ca Closing the Global Access Gap in Palliative Care and Pain Relief: A Top Priority in Achieving Universal Health Coverage By feedproxy.google.com Published On :: Wed, 26 Jun 2019 13:50:01 +0000 Invitation Only Research Event 17 July 2019 - 12:30pm to 5:00pm Chatham House | 10 St James's Square | London | SW1Y 4LE Event participants Dr Tedros Adhanom Ghebreyesus, Director-General, World Health Organization The Lancet Commission on Palliative Care and Pain Relief estimated that in 2015, 61 million people experienced serious health-related suffering (SHS) that could have been ameliorated by palliative care. A large proportion of this burden – more than 80 per cent – fell on low- and middle-income countries (LMICs) despite an essential package of palliative care and pain relief services being cost-effective and affordable. As the director general of the World Health Organization (WHO) argues, there cannot be UHC without palliative care and thus, closing this coverage gap should be a top priority for the global UHC movement.The Centre on Global Health Security at Chatham House, building on the momentum of the Lancet Commission, is hosting a roundtable focused on the global unmet need for palliative care and effective pain relief. The primary purpose of this roundtable is to convene leading experts, palliative care service users and advocates with key figures from the UHC movement and global health to highlight the importance of prioritizing this vital part of the continuum of care in UHC reform processes. The roundtable will serve as a scholarly discourse in translating the recommendations of the Lancet Commission into concrete actions, focusing on the political and economic dimensions.

ca South Africa Can Easily Afford National Health Insurance By feedproxy.google.com Published On :: Mon, 09 Dec 2019 06:07:40 +0000 9 December 2019 Robert Yates Director, Global Health Programme; Executive Director, Centre for Universal Health @yates_rob Countries with much lower per capita GDP have successfully implemented universal healthcare. 2019-12-06-NMCH.jpg Builders work on an outside yard at the Nelson Mandela Children's Hospital in Johannesburg in 2016. 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.

