the context of the ESM, with all the resulting political difficulties.There are two main ways that the ECB could finance the response to the crisis. First, it could buy up more or all bonds issued by the member states. A first step in this direction would be to scrap the limits on the bonds it can buy. Through self-imposed rules, the ECB can only buy up to a third of every country’s outstanding public debt. There are good reasons for this in normal times, but these are not normal times. With the political blessing of the European Council, the Eurosystem of central banks could then start buying bonds issued by governments to finance whatever expenditure they deem necessary to combat the crisis.Secondly, essentially give governments an overdraft with the ECB or the national central banks. Although a central bank lending directly to governments is outlawed by the European treaties, the COVID-19 crisis means these rules should be temporarily suspended by the European Council.Back in 2012, the then president of the ECB, Mario Draghi, proclaimed the ECB would do whatever it takes, within its mandate, to save the euro, which was widely seen as a crucial step towards solving the eurozone crisis. The time is now right for eurozone political leaders to explicitly tell the ECB that together they can do whatever it takes to save the eurozone economy through direct support for businesses and households.

as Why The Insurgency in Northern Mozambique Has Got Worse By feedproxy.google.com Published On :: Wed, 01 Apr 2020 17:14:28 +0000 1 April 2020 Dr Alex Vines OBE Managing Director, Ethics, Risk & Resilience; Director, Africa Programme Two attacks on towns in northern Mozambique by suspected jihadists point to a rapidly deteriorating security crisis. 2020-04-01-Mozambique Macomia, Cabo Delgado, Northern Mozambique. Photo by EMIDIO JOSINE/AFP via Getty Images. On March 23 to 24, the centre of Mocimboa da Praia in Cabo Delgado province was occupied by up to 40 “jihadists”, who targeted government facilities, including a barracks, and brandished banners of affiliation to the so-called Islamic State.On March 25, suspected jihadists raided the town of Quissanga and destroyed the district police headquarters. They too carried an Islamic State flag. Twenty to 30 members of Mozambique’s security forces were killed in both attacks.Mocimboa da Praia is just south of the Afungi Peninsula, the location of gas projects worth $60- billion. Mocimboa was briefly occupied in late 2017, during attacks claimed by a group known as Ahlu Sunnah Wa-Jama (or al-Sunnah) that marked the start of a brutal low-intensity conflict, with widespread human rights abuses and attacks on civilians.Up to 1,000 people have now been killed and 100,000 displaced. More recently, The Islamic State Central Africa Province (Iscap), affiliated with the Islamic State group, has claimed responsibility for the attacks. Video and photos of these most recent events, along with the testimony of frightened residents and overstretched government officials, suggest a shift of strategy by the insurgents.There seems to have been an effort to avoid harming civilians, to win hearts and minds by redistributing stolen food, medicine and fuel to “loyal” residents, and to direct attacks on the state and its symbols, such as police stations and military barracks. It is difficult from a distance to assess if there was any genuine pleasure over these attacks among local people; while residents in both towns that did not flee seemed to welcome the attackers, this may well have been out of fear that the government is currently unable to guarantee their security.These attacks also indicate that the jihadist-linked insurgents are growing in confidence. They are confronting government security forces with little appetite for fighting. The Mozambican government has been expecting setbacks like those of Mocimboa and Quissanga — its forces are demoralised and many commanders exhausted or corrupted by an emerging war economy. Jihadists are also taking tactical advantage before a reformed and more effective government counterinsurgency effort is introduced in response.President Filipe Nyusi, inaugurated in January for his second term, has made this crisis his prime focus and has become the de-facto minister of defence.Military reform and the role of private military companiesBut there is no quick fix. Most importantly, the Mozambican military and security forces need to be restructured. They were unable to win the Mozambican civil war (1977-1992), even with international support, and have not improved in capacity or conduct since. They now face a complex, multilayered and asymmetrical conflict, mostly drawing upon local and regional grievances and networks but increasingly also attracting some limited encouragement and advice from further afield.Nyusi will need to build-up trusted relationships in the military in the way he has successfully done with parts of the intelligence community. The Mozambican government has already reached out to international expertise — though not necessarily the right kind. The founder of the Blackwater private military company, Erik Prince, supplied two helicopters and support crew for the Mozambican military in mid-2019, before being replaced by some 170 Russian privateers linked to the Wagner Group.The Wagner contingent arrived in September 2019 at Nacala airport with trucks, drones and a Mi-17 helicopter gunship, then deployed into the combat zone of northern Cabo Delgado. Setbacks, including at least two dead Russians, forced a tactical fallback to Nacala, though a new effort is reported to have been underway since late February 2020.The Mozambican government is also considering a number of proposals from other private military companies. Maputo needs to consider these carefully; Israeli or Gulf State involvement in any form might exasperate rather than alleviate this crisis.The Tanzanian connectionBut market-led security and military providers will not end this insurgency. Nor will the engagement of states such as the United States, France, the United Kingdom or Angola, all of which have made their own offers of support. What would significantly make a difference is much closer to home: serious Tanzanian engagement.This insurgency is concentrated in districts bordering Tanzania and there is clear-cut intelligence of connections into Tanzania and beyond. Swahili is also a lingua franca for the jihadists, connecting them up the East African coast, and into eastern Congo and elsewhere.It is puzzling, given the deep shared history between Tanzania and Mozambique, that the bilateral relationship is as patchy as it is today: during the liberation struggle (1965-1974) against the Portuguese, Mozambique’s ruling party Frelimo maintained rear bases in Tanzania, and Nyusi was educated there.Conspiracy theories circulate that Tanzania has encouraged the Cabo Delgado insurgency to weaken its neighbour, or at least displace radicalised individuals from Tanzanian soil into Mozambique.President John Magafuli of Tanzania did not attend the January inauguration of Nyusi. It has become urgent that Magafuli (who is also the current chair of the regional body, the Southern African Development Community) and Nyusi meet face-to-face to map out improved intelligence sharing and a joint strategy to respond to an emerging regional threat.Southern Africa is locking down because of Covid-19, which will distract the government’s ability to focus fully on this crisis and create a perfect moment for the infant insurgency in Cabo Delgado to grow. More military setbacks should be expected in coming months.But the Mozambican government can still contain and prevail if it seriously reforms its military, builds strong alliances with its regional neighbours (especially Tanzania), chooses its private security contractors and international partnerships wisely, and backs military efforts with better intelligence and developmental interventions that offer alternative pathways to potential recruits.But despite Maputo’s hope that significant progress will be made over the coming year, and the setting up of a presidential task force to evaluate progress and intelligence, it is likely that Mozambique and its partners will need to prepare themselves for a drawn-out struggle.This article originally appeared in the Mail & Guardian Full Article
as COVID 19: Assessing Vulnerabilities and Impacts on Iraq By feedproxy.google.com Published On :: Tue, 07 Apr 2020 14:33:01 +0000 7 April 2020 Dr Renad Mansour Senior Research Fellow, Middle East and North Africa Programme; Project Director, Iraq Initiative @renadmansour Dr Mac Skelton Director, Institute of Regional and International Studies (IRIS), American University of Iraq, Sulaimani; Visiting Fellow, Middle East Centre, London School of Economics Dr Abdulameer Mohsin Hussein President of the Iraq Medical Association Following 17 years of conflict and fragile state-society relations, the war-torn country is particularly vulnerable to the pandemic. 2020-04-07-Iraq-COVID-spray Disinfecting shops in Baghdad's Bayaa neighbourhood as a preventive measure against the spread of COVID-19. Photo by AHMAD AL-RUBAYE/AFP via Getty Images. Iraq is a country already in turmoil, suffering fallout from the major military escalation between the US and Iran, mass protests calling for an end to the post-2003 political system, and a violent government crackdown killing more than 600 and wounding almost 30,000 - all presided over by a fragmented political elite unable to agree upon a new prime minister following Adil abd al-Mehdi’s resignation back in November.COVID-19 introduces yet another threat to the fragile political order, as the virus exposes Iraq’s ineffective public health system dismantled through decades of conflict, corruption and poor governance.Iraqi doctors are making every effort to prepare for the worst-case scenario, but they do so with huge structural challenges. The Ministry of Health lacks enough ICU beds, human resources, ventilators, and personal protective equipment (PPE). Bogged down in bureaucracy, the ministry is struggling to process procurements of equipment and medications, and some doctors have made purchases themselves.But individual efforts can only go so far as many Iraqi doctors are concerned the official numbers of confirmed COVID-19 cases do not reflect the complexity of the situation on the ground.The ministry relies predominately upon patients self-presenting at designated public hospitals and has only just begun community-based testing in areas of suspected clusters. Reliance on self-presentation requires a level of trust between citizens and state institutions, which is at a historic low. This gap in trust – 17 years in the making – puts Iraq’s COVID-19 response particularly at risk.Iraq’s myriad vulnerabilitiesCertain social and political factors leave Iraq uniquely exposed to the coronavirus. The country’s vulnerability is tied directly to its social, religious and economic interconnections with Iran, an epicenter of the pandemic.Exchanges between Iran and Iraq are concentrated in two regions, with strong cross-border links between Iraqi and Iranian Kurds in the north-east, and Iraqi and Iranian Shia pilgrims in the south. Cross-border circulation of religious pilgrims is particularly concerning, as they can result in mass ritual gatherings.The high number of confirmed cases in the southern and northern peripheries of the country puts a spotlight on Iraq's failure in managing healthcare. The post-2003 government has failed to either rebuild a robust centralized healthcare system, or to pave the way for a federalized model.Caught in an ambiguous middle between a centralized and federalized model, coordination across provinces and hospitals during the coronavirus crisis has neither reflected strong management from Baghdad nor robust ownership at the governorate level.This problem is part of a wider challenge of managing centre-periphery relations and federalism, which since 2003 has not worked effectively. Baghdad has provided all 18 provinces with instructions on testing and treatment, but only a handful have enough resources to put them into practice. Advanced testing capacity is limited to the five provinces with WHO-approved centers, with the remaining 13 sending swabs to Baghdad.But the greatest challenge to Iraq’s COVID-19 response is the dramatic deterioration of state-society relations. Studies reveal a profound societal distrust of Iraq’s public healthcare institutions, due to corruption and militarization of medical institutions. Numerous videos have recently circulated of families refusing to turn over sick members - particularly women - to medical teams visiting households with confirmed or suspected cases.As medical anthropologist Omar Dewachi notes, the ‘moral economy of quarantine’ in Iraq is heavily shaped by a history of war and its impact on the relationship between people and the state. Although local and international media often interpret this reluctance to undergo quarantine as a matter of social or tribal norms, distrusting the state leads many families to refuse quarantine because they believe it resembles a form of arrest.The management of coronavirus relies upon an overt convergence between medical institutions and security forces as the federal police collaborate with the Ministry of Health to impose curfews and enforce quarantine. This means that, troublingly, the same security establishment which violently cracked down on protesters and civil society activists is now the teeth behind Iraq’s COVID-19 response.Without trust between society and the political class, civil society organizations and protest movements have directed their organizational structure towards awareness-raising across Iraq. Key religious authorities such as Grand Ayatollah Sistani have called for compliance to the curfew and mobilized charitable institutions.However, such efforts will not be enough to make up for the lack of governance at the level of the state. In the short-term, Iraq’s medical professionals and institutions are in dire need of technical and financial support. In the long-term, COVID-19 is a lesson that Iraq’s once robust public healthcare system needs serious investment and reform.COVID-19 may prove to be another catalyst challenging the ‘muddle through’ logic of the Iraqi political elite. International actors have largely been complicit in this logic, directing aid and technical support towards security forces and political allies in the interest of short-term stability, and neglecting institutions which Iraqis rely on for health, education, and well-being.The response to the crisis requires cooperation and buy-in of a population neglected by 17 years of failed governance. This is a seminal event that may push the country to the brink, exposing and stirring underlying tensions in state-society relations.This analysis was produced as part of the Iraq Initiative.

