rom Resetting Africa-Europe relations: From self-deception to economic transformation By www.chathamhouse.org Published On :: Wed, 16 Oct 2024 10:47:14 +0000 Resetting Africa-Europe relations: From self-deception to economic transformation 28 October 2024 — 12:30PM TO 1:30PM Anonymous (not verified) 16 October 2024 Chatham House and Online Experts assess the status of ties between Africa and Europe in a rapidly changing world, launching a new book that explores how misconceptions in the relationship can harm Africa’s economic agenda. The relationship between Africa and Europe has long been shaped by colonial legacies, power imbalance and shifting geopolitical interests.Almost three years on from the last EU-AU summit in Brussels in February 2022, questions remain over the delivery of headline commitments under the continent-to-continent partnership – ranging from the EU’s Global Gateway infrastructure strategy to wider climate financing promises.As Africa seeks to strengthen its standing on the global stage, marked by the African Union’s upcoming debut at the G20 summit in November, a critical reassessment of these dynamics is needed to examine whether the continent’s relationship with Europe can overcome stigmatized narratives in search of genuine economic benefit.At this event, which launches a new book by Professor Carlos Lopes: The Self-Deception Trap: Exploring the Economic Dimensions of Charity Dependency within Africa-Europe Relations, speakers assess the prospects for a transformative shift towards a more equitable and mutually beneficial Africa-Europe partnership.

rom The Arg-293 of Cryptochrome1 is responsible for the allosteric regulation of CLOCK-CRY1 binding in circadian rhythm [Computational Biology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Mammalian circadian clocks are driven by transcription/translation feedback loops composed of positive transcriptional activators (BMAL1 and CLOCK) and negative repressors (CRYPTOCHROMEs (CRYs) and PERIODs (PERs)). CRYs, in complex with PERs, bind to the BMAL1/CLOCK complex and repress E-box–driven transcription of clock-associated genes. There are two individual CRYs, with CRY1 exhibiting higher affinity to the BMAL1/CLOCK complex than CRY2. It is known that this differential binding is regulated by a dynamic serine-rich loop adjacent to the secondary pocket of both CRYs, but the underlying features controlling loop dynamics are not known. Here we report that allosteric regulation of the serine-rich loop is mediated by Arg-293 of CRY1, identified as a rare CRY1 SNP in the Ensembl and 1000 Genomes databases. The p.Arg293His CRY1 variant caused a shortened circadian period in a Cry1−/−Cry2−/− double knockout mouse embryonic fibroblast cell line. Moreover, the variant displayed reduced repressor activity on BMAL1/CLOCK driven transcription, which is explained by reduced affinity to BMAL1/CLOCK in the absence of PER2 compared with CRY1. Molecular dynamics simulations revealed that the p.Arg293His CRY1 variant altered a communication pathway between Arg-293 and the serine loop by reducing its dynamicity. Collectively, this study provides direct evidence that allosterism in CRY1 is critical for the regulation of circadian rhythm. Full Article

rom Biochemical and biophysical analyses of hypoxia sensing prolyl hydroxylases from Dictyostelium discoideum and Toxoplasma gondii [Molecular Biophysics] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 In animals, the response to chronic hypoxia is mediated by prolyl hydroxylases (PHDs) that regulate the levels of hypoxia-inducible transcription factor α (HIFα). PHD homologues exist in other types of eukaryotes and prokaryotes where they act on non HIF substrates. To gain insight into the factors underlying different PHD substrates and properties, we carried out biochemical and biophysical studies on PHD homologues from the cellular slime mold, Dictyostelium discoideum, and the protozoan parasite, Toxoplasma gondii, both lacking HIF. The respective prolyl-hydroxylases (DdPhyA and TgPhyA) catalyze prolyl-hydroxylation of S-phase kinase-associated protein 1 (Skp1), a reaction enabling adaptation to different dioxygen availability. Assays with full-length Skp1 substrates reveal substantial differences in the kinetic properties of DdPhyA and TgPhyA, both with respect to each other and compared with human PHD2; consistent with cellular studies, TgPhyA is more active at low dioxygen concentrations than DdPhyA. TgSkp1 is a DdPhyA substrate and DdSkp1 is a TgPhyA substrate. No cross-reactivity was detected between DdPhyA/TgPhyA substrates and human PHD2. The human Skp1 E147P variant is a DdPhyA and TgPhyA substrate, suggesting some retention of ancestral interactions. Crystallographic analysis of DdPhyA enables comparisons with homologues from humans, Trichoplax adhaerens, and prokaryotes, informing on differences in mobile elements involved in substrate binding and catalysis. In DdPhyA, two mobile loops that enclose substrates in the PHDs are conserved, but the C-terminal helix of the PHDs is strikingly absent. The combined results support the proposal that PHD homologues have evolved kinetic and structural features suited to their specific sensing roles. Full Article

