nat Webinar: Reimagining the Role of State and Non-State Actors in (Re)building National Health Systems in the Arab World By feedproxy.google.com Published On :: Wed, 15 Apr 2020 14:15:01 +0000 Research Event 22 April 2020 - 1:00pm to 2:00pm Event participants Fadi El-Jardali, Professor of Health Policy and Systems, American University of BeirutModerator: Nadim Houry, Executive Director, Arab Reform Initiative As new cases of COVID-19 continue to surge, countries around the world struggle to mitigate the public health and economic effects of the virus. It is becoming increasingly clear that an effective pandemic response requires a whole-of-government, whole-of-society approach. In the Arab world, where health systems are already strained by armed conflicts and displaced populations, a whole-of-society response to the pandemic is particularly critical as countries have become increasingly dependent on non-state actors, notably the private sector, for healthcare provision and any response that includes the state alone may not be sufficient to address the pandemic.In a recent article, Fadi El-Jardali, argued that while the pandemic will have grave health and economic consequences for years to come, it brings with it a valuable opportunity to re-envision the role of state and non-state actors in strengthening health systems. The article addressed the need for increased collaboration between state and non-state actors, and the rethinking of existing cooperation models to provide quality healthcare services for all. In this webinar, part of the Chatham House project on the future of the state in the Middle East and North Africa, Dr El-Jardali will discuss how state and non-state actors can collaborate more effectively to address the shortcomings of national health care systems amidst the pandemic and beyond. The article’s author will share insights on the different capacities available in Arab societies that governments can draw upon to ensure that Universal Health Coverage, equity considerations and social justice are at the core of health systems.You can express your interest in attending by following this link.

nat The hibernating 100S complex is a target of ribosome-recycling factor and elongation factor G in Staphylococcus aureus [Protein Synthesis and Degradation] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 The formation of translationally inactive 70S dimers (called 100S ribosomes) by hibernation-promoting factor is a widespread survival strategy among bacteria. Ribosome dimerization is thought to be reversible, with the dissociation of the 100S complexes enabling ribosome recycling for participation in new rounds of translation. The precise pathway of 100S ribosome recycling has been unclear. We previously found that the heat-shock GTPase HflX in the human pathogen Staphylococcus aureus is a minor disassembly factor. Cells lacking hflX do not accumulate 100S ribosomes unless they are subjected to heat exposure, suggesting the existence of an alternative pathway during nonstressed conditions. Here, we provide biochemical and genetic evidence that two essential translation factors, ribosome-recycling factor (RRF) and GTPase elongation factor G (EF-G), synergistically split 100S ribosomes in a GTP-dependent but tRNA translocation-independent manner. We found that although HflX and the RRF/EF-G pair are functionally interchangeable, HflX is expressed at low levels and is dispensable under normal growth conditions. The bacterial RRF/EF-G pair was previously known to target only the post-termination 70S complexes; our results reveal a new role in the reversal of ribosome hibernation that is intimately linked to bacterial pathogenesis, persister formation, stress responses, and ribosome integrity.

nat Britain should treat Europe as its ‘inner circle’ or risk losing international influence By feedproxy.google.com Published On :: Mon, 19 Oct 2015 09:05:23 +0000 13 October 2015 20151019BritanEuropeWorld.jpg British Prime Minister David Cameron sits with other world leaders at the G20 summit in Brisbane, Australia on 15 November 2014. Photo by Getty Images. Given the international context, it is in Britain’s best interests to treat Europe as the ‘inner circle’ of its foreign, security and international economic policy, argues Dr Robin Niblett, director of Chatham House, in a new paper.The British government’s approach since 2010 of seeking to enhance the UK's relations with the world’s emerging powers while balancing these with relationships with the United States and Europe has had only limited success. With constrained resources, and in the face of intense global economic competition, mounting security challenges and decaying international institutions, trying to commit the UK equally on all three fronts will not succeed in the future.Britain, Europe and the World: Rethinking the UK’s Circles of Influence calls for a different mindset and strategy towards the UK’s place in the world – one in which Britain is surrounded by three concentric circles of influence:The first or ‘inner circle’ is the EU, the region with which the UK’s relationships need to be strongest and most active.The ‘second circle’ consists of the protective and enabling set of economic and security relationships with the US.Finally, an ‘outer circle’ comprises the UK’s other key bilateral and institutional relationships.Should the UK vote to remain in the EU, policy-makers should commit to placing the EU at the centre of Britain's foreign policy, using the country’s economic weight, diplomatic skills and networks to play a leading role in leveraging more effective EU-wide policies. Should the country vote to leave, the UK and the EU would enter an extended period of dislocation before arriving at a new, mutually diminished settlement. British policy-makers would be forced to deal and negotiate with the EU on critical policy issues from the outside. It is hard to see, argues Dr Niblett, how that could lead to EU policies or an international context more in line with British interests. Despite its structural flaws and competing national interests, the EU offers the best prospects for managing the rapidly changing global context, for three main reasons:First, it allows the UK to leverage the EU’s global economic weight to enhance the UK’s economic interests internationally, including securing beneficial trade agreements and contributing to EU and global standard-setting and rule-writing. Conversely, leaving would require the UK to renegotiate over 100 trade agreements, and would disadvantage UK interests in EU markets, including making EU governments less likely to liberalize services. Second, it gives the UK a say in designing new EU initiatives to strengthen both British and European security in the face of diverse threats, whether managing the flow of refugees and other emigrants; combatting terrorism; or managing a more assertive Russia and the fallout from a disintegrating Middle East. Third, cooperating with other EU members offers a way of maximizing opportunities to find joint solutions to shared problems, whether in terms of responding to climate change; managing growing cyber insecurity; reversing the decay of governance in failing states; or combating the rise of dangerous non-state actors.Dr Robin Niblett said:‘Britain is likely to be richer, safer and more influential in the coming decades if it treats Europe as the ‘inner circle’ of its foreign policy. For a mid-sized country like the UK, being a major player in a strong regional institution can offer a critical lever for international influence. In the UK’s case, this means choosing to be a leading player in the world’s principal civilian power, the European Union.’ Editor's notes Read Britain, Europe and the World: Rethinking the UK's Circles of InfluenceChatham House will host a press briefing with Dr Robin Niblett on Monday 19 October at 11:00-11:45 BST.