Part two examines Ukraine’s appeal to the International Criminal Court (ICC) to seek individual criminal responsibility of the alleged perpetrators of the gravest crimes in occupied Crimea and eastern Ukraine. 2020-04-23-Ukraine-Anniversary-Conflict Marking the Day of The National Flag of Ukraine, a day before celebrations of the anniversary of state independence. Photo by ANATOLII STEPANOV/AFP via Getty Images. The recognition by Ukraine of the jurisdiction of the International Criminal Court (ICC) to consider grave crimes allegedly perpetrated in its territory has led to the ICC Prosecutor’s preliminary examination identifying a wave of alleged war crimes and crimes against humanity.There are claims of persecution, forced conscription, deportation, sham trials, enforced disappearances, and property seizure - in Crimea. As well as killings, torture, inhuman treatment, sexual violence, and indiscriminate shelling - in Donbas. The court now needs to decide whether to open a full investigation which could lead to charges against specific individuals, as in the trial currently taking place in the Netherlands over MH-17.However, the ICC does remain a court of last resort as Ukraine retains the principal power to prosecute grave violations perpetrated in its eastern regions and Crimea, with the court only stepping in if Ukraine (or another court with jurisdiction) is either unwilling or unable to do so.As the evidence mounts up, Ukrainian investigators, prosecutors and judges are becoming more open to cooperation with foreign experts, law firms, human rights NGOs and younger domestic professionals - a significant proportion of whom are women.Transformation shows determinationThis is an unusual shift, given the rigid hierarchical nature of post-Soviet institutions, with elderly males in most of the top positions. The transformation shows the determination to see perpetrators of crimes in Crimea and Donbas tried by the ICC, with joint professional development trainings and joint communications about the alleged crimes.Ukraine has also been strengthening its institutions. The Prosecutor’s Office of the Autonomous Republic of Crimea has been improving quality control of its war crime proceedings, and has taken a strong pro-ICC stance. The Office of the Prosecutor General established a special department to monitor the armed conflict proceedings, and two specialised war crime units have been formed in Donbas.Although too early to assess progress - given recent prosecution reform and that much-needed legislation on international crimes is still pending – these are promising signs of Ukraine’s intent to take a specialised approach to armed conflict violations. And Ukrainian civil society organisations are also playing a more important role, documenting alleged crimes and sending evidence to the ICC.Any intervention by the ICC in Ukraine also has a considerable impact on the wider dynamics of addressing international crimes, further extending the court’s reach beyond a focus on Africa which has attracted widespread criticism since it began in 2002.The ICC has already opened investigations in Georgia, Bangladesh/Myanmar, and Afghanistan, with preliminary examinations in Colombia, Venezuela, Iraq/UK, Palestine, and The Philippines. But the Ukrainian case would further develop the European subtleties of the court’s jurisprudence.Although the ICC is currently investigating the 2008 Russia-Georgia war, the active phase of that armed conflict lasted for just five days whereas Russia’s military involvement in Ukraine has been ongoing for the six years. The temporal difference in no way diminishes the suffering of victims and the necessity for the proper investigation, prosecution and compensation in the Georgian context.And yet, going by even the preliminary findings of the ICC prosecutor, the spectrum of war crimes and crimes against humanity allegedly perpetrated in Ukraine is much wider. Some incidents, such as the illegal construction of the Crimean Bridge, is an amalgam of the violations against property, cultural heritage and the environment. Cumulatively, the Ukrainian and Georgian cases would substantially contribute to the development of the court’s emerging European lenses.The Russia-Ukraine armed conflict is also the first instance of armed hostilities of such magnitude and duration in Europe since World War II and the Yugoslav Wars. The ICC’s readiness to take on such geopolitically challenging cases which leave itself open to attack will be tested.But by examining new contexts - including Ukraine - the ICC would develop a more layered reading of the nature and scope of the crimes it works on. For example, alleged indoctrination and use of children by armed groups in eastern Ukraine is likely to differ from the known practices of abducting and recruiting child soldiers in Africa.Investigating evidence of Russia’s persecution of pro-Ukrainian activists - forcing them out of Crimea - coupled with the creation of favourable conditions for Russian citizens to relocate to Crimea could lead to proving the existence of a policy of mass colonisation of the peninsula - adding new layers to the court’s jurisprudence on population displacement. And previously under-prosecuted crimes may come to the fore, such as attacks on cultural property or causing the destruction of the environment.Although the ICC proceedings on Ukraine – along with those being held by the International Court of Justice (ICJ) - are unlikely to bring immediate results, Ukraine has developed an international adjudication strategy based on the available viable options and what can be practically delivered.The simple act of a reputed international court outlining Russia’s alleged violations in Crimea and Donbas and naming those individually responsible would be an impactful achievement in itself, regardless of whether Russia pays any attention or compensation.And any international judgments or those of domestic courts such as the Dutch MH-17 proceedings and Russia’s response - predicted to be non-compliance - is an important argument for continuing sanctions against Russia over its conduct in Ukraine.The mutually reinforcing effect of both the Crimea and Donbas proceedings within Ukraine and at international courts should not be underestimated. These investigations into war crimes, terrorism and human rights issues are deeply relevant - not only for the conflict itself, but also for the development of international law.Part One of this series assesses Ukraine’s efforts to hold Russia accountable as a state at the International Court of Justice (ICJ).

as COVID-19 Crisis – Business as Usual for Gaza? By feedproxy.google.com Published On :: Wed, 06 May 2020 14:48:14 +0000 6 May 2020 Mohammed Abdalfatah Asfari Foundation Academy Fellow @mhalabi258 LinkedIn The COVID-19 pandemic has brought unprecedented challenges, economic collapse and strict lockdowns in many parts of the world. For the people of Gaza, this reality is nothing new. 2020-05-06-covid-19-gaza.jpg Palestinians light fireworks above the rubble during the Muslim holy month of Ramadan amid concerns about the spread of the coronavirus disease (COVID-19), in Gaza City , 30 April 2020. Photo by Majdi Fathi/NurPhoto via Getty Images. In August 2012, when the UN released its report Gaza in 2020: A liveable place?, they could not have imagined what the world would look like in 2020: cities under lockdown, restrictions on movement, border closures, widespread unemployment, economic collapse, fear and anxiety and, above all, uncertainty about what the future holds.For Gaza’s population of 2 million people this reality is nothing new. The conditions that the rest of the world are currently experiencing as a result of the COVID-19 pandemic is similar to the tight blockade Gaza has been living under ever since Hamas took over in 2007. Israel has imposed severe restrictions on the movement of people and goods, youth unemployment has reached 60 per cent, and over 80 per cent of Gaza’s population are now dependent on international aid.The people of Gaza are having to face the COVID-19 crisis already at a disadvantage, with poor infrastructure, limited resources and a shortage of the most basic services, such as water and power supply. It also has a fragile health system, with hospitals lacking essential medical supplies and equipment, as well as the capacity to deal with the outbreak as there are only 84 ICU beds and ventilators available. Meanwhile, intra-Palestinian divisions have persisted and were evident in the initial reaction to the pandemic. When President Mahmoud Abbas announced a state of emergency, it took two days for the Hamas-led government in Gaza to follow suit and shut down schools and universities. They later made a separate emergency appeal to address the crisis and prepare for a COVID-19 response in Gaza. This lack of coordination is typical of the way the Palestinian Authority and Hamas approach crisis situations.After the initial uncoordinated response, Hamas, as the de-facto ruler of Gaza, has asserted its ability to control Gaza’s borders by putting in place quarantine measures for everyone who enters the strip, whether through the Erez checkpoint with Israel or the Rafah border with Egypt. They have also assigned 21 hospitals, hotels, and schools as compulsory quarantine centres for all arrivals from abroad, who have to stay in quarantine for 21 days. In comparison, there are 20 quarantine centres in the West Bank. These strict measures have prevented the spread of the virus in the community and confined it to the quarantine centres, with only 20 confirmed cases of COVID-19 as of 6 May. Gaza’s de-facto authorities have also been able to monitor markets and prices to ensure the availability of essential goods.Faced with a major crisis, Al-Qassam Brigades – the armed wing of Hamas – have tried to play the role of a national army by participating in efforts to fight the pandemic. They have relatively good logistical capacity and have contributed to the construction of two quarantine facilities with a total capacity of 1,000 units to prepare for more arrivals into Gaza. At the local level, municipalities have been disinfecting public spaces and facilities in addition to disseminating information about the virus and related preventative and protective measures. Other precautionary measures put in place include closing the weekly open markets, and restricting social gatherings like weddings and funerals.Despite COVID-19, it’s business as usual when it comes to international dealings with Gaza. The key parties in the conflict – Israel, Hamas and the Palestinian Authority – along with the main external actors – Egypt, the United Nations and Qatar – have continued to stick to their policies aimed at keeping the security situation under control and preventing further escalation. Although Israel has allowed entry of pharmaceutical supplies and medical equipment into Gaza during the pandemic, it has kept its restrictions on the movement of goods and people in place, while keeping a close eye on the development of the COVID-19 outbreak in Gaza – a major outbreak here would be a nightmare scenario for Israel.Meanwhile, Qatar has continued to address the humanitarian and economic needs of Gaza in an attempt to ease the pressure and prevent further escalation. It has pledged $150 million over the next six months to help families in Gaza from poorer backgrounds. Gaza has also been discussed by the Middle East Quartet, as Nickolay Mladenov, the UN special coordinator for the Middle East Peace Process, expressed his concern about the risk of a disease outbreak in Gaza during a call with the members of the Quartet.Amid the pandemic, threats are still being exchanged between Israel and Hamas. The Israeli defence minister, Naftali Bennett, requested that in return for providing humanitarian aid to Gaza, Hamas agrees to return the remains of two Israeli soldiers killed in the 2014 war. While openly rejecting Bennett's statement, the leader of Hamas in Gaza, Yahya Sinwar, has offered to move forward with a prisoner swap deal if Israel agrees to release elderly prisoners and detainees in addition to detained women and children. Though dealing with its own COVID-19 outbreak, Egypt has started to mediate between the two parties in an attempt to stabilize the situation and reach a prisoner swap deal.In the wake of this pandemic, lessons should be learned and policies should be examined, by all parties. Firstly, Israel should re-evaluate its security measures towards Gaza by easing restrictions on movement and trade which would have a positive impact on living conditions for Gaza’s population. The current measures have proven to be unsustainable and have contributed to the endless cycle of violence. Secondly, the intra-Palestinian division should end, to save Palestinians from contradictory policies and insufficient capacity on both sides. In fact, all previous attempts have failed to end this self-destructive division and this is due to the absence of political will on both sides. Elections seem to be the only viable path towards unity. Finally, efforts by the international community should go beyond stabilizing the security situation and ongoing crisis inside Gaza, where disruption of normal life is the norm.While the world has reacted to this pandemic with a whole host of new policies and emergency measures, it has remained business as usual when dealing with Gaza. Should COVID-19 spread in Gaza, its people – who have already paid the price of a continuous blockade and intra-Palestinian division for 13 years – will pay a heavy price yet again. However, this time it is not a crisis that they alone will have to face. Full Article
as Oxidative stress-mediated regulation of proteasome complexes [Other] By feedproxy.google.com Published On :: 2011-01-31T16:50:35-08:00 Oxidative stress has been implicated in aging and many human diseases, notably neurodegenerative disorders and various cancers. The reactive oxygen species that are generated by aerobic metabolism and environmental stressors can chemically modify proteins and alter their biological functions. Cells possess protein repair pathways to rescue oxidized proteins and restore their functions. If these repair processes fail, oxidized proteins may become cytotoxic. Cell homeostasis and viability are therefore dependent on the removal of oxidatively damaged proteins. Numerous studies have demonstrated that the proteasome plays a pivotal role in the selective recognition and degradation of oxidized proteins. Despite extensive research, oxidative stress-triggered regulation of proteasome complexes remains poorly defined. Better understanding of molecular mechanisms underlying proteasome function in response to oxidative stress will provide a basis for developing new strategies aimed at improving cell viability and recovery as well as attenuating oxidation-induced cytotoxicity associated with aging and disease. Here we highlight recent advances in the understanding of proteasome structure and function during oxidative stress and describe how cells cope with oxidative stress through proteasome-dependent degradation pathways.

