State Cyber Interventions Below the Threshold of the Use of Force: Challenges in the Application of International Law

Chair: Elizabeth Wilmshurst, Distinguished Fellow, International Law Programme, Chatham House
Under what circumstances will a state-sponsored cyberattack on another state that falls below the threshold of the use of force be a breach of international law – for example, hacking into another state’s electoral databases, usurping inherently governmental functions such as parliamentary processes or an attack on another state’s financial system? In the dynamic field of state cyber operations, persistent, low-level cyberattacks are increasing, as are multilateral attempts to attribute the attacks to the states responsible. There is general agreement that international law applies to cyberspace but the question is how it applies and with what consequences.
This meeting will bring together a small group of academics and practitioners to explore the application of international law to states’ cyber operations that interfere in the internal affairs of another state and which fall below the threshold of the use of force. What is the law on non-intervention in international law and how does it apply to states’ cyber activities? Does the Nicaragua case represent the best expression of the law in this area including the requirement of coercion? And are there any other principles of international law that are relevant? The meeting will also consider processes and procedures for agreeing on the law and best practices.
The purpose of the meeting will be to inform a research paper by Chatham House.

Certain ortho-hydroxylated brominated ethers are promiscuous kinase inhibitors that impair neuronal signaling and neurodevelopmental processes [Cell Biology]
The developing nervous system is remarkably sensitive to environmental signals, including disruptive toxins, such as polybrominated diphenyl ethers (PBDEs). PBDEs are an environmentally pervasive class of brominated flame retardants whose neurodevelopmental toxicity mechanisms remain largely unclear. Using dissociated cortical neurons from embryonic Rattus norvegicus, we found here that chronic exposure to 6-OH–BDE-47, one of the most prevalent hydroxylated PBDE metabolites, suppresses both spontaneous and evoked neuronal electrical activity. On the basis of our previous work on mitogen-activated protein kinase (MAPK)/extracellular signal-related kinase (ERK) (MEK) biology and our observation that 6-OH–BDE-47 is structurally similar to kinase inhibitors, we hypothesized that certain hydroxylated PBDEs mediate neurotoxicity, at least in part, by impairing the MEK–ERK axis of MAPK signal transduction. We tested this hypothesis on three experimental platforms: 1) in silico, where modeling ligand–protein docking suggested that 6-OH–BDE-47 is a promiscuous ATP-competitive kinase inhibitor; 2) in vitro in dissociated neurons, where 6-OH–BDE-47 and another specific hydroxylated BDE metabolite similarly impaired phosphorylation of MEK/ERK1/2 and activity-induced transcription of a neuronal immediate early gene; and 3) in vivo in Drosophila melanogaster, where developmental exposures to 6-OH–BDE-47 and a MAPK inhibitor resulted in offspring displaying similarly increased frequency of mushroom-body β–lobe midline crossing, a metric of axonal guidance. Taken together, our results support that certain ortho-hydroxylated PBDE metabolites are promiscuous kinase inhibitors and can cause disruptions of critical neurodevelopmental processes, including neuronal electrical activity, pre-synaptic functions, MEK–ERK signaling, and axonal guidance.

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.

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.

Webinar: Can the Justice and Development Party Still Absorb Popular Anger in Morocco?
Webinar Research Event
8 April 2020 - 1:00pm to 2:00pm
Event participants
Mohammed Masbah, Director, Moroccan Institute for Policy Analysis; Associate Fellow, MENA Programme, Chatham House
Moderator: Lina Khatib, Director, MENA Programme, Chatham House
Ever since independence, the Moroccan monarchy has used political parties to legitimize the country’s authoritarian political process and structure, and to absorb social and political anger. The palace puts successive governments and other elected institutions, such as local and regional councils, at the frontline of public blame, and replaces them once they fail this function.
In a recent article, MENA Programme Associate Fellow, Mohammed Masbah, examines how the Moroccan monarchy has used this strategy with the ruling Justice and Development Party (PJD) so that the palace remains the centre of political power, while the PJD – and other political parties before it– takes responsibility for coping with the mounting socio-economic crisis.
In this webinar, part of the Chatham House project on The Future of the State in the Middle East and North Africa, the article’s author will discuss the risks this approach presents for the long-term stability of Morocco and what reforms are needed to increase citizens’ dwindling confidence in the political process.

