ess Quantification of PD-L1 expression with [18F]BMS-986192 PET/CT in patients with advanced stage non-small-cell lung cancer By jnm.snmjournals.org Published On :: 2020-02-14T14:01:21-08:00 The aim of this work was to quantify the uptake of [18F]BMS-986192, a PD-L1 adnectin PET tracer, in patients with non-small-cell lung cancer (NSCLC). To this end, plasma input kinetic modeling of dynamic tumor uptake data with online arterial blood sampling was performed. In addition, the accuracy of simplified uptake metrics such as standardized uptake value (SUV) was investigated. Methods: Data from a study with [18F]BMS-986192 in patients with advanced stage NSCLC eligible for nivolumab treatment were used if a dynamic scan was available and lesions were present in the field of view of the dynamic scan. After injection of [18F]BMS-986192, a 60-minutes dynamic PET-CT scan was started, followed by a 30-min whole body PET-CT scan. Continuous arterial and discrete arterial and venous blood sampling were performed to determine a plasma input function. Tumor time activity curves were fitted by several plasma input kinetic models. Simplified uptake parameters included tumor to blood ratio as well as several SUV measures. Results: Twenty two tumors in nine patients were analyzed. The arterial plasma input single-tissue reversible compartment model with fitted blood volume fraction seems to be the most preferred model as it best fitted 11 out of 18 tumor time activity curves. The distribution volume VT ranged from 0.4 to 4.8 mL·cm-3. Similar values were obtained with an image derived input function. From the simplified measures, SUV normalized for body weight (SUVBW) at 50 and 67 minutes post injection correlated best with VT, with an R2 > 0.9. Conclusion: A single tissue reversible model can be used for the quantification of tumor uptake of the PD-L1 PET tracer [18F]BMS-986192. SUVBW at 60 minutes post injection, normalized for body weight, is an accurate simplified parameter for uptake assessment of baseline studies. In order to assess its predictive value for response evaluation during PD-(L)1 immune checkpoint inhibition further validation of SUV against VT based on an image derived input function is recommended.

ess 64Cu-DOTATATE PET/CT and prediction of overall and progression-free survival in patients with neuroendocrine neoplasms By jnm.snmjournals.org Published On :: 2020-02-28T13:52:17-08:00 Overexpression of somatostatin receptors in patients with neuroendocrine neoplasms (NEN) is utilized for both diagnosis and treatment. Receptor density may reflect tumor differentiation and thus be associated with prognosis. Non-invasive visualization and quantification of somatostatin receptor density is possible by somatostatin receptor imaging (SRI) using positron emission tomography (PET). Recently, we introduced 64Cu-DOTATATE for SRI and we hypothesized that uptake of this tracer could be associated with overall (OS) and progression-free survival (PFS). Methods: We evaluated patients with NEN that had a 64Cu-DOTATATE PET/CT SRI performed in two prospective studies. Tracer uptake was determined as the maximal standardized uptake value (SUVmax) for each patient. Kaplan-Meier analysis with log-rank was used to determine the predictive value of 64Cu-DOTATATE SUVmax for OS and PFS. Specificity, sensitivity and accuracy was calculated for prediction of outcome at 24 months after 64Cu-DOTATATE PET/CT. Results: A total of 128 patients with NEN were included and followed for a median of 73 (1-112) months. During follow-up, 112 experienced disease progression and 69 patients died. The optimal cutoff for 64Cu-DOTATATE SUVmax was 43.3 for prediction of PFS with a hazard ratio of 0.56 (95% CI: 0.38-0.84) for patients with SUVmax > 43.3. However, no significant cutoff was found for prediction of OS. In multiple Cox regression adjusted for age, sex, primary tumor site and tumor grade, the SUVmax cutoff hazard ratio was 0.50 (0.32-0.77) for PFS. The accuracy was moderate for predicting PFS (57%) at 24 months after 64Cu-DOTATATE PET/CT. Conclusion: In this first study to report the association of 64Cu-DOTATATE PET/CT and outcome in patients with NEN, tumor somatostatin receptor density visualized with 64Cu-DOTATATE PET/CT was prognostic for PFS but not OS. However, the accuracy of prediction of PFS at 24 months after 64Cu-DOTATATE PET/CT SRI was moderate limiting the value on an individual patient basis. Full Article