as Bayesian Proteoform Modeling Improves Protein Quantification of Global Proteomic Measurements [Technology] By feedproxy.google.com Published On :: 2014-08-16T16:05:43-07:00 As the capability of mass spectrometry-based proteomics has matured, tens of thousands of peptides can be measured simultaneously, which has the benefit of offering a systems view of protein expression. However, a major challenge is that with an increase in throughput, protein quantification estimation from the native measured peptides has become a computational task. A limitation to existing computationally-driven protein quantification methods is that most ignore protein variation, such as alternate splicing of the RNA transcript and post-translational modifications or other possible proteoforms, which will affect a significant fraction of the proteome. The consequence of this assumption is that statistical inference at the protein level, and consequently downstream analyses, such as network and pathway modeling, have only limited power for biomarker discovery. Here, we describe a Bayesian model (BP-Quant) that uses statistically derived peptides signatures to identify peptides that are outside the dominant pattern, or the existence of multiple over-expressed patterns to improve relative protein abundance estimates. It is a research-driven approach that utilizes the objectives of the experiment, defined in the context of a standard statistical hypothesis, to identify a set of peptides exhibiting similar statistical behavior relating to a protein. This approach infers that changes in relative protein abundance can be used as a surrogate for changes in function, without necessarily taking into account the effect of differential post-translational modifications, processing, or splicing in altering protein function. We verify the approach using a dilution study from mouse plasma samples and demonstrate that BP-Quant achieves similar accuracy as the current state-of-the-art methods at proteoform identification with significantly better specificity. BP-Quant is available as a MatLab ® and R packages at https://github.com/PNNL-Comp-Mass-Spec/BP-Quant. Full Article
as Quantitative profiling of protein tyrosine kinases in human cancer cell lines by multiplexed parallel reaction monitoring assays [Technology] By feedproxy.google.com Published On :: 2015-09-25T14:31:13-07:00 Protein tyrosine kinases (PTKs) play key roles in cellular signal transduction, cell cycle regulation, cell division, and cell differentiation. Dysregulation of PTK-activated pathways, often by receptor overexpression, gene amplification, or genetic mutation, is a causal factor underlying numerous cancers. In this study, we have developed a parallel reaction monitoring (PRM)-based assay for quantitative profiling of 83 PTKs. The assay detects 308 proteotypic peptides from 54 receptor tyrosine kinases and 29 nonreceptor tyrosine kinases in a single run. Quantitative comparisons were based on the labeled reference peptide method. We implemented the assay in four cell models: 1) a comparison of proliferating versus epidermal growth factor (EGF)-stimulated A431 cells, 2) a comparison of SW480Null (mutant APC) and SW480APC (APC restored) colon tumor cell lines, and 3) a comparison of 10 colorectal cancer cell lines with different genomic abnormalities, and 4) lung cancer cell lines with either susceptibility (11-18) or acquired resistance (11-18R) to the epidermal growth factor receptor tyrosine kinase inhibitor erlotinib. We observed distinct PTK expression changes that were induced by stimuli, genomic features or drug resistance, which were consistent with previous reports. However, most of the measured expression differences were novel observations. For example, acquired resistance to erlotinib in the 11-18 cell model was associated not only with previously reported upregulation of MET, but also with upregulation of FLK2 and downregulation of LYN and PTK7. Immunoblot analyses and shotgun proteomics data were highly consistent with PRM data. Multiplexed PRM assays provide a targeted, systems-level profiling approach to evaluate cancer-related proteotypes and adaptations. Data are available through Proteome eXchange Accession PXD002706.

as Selection of features with consistent profiles improves relative protein quantification in mass spectrometry experiments [Research] By feedproxy.google.com Published On :: 2020-03-31T13:35:14-07:00 In bottom-up mass spectrometry-based proteomics, relative protein quantification is often achieved with data-dependent acquisition (DDA), data-independent acquisition (DIA), or selected reaction monitoring (SRM). These workflows quantify proteins by summarizing the abundances of all the spectral features of the protein (e.g., precursor ions, transitions or fragments) in a single value per protein per run. When abundances of some features are inconsistent with the overall protein profile (for technological reasons such as interferences, or for biological reasons such as post-translational modifications), the protein-level summaries and the downstream conclusions are undermined. We propose a statistical approach that automatically detects spectral features with such inconsistent patterns. The detected features can be separately investigated, and if necessary removed from the dataset. We evaluated the proposed approach on a series of benchmark controlled mixtures and biological investigations with DDA, DIA and SRM data acquisitions. The results demonstrated that it can facilitate and complement manual curation of the data. Moreover, it can improve the estimation accuracy, sensitivity and specificity of detecting differentially abundant proteins, and reproducibility of conclusions across different data processing tools. The approach is implemented as an option in the open-source R-based software MSstats. Full Article
as Immediate adaptation analysis implicates BCL6 as an EGFR-TKI combination therapy target in NSCLC [Research] By feedproxy.google.com Published On :: 2020-03-31T09:35:18-07:00 Drug resistance is a major obstacle to curative cancer therapies, and increased understanding of the molecular events contributing to resistance would enable better prediction of therapy response, as well as contribute to new targets for combination therapy. Here we have analyzed the early molecular response to epidermal growth factor receptor (EGFR) inhibition using RNA sequencing data covering 13 486 genes and mass spectrometry data covering 10 138 proteins. This analysis revealed a massive response to EGFR inhibition already within the first 24 hours, including significant regulation of hundreds of genes known to control downstream signaling, such as transcription factors, kinases, phosphatases and ubiquitin E3-ligases. Importantly, this response included upregulation of key genes in multiple oncogenic signaling pathways that promote proliferation and survival, such as ERBB3, FGFR2, JAK3 and BCL6, indicating an early adaptive response to EGFR inhibition. Using a library of more than 500 approved and experimental compounds in a combination therapy screen, we could show that several kinase inhibitors with targets including JAK3 and FGFR2 increased the response to EGFR inhibitors. Further, we investigated the functional impact of BCL6 upregulation in response to EGFR inhibition using siRNA-based silencing of BCL6. Proteomics profiling revealed that BCL6 inhibited transcription of multiple target genes including p53, resulting in reduced apoptosis which implicates BCL6 upregulation as a new EGFR inhibitor treatment escape mechanism. Finally, we demonstrate that combined treatment targeting both EGFR and BCL6 act synergistically in killing lung cancer cells. In conclusion, or data indicates that multiple different adaptive mechanisms may act in concert to blunt the cellular impact of EGFR inhibition, and we suggest BCL6 as a potential target for EGFR inhibitor-based combination therapy.

as Investigation of inter- and intra-tumoral heterogeneity of glioblastoma using TOF-SIMS [Research] By feedproxy.google.com Published On :: 2020-04-06T19:35:13-07:00 Glioblastoma (GBM) is one of the most aggressive human cancers with a median survival of less than two years. A distinguishing pathological feature of GBM is a high degree of inter- and intratumoral heterogeneity. Intertumoral heterogeneity of GBM has been extensively investigated on genomic, methylomic, transcriptomic, proteomic and metabolomics levels, however only a few studies describe intratumoral heterogeneity due to the lack of methods allowing to analyze GBM samples with high spatial resolution. Here, we applied TOF-SIMS (Time-of-flight secondary ion mass spectrometry) for the analysis of single cells and clinical samples such as paraffin and frozen tumor sections obtained from 57 patients. We developed a technique that allows us to simultaneously detect the distribution of proteins and metabolites in glioma tissue with 800 nm spatial resolution. Our results demonstrate that according to TOF-SIMS data glioma samples can be subdivided into clinically relevant groups and distinguished from the normal brain tissue. In addition, TOF-SIMS was able to elucidate differences between morphologically distinct regions of GBM within the same tumor. By staining GBM sections with gold-conjugated antibodies against Caveolin-1 we could visualize border between zones of necrotic and cellular tumor and subdivide glioma samples into groups characterized by different survival of the patients. Finally, we demonstrated that GBM contains cells that are characterized by high levels of Caveolin-1 protein and cholesterol. This population may partly represent a glioma stem cells. Collectively, our results show that the technique described here allows to analyze glioma tissues with a spatial resolution beyond reach of most of other omics approaches and the obtained data may be used to predict clinical behavior of the tumor.

as Characterization of signaling pathways associated with pancreatic {beta}-cell adaptive flexibility in compensation of obesity-linked diabetes in db/db mice [Research] By feedproxy.google.com Published On :: 2020-04-07T14:34:38-07:00 The onset of obesity-linked type 2 diabetes (T2D) is marked by an eventual failure in pancreatic β-cell function and mass that is no longer able to compensate for the inherent insulin resistance and increased metabolic load intrinsic to obesity. However, in a commonly used model of T2D, the db/db mouse, β-cells have an inbuilt adaptive flexibility enabling them to effectively adjust insulin production rates relative to the metabolic demand. Pancreatic β-cells from these animals have markedly reduced intracellular insulin stores, yet high rates of (pro)insulin secretion, together with a substantial increase in proinsulin biosynthesis highlighted by expanded rough endoplasmic reticulum and Golgi apparatus. However, when the metabolic overload and/or hyperglycemia is normalized, β-cells from db/db mice quickly restore their insulin stores and normalize secretory function. This demonstrates the β-cell’s adaptive flexibility and indicates that therapeutic approaches applied to encourage β-cell rest are capable of restoring endogenous β-cell function. However, mechanisms that regulate β-cell adaptive flexibility are essentially unknown. To gain deeper mechanistic insight into the molecular events underlying β-cell adaptive flexibility in db/db β-cells, we conducted a combined proteomic and post-translational modification specific proteomic (PTMomics) approach on islets from db/db mice and wild-type controls (WT) with or without prior exposure to normal glucose levels. We identified differential modifications of proteins involved in redox homeostasis, protein refolding, K48-linked deubiquitination, mRNA/protein export, focal adhesion, ERK1/2 signaling, and renin-angiotensin-aldosterone signaling, as well as sialyltransferase activity, associated with β-cell adaptive flexibility. These proteins are all related to proinsulin biosynthesis and processing, maturation of insulin secretory granules, and vesicular trafficking—core pathways involved in the adaptation of insulin production to meet metabolic demand. Collectively, this study outlines a novel and comprehensive global PTMome signaling map that highlights important molecular mechanisms related to the adaptive flexibility of β-cell function, providing improved insight into disease pathogenesis of T2D.