However, given the current climate of austerity, the imminent end of the Afghanistan operation and recent events in Ukraine, crucial questions are being raised regarding the Alliance’s future priorities.

Over the course of this year, Chatham House convened a series of expert roundtables to answer some of these questions. This report draws on the findings of those meetings and makes recommendations for NATO’s next steps in the lead-up to its 2014 Summit in Wales.The paper suggests six principal actions for NATO:Find ways to caucus smaller groups within NATO rather than requiring all 28 members to make all decisions. NATO’s 28 member states all have their own interests and appetites for risk and bring diverse capabilities to the table. Yet rather than being a source of weakness, these differences of opinion can become a strength if properly managed. Enhance interoperability. With operations in Afghanistan winding down, and in light of declining defence spending, NATO militaries must find new ways to improve their ability to work with one another on the ground, at sea and in the air. Improve planning and positioning of forces together. For meaningful joint defence planning, and to share the burden of resources and responsibilities, NATO needs to facilitate collaborative discussions on challenges and capabilities. Develop better acquisition systems. In the context of declining defence spending, bridging the gap between strategy and resources will require NATO members to streamline acquisition systems, make tough choices about national defence industries, and become more collaborative on procurement. Rebuild public understanding and support for NATO. Public support is vital if member-state politicians are to make hard internal decisions on resources and to demonstrate the will and resilience required for effective deterrence and reassurance. Build on NATO’s partnerships and differentiate them better. With defence budgets tightening, NATO needs to recognize and take advantage of the fact that many non-NATO states and other institutions have similar interests to those of members.