212Pb Alpha-Radioimmunotherapy targeting CD38 in Multiple Myeloma: a preclinical study.
Multiple myeloma (MM) is a plasma cell cancer and represents the second most frequent hematological malignancy. Despite new treatments and protocols including high doses chemotherapy associated with autologous stem cell transplantation, the prognosis of MM patients is still poor. Alpha-radioimmunotherapy (alpha-RIT) represents an attractive treatment strategy due to the high linear energy transfer and short path length of alpha-radiation in tissues, resulting in high tumor cell killing and low toxicity to surrounding tissues. In this study, we investigated the potential of alpha-RIT with 212Pb-Daratumumab (anti-CD38), in both in vitro and in vivo models, as well as an anti-mouse CD38 antibody using in vivo models. Methods: Inhibition of cell proliferation after incubation of RPMI8226 cell line with increasing activities (0.185-3.7 kBq/ml) of 212Pb-isotypic control or 212Pb-Daratumumab was evaluated. Biodistribution was performed in vivo by SPECT-CT imaging and post-mortem. Dose range finding (DRF) and acute toxicity studies were conducted. As Daratumumab does not bind the murine CD38, biodistribution and DRF were also determined using an anti-murine CD38 antibody. To evaluate in vivo efficacy of 212Pb-Daratumumab, mice were engrafted subcutaneously with 5.106 RPMI8226 cells. Mice were treated 13 days post-engraftment with an intravenous injection of 212Pb-Daratumumab or control solutions. Therapeutic efficacy was monitored by tumor volume measurements and overall survival. Results: Significant inhibition of proliferation of the human myeloma RPMI8226 cell line was observed after three days of incubation with 212Pb-Daratumumab compared to 212Pb-Isotypic Control or cold antibodies. Biodistribution studies showed a specific tumoral accumulation of Daratumumab. No toxicity was observed with 212Pb-Daratumumab up to 370 kBq due to the lack of cross-reactivity. Nevertheless, acute toxicity experiments with 212Pb-anti-mCD38 established a toxic activity of 277.5 kBq. To remain within realistically safe treatment activities for efficacy studies, mice were treated with 185 kBq or 277.5 kBq of 212Pb-Daratumumab. Marked tumor growth inhibition compared to controls was observed, with a median survival of 55 days for 277.5 kBq of 212Pb-Daratumumab instead of 11 for PBS control groups. Conclusion: These results showed 212Pb-Daratumumab efficacy on xenografted mice with significant tumor regression and increased survival. This study highlights alpha-RIT potency in MM treatment.