as Modulation of natural HLA-B*27:05 ligandome by ankylosing spondylitis-associated endoplasmic reticulum aminopeptidase 2 (ERAP2) [Research] By feedproxy.google.com Published On :: 2020-04-07T08:35:14-07:00 The human leucocyte antigen (HLA)-B*27:05 allele and the endoplasmic reticulum-resident aminopeptidases are strongly associated with ankylosing spondylitis (AS), a chronic inflammatory spondyloarthropathy. This study examined the effect of endoplasmic reticulum aminopeptidase 2 (ERAP2) in the generation of the natural HLA-B*27:05 ligandome in live cells. Complexes of HLA-B*27:05-bound peptide pools were isolated from human ERAP2-edited cell clones and the peptides were identified using high throughput mass spectrometry analyses. The relative abundance of thousand ligands was established by quantitative tandem mass spectrometry and bioinformatics analysis. The residue frequencies at different peptide position, identified in presence or absence of ERAP2, determined structural features of ligands and their interactions with specific pockets of antigen binding site of HLA-B*27:05 molecule. Sequence alignment of ligands identified with species of bacteria associated with HLA-B*27-dependent reactive arthritis was performed. In the absence of ERAP2, peptides with N-terminal basic residues, and minority canonical P2 residues are enriched in the natural ligandome. Further, alterations of residue frequencies and hydrophobicity profile at P3, P7, and P positions were detected. In addition, several ERAP2-dependent cellular peptides were highly similar to protein sequences of arthritogenic bacteria, including one human HLA-B*27:05 ligand fully conserved in a protein from Campylobacter jejuni. These findings highlight the pathogenic role of this aminopeptidase in the triggering of AS autoimmune disease. Full Article
as Characterization of Prenylated C-terminal Peptides Using a Thiopropyl-based Capture Technique and LC-MS/MS [Research] By feedproxy.google.com Published On :: 2020-04-13T10:35:29-07:00 Post-translational modifications play a critical and diverse role in regulating cellular activities. Despite their fundamentally important role in cellular function, there has been no report to date of an effective generalized approach to the targeting, extraction and characterization of the critical c-terminal regions of natively prenylated proteins. Various chemical modification and metabolic labelling strategies in cell culture have been reported. However, their applicability is limited to cell culture systems and does not allow for analysis of tissue samples. The chemical characteristics (hydrophobicity, low abundance, highly basic charge) of many of the c-terminal regions of prenylated proteins have impaired the use of standard proteomic workflows. In this context, we sought a direct approach to the problem in order to examine these proteins in tissue without the use of labelling. Here we demonstrate that prenylated proteins can be captured on chromatographic resins functionalized with mixed disulfide functions. Protease treatment of resin-bound proteins using chymotryptic digestion revealed peptides from many known prenylated proteins. Exposure of the protease-treated resin to reducing agents and hydro organic mixtures released c-terminal peptides with intact prenyl groups along with other enzymatic modifications expected in this protein family. Database and search parameters were selected to allow for c-terminal modifications unique to these molecules such as CAAX box processing and c-terminal methylation. In summary, we present a direct approach to enrich and obtain information at a molecular level of detail about prenylation of proteins from tissue and cell extracts using high performance LCMS without the need for metabolic labeling and derivatization.

as Seminal Plasma Proteome as an Indicator of Sperm Dysfunction and Low Sperm Motility [Research] By feedproxy.google.com Published On :: 2020-04-20T08:36:49-07:00 Molecular mechanisms underlying sperm motility have not been fully explained, particularly in chickens. The objective was to identify seminal plasma proteins associated with chicken sperm motility by comparing the seminal plasma proteomic profile of roosters with low sperm motility (LSM, n = 4) and high sperm motility (HSM, n = 4). Using a label-free MS-based method, a total of 522 seminal plasma proteins were identified, including 386 (~74%) previously reported and 136 novel ones. A total of 70 differentially abundant proteins were defined, including 48 more-abundant, 15 less-abundant, and seven proteins unique to the LSM group (specific proteins). Key secretory proteins like less-abundant ADGRG2 and more-abundant SPINK2 in the LSM suggested that the corresponding secretory tissues played a crucial role in maintaining sperm motility. Majority (80%) of the more-abundant and five specific proteins were annotated to the cytoplasmic domain which might be a result of higher plasma membrane damage and acrosome dysfunction in LSM. Additionally, more-abundant mitochondrial proteins were detected in LSM seminal plasma associated with lower spermatozoa mitochondrial membrane potential (m) and ATP concentrations. Further studies showed that the spermatozoa might be suffering from oxidative stress, as the amount of spermatozoa reactive oxygen species (ROS) were largely enhanced, seminal malondialdehyde (MDA) concentrations were increased, and the seminal plasma total antioxidant capacity (T-AOC) were decreased. Our study provides an additional catalog of chicken seminal plasma proteome and supports the idea that seminal plasma could be as an indicator of spermatozoa physiology. More-abundant of acrosome, mitochondria and sperm cytoskeleton proteins in the seminal plasma could be a marker of sperm dysfunction and loss of motility. The degeneration of spermatozoa caused the reduced seminal T-AOC and enhanced oxidative stress might be potential determinants of low sperm motility. These results could extend our understanding of sperm motility and sperm physiology regulation. Full Article
as HIGD2A is required for assembly of the COX3 module of human mitochondrial complex IV [Research] By feedproxy.google.com Published On :: 2020-04-21T08:36:14-07:00 Assembly factors play a critical role in the biogenesis of mitochondrial respiratory chain complexes I-IV where they assist in the membrane insertion of subunits, attachment of co-factors, and stabilization of assembly intermediates. The major fraction of complexes I, III and IV are present together in large molecular structures known as respiratory chain supercomplexes. A number of assembly factors have been proposed as required for supercomplex assembly, including the hypoxia inducible gene 1 domain family member HIGD2A. Using gene-edited human cell lines and extensive steady state, translation and affinity enrichment proteomics techniques we show that loss of HIGD2A leads to defects in the de novo biogenesis of mtDNA-encoded COX3, subsequent accumulation of complex IV intermediates and turnover of COX3 partner proteins. Deletion of HIGD2A also leads to defective complex IV activity. The impact of HIGD2A loss on complex IV was not altered by growth under hypoxic conditions, consistent with its role being in basal complex IV assembly. While in the absence of HIGD2A we show that mitochondria do contain an altered supercomplex assembly, we demonstrate it to harbor a crippled complex IV lacking COX3. Our results redefine HIGD2A as a classical assembly factor required for building the COX3 module of complex IV. Full Article
as Flow-induced reorganization of laminin-integrin networks within the endothelial basement membrane uncovered by proteomics [Research] By feedproxy.google.com Published On :: 2020-04-24T09:36:17-07:00 The vessel wall is continuously exposed to hemodynamic forces generated by blood flow. Endothelial mechanosensors perceive and translate mechanical signals via cellular signaling pathways into biological processes that control endothelial development, phenotype and function. To assess the hemodynamic effects on the endothelium on a system-wide level, we applied a quantitative mass spectrometry approach combined with cell surface chemical footprinting. SILAC-labeled endothelial cells were subjected to flow-induced shear stress for 0, 24 or 48 hours, followed by chemical labeling of surface proteins using a non-membrane permeable biotin label, and analysis of the whole proteome and the cell surface proteome by LC-MS/MS analysis. These studies revealed that of the >5000 quantified proteins 104 were altered, which were highly enriched for extracellular matrix proteins and proteins involved in cell-matrix adhesion. Cell surface proteomics indicated that LAMA4 was proteolytically processed upon flow-exposure, which corresponded to the decreased LAMA4 mass observed on immunoblot. Immunofluorescence microscopy studies highlighted that the endothelial basement membrane was drastically remodeled upon flow exposure. We observed a network-like pattern of LAMA4 and LAMA5, which corresponded to the localization of laminin-adhesion molecules ITGA6 and ITGB4. Furthermore, the adaptation to flow-exposure did not affect the inflammatory response to tumor necrosis factor α, indicating that inflammation and flow trigger fundamentally distinct endothelial signaling pathways with limited reciprocity and synergy. Taken together, this study uncovers the blood flow-induced remodeling of the basement membrane and stresses the importance of the subendothelial basement membrane in vascular homeostasis.

as A cross-linking mass spectrometry approach defines protein interactions in yeast mitochondria [Research] By feedproxy.google.com Published On :: 2020-04-24T09:36:17-07:00 Protein cross-linking and the analysis of cross-linked peptides by mass spectrometry is currently receiving much attention. Not only is this approach applied to isolated complexes to provide information about spatial arrangements of proteins but it is also increasingly applied to entire cells and their organelles. As in quantitative proteomics, the application of isotopic labelling further makes it possible to monitor quantitative changes in the protein-protein interactions between different states of a system. Here, we cross-linked mitochondria from Saccharomyces cerevisiae grown on either glycerol- or glucose-containing medium to monitor protein-protein interactions under non-fermentative and fermentative conditions. We investigated qualitatively the protein-protein interactions of the 400 most abundant proteins applying stringent data-filtering criteria, i.e. a minimum of two cross-linked peptide spectrum matches and a cut-off in the spectrum scoring of the used search engine. The cross-linker BS3 proved to be equally suited for connecting proteins in all compartments of mitochondria when compared with its water-insoluble but membrane-permeable derivative DSS. We also applied quantitative cross-linking to mitochondria of both the growth conditions using stable-isotope labelled BS3. Significant differences of cross-linked proteins under glycerol and glucose conditions were detected, however, mainly due to the different copy numbers of these proteins in mitochondria under both the conditions. Results obtained from the glycerol condition indicate that the internal NADH:ubiquinone oxidoreductase Ndi1 is part of an electron transport chain supercomplex. We have also detected several hitherto uncharacterized proteins and identified their interaction partners. Among those, Min8 was found to be associated with cytochrome c oxidase. BN-PAGE analyses of min8 mitochondria suggest that Min8 promotes the incorporation of Cox12 into cytochrome c oxidase. Full Article
as Peptide-based interaction proteomics [Review] By feedproxy.google.com Published On :: 2020-04-28T12:34:32-07:00 Protein-protein interactions are often mediated by short linear motifs (SLiMs) that are located in intrinsically disordered regions (IDRs) of proteins. Interactions mediated by SLiMs are notoriously difficult to study, and many functionally relevant interactions likely remain to be uncovered. Recently, pull-downs with synthetic peptides in combination with quantitative mass spectrometry emerged as a powerful screening approach to study protein-protein interactions mediated by SLiMs. Specifically, arrays of synthetic peptides immobilized on cellulose membranes provide a scalable means to identify the interaction partners of many peptides in parallel. In this minireview we briefly highlight the relevance of SLiMs for protein-protein interactions, outline existing screening technologies, discuss unique advantages of peptide-based interaction screens and provide practical suggestions for setting up such peptide-based screens.

as The DNA sensor cGAS is decorated by acetylation and phosphorylation modifications in the context of immune signaling [Research] By feedproxy.google.com Published On :: 2020-04-28T18:38:31-07:00 The cyclic GMP-AMP synthase (cGAS) protein is a pattern-recognition receptor of the mammalian innate immune system that is recognized as a main cytosolic sensor of pathogenic or damaged DNA. cGAS DNA binding initiates catalytic production of the second messenger, cyclic GMP-AMP, which activates the STING-TBK1-IRF3 signaling axis to induce cytokine expression. Post-translational modification (PTM) has started to be recognized as a critical component of cGAS regulation, yet the extent of these modifications remains unclear. Here, we report the identification and functional analysis of cGAS phosphorylations and acetylations in several cell types under basal and immune-stimulated conditions. cGAS was enriched by immunoaffinity purification from human primary fibroblasts prior to and after infection with herpes simplex virus type 1 (HSV-1), as well as from immune-stimulated STING-HEK293T cells. Six phosphorylations and eight acetylations were detected, of which eight PTMs were not previously documented. PTMs were validated by parallel reaction monitoring (PRM) mass spectrometry in fibroblasts, HEK293T cells, and THP-1 macrophage-like cells. Primary sequence and structural analysis of cGAS highlighted a subset of PTM sites with elevated surface accessibility and high evolutionary sequence conservation. To assess the functional relevance of each PTM, we generated a series of single-point cGAS mutations. Stable cell lines were constructed to express cGAS with amino acid substitutions that prevented phosphorylation (Ser-to-Ala) and acetylation (Lys-to-Arg) or that mimicked the modification state (Ser-to-Asp and Lys-to-Gln). cGAS-dependent apoptotic and immune signaling activities were then assessed for each mutation. Our results show that acetyl-mimic mutations at Lys384 and Lys414 inhibit the ability of cGAS to induce apoptosis. In contrast, the Lys198 acetyl-mimic mutation increased cGAS-dependent interferon signaling when compared to the unmodified charge-mimic. Moreover, targeted PRM quantification showed that Lys198 acetylation is decreased upon infections with two herpesviruses—HSV-1 and human cytomegalovirus (HCMV), highlighting this residue as a regulatory point during virus infection.

