Palestinians say Israel targeting prisoners' bank accounts

Palestinian officials said Friday that Israel is forcing banks in the occupied West Bank to close accounts held by the families of prisoners in Israeli jails to prevent the Palestinian Authority from providing stipends to them. Israel has long objected to the Palestinian Authority's payments to the families of prisoners and those killed in the conflict, including militants, saying it rewards terrorism. The Palestinians view the payments as a social safety net for those living under decades of military occupation.

Ukraine must drain corruption swamp, Saakashvili says in latest comeback

Mikheil Saakashvili, the former president of Georgia, vowed on Friday to help his new boss, Ukrainian President Volodymyr Zelenskiy, clean out a political "swamp" of oligarchs' interests that he said were preventing Ukraine prospering. Twice president of Georgia, Saakashvili had a brief but stormy spell in Ukrainian politics five years ago under Zelenskiy's predecessor Petro Poroshenko in which he once clambered onto a roof to avoid law enforcement.

Glucocerebrosidases catalyze a transgalactosylation reaction that yields a newly-identified brain sterol metabolite, galactosylated cholesterol [Glycobiology and Extracellular Matrices]

β-Glucocerebrosidase (GBA) hydrolyzes glucosylceramide (GlcCer) to generate ceramide. Previously, we demonstrated that lysosomal GBA1 and nonlysosomal GBA2 possess not only GlcCer hydrolase activity, but also transglucosylation activity to transfer the glucose residue from GlcCer to cholesterol to form β-cholesterylglucoside (β-GlcChol) in vitro. β-GlcChol is a member of sterylglycosides present in diverse species. How GBA1 and GBA2 mediate β-GlcChol metabolism in the brain is unknown. Here, we purified and characterized sterylglycosides from rodent and fish brains. Although glucose is thought to be the sole carbohydrate component of sterylglycosides in vertebrates, structural analysis of rat brain sterylglycosides revealed the presence of galactosylated cholesterol (β-GalChol), in addition to β-GlcChol. Analyses of brain tissues from GBA2-deficient mice and GBA1- and/or GBA2-deficient Japanese rice fish (Oryzias latipes) revealed that GBA1 and GBA2 are responsible for β-GlcChol degradation and formation, respectively, and that both GBA1 and GBA2 are responsible for β-GalChol formation. Liquid chromatography–tandem MS revealed that β-GlcChol and β-GalChol are present throughout development from embryo to adult in the mouse brain. We found that β-GalChol expression depends on galactosylceramide (GalCer), and developmental onset of β-GalChol biosynthesis appeared to be during myelination. We also found that β-GlcChol and β-GalChol are secreted from neurons and glial cells in association with exosomes. In vitro enzyme assays confirmed that GBA1 and GBA2 have transgalactosylation activity to transfer the galactose residue from GalCer to cholesterol to form β-GalChol. This is the first report of the existence of β-GalChol in vertebrates and how β-GlcChol and β-GalChol are formed in the brain.

AIG1 and ADTRP are endogenous hydrolases of fatty acid esters of hydroxy fatty acids (FAHFAs) in mice [Metabolism]

Fatty acid esters of hydroxy fatty acids (FAHFAs) are a newly discovered class of signaling lipids with anti-inflammatory and anti-diabetic properties. However, the endogenous regulation of FAHFAs remains a pressing but unanswered question. Here, using MS-based FAHFA hydrolysis assays, LC-MS–based lipidomics analyses, and activity-based protein profiling, we found that androgen-induced gene 1 (AIG1) and androgen-dependent TFPI-regulating protein (ADTRP), two threonine hydrolases, control FAHFA levels in vivo in both genetic and pharmacologic mouse models. Tissues from mice lacking ADTRP (Adtrp-KO), or both AIG1 and ADTRP (DKO) had higher concentrations of FAHFAs particularly isomers with the ester bond at the 9th carbon due to decreased FAHFA hydrolysis activity. The levels of other lipid classes were unaltered indicating that AIG1 and ADTRP specifically hydrolyze FAHFAs. Complementing these genetic studies, we also identified a dual AIG1/ADTRP inhibitor, ABD-110207, which is active in vivo. Acute treatment of WT mice with ABD-110207 resulted in elevated FAHFA levels, further supporting the notion that AIG1 and ADTRP activity control endogenous FAHFA levels. However, loss of AIG1/ADTRP did not mimic the changes associated with pharmacologically administered FAHFAs on extent of upregulation of FAHFA levels, glucose tolerance, or insulin sensitivity in mice, indicating that therapeutic strategies should weigh more on FAHFA administration. Together, these findings identify AIG1 and ADTRP as the first endogenous FAHFA hydrolases identified and provide critical genetic and chemical tools for further characterization of these enzymes and endogenous FAHFAs to unravel their physiological functions and roles in health and disease.

The testis-specific LINC component SUN3 is essential for sperm head shaping during mouse spermiogenesis [Cell Biology]

Sperm head shaping is a key event in spermiogenesis and is tightly controlled via the acrosome–manchette network. Linker of nucleoskeleton and cytoskeleton (LINC) complexes consist of Sad1 and UNC84 domain–containing (SUN) and Klarsicht/ANC-1/Syne-1 homology (KASH) domain proteins and form conserved nuclear envelope bridges implicated in transducing mechanical forces from the manchette to sculpt sperm nuclei into a hook-like shape. However, the role of LINC complexes in sperm head shaping is still poorly understood. Here we assessed the role of SUN3, a testis-specific LINC component harboring a conserved SUN domain, in spermiogenesis. We show that CRISPR/Cas9-generated Sun3 knockout male mice are infertile, displaying drastically reduced sperm counts and a globozoospermia-like phenotype, including a missing, mislocalized, or fragmented acrosome, as well as multiple defects in sperm flagella. Further examination revealed that the sperm head abnormalities are apparent at step 9 and that the sperm nuclei fail to elongate because of the absence of manchette microtubules and perinuclear rings. These observations indicate that Sun3 deletion likely impairs the ability of the LINC complex to transduce the cytoskeletal force to the nuclear envelope, required for sperm head elongation. We also found that SUN3 interacts with SUN4 in mouse testes and that the level of SUN4 proteins is drastically reduced in Sun3-null mice. Altogether, our results indicate that SUN3 is essential for sperm head shaping and male fertility, providing molecular clues regarding the underlying pathology of the globozoospermia-like phenotype.