ess OpenDose: open access resources for nuclear medicine dosimetry By jnm.snmjournals.org Published On :: 2020-03-13T14:12:30-07:00 Background: Radiopharmaceutical dosimetry depends on the localization in space and time of radioactive sources and requires the estimation of the amount of energy emitted by the sources deposited within targets. In particular, when computing resources are not accessible, this task can be carried out using precomputed tables of Specific Absorbed Fractions (SAFs) or S values based on dosimetric models. The OpenDose collaboration aims to generate and make freely available a range of dosimetric data and tools. Methods: OpenDose brings together resources and expertise from 18 international teams to produce and compare traceable dosimetric data using 6 of the most popular Monte Carlo codes in radiation transport (EGSnrc/EGS++, FLUKA, GATE, Geant4, MCNP/MCNPX and PENELOPE). SAFs are uploaded, together with their associated statistical uncertainties, in a relational database. S values are then calculated from mono-energetic SAFs, based on the radioisotope decay data presented in the International Commission on Radiological Protection (ICRP) publication 107. Results: The OpenDose collaboration produced SAFs for all source regions and targets combinations of the two ICRP 110 adult reference models. SAFs computed from the different Monte Carlo codes were in good agreement at all energies, with standard deviations below individual statistical uncertainties. Calculated S values were in good agreement with OLINDA 2 (commercial) and IDAC 2.1 (free) software. A dedicated website (www.opendose.org) has been developed to provide easy and open access to all data. Conclusion: The OpenDose website allows the display and download of SAFs and the corresponding S values for 1252 radionuclides. The OpenDose collaboration, open to new research teams, will extend data production to other dosimetric models and implement new free features, such as online dosimetric tools and patient-specific absorbed dose calculation software, together with educational resources.

ess FDG-PET assessment of malignant pleural mesothelioma: Total Lesion volume and Total Lesion Glycolysis; the central role of volume. By jnm.snmjournals.org Published On :: 2020-04-13T14:09:24-07:00 Cancer Survival is related to tumor volume. FDG PET measurement of tumor volume holds promise but is not yet a clinical tool. Measurements come in two forms: the total lesion volume (TLV) based on the number of voxels in the tumor and secondly the total lesion glycolysis (TLG) which is the TLV multiplied by the average SUL per voxel of the tumor (SUL is the standardize uptake value normalized for lean mass). In this study we measured tumor volume in patients with malignant pleural mesothelioma (MPM). METHODS: A threshold-based program in IDL was developed to measure tumor volume in FDG PET images. 19 patients with malignant pleural mesothelioma (MPM) were studied before and after two cycles (6 weeks) of chemo-immunotherapy. Measurements included the total lesion volume (TLV), Total Lesion Glycolysis (TLG), the sum of the SULs in the tumor (SUL- total), a measure of total FDG uptake, and the average SUL per voxel. RESULTS: Baseline MPM volumes (TLV) ranged from 11 to 2610 cc. TLG values ranged from 32 to 8552 SUL-cc and were strongly correlated with TLV. While tumor volumes ranged over 3 orders of magnitude, the average SUL per voxel, SUL-average, stayed within a narrow range of 2.4 to 5.3 units. Thus, TLV was the major component of TLG while SUL-average was a minor component and was essentially constant. Further evaluation of SUL-average showed that in this cohort it’s two components SUL-total and tumor volume changed in parallel and were strongly correlated, r= 0.99, p<.01. Thus, whether the tumors were large or small, the FDG uptake as measured by SUL-total was proportional to the total tumor volume. Conclusion: TLG equals TLV multiplied by the average SUL per voxel, essentially TLV multiplied by a constant. Thus TLG, commonly considered a measure of "metabolic activity" in tumors, is also in this cohort a measure of tumor volume. The constancy of SUL per voxel is due to FDG uptake being proportional to tumor volume. Thus, in this study, the FDG uptake was also a measure of volume. Full Article
