Photo: Getty Images. Epidemics, of the size of Covid-19, have huge economic impacts – not just from the costs of managing the health of people, but stopping them, and keeping the economy working. The 10% fall in global stock markets since it became clear that Covid-19 would not be limited to China has boldly highlighted this.Suppressing the epidemic, but allowing the economy to still function, requires key decisions, in which central banks and finance ministries play a part.The role of fiscal and monetary authorities in managing an epidemic economyThe scope to use monetary policy to manage the economic impact of Covid-19 is limited. The fact that the underlying cause of the shock is an infectious disease outbreak (rather than a banking crisis, as in 2008-09) and nominal interest rates are currently close to zero in most major advanced economies reduces the effectiveness of monetary policy.Since 2010, reductions in fiscal deficits mean there is more scope for supportive fiscal action. But even here, high public debt levels and the desire not to underwrite ‘zombie’ companies that may have been sustained by a decade of ultra-low interest rates remain constraints. However, outside broad based fiscal and monetary policies there are six ways in which finance ministries and central banks will play a critical role in responding to the crisis.A first crucial role for finance ministries and central banks is in helping provide the best possible economic evaluation of strict containment measures (trying to isolate each potential case) versus managing the epidemic (delaying the spread of the virus, protecting the most vulnerable and treating the sick, while enabling the majority of people to get on with daily life). Given the economic consequences, they must play a full part, alongside health experts, in advising political leaders on this key decision.Second, if large numbers of staff are required to work from home to manage the epidemic, they have the lead role in doing whatever is necessary to ensure that financial markets – and thus the wider economy – will continue to function smoothly.Third, they need to ensure adequate funding for the public health response. Steps that can make an enormous difference to the success of containment strategies, such as strengthening surveillance, and guaranteeing the availability of testing kits and protective equipment for front line health workers, must not fail because of a lack of funding. Fourth, they have a lead role in designing targeted economic interventions for the wider economy. Some of these are needed immediately to re-enforce and incentivize strict containment strategies, such as ensuring that employees without full or adequate sick leave cover have the financial support to enable them to report and self-isolate when they get sick. Other interventions may help improve the resilience of the economy in accommodating moderate ‘social distancing’ measures; for example, by providing assistance to small firms to help them gear up for home working.Yet others are needed, as a contingency, to safeguard the most vulnerable sectors (such as tourism, retail and transport) in circumstances where there is a prolonged downturn. The latter may include schemes to allow deferral of tax payments by SMEs, or steps to encourage loan extensions and other forms of liquidity support from the banking system, or by moves to underwrite continued provision of business insurance.Fifth, national economic authorities will need to play their part in combatting ‘fake news’ through providing transparent and high-quality analysis. This includes providing forecasts on the likely economic impact of the virus under different scenarios, but also detailed information on the support and contingency measures they are considering, so they can be improved and refined through feedback. Sixth, they will need to ensure that there is generous international support for poor countries, by ensuring the available multilateral support facilities from the international financial institutions and multilateral development banks are adequately funded and fit for purpose. The World Bank has already announced an initial $12 billion financing package, but much more is likely to be needed.They also need to support coordinated bilateral aid where this is more effective, as well as special measures to support particularly vulnerable groups, for example, in refugee camps and prisons. Given the importance of distributing sophisticated medical equipment and expertise quickly, it is also important that every effort is made to avoid delays due to customs and migration checks.Managing the futureThe response to the immediate crisis will rightly take priority now, but economic authorities must also play their part in ensuring the world finally takes decisive steps to prevent a repeat of Covid-19 in future.The experience with SARS, H1N1 and Ebola shows that, while some progress is made after each outbreak, this is often not sustained. This epidemic shows that managing diseases is absolutely critical to the long-term health of global economy, and doubly so in circumstances where traditional central bank and finance ministry tools for dealing with major global economic shocks are limited.Finance ministries and central banks therefore need to push hard within government to ensure sustained long-term funding of research on prevention and strengthening of public health systems. They also need to ensure that the right lessons are drawn by the private sector on making international supply chains more robust.Critical to the overall success of the economic effort will be effective international coordination. The G20 was established as the premier economic forum for international economic cooperation in 2010, and global health issues have been a substantive part of the G20 agenda since the 2017 Hamburg Summit. At the same time, G7 finance ministers and deputies remain one of the most effective bodies for managing economic crises on a day-to-day basis and should continue this within the framework provided by the G20.However, to be effective, the US, as current president of the G7, will need to put aside its reservations on multilateral economic cooperation and working with China to provide strong leadership.