ca WHO Can Do Better - But Halting Funding is No Answer By feedproxy.google.com Published On :: Mon, 20 Apr 2020 09:11:18 +0000 20 April 2020 Dr Charles Clift Senior Consulting Fellow, Global Health Programme @CliftWorks Calling a halt to funding for an unspecified time is an unsatisfactory halfway house for the World Health Organization (WHO) to deal with. But with Congress and several US agencies heavily involved, whether a halt is even feasible is under question. 2020-04-20-PPE-Ethiopia-WHO Checking boxes of personal protective equipment (PPE) at the Bole International Airport in Addis Ababa, Ethiopia. Photo by SAMUEL HABTAB/AFP via Getty Images. Donald Trump is impulsive. His sudden decision to stop funding the World Health Organization (WHO) just days after calling it 'very China-centric” and 'wrong about a lot of things' is the latest example. And this in the midst of the worst pandemic since Spanish flu in 1918 and a looming economic crisis compared by some to the 1930s. But the decision is not really just about what WHO might or might not have done wrong. It is more about the ongoing geopolitical wrangle between the US and China, and about diverting attention from US failings in its own response to coronavirus in the run-up to the US presidential election.It clearly also derives from Trump’s deep antipathy to almost any multilateral organization. WHO has been chosen as the fall guy in this political maelstrom in a way that might please Trump’s supporters who will have read or heard little about WHO’s role in tackling this crisis. And the decision has been widely condemned in almost all other countries and by many in the US.What is it likely to mean in practice for WHO?Calling a halt to funding for an unspecified time is an unsatisfactory halfway house. A so-called factsheet put out by the White House talks about the reforms it thinks necessary 'before the organization can be trusted again'. This rather implies that the US wants to remain a member of WHO if it can achieve the changes it wants. Whether those changes are feasible is another question — they include holding member states accountable for accurate data-sharing and countering what is referred to as 'China’s outsize influence on the organization'. Trump said the funding halt would last while WHO’s mismanagement of the coronavirus pandemic was investigated, which would take 60-90 days. The US is the single largest funder of WHO, providing about 16% of its budget. It provides funds to WHO in two ways. The first is the assessed contribution — the subscription each country pays to be a member. In 2018/19 the US contribution should have been $237 million but, as of January this year it was in arrears by about $200 million.Much bigger are US voluntary contributions provided to WHO for specified activities amounting in the same period to another $650 million. These are for a wide variety of projects — more than one-quarter goes to polio eradication, but a significant portion also is for WHO’s emergency work. The US assessed contribution represents only 4% of WHO’s budget. Losing that would certainly be a blow to WHO but a manageable one. Given the arrears situation it is not certain that the US would have paid any of this in the next three months in any case. More serious would be losing the US voluntary contributions which account for about another 12% of WHO’s budget—but whether this could be halted all at once is very unclear. First Congress allocates funds in the US, not the president, raising questions about how a halt could be engineered domestically.Secondly, US contributions to WHO come from about ten different US government agencies, such as the National Institutes of Health or USAID, each of whom have separate agreements with WHO. Will they be prepared to cut funding for ongoing projects with WHO? And does the US want to disrupt ongoing programmes such as polio eradication and, indeed, emergency response which contribute to saving lives? Given the president’s ability to do 180 degree U-turns we shall have to wait and see what will actually happen in the medium term. If it presages the US leaving WHO, this would only facilitate growing Chinese influence in the WHO and other UN bodies. Perhaps in the end wiser advice will be heeded and a viable solution found.Most of President Trump’s criticisms of WHO do not bear close scrutiny. WHO may have made mistakes — it may have given too much credence to information coming from the Chinese. China has just announced that the death toll in Wuhan was 50% higher than previously revealed. It may have overpraised China’s performance and system, but this was part of a deliberate strategy to secure China’s active collaboration so that it could help other countries learn from China’s experience. The chief message from this sorry story is that two countries are using WHO as a pawn in pursuing their respective political agendas which encompass issues well beyond the pandemic. China has been very successful in gaining WHO’s seal of approval, in spite of concerns about events prior to it declaring the problem to the WHO and the world. This, in turn, has invited retaliation from the US. When this is over will be the time to learn lessons about what WHO should have done better. But China, the US, and the global community of nations also need to consider their own responsibility in contributing to this terrible unfolding tragedy.This article was originally published in the British Medical Journal Full Article
ca Beyond Lockdown: Africa’s Options for Responding to COVID-19 By feedproxy.google.com Published On :: Tue, 21 Apr 2020 15:42:52 +0000 21 April 2020 Ben Shepherd Consulting Fellow, Africa Programme Nina van der Mark Research Analyst, Global Health Programme @vdm_nina LinkedIn The continent’s enormous diversity means that there will be no one African experience of COVID-19, nor a uniform governmental response. But there are some common challenges across the continent, and a chance to get the response right. 2020-04-22-Africa-COVID-Dakar Dakar after the Interior Ministry announced compulsory wearing of masks in public and private services, shops and transport, under penalty of sanctions. Photo by SEYLLOU/AFP via Getty Images. African policymakers face a dilemma when it comes to COVID-19. The first hope is to prevent the virus from gaining a foothold at all, and many African states have significant experience of managing infectious disease outbreaks. The establishment of the Africa Centre for Disease Control highlights the hugely increased focus on public health in recent years.But capacities to track, test and isolate vary wildly, notably between neighbours with porous and poorly controlled borders and, in most cases, sustained national-level disease control is difficult. Initial clusters of COVID-19 cases are already established in many places, but a lack of testing capacity makes it hard to know the full extent of transmission.It is not obvious what African states should do as a response. Lack of information about COVID-19 means the proportion of asymptomatic or mild cases is not known, still less the ways in which this is influenced by human geography and demographics.Africa is an overwhelmingly young continent with a median age under 20. But it also faces chronic malnutrition, which may weaken immune responses, and infectious diseases such as malaria, TB and HIV are widespread which could worsen the impact of COVID-19, particularly if treatment for these diseases is interrupted.Complex and unknownUltimately, how all these factors interact with COVID-19 is complex and remains largely unknown. Africa may escape with a relatively light toll. Or it could be hit harder than anywhere else.What is clear, however, is that cost of simply following the rest of the world into lockdown could be high. Africa is relatively rural but has higher populations living in informal settlements than anywhere in the world. Many live in cramped and overcrowded accommodation without clean water or reliable electricity, making handwashing a challenge and working from home impossible.And the benefits appear limited. The goal of lockdowns in most places is not to eliminate the virus but to accept the economic and social costs as a price worth paying in order to ‘flatten the curve’ of infection and protect healthcare systems from being overwhelmed. But this logic does not hold when many of Africa’s healthcare systems are barely coping with pre-coronavirus levels of disease.Africa suffers in comparison to much of the rest of the world in terms of access to quality and affordable healthcare, critical care beds and specialist personnel. For example, in 2017, Nigeria had just 120 ICU beds for a country of 200 million, equating to 0.07 per 100,000 inhabitants compared to 12.5 per 100,000 in Italy and 3.6 per 100,000 in China.The pandemic’s ruinous economic impacts could also be more acute for Africa than anywhere else. The continent is highly vulnerable to potential drops in output and relies heavily on demand from China and Europe. Many states are already facing sharply falling natural resource revenues, and investment, tourism and remittances will suffer - all on top of a high existing debt burden.Analysis by the World Bank shows that Africa will likely face its first recession in 25 years, with the continental economy contracting by up to 5.1% in 2020. Africa will have scant financial ammunition to use in the fight against COVID-19 with currencies weakening, food prices rising, local agri-food supply chains disrupted and food imports likely to decrease as well. A food security emergency appears a strong possibility.So, although several states have imposed national lockdowns and others closed major urban centres, lockdowns are difficult to manage and sustain, especially in places where the daily hustle of the informal sector or subsistence agriculture are the only means of survival and where the state has neither the trust of the population nor the capacity to replace lost earnings or meet basic needs.Of course, this is not simply a binary choice between lockdown or no lockdown - a range of intermediate options exist, such as some restriction on movement, curfews, shutting places of worship, banning only large gatherings, or closing pubs, schools and borders.A significant number of African states have so far taken this middle path. This will not prevent the virus from spreading nor, in all probability, be enough to ensure adequate healthcare for all Africans infected with COVID-19. But it may help slow the spread and buy invaluable time for African states and partners to prepare.How this time is used is therefore of paramount importance. Popular trust in the state is low in many African countries so strategies must empower communities, not alienate them. Africa’s experience of previous epidemics and long traditions of collective resilience and community-based crisis response - which persist in many places – are significant strengths.The right messages must be carried by the right messengers, and policies - including cash transfers and food distribution - implemented sensitively. If not, or if responses become militarized, public consent is unlikely to be sustained for long. Full Article
ca SSO and other putative inhibitors of FA transport across membranes by CD36 disrupt intracellular metabolism, but do not affect FA translocation [Research Articles] By feedproxy.google.com Published On :: 2020-05-01T00:05:28-07:00 Membrane-bound proteins have been proposed to mediate the transport of long-chain FA (LCFA) transport through the plasma membrane (PM). These proposals are based largely on reports that PM transport of LCFAs can be blocked by a number of enzymes and purported inhibitors of LCFA transport. Here, using the ratiometric pH indicator (2',7'-bis-(2-carboxyethyl)-5-(and-6-)-carboxyfluorescein and acrylodated intestinal FA-binding protein-based dual fluorescence assays, we investigated the effects of nine inhibitors of the putative FA transporter protein CD36 on the binding and transmembrane movement of LCFAs. We particularly focused on sulfosuccinimidyl oleate (SSO), reported to be a competitive inhibitor of CD36-mediated LCFA transport. Using these assays in adipocytes and inhibitor-treated protein-free lipid vesicles, we demonstrate that rapid LCFA transport across model and biological membranes remains unchanged in the presence of these purported inhibitors. We have previously shown in live cells that CD36 does not accelerate the transport of unesterified LCFAs across the PM. Our present experiments indicated disruption of LCFA metabolism inside the cell within minutes upon treatment with many of the "inhibitors" previously assumed to inhibit LCFA transport across the PM. Furthermore, using confocal microscopy and a specific anti-SSO antibody, we found that numerous intracellular and PM-bound proteins are SSO-modified in addition to CD36. Our results support the hypothesis that LCFAs diffuse rapidly across biological membranes and do not require an active protein transporter for their transmembrane movement. Full Article
ca Nanodomains can persist at physiologic temperature in plasma membrane vesicles and be modulated by altering cell lipids [Research Articles] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 The formation and properties of liquid-ordered (Lo) lipid domains (rafts) in the plasma membrane are still poorly understood. This limits our ability to manipulate ordered lipid domain-dependent biological functions. Giant plasma membrane vesicles (GPMVs) undergo large-scale phase separations into coexisting Lo and liquid-disordered lipid domains. However, large-scale phase separation in GPMVs detected by light microscopy is observed only at low temperatures. Comparing Förster resonance energy transfer-detected versus light microscopy-detected domain formation, we found that nanodomains, domains of nanometer size, persist at temperatures up to 20°C higher than large-scale phases, up to physiologic temperature. The persistence of nanodomains at higher temperatures is consistent with previously reported theoretical calculations. To investigate the sensitivity of nanodomains to lipid composition, GPMVs were prepared from mammalian cells in which sterol, phospholipid, or sphingolipid composition in the plasma membrane outer leaflet had been altered by cyclodextrin-catalyzed lipid exchange. Lipid substitutions that stabilize or destabilize ordered domain formation in artificial lipid vesicles had a similar effect on the thermal stability of nanodomains and large-scale phase separation in GPMVs, with nanodomains persisting at higher temperatures than large-scale phases for a wide range of lipid compositions. This indicates that it is likely that plasma membrane nanodomains can form under physiologic conditions more readily than large-scale phase separation. We also conclude that membrane lipid substitutions carried out in intact cells are able to modulate the propensity of plasma membranes to form ordered domains. This implies lipid substitutions can be used to alter biological processes dependent upon ordered domains. Full Article
ca Hematopoiesis is regulated by cholesterol efflux pathways and lipid rafts: connections with cardiovascular diseases [Thematic Reviews] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 Lipid rafts are highly ordered regions of the plasma membrane that are enriched in cholesterol and sphingolipids and play important roles in many cells. In hematopoietic stem and progenitor cells (HSPCs), lipid rafts house receptors critical for normal hematopoiesis. Lipid rafts also can bind and sequester kinases that induce negative feedback pathways to limit proliferative cytokine receptor cycling back to the cell membrane. Modulation of lipid rafts occurs through an array of mechanisms, with optimal cholesterol efflux one of the major regulators. As such, cholesterol homeostasis also regulates hematopoiesis. Increased lipid raft content, which occurs in response to changes in cholesterol efflux in the membrane, can result in prolonged receptor occupancy in the cell membrane and enhanced signaling. In addition, certain diseases, like diabetes, may contribute to lipid raft formation and affect cholesterol retention in rafts. In this review, we explore the role of lipid raft-related mechanisms in hematopoiesis and CVD (specifically, atherosclerosis) and discuss how defective cholesterol efflux pathways in HSPCs contribute to expansion of lipid rafts, thereby promoting myelopoiesis and thrombopoiesis. We also discuss the utility of cholesterol acceptors in contributing to lipid raft regulation and disruption, and highlight the potential to manipulate these pathways for therapeutic gain in CVD as well as other disorders with aberrant hematopoiesis.