ess Assessing the Activity of Multidrug Resistance-Associated Protein 1 at the Lung Epithelial Barrier By jnm.snmjournals.org Published On :: 2020-04-13T14:09:24-07:00 Multidrug resistance-associated protein 1 (ABCC1) is abundantly expressed at the lung epithelial barrier, where it may influence the pulmonary disposition of inhaled drugs and contribute to variability in therapeutic response. Aim of this study was to assess the impact of ABCC1 on the pulmonary disposition of 6-bromo-7-11C-methylpurine (11C-BMP), a prodrug radiotracer which is intracellularly conjugated with glutathione to form the ABCC1 substrate S-(6-(7-11C-methylpurinyl))glutathione (11C-MPG). Methods: Groups of Abcc1(-/-) rats, wild-type rats pretreated with the ABCC1 inhibitor MK571 and wild-type control rats underwent dynamic PET scans after administration of 11C-BMP intravenously (i.v.) or by intratracheal aerosolization (i.t.). In vitro transport experiments were performed with unlabeled BMP in the human distal lung epithelial cell line NCI-H441. Results: Pulmonary kinetics of radioactivity were significantly different between wild-type and Abcc1(-/-) rats, but differences were more pronounced after i.t. than after i.v. administration. After i.v. administration lung exposure (AUClung) was 77% higher and the elimination slope of radioactivity washout from the lungs (kE,lung) was 70% lower, whereas after i.t. administration AUClung was 352% higher and kE,lung was 86% lower in Abcc1(-/-) rats. Pretreatment with MK571 decreased kE,lung by 20% after i.t. radiotracer administration. Intracellular accumulation of MPG in NCI-H441 cells was significantly higher and extracellular efflux was lower in presence than in absence of MK571. Conclusion: PET with pulmonary administered 11C-BMP can measure ABCC1 activity at the lung epithelial barrier and may be applicable in humans to assess the effects of disease, genetic polymorphisms or concomitant drug intake on pulmonary ABCC1 activity.

ess Molecular imaging of PD-L1 expression and dynamics with the adnectin-based PET tracer 18F-BMS-986192 By jnm.snmjournals.org Published On :: 2020-05-01T11:16:57-07:00 18F-BMS-986192, an adnectin-based human programmed cell death ligand 1 (PD-L1) tracer, was developed to non-invasively determine whole-body PD-L1 expression by positron emission tomography (PET). We evaluated usability of 18F-BMS-986192 PET to detect different PD-L1 expression levels and therapy-induced changes of PD-L1 expression in tumors. Methods: In vitro binding assays with 18F-BMS-986192 were performed in human tumor cell lines with different total cellular and membrane PD-L1 protein expression levels. Subsequently, PET imaging was executed in immunodeficient mice xenografted with these cell lines. Mice were treated with interferon gamma (IFN) intraperitoneally for 3 days or with the mitogen-activated protein kinase kinase (MEK1/2) inhibitor selumetinib by oral gavage for 24 hours. Thereafter 18F-BMS-986192 was administered intravenously, followed by a 60-minute dynamic PET scan. Tracer uptake was expressed as percentage injected dose per gram tissue (%ID/g). Tissues were collected to evaluate ex vivo tracer biodistribution and to perform flow cytometric, Western blot, and immunohistochemical tumor analyses. Results: 18F-BMS-986192 uptake reflected PD-L1 membrane levels in tumor cell lines, and tumor tracer uptake in mice was associated with PD-L1 expression measured immunohistochemically. In vitro IFN treatment increased PD-L1 expression in the tumor cell lines and caused up to 12-fold increase in tracer binding. In vivo, IFN did neither affect PD-L1 tumor expression measured immunohistochemically nor 18F-BMS-986192 tumor uptake. In vitro, selumetinib downregulated cellular and membrane levels of PD-L1 of tumor cells by 50% as measured by Western blotting and flow cytometry. In mice, selumetinib lowered cellular, but not membrane PD-L1 levels of tumors and consequently no treatment-induced change in 18F-BMS-986192 tumor uptake was observed. Conclusion: 18F-BMS-986192 PET imaging allows detection of membrane-expressed PD-L1, as soon as 60 minutes after tracer injection. The tracer can discriminate a range of tumor cell PD-L1 membrane expression levels. Full Article