rom Duterte’s Victory Is Cry for Help From Those Left Behind in Philippines By www.chathamhouse.org Published On :: Thu, 12 May 2016 15:01:57 +0000 Duterte’s Victory Is Cry for Help From Those Left Behind in Philippines Expert comment sysadmin 12 May 2016 But large support for mainstream parties and a mature democratic system should keep the country from slipping back towards authoritarianism. — Rodrigo Duterte prepares to vote inside a polling precinct on 9 May 2016 in Davao. Photo by Getty Images. The victory of political outsider Rodrigo Duterte in the 2016 Philippines’ elections is proof that a significant minority of the country’s population feels left behind by its recent economic success and estranged from its political elite. However the results of the elections as a whole suggest that most voters opted for a continuation of the current government’s policies.Duterte looks almost certain to be inaugurated as the next president of the Philippines on 30 June. The country’s presidential voting system – a single round, first-past-the-post election – delivered victory to a populist outsider with 39 per cent support. Two candidates advocating a continuation of the current government’s policies − the Liberal Party’s Mar Roxas and independent Grace Poe − polled a combined 45 per cent. The long-standing factionalism within Philippines elite politics split the ‘anti-Duterte’ vote.Changing the conversationThe contrast between Duterte and Roxas could hardly be greater. Mar Roxas is the grandson of the first president of an independent Philippines, a graduate of Wharton Business School and a former investment banker in the US. Rodrigo Duterte is a political outsider with an electoral base geographically almost as far from Manila as is possible to get in the Philippines: the city of Davao on the island of Mindanao.The story of Duterte’s victory is the story of how ‘Duterte managed to change the national conversation from poverty towards crime and corruption,’ says Marites Vitug, editor-at-large of one of the Philippines’ most popular online news sites, Rappler. In January, Duterte was running fourth in opinion polls but a strategy that positioned him as the only opponent to the Manila elite gave him victory. This is the first time a provincial official has made it to the top job.The headline figures tell us that the Philippines’ economy has done very well under President Benigno Aquino. Between 2010 and 2014, growth averaged 6.3 per cent per year. That fell to a still-impressive 5.8 per cent last year but is expected to pick up this year and next, according to the Asian Development Bank. Growth in agriculture, however, is significantly slower and rural areas feel left behind. While economic growth is benefiting the majority, inequality is worsening and resentment rising in poor villages. The contrast between the metropolitan sophistication of the Makati district in Manila and life in faraway provinces such as Duterte’s Mindanao is widening.Ironically the Philippines’ economic success is a part of the explanation for the defeat of the ‘mainstream’ presidential candidates. Crime and corruption may have become more important issues simply because more voters have become better off and therefore more likely to be concerned about crime and corruption than before. It’s also undeniable that Duterte has a record for getting things done. Human rights groups rightly criticize his (at best) tolerance of the extra-judicial killing of alleged criminals but his repeated re-election as mayor demonstrates that many citizens are prepared to accept that in exchange for improved personal security. A surprising number of Manila residents have actually moved to Davao because of its better quality of life.Traditional power basesHowever, the results as a whole suggest a narrow majority in favour of current policies. In the vice-presidential race, the Liberal Party candidate Leni Robredo is narrowly ahead of Ferdinand ‘Bongbong’ Marcos, the son of the eponymous former president. Like Duterte she is regarded as a successful mayor of a well-run city, Albay. Duterte’s running mate Alan Cayetano received just 14 per cent of the vote.In the senate election, Liberals won five of the 12 seats being contested, with a party- backed independent winning a sixth. The opposition, even with boxing champion and national idol Manny Pacquiao running for the United Nationalist Alliance, won four.Taken as a whole, the results show the enduring nature of traditional Philippines power bases. The country’s many islands and distinct linguistic and cultural regions are virtual fiefs in which families and big bosses can wield almost total power through control of local authorities, businesses, the courts and security forces.Threat to democracy?It’s easy to forget that the election of Ferdinand Marcos in 1965 was originally welcomed as a challenge to the traditional elites of Philippine politics. The same accolades are currently greeting Duterte. Could they presage a return to the Philippines’ bad old days?This seems less likely. Philippine democracy has matured considerably since Marcos declared martial law in 1972. There is a substantial, and vocal, middle class with experience of mobilizing against ‘bad’ presidents. There will also be pressures from international investors and the Philippines’ treaty ally, the United States, for better governance.The Philippines will chair the Association of Southeast Asian Nations next year. That will put Duterte in the international spotlight as host of several international meetings – including the East Asia Summit attended by, among others, the presidents of China, Russia and the US. Since his victory Duterte has promised to act with decorum in office and declared that his election campaign antics were just a ploy to attract attention. Some leaders in Southeast Asia will use his victory to buttress their arguments against allowing their people to freely vote. It’s up to Duterte to decide whether he wants to be an advertisement for – or an argument against – democracy.To comment on this article, please contact Chatham House Feedback Full Article

rom Biochemical transformation of bacterial lipopolysaccharides by acyloxyacyl hydrolase reduces host injury and promotes recovery [Enzymology] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Animals can sense the presence of microbes in their tissues and mobilize their own defenses by recognizing and responding to conserved microbial structures (often called microbe-associated molecular patterns (MAMPs)). Successful host defenses may kill the invaders, yet the host animal may fail to restore homeostasis if the stimulatory microbial structures are not silenced. Although mice have many mechanisms for limiting their responses to lipopolysaccharide (LPS), a major Gram-negative bacterial MAMP, a highly conserved host lipase is required to extinguish LPS sensing in tissues and restore homeostasis. We review recent progress in understanding how this enzyme, acyloxyacyl hydrolase (AOAH), transforms LPS from stimulus to inhibitor, reduces tissue injury and death from infection, prevents prolonged post-infection immunosuppression, and keeps stimulatory LPS from entering the bloodstream. We also discuss how AOAH may increase sensitivity to pulmonary allergens. Better appreciation of how host enzymes modify LPS and other MAMPs may help prevent tissue injury and hasten recovery from infection. Full Article