Development and evaluation of interleukin-2 derived radiotracers for PET imaging of T-cells in mice
Recently, N-(4-18F-fluorobenzoyl)-interleukin-2 (18F-FB-IL2) was introduced as PET tracer for T-cell imaging. However, production is complex and time-consuming. Therefore, we developed two radiolabeled interleukin-2 (IL-2) variants, namely aluminum 18F-fluoride-(restrained complexing agent)-IL-2 (18F-AlF-RESCA-IL2) and 68Ga-gallium-(1,4,7-triazacyclononane-4,7-diacetic acid-1-glutaric acid)-IL-2 (68Ga-Ga-NODAGA-IL2) and compared their in-vitro and in-vivo characteristics with 18F-FB-IL2. Methods: Radiolabeling of 18F-AlF-RESCA-IL2 and 68Ga-Ga-NODAGA-IL2 was optimized and stability was evaluated in human serum. Receptor binding was studied with activated human peripheral blood mononuclear cells (hPBMCs). Ex-vivo tracer biodistribution in immunocompetent BALB/cOlaHsd (BALB/c) mice was performed at 15, 60 and 90 min after tracer injection. In-vivo binding characteristics were studied in severe combined immune-deficient (SCID) mice inoculated with activated hPBMCs in Matrigel. Tracer was injected 15 min after hPBMCs inoculation and a 60-min dynamic PET scan was acquired, followed by ex-vivo biodistribution studies. Specific uptake was determined by co-injection of tracer with unlabeled IL2 and by evaluating uptake in a control group inoculated with Matrigel only. Results: 68Ga-Ga-NODAGA-IL2 and 18F-AlF-RESCA-IL2 were produced with radiochemical purity >95% and radiochemical yield of 13.1±4.7% and 2.4±1.6% within 60 and 90 min, respectively. Both tracers were stable in serum, with >90% being intact tracer after 1h. In-vitro, both tracers displayed preferential binding to activated hPBMCs. Ex-vivo biodistribution studies in BALB/c mice showed higher uptake of 18F-AlF-RESCA-IL2 than 18F-FB-IL2 in liver, kidney, spleen, bone and bone marrow. 68Ga-Ga-NODAGA-IL2 uptake in liver and kidney was higher than 18F-FB-IL2 uptake. In-vivo, all tracers revealed uptake in activated hPBMCs in SCID mice. Low uptake was seen after a blocking dose of IL2 or in the Matrigel control group. In addition, 18F-AlF-RESCA-IL2 yielded highest contrast PET images of target lymph nodes. Conclusion: Production of 18F-AlF-RESCA-IL2 and 68Ga-Ga-NODAGA-IL2 is simpler and faster than 18F-FB-IL2. Both tracers showed good in-vitro and in-vivo characteristics with high uptake in lymphoid tissue and hPBMC xenografts.

Design and development of 99mTc labeled FAPI-tracers for SPECT-imaging and 188Re therapy.
The majority of epithelial tumors recruits fibroblasts and other non-malignant cells and activates them into cancer-associated fibroblasts. This often leads to overexpression of the membrane serine protease fibroblast-activating protein (FAP). It has already been shown that DOTA-bearing FAP inhibitors (FAPIs) generate high contrast images with PET/CT scans. Since SPECT is a lower cost and more widely available alternative to PET, 99mTc-labeled FAPIs represent attractive tracers for imaging applicable in a larger number of patients. Furthermore, the chemically homologous nuclide 188Re is available from generators, which allows FAP-targeted endoradiotherapy. Methods: For the preparation of 99mTc tricarbonyl complexes, a chelator was selected whose carboxylic acids can easily be converted into various derivatives in the finished product. This enabled a platform strategy based on the original tracer. The obtained 99mTc complexes were investigated in vitro by binding and competition experiments on FAP-transfected HT-1080 (HT-1080-FAP) and/or on mouse FAP expressing (HEK-muFAP) and CD26-expressing (HEKCD26) HEK cells and characterized by planar scintigraphy and organ distribution studies in tumor-bearing mice. Furthermore, a first-in-man application was done in two patients with ovarian and pancreatic cancer, respectively. Results: 99mTc-FAPI-19 showed specific binding to recombinant FAP-expressing cells with high affinity. Unfortunately, liver accumulation, biliary excretion and no tumor uptake were observed in the planar scintigraphy of a HT-1080-FAP xenotranplanted mouse. To improve the pharmacokinetic properties hydrophilic amino acids were attached to the chelator moiety of the compound. The resulting 99mTc-labeled FAPI tracers revealed excellent binding properties (up to 45 % binding; above 95 % internalization), high affinity (IC50 = 6.4 nM to 12.7 nM), and significant tumor uptake (up to 5.4 %ID/g) in biodistribution studies. The lead candidate 99mTc-FAPI-34 was applied for diagnostic scintigraphy and SPECT of patients with metastasized ovarian and pancreatic cancer for follow-up to therapy with 90Y-FAPI-46. 99mTc-FAPI-34 accumulated in the tumor lesions also shown in PET/CT imaging using 68Ga-FAPI-46. Conclusion: 99mTc-FAPI-34 represents a powerful tracer for diagnostic scintigraphy, especially in cases where PET imaging is not available. Additionally, the chelator used in this compound allows labeling with the therapeutic nuclide 188Re which is planned for the near future.