ess Deletion of fatty acid transport protein 2 (FATP2) in the mouse liver changes the metabolic landscape by increasing the expression of PPAR{alpha}-regulated genes [Lipids] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 Fatty acid transport protein 2 (FATP2) is highly expressed in the liver, small intestine, and kidney, where it functions in both the transport of exogenous long-chain fatty acids and the activation of very-long-chain fatty acids. Here, using a murine model, we investigated the phenotypic impacts of deleting FATP2, followed by a transcriptomic analysis using unbiased RNA-Seq to identify concomitant changes in the liver transcriptome. WT and FATP2-null (Fatp2−/−) mice (5 weeks) were maintained on a standard chow diet for 6 weeks. The Fatp2−/− mice had reduced weight gain, lowered serum triglyceride, and increased serum cholesterol levels and attenuated dietary fatty acid absorption. Transcriptomic analysis of the liver revealed 258 differentially expressed genes in male Fatp2−/− mice and a total of 91 in female Fatp2−/− mice. These genes mapped to the following gene ontology categories: fatty acid degradation, peroxisome biogenesis, fatty acid synthesis, and retinol and arachidonic acid metabolism. Targeted RT-quantitative PCR verified the altered expression of selected genes. Of note, most of the genes with increased expression were known to be regulated by peroxisome proliferator–activated receptor α (PPARα), suggesting that FATP2 activity is linked to a PPARα-specific proximal ligand. Targeted metabolomic experiments in the Fatp2−/− liver revealed increases of total C16:0, C16:1, and C18:1 fatty acids; increases in lipoxin A4 and prostaglandin J2; and a decrease in 20-hydroxyeicosatetraenoic acid. We conclude that the expression of FATP2 in the liver broadly affects the metabolic landscape through PPARα, indicating that FATP2 provides an important role in liver lipid metabolism through its transport or activation activities.

ess Interaction Proteomics Identifies ERbeta Association with Chromatin Repressive Complexes to Inhibit Cholesterol Biosynthesis and Exert An Oncosuppressive Role in Triple-negative Breast Cancer [Research] By feedproxy.google.com Published On :: 2020-02-01T00:05:29-08:00 Triple-negative breast cancer (TNBC) is characterized by poor response to therapy and low overall patient survival. Recently, Estrogen Receptor beta (ERβ) has been found to be expressed in a fraction of TNBCs where, because of its oncosuppressive actions on the genome, it represents a potential therapeutic target, provided a better understanding of its actions in these tumors becomes available. To this end, the cell lines Hs 578T, MDA-MB-468 and HCC1806, representing the claudin-low, basal-like 1 and 2 TNBC molecular subtypes respectively, were engineered to express ERβ under the control of a Tetracycline-inducible promoter and used to investigate the effects of this transcription factor on gene activity. The antiproliferative effects of ERβ in these cells were confirmed by multiple functional approaches, including transcriptome profiling and global mapping of receptor binding sites in the genome, that revealed direct negative regulation by ERβ of genes, encoding for key components of cellular pathways associated to TNBC aggressiveness representing novel therapeutic targets such as angiogenesis, invasion, metastasis and cholesterol biosynthesis. Supporting these results, interaction proteomics by immunoprecipitation coupled to nano LC-MS/MS mass spectrometry revealed ERβ association with several potential nuclear protein partners, including key components of regulatory complexes known to control chromatin remodeling, transcriptional and post-transcriptional gene regulation and RNA splicing. Among these, ERβ association with the Polycomb Repressor Complexes 1 and 2 (PRC1/2), known for their central role in gene regulation in cancer cells, was confirmed in all three TNBC subtypes investigated, suggesting its occurrence independently from the cellular context. These results demonstrate a significant impact of ERβ in TNBC genome activity mediated by its cooperation with regulatory multiprotein chromatin remodeling complexes, providing novel ground to devise new strategies for the treatment of these diseases based on ligands affecting the activity of this nuclear receptor or some of its protein partners.