rom Polydisperse molecular architecture of connexin 26/30 heteromeric hemichannels revealed by atomic force microscopy imaging [Protein Structure and Folding] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 Connexin (Cx) protein forms hemichannels and gap junctional channels, which play diverse and profound roles in human physiology and diseases. Gap junctions are arrays of intercellular channels formed by the docking of two hemichannels from adjacent cells. Each hexameric hemichannel contains the same or different Cx isoform. Although homomeric Cxs forms have been largely described functionally and structurally, the stoichiometry and arrangement of heteromeric Cx channels remain unknown. The latter, however, are widely expressed in human tissues and variation might have important implications on channel function. Investigating properties of heteromeric Cx channels is challenging considering the high number of potential subunit arrangements and stoichiometries, even when only combining two Cx isoforms. To tackle this problem, we engineered an HA tag onto Cx26 or Cx30 subunits and imaged hemichannels that were liganded by Fab-epitope antibody fragments via atomic force microscopy. For Cx26-HA/Cx30 or Cx30-HA/Cx26 heteromeric channels, the Fab-HA binding distribution was binomial with a maximum of three Fab-HA bound. Furthermore, imaged Cx26/Cx30-HA triple liganded by Fab-HA showed multiple arrangements that can be derived from the law of total probabilities. Atomic force microscopy imaging of ringlike structures of Cx26/Cx30-HA hemichannels confirmed these findings and also detected a polydisperse distribution of stoichiometries. Our results indicate a dominant subunit stoichiometry of 3Cx26:3Cx30 with the most abundant subunit arrangement of Cx26-Cx26-Cx30-Cx26-Cx30-Cx30. To our knowledge, this is the first time that the molecular architecture of heteromeric Cx channels has been revealed, thus providing the basis to explore the functional effect of these channels in biology.

rom Identification and biochemical characterization of Asp t 36, a new fungal allergen from Aspergillus terreus [Protein Structure and Folding] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Aspergillus terreus is an allergenic fungus, in addition to causing infections in both humans and plants. However, the allergens in this fungus are still unknown, limiting the development of diagnostic and therapeutic strategies. We used a proteomic approach to search for allergens, identifying 16 allergens based on two-dimensional immunoblotting with A. terreus susceptible patient sera. We further characterized triose-phosphate isomerase (Asp t 36), one of the dominant IgE (IgE)-reactive proteins. The gene was cloned and expressed in Escherichia coli. Phylogenetic analysis showed Asp t 36 to be highly conserved with close similarity to the triose-phosphate isomerase protein sequence from Dermatophagoides farinae, an allergenic dust mite. We identified four immunodominant epitopes using synthetic peptides, and mapped them on a homology-based model of the tertiary structure of Asp t 36. Among these, two were found to create a continuous surface patch on the 3D structure, rendering it an IgE-binding hotspot. Biophysical analysis indicated that Asp t 36 shows similar secondary structure content and temperature sensitivity with other reported triose-phosphate isomerase allergens. In vivo studies using a murine model displayed that the recombinant Asp t 36 was able to stimulate airway inflammation, as demonstrated by an influx of eosinophils, goblet cell hyperplasia, elevated serum Igs, and induction of Th2 cytokines. Collectively, our results reveal the immunogenic property of Asp t 36, a major allergen from A. terreus, and define a new fungal allergen more broadly. This allergen could serve as a potent candidate for investigating component resolved diagnosis and immunotherapy. Full Article
rom Evolving the naturally compromised chorismate mutase from Mycobacterium tuberculosis to top performance [Protein Structure and Folding] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Chorismate mutase (CM), an essential enzyme at the branch-point of the shikimate pathway, is required for the biosynthesis of phenylalanine and tyrosine in bacteria, archaea, plants, and fungi. MtCM, the CM from Mycobacterium tuberculosis, has less than 1% of the catalytic efficiency of a typical natural CM and requires complex formation with 3-deoxy-d-arabino-heptulosonate 7-phosphate synthase for high activity. To explore the full potential of MtCM for catalyzing its native reaction, we applied diverse iterative cycles of mutagenesis and selection, thereby raising kcat/Km 270-fold to 5 × 105 m−1s−1, which is even higher than for the complex. Moreover, the evolutionarily optimized autonomous MtCM, which had 11 of its 90 amino acids exchanged, was stabilized compared with its progenitor, as indicated by a 9 °C increase in melting temperature. The 1.5 Å crystal structure of the top-evolved MtCM variant reveals the molecular underpinnings of this activity boost. Some acquired residues (e.g. Pro52 and Asp55) are conserved in naturally efficient CMs, but most of them lie beyond the active site. Our evolutionary trajectories reached a plateau at the level of the best natural enzymes, suggesting that we have exhausted the potential of MtCM. Taken together, these findings show that the scaffold of MtCM, which naturally evolved for mediocrity to enable inter-enzyme allosteric regulation of the shikimate pathway, is inherently capable of high activity.