Hon Bruno Nabagné Kone, Minister of Construction, Housing and Urban Planning, Republic of Côte d'Ivoire
Strong economic growth in Côte d'Ivoire – with annual GDP growth averaging eight per cent since 2012 – is interlinked with an increase in spending on national infrastructure. In 2018, the government announced a $7 billion injection for the sector over five years, for projects including a new 7.5km bridge spanning two districts of Abidjan and a highway extending to Burkina Faso. A public-private partnership to build a new $1.5 billion metropolitan railway system in the capital received formal approval in October 2019.
But the government of Côte d'Ivoire has struggled to make the country’s impressive growth inclusive: Côte d’Ivoire ranked 165th out of 189 on the 2019 United Nations Human Development Index, and the poverty rate is around 46%. Translating significant infrastructural investment into benefit for ordinary and vulnerable Ivorian citizens, including through how project development is managed with communities, will be a critical issue in the lead up to elections scheduled for October 2020 and beyond.

Dr Hafez Ghanem discusses the implications of the COVID-19 pandemic for African economies and their development and poverty reduction efforts, and assesses the priorities and obstacles for establishing a comprehensive response to the crisis.
While the acute strain placed on health systems by the COVID-19 pandemic is already in evidence, the long-term economic fallout from the crisis is yet to fully manifest.
For Africa it is the economic impact that may leave the most enduring legacy: from the direct expense of measures to treat, detect and reduce the spread of the virus; to the indirect costs of domestic lockdown measures, global supply chain disruptions and plummeting commodity prices.
As decision-makers globally start to plan for the scale of this economic shock, strategizing in and on Africa to meet the challenge will require unprecedented planning and commitment - and will need to be matched by support from international partners to enable long-term recovery.

How images frame China's role in African development
7 May 2020 , Volume 96, Number 3
Political leaders, policy-makers and academics routinely refer to development as an objective process of social change through the use of technical, value-free terms. Images of poverty and inequality are regularly presented as evidence of a world that exists ‘out there’ where development unfolds. This way of seeing reflects the value of scientific forms of knowledge but also sits in tension with the normative foundations of development that take European modernization and industrialization as the benchmark for comparison. The role images play in this process is often overlooked. This article argues that a dominant mode of visuality based on a Cartesian separation between subject and object, underpinning the ascendance of European hegemony and colonialism, aligns with the core premises of orthodox development discourse. An example of how visual representations of development matter is presented through images of Africa–China relations in western media sources. Using widely circulated images depicting China's impact on African development in western news media sources as an example of why visual politics matters for policy-making, the article examines how images play a role in legitimizing development planning by rendering associated forms of epistemological and structural violence ‘invisible to the viewer’.

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.

How images frame China's role in African development
7 May 2020 , Volume 96, Number 3
Political leaders, policy-makers and academics routinely refer to development as an objective process of social change through the use of technical, value-free terms. Images of poverty and inequality are regularly presented as evidence of a world that exists ‘out there’ where development unfolds. This way of seeing reflects the value of scientific forms of knowledge but also sits in tension with the normative foundations of development that take European modernization and industrialization as the benchmark for comparison. The role images play in this process is often overlooked. This article argues that a dominant mode of visuality based on a Cartesian separation between subject and object, underpinning the ascendance of European hegemony and colonialism, aligns with the core premises of orthodox development discourse. An example of how visual representations of development matter is presented through images of Africa–China relations in western media sources. Using widely circulated images depicting China's impact on African development in western news media sources as an example of why visual politics matters for policy-making, the article examines how images play a role in legitimizing development planning by rendering associated forms of epistemological and structural violence ‘invisible to the viewer’.