ca Lipid rafts as signaling hubs in cancer cell survival/death and invasion: implications in tumor progression and therapy [Thematic Reviews] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 Cholesterol/sphingolipid-rich membrane domains, known as lipid rafts or membrane rafts, play a critical role in the compartmentalization of signaling pathways. Physical segregation of proteins in lipid rafts may modulate the accessibility of proteins to regulatory or effector molecules. Thus, lipid rafts serve as sorting platforms and hubs for signal transduction proteins. Cancer cells contain higher levels of intracellular cholesterol and lipid rafts than their normal non-tumorigenic counterparts. Many signal transduction processes involved in cancer development (insulin-like growth factor system and phosphatidylinositol 3-kinase-AKT) and metastasis [cluster of differentiation (CD)44] are dependent on or modulated by lipid rafts. Additional proteins playing an important role in several malignant cancers (e.g., transmembrane glycoprotein mucin 1) are also being detected in association with lipid rafts, suggesting a major role of lipid rafts in tumor progression. Conversely, lipid rafts also serve as scaffolds for the recruitment and clustering of Fas/CD95 death receptors and downstream signaling molecules leading to cell death-promoting raft platforms. The partition of death receptors and downstream signaling molecules in aggregated lipid rafts has led to the formation of the so-called cluster of apoptotic signaling molecule-enriched rafts, or CASMER, which leads to apoptosis amplification and can be pharmacologically modulated. These death-promoting rafts can be viewed as a linchpin from which apoptotic signals are launched. In this review, we discuss the involvement of lipid rafts in major signaling processes in cancer cells, including cell survival, cell death, and metastasis, and we consider the potential of lipid raft modulation as a promising target in cancer therapy.