allo Crystallographic and kinetic analyses of the FdsBG subcomplex of the cytosolic formate dehydrogenase FdsABG from Cupriavidus necator [Molecular Biophysics] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Formate oxidation to carbon dioxide is a key reaction in one-carbon compound metabolism, and its reverse reaction represents the first step in carbon assimilation in the acetogenic and methanogenic branches of many anaerobic organisms. The molybdenum-containing dehydrogenase FdsABG is a soluble NAD+-dependent formate dehydrogenase and a member of the NADH dehydrogenase superfamily. Here, we present the first structure of the FdsBG subcomplex of the cytosolic FdsABG formate dehydrogenase from the hydrogen-oxidizing bacterium Cupriavidus necator H16 both with and without bound NADH. The structures revealed that the two iron-sulfur clusters, Fe4S4 in FdsB and Fe2S2 in FdsG, are closer to the FMN than they are in other NADH dehydrogenases. Rapid kinetic studies and EPR measurements of rapid freeze-quenched samples of the NADH reduction of FdsBG identified a neutral flavin semiquinone, FMNH•, not previously observed to participate in NADH-mediated reduction of the FdsABG holoenzyme. We found that this semiquinone forms through the transfer of one electron from the fully reduced FMNH−, initially formed via NADH-mediated reduction, to the Fe2S2 cluster. This Fe2S2 cluster is not part of the on-path chain of iron-sulfur clusters connecting the FMN of FdsB with the active-site molybdenum center of FdsA. According to the NADH-bound structure, the nicotinamide ring stacks onto the re-face of the FMN. However, NADH binding significantly reduced the electron density for the isoalloxazine ring of FMN and induced a conformational change in residues of the FMN-binding pocket that display peptide-bond flipping upon NAD+ binding in proper NADH dehydrogenases.

allo A single amino acid substitution uncouples catalysis and allostery in an essential biosynthetic enzyme in Mycobacterium tuberculosis [Enzymology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Allostery exploits the conformational dynamics of enzymes by triggering a shift in population ensembles toward functionally distinct conformational or dynamic states. Allostery extensively regulates the activities of key enzymes within biosynthetic pathways to meet metabolic demand for their end products. Here, we have examined a critical enzyme, 3-deoxy-d-arabino-heptulosonate 7-phosphate synthase (DAH7PS), at the gateway to aromatic amino acid biosynthesis in Mycobacterium tuberculosis, which shows extremely complex dynamic allostery: three distinct aromatic amino acids jointly communicate occupancy to the active site via subtle changes in dynamics, enabling exquisite fine-tuning of delivery of these essential metabolites. Furthermore, this allosteric mechanism is co-opted by pathway branchpoint enzyme chorismate mutase upon complex formation. In this study, using statistical coupling analysis, site-directed mutagenesis, isothermal calorimetry, small-angle X-ray scattering, and X-ray crystallography analyses, we have pinpointed a critical node within the complex dynamic communication network responsible for this sophisticated allosteric machinery. Through a facile Gly to Pro substitution, we have altered backbone dynamics, completely severing the allosteric signal yet remarkably, generating a nonallosteric enzyme that retains full catalytic activity. We also identified a second residue of prime importance to the inter-enzyme communication with chorismate mutase. Our results reveal that highly complex dynamic allostery is surprisingly vulnerable and provide further insights into the intimate link between catalysis and allostery. Full Article

Zoubir Senior Professor of International Studies, KEDGE Business School; Visiting Fellow, Brookings Doha Center Coronavirus is a godsend for Algeria’s government to introduce restrictive measures beyond those needed to contain COVID-19. But its new leaders are missing a chance to gain legitimacy, which will offset the socio-economic fallout of the drop in oil prices. 