rom Unique active-site and subsite features in the arabinogalactan-degrading GH43 exo-{beta}-1,3-galactanase from Phanerochaete chrysosporium [Enzymology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Arabinogalactan proteins (AGPs) are plant proteoglycans with functions in growth and development. However, these functions are largely unexplored, mainly because of the complexity of the sugar moieties. These carbohydrate sequences are generally analyzed with the aid of glycoside hydrolases. The exo-β-1,3-galactanase is a glycoside hydrolase from the basidiomycete Phanerochaete chrysosporium (Pc1,3Gal43A), which specifically cleaves AGPs. However, its structure is not known in relation to its mechanism bypassing side chains. In this study, we solved the apo and liganded structures of Pc1,3Gal43A, which reveal a glycoside hydrolase family 43 subfamily 24 (GH43_sub24) catalytic domain together with a carbohydrate-binding module family 35 (CBM35) binding domain. GH43_sub24 is known to lack the catalytic base Asp conserved among other GH43 subfamilies. Our structure in combination with kinetic analyses reveals that the tautomerized imidic acid group of Gln263 serves as the catalytic base residue instead. Pc1,3Gal43A has three subsites that continue from the bottom of the catalytic pocket to the solvent. Subsite −1 contains a space that can accommodate the C-6 methylol of Gal, enabling the enzyme to bypass the β-1,6–linked galactan side chains of AGPs. Furthermore, the galactan-binding domain in CBM35 has a different ligand interaction mechanism from other sugar-binding CBM35s, including those that bind galactomannan. Specifically, we noted a Gly → Trp substitution, which affects pyranose stacking, and an Asp → Asn substitution in the binding pocket, which recognizes β-linked rather than α-linked Gal residues. These findings should facilitate further structural analysis of AGPs and may also be helpful in engineering designer enzymes for efficient biomass utilization. Full Article
rom Domestic Violence in Ukraine: Lessons from COVID-19 By www.chathamhouse.org Published On :: Thu, 23 Jul 2020 13:45:42 +0000 23 July 2020 Kateryna Busol Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme @KaterynaBusol LinkedIn The pandemic has shed light on domestic violence in Ukraine, mobilizing civil society to demand more nuanced policy on the issue. 2020-07-23-UkraineIWD.jpg A protester chants slogans on a megaphone during an International Women's Day protest on 8 March 2019 in Kyiv, Ukraine. Photo: Getty Images. The virus of violenceDuring quarantine, the greater economic vulnerability of Ukrainian women has locked many of them with abusive partners. The uncertainty of personal finances, health and security in confinement has exacerbated domestic violence against women, in certain cases aggravated by the perpetrator’s war-related post-traumatic stress disorder (PTSD).In pre- pandemic times, only one third of domestic violence victims, 78% of whom are women, reported the abuse. During the pandemic, the calls to domestic violence helplines increased by 50% in the Donbas war zone and by 35% in other regions of Ukraine.However, more precise estimates are hard to make. This is largely because some fractions of Ukrainian society still see domestic violence as a private family matter, which will get little assistance from the police. Also, reporting from a small confinement place permanently shared with a perpetrator during the lockdown can trigger more abuse.The COVID-19-tested legal frameworkThe spike in domestic violence during lockdown has intensified the debate about the inadequacy of Ukraine’s approach.Ukraine adopted the law on domestic violence in 2017 and made such behaviour punishable under administrative and criminal law. Importantly, the law does not limit domestic violence to physical abuse, but recognizes its sexual, psychological and economic variations. Domestic violence is further not limited to a married couple or close family members, but can be perpetrated against a distant relative or a cohabiting partner.The extended definition of rape now includes rape of a spouse or a family member as an aggravating circumstance. A special police unit has been designated to deal with domestic abuse cases. Police can now issue protection orders in prompt reaction to an offence and immediately distance a perpetrator from a victim.The victim can also spend time in a shelter - a system which the Ukrainian government has promised to create. A special registry of domestic violence cases has been set up for the exclusive use by the designated law enforcement and social security authorities to help them be more holistically informed in building a response.However important, the introduced legal and institutional infrastructure was slow in proving its efficiency pre-COVID-19. It is struggling even more to stand the test of the