ca X-ray structures of catalytic intermediates of cytochrome c oxidase provide insights into its O2 activation and unidirectional proton-pump mechanisms [Molecular Biophysics] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 Cytochrome c oxidase (CcO) reduces O2 to water, coupled with a proton-pumping process. The structure of the O2-reduction site of CcO contains two reducing equivalents, Fea32+ and CuB1+, and suggests that a peroxide-bound state (Fea33+–O−–O−–CuB2+) rather than an O2-bound state (Fea32+–O2) is the initial catalytic intermediate. Unexpectedly, however, resonance Raman spectroscopy results have shown that the initial intermediate is Fea32+–O2, whereas Fea33+–O−–O−–CuB2+ is undetectable. Based on X-ray structures of static noncatalytic CcO forms and mutation analyses for bovine CcO, a proton-pumping mechanism has been proposed. It involves a proton-conducting pathway (the H-pathway) comprising a tandem hydrogen-bond network and a water channel located between the N- and P-side surfaces. However, a system for unidirectional proton-transport has not been experimentally identified. Here, an essentially identical X-ray structure for the two catalytic intermediates (P and F) of bovine CcO was determined at 1.8 Å resolution. A 1.70 Å Fe–O distance of the ferryl center could best be described as Fea34+ = O2−, not as Fea34+–OH−. The distance suggests an ∼800-cm−1 Raman stretching band. We found an interstitial water molecule that could trigger a rapid proton-coupled electron transfer from tyrosine-OH to the slowly forming Fea33+–O−–O−–CuB2+ state, preventing its detection, consistent with the unexpected Raman results. The H-pathway structures of both intermediates indicated that during proton-pumping from the hydrogen-bond network to the P-side, a transmembrane helix closes the water channel connecting the N-side with the hydrogen-bond network, facilitating unidirectional proton-pumping during the P-to-F transition.