The Hurdles to Developing a COVID-19 Vaccine: Why International Cooperation is Needed
23 April 2020
While the world pins its hopes on vaccines to prevent COVID-19, there are scientific, regulatory and market hurdles to overcome. Furthermore, with geopolitical tensions and nationalistic approaches, there is a high risk that the most vulnerable will not get the life-saving interventions they need.2020-04-23-Covid-Vaccine.jpg

On 10 January 2020, Chinese scientists released the sequence of the COVID-19 genome on the internet. This provided the starting gun for scientists around the world to start developing vaccines or therapies. With at least 80 different vaccines in development, many governments are pinning their hopes on a quick solution. However, there are many hurdles to overcome.
Vaccine development
Firstly, vaccine development is normally a very long process to ensure vaccines are safe and effective before they are used.
Safety is not a given: a recent dengue vaccine caused heightened disease in vaccinated children when they later were exposed to dengue, while Respiratory Syncytial Virus vaccine caused the same problem. Nor is effectiveness a given. Candidate vaccines that use novel techniques where minute fragments of the viruses’ genetic code are either injected directly into humans or incorporated into a vaccine (as is being pursued, or could be pursued for COVID-19) have higher risks of failure simply because they haven’t worked before. For some vaccines, we know what levels of immunity post-vaccination are likely to be protective. This is not the case for coronavirus.
Clinical trials will have to be done for efficacy. This is not optional – regulators will need to know extensive testing has taken place before licencing any vaccine. Even if animal tests are done in parallel with early human tests, the remainder of the process is still lengthy.
There is also great interest in the use of passive immunization, whereby antibodies to SARS-CoV-2 (collected from people who have recovered from infection or laboratory-created) are given to people who are currently ill. Antivirals may prove to be a quicker route than vaccine development, as the testing requirements would be shorter, manufacturing may be easier and only ill people would need to be treated, as opposed to all at-risk individuals being vaccinated.
Vaccine manufacturing
Developers, especially small biotechs, will have to make partnerships with large vaccine manufacturers in order to bring products to market. One notorious bottleneck in vaccine development is getting from proof-of-principle to commercial development: about 95 per cent of vaccines fail at this step. Another bottleneck is at the end of production. The final stages of vaccine production involve detailed testing to ensure that the vaccine meets the necessary criteria and there are always constraints on access to the technologies necessary to finalize the product. Only large vaccine manufacturers have these capacities. There is a graveyard of failed vaccine candidates that have not managed to pass through this development and manufacturing process.
Another consideration is adverse or unintended consequences. Highly specialized scientists may have to defer their work on other new vaccines to work on COVID-19 products and production of existing products may have to be set aside, raising the possibility of shortages of other essential vaccines.
Cost is another challenge. Vaccines for industrialized markets can be very lucrative for pharmaceutical companies, but many countries have price caps on vaccines. Important lessons have been learned from the 2009 H1N1 flu pandemic when industrialized countries took all the vaccines first. Supplies were made available to lower-income countries at a lower price but this was much later in the evolution of the pandemic. For the recent Ebola outbreaks, vaccines were made available at low or no cost.
Geopolitics may also play a role. Should countries that manufacture a vaccine share it widely with other countries or prioritize their own populations first? It has been reported that President Trump attempted to purchase CureVac, a German company with a candidate vaccine. There are certainly precedents for countries prioritizing their own populations. With H1N1 flu in 2009, the Australian Government required a vaccine company to meet the needs of the Australian population first.
Vaccine distribution
Global leadership and a coordinated and coherent response will be needed to ensure that any vaccine is distributed equitably. There have been recent calls for a G20 on health, but existing global bodies such as the Coalition for Epidemic Preparedness Innovations (CEPI) and GAVI are working on vaccines and worldwide access to them. Any new bodies should seek to boost funding for these entities so they can ensure products reach the most disadvantaged.
While countries that cannot afford vaccines may be priced out of markets, access for poor, vulnerable or marginalized peoples, whether in developed or developing countries, is of concern. Developing countries are at particular risk from the impacts of COVID-19. People living in conflict-affected and fragile states – whether they are refugees or asylum seekers, internally displaced or stateless, or in detention facilities – are at especially high risk of devastating impacts.
Mature economies will also face challenges. Equitable access to COVID-19 vaccine will be challenging where inequalities and unequal access to essential services have been compromised within some political systems.
The need for global leadership
There is an urgent need for international coordination on COVID-19 vaccines. While the WHO provides technical support and UNICEF acts as a procurement agency, responding to coronavirus needs clarity of global leadership that arches over national interests and is capable of mobilizing resources at a time when economies are facing painful recessions. We see vaccines as a salvation but remain ill-equipped to accelerate their development.
While everyone hopes for rapid availability of safe, effective and affordable vaccines that will be produced in sufficient quantities to meet everyone’s needs, realistically, we face huge hurdles.