The Destabilizing Danger of Cyberattacks on Missile Systems

2 July 2019

Dr Patricia Lewis

Research Director, Conflict, Science & Transformation; Director, International Security Programme

Dr Beyza Unal

Senior Research Fellow, International Security Programme
‘Left-of-launch’ attacks that aim to disable enemy missile systems may increase the chance of them being used, not least because the systems are so vulnerable.

2019-07-02-NKMissile.jpg

After President Trump decided to halt a missile attack on Iran in response to the downing of a US drone, it was revealed that the US had conducted cyberattacks on Iranian weapons systems to prevent Iran launching missiles against US assets in the region.

This ‘left-of-launch’ strategy – the pre-emptive action to prevent an adversary launch missiles – has been part of the US missile defence strategy for some time now. President George W Bush asked the US military and intelligence community to infiltrate the supply chain of North Korean missiles. It was claimed that the US hacked the North Korean ballistic missile programme, causing a failed ballistic missile test, in 2012.

It was not clear then – or now – whether these ‘left-of-launch’ cyberattacks aimed at North Korea were successful as described or whether they were primarily a bluff. But that is somewhat irrelevant; the belief in the possibility and the understanding of the potential impact of such cyber capabilities undermines North Korean or Iranian confidence in their abilities to launch their missiles. In times of conflict, loss of confidence in weapons systems may lead to escalation.

In other words, the adversary may be left with no option but to take the chance to use these missiles or to lose them in a conflict setting. ‘Left of launch’ is a dangerous game. If it is based on a bluff, it could be called upon and lead to deterrence failure. If it is based on real action, then it could create an asymmetrical power struggle. If the attacker establishes false confidence in the power of a cyber weapon, then it might lead to false signalling and messaging.

This is the new normal. The cat-and-mouse game has to be taken seriously, not least because missile systems are so vulnerable.

There are several ways an offensive cyber operation against missile systems might work. These include exploiting missile designs, altering software or hardware, or creating clandestine pathways to the missile command and control systems.

They can also be attacked in space, targeting space assets and their link to strategic systems.

Most missile systems rely, at least in part, on digital information that comes from or via space-based or space-dependent assets such as: communication satellites; satellites that provide position, navigation and timing (PNT) information (for example GPS or Galileo); weather satellites to help predict flight paths, accurate targeting and launch conditions; and remote imagery satellites to assist with information and intelligence for the planning and targeting.

Missile launches themselves depend on 1) the command and control systems of the missiles, 2) the way in which information is transmitted to the missile launch facilities and 3) the way in which information is transmitted to the missiles themselves in flight. All these aspects rely on space technology.

In addition, the ground stations that transmit and receive data to and from satellites are also vulnerable to cyberattack – either through their known and unknown internet connectivity or through malicious use of flash drives that contain a deliberate cyber infection.

Non-space-based communications systems that use cable and ground-to-air-to-ground masts are likewise under threat from cyberattacks that find their way in via internet connectivity, proximity interference or memory sticks. Human error in introducing connectivity via phones, laptops and external drives, and in clicking on malicious links in sophisticated phishing lures, is common in facilitating inadvertent connectivity and malware infection.

All of these can create a military capacity able to interfere with missile launches. Malware might have been sitting on the missile command and control system for months or even years, remaining inactivated until a chosen time or by a trigger that sets in motion a disruption either to the launch or to the flight path of the missile. The country that launches the missile that either fails to launch or fails to reach the target may never know if this was the result of a design flaw, a common malfunction or a deliberate cyberattack.

States with these capabilities must exercise caution: cyber offence manoeuvres may prevent the launch of missile attacks against US assets in the Middle East or in the Pacific regions, but they may also interfere with US missile launches in the future. Even, as has recently been revealed, US cyber weapons targeting an adversary may blow back and inadvertently infect US systems. Nobody is invulnerable.

Since the overthrow of the regime of Muammar Gaddafi in 2011, Libya’s multitude of armed groups have followed a range of paths. While many of these have gradually demobilized, others have remained active, and others have expanded their influence. In the west and south of the country,  armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks.

In the east, the Libyan Arab Armed Forces projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will need to address the fears, grievances and desires of the surrounding communities, even while the development of armed groups’ capacities dilutes their accountability to those communities.

This roundtable will discuss the findings of a forthcoming Chatham House research paper, ‘The Development of Libyan Armed Groups Since 2014: Community Dynamics and Economic Interests’, which presents insights from over 200 interviews of armed actors and members of local communities and posits how international policymakers might seek to curtail the continued expansion of the conflict economy.