2020-05-06-Algeria-Health-Covid Algerian volunteers prepare personal protection equipment (PPE) to help combat the coronavirus epidemic in the capital Algiers. Photo by RYAD KRAMDI/AFP via Getty Images. Although protests successfully ended Abdelaziz Bouteflika’s 20-year sultanistic rule a little over one year ago, demands have been continuing to dismantle the system, get rid of the old personnel, and institute democracy.The controversial election in December of Abdelmadjid Tebboune — who has inherited a disastrous situation — has not tempered the determination of the Hirak protest movement. As a former minister and prime minister under Bouteflika, the new president has won little legitimacy, and protests have continued.Now COVID-19 is worsening already dire economic conditions, such as a sharp drop in oil prices. By the beginning of May, statistics showed 10% of confirmed cases have ended in fatality, the highest percentage in the region.Maintaining an authoritarian styleHirak had already called for the suspension of the marches — mobilising online instead — before the government’s measures, which include curfews and lockdowns, demonstrating a high sense of duty. But instead of appeasing Hirak’s demands, the government has maintained the authoritarian style of its predecessors.Tebboune released more than 5,000 prisoners on March 31 but kept prisoners of conscience and leaders of the hirak imprisoned, then subsequently imprisoned journalists and activists. It even passed a controversial penal law, that also covers fake news, and may be used to justify actions against journalists.The regime wishes to see an end to the Hirak, and rejects accusations of totalitarianism by insisting freedom and a democratic climate exist in Algeria.Tebboune’s actions contradict his praise for the ‘blessed’ hirak and his promises of instituting the rule of law. In proclaiming the measures, the government has shown disappointing leadership, acting in an authoritarian fashion.Tebboune also declared proudly that Algeria was fully prepared to fight the coronavirus epidemic, an optimistic claim given the country has only 400 intensive care unit (ICU) beds, or one per 100,000 people. Despite hundreds of billions of hydrocarbon dollars accumulating during the Bouteflika-era, Algeria’s health system ranks 173 out of 195 countries.Algerians often refer to hospitals as ‘mouroirs’, meaning ‘places for the dying’. Not only has the state failed to build modern hospitals but basic hygienic conditions are lacking, and government officials prefer being treated overseas. A 2014 project to build five university hospitals was abandoned, leaving the health sector in deplorable shape.Before Chinese assistance arrived, the glaring lack of equipment to protect caregivers and care for the sick was evident. Prime Minister Abdelaziz Djerad admitted the health system required a ‘total overhaul’. The president recently stated Algeria’s doctors are among the 'best in the world' but didn't address why almost 15,000 Algerian doctors practice in France.Strict containment measures are in sync with most countries but implementation is challenging when most people live in overcrowded urban dwellings (the average household consists of 5.9 members).Water shortages in many areas makes good hygiene and decontamination impossible, while schools and universities find online teaching difficult when many students do not possess laptops or internet connections. And only 20% of Algerians have debit cards in a cash-dominated economy because of low trust in the public-dominated banking sector, making online shopping capability low.An already declining macroeconomic situation is worsening due to COVID-19. The IMF revised its 2020 estimates for Algeria, forecasting a catastrophic contraction of -5.2% in a country where hydrocarbons account for 93% of export revenues and 60% of its budget.Foreign currency reserves are now an estimated $55 billion (expected to fall to $44billion by the end of 2020), down from $200 billion in 2014, and Algerian crude has recently traded close to production costs, with the fiscal breakeven oil price at $157.In line with its historic aversion to external borrowing, Tebboune recently ruled out seeking financial support from the ‘IMF or other foreign banks’, as he argued such borrowing undermines sovereign foreign policy because - when indebted - ‘we cannot talk about either Palestine or Western Sahara’, two causes dear to Algeria. ‘Friendly countries’ - most likely a reference to China - are said to have offered to grant loans which have been declined for now.The government is forecasted to face a 20% budget shortfall this year, but Algeria’s fiscal response to COVID-19 is actually the largest among the regional hydrocarbon exporters at an estimated 8% of GDP, compared to an average of 3.2%. However, the government revised downwards its 2020 public spending by 50% (a second cut in