Developments and Applications of Functional Protein Microarrays [Review]
Protein microarrays are crucial tools in the study of proteins in an unbiased, high-throughput manner, as they allow for characterization of up to thousands of individually purified proteins in parallel. The adaptability of this technology has enabled its use in a wide variety of applications, including the study of proteome-wide molecular interactions, analysis of post-translational modifications, identification of novel drug targets, and examination of pathogen-host interactions. In addition, the technology has also been shown to be useful in profiling antibody specificity, as well as in the discovery of novel biomarkers, especially for autoimmune diseases and cancers. In this review, we will summarize the developments that have been made in protein microarray technology in both in basic and translational research over the past decade. We will also introduce a novel membrane protein array, the GPCR-VirD array, and discuss the future directions of functional protein microarrays.

Perlecan knockdown significantly alters extracellular matrix composition and organization during cartilage development [Research]
Perlecan is a critical proteoglycan found in the extracellular matrix (ECM) of cartilage. In healthy cartilage, perlecan regulates cartilage biomechanics and we previously demonstrated perlecan deficiency leads to reduced cellular and ECM stiffness in vivo. This change in mechanics may lead to the early onset osteoarthritis seen in disorders resulting from perlecan knockdown such as Schwartz-Jampel syndrome (SJS). To identify how perlecan knockdown affects the material properties of developing cartilage, we used imaging and liquid chromatography–tandem mass spectrometry (LC-MS/MS) to study the ECM in a murine model of SJS, Hspg2C1532Y-Neo. Perlecan knockdown led to defective pericellular matrix formation, whereas the abundance of bulk ECM proteins, including many collagens, increased. Post-translational modifications and ultrastructure of collagens were not significantly different; however, LC-MS/MS analysis showed more protein was secreted by Hspg2C1532Y-Neo cartilage in vitro, suggesting that the incorporation of newly synthesized ECM was impaired. In addition, glycosaminoglycan deposition was atypical, which may explain the previously observed decrease in mechanics. Overall, these findings provide insight into the influence of perlecan on functional cartilage assembly and the progression of osteoarthritis in SJS.

At face value, recent years have seen a deepening in Sino-Russian cooperation, from energy agreements, to the recent Huawei-MTS deal developing a 5G network in Russia. Ever larger-in-scale joint military exercises add to fears by some that the 'axis of convenience' is now a more genuine – and threatening – partnership.
This workshop will offer a sober assessment of the latest developments in Sino-Russian relations, shedding light on the underpinnings and practical realities of the relationship as well as on the long-term challenges of upholding cooperation.
The panel will discuss the different and potentially diverging interpretations of contemporary Sino-Russian relations as well as the implications for the rules-based international order.
This event is co-organized by the Chatham House Russia and Eurasia Programme and the University of Exeter and is supported by the British International Studies Association.