Summary

  • Libya’s multitude of armed groups have followed a range of paths since the emergence of a national governance split in 2014. Many have gradually demobilized, others have remained active, and others have expanded their influence. However, the evolution of the Libyan security sector in this period remains relatively understudied. Prior to 2011, Libya’s internal sovereignty – including the monopoly on force and sole agency in international relations – had been personally vested in the figure of Muammar Gaddafi. After his death, these elements of sovereignty reverted to local communities, which created armed organizations to fill that central gap. National military and intelligence institutions that were intended to protect the Libyan state have remained weak, with their coherence undermined further by the post-2014 governance crisis and ongoing conflict. As a result, the most effective armed groups have remained localized in nature; the exception is the Libyan Arab Armed Forces (LAAF), which has combined and amalgamated locally legitimate forces under a central command.
  • In the west and south of the country, the result of these trends resembles a kind of inversion of security sector reform (SSR) and disarmament, demobilization and reintegration (DDR): the armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks; and have continued to arm, mobilize and integrate themselves into the state’s security apparatus without becoming subservient to it. In the eastern region, the LAAF projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. The LAAF has co-opted social organizations to dominate political and economic decision-making.
  • The LAAF has established a monopoly over the control of heavy weapons and the flow of arms in eastern Libya, and has built alliances with armed groups in the east. Armed groups in the south have been persuaded to join the LAAF’s newly established command structure. The LAAF’s offensive on the capital, which started in April 2019, represents a serious challenge to armed groups aligned with the Tripoli-based Government of National Accord (GNA). The fallout from the war will be a challenge to the GNA or any future government, as groups taking part in the war will expect to be rewarded. SSR is thus crucial in the short term: if the GNA offers financial and technical expertise and resources, plus legal cover, to armed groups under its leadership, it will increase the incentive for armed groups to be receptive to its plans for reform.
  • Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will necessarily rely on addressing the fears, grievances and desires of the surrounding communities. Yet the development of armed groups’ capacities, along with their increasing access to autonomous means of generating revenue, has steadily diluted their accountability to local communities. This process is likely to be accelerated by the ongoing violence around Tripoli.
  • Communities’ relationship to armed groups varies across different areas of the country, reflecting the social, political, economic and security environment:
  • Despite their clear preference for a more formal, state-controlled security sector, Tripoli’s residents broadly accept the need for    the presence of armed groups to provide security. The known engagement of the capital’s four main armed groups in criminal activity is a trade-off that many residents seem able to tolerate, providing that overt violence remains low. Nonetheless, there is a widespread view that the greed of Tripoli’s armed groups has played a role in stoking the current conflict.
  • In the east, many residents appear to accept (or even welcome) the LAAF’s expansion beyond the security realm, provided that it undertakes these roles effectively. That said, such is the extent of LAAF control that opposition to the alliance comes at a high price.
  • In the south, armed groups draw heavily on social legitimacy, acting as guardians of tribal zones of influence and defenders of their respective communities against outside threats, while also at times stoking local conflicts. Social protections continue to hold sway, meaning that accountability within communities is also limited.
  • To varying extents since 2014, Libya’s armed groups have developed networks that enmesh political and business stakeholders in revenue-generation models:
  • Armed groups in Tripoli have compensated for reduced financial receipts from state budgets by cultivating unofficial and illicit sources of income. They have also focused on infiltrating state institutions to ensure access to state budgets and contracts dispersed in the capital.
  • In the east of the country, the LAAF has developed a long-term strategy to dominate the security, political and economic spheres through the establishment of a quasi-legal basis for receiving funds from Libya’s rival state authorities. It has supplemented this with extensive intervention in the private sector. External patronage supports military operations, but also helps to keep this financial system, based on unsecured debt, afloat.
  • In the south, limited access to funds from the central state has spurred armed groups to become actively involved in the economy. This has translated into the taxation of movement and the imposition of protection fees, particularly on informal (and often illicit) activity.
  • Without real commitment from international policymakers to enforcing the arms embargo and protecting the economy from being weaponized, Libya will be consigned to sustained conflict, further fragmentation and potential economic collapse. Given the likely absence of a political settlement in the short term, international policymakers should seek to curtail the continued expansion of the conflict economy by reducing armed groups’ engagement in economic life.
  • In order to reduce illicit activities, international policymakers should develop their capacity to identify and target chokepoints along illicit supply chains, with a focus on restraining activities and actors in closest proximity to violence. Targeted sanctions against rent maximizers (both armed and unarmed) is likely to be the most effective strategy. More effective investigation and restraint of conflict economy actors will require systemic efforts to improve transparency and enhance the institutional capacity of anti-corruption authorities. International policymakers should also support the development of tailored alternative livelihoods that render conflict economy activities less attractive.

In Syria, uncertainty about the safety of the ceasefire agreed between Russia and Turkey last month is inhibiting 1 million people who have been displaced since December 2019 from returning home.

The looming COVID-19 global health crisis threatens to further devastate those most vulnerable as the conditions in northwest Syria’s refugee camps make it hard to practice common social distancing guidelines. Added to this, the medical infrastructure in the region has been decimated after years of bombings which has disabled over 70 health facilities since April 2019.

This webinar highlights the potentially catastrophic risks of a coronavirus outbreak in Idlib and displacement camps in northwest Syria by speaking with medical and civil society actors working in the region. How are doctors and local humanitarian organizations scaling up their medical and prevention response to the COVID-19 outbreak?

What key supplies such as ventilators, testing kits and critical sanitary equipment are still lacking? And how can the international community step in to help mitigate the potentially devastating consequences of an outbreak in these refugee camps?

This event is run in collaboration with The Syria Campaign, a human rights organization working with Syrian civil society to raise the voices of those struggling for democracy, and support frontline activists and humanitarians.

Can Protest Movements in the MENA Region Turn COVID-19 Into an Opportunity for Change?

29 April 2020

Dr Georges Fahmi

Associate Fellow, Middle East and North Africa Programme
The COVID-19 pandemic will not in itself result in political change in the MENA region, that depends on the ability of both governments and protest movements to capitalize on this moment. After all, crises do not change the world - people do.

2020-04-28-covid-19-protest-movement-mena.jpg

COVID-19 has offered regimes in the region the opportunity to end popular protest. The squares of Algiers, Baghdad, and Beirut – all packed with protesters over the past few months – are now empty due to the pandemic, and political gatherings have also been suspended. In Algeria, Iraq and Lebanon, COVID-19 has achieved what snipers, pro-regime propaganda, and even the economic crisis, could not.

Moreover, political regimes have taken advantage of the crisis to expand their control over the political sphere by arresting their opponents, such as in Algeria where the authorities have cracked down on a number of active voices of the Hirak movement. Similarly, in Lebanon, security forces have used the pandemic as an excuse to crush sit-ins held in Martyr’s Square in Beirut and Nour Square in Tripoli.

However, despite the challenges that the pandemic has brought, it also offers opportunities for protest movements in the region. While the crisis has put an end to popular mobilization in the streets, it has  created new forms of activism in the shape of solidarity initiatives to help those affected by its consequences.

In Iraq, for example, protest groups have directed their work towards awareness-raising and sharing essential food to help mitigate the problem of food shortages and rising prices across the country. In Algeria, Hirak activists have run online campaigns to raise awareness about the virus and have encouraged people to stay at home. Others have been cleaning and disinfecting public spaces. These initiatives increase the legitimacy of the protest movement, and if coupled with political messages, could offer these movements an important chance to expand their base of popular support.