a month, from an initial 30% reduction), halting state projects and slashing its $41 billion import bill by 25% while expanding agricultural production. National oil company SONATRACH will also cut planned investment by half to $7 billion but plans have been revealed to develop other natural resources including gold, uranium and phosphates.But recent growth rates are insufficient to create jobs for those entering the labour market. Despite government attempts to support a rather anaemic ‘formal’ private sector, estimates are 700,000 jobs could be lost due to potential bankruptcies from reduced activity and a loss of markets abroad.Facing potential social unrest and the quasi-preservation of a tired social contract, the government has committed to upholding public sector wages - including for 50% of the civil servants told to stay home - protecting sacrosanct, unsustainable subsidies, and increasing health expenditure to strengthen the capacity to combat COVID-19.A supplementary finance law will include various measures that support businesses and the economic fallout. However, while the government is to be commended for its efforts to aid businesses, supporting large swathes of the population is challenging as approximately 50% of the workforce operate in the informal economy.Weak administrative capacity and insufficient data to implement cash transfers makes the planned ‘solidarity allowance’ of 10,000 dinars ($80) for Ramadan difficult to allocate to those who most need it (especially those in the informal sector). Families, communities, and religious organisations continue to be a social safety net.So COVID-19 has not created new problems, it has merely magnified and exacerbated the numerous inequalities and failures of the Bouteflika regime to sufficiently invest in human security (economic, food, health environmental, personal, community, and political). Typically, whenever oil prices and related earnings dwindle, the political system promises to reform and diversify the economy. Tebboune is repeating this same old tune.There are positive elements, such as the government’s realization it must initiate genuine reforms. And local enterprises have been successfully producing artificial respirators, surgical masks, and other materials. Algerians, including the Hirak, are showing great social solidarity.But the government must capitalize on these positive actions by introducing real change. Because, if not, Hirak will certainly be back in force once the crisis is over, and operating in an environment of worsening socioeconomic problems. The medicine of the past will not work.

This Fe2S2 cluster is not part of the on-path chain of iron-sulfur clusters connecting the FMN of FdsB with the active-site molybdenum center of FdsA. According to the NADH-bound structure, the nicotinamide ring stacks onto the re-face of the FMN. However, NADH binding significantly reduced the electron density for the isoalloxazine ring of FMN and induced a conformational change in residues of the FMN-binding pocket that display peptide-bond flipping upon NAD+ binding in proper NADH dehydrogenases.

allo 60k workers received allowance By www.news.gov.hk Published On :: Mon, 04 May 2020 00:00:00 +0800 Some 60,000 workers of over 340 contractors received the first round of allowance under the Anti-epidemic Fund, the Government said today. The Government explained that it has been making use of the fund to provide allowances to eligible cleansing and security workers engaged by service contractors of the Government and Housing Authority. Front-line cleansing workers, toilet attendants and security workers employed by the service contractors can receive a monthly allowance of $1,000 for a period of no fewer than four months throughout the epidemic period. The first round of funding amounted to some $60 million. Eligible workers who performed duties in March have received the $1,000 allowance applicable to that month. Arrangements were made for the April allowance to be issued concurrently with the salary of that month. Front-line workers are not required to submit any application for the allowance. The departments and the Housing Authority entered into agreements with their contractors to ensure the transfer of the allowance to eligible workers. The Government said the allowance aims to provide financial support to cleansing and security staff engaged by service contractors in anti-epidemic efforts, and gives recognition for their committed services at this critical juncture.