as Proteomics of Campylobacter jejuni growth in deoxycholate reveals Cj0025c as a cystine transport protein required for wild-type human infection phenotypes [Research] By feedproxy.google.com Published On :: 2020-05-06T13:56:38-07:00 Campylobacter jejuni is a major cause of food-borne gastroenteritis. Proteomics by label-based two-dimensional liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) identified proteins associated with growth in 0.1% sodium deoxycholate (DOC, a component of gut bile salts), and system-wide validation was performed by data-independent acquisition (DIA-SWATH-MS). LC-MS/MS quantified 1326 proteins (~82% of the predicted C. jejuni proteome), of which 1104 were validated in additional biological replicates by DIA-SWATH-MS. DOC resulted in a profound proteome shift with 512 proteins showing significantly altered abundance. Induced proteins were associated with flagellar motility and antibiotic resistance; and these correlated with increased DOC motility and resistance to polymyxin B and ciprofloxacin. DOC also increased human Caco-2 cell adherence and invasion. Abundances of proteins involved in nutrient transport were altered by DOC and aligned with intracellular changes to their respective carbon sources. DOC increased intracellular levels of sulfur-containing amino acids (cysteine and methionine) and the dipeptide cystine (Cys-Cys), which also correlated with reduced resistance to oxidative stress. A DOC induced transport protein was Cj0025c, which has sequence similarity to bacterial Cys-Cys transporters. Deletion of cj0025c (cj0025c) resulted in proteome changes consistent with sulfur starvation, as well as attenuated invasion, reduced motility, atypical morphology, increased antimicrobial susceptibility and poor biofilm formation. Targeted metabolomics showed cj0025c was capable of utilizing known C. jejuni amino and organic acid substrates commensurate with wild-type. Medium Cys-Cys levels however, were maintained in cj0025c relative to wild-type. A toxic Cys-Cys mimic (selenocystine) inhibited wild-type growth, but not cj0025c. Provision of an alternate sulfur source (2 mM thiosulfate) restored cj0025c motility. Our data confirm that Cj0025c is a Cys-Cys transporter that we have named TcyP consistent with the nomenclature of homologous proteins in other species. Full Article

as It's a man's world: carnal spectatorship and dissonant masculinities in Islamic State videos By feedproxy.google.com Published On :: Thu, 07 May 2020 08:41:04 +0000 7 May 2020 , Volume 96, Number 3 Manni Crone Read Online Islamic State videos have often been associated with savage violence and beheadings. An in-depth scrutiny however reveals another striking feature: that female bodies are absent, blurred or mute. Examining a few Islamic State videos in depth, the article suggests that the invisibility of women in tandem with the ostentatious visibility of male bodies enable gendered and embodied spectators to indulge in homoerotic as well as heterosexual imaginaries. In contrast to studies on visual security and online radicalization which assert that images affect an audience, this article focuses on the interaction between video and audience and argues that spectators are not only rational and emotional but embodied and gendered as well. Islamic State videos do not only attract western foreign fighters through religious–ideological rhetoric or emotional impact but also through gendered forms of pleasure and desire that enable carnal imagination and identification. The article probes the analytical purchase of carnal aesthetics and spectatorship. Full Article
as Soundscapes of war: the audio-visual performance of war by Shi'a militias in Iraq and Syria By feedproxy.google.com Published On :: Thu, 07 May 2020 09:16:54 +0000 7 May 2020 , Volume 96, Number 3 Helle Malmvig Read online This article sets out to bring sound and music to the field of visual studies in International Relations. It argues that IR largely has approached the visual field as if it was without sound; neglecting how audial landscapes frame and direct our interpretation of moving imagery. Sound and music contribute to making imagery intelligible to us, we ‘hear the pictures’ often without noticing. The audial can for instance articulate a visual absence, or blast visual signs, bring out certain emotional stages or subjects’ inner life. Audial frames steer us in distinct directions, they can mute the cries of the wounded in war, or amplify the sounds of joy of soldiers shooting in the air. To bring the audial and the visual analytically and empirically together, the article therefore proposes four key analytical themes: 1) the audial–visual frame, 2) point of view/point of audition, 3) modes of audio-visual synchronization and 4) aesthetics moods. These are applied to a study of ‘war music videos’ in Iraq and Syria made and circulated by Shi'a militias currently fighting there. Such war music videos, it is suggested, are not just artefacts of popular culture, but have become integral parts of how warfare is practiced today, and one that is shared by soldiers in the US and Europe. War music videos are performing war, just as they shape how war is known by spectators and participants alike. Full Article
as Zelenskyy Finds That There Are No Easy Solutions in Donbas By feedproxy.google.com Published On :: Wed, 23 Oct 2019 14:46:36 +0000 23 October 2019 Duncan Allan Associate Fellow, Russia and Eurasia Programme Leo Litra Senior Research Fellow, New Europe Center The president has attempted to use the so-called Steinmeier Formula to find a compromise on holding elections in the east of Ukraine. But he has run into a stark reality: Moscow and Kyiv’s interests remain irreconcilable. 2019-10-23-Ukraine.jpg A banner reading 'No capitulation!' is unfurled above the entrance to the city hall in Kyiv as part of protests against implementation of the so-called Steinmeier Formula. Photo: Getty Images. In 2016, the then-German foreign minister, Frank-Walter Steinmeier, suggested a way around the impasse in east Ukraine.He proposed that elections in the areas held by Russian-backed insurgents – the ‘Donetsk People’s Republic’ (DNR) and the ‘Luhansk People’s Republic’ (LNR) – could be held under Ukrainian legislation, with Kyiv adopting a temporary law on ‘special status’, the main disagreement between Russia and Ukraine in the Minsk Agreements. This law would become permanent once the Organization for Security and Cooperation in Europe (OSCE) had declared that elections correspond with OSCE standards.The reaction in Ukraine was strongly negative. The so-called Steinmeier Formula contradicted Kyiv’s position that elections in the occupied Donbas should only go ahead in a secure environment – requiring the prior withdrawal of Russian forces and the return of the eastern border to Ukraine’s control. It also did not address the differing views of ‘special status’; Russia demands a much greater devolution of constitutional powers to the DNR and LNR regimes than Ukraine will grant.But on 1 October, Volodymyr Zelenskyy, the new Ukrainian president, announced that he was signing up to the Steinmeier Formula. He also announced a conditional withdrawal of Ukrainian forces from two frontline areas in the east.Quick reversalDuring the 2019 presidential election campaign, Zelenskyy repeatedly promised that, if elected, he would re-energize efforts to end the war. This appealed to many Ukrainians, who understandably want the conflict over, although Zelenskyy’s eventual electoral victory was largely won on domestic issues.But his initiative quickly ran into two problems.First, following a major prisoner swap in September, Russian President Vladimir Putin appeared to judge that Zelenskyy was in a hurry to deliver his election promises and was acting without consulting France and Germany. Russia had earlier demanded that Ukraine formally agree to elections in the Donbas as the precondition for a summit of the ‘Normandy’ powers (the diplomatic format comprising leaders of Ukraine, Russia, Germany and France, which has not met since 2016).Moreover, the US, which is not part of the ‘Normandy’ group, has seemed disengaged because of domestic controversies. Concluding that Zelenskyy was vulnerable, the Kremlin welcomed his announcement about the Steinmeier Formula but declined to assent to a summit, hoping to extract further concessions.Second, Zelenskyy’s action triggered protests in Kyiv and other Ukrainian cities. Critics feared that he intended to make unilateral concessions over ‘special status’. Though he tried to assure Ukrainians that ‘there won't be any elections there if the [Russian] troops are still there’, concerns were fuelled by what many saw as his lack of openness about what the Steinmeier Formula really meant. Ukrainian public opinion wants an end to the war, but apparently not at any price.Zelenskyy duly rowed back. During a marathon 14-hour press conference on 10 October, he emphasized that he would not surrender Ukraine’s vital interests. He also acknowledged that he had been insufficiently open with the Ukrainian public. For the time being at least, he seems to have been given pause.A situation resistant to compromiseInstead, Zelenskyy may now attempt to ‘freeze’ the conflict by ending active operations. This is not Ukraine’s favoured outcome but could be the most realistic one in current conditions. Russia still calculates that time is on its side. It believes that Western support for Ukraine is lukewarm and that Kyiv will eventually have to give it what it wants. Russia clearly felt no pressure to respond positively to Zelenskyy’s overture, which it probably read as a weakness to be exploited. For these reasons, Zelenskyy now appears less optimistic that rapid progress to end the war is possible. A new summit of the ‘Normandy’ powers may happen but looks unlikely in the near future. This may act as an incentive for further bilateral negotiations between Ukraine and Russia, such as those which delivered the prisoner swap. However, a diplomatic process managed by Zelenskyy and Putin alone risks reducing Ukraine’s leverage. Finally, the main obstacles to implementation of the Minsk Agreements – radically different views of elections in, and ‘special status’ for, the DNR and LNR – remain. The Kremlin’s versions of both would gravely limit Ukraine’s sovereignty; Kyiv’s would facilitate the re-establishment of its control over the east. It is hard to see how this gap can be bridged.Tellingly, the Steinmeier Formula offers no answer to this conundrum. Some conflicts, it seems, are resistant to diplomatic compromises that aim to satisfy everyone equally. Full Article