Exposes economic vulnerability

Economic grievances, corruption and poor provision of public services have been among the main concerns of this recent wave of protests. This pandemic only further exposes the levels of economic vulnerability in the region. COVID-19 is laying bare the socio-economic inequalities in MENA countries; this is particularly evident in the numbers of people engaged in the informal economy with no access to social security, including health insurance and pensions.

Informal employment, approximately calculated by the share of the labour force not contributing to social security, is estimated to amount to 65.5% of total employment in Lebanon, 64.4% in Iraq, and 63.3% in Algeria. The crisis has underscored the vulnerability of this large percentage of the labour force who have been unable to afford the economic repercussions of following state orders to stay at home.

The situation has also called attention to the vital need for efficient public services and healthcare systems. According to the fifth wave of the Arab Barometer, 74.4% of people in Lebanon are dissatisfied with their country’s healthcare services, as are 67.8% of people in Algeria and 66.5% in Iraq.

Meanwhile, 66.2% of people in Lebanon believe it is necessary to pay a bribe in order to receive better healthcare, as do 56.2% of people in Iraq and 55.9% in Algeria. The COVID-19 crisis has highlighted the need for more government investment in public healthcare systems to render them more efficient and less corrupt, strengthening the protesters’ case for the need for radical socio-economic reforms.

On the geopolitical level, the crisis puts into question the stability-focused approach of Western powers towards the region. For years, Western powers have directed their aid towards security forces in the interests of combating terrorism but COVID-19 has proved itself to be a much more lethal challenge to both the region and the West.

Facing this new challenge requires international actors to reconsider their approach to include supporting health and education initiatives, as well as freedom of expression and transparency. As argued by Western policymakers themselves, it was China’s lack of transparency and slow response that enabled the proliferation of the virus, when it could have been contained in Wuhan back in December 2019.

This crisis therefore offers regional protest movements the opportunity to capitalize on this moment and push back against the policies of Western powers that have invested in regional stability only to the extent of combating Islamic jihad. 

But crises do not change the world, people do. The COVID-19 pandemic will not in itself result in political change in the MENA region. Rather, it brings opportunities and risks that, when exploited, will allow political actors to advance their own agendas. While the crisis has put an end to popular mobilization and allowed regimes to tighten their grip over the political sphere, behind these challenges lie real opportunities for protest movements.

The current situation represents a possibility for them to expand their popular base through solidarity initiatives and has exposed more widely the importance of addressing socio-economic inequalities. Finally, it offers the chance to challenge the stability-focused approach of Western powers towards the region which until now has predominantly focused on combating terrorism.

The objective of this study was to assess the tracer biodistribution, dosimetry and quantitative methods of 18F-PI-2620 in the human brain. Full kinetic modelling approaches to quantify tau load were investigated. Non-invasive kinetic modeling approaches and semi-quantitative methods were evaluated against the full tracer kinetics. Finally, the reproducibility of PET measurements from test and retest scans was assessed. Methods: Three healthy controls (HC) and 4 Alzheimer disease (AD) subjects underwent two dynamic PET scans including arterial sampling. Distribution volume ratio (DVR) was estimated using full tracer kinetics (2 Tissue Compartment (2TC) models, Logan Graphical Analysis (LGA)) and non-invasive kinetic models (Non-Invasive Logan Graphical Analysis (NI-LGA) and the multilinear reference tissue model (MRTM2)). Standardized uptake value ratio (SUVR) was determined at different imaging windows after injection. Correlation between DVR and SUVR, effect size (Cohen’s d) and test-retest variability (TRV) were evaluated. Additionally, 6 HC subjects received one tracer administration and underwent whole-body PET for dosimetry calculation. Organ doses and the whole-body effective dose were calculated using OLINDA 2.0. Results: Strong correlation was found across different kinetic models (R2 >0.97) and between DVR(2TC) and SUVRs between 30 to 90 min with R2>0.95. Secular equilibrium was reached around 40 min post injection (p.i.) in most regions and subjects. The TRV and effect size for the SUVR across different regions was similar at 30-60 min (TRV=3.8%, d=3.80), 45-75 min (TRV=4.3%, d=3.77) and 60-90 min (TRV=4.9%, d=3.73) and increased at later time points. Elimination was via the hepatobiliary and urinary system. The whole-body effective dose was determined to be 33.3±2.1 μSv/MBq for an adult female and 33.1±1.4 μSv/MBq for an adult male with a 1.5 hour urinary bladder voiding interval. Conclusion: 18F-PI-2620 exhibits fast kinetics, suitable dosimetry and low TRV. DVR measured using the 2TC model with arterial sampling correlated strongly with DVR measured by NI-LGA, MRTM2 and SUVR. SUVR can be used for 18F-PI-2620 PET quantification of tau deposits avoiding arterial blood sampling. Static 18F-PI-2620 PET scans between 45-75min p.i. provide excellent quantification accuracy, large effect size and low TRV.

Quantitative test-retest measurement of 68Ga-PSMA-HBED-CC (PSMA-11) in tumor and normal tissue