allo How to Fight the Economic Fallout From the Coronavirus By feedproxy.google.com Published On :: Wed, 04 Mar 2020 03:56:03 +0000 4 March 2020 Creon Butler Research Director, Trade, Investment & New Governance Models: Director, Global Economy and Finance Programme LinkedIn Finance ministries and central banks have a critical role to play to mitigate the threat Covid-19 poses to the global economy. 2020-03-03-TokyoCV.jpg A pedestrian wearing a face mask walks past stock prices in Tokyo on 25 February. Photo: Getty Images. Epidemics, of the size of Covid-19, have huge economic impacts – not just from the costs of managing the health of people, but stopping them, and keeping the economy working. The 10% fall in global stock markets since it became clear that Covid-19 would not be limited to China has boldly highlighted this.Suppressing the epidemic, but allowing the economy to still function, requires key decisions, in which central banks and finance ministries play a part.The role of fiscal and monetary authorities in managing an epidemic economyThe scope to use monetary policy to manage the economic impact of Covid-19 is limited. The fact that the underlying cause of the shock is an infectious disease outbreak (rather than a banking crisis, as in 2008-09) and nominal interest rates are currently close to zero in most major advanced economies reduces the effectiveness of monetary policy.Since 2010, reductions in fiscal deficits mean there is more scope for supportive fiscal action. But even here, high public debt levels and the desire not to underwrite ‘zombie’ companies that may have been sustained by a decade of ultra-low interest rates remain constraints. However, outside broad based fiscal and monetary policies there are six ways in which finance ministries and central banks will play a critical role in responding to the crisis.A first crucial role for finance ministries and central banks is in helping provide the best possible economic evaluation of strict containment measures (trying to isolate each potential case) versus managing the epidemic (delaying the spread of the virus, protecting the most vulnerable and treating the sick, while enabling the majority of people to get on with daily life). Given the economic consequences, they must play a full part, alongside health experts, in advising political leaders on this key decision.Second, if large numbers of staff are required to work from home to manage the epidemic, they have the lead role in doing whatever is necessary to ensure that financial markets – and thus the wider economy – will continue to function smoothly.Third, they need to ensure adequate funding for the public health response. Steps that can make an enormous difference to the success of containment strategies, such as strengthening surveillance, and guaranteeing the availability of testing kits and protective equipment for front line health workers, must not fail because of a lack of funding. Fourth, they have a lead role in designing targeted economic interventions for the wider economy. Some of these are needed immediately to re-enforce and incentivize strict containment strategies, such as ensuring that employees without full or adequate sick leave cover have the financial support to enable them to report and self-isolate when they get sick. Other interventions may help improve the resilience of the economy in accommodating moderate ‘social distancing’ measures; for example, by providing assistance to small firms to help them gear up for home working.Yet others are needed, as a contingency, to safeguard the most vulnerable sectors (such as tourism, retail and transport) in circumstances where there is a prolonged downturn. The latter may include schemes to allow deferral of tax payments by SMEs, or steps to encourage loan extensions and other forms of liquidity support from the banking system, or by moves to underwrite continued provision of business insurance.Fifth, national economic authorities will need to play their part in combatting ‘fake news’ through providing transparent and high-quality analysis. This includes providing forecasts on the likely economic impact of the virus under different scenarios, but also detailed information on the support and contingency measures they are considering, so they can be improved and refined through feedback. Sixth, they will need to ensure that there is generous international support for poor countries, by ensuring the available multilateral support facilities from the international financial institutions and multilateral development banks are adequately funded and fit for purpose. The World Bank has already announced an initial $12 billion financing package, but much more is likely to be needed.They also need to support coordinated bilateral aid where this is more effective, as well as special measures to support particularly vulnerable groups, for example, in refugee camps and prisons. Given the importance of