as Political Will Was Not Enough for Justice Reform in Moldova By feedproxy.google.com Published On :: Tue, 26 Nov 2019 15:51:37 +0000 27 November 2019 Cristina Gherasimov Former Academy Associate, Russia and Eurasia Programme @cgherasimov The pro-reform Sandu government had the will to dismantle oligarchic power structures, but was taken down by limited political experience. 2019-11-26-Sandu.jpg Maia Sandu in Germany in July. Photo: Getty Images. The lack of political will to carry out rule of law reforms is frequently the reason why reforms are not fully implemented. The case of Moldova proves that in societies where strong vested interests still persist, political savviness is equally as important as political will.Old and new political power brokers in Moldova struck a fragile pact in June to oust Vladimir Plahotniuc. Plahotniuc had built a network of corruption and patronage with the help of the Democratic Party, which he treated as a personal vehicle and which allowed him and a small economic elite circle to enrich themselves off of government institutions and state-owned enterprises, to the detriment of Moldovan citizens and the health of their political process.Maia Sandu, co-leader of the pro-reform ACUM electoral bloc, then formed a technocratic government with a remit to implement Moldova’s lagging reform agenda. Though made up of ministers with the integrity and political will to implement difficult transformational reforms, its biggest weakness was its coalition partner – the pro-Russian Socialists’ Party and its informal leader, Igor Dodon, the president of Moldova.Now the Socialists – threatened by how key reforms to the justice system would impact their interests – have joined forces with Plahotniuc’s former allies, the Democratic Party, to oust ACUM, exploiting the party’s lack of political savviness. Reform interruptedIt was always clear the coalition would be short-lived. President Dodon and the co-ruling Socialists joined to buy themselves time, with the hope that they could restrict the most far-reaching reforms and tie the hands of ACUM ministers. In less than five months, however, the Sandu government initiated key reforms in the judicial system, aimed at dismantling Plahotniuc’s networks of patronage but also impacting the Socialists, who to a large degree also profited from the previous status quo.The red line came over a last-minute change in the selection process of the prosecutor general proposed by Sandu on 6 November, which the Socialists claimed was unconstitutional and gave them the justification to put forward a motion of no confidence in the Sandu government. This was conveniently supported by the Democratic Party, who appeared threatened by an independent prosecutor’s office and saw an opportunity to return to power.Thus, the political will to reform proved insufficient in the absence of a clear strategy on how to address the concerns of the old regime that they would be prosecuted and their vested interests threatened. Here, ACUM’s lack of political experience let them down. With their hands tied from the beginning in a fragile coalition with the Socialists, ACUM were unable to prevent sabotage from within state institutions and their own coalition, and could not find consensus to proceed with more radical methods to tackle corruption.Less than two days after the Sandu government was out, a new government was sworn in on 14 November. Prime Minister Ion Chicu was an adviser to President Dodon before taking office and former minister of finance under the Plahotniuc-backed government of Pavel Filip, as part of a cabinet of ministers consisting largely of other presidential advisers and former high-level bureaucrats and ministers from the Plahotniuc era. The new governmentA top priority for the Chicu government is to convince the international community that it is independent from President Dodon, and that its ‘technocrats’ will keep the course of reforms of the Sandu government. This is critical to preserving the financial assistance of Western partners, which the Moldovan government heavily relies on, particularly with a presidential election campaign next year, when they will likely want to create fiscal space for various giveaways to voters.But within its first week in office, Chicu appears incapable of walking this line. Reverting to the initially proposed pre-selection process of prosecutor general signals that the post could be filled by a loyal appointee of President Dodon. Moreover, Chicu’s first visit abroad was to Russia, allegedly a major financial contributor of the Socialists’ Party. With the Socialists now holding the presidency, government, Chisinau mayoralty, and the parliament speaker’s seat, the danger of an increased Russian influence on key political decisions is very real.A government steered by President Dodon risks bringing Moldova back to where it was before June, with a political elite mimicking reforms while misusing power for private gains. The biggest danger is that instead of continuing the reform process to bring Moldova back on its European integration path, the new government may focus on strengthening the old patronage system, this time with President Dodon at the top of the pyramid.LessonsThis new minority government, supported by the Democrats, is a more natural one for President Dodon and therefore has more chances to survive, at least until presidential elections in autumn of 2020. Both the Socialists and the Democrats will likely seek to use this time to rebuild their own methods of capturing state resources. But with the Socialists relying on the Democrats’ votes in parliament, this is a recipe for further political instability.Similar to Moldova, several other states across the post-Soviet space such as Ukraine and Armenia have had new political forces come to power with the political will and mandate to carry out difficult reforms to strengthen rule of law and fight systemic corruption in their countries. What they all have in common is the lack of political experience of how to create change, while old elites, used to thinking on their feet to defend their vested interests, retain their connections and economic and political influence.Moldova is a good example of why political will needs to be backed up by clear strategy on how to deal with threatened vested interests in order for new political forces to be able to maintain themselves in power and reforms to be sustainable. When the chance comes again for fresh leaders to come to power, it is importantthey are politically prepared to use it swiftly and wisely. Full Article
as Kazakhstan: Reaching Out to Central Asian Neighbours By feedproxy.google.com Published On :: Wed, 04 Dec 2019 10:21:03 +0000 4 December 2019 Annette Bohr Associate Fellow, Russia and Eurasia Programme Despite its regional outreach, Kazakhstan’s diplomatic priority will remain Russia, China, and Europe. 2019-12-04-Kaz.jpg Kazakhstan's President Kassym-Jomart Tokayev, Kazakh Majilis Chairman Nurlan Nigmatulin and ex-president Nursultan Nazarbayev at an inauguration ceremony in parliament. Photo: Pavel AleksandrovTASS via Getty Images. Leaders of the resource-rich Central Asian region have the propensity to remain in power until mortality dictates otherwise. Much like the UK and Brexit, however, few wanted to see Central Asia’s longest reigning ruler, Kazakhstan’s septuagenarian president Nursultan Nazarbayev, crash out without a deal.The sudden departure of the country’s official leader of the nation with no clear succession plan could have led to investment chaos, intra-elite fighting and the unravelling in a matter of months of a system he had built over decades, à la Uzbekistan following the death of long-serving autocrat Islam Karimov in 2016.In order to avoid just such a ‘no-deal’ scenario and ensure the continuity of his policies, in March Nazarbayev carefully choreographed his own resignation and the election of a hand-picked successor, President Kassym-Jomart Tokayev, while retaining plum positions and powers for himself.Tokayev’s assumption of the presidency was accompanied by protesters in the streets, increasing wealth inequality, rising Sinophobia among rank-and-file Kazakhstanis, a hard-to-kick economic dependence on oil revenues and a lack of clarity as to which leader—the old or the new president—would actually be calling the shots. But, amidst this plethora of concerns, as argued in a recent Chatham House report, Kazakhstan: Tested by Transition, one bright spot has been the tangible growth of intra-Central Asian cooperation, with the Nazarbayev-Tokayev ruling duo appearing eager to improve the regional dialogue.Kazakhstan has long shaped its identity as a Eurasian state that has acted as more of an intermediary between Russia and Central Asia than as an integral part of the Central Asian region. But since 2017, in particular, Kazakhstan has been increasingly looking for opportunities to boost hitherto weak cooperation with its Central Asian neighbours. While this is first and foremost owing to the liberalization of Uzbekistan’s large market, there are other factors at work that get less airplay.One such factor is a perceptible disentangling from the Kremlin’s policy directions as Kazakhstan has come to view Russia’s foreign policy as increasingly neo-colonial. The example of the Russia-led Eurasian Economic Union is in many respects more off-putting than inspiring, and Nur-Sultan does not want to be locked tightly into the union’s economic orbit. And in distancing itself slightly from Moscow in order to limit Russian leverage in its affairs, Nur-Sultan has shown itself to be more open to Central Asian regional initiatives.As part of the leadership’s plan to offset oil dependence, Kazakhstan aspires to become the transport, telecommunications and investment hub for Eurasian integration. The intense focus on connectivity and the development of logistical arteries and infrastructure could have the knock-on effect of boosting trade within the Central Asian region and reducing transit times, which are currently greater than in most other parts of the globe.In addition, demographic trends and educational shifts that favour ethnic Kazakhs, together with a growing ethno-nationalist narrative, have allowed the state’s leadership to identify more closely with Kazakhstan’s common Central Asian heritage and, by extension, a common Central Asian region—although Kazakhstan’s leadership still remains eager to demonstrate that the country is not just another ‘stan’. The coming to power of President Mirziyoyev in Uzbekistan appears to have made Kazakhstan more aware of the interconnectedness of the two countries in terms of geographical location and potential economic complementarities, as well as culture and history.Not least, there is a growing recognition among the Central Asian states themselves—including isolationist Turkmenistan to a degree—that deepening regional trade is mutually beneficial, especially given the constraints associated with Russia’s economic problems. The strengthening of Kazakhstan’s ties with Uzbekistan has slowly kick-started regional cooperation as a whole: trade turnover between the Central Asian states in 2018 grew by 35 per cent on the previous year.But both Kazakhstan and Uzbekistan are keen to stress that there is no discussion of integration or institutionalization, not least because previous attempts at integration have been overtaken by Russia, leaving Central Asia without its own coordinating body.The official consensus in Kazakhstan is that Uzbekistan’s economic reforms after years of isolation will spur ‘a healthy rivalry’ and ultimately boost Kazakhstan’s own economy, in so far as the competition for foreign investment will require both countries to work harder to improve their respective business and regulatory environments.At the unofficial level, however, some Kazakhstani analysts view Uzbekistan’s rise as potentially unprofitable, given the possible diversion of some investments and market activity from Kazakhstan to Uzbekistan. Moreover, Uzbekistan has the advantage of having undergone a clear change of executive, while it remains unclear which developments await Kazakhstan once First President Nazarbayev leaves the scene for good.It can certainly be argued that Uzbekistan does pose a potential threat in the long-term to Kazakhstan’s entrenched position as Central Asia’s economic powerhouse: Uzbekistan’s population is one-and-a-half times bigger, even if its nominal GDP is three times smaller. Uzbekistan has a bigger market and a well-developed industrial sector, and is already the regional leader in terms of security. But it is not as though the world’s interest is moving from Kazakhstan to Uzbekistan; rather, Uzbekistan is in the process of trying to catch up.Despite this relatively upbeat picture, Kazakhstan’s combined trade with the other Central Asian states accounts for less than 5 per cent of its total volume of foreign trade—a figure that cannot begin to equal its trade with Russia, China, and Europe. As a result, Kazakhstan will continue to give greater importance to positioning itself as a global player than as a regional leader.This article was originally published in The Diplomat. Full Article
as Three Challenges for UK Peacebuilding Policy in the South Caucasus After Brexit By feedproxy.google.com Published On :: Tue, 21 Jan 2020 09:24:44 +0000 21 January 2020 Laurence Broers Associate Fellow, Russia and Eurasia Programme @LaurenceBroers Building on the legacies of a long-term British investment in a peace strategy for the South Caucasus is a realistic and attainable goal. 2020-01-21-NK.jpg A building in Nagorny Karabakh flies the flag of the self-proclaimed republic. 'Abkhazia, South Ossetia and Nagorny Karabakh have evolved into examples of what scholars call "de facto states" that, to differing degrees, control territory, provide governance and exercise internal sovereignty,' writes Laurence Broers. Photo: Getty Images. What does Britain’s departure from the EU mean for the country’s policy towards the South Caucasus, a small region on the periphery of Europe, fractured by conflict? Although Britain is not directly involved in any of the region’s peace processes (except in the case of the Geneva International Discussions on conflicts involving Georgia, as an EU member state), it has been a significant stakeholder in South Caucasian stability since the mid-1990s.Most obviously, Britain has been the single largest foreign investor in Caspian oil and gas. Yet beyond pipelines, Britain also has been a significant investor in long-term civil society-led strategies to build peace in the South Caucasus.Through what was then the Global Conflict Prevention Pool, in the early 2000s the Department for International Development (DfID) pioneered large-scale peacebuilding interventions, such as the Consortium Initiative, addressing Armenian-Azerbaijani conflict, in 2003-09. These built civic networks in the South Caucasus and partnerships with British-based NGOs.This experience left a strong intellectual legacy. British expertise on the South Caucasus, including specific expertise on its conflicts, is highly regarded in the region and across the world.There is also a strong tradition of British scholarship on the Caucasus, and several British universities offer Caucasus-related courses. Through schemes such as the John Smith Fellowship Trust, the Robert Bosch Stiftung Academy Fellowship at Chatham House and Chevening Scholarships, significant numbers of young leaders from the South Caucasus have spent time in British institutions and built effective relationships within them.Three challengesThis niche as a champion of long-term, strategic peacebuilding and repository of area-specific knowledge should not be lost as Britain’s relationship with the EU and regional actors evolves. This can be ensured through awareness of three challenges confronting a post-Brexit Caucasus policy.The first challenge for London is to avoid framing a regional policy in the South Caucasus as an extension of a wider ‘Russia policy’. Deteriorating Russian-British relations in recent years strengthen a tendency to view policies in the European neighbourhood through the traditional prisms of Cold War and Russian-Western rivalries.Yet an overwhelming focus on Russia fails to capture other important aspects of political developments in South Caucasus conflicts. Although often referred to as ‘breakaway’ or ‘occupied’ territories, Abkhazia, South Ossetia and Nagorny Karabakh are not ungoverned spaces. They have evolved into examples of what scholars call ‘de facto states’ that, to differing degrees, control territory, provide governance and exercise internal sovereignty.Few disagree that these entities would not survive without external patronage. But neither does that patronage explain their sustainability on its own. Russia-centricity diminishes Britain’s latitude to engage on the full range of local drivers sustaining these entities, contributing instead to less effective policies predicated on competition and containment.A second and related challenge is to maintain and develop Britain’s position on the issue of engaging populations in these entities. De facto states appear to stand outside of the international rules-based system. Yet in many cases, their civil societies are peopled by skilled and motivated activists who want their leaders to be held accountable according to international rules.Strategies of isolation ignore these voices and contribute instead to fearful and demoralized communities less likely to engage in a transformation of adversarial relationships. Making this case with the wider international community, and facilitating the funding of local civil societies in contested territories, would be important steps in sustaining an effective British policy on the resolution of conflicts. The third challenge for Britain is to maintain a long-term approach to the conflicts of the South Caucasus alongside potential short-term imperatives in other policy fields, as relationships shift post-Brexit.In this fluid international environment, the Foreign and Commonwealth Office has a role to play both as an internal champion of a long-term peacebuilding strategy and a coordinator of British efforts with those of multilateral actors engaged in the South Caucasus. These include the United Nations, the EU’s Special Representative for the South Caucasus and the Crisis in Georgia and OSCE’s Special Representative for the OSCE Chairperson-in-Office for the South Caucasus, all of which have built relationships with relevant actors on the ground.RecommendationsBritain’s niche as a champion and advocate of a strategic approach to peaceful change can be secured post-Brexit in the following ways. First, in-house expertise is crucial to effective peacebuilding programming. The Foreign Office’s research analysts play a vital role in generating independent internal advice and liaising with academic and NGO communities. Their role could be supplemented by the reinstatement of a regional conflict adviser post, based in Tbilisi, tasked with strengthening Britain’s regional presence on conflict issues and coordinating policy at a regional level.This post, with a remit to cover conflicts and build up area knowledge and relationships can contribute significantly to working closely with local civil societies, where so much expertise and knowledge resides, as well as other stakeholders.Second, programming should build in conflict sensitivity by dissociating eligibility from contested political status. This can encourage local populations to take advantage of opportunities for funding, study, comparative learning and professional development irrespective of the status of the entity where they reside.The Chevening Scholarships are an excellent example, whereby applicants can select ‘South Caucasus’ as their affiliated identity from a drop-down menu. This enables citizens from across the region to apply irrespective of the status of the territory in which they live. Finally, a holistic understanding of peace is crucial. Programming in unrecognized or partially-recognized entities should acknowledge that effective peacebuilding needs to embrace political dynamics and processes beyond cross-conflict contact and confidence building. Local actors in such entities may find peacebuilding funding streams defined exclusively in terms of cross-conflict contact more politically risky and ineffective in addressing domestic blockages to peace.While cross-conflict dynamics remain critical, ‘single-community’ programming framed in terms of civic participation, inclusion, civil society capacity-building, minority and human rights in contested territories, and building the confidence from within to engage in constructive dialogue, are no less important.The ’global Britain’ promised by Brexit remains a fanciful idea. Quiet, painstaking work to build on the legacies of a long-term British investment in a peace strategy for the South Caucasus, on the other hand, is a realistic and attainable goal. Full Article