coronavirus.Changing the established mindset takes time. 38% of Ukraine’s judges and 39% of prosecutors still struggle to see domestic violence not as a household issue. Even though the police are becoming more reactive to home abuse complaints, getting emergency protection orders is still difficult. The court restraining orders are more effective, however they require the unnecessarily protracted and humiliating procedures of proving one’s own victimhood to different state authorities.In response to the challenges of coronavirus for women, the police spread information posters and created a special chat-bot about the available help. However, while the domestic violence helplines of La Strada and other human rights NGOs are busier than ever, the police statistics suggest that the lockdown has not catalyzed home abuse.This could indicate a higher trust to non-state institutions and the inability of a considerable group of women to use more sophisticated communication means such as chat-bots when they cannot call the police in the presence of an abuser. This problem is exacerbated by a current lack of shelters in rural areas, as most are located in urban settings. Overcrowded in ordinary times, the shelters’ capacity to accept survivors during the lockdown is further limited by the social distancing rules.Istanbul Convention – The bigger pictureUkraine failed to ratify the Council of Europe Convention on preventing and combating violence against women, better known as the Istanbul Convention, largely due to the opposition of religious organizations. Concerned that the treaty’s terms ‘gender’ and ‘sexual orientation’ would contribute to the promotion of same-sex relationships in Ukraine, they argued that Ukraine’s current legislation provides adequate protection against domestic violence. However, this is not the case.The Istanbul Convention does not ‘promote’ same-sex relationships, it only mentions sexual orientation among the non-exhaustive list of prohibited discrimination grounds. Remarkably, Ukraine’s domestic violence law itself is against such discrimination.The Convention defines ‘gender’ as the socially constructed roles a society attributes to women and men. Ukraine’s overcautiousness about the term is ironic at least in two dimensions.First, the 2017 domestic violence law restates its aim to eliminate discriminating beliefs about the social roles of each ‘sex’. In doing so, the law supports the rationale of what the Istanbul Convention denotes as ‘gender’ without using the term itself.Second, it is exactly the constraints of the rigidly defined niches for both sexes in Ukraine that have substantially contributed to the intensified domestic violence, whether it be war or coronavirus-related. The lack of sustainable psychological support for traumatized veterans and the stigma of mental health struggles, especially among men, mars their reintegration to peaceful life. This often results in alcohol abuse or even suicide.As the economic uncertainty of the war and the virus prevents some men from fully living up to their traditional socially - and self-imposed - breadwinner role, this increases the risk of problematic behaviour and domestic violence.By diverting the focus of the debate to the term ‘gender’ used in the Istanbul Convention, conservative groups have ignored the fact that it describes the priority already enshrined in Ukraine’s 2017 law - to eliminate discriminatory beliefs about the socially constructed roles of men and women. This has drawn away time and resources needed to protect those vulnerable to domestic abuse.Ukraine has not addressed the pigeonholing of women and men into gendered stereotypes. This has harmed men while further victimizing women and children, especially during the lockdown. Ironically, this is leading to the undermining of the very traditional family values certain opponents of the Istanbul Convention appealed to.Fortunately, Ukraine’s ever-vigilant civil society, dismayed at the wave of the lockdown domestic violence, petitioned President Zelenskyy to ratify the Convention. With a new draft law on ratification, the ball is now in the parliament’s court. It remains to be seen whether Ukraine’s policymakers will be up to the task. Full Article
rom Lessons from COVID-19: A Catalyst for Improving Sanctions? By www.chathamhouse.org Published On :: Tue, 25 Aug 2020 23:00:00 +0000 26 August 2020 Emanuela-Chiara Gillard Associate Fellow, International Law Programme As the COVID-19 pandemic continues, efforts by states and humanitarian actors to stop its spread and to treat the sick are being hindered by existing sanctions and counterterrorism measures. 2020-08-25-covid-sanctions.jpg Syrians walk past a mural painted as part of an awareness campaign by UNICEF and WHO, bearing instructions on protection from COVID-19, in the Kurdish-majority city of Qamishli, Syria, on 16 August 2020.