ca Long noncoding RNA pncRNA-D reduces cyclin D1 gene expression and arrests cell cycle through RNA m6A modification [RNA] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 pncRNA-D is an irradiation-induced 602-nt long noncoding RNA transcribed from the promoter region of the cyclin D1 (CCND1) gene. CCND1 expression is predicted to be inhibited through an interplay between pncRNA-D and RNA-binding protein TLS/FUS. Because the pncRNA-D–TLS interaction is essential for pncRNA-D–stimulated CCND1 inhibition, here we studied the possible role of RNA modification in this interaction in HeLa cells. We found that osmotic stress induces pncRNA-D by recruiting RNA polymerase II to its promoter. pncRNA-D was highly m6A-methylated in control cells, but osmotic stress reduced the methylation and also arginine methylation of TLS in the nucleus. Knockdown of the m6A modification enzyme methyltransferase-like 3 (METTL3) prolonged the half-life of pncRNA-D, and among the known m6A recognition proteins, YTH domain-containing 1 (YTHDC1) was responsible for binding m6A of pncRNA-D. Knockdown of METTL3 or YTHDC1 also enhanced the interaction of pncRNA-D with TLS, and results from RNA pulldown assays implicated YTHDC1 in the inhibitory effect on the TLS–pncRNA-D interaction. CRISPR/Cas9-mediated deletion of candidate m6A site decreased the m6A level in pncRNA-D and altered its interaction with the RNA-binding proteins. Of note, a reduction in the m6A modification arrested the cell cycle at the G0/G1 phase, and pncRNA-D knockdown partially reversed this arrest. Moreover, pncRNA-D induction in HeLa cells significantly suppressed cell growth. Collectively, these findings suggest that m6A modification of the long noncoding RNA pncRNA-D plays a role in the regulation of CCND1 gene expression and cell cycle progression. Full Article
ca The single CCA-adding enzyme of T. brucei has distinct functions in the cytosol and in mitochondria [RNA] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 tRNAs universally carry a CCA nucleotide triplet at their 3'-ends. In eukaryotes, the CCA is added post-transcriptionally by the CCA-adding enzyme (CAE). The mitochondrion of the parasitic protozoan Trypanosoma brucei lacks tRNA genes and therefore imports all of its tRNAs from the cytosol. This has generated interest in the tRNA modifications and their distribution in this organism, including how CCA is added to tRNAs. Here, using a BLAST search for genes encoding putative CAE proteins in T. brucei, we identified a single ORF, Tb927.9.8780, as a potential candidate. Knockdown of this putative protein, termed TbCAE, resulted in the accumulation of truncated tRNAs, abolished translation, and inhibited both total and mitochondrial CCA-adding activities, indicating that TbCAE is located both in the cytosol and mitochondrion. However, mitochondrially localized tRNAs were much less affected by the TbCAE ablation than the other tRNAs. Complementation assays revealed that the N-terminal 10 amino acids of TbCAE are dispensable for its activity and mitochondrial localization and that deletion of 10 further amino acids abolishes both. A growth arrest caused by the TbCAE knockdown was rescued by the expression of the cytosolic isoform of yeast CAE, even though it was not imported into mitochondria. This finding indicated that the yeast enzyme complements the essential function of TbCAE by adding CCA to the primary tRNA transcripts. Of note, ablation of the mitochondrial TbCAE activity, which likely has a repair function, only marginally affected growth. Full Article
ca Chemical roadblocking of DNA transcription for nascent RNA display [RNA] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Site-specific arrest of RNA polymerases (RNAPs) is fundamental to several technologies that assess RNA structure and function. Current in vitro transcription “roadblocking” approaches inhibit transcription elongation by blocking RNAP with a protein bound to the DNA template. One limitation of protein-mediated transcription roadblocking is that it requires inclusion of a protein factor extrinsic to the minimal in vitro transcription reaction. In this work, we developed a chemical approach for halting transcription by Escherichia coli RNAP. We first established a sequence-independent method for site-specific incorporation of chemical lesions into dsDNA templates by sequential PCR and translesion synthesis. We then show that interrupting the transcribed DNA strand with an internal desthiobiotin-triethylene glycol modification or 1,N6-etheno-2'-deoxyadenosine base efficiently and stably halts Escherichia coli RNAP transcription. By encoding an intrinsic stall site within the template DNA, our chemical transcription roadblocking approach enables display of nascent RNA molecules from RNAP in a minimal in vitro transcription reaction.

ca RNA helicase-regulated processing of the Synechocystis rimO-crhR operon results in differential cistron expression and accumulation of two sRNAs [Gene Regulation] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The arrangement of functionally-related genes in operons is a fundamental element of how genetic information is organized in prokaryotes. This organization ensures coordinated gene expression by co-transcription. Often, however, alternative genetic responses to specific stress conditions demand the discoordination of operon expression. During cold temperature stress, accumulation of the gene encoding the sole Asp–Glu–Ala–Asp (DEAD)-box RNA helicase in Synechocystis sp. PCC 6803, crhR (slr0083), increases 15-fold. Here, we show that crhR is expressed from a dicistronic operon with the methylthiotransferase rimO/miaB (slr0082) gene, followed by rapid processing of the operon transcript into two monocistronic mRNAs. This cleavage event is required for and results in destabilization of the rimO transcript. Results from secondary structure modeling and analysis of RNase E cleavage of the rimO–crhR transcript in vitro suggested that CrhR plays a role in enhancing the rate of the processing in an auto-regulatory manner. Moreover, two putative small RNAs are generated from additional processing, degradation, or both of the rimO transcript. These results suggest a role for the bacterial RNA helicase CrhR in RNase E-dependent mRNA processing in Synechocystis and expand the known range of organisms possessing small RNAs derived from processing of mRNA transcripts.