ess Repression of sphingosine kinase (SK)-interacting protein (SKIP) in acute myeloid leukemia diminishes SK activity and its re-expression restores SK function [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 Previous studies have shown that sphingosine kinase interacting protein (SKIP) inhibits sphingosine kinase (SK) function in fibroblasts. SK phosphorylates sphingosine producing the potent signaling molecule sphingosine-1-phosphate (S1P). SKIP gene (SPHKAP) expression is silenced by hypermethylation of its promoter in acute myeloid leukemia (AML). However, why SKIP activity is silenced in primary AML cells is unclear. Here, we investigated the consequences of SKIP down-regulation in AML primary cells and the effects of SKIP re-expression in leukemic cell lines. Using targeted ultra-HPLC-tandem MS (UPLC-MS/MS), we measured sphingolipids (including S1P and ceramides) in AML and control cells. Primary AML cells had significantly lower SK activity and intracellular S1P concentrations than control cells, and SKIP-transfected leukemia cell lines exhibited increased SK activity. These findings show that SKIP re-expression enhances SK activity in leukemia cells. Furthermore, other bioactive sphingolipids such as ceramide were also down-regulated in primary AML cells. Of note, SKIP re-expression in leukemia cells increased ceramide levels 2-fold, inactivated the key signaling protein extracellular signal-regulated kinase, and increased apoptosis following serum deprivation or chemotherapy. These results indicate that SKIP down-regulation in AML reduces SK activity and ceramide levels, an effect that ultimately inhibits apoptosis in leukemia cells. The findings of our study contrast with previous results indicating that SKIP inhibits SK function in fibroblasts and therefore challenge the notion that SKIP always inhibits SK activity.

ess The mitochondrial protein PGAM5 suppresses energy consumption in brown adipocytes by repressing expression of uncoupling protein 1 [Metabolism] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 Accumulating evidence suggests that brown adipose tissue (BAT) is a potential therapeutic target for managing obesity and related diseases. PGAM family member 5, mitochondrial serine/threonine protein phosphatase (PGAM5), is a protein phosphatase that resides in the mitochondria and regulates many biological processes, including cell death, mitophagy, and immune responses. Because BAT is a mitochondria-rich tissue, we have hypothesized that PGAM5 has a physiological function in BAT. We previously reported that PGAM5-knockout (KO) mice are resistant to severe metabolic stress. Importantly, lipid accumulation is suppressed in PGAM5-KO BAT, even under unstressed conditions, raising the possibility that PGAM5 deficiency stimulates lipid consumption. However, the mechanism underlying this observation is undetermined. Here, using an array of biochemical approaches, including quantitative RT-PCR, immunoblotting, and oxygen consumption assays, we show that PGAM5 negatively regulates energy expenditure in brown adipocytes. We found that PGAM5-KO brown adipocytes have an enhanced oxygen consumption rate and increased expression of uncoupling protein 1 (UCP1), a protein that increases energy consumption in the mitochondria. Mechanistically, we found that PGAM5 phosphatase activity and intramembrane cleavage are required for suppression of UCP1 activity. Furthermore, utilizing a genome-wide siRNA screen in HeLa cells to search for regulators of PGAM5 cleavage, we identified a set of candidate genes, including phosphatidylserine decarboxylase (PISD), which catalyzes the formation of phosphatidylethanolamine at the mitochondrial membrane. Taken together, these results indicate that PGAM5 suppresses mitochondrial energy expenditure by down-regulating UCP1 expression in brown adipocytes and that its phosphatase activity and intramembrane cleavage are required for UCP1 suppression.