distributing sophisticated medical equipment and expertise quickly, it is also important that every effort is made to avoid delays due to customs and migration checks.Managing the futureThe response to the immediate crisis will rightly take priority now, but economic authorities must also play their part in ensuring the world finally takes decisive steps to prevent a repeat of Covid-19 in future.The experience with SARS, H1N1 and Ebola shows that, while some progress is made after each outbreak, this is often not sustained. This epidemic shows that managing diseases is absolutely critical to the long-term health of global economy, and doubly so in circumstances where traditional central bank and finance ministry tools for dealing with major global economic shocks are limited.Finance ministries and central banks therefore need to push hard within government to ensure sustained long-term funding of research on prevention and strengthening of public health systems. They also need to ensure that the right lessons are drawn by the private sector on making international supply chains more robust.Critical to the overall success of the economic effort will be effective international coordination. The G20 was established as the premier economic forum for international economic cooperation in 2010, and global health issues have been a substantive part of the G20 agenda since the 2017 Hamburg Summit. At the same time, G7 finance ministers and deputies remain one of the most effective bodies for managing economic crises on a day-to-day basis and should continue this within the framework provided by the G20.However, to be effective, the US, as current president of the G7, will need to put aside its reservations on multilateral economic cooperation and working with China to provide strong leadership.

allo Algeria’s Perfect Storm: COVID-19 and Its Fallout By feedproxy.google.com Published On :: Wed, 06 May 2020 19:19:54 +0000 6 May 2020 Adel Hamaizia Associate Fellow, Middle East and North Africa Programme Yahia H. Zoubir Senior Professor of International Studies, KEDGE Business School; Visiting Fellow, Brookings Doha Center Coronavirus is a godsend for Algeria’s government to introduce restrictive measures beyond those needed to contain COVID-19. But its new leaders are missing a chance to gain legitimacy, which will offset the socio-economic fallout of the drop in oil prices. 2020-05-06-Algeria-Health-Covid Algerian volunteers prepare personal protection equipment (PPE) to help combat the coronavirus epidemic in the capital Algiers. Photo by RYAD KRAMDI/AFP via Getty Images. Although protests successfully ended Abdelaziz Bouteflika’s 20-year sultanistic rule a little over one year ago, demands have been continuing to dismantle the system, get rid of the old personnel, and institute democracy.The controversial election in December of Abdelmadjid Tebboune — who has inherited a disastrous situation — has not tempered the determination of the Hirak protest movement. As a former minister and prime minister under Bouteflika, the new president has won little legitimacy, and protests have continued.Now COVID-19 is worsening already dire economic conditions, such as a sharp drop in oil prices. By the beginning of May, statistics showed 10% of confirmed cases have ended in fatality, the highest percentage in the region.Maintaining an authoritarian styleHirak had already called for the suspension of the marches — mobilising online instead — before the government’s measures, which include curfews and lockdowns, demonstrating a high sense of duty. But instead of appeasing Hirak’s demands, the government has maintained the authoritarian style of its predecessors.Tebboune released more than 5,000 prisoners on March 31 but kept prisoners of conscience and leaders of the hirak imprisoned, then subsequently imprisoned journalists and activists. It even passed a controversial penal law, that also covers fake news, and may be used to justify actions against journalists.The regime wishes to see an end to the Hirak, and rejects accusations of totalitarianism by insisting freedom and a democratic climate exist in Algeria.Tebboune’s actions contradict his praise for the ‘blessed’ hirak and his promises of instituting the rule of law. In proclaiming the measures, the government has shown disappointing leadership, acting in an authoritarian fashion.Tebboune also declared proudly that Algeria was fully prepared to fight the coronavirus epidemic, an optimistic claim given the country has only 400 intensive care unit (ICU) beds, or one per 100,000 people. Despite hundreds of billions of hydrocarbon dollars accumulating during the Bouteflika-era, Algeria’s health system ranks 173 out of 195 countries.Algerians often refer to hospitals as ‘mouroirs’, meaning ‘places for the dying’. Not only has the state failed to build modern hospitals but basic hygienic conditions are lacking, and government officials prefer being treated overseas. A 