The PET radiotracer 68Ga-PSMA-HBED-CC (68Ga-PSMA-11) shows potential as an imaging biomarker for recurrent and metastatic prostate cancer. The purpose of this study was to determine repeatability of 68Ga-PSMA-HBED-CC in a test-retest trial in subjects with metastatic prostate adenocarcinoma. Methods: Subjects with metastatic prostate cancer underwent two PET/CT scans with 68Ga-PSMA-HBED-CC within 14 days (mean 6 ± 4 d). Lesions in bone, nodes, prostate/bed, and visceral organs as well as representative normal tissues (salivary glands and spleen) were segmented separately by two readers. Absolute and percent differences in SUVmax and SUVmean were calculated for all test-retest regions. Repeatability was assessed using percentage difference, within-subject coefficient of variation (wCV), repeatability coefficient (RC), and Bland-Altman analysis. Results: 18 subjects were evaluated, 16 of which demonstrated local or metastatic disease on 68Ga-PSMA-HBED-CC PET/CT. A total of 136 lesions were segmented in bone (n = 99), nodes (n = 27), prostate/bed (n = 7), and viscera (n = 3). The wCV for SUVmax was 11.7% for bone lesions and 13.7% for nodes. The RC was ±32.5% SUVmax for bone lesions and ±37.9% SUVmax for nodal lesions, meaning 95% of the normal variability between two measurements will be within these numbers, so larger differences are likely attributable to true biological changes in tumor rather than normal physiologic or measurement variability. wCV in the salivary glands and spleen was 8.9% and 10.7% SUVmean, respectively. Conclusion: Repeatability measurements for PET/CT test-retest with 68Ga-PSMA-HBED-CC show a wCV 12-14% SUVmax and RC ±33-38% SUVmax in bone and nodal lesions. These estimates are an important aspect of 68Ga-PSMA-HBED-CC as a quantitative imaging biomarker. These estimates are similar to those reported for 18F-FDG, suggesting that 68Ga-PSMA-HBED-CC PET/CT may be useful in monitoring response to therapy.

Efficacy of Peptide Receptor Radionuclide Therapy for Esthesioneuroblastoma

Objectives: Esthesioneuroblastoma (ENB) is rare with limited therapeutic options when unresectable or metastatic; however, expression of somatostatin receptors qualifies it for peptide receptor radionuclide therapy (PRRT). We report outcomes of PRRT in ENB from two referral centers. Methods: Using PRRT databases at two European Neuroendocrine Tumour Society Centers of Excellence, case finding was undertaken between 2004-2018 for patients who had PRRT with recurrent/metastatic ENB deemed unsuitable for further conventional therapies. Evaluations of response using a composite reference standard and for survival were performed. Results: Of seven patients, four had partial response, two had disease stabilization and one had early progression. Possible side effects include worsening CSF-leaks. Median progression-free survival was 17 months (range, 0-30), and median overall survival was 32 months (range, 4–53). Conclusion: PRRT shows promising efficacy and moderate survival duration in unresectable locally advanced or metastatic ENB warranting larger cohort studies incorporating measures of quality of life.

The role of FAPI-PET/CT for patients with malignancies of the lower gastrointestinal tract - first clinical experience

For oncological management or radiotherapy planning, reliable staging tools are essential. Recent development of quinoline-based ligands targeting cancer-associated fibroblasts demonstrated promising preclinical and clinical results. The current study aimed to evaluate the role of fibroblast activation protein inhibitors (FAPI)-positron-emission tomography (PET)/computed tomography (CT) for primary malignancies located within the lower gastrointestinal tract (LGT) as a very first clinical analysis. Methods: 68Ga-FAPI-PET/CT was performed in a cohort of 22 patients with LGT including 15 patients with metastatic disease, 1 patient with suspected local relapse and 6 treatment-naïve patients. 68Ga-FAPI-04 and 68Ga-FAPI-46 uptake was quantified by standardized uptake values (SUV)max and (SUV)mean. After comparison with standard imaging, changes in tumor stage/ localization and (radio)oncological management were recorded. Results: The highest uptake of FAPI tracer was observed in liver metastases and anal cancer with a SUVmax of 9.1 and 13.9, respectively. Due to a low background activity in normal tissue, there was a high tumor-to-background ratio of more than 3 in most lesions. In treatment-naïve patients, TNM was changed in 50% while for patients with metastases new findings occurred in 47%. In total, FAPI-imaging caused a high, medium and low change of (radio)oncological management in 19%, 33% and 29%, respectively. For almost every patient undergoing irradiation, target volume delineation was improved by 68Ga-FAPI-PET/CT. Conclusion: The present study demonstrated that both primary and metastatic LGT were reliably detected by 68Ga-FAPI-PET/CT leading to relevant changes in TNM status and (radio)oncological management. 68Ga-FAPI-PET/CT seems to be a highly promising imaging agent for the diagnosis and management of LGT, potentially opening new applications for tumor (re-)staging.

Kinetic modeling and test-retest reproducibility of 11C-EKAP and 11C-FEKAP, novel agonist radiotracers for PET imaging of the kappa opioid receptor in humans

The kappa opioid receptor (KOR) is implicated in various neuropsychiatric disorders. We previously evaluated an agonist tracer, 11C-GR103545, for PET imaging of KOR in humans. Although 11C-GR103545 showed high brain uptake, good binding specificity, and selectivity to KOR, it displayed slow kinetics and relatively large test-retest variability (TRV) of distribution volume (VT) estimates (15%). Therefore we set out to develop two novel KOR agonist radiotracers, 11C-EKAP and 11C-FEKAP, and in nonhuman primates, both tracers exhibited faster kinetics and comparable binding parameters to 11C-GR103545. The aim of this study was to assess their kinetic and binding properties in humans. Methods: Six healthy subjects underwent 120-min test-retest PET scans with both 11C-EKAP and 11C-FEKAP. Metabolite-corrected arterial input functions were measured. Regional time-activity curves (TACs) were generated for 14 regions of interest. One- and two-tissue compartment models (1TC, 2TC) and the multilinear analysis-1 (MA1) method were applied to the regional TACs to calculate VT. Time-stability of VT values and test-retest reproducibility were evaluated. Levels of specific binding, as measured by the non-displaceable binding potential (BPND) for the three tracers (11C-EKAP, 11C-FEKAP and 11C-GR103545), were compared using a graphical method. Results: For both tracers, regional TACs were fitted well with the 2TC model and MA1 method (t*=20min), but not with the 1TC model. Given unreliably estimated parameters in several fits with the 2TC model and a good match between VT values from MA1 and 2TC, MA1 was chosen as the appropriate model for both tracers. Mean MA1 VT values were highest for 11C-GR103545, followed by 11C-EKAP, then 11C-FEKAP. Minimum scan time for stable VT measurement was 90 and 110min for 11C-EKAP and 11C-FEKAP, respectively, compared with 140min for 11C-GR103545. The mean absolute TRV in MA1 VT estimates was 7% and 18% for 11C-EKAP and 11C-FEKAP, respectively. BPND levels were similar for 11C-FEKAP and 11C-GR103545, but ~25% lower for 11C-EKAP. Conclusion: The two novel KOR agonist tracers showed faster tissue kinetics than 11C-GR103545. Even with slightly lower BPND, 11C-EKAP is judged to be a better tracer for imaging and quantification of KOR in humans, based on the shorter minimum scan time and excellent test-retest.