as Could Zelenskyy’s Strategy for Donbas Lead Ukraine Into a Kremlin Trap? By feedproxy.google.com Published On :: Fri, 14 Feb 2020 09:54:05 +0000 14 February 2020 Kataryna Wolczuk Associate Fellow, Russia and Eurasia Programme Google Scholar Hanna Shelest Member of the Board, Foreign Policy Council 'Ukrainian Prism' In pursuit of peace in the war-torn region, the Ukrainian president’s short-term, tactical approach is vulnerable in the face of Russia’s long-term strategy. 2020-02-14-Zelenskyy.jpg Volodymyr Zelenskyy attends a ceremony welcoming Ukrainians who were freed by pro-Russian rebels during a prisoner exchange. Photo: Getty Images. One of the key messages at the heart of Volodymyr Zelenskyy’s presidential campaign in 2019 was a very simple one: peace in Donbas, the war-torn region of Ukraine where Russian-supported separatists continue to fight a war against the Kyiv government. Zelenskyy’s message was based on the assumption that if a ceasefire could be respected, and all Ukrainian prisoners-of-war could return home, then peace would have been achieved.Nine months after Zelenskyy’s inauguration and two months after his first Normandy Four summit (which brings together Germany and France with Ukraine and Russia to discuss Donbas), it appears more likely that this approach will lead Ukraine into a Russian trap.Zelenskyy’s very immediate objectives and the tactics used to achieve them contrast with those of the previous president, Petro Poroshenko. Zelenskyy has pointedly avoided naming Russia as an aggressor and has focused on humanitarian issues and seeking compromise wherever possible, including in legal cases that Russia has already lost in international courts.In contrast, President Poroshenko prioritised the security agenda as a precondition for any political settlement, encapsulated in the notion of ‘no elections without security guarantees’. This focused on regaining control of the border and the demilitarization of the separatist-controlled territories. At the same time, Poroshenko sought remedial action for Russian aggression through international courts. Kyiv is testing the Kremlin’s real intentions with a series of small steps without clearly communicating its overarching objectives. This has triggered considerable social disquiet, manifested by demonstrations in Kyiv and other cities as part of the ’No capitulation’ campaign. This wave of criticism forced Zelenskyy’s team to name certain red lines, which he promised he would not cross (‘we don’t trade territories and people’) in pursuit of conflict resolution.Other key issues, such as Ukraine’s relations with the EU, future NATO membership, language issues and any possible ‘special status’ for Donbas, have been left undefined.Two months since the Normandy summit, the number of casualties has not declined. It is increasingly difficult for Zelenskyy to argue that disengagement by Ukraine’s army from the contact line in three locations, which was a precondition for the December Normandy Four meeting, is a way to achieve peace.The separatists continue to significantly impede the OSCE’s special monitoring mission, a full ceasefire is not being observed and there are numerous reports of heavy weapons movements closer to the contact line in the areas outside Kyiv’s control. These issues are particularly problematic as control over the border with Russia is essential for the demilitarization of the ‘people’s republics’, which is a prerequisite for the safe reintegration of these areas.Conducting local elections in autumn 2020 is a top priority for the new team, but it is clear that even if Ukraine regains control of its border, the presence of Russian military personnel and weaponry in Donbas threatens the prospect of free and fair elections (which themselves raise the further issue of how to ensure the integrity of the votes).Russia’s strategySo despite Zelenskyy’s pacifist rhetoric, hopes and ambitions, his plans are far from being realized or, in fact, realizable. This is because these plans are at odds with Russia’s strategic objective, which is for Donbas to be conferred a status whereby it is de jure within Ukraine but de facto under Russian control and influence.Zelenskyy’s media-friendly appearance in Paris in December 2019 could not mask the fact that the Normandy Four talks exposed the weakness of Ukraine’s position and the growing influence of Russia’s approach, particularly in the context of a disengaged UK and US, a Germany increasingly tired of this conflict, and a French president who is looking to accommodate Russian preferences.Indeed, Vladimir Putin was able to exploit the opportunity to apply his favoured formula for conducting foreign policy: highly personalized informal interactions, which seek specific political concessions from a cornered partner and which are short on transparent, stable and law-based solutions. The Paris meeting of the Normandy Four in December 2019 clearly demonstrated that simply sitting down and talking to Putin is not a magic pill to end the conflict, an idea frequently expressed by Zelenskyy.In 2020, the strongest clue as to what Putin’s plans for Ukraine might be is the appointment of Dmitry Kozak as the main curator of the ‘Ukraine file’ (meaning Donbas and Crimea), replacing Vladislav Surkov, his long-time competitor for the role. The next Normandy meeting is expected in April 2020, and Kyiv should be aware of the possible pitfalls.While Kozak is perceived by some as a more pragmatic and less aggressive counterpart, his past tells a different story. In fact, he was the architect of the long-term strategy for Moldova, which centred on the federalization of Moldova and the reincorporation of the separatist region of Transnistria into Moldova.The presence of Russian military forces stationed on the ground there amounts to ‘armed suasion’ – using a military presence to demand political concessions from Moldova. The so-called ‘Kozak memorandum’ – which de facto re-writes the constitution of Moldova – contains a detailed explanation of that strategy.Kozak could try to deliver a similar situation for Ukraine. Less emphasis is being put on specific terms (federalization vs. special status) but the overarching aims are unchanged since 2014, in the same way they have been in Moldova since 2003. Kozak is a man who can play the long game, while the team of the Ukrainian president chases quick successes without calculating long-term risks. This could be a dangerous combination.The ‘human-centric approach’ to resolving the conflict followed by President Zelenskyy is a double-edged sword. The focuses on humanitarian issues and readiness for big compromises are clear positive signals to Western partners and supporters of Zelenskyy’s Servant of the People party. But prioritizing humanitarian issues over national security considerations could easily lead Ukraine into a Russian trap, which does not so much rely on a massive military assault but envisages creeping control over Ukraine’s future as its ultimate goal.

as Lukashenka’s Commitment to Belarusian Sovereignty Is Overstated By feedproxy.google.com Published On :: Tue, 18 Feb 2020 15:56:54 +0000 18 February 2020 Ryhor Astapenia Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme @ryhorastapenia LinkedIn Although President Lukashenka has recently shown assertiveness in relations with Russia, overall he has done very little to ensure his country’s freedom of action. 2020-02-18-LP.jpg Putin and Lukashenka play ice hockey in Sochi after a day of talks in February. Photo: Getty Images. Earlier this month, US Secretary of State Mike Pompeo became the highest-ranking US official to visit Belarus since Bill Clinton in 1994. After meetings with Belarusian President Alexander Lukashenka – who Condoleezza Rice once memorably described as ‘Europe’s last dictator’ – Pompeo said he was ‘optimistic about our strengthened relationship’. The EU and its member states have also changed their tune, at least a little. Previously, prosecutions of democratic activists led to sanctions against the Lukashenka regime. But his less-than-liberal manner of governance did not prevent him from visiting Austria last November or from receiving invitations to Brussels. Eight years ago, most EU contacts with Belarusian officials were frozen. Now, Western diplomats regularly meet with Belarusian officials again. This year, a US ambassador to Belarus will be appointed after a 12-year break.The West is also more willing to support Belarus financially. The European Bank for Reconstruction and Development invested a record-breaking $433 million in the country in 2019. The European Investment Bank only began working with the country in 2017 but already has a portfolio of $600 million.Certain policymakers in the EU and US now, at least publicly, appear to regard Lukashenka as one of the sources of regional security and a defender of Belarusian sovereignty against Russia.There is some truth in this. He has taken a neutral position in Russia’s conflict with Ukraine, and he has consistently resisted pressure from the Kremlin to establish a military base in Belarus.Now, amid Moscow’s demands for deeper integration in exchange for the continuation of Russian energy subsidies, Lukashenka has shown reluctance to sell his autonomy. In a token attempt to portray sovereignty Belarus even started buying oil from Norway, although this makes no economic sense.But Lukashenka’s long-term record shows he has done little to ensure the country’s sovereignty. Lukashenka has resisted reforms that would have strengthened the economy (because they would have weakened his own position). The political system is also dependent on Russia because Lukashenka has been unwilling to build better relations with the West. Belarusians are still strongly influenced by Russian culture and media because the authorities marginalize their own national identity.Since the conflict in Ukraine in 2014, Lukashenka’s primary goal has not been to strengthen the sovereignty of Belarus, but to preserve his absolute control over the country.For example, when in 2018 Russia started pressing Belarus to deepen its integration in order to retain economic support, Minsk did not reject this approach outright; instead, it discussed no less than 31 ‘road maps’ for deepening integration for more than a year, hoping to receive more benefits. For Lukashenka, greater dependency on Russia is a matter of price and conditions, not principle. None of this is to say Belarus has illusions about Russia. It is just that Lukashenka does not take long-term steps to protect the country’s sovereignty or to strengthen relations with the West.Belarus needs to start economic reform with the support of the International Monetary Fund, but this cannot happen without Lukashenka’s genuine commitment to transform the economy. Absence of cross-sectoral reform has led to the deterioration of the education system as well as unprecedented emigration. Few Belarusian experts are optimistic about their country’s future. Lukashenka knows all this, but does not change his system, fearing it would damage the stability of his regime. The West should therefore adopt a broader policy. Lukashenka is unlikely to still be president in 10–15 years, so policymakers should develop relations with the broader ruling elite, which will remain after he leaves, and try to be present in Belarus as much as possible helping it to improve public governance and develop private businesses.The West should also support the country’s civil society and independent media, for whom Belarusian independence is a matter of principle rather than something to be bargained away.Lukashenka may be a strong leader, but the state he has built is weak.