nat NATO Could Play a De-escalating Role in the Russia-Turkey Confrontation By feedproxy.google.com Published On :: Fri, 27 Nov 2015 11:20:45 +0000 27 November 2015 Dr Beyza Unal Senior Research Fellow, International Security Programme @beyzaunal Google Scholar The Alliance must explore its options for negotiating small-scale incidents between member states and partner nations, if it ever hopes to build a coherent coalition to fight ISIS. 20151127RussiaTurkey.jpg Paper planes are seen among debris outside the Turkish embassy in Moscow on 25 November 2015 after an anti-Turkey picket. Photo by Getty Images. In the wake of the Paris attacks and the destruction of a Russian plane by a bomb in Sinai, Russia had been once more calling for a new level of engagement with Western partners over operations in Syria. Even an ‘anti-terrorism coalition’ appeared to gain traction after the terrorist attacks in Paris. But Russian attacks on Western-backed opposition groups in Syria and continuing violation of Turkish airspace narrowed the window of opportunity for engagement between NATO member states and Russia in Syria, and Tuesday’s incident – where Turkey shot down a Russian bomber − fundamentally challenged this option. NATO allies and Secretary General Jens Stoltenberg were quick to call for ‘calm and de-escalation’ of the situation. But they face a problem: in the absence of a strategy, NATO lacks a mechanism—a form of transparent process for crisis resolution—between member states and partner nations when and if a dispute or disagreement arises.NATO has three essential core tasks—collective defence (Article 5), crisis management and cooperative security; it does not prioritize one task over the other. Whereas collective defence applies to member states like Turkey, cooperative security involves engagement with partner nations, such as Russia, to assure Euro-Atlantic security. NATO’s role, in this sense, goes beyond protecting a member’s state’s sovereignty. This aspiration to provide enduring cooperation and cooperative security beyond members lies behind the now-obsolete NATO-Russia Founding Act on Mutual Relations, Cooperation and Security, signed in 1997.NATO’s balance between these tasks and its role vis-à-vis partner states is ill-defined, and among the core issues the Alliance must consider at or before its next summit in Warsaw in July 2016. These discussions must include prioritizing and grouping partner nations—Russia and Sweden, for instance, are clearly not partners in equal terms – and clarifying the role of the NATO-Russia Council (NRC). The NRC is a venue for political dialogue that includes consultation, cooperation and joint action, but does not have a crisis resolution mechanism. From 2014 onwards, the NRC has not functioned, yet it is the only venue where NATO and Russia could have discussions regarding the future of Syria, focusing on ISIS as a major threat both to the Alliance and to the partner nations. Neither Russia nor the Alliance will benefit from escalation; thus, both sides should bear in mind that a troubling partnership is better than an adversarial relationship.This is even more important because NATO member states do not have a cohesive strategy regarding Syria’s future. For some countries, like Germany, the efforts lie on refugee relief policies, while for others, such as France, the focus is the military fight against ISIS. Russia is clearly testing NATO’s response mechanisms through hybrid warfare techniques. Yet, NATO also does not have a coherent policy regarding Russia’s assertiveness in Ukraine, involvement in Syria and its annexation of Crimea. NATO officials are in general agreement that there can be ‘no grand bargain with Russia’ as long as it continues to violate international treaties and norms. Russian aggression and assertiveness is a long-term problem for the Alliance to tackle. So far, though, NATO benefits from ‘avoid[ing] that situations, incidents and accidents spiral out of control’, as the NATO secretary general noted in his speech after the extraordinary North Atlantic Council meeting. Solidarity among allies and protecting Turkish territorial integrity is a clear role for NATO, but the Alliance’s response mechanism in crisis situations should not be exhausted and undermined with small-scale, bilateral disagreements and disputes.NATO could move to incorporate a crisis resolution mechanism, in specified non-escalatory terms and processes, between member states and partner states, where NATO member states and Russia meet together as equals in case of a crisis. This could re-establish a communication channel between NATO and Russia in particular, especially when the NRC is not functioning. If such a mechanism were in existence today, Turkey could have taken the issue to NATO’s crisis management system and pointed out its concerns over airspace violations, rather than shooting down the Russian bomber. This could have enabled the Alliance and Russia to participate in a dialogue that has been silent for more than a year. Instead, this incident demonstrates the delicate strategy of balancing deterrence policies with engagement between a member state and a rather troubling partner nation.When Syria’s future is discussed, as it will be, at the Warsaw summit, Russia will be an unavoidable part of the discussion. But until there is a way to de-escalate these small-scale incidents, it will be increasingly difficult for Russia and NATO to determine whether they do in fact have any scope for cooperation, or at the least collaboration, on shared challenges and threats.To comment on this article, please contact Chatham House Feedback Full Article
nat NATO Hopes to Assure Allies While Saving Refugees By feedproxy.google.com Published On :: Fri, 11 Mar 2016 10:05:37 +0000 11 March 2016 Dr Beyza Unal Senior Research Fellow, International Security Programme @beyzaunal Google Scholar NATO’s mission in the Aegean Sea seems aimed as much at deterring Russia as saving lives. It could lead to confrontation. 2016-03-11-BundesmarineB.jpg Early last month NATO launched a new maritime security mission, ostensibly to prevent people smuggling across the Aegean Sea. This mission, however, was not originally a reaction to the humanitarian catastrophe at sea. Instead, it was a response to growing Russian assertiveness.A maritime patrol unit was first discussed in the North Atlantic Council in December 2015, when the Alliance agreed to provide a ‘tailored package of assurances’ to Ankara in a period of heightened tensions after Turkey shot down a Russian jet. The package included measures such as early reconnaissance planes (AWACS), air policing, naval presence in the Eastern Mediterranean, provisions for Maritime Patrol Aircrafts (MPA) and Intelligence, Surveillance & Reconnaissance (ISR), and port visits. None of the discussion at the time linked it with protecting refugees. Now framing this decision in that light creates a new mission for NATO’s Maritime Command (MARCOM), a mission that it has never conducted before.Neither NATO’s founding documents or the most recent 2010 Strategic Concept provide for this type of mission, and NATO units are not trained to carry out an actual rescue mission. Protecting strategic assets and goods, such as oil tankers, escorting naval vessels providing food into conflict zones, deterring piracy and monitoring the Mediterranean for terrorist activity have been the main priorities for MARCOM in the post-Cold War period. These activities and maritime exercises were aimed at defence against non-state actors.The positioning of NATO’s maritime fleet in the Aegean Sea to save refugees, however, has the potential to be used as a deterrent against Russia’s Anti Access/Anti-Denial capacity in the eastern Mediterranean. Russia, meanwhile, has increased its naval presence at the Tartus naval base in Syria, which it has used to support its air campaigns in Syria. This level of reciprocated military build-up is hard to sustain in the long-run. NATO−Russia tensionsOver the past few years, Russia’s assertive policies – its multiple military operations, the continuing modernization of its army and ‘simulated attacks’ such as the one in 2013 that tested Sweden’s air defence response mechanisms − have increasingly worried the Alliance and its partners. Clashing interests over Syria’s future and Russia’s attacks against the Western-supported rebel groups have also served to increase tensions between NATO member states and Russia. Recent analysis logged 60 dangerous incidents in the Euro-Atlantic area between Russia and NATO counties in the period between March 2014 and March 2015. NATO’s preparedness has been severely tested by these incidents, and has led the alliance to strengthen its presence on Europe’s southern flank.Such increased tensions could create a situation whereby accidents and miscalculations lead to escalation. NATO forces and Russia are already engaged in further force posturing − the decision to accelerate Montenegro’s accession to NATO and the increased conduct of wartime exercises, such as NATO’s search for submarines in open waters (Dynamic Manta 2016), reconnaissance operations (Cold Operation 16) or Russia’s simulated exercises, for instance – which could undermine global stability. Three weeks after the Russian jet was shot down, a Russian patrol ship fired warning shots at a Turkish vessel to attract attention and avoid a collision. This event did not escalate but given the heightened tensions, similar events may spiral out of control. The tentative cease-fire in Syria is a confidence building measure that could normalize and rebuild relations. But further steps should be taken to establish political dialogue, open up the channels for potential meetings at the NATO−Russia Council, and increase transparency and risk mitigation in exercises and activities.