PET imaging of phosphodiesterase-4 identifies affected dysplastic bone in McCune-Albright syndrome, a genetic mosaic disorder

McCune-Albright syndrome (MAS) is a mosaic disorder arising from gain-of-function mutations in the GNAS gene, which encodes the 3', 5'-cyclic adenosine monophosphate (cAMP) pathway-associated G-protein, Gsα. Clinical manifestations of MAS in a given individual, including fibrous dysplasia, are determined by the timing and location of the GNAS mutation during embryogenesis, the tissues involved, and the role of Gsα in the affected tissues. The Gsα mutation results in dysregulation of the cAMP signaling cascade, leading to upregulation of phosphodiesterase type 4 (PDE4), which catalyzes the hydrolysis of cAMP. Increased cAMP levels have been found in vitro in both animal models of fibrous dysplasia and in cultured cells from individuals with MAS, but not in humans with fibrous dysplasia. Positron emission tomography (PET) imaging of PDE4 with 11C-(R)-rolipram has been used successfully to study the in vivo activity of the cAMP cascade. To date, it remains unknown whether fibrous dysplasia and other symptoms of MAS, including neuropsychiatric impairments, are associated with increased PDE4 activity in humans. Methods: 11C-(R)-rolipram whole-body and brain PET scans were performed in six individuals with MAS (three for brain scans and six for whole-body scans) and nine healthy controls (seven for brain scans and six for whole-body scans). Results: 11C-(R)-rolipram binding correlated with known locations of fibrous dysplasia in the periphery of individuals with MAS; no uptake was observed in the bones of healthy controls. In peripheral organs and the brain, no difference in 11C-(R)-rolipram uptake was noted between participants with MAS and healthy controls. Conclusion: This study is the first to find evidence for increased cAMP activity in areas of fibrous dysplasia in vivo. No differences in brain uptake between MAS participants and controls were detected, which could be due to several reasons, including the limited anatomic resolution of PET. Nevertheless, the results confirm the usefulness of PET scans with 11C-(R)-rolipram to indirectly measure increased cAMP pathway activation in human disease.

Central and Eastern Europe and Sub-Saharan Africa: The Potential of Investment Partnerships for Mutual Benefit

31 October 2019

Trade between Central and Eastern Europe and sub-Saharan Africa has increased significantly in the last decade and a half. There is a strong case to be made for greater economic re-engagement, especially in terms of investment, that has the potential to support inclusive growth in both regions.

Summary

  • There are growing economic links between the economies of Central and Eastern Europe and sub-Saharan Africa in terms of both trade and investment. However, while trade has picked up significantly from pre-EU accession levels, investment has not increased to the same extent.
  • Contrary to common assumption, investment flows are not solely from Central and Eastern Europe to sub-Saharan Africa. In reality, the largest investment flow between the two blocs occurs in the opposite direction – from South Africa into Central and Eastern Europe.
  • Sub-Saharan Africa can benefit from a greater commercial relationship focused on attracting sustainable investment from Central and Eastern Europe. For this to happen, commercial strategies towards Central and Eastern European countries need to be put in place before strategy can be reinforced by greater diplomatic and informational support.
  • For many sub-Saharan African governments, there is no overall targeted approach to attracting Central and Eastern European investors. A notable exception is South Africa, where departments have been established at provincial government level to specifically target investment from Central and Eastern Europe.
  • Sub-Saharan African governments expect Central and Eastern European private-sector investment to result not only in job creation, but also to bring spillover benefits such as the transfer of skills and knowledge to domestic industries.
  • Each sub-Saharan African country, in accordance with its individual circumstances, will need to adopt a discrete mix of administrative reform (particularly aimed at cutting red tape), as well as infrastructural and other policies that improve the business environment and generate investor confidence.
  • Much of the private sector in Central and Eastern Europe is somewhat hesitant to invest in sub-Saharan Africa on a greater scale. Many companies are most comfortable operating within their domestic environment; when they invest abroad, it tends to be in the ‘neighbourhood’ with which they are already familiar. Perceptions of risk are often compounded by popular misperceptions and generalizations about sub-Saharan Africa.
  • Central and Eastern European countries stand to gain from a deeper investment relationship. While greater engagement with sub-Saharan Africa has already been pursued by some countries, most of them focus on trade. Institutional support to companies from Central and Eastern Europe (both public and private) has evolved to a degree, but is still not comprehensive. Information for companies interested in investing is either lacking or not shared in an efficient way. And the greatest challenge is ensuring top-level political engagement.
  • EU membership offers clear opportunities for Central and Eastern European countries to invest sustainably and responsibly in sub-Saharan Africa. Not only is financial support forthcoming, through innovative EU financial instruments, but the availability of information relevant to business and the EU’s extensive diplomatic presence in Africa should help to alleviate some of the concerns of Central and Eastern European investors.

Côte d'Ivoire’s 2020 Elections: Contestation and Change

Invitation Only Research Event

8 November 2019 - 12:00pm to 1:00pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Hon Guillaume Soro, Chairman, Rassemblement Pour la Côte d’Ivoire (RACI)
Chair: Paul Melly, Consulting Fellow, Africa Programme, Chatham House

As Côte d'Ivoire enters a critical final 12 months before presidential elections scheduled for October 2020, the political atmosphere remains highly uncertain, stoked by the fracturing of the RDR-PDCI alliance and the potential candidacy of a range of high-profile political names. While President Ouattara’s two terms in office have ushered in an improved business environment, with annual economic growth averaging 8 per cent since 2012, political instability over the next 12 months may pose a threat to recent progress and raises wider security concerns in light of the major post-election violence witnessed a decade previously.