as Sanctions on Russia: Will Asia Help? By feedproxy.google.com Published On :: Wed, 08 Apr 2020 10:00:02 +0000 Invitation Only Research Event 17 April 2020 - 10:00am to 11:30am Event participants Maria Shagina, CEES Postdoctoral Fellow, Center for Eastern European Studies, University of ZurichChair: Richard Connolly, Associate Fellow, Russia and Eurasia Programme, Chatham House It has been nearly six years since the West imposed sanctions on Russia, targeting Russia's energy, defence and financial sectors. The sanctions exposed Russia's key vulnerabilities - dependence on Western capital and advanced technology, with knock-on effects in other sectors.In an effort to offset the impact of sanctions, Russia has attempted a diversification strategy to non-Western states. The Asia-Pacific has emerged as a new export market for hydrocarbons and weapons, and as the main alternative to Western capital. Russia's self-proclaimed 'turn to the East' is intended to alleviate the sanctions burden and buy valuable time to come up with long-term solutions; but it has come at a high cost. In this discussion, Maria Shagina will examine the ways in which Asian states have helped mitigate the impact of Western sanctions and the pitfalls associated with it, while assessing the implications of Russia's pivot to Asia on its import substitution policy, and the effectiveness of sanctions overall.

However, the influence of the governing elite in Belarus is growing again. It seems likely that the current governing class could rule the country after Lukashenka leaves. It is thus important to study Belarusian elites not only to understand the current regime, but also to better forecast and navigate the political system that will one day replace it. This study group aims to disentangle how the Belarusian political system works, outline the types of individuals that make up the Belarusian ruling elite, assess the interaction of the elite and institutions with the West, and suggest changes that Western political actors might make to their approach to the Belarusian ruling class.

President Zelenskyy, who came to power in May 2019, promised to end the war with Russia and bring peace to Ukraine.Since assuming office, Zelenskyy has managed to revive the Normandy Format talks, complete military disengagement at three points along the line of contact and negotiate the release of over a hundred Ukrainians held as prisoners of war in Russia. However, ceasefire violations continue to occur frequently.Looking at the origins of the armed conflict in Donbas and the region’s economic role in Ukraine’s economy, this event discusses the prospects for conflict resolution. Do the recent events signify an opportunity for peace? Does Zelenskyy have a viable plan for re-integrating Donbas or will the region be cut off from mainland Ukraine for the foreseeable future?The speakers assess the strategy and track record of the Ukrainian government and its Western allies in bringing parts of the occupied Donbas under Kyiv’s control. They also review possible policy implications of the COVID-19 pandemic for the conflict.

as ICC’s Influence Can Be Strengthened by Ukraine’s Case By feedproxy.google.com Published On :: Wed, 22 Apr 2020 22:27:35 +0000 22 April 2020 Kateryna Busol Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme @KaterynaBusol LinkedIn Second in a two-part series analysing why Ukraine’s attempts at international justice are worth taking - and outlining how the impact goes far beyond just the Russia-Ukraine conflict. Part two examines Ukraine’s appeal to the International Criminal Court (ICC) to seek individual criminal responsibility of the alleged perpetrators of the gravest crimes in occupied Crimea and eastern Ukraine. 2020-04-23-Ukraine-Anniversary-Conflict Marking the Day of The National Flag of Ukraine, a day before celebrations of the anniversary of state independence. Photo by ANATOLII STEPANOV/AFP via Getty Images. The recognition by Ukraine of the jurisdiction of the International Criminal Court (ICC) to consider grave crimes allegedly perpetrated in its territory has led to the ICC Prosecutor’s preliminary examination identifying a wave of alleged war crimes and crimes against humanity.There are claims of persecution, forced conscription, deportation, sham trials, enforced disappearances, and property seizure - in Crimea. As well as killings, torture, inhuman treatment, sexual violence, and indiscriminate shelling - in Donbas. The court now needs to decide whether to open a full investigation which could lead to charges against specific individuals, as in the trial currently taking place in the Netherlands over MH-17.However, the ICC does remain a court of last resort as Ukraine retains the principal power to prosecute grave violations perpetrated in its eastern regions and Crimea, with the court only stepping in if Ukraine (or another court with jurisdiction) is either unwilling or unable to do so.As the evidence mounts up, Ukrainian investigators, prosecutors and judges are becoming more open to cooperation with foreign experts, law firms, human rights NGOs and younger domestic professionals - a significant proportion of whom are women.Transformation shows determinationThis is an unusual shift, given the rigid hierarchical nature of post-Soviet institutions, with elderly males in most of the top positions. The transformation shows the determination to see perpetrators of crimes in Crimea and Donbas tried by the ICC, with joint professional development trainings and joint communications about the alleged crimes.Ukraine has also been strengthening its institutions. The Prosecutor’s Office of the Autonomous Republic of Crimea has been improving quality control of its war crime proceedings, and has taken a strong pro-ICC stance. The Office of the Prosecutor General established a special department to monitor the armed conflict proceedings, and two specialised war crime units have been formed in Donbas.Although too early to assess progress - given recent prosecution reform and that much-needed legislation on international crimes is still pending – these are promising signs of Ukraine’s intent to take a specialised approach to armed conflict violations. And Ukrainian civil society organisations are also playing a more important role, documenting alleged crimes and sending evidence to the ICC.Any intervention by the ICC in Ukraine also has a considerable impact on the wider dynamics of addressing international crimes, further extending the court’s reach beyond a focus on Africa which has attracted widespread criticism since it began in 2002.The ICC has already opened investigations in Georgia, Bangladesh/Myanmar, and Afghanistan, with preliminary examinations in Colombia, Venezuela, Iraq/UK, Palestine, and The Philippines. But the Ukrainian case would further develop the European subtleties of the court’s jurisprudence.Although the ICC is currently investigating the 2008 Russia-Georgia war, the active phase of that armed conflict lasted for just five days whereas Russia’s military involvement in Ukraine has been ongoing for the six years. The temporal difference in no way diminishes the suffering of victims and the necessity for the proper investigation, prosecution and compensation in the Georgian context.And yet, going by even the preliminary findings of the ICC prosecutor, the spectrum of war crimes and crimes against humanity allegedly perpetrated in Ukraine is much wider. Some incidents, such as the illegal construction of the Crimean Bridge, is an amalgam of the violations against property, cultural heritage and the environment. Cumulatively, the Ukrainian and Georgian cases would substantially contribute to the development of the court’s emerging European lenses.The Russia-Ukraine armed conflict is also the first instance of armed hostilities of such magnitude and duration in Europe since World War II and the Yugoslav Wars. The ICC’s readiness to take on such geopolitically challenging cases which leave itself open to attack will be tested.But by examining new contexts - including Ukraine - the ICC would develop a more layered reading of the nature and scope of the crimes it works on. For example, alleged indoctrination and use of children by armed groups in eastern Ukraine is likely to differ from the known practices of abducting and recruiting child soldiers in Africa.Investigating evidence of Russia’s persecution of pro-Ukrainian activists - forcing them out of Crimea - coupled with the creation of favourable conditions for Russian citizens to relocate to Crimea could lead to proving the existence of a policy of mass colonisation of the peninsula - adding new layers to the court’s jurisprudence on population displacement. And previously under-prosecuted crimes may come to the fore, such as attacks on cultural property or causing the destruction of the environment.Although the ICC proceedings on Ukraine – along with those being held by the International Court of Justice (ICJ) - are unlikely to bring immediate results, Ukraine has developed an international adjudication strategy based on the available viable options and what can be practically delivered.The simple act of a reputed international court outlining Russia’s alleged violations in Crimea and Donbas and naming those individually responsible would be an impactful achievement in itself, regardless of whether Russia pays any attention or compensation.And any international judgments or those of domestic courts such as the Dutch MH-17 proceedings and Russia’s response - predicted to be non-compliance - is an important argument for continuing sanctions against Russia over its conduct in Ukraine.The mutually reinforcing effect of both the Crimea and Donbas proceedings within Ukraine and at international courts should not be underestimated. These investigations into war crimes, terrorism and human rights issues are deeply relevant - not only for the conflict itself, but also for the development of international law.Part One of this series assesses Ukraine’s efforts to hold Russia accountable as a state at the International Court of Justice (ICJ).

as Plasma membrane asymmetry of lipid organization: fluorescence lifetime microscopy and correlation spectroscopy analysis [Methods] By feedproxy.google.com Published On :: 2020-02-01T00:05:23-08:00 A fundamental feature of the eukaryotic cell membrane is the asymmetric arrangement of lipids in its two leaflets. A cell invests significant energy to maintain this asymmetry and uses it to regulate important biological processes, such as apoptosis and vesiculation. The dynamic coupling of the inner or cytoplasmic and outer or exofacial leaflets is a challenging open question in membrane biology. Here, we combined fluorescence lifetime imaging microscopy (FLIM) with imaging total internal reflection fluorescence correlation spectroscopy (ITIR-FCS) to differentiate the dynamics and organization of the two leaflets of live mammalian cells. We characterized the biophysical properties of fluorescent analogs of phosphatidylcholine, sphingomyelin, and phosphatidylserine in the plasma membrane of two mammalian cell lines (CHO-K1 and RBL-2H3). Because of their specific transverse membrane distribution, these probes allowed leaflet-specific investigation of the plasma membrane. We compared the results of the two methods having different temporal and spatial resolution. Fluorescence lifetimes of fluorescent lipid analogs were in ranges characteristic for the liquid ordered phase in the outer leaflet and for the liquid disordered phase in the inner leaflet. The observation of a more fluid inner leaflet was supported by free diffusion in the inner leaflet, with high average diffusion coefficients. The liquid ordered phase in the outer leaflet was accompanied by slower diffusion and diffusion with intermittent transient trapping. Our results show that the combination of FLIM and ITIR-FCS with specific fluorescent lipid analogs is a powerful tool for investigating lateral and transbilayer characteristics of plasma membrane in live cell lines.