If sanctions imposed by the UN Security Council, the EU, or states unilaterally, are not sufficiently targeted, and do not include adequate safeguards for humanitarian action, they can adversely affect the very populations for whose well-being they were imposed in the first place. This is not a new concern, but one brought starkly to the fore by their impact on responses to COVID-19.The detrimental impact of sanctions, which can prevent the supply of medical or personal protective equipment (PPE), or the provision of technical support or training to local health authorities is evident. Sanctions can also affect remote learning if support cannot be provided to local education authorities, export licences cannot be obtained for the necessary equipment and software, or if the companies providing reliable internet coverage are designated under the sanctions.A comparison of US and EU sanctions on Syria reveals key challenges, but also opportunities for improving current arrangements for the imposition and implementation of sanctions so as to minimize adverse consequences in Syria and more generally.The US has imposed broad sanctions, such as restrictions on the provision of funds, goods or services – even charitable contributions – to the Syrian government, including the health and education ministries, now playing a central role in the COVID-19 response.UN agencies are exempted from these restrictions. A general license authorizes NGOs to conduct activities to meet basic needs, but it excludes those involving the government. So NGOs wishing to provide medical devices, PPE, training or other support to ministry of health staff have to apply for a specific licence.But procedures for applying for licences are complicated, and the approval process notoriously slow. No accommodation has been made to facilitate the COVID-19 response: no interpretative guidance – that would be valuable for all NGOs – has been issued, and no procedures established for reviewing applications more quickly. There is no statement of policy indicating the circumstances under which specific licences might be granted.Transactions with designated entities other than the government, such as internet providers whose services are necessary for remote learning, remain prohibited, and regulations expressly preclude applying for specific licences.US sanctions frequently have a broad scope, both in direct and indirect application. NGOs registered in the US, and staff who are US nationals, are directly bound by them, and grant agreements between the US government and non-US NGOs require the latter to comply with US sanctions.This leaves the non-US NGOs in a Catch-22 situation – as they are not ‘US persons’ they cannot apply for specific licenses, but if they operate without such licences they may be violating grant requirements. This lack of clarity contributes to banks’ unwillingness to provide services, and may lead NGOs to curtail their activities. This situation is regrettable in Syria, where the US is the first donor to humanitarian action, and also arises in other contexts where the US has imposed similar sanctions.The EU’s sanctions for Syria are far more targeted. Of relevance to the COVID-19 response, they do not include prohibitions on the provision of support to the government that could impede assistance in the medical field. There are, however, restrictions on the provision of certain types of PPE or substances used for disinfection, and also on transactions with designated telecommunications providers that affect continuity of education during lockdowns. Although not prohibited, these activities must be authorized by member states’ competent authorities. Similar concerns arise about the complexity and delays of the processes.The EU sanctions framework is complex, so the recent European Commission Guidance Note on Syria providing official clarification of how it applies to humanitarian action is welcome. Although the note only explains the existing rules rather than amending them to facilitate the COVID-19 response, it does include a number of important elements relevant not just to Syria, but to the interplay between sanctions and humanitarian action more broadly.First, it notes that ‘in accordance with International Humanitarian Law where no other option is available, the provision of humanitarian aid should not be prevented by EU restrictive measures’. This recognizes that humanitarian assistance takes priority over any inconsistent restrictions in sanctions, and it also applies both to UN sanctions and unilateral measures. It is a starting premise that is frequently overlooked in discussions of whether sanctions should include exceptions for humanitarian action. Its reaffirmation is timely, and it must guide states in drawing up future sanctions.Second, the note states that sanctions do not require the screening of final beneficiaries of humanitarian programmes. This means that once someone has been identified as an individual in need on the basis of humanitarian principles, no further screening is required. This is extremely important to COVID-19 responses as it reflects a foundational principle of IHL that, to the fullest extent practicable, everyone is entitled to the medical care required by their condition without distinction.Third, while responsibility for the implementation of sanctions, including the granting of authorizations, lies with member states, the note nudges them to adopt a number of measures to expedite and streamline such processes. These include the suggestion that states could issue a single authorization for the provision of humanitarian aid in response to the pandemic.The European Commission is to be commended for this initiative, which should be replicated for other contexts where the COVID-19 response may be undermined by sanctions. These include Gaza, where it would be important to highlight that the designation of Hamas under EU counterterrorism sanctions must not prevent the provision of assistance to relevant ministries.Failing to draw a distinction between the designated political party and the structures of civil administration risks turning targeted financial sanctions into measures akin to comprehensive sanctions.The pandemic should serve as a catalyst for improving the system for the adoption and implementation of sanctions by the UN, the EU and individual states, including the UK as it elaborates its sanctions policy post-Brexit. The principles are clear: without prejudicing the aims for which sanctions have been imposed, humanitarian needs must always be prioritized, and met. Full Article
rom Inhibition of mitochondrial oxidative metabolism attenuates EMCV replication and protects {beta}-cells from virally mediated lysis [Immunology] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 Viral infection is one environmental factor that may contribute to the initiation of pancreatic β-cell destruction during the development of autoimmune diabetes. Picornaviruses, such as encephalomyocarditis virus (EMCV), induce a pro-inflammatory response in islets leading to local production of cytokines, such as IL-1, by resident islet leukocytes. Furthermore, IL-1 is known to stimulate β-cell expression of iNOS and production of the free radical nitric oxide. The purpose of this study was to determine whether nitric oxide contributes to the β-cell response to viral infection. We show that nitric oxide protects β-cells against virally mediated lysis by limiting EMCV replication. This protection requires low micromolar, or iNOS-derived, levels of nitric oxide. At these concentrations nitric oxide inhibits the Krebs enzyme aconitase and complex IV of the electron transport chain. Like nitric oxide, pharmacological inhibition of mitochondrial oxidative metabolism attenuates EMCV-mediated β-cell lysis by inhibiting viral replication. These findings provide novel evidence that cytokine signaling in β-cells functions to limit viral replication and subsequent β-cell lysis by attenuating mitochondrial oxidative metabolism in a nitric oxide–dependent manner.