At this event, Ivorian presidential contender, and former prime minister and parliamentary speaker, Guillaume Soro, will assess the prime-election context in Côte d'Ivoire and the policies required to deliver inclusive growth and future stability for its citizens.

Attendance at this event is by invitation only.

Chair: Dr Alex Vines OBE, Managing Director, Ethics, Risk & Resilience; Director, Africa Programme, Chatham House

Theresa May’s announcement in 2018 on the UK’s ambition to become the G7’s largest investor in Africa by 2022 has been followed by similar stated ambitions at the recent UK-Africa Investment Summit, which saw the attendance of 16 African heads of states. Such ambitions mirror overtures from various international players including a call for a ‘comprehensive strategy for Africa’ by the EU in 2019. While the UK’s recent expansion of its diplomatic networks in Africa and the signing of the Economic Partnership Agreement with the Southern African Customs Union and Mozambique appear promising, there are significant challenges to deepening partnerships including visa restrictions and complex business environments.
 
At this event, the panellists will assess the future of trade and investment relations between the UK and Africa. Amid a proliferation of new trading partners including Asia’s emerging economies, Russia and the Gulf states, what are the points of change and continuity in the long-standing relationship between Africa and the UK? And what are the challenges and opportunities facing governments and businesses in Africa and the UK in efforts to build long-lasting economic ties?
 
This event will be followed by a drinks reception.

Coronavirus Risks Worsening a Food Crisis in the Sahel and West Africa

1 May 2020

Dr Leena Koni Hoffmann

Associate Fellow, Africa Programme

Paul Melly

Consulting Fellow, Africa Programme
In responding to the spread of the coronavirus, the governments of the Sahel and West Africa will need to draw on their collective experience of strategic coordination in emergency planning, and work together to prioritize the flow of food across borders.

The COVID-19 pandemic has struck the Sahel and West Africa at a time when the region is already under severe pressure from violent insecurity and the effects of climate change on its land, food and water resources.

By the end of April, there had been 9,513 confirmed coronavirus cases across the 17 countries of the region, and some 231 deaths, with the highest overall numbers recorded in Nigeria, Ghana, Guinea, Côte d’Ivoire, Senegal, Niger and Burkina Faso. Low testing rates mean than these numbers give only a partial picture.

The Food Crisis Prevention Network (RPCA) forecast in early April that almost 17 million people in the Sahel and West Africa (7.1 million in Nigeria alone) will need food and nutritional assistance during the coming lean season in June–August, more than double the number in an average year. The combined impact of violent insecurity and COVID-19 could put more than 50 million other people across the region at risk of food and nutrition crisis.

Rippling across the region

The effects of the collapse in global commodity prices, currency depreciations, rising costs of consumer goods and disruptions to supply chains are rippling across the region. And for major oil-exporting countries such as Nigeria, Ghana, Chad and Cameroon, the wipe-out of foreign currency earnings will hammer government revenues just as the cost of food and other critical imports goes up. It is likely that the number of people who suffer the direct health impact of the coronavirus will be far outstripped by the number for whom there will be harsh social and economic costs.

In recent years, valuable protocols and capacities have been put in place by governments in West and Central Africa in response to Ebola and other infectious disease outbreaks.

But inadequate healthcare funding and infrastructure across this region compound the challenge of responding to the spread of the COVID-19 infection – which is testing the resources of even the world’s best-funded public health systems.

Over many years, however, the region has steadily built up structures to tackle humanitarian and development challenges, particularly as regards food security. It has an established system for assessing the risk of food crisis annually and coordinating emergency support to vulnerable communities. Each country monitors climate and weather patterns, transhumance, market systems and agricultural statistics, and terrorist disruption of agricultural productivity, from local community to national and regional level.

The system is coordinated and quality-controlled, using common technical data standards, by the Permanent Interstate Committee for Drought Control in the Sahel (CILSS), a regional intergovernmental body established in 1973 in response to a devastating drought. Collective risk assessments allow emergency support to be mobilized through the RPCA.

For almost three months already, countries in Sahelian West Africa have been working with the World Health Organization to prepare national COVID-19 response strategies and strengthen health controls at their borders. Almost all governments have also opted for domestic curfews, and variations of lockdown and market restrictions.

Senegal has been a leader in rapidly developing Africa’s diagnostic capacity, and plans are under way to speed up production of test kits. Niger was swift to develop a national response strategy, to which donors have pledged €194.5 million. While the IMF has agreed emergency financial assistance to help countries address the urgent balance-of-payments, health and social programme needs linked to the COVID-19 pandemic, signing off $3.4 billion for Nigeria, $442 million for Senegal and $130 million for Mauritania.

Steps are also now being taken towards the formulation of a more joined-up regional approach. Notably, Nigeria’s President Muhammadu Buhari has been chosen by an extraordinary session of the Economic Community of West African States to coordinate the regional response to COVID-19. As Africa’s biggest economy and home to its largest population, Nigeria is a critical hub for transnational flows of goods and people. Its controversial August 2019 land border closure, in a bid to address smuggling, has already painfully disrupted regional agri-food trade and value chains. The active engagement of the Buhari administration will thus be crucial to the success of a multifaceted regional response.

One of the first tough questions the region’s governments must collectively address is how long to maintain the border shutdowns that were imposed as an initial measure to curb the spread of the virus. Closed borders are detrimental to food security, and disruptive to supply chains and the livelihoods of micro, small and medium-sized entrepreneurs that rely on cross-border trade. The impact of prolonged closures will be all the more profound in a region where welfare systems are largely non-existent or, at best, highly precarious.

Nigeria, in particular, with more than 95 million people already living in extreme poverty, might do well to explore measures to avoid putting food further beyond the reach of people who are seeing their purchasing power evaporate.

In taking further actions to control the spread of the coronavirus, the region’s governments will need to show faith in the system that they have painstakingly developed to monitor and respond to the annual risk of food crisis across the Sahel. This system, and the critical data it offers, will be vital to informing interventions to strengthen the four components of food security – availability, access, stability and utilization – in the context of COVID-19, and for charting a post-pandemic path of recovery.