The government is trying to convince the EU that it is serious about its red lines and is prepared to walk away from negotiations if the UK’s ‘regulatory freedom’ is not accepted – a no-deal scenario that would result in tariffs between the EU and the UK. Yet at the same time the story it is telling the world is that Britain is ‘re-emerging after decades of hibernation as a campaigner for global free trade’, as Boris Johnson put it in his speech in Greenwich a few weeks ago.The EU is understandably confused. It’s a bit odd to claim to be campaigning for free trade at the exact moment you are creating new barriers to trade. If Britain were so committed to frictionless trade, it wouldn’t have left the EU in the first place – and having decided to leave, it would have sought to maintain a close economic relationship with the EU, like that of Norway, rather than seek a basic trade deal like Canada’s. As well as creating confusion, the narrative also absurdly idealizes free trade. Johnson invoked Richard Cobden and the idea that free trade is ‘God’s diplomacy – the only certain way of uniting people in the bonds of peace since the more freely goods cross borders the less likely it is that troops will ever cross borders’. But the idea that free trade prevents war was shattered by the outbreak of the First World War, which brought to an end the first era of globalization.We also know that the domestic effects of free trade are more complex and problematic than Johnson suggested. Economic liberalization increases efficiency by removing friction but also creates disruption and has huge distributional consequences – that is, it creates winners and losers. In a democracy, these consequences need to be mitigated.In any case, the world today is not the same as the one in which Cobden lived. Tariffs are at a historically low level – and many non-tariff barriers have also been removed. In other words, most of the possible gains from trade liberalization have already been realized. Johnson talked about the dangers of a new wave of protectionism. But as the economist Dani Rodrik has argued, the big problem in the global economy is no longer a lack of openness, it is a lack of democratic legitimacy.The UK should therefore abandon this confusing and misleading narrative and own the way it is actually creating new barriers to trade – and do a better job of explaining the legitimate reasons for doing so. Instead of simplistically talking up free trade, we should be talking about the need to balance openness and economic efficiency with democracy and a sense of control, which is ultimately what Brexit was all about. Instead of claiming to be a ‘catalyst for free trade’, as Johnson put it, the UK should be talking about how it is trying to recalibrate globalization and, in doing so, make it sustainable.In the three decades after the end of the Cold War, globalization got out of control as barriers to the movement of capital and goods were progressively removed – what Rodrik called ‘hyper-globalization’ to distinguish it from the earlier, more moderate phase of globalization. This kind of deep integration necessitated the development of a system of rules, which have constrained the ability of states to pursue the kind of economic policy, particularly industrial policy, they want, and therefore undermined democracy.Hyper-globalization created a sense that ‘the nation state has fundamentally lost control of its destiny, surrendering to anonymous global forces’, as the economist Barry Eichengreen put it. Throughout the West, countries are all struggling with the same dilemma – how to reconcile openness and deep integration on the one hand, and democracy, sovereignty and a sense of control on the other.Within the EU, however, economic integration and the abolition of barriers to the movement of capital and goods went further than in the rest of the world – and the evolution of the principle of freedom of movement after the Maastricht Treaty meant that barriers to the internal movement of people were also eliminated as the EU was enlarged. What happened within the EU might be thought of as ‘hyper-regionalization’ – an extreme example, in a regional context, of a global trend.EU member states have lost control to an even greater extent than other nation states – albeit to anonymous regional rather than global forces – and this loss of control was felt intensely within the EU. It is therefore logical that this led to an increase in Euroscepticism. Whereas the left wants to restore some barriers to the movement of capital and goods, the right wants to restore barriers to the movement of people.However, having left the EU, the UK is uniquely well placed to find a new equilibrium. The UK has an ideological commitment to free trade that goes back to the movement to abolish the Corn Laws in the 1840s – which Johnson’s speech expressed. It is difficult to imagine the UK becoming protectionist in any meaningful sense. But at the same time, it has a well-developed sense of national and popular sovereignty, and the sense that the two go together – which is why it was so sensitive to the erosion of them through the EU. This means that Britain is unlikely to go to one extreme or the other.In other words, the UK may be the ideal country to find a new balance between openness and integration on the one hand, and a sense of control on the other. If it can find this balance – if it can make Brexit work – the UK could be a model for a wider recalibration of sustainable globalization. That, rather than fetishizing free trade, is the real contribution the UK can make.A version of this article was originally published in the Observer. Full Article