Photo: Getty Images. At the United Nations general assembly in September, all countries, including South Africa, reaffirmed their commitment to achieving universal health coverage by 2030. This is achieved when everybody accesses the health services they need without suffering financial hardship.As governments outlined their universal health coverage plans, it was noticeable that some had made much faster progress than others, with some middle-income countries outperforming wealthier nations. For example, whereas Thailand, Ecuador and Georgia (with national incomes similar to South Africa) are covering their entire populations, in the United States, 30 million people still lack health insurance and expensive health bills are the biggest cause of personal bankruptcy.The key factor in financing universal health coverage is, therefore, not so much the level of financing but rather how the health sector is financed. You cannot cover everyone through private financing (including insurance) because the poor will be left behind. Instead, the state must step in to force wealthy and healthy members of society to subsidise services for the sick and the poor.Switching to a predominantly publicly financed health system is, therefore, a prerequisite for achieving universal health coverage.The National Health Insurance (NHI) Bill, recently presented to parliament, is President Cyril Ramaphosa’s strategy to make this essential transition. In essence, it proposes creating a health-financing system in which people pay contributions (mostly through taxes) according to their ability to pay and then receive health services according to their health needs.Surprisingly, these reforms have been dubbed 'controversial' by some commentators in the South African media, even though this is the standard route to universal health coverage as exhibited by countries across Europe, Asia, Australasia, Canada and much of Latin America.In criticising the NHI other stakeholders (often with a vested interest in preserving the status quo) have said that the government’s universal health coverage strategy is unaffordable because it will require higher levels of public financing for health.Evidence from across the world shows that this is patently false. South Africa already spends more than 8% of its national income on its health sector, which is very high for its income level. Turkey, for example (a good health performer and slightly richer than South Africa), spends 4.3% of its GDP and Thailand (a global universal health coverage leader) spends only 3.7%. Thailand shows what can be accomplished, because it launched its celebrated universal health coverage reforms in 2002 when its GDP per capita was only $1 900 — less than a third of South Africa’s today.In fact, Thailand’s prime minister famously ignored advice from the World Bank that it could not afford publicly financed, universal health coverage in the aftermath of the Asian financial crisis when it extended universal, tax-financed healthcare to the entire population. When these reforms proved a great success, a subsequent president of the World Bank, Dr Jim Kim, congratulated the Thai government for ignoring its previous advice.Similarly the United Kingdom, Japan and Norway all launched successful universal health coverage reforms at times of great economic difficulty at the end of World War II. These should be salutary lessons for those saying that South Africa can’t afford the NHI. If anything, because universal health reforms generate economic growth (with returns 10 times the public investment), now is exactly the time to launch the NHI.So there is enough overall funding in the South African health sector to take a giant step towards universal health coverage. The problem is that the current system is grossly inefficient and inequitable because more than half of these funds are spent through private insurance schemes that cover only 16% of the population — and often don’t cover even this population effectively.Were the bulk of these resources to be channelled through an efficient public financing system, evidence from around the world shows that the health sector would achieve better health outcomes, at lower cost. Health and income inequalities would fall, too.It’s true that in the long term, the government will have to increase public financing through reducing unfair subsidies to private health insurance and increasing taxes. But what the defenders of the current system don’t acknowledge is that, at the same time, private voluntary financing will fall, rapidly. Most families will no longer feel the need to purchase expensive private insurance when they benefit from the public system. It’s this fact that is generating so much opposition to the NHI from the private insurance lobby.This is the situation with the National Health Service in the UK and health systems across Europe, where only a small minority choose to purchase additional private insurance. Among major economies, only the United States continues to exhibit high levels of private, voluntary financing.As a consequence, it now spends an eye-watering 18% of its GDP on health and has some of the worst health indicators in the Organisation for Economic Co-operation and Development, including rising levels of maternal mortality. If South Africa doesn’t socialise health financing this is where its health system will end up — a long way from universal health coverage.What countries celebrating their universal health coverage successes at the UN have shown is that it is cheaper to publicly finance health than leave it to the free market. This is because governments are more efficient and fairer purchasers of health services than individuals and employers. As Dr Gro Harlem Brundtland, the former director general of the World Health Organization, said in New York: 'If there is one lesson the world has learnt, it is that you can only reach UHC [universal health coverage] through public financing.'This is a step South Africa must take — it can’t afford not to.This article was originally published by the Mail & Guardian.

nat The Hurdles to Developing a COVID-19 Vaccine: Why International Cooperation is Needed By feedproxy.google.com Published On :: Thu, 23 Apr 2020 09:26:36 +0000 23 April 2020 Professor David Salisbury CB Associate Fellow, Global Health Programme LinkedIn Dr Champa Patel Director, Asia-Pacific Programme @patel_champa 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 A biologist works on the virus inactivation process in Belo Horizonte, Brazil on 24 March 2020. The Brazilian Ministry of Health convened The Technological Vaccine Center to conduct research on COVID-19 in order to diagnose, test and develop a vaccine. Photo: Getty Images. 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 developmentFirstly, 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 manufacturingDevelopers, 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 distributionGlobal 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.