rom Climate migration: Ways ahead from the next generation By www.chathamhouse.org Published On :: Wed, 25 May 2022 10:05:22 +0000 Climate migration: Ways ahead from the next generation The World Today rsoppelsa.drupal 25 May 2022 Ella Dennis and Mike Higgins talk to young activists seeking solutions as global warming wreaks havoc in sub-Saharan Africa Africa has the lowest carbon emissions per capita yet the highest rate of temperature increase in the world. Rising levels of desertification, drought and flooding are already forcing millions of Africans to relocate to find more stable livelihoods. The continent’s youth will bear the brunt of this climate migration problem. It is estimated that by 2050, Africa will be home to 86 million internal climate migrants. How is climate migration already affecting sub-Saharan Africa and what frameworks could tackle it? To begin to answer those questions, five young activists from across the region, who are members of Chatham House’s Common Futures Conversations, took part in a panel discussion at the world’s first youth-led Conference on Climate Migration, convened in April by the Alliance for Citizen Engagement, a nonpartisan think tank based in the US. [Farmer-herder] conflicts will pose even larger security concerns as climate migration intensifies Laura Mukhwana, Kenyan PhD candidate The conversation and follow-up discussions focused on a common problem – climate migration brings people into conflict and puts pressure on infrastructure. In Kenya, droughts have left 3.5 million people hungry and the chronic flooding of several lakes in the Rift Valley has displaced hundreds of thousands, said Gerald Muchiri, 29, a social scientist from Kenya. One result has been outbreaks of violence between pastoralists such as the Orma people and the farmers of the Pokomo community, said Laura Mukhwana, 33, a PhD student in Kenya. She believes this violence is likely to worsen. ‘Inter-group conflicts will pose even larger security concerns for surrounding communities as climate migration intensifies,’ she said. Suleman Nuhu, 24, a farmer and veterinary student from Nigeria, said farmer-herder conflicts were his country’s most significant climate-migration issue. The movement of nomadic tribes from the north had affected him personally: ‘Nomads have trespassed on [my family’s] farms many times while moving with their livestock, destroying our crops.’ Changes in climate also force people to move from rural to urban areas. Nigeria, for instance, struggles with the so-called ‘Lagos problem’, said Temiloluwa Lawal, 25, a lawyer and researcher from Nigeria. An estimated 22 million people, a number that is rising fast, are crammed into a city smaller than Greater London. While not on the same scale, Zimbabwe experiences comparable challenges, said Tinotenda Dube, 29, a Zimbabwean finance director. Thanks to drought, unemployed rural migrants arriving in cities ‘put excessive pressure on service delivery against a low tax base,’ he said. ‘People, including close family members of mine, are crowded in dilapidated homes because they cannot afford to pay rent for decent housing.’ But there is hope, say the activists. Dube believes that affordable housing is an ‘integral component of [tackling] the climate migration crisis’. In Zimbabwe, he has developed a low-cost home finance model that, he said, has helped more than 250 low-income households find good-quality accommodation. Alongside this initiative, Dube has co-founded a property and construction company, Solinfra Zimbabwe Private Ltd, to provide low-cost housing. Muchiri is taking action in Kenya, founding an NGO called Social Assistance Welfare to tackle public health issues, he said: ‘As climate migration becomes more intense, I expect preventable health issues to increase throughout the region, and thus see Social Assistance Welfare as an important mitigation.’ To mitigate food security problems, we must reduce reliance on rain-fed agriculture through irrigation schemes Suleman Nuhu, farmer and veterinary student from Nigeria In Nigeria, Nuhu noted that to help reduce conflict between farmers and herders social-media campaigns are encouraging pastoralists to move from nomadic livestock farming to more efficient intensive systems, using ranching and grazing reserves. ‘As for food security problems, the best mitigation is to reduce reliance on rain-fed agriculture through irrigation schemes,’ he said. All five agreed that, in their experience, the youth of sub-Saharan Africa could be better informed about climate migration. But they took encouragement from the fact the young are passionate about tackling issues arising from the broader climate crisis. In Kenya, Mukhwana pointed to successful youth projects around agro-forestry and tree-planting. She added that there is ‘a growing movement of urban youth who are advocating for climate justice, such as the Kenyan Youth Environmental Network and Fridays for the Future Kenya’. It was pleasing too, she said, that when the Kenyan government revised its contributions to the Paris Climate Accords it staged a week-long youth conference to include their opinions. ‘Overall, I am quite hopeful about how the youth are mobilizing themselves in Kenya,’ she added.