Development of a sensitive and quantitative method for the identification of two major furan fatty acids in human plasma [Methods]
This article focuses on the establishment of an accurate and sensitive quantitation method for the analysis of furan fatty acids. In particular, the sensitivity of GC/MS and UPLC/ESI/MS/MS was compared for the identification and quantification of furan fatty acids. Different methylation methods were tested with respect to GC/MS analysis. Special attention needs to be paid to the methylation of furan fatty acids, as acidic catalysts might lead to the degradation of the furan ring. GC/MS analysis in full-scan mode demonstrated that the limit of quantitation was 10 μM. UPLC/ESI/MS/MS in multiple reaction monitoring mode displayed a higher detection sensitivity than GC/MS. Moreover, the identification of furan fatty acids with charge-reversal derivatization was tested in the positive mode with two widely used pyridinium salts. Significant oxidation was unexpectedly observed using N-(4-aminomethylphenyl) pyridinium as a derivatization agent. The formed 3-acyl-oxymethyl-1-methylpyridinium iodide derivatized by 2-bromo-1-methylpyridinium iodide and 3-carbinol-1-methylpyridinium iodide improved the sensitivity more than 2,000-fold compared with nonderivatization in the negative mode by UPLC/ESI/MS/MS. This charge-reversal derivatization enabled the targeted quantitation of furan fatty acids in human plasma. Thus, it is anticipated that this protocol could greatly contribute to the clarification of pathological mechanisms related to furan fatty acids and their metabolites.

Myeloid-specific deficiency of pregnane X receptor decreases atherosclerosis in LDL receptor-deficient mice [Research Articles]
The pregnane X receptor (PXR) is a nuclear receptor that can be activated by numerous drugs and xenobiotic chemicals. PXR thereby functions as a xenobiotic sensor to coordinately regulate host responses to xenobiotics by transcriptionally regulating many genes involved in xenobiotic metabolism. We have previously reported that PXR has pro-atherogenic effects in animal models, but how PXR contributes to atherosclerosis development in different tissues or cell types remains elusive. In this study, we generated an LDL receptor-deficient mouse model with myeloid-specific PXR deficiency (PXRMyeLDLR–/–) to elucidate the role of macrophage PXR signaling in atherogenesis. The myeloid PXR deficiency did not affect metabolic phenotypes and plasma lipid profiles, but PXRMyeLDLR–/– mice had significantly decreased atherosclerosis at both aortic root and brachiocephalic arteries compared with control littermates. Interestingly, the PXR deletion did not affect macrophage adhesion and migration properties, but reduced lipid accumulation and foam cell formation in the macrophages. PXR deficiency also led to decreased expression of the scavenger receptor CD36 and impaired lipid uptake in macrophages of the PXRMyeLDLR–/– mice. Further, RNA-Seq analysis indicated that treatment with a prototypical PXR ligand affects the expression of many atherosclerosis-related genes in macrophages in vitro. These findings reveal a pivotal role of myeloid PXR signaling in atherosclerosis development and suggest that PXR may be a potential therapeutic target in atherosclerosis management.

Elevated First-Trimester Neutrophil Count Is Closely Associated with the Development of Maternal Gestational Diabetes Mellitus and Adverse Pregnancy Outcomes
Chronic low-grade inflammation plays a central role in the pathophysiology of gestational diabetes mellitus (GDM). In order to investigate the ability of different inflammatory blood cell parameters in predicting the development of GDM and pregnancy outcomes, 258 women with GDM and 1154 women without were included in this retrospective study. First-trimester neutrophil count outperformed white blood cell (WBC) count, and neutrophil-to-lymphocyte ratio (NLR) in the predictability for GDM. Subjects were grouped based on tertiles of neutrophil count during their first-trimester pregnancy. The results showed that as the neutrophil count increased, there was a step-wise increase in GDM incidence, as well as glucose and glycosylated hemoglobin (HbA1c) level, Homeostasis Model Assessment for Insulin Resistance (HOMA-IR), macrosomia incidence and newborn weight. Neutrophil count was positively associated with pre-pregnancy Body Mass Index (BMI), HOMA-IR and newborn weight. Additionally, neutrophil count was an independent risk factor for the development of GDM, regardless of the history of GDM. Spline regression showed that there was a significant linear association between GDM incidence and continuous neutrophil count when it exceeded 5.0 x 109/L. This work suggested that first-trimester neutrophil count is closely associated with the development of GDM and adverse pregnancy outcomes.