2014 project to build five university hospitals was abandoned, leaving the health sector in deplorable shape.Before Chinese assistance arrived, the glaring lack of equipment to protect caregivers and care for the sick was evident. Prime Minister Abdelaziz Djerad admitted the health system required a ‘total overhaul’. The president recently stated Algeria’s doctors are among the 'best in the world' but didn't address why almost 15,000 Algerian doctors practice in France.Strict containment measures are in sync with most countries but implementation is challenging when most people live in overcrowded urban dwellings (the average household consists of 5.9 members).Water shortages in many areas makes good hygiene and decontamination impossible, while schools and universities find online teaching difficult when many students do not possess laptops or internet connections. And only 20% of Algerians have debit cards in a cash-dominated economy because of low trust in the public-dominated banking sector, making online shopping capability low.An already declining macroeconomic situation is worsening due to COVID-19. The IMF revised its 2020 estimates for Algeria, forecasting a catastrophic contraction of -5.2% in a country where hydrocarbons account for 93% of export revenues and 60% of its budget.Foreign currency reserves are now an estimated $55 billion (expected to fall to $44billion by the end of 2020), down from $200 billion in 2014, and Algerian crude has recently traded close to production costs, with the fiscal breakeven oil price at $157.In line with its historic aversion to external borrowing, Tebboune recently ruled out seeking financial support from the ‘IMF or other foreign banks’, as he argued such borrowing undermines sovereign foreign policy because - when indebted - ‘we cannot talk about either Palestine or Western Sahara’, two causes dear to Algeria. ‘Friendly countries’ - most likely a reference to China - are said to have offered to grant loans which have been declined for now.The government is forecasted to face a 20% budget shortfall this year, but Algeria’s fiscal response to COVID-19 is actually the largest among the regional hydrocarbon exporters at an estimated 8% of GDP, compared to an average of 3.2%. However, the government revised downwards its 2020 public spending by 50% (a second cut in a month, from an initial 30% reduction), halting state projects and slashing its $41 billion import bill by 25% while expanding agricultural production. National oil company SONATRACH will also cut planned investment by half to $7 billion but plans have been revealed to develop other natural resources including gold, uranium and phosphates.But recent growth rates are insufficient to create jobs for those entering the labour market. Despite government attempts to support a rather anaemic ‘formal’ private sector, estimates are 700,000 jobs could be lost due to potential bankruptcies from reduced activity and a loss of markets abroad.Facing potential social unrest and the quasi-preservation of a tired social contract, the government has committed to upholding public sector wages - including for 50% of the civil servants told to stay home - protecting sacrosanct, unsustainable subsidies, and increasing health expenditure to strengthen the capacity to combat COVID-19.A supplementary finance law will include various measures that support businesses and the economic fallout. However, while the government is to be commended for its efforts to aid businesses, supporting large swathes of the population is challenging as approximately 50% of the workforce operate in the informal economy.Weak administrative capacity and insufficient data to implement cash transfers makes the planned ‘solidarity allowance’ of 10,000 dinars ($80) for Ramadan difficult to allocate to those who most need it (especially those in the informal sector). Families, communities, and religious organisations continue to be a social safety net.So COVID-19 has not created new problems, it has merely magnified and exacerbated the numerous inequalities and failures of the Bouteflika regime to sufficiently invest in human security (economic, food, health environmental, personal, community, and political). Typically, whenever oil prices and related earnings dwindle, the political system promises to reform and diversify the economy. Tebboune is repeating this same old tune.There are positive elements, such as the government’s realization it must initiate genuine reforms. And local enterprises have been successfully producing artificial respirators, surgical masks, and other materials. Algerians, including the Hirak, are showing great social solidarity.But the government must capitalize on these positive actions by introducing real change. Because, if not, Hirak will certainly be back in force once the crisis is over, and operating in an environment of worsening socioeconomic problems. The medicine of the past will not work.