At the same time, the organization is reliant on an international order that the current coronavirus crisis is, arguably, disrupting: as containment measures become more important in stemming the spread of the virus, the temptation to implement protectionist policies is increasing among nations. For example, the UK did not participate in an EU scheme to buy PPE and Germany has accused the US of ‘piracy’ after it reportedly diverted a shipment of masks intended for Berlin. Elsewhere, despite rhetorical commitments from the G7 and G20, a detailed plan for a comprehensive international response has not been forthcoming. The panel will discuss issues of coordination and cooperation in the international response to COVID-19. Have global trends prior to the outbreak contributed to the slow and disjointed international response? How has the pandemic exposed fissures in the extent to which nations are willing to cooperate? And what is the capacity of international organizations such as the WHO to coordinate a concerted transnational response and what could the implications be for the future of globalization and the international liberal order?This event is open to Chatham House Members.

nat The histone H4 basic patch regulates SAGA-mediated H2B deubiquitination and histone acetylation [DNA and Chromosomes] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Histone H2B monoubiquitylation (H2Bub1) has central functions in multiple DNA-templated processes, including gene transcription, DNA repair, and replication. H2Bub1 also is required for the trans-histone regulation of H3K4 and H3K79 methylation. Although previous studies have elucidated the basic mechanisms that establish and remove H2Bub1, we have only an incomplete understanding of how H2Bub1 is regulated. We report here that the histone H4 basic patch regulates H2Bub1. Yeast cells with arginine-to-alanine mutations in the H4 basic patch (H42RA) exhibited a significant loss of global H2Bub1. H42RA mutant yeast strains also displayed chemotoxin sensitivities similar to, but less severe than, strains containing a complete loss of H2Bub1. We found that the H4 basic patch regulates H2Bub1 levels independently of interactions with chromatin remodelers and separately from its regulation of H3K79 methylation. To measure H2B ubiquitylation and deubiquitination kinetics in vivo, we used a rapid and reversible optogenetic tool, the light-inducible nuclear exporter, to control the subcellular location of the H2Bub1 E3 ligase, Bre1. The ability of Bre1 to ubiquitylate H2B was unaffected in the H42RA mutant. In contrast, H2Bub1 deubiquitination by SAGA-associated Ubp8, but not by Ubp10, increased in the H42RA mutant. Consistent with a function for the H4 basic patch in regulating SAGA deubiquitinase activity, we also detected increased SAGA-mediated histone acetylation in H4 basic patch mutants. Our findings uncover that the H4 basic patch has a regulatory function in SAGA-mediated histone modifications. Full Article

nat The hibernating 100S complex is a target of ribosome-recycling factor and elongation factor G in Staphylococcus aureus [Protein Synthesis and Degradation] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 The formation of translationally inactive 70S dimers (called 100S ribosomes) by hibernation-promoting factor is a widespread survival strategy among bacteria. Ribosome dimerization is thought to be reversible, with the dissociation of the 100S complexes enabling ribosome recycling for participation in new rounds of translation. The precise pathway of 100S ribosome recycling has been unclear. We previously found that the heat-shock GTPase HflX in the human pathogen Staphylococcus aureus is a minor disassembly factor. Cells lacking hflX do not accumulate 100S ribosomes unless they are subjected to heat exposure, suggesting the existence of an alternative pathway during nonstressed conditions. Here, we provide biochemical and genetic evidence that two essential translation factors, ribosome-recycling factor (RRF) and GTPase elongation factor G (EF-G), synergistically split 100S ribosomes in a GTP-dependent but tRNA translocation-independent manner. We found that although HflX and the RRF/EF-G pair are functionally interchangeable, HflX is expressed at low levels and is dispensable under normal growth conditions. The bacterial RRF/EF-G pair was previously known to target only the post-termination 70S complexes; our results reveal a new role in the reversal of ribosome hibernation that is intimately linked to bacterial pathogenesis, persister formation, stress responses, and ribosome integrity.

nat NF-{kappa}B mediates lipopolysaccharide-induced alternative pre-mRNA splicing of MyD88 in mouse macrophages [Signal Transduction] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 Although a robust inflammatory response is needed to combat infection, this response must ultimately be terminated to prevent chronic inflammation. One mechanism that terminates inflammatory signaling is the production of alternative mRNA splice forms in the Toll-like receptor (TLR) signaling pathway. Whereas most genes in the TLR pathway encode positive mediators of inflammatory signaling, several, including that encoding the MyD88 signaling adaptor, also produce alternative spliced mRNA isoforms that encode dominant-negative inhibitors of the response. Production of these negatively acting alternatively spliced isoforms is induced by stimulation with the TLR4 agonist lipopolysaccharide (LPS); thus, this alternative pre-mRNA splicing represents a negative feedback loop that terminates TLR signaling and prevents chronic inflammation. In the current study, we investigated the mechanisms regulating the LPS-induced alternative pre-mRNA splicing of the MyD88 transcript in murine macrophages. We found that 1) the induction of the alternatively spliced MyD88 form is due to alternative pre-mRNA splicing and not caused by another RNA regulatory mechanism, 2) MyD88 splicing is regulated by both the MyD88- and TRIF-dependent arms of the TLR signaling pathway, 3) MyD88 splicing is regulated by the NF-κB transcription factor, and 4) NF-κB likely regulates MyD88 alternative pre-mRNA splicing per se rather than regulating splicing indirectly by altering MyD88 transcription. We conclude that alternative splicing of MyD88 may provide a sensitive mechanism that ensures robust termination of inflammation for tissue repair and restoration of normal tissue homeostasis once an infection is controlled.