President Trump has raised a number of issues regarding trade with China – including the US’s trade deficit with China and the naming of China as a currency manipulator. But at the heart of the ongoing tariff escalation are China’s policies and practices regarding forced technology transfer, intellectual property theft and non-market distortions.As China’s international influence has expanded it has always been unlikely that Beijing would continue to accept existing global standards and institutions established and widely practised by developed countries based on ‘the Washington Consensus’.China’s desire to be an alternative champion of technology standard-setting remains unfulfilled. Its ample innovation talent is a solid foundation in its quest for global technology supremacy but tightening controls over personal freedoms could undermine it and deter potential global partners.It is unclear if Chinese government interventions will achieve the technological self-sufficiency Beijing has long desired. China’s approach to macroeconomic management diverges significantly from that of the US and other real market economies, particularly in its policy towards nurturing innovation.Chinese actors are engaged in the globalization of technological innovation through exports and imports of high-tech goods and services; cross-border investments in technology companies and research and development (R&D) activities; cross-border R&D collaboration; and international techno-scientific research collaboration.While the Chinese state pushes domestic companies and research institutes to engage in the globalization of technological innovation, its interventions in the high-tech sector have caused uneasiness in the West.The current US response to its competition with China for technological supremacy, which leans towards decoupling, is unlikely to prove successful. The US has better chances of success if it focuses on America’s own competitiveness, works on common approaches to technology policy with like-minded partners around the globe and strengthens the international trading system.A technically sound screening mechanism of foreign investment can prevent normal cross-border collaboration in technological innovation from being misused by geopolitical rival superpowers.

ca The recalibration of Chinese assertiveness: China's responses to the Indo-Pacific challenge By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:14:26 +0000 8 January 2020 , Volume 96, Number 1 Read online Feng Liu In response to the changing geopolitical landscape in Asia, both China and the United States attempt to alter the regional order in their own favour, both in the economic and security realms. This article shows how diverging views on future arrangements are leading to strategic shifts and increasing tension between these two Great Powers. As part of its quest for Great-Power status, China has been actively pushing its regional initiatives such as the Belt and Road Initiative (BRI) and the Asian Infrastructure Investment Bank (AIIB), as well as adopting assertive security policies towards its neighbours. In contrast, in order to counter China's growing influence America's regional strategy is undergoing a subtle shift from ‘rebalancing to Asia’ to focusing on the ‘Indo-Pacific’ region. However, amid an intensifying trade war and other challenges facing the region, China has chosen to moderate its proactive foreign policy-orientation in the past few years. In particular, China has made attempts to downplay its domestic rhetoric, rebuild strategic relationship with India and Japan, and to reassure ASEAN states in the South China Sea. In response to the Indo-Pacific strategy, it would be more effective for China to articulate a more inclusive regional vision and promote an institutional framework that also accommodates a US presence in the region.

ca Non-traditional security cooperation between China and south-east Asia: implications for Indo-Pacific geopolitics By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:17:30 +0000 8 January 2020 , Volume 96, Number 1 Read online Xue Gong The ‘free and open Indo-Pacific’ (FOIP) strategy, actively promoted by the United States with support from its allies and partners, is a significant geopolitical response to China's growing power and expanding influence in Asia and beyond. Beijing has adopted various new strategies to cope with the challenges related to FOIP. One of these strategies is to secure a robust relationship with south-east Asia in order to make these regional states either neutral to or less supportive of the Indo-Pacific vision. In addition to economic statecraft and soft power, Beijing believes that it can also tap into the domain of non-traditional security (NTS) to strengthen relations with this region to position itself better in the intensifying regional geopolitical competition. The article addresses the following question: what is the impact of China's NTS cooperation with south-east Asia on Beijing's geopolitical rivalry with other major powers in the Indo-Pacific region? The article argues that China's NTS cooperation with south-east Asian countries may help China maintain its geopolitical standing in the region, but it is unlikely to lead to any dramatic increase of China's strategic influence in the region. This essentially means that Beijing may be able to prevent ASEAN or most ASEAN member states from lending substantive and strong support to the Indo-Pacific construct, but it will not be able to stop ASEAN states from supporting some elements of the FOIP.