allo Metallopeptidase Stp1 activates the transcription factor Sre1 in the carotenogenic yeast Xanthophyllomyces dendrorhous [Research Articles] By feedproxy.google.com Published On :: 2020-02-01T00:05:23-08:00 Xanthophyllomyces dendrorhous is a basidiomycete yeast known as a natural producer of astaxanthin, a carotenoid of commercial interest because of its antioxidant properties. Recent studies indicated that X. dendrorhous has a functional SREBP pathway involved in the regulation of isoprenoid compound biosynthesis, which includes ergosterol and carotenoids. SREBP is a major regulator of sterol metabolism and homeostasis in mammals; characterization in fungi also provides information about its role in the hypoxia adaptation response and virulence. SREBP protease processing is required to activate SREBP pathway functions in fungi. Here, we identified and described the STP1 gene, which encodes a metallopeptidase of the M50 family involved in the proteolytic activation of the transcription factor Sre1 of the SREBP pathway, in X. dendrorhous. We assessed STP1 function in stp1 strains derived from the wild-type and a mutant of ergosterol biosynthesis that overproduces carotenoids and sterols. Bioinformatic analysis of the deduced protein predicted the presence of characteristic features identified in homologs from mammals and fungi. The stp1 mutation decreased yeast growth in the presence of azole drugs and reduced transcript levels of Sre1-dependent genes. This mutation also negatively affected the carotenoid- and sterol-overproducing phenotype. Western blot analysis demonstrated that Sre1 was activated in the yeast ergosterol biosynthesis mutant and that the stp1 mutation introduced in this strain prevented Sre1 proteolytic activation. Overall, our results demonstrate that STP1 encodes a metallopeptidase involved in proteolytic activation of Sre1 in X. dendrorhous, contributing to our understanding of fungal SREBP pathways.

allo Low Dose IL-2 Combined with Rapamycin Led to an Expansion of CD4+CD25+FOXP3+ Tregs and Prolonged Human Islet-allograft Survival in Humanized Mice By diabetes.diabetesjournals.org Published On :: 2020-05-07T07:53:04-07:00 Islet transplantation is an emerging therapy for type 1 diabetes (T1D) and hypoglycaemic unawareness. However, a key challenge for islet transplantation is cellular rejection and the requirement for long-term immunosuppression. In this study we established a diabetic-humanized NOD-scidIL2Rnull(NSG) mouse model of T cell mediated human islet-allograft rejection and developed a therapeutic regimen of low-dose recombinant human interleukin2(IL-2) combined with low-dose rapamycin to prolong graft survival. NSG-mice that had received renal-subcapsular human islet-allografts and were transfused with 1x107 of human-spleen-mononuclear-cells (hSPMCs), reconstituted human CD45+ cells that were predominantly CD3+ T cells and rejected their grafts with a median survival time of 27 days. IL-2 alone (0.3x106 IU/m2 or 1x106 IU/m2), or rapamycin alone (0.5-1mg/kg) for 3 weeks did not prolong survival. However, the combination of rapamycin with IL-2 for 3 weeks significantly prolonged human islet-allograft survival. Graft survival was associated with expansion of CD4+CD25+FOXP3+ Tregs and enhanced TGF-β production by CD4+ T cells. CD8+ T cells showed reduced IFN- production and reduced expression of perforin-1. The combination of IL-2 and rapamycin has the potential to inhibit human islet-allograft rejection by expanding CD4+FOXP3+ Tregs in vivo and supressing effector cell function, and could be the basis of effective tolerance-based regimens.