rom Culture notes: Europe's broken promises to Africa By www.chathamhouse.org Published On :: Mon, 01 Aug 2022 10:28:31 +0000 Culture notes: Europe's broken promises to Africa The World Today mhiggins.drupal 1 August 2022 Europe’s ‘gas grab’ in Africa is just the latest abuse of its relationship with the continent, says Catherine Fieschi. When Emmanuel Macron made one of his first visits to Africa as France’s recently elected young president in 2017, his speech at Ouagadougou University in Burkina Faso was designed to set the tone for a new relationship between his country and African countries. ‘There no longer is a French policy for Africa,’ he said. This was a signal away from ‘la Françafrique’, with its post-colonial accents and the propping up of regimes friendly to France, to something that was more strategic, equitable and transparent – more partnership and less tutelage. And Europe seemed to be following suit. In March 2020 the European Union and Africa decided that they would redefine their relationship. The European Commission unveiled its vision for a ‘comprehensive strategy with Africa’. The roadmap would give Africa significantly more say over the nature and extent of the relationship, more choice and more political agency. Despite repeated statements, Europe seems to be saying one thing and doing another when it comes to Africa But what, today, is left of these aspirations? Despite repeated statements, Europe seems to be saying one thing and doing another. Earlier this year, after the long-awaited 6th annual EU-African Union summit in Brussels, South African president Cyril Ramaphosa was frank when he summed up the gap between stated ambitions and the current relationship. The pandemic-weary Global South had reason to be wary. Ramaphosa laid out missed opportunities, disappointment and the low expectations that act as self-fulfilling prophecies. Europe’s changing focus in Africa From the apparent high point of the Ouagadougou speech, Macron has now turned to the Organization Internationale de la Francophonie (OIF) in Africa for geopolitical purposes. His primary aim is to combat the rise of Islamist militants and terrorism in the Sahel as well as to tackle the growing influence of China and Russia in the region. Russian inroads – via the security firm Wagner in Mali, for instance – have given France further cause to use the OIF to counter destabilization activities. Both the United Kingdom and France train African military in the Sahel, but now, with the end of France’s anti-insurgent Operation Barkhane in Mali, the subsequent withdrawal of French troops and the increasingly established presence of the Wagner group, the security situation in the region is expected to deteriorate dramatically and become increasingly impermeable to European interests and forces. As for development aid, Britain’s Integrated Review of Security, Defence, Development and Foreign Policy makes no bones about the fact that Asia is now a priority over Africa. The relationship between Africa and Britain is being transformed as a result, most obviously through the cuts in development aid, with African aid cut by 66 per cent in 2021. But the nature of the relationship, which has become both more conditional and more transactional, has also changed. The UK is emphasizing human rights and ‘free societies’, but also pushing for free market principles rather than the kind of state involvement that some African countries often prefer as a road to accelerated and more autonomous development. The future of energy exports and COP27 The issue of energy exports points to what will most likely trigger the greatest disappointment in the next few years – climate and climate finance. Green energy deals, like the $8.5 billion COP26 package from the EU, United States and UK to South Africa, look far more problematic now in the light of Europe’s African gas-grab. Indeed, Europe is importing as much African gas as it can after the invasion of Ukraine by Russia reduced supplies. Yet African countries are still being told to curb their own use of ‘dirty’ energy. As an illustration, Nigeria holds 3 per cent of the world’s gas reserves, but has barely tapped them, while 40 per cent of its output is exported to Europe. In April, Italy closed deals to buy gas from Angola and the Republic of Congo, while Germany did the same with Senegal. At COP15 in Copenhagen in 2009, developed countries pledged an annual $100 billion in climate finance to developing countries for both adaptation and mitigation. But pledges have never really materialized. The aid agency Oxfam estimates that only about a third of the money has been delivered. Climate finance was again the main focus of COP26 – and dismissed by Greta Thunberg as more ‘blah, blah, blah’. This series of repeated resets, pledges and disappointments tells a story – indeed, several stories. First and foremost, it is one of arrogance and betrayal. That much is obvious. But it is also a story about stories – about how the narratives elaborated by various European countries and leaders never amount to more than a sum of transactions. Climate change places Europe, and other rich nations, at a crossroads in its relationship with Africa: the former holds the wealth, but also some of the keys and threats to the transition. COP27, to be held in Egypt in November, will be the next chapter in the story. Full Article