nat An enzyme-based protocol for cell-free synthesis of nature-identical capsular oligosaccharides from Actinobacillus pleuropneumoniae serotype 1 [Enzymology] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 Actinobacillus pleuropneumoniae (App) is the etiological agent of acute porcine pneumonia and responsible for severe economic losses worldwide. The capsule polymer of App serotype 1 (App1) consists of [4)-GlcNAc-β(1,6)-Gal-α-1-(PO4-] repeating units that are O-acetylated at O-6 of the GlcNAc. It is a major virulence factor and was used in previous studies in the successful generation of an experimental glycoconjugate vaccine. However, the application of glycoconjugate vaccines in the animal health sector is limited, presumably because of the high costs associated with harvesting the polymer from pathogen culture. Consequently, here we exploited the capsule polymerase Cps1B of App1 as an in vitro synthesis tool and an alternative for capsule polymer provision. Cps1B consists of two catalytic domains, as well as a domain rich in tetratricopeptide repeats (TPRs). We compared the elongation mechanism of Cps1B with that of a ΔTPR truncation (Cps1B-ΔTPR). Interestingly, the product profiles displayed by Cps1B suggested processive elongation of the nascent polymer, whereas Cps1B-ΔTPR appeared to work in a more distributive manner. The dispersity of the synthesized products could be reduced by generating single-action transferases and immobilizing them on individual columns, separating the two catalytic activities. Furthermore, we identified the O-acetyltransferase Cps1D of App1 and used it to modify the polymers produced by Cps1B. Two-dimensional NMR analyses of the products revealed O-acetylation levels identical to those of polymer harvested from App1 culture supernatants. In conclusion, we have established a protocol for the pathogen-free in vitro synthesis of tailored, nature-identical App1 capsule polymers. Full Article
nat Quantification of the affinities of CRISPR-Cas9 nucleases for cognate protospacer adȷacent motif (PAM) sequences [Molecular Biophysics] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The CRISPR/Cas9 nucleases have been widely applied for genome editing in various organisms. Cas9 nucleases complexed with a guide RNA (Cas9–gRNA) find their targets by scanning and interrogating the genomic DNA for sequences complementary to the gRNA. Recognition of the DNA target sequence requires a short protospacer adjacent motif (PAM) located outside this sequence. Given that the efficiency of target location may depend on the strength of interactions that promote target recognition, here we sought to compare affinities of different Cas9 nucleases for their cognate PAM sequences. To this end, we measured affinities of Cas9 nucleases from Streptococcus pyogenes, Staphylococcus aureus, and Francisella novicida complexed with guide RNAs (gRNAs) (SpCas9–gRNA, SaCas9–gRNA, and FnCas9–gRNA, respectively) and of three engineered SpCas9–gRNA variants with altered PAM specificities for short, PAM-containing DNA probes. We used a “beacon” assay that measures the relative affinities of DNA probes by determining their ability to competitively affect the rate of Cas9–gRNA binding to fluorescently labeled target DNA derivatives called “Cas9 beacons.” We observed significant differences in the affinities for cognate PAM sequences among the studied Cas9 enzymes. The relative affinities of SpCas9–gRNA and its engineered variants for canonical and suboptimal PAMs correlated with previous findings on the efficiency of these PAM sequences in genome editing. These findings suggest that high affinity of a Cas9 nuclease for its cognate PAM promotes higher genome-editing efficiency. Full Article
nat Unpacking the role of religion in political transnationalism: the case of the Shi'a Iraqi diaspora since 2003 By feedproxy.google.com Published On :: Wed, 04 Mar 2020 12:58:04 +0000 4 March 2020 , Volume 96, Number 2 Oula Kadhum Read Online This article explores the role of religion in political transnationalism using the case of the Shi'a Iraqi diaspora since 2003. The article focuses on three areas that capture important trends in Shi'a transnationalism and their implications for transnational Shi'a identity politics. These include Shi'a diasporic politics, transnational Shi'a civic activism, and the cultural production of Iraqi Shi'a identity through pilgrimages, rituals and new practices. It is argued that understanding Shi'a Islam and identity formation requires adopting a transnational lens. The evolution of Shi'a Islam is not only a result of the dictates of the Shi'a clerical centres, and how they influence Shi'a populations abroad, but also the transnational interrelationships and links to holy shrine cities, Shi'i national and international politics, humanitarianism and commemorations and rituals. The article demonstrates that Shi'a political transnationalism is unexceptional in that it echoes much of the literature on diasporic politics and development where diaspora involve themselves from afar in the politics and societies of their countries of origin. At the same time, it shows the exceptionalism of Shi'a diasporic movements, in that their motivations and mobilizations are contributing to the reification of sectarian geographical and social borders, creating a transnationalism that is defined by largely Shi'a networks, spaces, actors and causes. The case of Shi'a political transnationalism towards Iraq shows that this is increasing the distance between Shi'is and Iraq's other communities, simultaneously fragmenting Iraq's national unity while deepening Shi'a identity and politics both nationally and supra-nationally.