ca Consigned to hedge: south-east Asia and America's ‘free and open Indo-Pacific’ strategy By feedproxy.google.com Published On :: Wed, 08 Jan 2020 11:47:11 +0000 8 January 2020 , Volume 96, Number 1 Read online See Seng Tan This article assesses how south-east Asian countries and the Association of Southeast Asian Nations (ASEAN) have responded to the ‘free and open Indo-Pacific’ (FOIP) strategies promoted by the United States and the other countries in the Quadrilateral Security Dialogue (the ‘Quad’: US, Japan, Australia and India). Their nuanced ripostes imply a persistent commitment to hedging and shifting limited alignments in the face of growing great rivalry and the lack of a clear FOIP vision among Quad members. In the face of external pressure to take sides, the ASEAN states are likely to keep hedging through working selectively with China and the United States. Given the United States' apparent preference to balance China and Trump's disregard for multilateralism, ASEAN's ability to maintain its centrality in the evolving regional architecture is in doubt—despite the Quad countries' (belated) accommodation of ASEAN in their FOIP strategies. However, the success of the US strategy depends on Washington's ability to build and sustain the requisite coalition to balance Beijing. ASEAN has undertaken efforts to enhance bilateral security collaboration with China and the United States respectively. In doing so, ASEAN is arguably seeking to informally redefine its centrality in an era of Great Power discord and its ramifications for multilateralism. Full Article
ca Developmental peace in east Asia and its implications for the Indo-Pacific By feedproxy.google.com Published On :: Wed, 08 Jan 2020 12:01:42 +0000 8 January 2020 , Volume 96, Number 1 Read online Ling Wei This article adopts a constructive approach to examining the problem of the Indo-Pacific construct. Through reflection on the east Asian experience, it proposes an analytical framework of developmental peace as a constellation of international practices, which means that the more economic development is prioritized by states in regional processes, the more likely it is that a sustainable peace will be achieved. States participating in regional integration comprise a community of practice. On the basis of a shared understanding that development is of overriding importance and underpins security and state legitimacy, the community takes economic development as the anchoring practice; this practice embodies and enacts constitutive rules and fundamental norms for a broader set of practices in regional processes, such as peaceful coexistence and non-interference. The more economic development is prioritized on domestic and regional agendas, the more likely it is that conflicts in the security realm will be relaxed or even resolved to protect security interests. The author draws some useful implications from the developmental peace in east Asia for the Indo-Pacific construct, among which the most important include building shared understandings on the prioritization of economic development, taking advantage of the Regional Comprehensive Economic Partnership (RCEP), Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the Asian Infrastructure Investment Bank, and using the code of conduct process as a vehicle and best practice to facilitate rule-making for the maritime order. Finally, the author briefly discusses the contributions of the study and limitations of the model. Full Article

While early estimates suggest that a recession is inevitable, differing countries in Asia are generally deploying modest fiscal and monetary measures. This is true even in China, compared with the ‘whatever it takes’ approach pursued by Europe and America. How effective will these measures be in reviving growth and in easing the pain, particularly on the poor in developing countries in Asia? Is Asia witnessing a sudden but temporary halt in economic activity rather than a prolonged slowdown? At this virtual roundtable, the speakers will consider the likelihood of a recovery for trade in the region and will explore what lessons can be learned from countries like Singapore, who seem to be successfully managing the health and economic aspects of COVID-19.

ca WHO Can Do Better - But Halting Funding is No Answer By feedproxy.google.com Published On :: Mon, 20 Apr 2020 09:11:18 +0000 20 April 2020 Dr Charles Clift Senior Consulting Fellow, Global Health Programme @CliftWorks Calling a halt to funding for an unspecified time is an unsatisfactory halfway house for the World Health Organization (WHO) to deal with. But with Congress and several US agencies heavily involved, whether a halt is even feasible is under question. 2020-04-20-PPE-Ethiopia-WHO Checking boxes of personal protective equipment (PPE) at the Bole International Airport in Addis Ababa, Ethiopia. Photo by SAMUEL HABTAB/AFP via Getty Images. Donald Trump is impulsive. His sudden decision to stop funding the World Health Organization (WHO) just days after calling it 'very China-centric” and 'wrong about a lot of things' is the latest example. And this in the midst of the worst pandemic since Spanish flu in 1918 and a looming economic crisis compared by some to the 1930s. But the decision is not really just about what WHO might or might not have done wrong. It is more about the ongoing geopolitical wrangle between the US and China, and about diverting attention from US failings in its own response to coronavirus in the run-up to the US presidential election.It clearly also derives from Trump’s deep antipathy to almost any multilateral organization. WHO has been chosen as the fall guy in this political maelstrom in a way that might please Trump’s supporters who will have read or heard little about WHO’s role in tackling this crisis. And the decision has been widely condemned in almost all other countries and by many in the US.What is it likely to mean in practice for WHO?Calling a halt to funding for an unspecified time is an unsatisfactory halfway house. A so-called factsheet put out by the White House talks about the reforms it thinks necessary 'before the organization can be trusted again'. This rather implies that the US wants to remain a member of WHO if it can achieve the changes it wants. Whether those changes are feasible is another question — they include holding member states accountable for accurate data-sharing and countering what is referred to as 'China’s outsize influence on the organization'. Trump said the funding halt would last while WHO’s mismanagement of the coronavirus pandemic was investigated, which would take 60-90 days. The US is the single largest funder of WHO, providing about 16% of its budget. It provides funds to WHO in two ways. The first is the assessed contribution — the subscription each country pays to be a member. In 2018/19 the US contribution should have been $237 million but, as of January this year it was in arrears by about $200 million.Much bigger are US voluntary contributions provided to WHO for specified activities amounting in the same period to another $650 million. These are for a wide variety of projects — more than one-quarter goes to polio eradication, but a significant portion also is for WHO’s emergency work. The US assessed contribution represents only 4% of WHO’s budget. Losing that would certainly be a blow to WHO but a manageable one. Given the arrears situation it is not certain that the US would have paid any of this in the next three months in any case. More serious would be losing the US voluntary contributions which account for about another 12% of WHO’s budget—but whether this could be halted all at once is very unclear. First Congress allocates funds in the US, not the president, raising questions about how a halt could be engineered domestically.Secondly, US contributions to WHO come from about ten different US government agencies, such as the National Institutes of Health or USAID, each of whom have separate agreements with WHO. Will they be prepared to cut funding for ongoing projects with WHO? And does the US want to disrupt ongoing programmes such as polio eradication and, indeed, emergency response which contribute to saving lives? Given the president’s ability to do 180 degree U-turns we shall have to wait and see what will actually happen in the medium term. If it presages the US leaving WHO, this would only facilitate growing Chinese influence in the WHO and other UN bodies. Perhaps in the end wiser advice will be heeded and a viable solution found.Most of President Trump’s criticisms of WHO do not bear close scrutiny. WHO may have made mistakes — it may have given too much credence to information coming from the Chinese. China has just announced that the death toll in Wuhan was 50% higher than previously revealed. It may have overpraised China’s performance and system, but this was part of a deliberate strategy to secure China’s active collaboration so that it could help other countries learn from China’s experience. The chief message from this sorry story is that two countries are using WHO as a pawn in pursuing their respective political agendas which encompass issues well beyond the pandemic. China has been very successful in gaining WHO’s seal of approval, in spite of concerns about events prior to it declaring the problem to the WHO and the world. This, in turn, has invited retaliation from the US. When this is over will be the time to learn lessons about what WHO should have done better. But China, the US, and the global community of nations also need to consider their own responsibility in contributing to this terrible unfolding tragedy.This article was originally published in the British Medical Journal Full Article