Above all, careful steps will need to be put in place to ensure that preventing the spread of the coronavirus does not come at the cost of even greater food insecurity for the people of the Sahel and West Africa. The region’s governments must prioritize the flow of food across borders and renew their commitment to strategic coordination and alignment.

Interaction Proteomics Identifies ERbeta Association with Chromatin Repressive Complexes to Inhibit Cholesterol Biosynthesis and Exert An Oncosuppressive Role in Triple-negative Breast Cancer [Research]

Triple-negative breast cancer (TNBC) is characterized by poor response to therapy and low overall patient survival. Recently, Estrogen Receptor beta (ERβ) has been found to be expressed in a fraction of TNBCs where, because of its oncosuppressive actions on the genome, it represents a potential therapeutic target, provided a better understanding of its actions in these tumors becomes available. To this end, the cell lines Hs 578T, MDA-MB-468 and HCC1806, representing the claudin-low, basal-like 1 and 2 TNBC molecular subtypes respectively, were engineered to express ERβ under the control of a Tetracycline-inducible promoter and used to investigate the effects of this transcription factor on gene activity. The antiproliferative effects of ERβ in these cells were confirmed by multiple functional approaches, including transcriptome profiling and global mapping of receptor binding sites in the genome, that revealed direct negative regulation by ERβ of genes, encoding for key components of cellular pathways associated to TNBC aggressiveness representing novel therapeutic targets such as angiogenesis, invasion, metastasis and cholesterol biosynthesis. Supporting these results, interaction proteomics by immunoprecipitation coupled to nano LC-MS/MS mass spectrometry revealed ERβ association with several potential nuclear protein partners, including key components of regulatory complexes known to control chromatin remodeling, transcriptional and post-transcriptional gene regulation and RNA splicing. Among these, ERβ association with the Polycomb Repressor Complexes 1 and 2 (PRC1/2), known for their central role in gene regulation in cancer cells, was confirmed in all three TNBC subtypes investigated, suggesting its occurrence independently from the cellular context. These results demonstrate a significant impact of ERβ in TNBC genome activity mediated by its cooperation with regulatory multiprotein chromatin remodeling complexes, providing novel ground to devise new strategies for the treatment of these diseases based on ligands affecting the activity of this nuclear receptor or some of its protein partners.

Repression of sphingosine kinase (SK)-interacting protein (SKIP) in acute myeloid leukemia diminishes SK activity and its re-expression restores SK function [Molecular Bases of Disease]

Previous studies have shown that sphingosine kinase interacting protein (SKIP) inhibits sphingosine kinase (SK) function in fibroblasts. SK phosphorylates sphingosine producing the potent signaling molecule sphingosine-1-phosphate (S1P). SKIP gene (SPHKAP) expression is silenced by hypermethylation of its promoter in acute myeloid leukemia (AML). However, why SKIP activity is silenced in primary AML cells is unclear. Here, we investigated the consequences of SKIP down-regulation in AML primary cells and the effects of SKIP re-expression in leukemic cell lines. Using targeted ultra-HPLC-tandem MS (UPLC-MS/MS), we measured sphingolipids (including S1P and ceramides) in AML and control cells. Primary AML cells had significantly lower SK activity and intracellular S1P concentrations than control cells, and SKIP-transfected leukemia cell lines exhibited increased SK activity. These findings show that SKIP re-expression enhances SK activity in leukemia cells. Furthermore, other bioactive sphingolipids such as ceramide were also down-regulated in primary AML cells. Of note, SKIP re-expression in leukemia cells increased ceramide levels 2-fold, inactivated the key signaling protein extracellular signal-regulated kinase, and increased apoptosis following serum deprivation or chemotherapy. These results indicate that SKIP down-regulation in AML reduces SK activity and ceramide levels, an effect that ultimately inhibits apoptosis in leukemia cells. The findings of our study contrast with previous results indicating that SKIP inhibits SK function in fibroblasts and therefore challenge the notion that SKIP always inhibits SK activity.

AIG1 and ADTRP are endogenous hydrolases of fatty acid esters of hydroxy fatty acids (FAHFAs) in mice [Metabolism]

Fatty acid esters of hydroxy fatty acids (FAHFAs) are a newly discovered class of signaling lipids with anti-inflammatory and anti-diabetic properties. However, the endogenous regulation of FAHFAs remains a pressing but unanswered question. Here, using MS-based FAHFA hydrolysis assays, LC-MS–based lipidomics analyses, and activity-based protein profiling, we found that androgen-induced gene 1 (AIG1) and androgen-dependent TFPI-regulating protein (ADTRP), two threonine hydrolases, control FAHFA levels in vivo in both genetic and pharmacologic mouse models. Tissues from mice lacking ADTRP (Adtrp-KO), or both AIG1 and ADTRP (DKO) had higher concentrations of FAHFAs particularly isomers with the ester bond at the 9th carbon due to decreased FAHFA hydrolysis activity. The levels of other lipid classes were unaltered indicating that AIG1 and ADTRP specifically hydrolyze FAHFAs. Complementing these genetic studies, we also identified a dual AIG1/ADTRP inhibitor, ABD-110207, which is active in vivo. Acute treatment of WT mice with ABD-110207 resulted in elevated FAHFA levels, further supporting the notion that AIG1 and ADTRP activity control endogenous FAHFA levels. However, loss of AIG1/ADTRP did not mimic the changes associated with pharmacologically administered FAHFAs on extent of upregulation of FAHFA levels, glucose tolerance, or insulin sensitivity in mice, indicating that therapeutic strategies should weigh more on FAHFA administration. Together, these findings identify AIG1 and ADTRP as the first endogenous FAHFA hydrolases identified and provide critical genetic and chemical tools for further characterization of these enzymes and endogenous FAHFAs to unravel their physiological functions and roles in health and disease.

Chinese Overseas Direct Investment and the Economic Crisis: Reaching Out

1 January 2009 , Number 5

Decisions taken today will determine the course of events for a generation. Nowhere is this truer than over the question of China’s investment abroad. This issue lies at the heart of what part the country will play in the global finance and trade system, and how it will work with the rest of the world in laying the foundations for longer term growth and stability after the current crisis is over.