nat Webinar: Reimagining the Role of State and Non-State Actors in (Re)building National Health Systems in the Arab World By feedproxy.google.com Published On :: Wed, 15 Apr 2020 14:15:01 +0000 Research Event 22 April 2020 - 1:00pm to 2:00pm Event participants Fadi El-Jardali, Professor of Health Policy and Systems, American University of BeirutModerator: Nadim Houry, Executive Director, Arab Reform Initiative As new cases of COVID-19 continue to surge, countries around the world struggle to mitigate the public health and economic effects of the virus. It is becoming increasingly clear that an effective pandemic response requires a whole-of-government, whole-of-society approach. In the Arab world, where health systems are already strained by armed conflicts and displaced populations, a whole-of-society response to the pandemic is particularly critical as countries have become increasingly dependent on non-state actors, notably the private sector, for healthcare provision and any response that includes the state alone may not be sufficient to address the pandemic.In a recent article, Fadi El-Jardali, argued that while the pandemic will have grave health and economic consequences for years to come, it brings with it a valuable opportunity to re-envision the role of state and non-state actors in strengthening health systems. The article addressed the need for increased collaboration between state and non-state actors, and the rethinking of existing cooperation models to provide quality healthcare services for all. In this webinar, part of the Chatham House project on the future of the state in the Middle East and North Africa, Dr El-Jardali will discuss how state and non-state actors can collaborate more effectively to address the shortcomings of national health care systems amidst the pandemic and beyond. The article’s author will share insights on the different capacities available in Arab societies that governments can draw upon to ensure that Universal Health Coverage, equity considerations and social justice are at the core of health systems.You can express your interest in attending by following this link.

Frequently, actors capitalize on loopholes and inefficiencies resulting from the lack of a coordinated response to financial crime and an underpowered global system for tracking illicit financial flows. Enhanced public-private partnerships, in addition to investment in tackling financial crime from governments, international bodies and private industries, are necessary to develop regulatory frameworks, effective responses and valuable coordination between law enforcement, policymakers, regulators and financial institutions. But how should businesses structure their efforts so that their business interests are protected and the work they do is of use to others fighting financial crime?This webinar will explore solutions to enable public-private partnerships to work together to combat financial crime. What do successful partnerships need from each side to ensure that the work being done is efficient and effective? How can the industry’s internal effectiveness impact the ‘real-world’ victims? And what barriers impede public-private partnerships operating as a force for good?

In April 2020, UN Secretary General Antonio Guterres called for a global ceasefire in order for communities and states to focus efforts on responding to the coronavirus outbreak. The consequences of armed conflict – including displacement, detention, lack of access to health services and disrupted social infrastructures – mean that those in conflict-ridden areas are amongst the most vulnerable to the virus. Observing international humanitarian law (IHL) could be one way of safeguarding against, at least, the provision of vital medical supplies and personnel for vulnerable groups. Against the backdrop of a growing health and economic emergency that is otherwise dominating government agendas, how do we emphasise the importance of humanitarian action and guarantee - or improve - compliance?The panellists will discuss the remit and limitations of international humanitarian law and how the pandemic might complicate compliance.

But the coronavirus pandemic is just one of several existential crises the world is currently facing. Climate change, political instability and growing tensions with China and Russia, along with a lack of strong global leadership, has made it more difficult for individual nations to respond and coalesce in times of crisis.This discussion will explore how leaders at all levels can best negotiate both the practical issues and the larger questions associated with these ‘grand challenges’. How is current US foreign policy affecting our collective ability to respond to issues such as pandemics or climate change? Has the COVID-19 crisis cemented the US retreat from global leadership and if so, who might step into the breach? How do we maintain momentum on other issues in the midst of a public health disaster of this magnitude? And what is the role of the business community, higher education institutions and other sectors in responding to these crises and shaping future public policy?This event is only open to Major Corporate Member and Partner organizations and selected giving circles of Chatham House.

Though the 'new Iraq' attempts to project an independent foreign policy, renewed instability and violence inside the country has challenged the state's ability to develop a coherent and unified foreign policy stance.Jane Kinninmont and Gareth Stansfield will present the findings of their new report which explores how foreign policy in Iraq today is developed and implemented, and analyses the extent to which Iraq's foreign policy aims are identifiable, independent and national in nature. They will also engage in a wider discussion with an expert panel on Iraqi foreign policy, particularly towards the conflict in Syria and how issues in neighbouring states are intertwined with domestic Iraqi politics.