At a time when the world needs strong and collective leadership to fight the coronavirus, both countries have been locked in a battle of words characterized by escalating hostility, polarizing narratives, blame and misinformation. Caught in the crossfire, many people of Chinese descent across differing countries have reported an increase in xenophobic attacks.Middle powers such as the UK and Australia have swerved between recognition of the global collaboration needed to solve this pandemic and calls for China to be held ‘accountable’ for its initial response. Others such, as France and Japan, have been trying to foster international cooperation. Against this context, speakers will discuss China’s response to the crisis, including the initial delay and Beijing’s later containment strategies. How do we best assess the delay amidst all the heated rhetoric? What was the response of people within China to the measures? Does COVID-19 mark a point of no return for US-China relations? How might this impact on relations between US allies and China? And what kind of China will emerge from this current crisis?

ca Forecasting Crime Part 1 By www.ams.org Published On :: Tue, 21 Aug 2012 09:49:48 -0400 No one can predict who will commit a crime but in some cities math is helping detect areas where crimes have the greatest chance of occurring. Police then increase patrols in these "hot spots" in order to prevent crime. This innovative practice, called predictive policing, is based on large amounts of data collected from previous crimes, but it involves more than just maps and push pins. Predictive policing identifies hot spots by using algorithms similar to those used to predict aftershocks after major earthquakes. Just as aftershocks are more likely near a recent earthquake.s epicenter, so too are crimes, as criminals do indeed return to, or very close to, the scene of a crime. Cities employing this approach have seen crime rates drop and studies are underway to measure predictive policing.s part in that drop. One fact that has been determined concerns the nature of hot spots. Researchers using partial differential equations and bifurcation theory have discovered two types of hot spots, which respond quite differently to increased patrols. One type will shift to another area of the city while the other will disappear entirely. Unfortunately the two appear the same on the surface, so mathematicians and others are working to help police find ways to differentiate between the two so as to best allocate their resources.

ca Catching and Releasing: Part 2 By www.ams.org Published On :: Mon, 1 Oct 2012 09:46:50 -0400 There.s more mathematics involved in juggling than just trying to make sure that the number of balls (or chainsaws) that hits the ground stays at zero. Subjects such as combinatorics and abstract algebra help jugglers answer important questions, such as whether a particular juggling pattern can actually be juggled. For example, can balls be juggled so that the time period that each ball stays aloft alternates between five counts and one? The answer is Yes. Math also tells you that the number of balls needed for such a juggling pattern is the average of the counts, in this case three. Once a pattern is shown to be juggleable and the number of balls needed is known, equations of motion determine the speed with which each ball must be thrown and the maximum height it will attain. Obviously the harder a juggler throws, the faster and higher an object will go. Unfortunately hang time increases proportionally to the square root of the height, so the difficulty of keeping many objects in the air increases very quickly. Both math and juggling have been around for millennia yet questions still remain in both subjects.