Syria has become the most divisive foreign policy issue facing Iraq, with little consensus on how to respond to the conflict. To protect against the risk of spillover from Syria, Iraq's political groupings must develop at least a basic agreement on their strategic response to the conflict. Western governments should caution their allies in the Gulf that the exploitation of sectarian discourses will have toxic effects that could last for at least a generation.More on Iraq Related documents Programme Report: Iraq on the International Stage: Foreign Policy and National Identity in Transition pdf | 532.64 KB Department/project Middle East and North Africa Programme, Future Dynamics in the Gulf Full Article

Estimates from June 2019 have placed the number of migrants at nearly double of what they were in 2018 with the increase in numbers stemming from a lack of economic opportunity combined with a rise in crime and insecurity in the region. The impacts of migration can already be felt within the affected states as the exodus has played a significant role in weakening labour markets and contributing to a ‘brain drain’ in the region. It has also played an increasingly active role in the upcoming US presidential election with some calling for more security on the border to curb immigration while others argue that a more effective strategy is needed to address the sources of migration. What are the core causes of Central American migration and how have the US, Central American and now also Mexican governments facilitated and deterred migration from the region? Can institutions be strengthened to alleviate the causes of migration? And what possible policy alternatives and solutions are there that could alleviate the pressures individuals and communities feel to migrate? Anita Isaacs, professor of Political Science at Haverford College and co-director of the Migration Encounters Project, and Juan Ricard Ortega, principal advisor for Central America at the Inter-American Development Bank, will join us for a discussion on the core drivers of migration within and across Central America.Attendance at this event is by invitation only.

Since assuming office, President Trump has withdrawn the US from the Joint Comprehensive Plan of Action, withdrawn troops from Syria, relocated the US embassy in Israel to Jerusalem and orchestrated the strike against ISIS leader Abu Bakr al-Baghdadi.Against a backdrop of Trump's inclination towards withdrawing from the region, countries across the Middle East are being rocked by protests, Turkey’s purchase of Russia’s S-400 missile has threatened to undermine cohesion within NATO and the much hoped for ceasefire in Libya between UN-backed government leader, Fayez al-Sarraj, and opposition leader, Khalifa Haftar, failed to materialize.In light of the upcoming US elections in November 2020, the future of US national security policy promises to be a prominent issue for the next administration. In this vein, the US and Americas Programme at Chatham House plans a yearlong focus on the pivotal US 2020 elections.At this event, Dr Kori Schake, director of foreign and defense policy studies at the American Enterprise Institute will discuss the future of US foreign policy towards the Middle East. How have domestic and party politics in the US – and the unfolding presidential campaign – shaped recent policy decisions by the Trump administration? Should we expect policy objectives in the Middle East to remain consistent or shift under a second Trump term? And what direction could US foreign policy towards the region take under a Democratic administration?Attendance at this event is by invitation only.

nat Trade, Technology and National Security: Will Europe Be Trapped Between the US and China? By feedproxy.google.com Published On :: Fri, 07 Feb 2020 15:25:01 +0000 Invitation Only Research Event 2 March 2020 - 8:00am to 9:15am Chatham House | 10 St James's Square | London | SW1Y 4LE Event participants Sir Simon Fraser, Managing Partner of Flint Global; Deputy Chairman, Chatham HouseChair: Marianne Schneider-Petsinger, Senior Research Fellow, US and the Americas Programme, Chatham House The US and China have entered into an increasingly confrontational relationship over trade and technology. This may force Europe to make difficult choices between the two economic superpowers – or perform a balancing act. Although the recent US-China phase-1 trade deal has eased the relationship for now, the trade and technology tensions are a structural issue and are likely to persist.The debate over Huawei’s participation in 5G networks is an example of how the UK and other countries may face competing priorities in economic, security and foreign policy. Can Europe avoid a binary choice between the US and China? Is it possible for the EU to position itself as a third global power in trade, technology and standard-setting? What strategies should Europeans adopt to keep the US and China engaged in the rules-based international order and what does the future hold for trade multilateralism?Sir Simon Fraser will join us for a discussion on Europe’s future role between the US and China. Sir Simon is Managing Partner of Flint Global and Deputy Chairman of Chatham House. He previously served as Permanent Secretary at the Foreign and Commonwealth Office (FCO) and Head of the UK Diplomatic Service from 2010 to 2015. Prior to that he was Permanent Secretary at the UK Department for Business, Innovation and Skills.

nat A kainate receptor-selective RNA aptamer [Neurobiology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Kainate and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are two major, closely related receptor subtypes in the glutamate ion channel family. Excessive activities of these receptors have been implicated in a number of central nervous system diseases. Designing potent and selective antagonists of these receptors, especially of kainate receptors, is useful for developing potential treatment strategies for these neurological diseases. Here, we report on two RNA aptamers designed to individually inhibit kainate and AMPA receptors. To improve the biostability of these aptamers, we also chemically modified these aptamers by substituting their 2'-OH group with 2'-fluorine. These 2'-fluoro aptamers, FB9s-b and FB9s-r, were markedly resistant to RNase-catalyzed degradation, with a half-life of ∼5 days in rat cerebrospinal fluid or serum-containing medium. Furthermore, FB9s-r blocked AMPA receptor activity. Aptamer FB9s-b selectively inhibited GluK1 and GluK2 kainate receptor subunits, and also GluK1/GluK5 and GluK2/GluK5 heteromeric kainate receptors with equal potency. This inhibitory profile makes FB9s-b a powerful template for developing tool molecules and drug candidates for treatment of neurological diseases involving excessive activities of the GluK1 and GluK2 subunits.