ess Emerging Lessons From COVID-19 By feedproxy.google.com Published On :: Thu, 02 Apr 2020 14:49:54 +0000 2 April 2020 Jim O'Neill Chair, Chatham House Exploring what lessons can be learned from the crisis to improve society and the functioning of our economic model going forward. 2020-04-02-COVID-Italy A man with a protective mask by the Coliseum in Rome during the height of Italy's COVID-19 epidemic. Photo by ALBERTO PIZZOLI/AFP via Getty Images. As tentative evidence emerges that Italy and Spain may have reached - or are close to - the peak of the curve, this could demonstrate that not only can Asian countries get to grips with COVID-19, but so can western democracies. And, if so, this offers a path for the rest of us.The last few weeks does demonstrate there is a role for governments to intervene in society, whether it be health, finance or any walk of life, as they have had to implement social distancing. Some have been forced, and the interventions are almost definitely only temporary, but perhaps some others may be less so.Governments of all kinds now realise there is a connection between our health system quality and our economic capability. On an index of global economic sustainability that I presided over creating when I was at Goldman Sachs, the top ten best performing countries on growth environment scores includes eight of the best performing ten countries - so far- in handling the crisis in terms of deaths relative to their population.Health system qualityThe top three on the index (last calculated in 2014) were Singapore, Hong Kong and South Korea, all of which are exemplary to the rest of us on how to deal with this mess. This suggests that once we are through this crisis, a number of larger populated countries - and their international advisors such as the IMF - might treat the quality of countries' health systems just as importantly as many of the other more standard indicators in assessing ability to deal with shocks.Policymakers have also been given a rather stark warning about other looming health disasters, especially antimicrobial resistance, of which antibiotic resistance lies at the heart. An independent review I chaired recommended 29 interventions, requiring $42 bn worth of investment, essentially peanuts compared to the costs of no solution, and the current economic collapse from COVID-19. It would seem highly likely to me that policymakers are going to treat this more seriously now.As a clear consequence of the - hopefully, temporary - global economic collapse, our environment suddenly seems to be cleaner and fresher and, in this regard, we have bought some time in the battle against climate change. Surely governments are going to be able to have a bigger influence on fossil fuel extractors and intense users as we emerge from this crisis?For any industries requiring government support, the government can make it clear this is dependent on certain criteria. And surely the days of excessive use of share buy backs and extreme maximisation of profit at the expense of other goals, are over?It seems to me an era of 'optimisation' of a number of business goals is likely to be the mantra, including profits but other things too such as national equality especially as it relates to income. Here in the UK, the government has offered its strongest fiscal support to the lower end of the income earning range group and, in a single swoop, has presided over its most dramatic step towards narrowing income inequality for a long time.This comes on top of a period of strong initiatives to support higher levels of minimum earnings, meaning we will emerge later in 2020, into 2021, and beyond, with lower levels of income inequality.The geographic issue of rural versus urban is also key. COVID-19 has spread more easily in more tightly packed cities such as London, New York and many others. More geographically remote places, by definition, are better protected. Perhaps now there will be some more thought given by policymakers to the quality and purpose of life outside our big metropolitan areas.Lastly, will China emerge from this crisis by offering a mammoth genuine gesture to the rest of the world, and come up, with, unlike, in 2008, a fiscal stimulus to its own consumers, that is geared towards importing a lot of things from the rest of the world? Now that would be good way of bringing the world back together again.This is a version of an article originally published in The Article Full Article

ess The lncRNA Gm15622 stimulates SREBP-1c expression and hepatic lipid accumulation by sponging the miR-742-3p in mice [Research Articles] By feedproxy.google.com Published On :: 2020-03-30T14:36:26-07:00 Excessive lipid deposition is a hallmark of nonalcoholic fatty liver disease (NAFLD). Although much has been learned about the enzymes and metabolites involved in NAFLD, few studies have focused on the role of long non-coding RNAs (lncRNAs) in hepatic lipid accumulation. Here, using in vitro and in vivo models of NAFLD, we found that the lncRNA Gm15622 is highly expressed in the liver of obese mice fed a high-fat diet (HFD) and in murine liver (AML-12) cells treated with free fatty acids. Investigating the molecular mechanism in the liver-enriched expression of Gm15622 and its effects on lipid accumulation in hepatocytes and on NAFLD pathogenesis, we found that Gm15622 acts as a sponge for the microRNA miR-742-3p. This sponging activity increased the expression of the transcriptional regulator sterol regulatory element–binding transcription factor 1c (SREBP-1c) and promoted lipid accumulation in the liver of the HFD mice and AML-12 cells. Moreover, further results indicated that metformin suppresses Gm15622 and alleviates NAFLD-associated lipid deposition in mice. In conclusion, we have identified an lncRNA Gm15622–miR-742-3p–SREBP-1c regulatory circuit associated with NAFLD in mice, a finding that significantly advances our insight into how lipid metabolism and accumulation are altered in this metabolic disorder. Our results also suggest that Gm15622 may be a potential therapeutic target for managing NAFLD. Full Article

ess COVID 19: Assessing Vulnerabilities and Impacts on Iraq By feedproxy.google.com Published On :: Tue, 07 Apr 2020 14:33:01 +0000 7 April 2020 Dr Renad Mansour Senior Research Fellow, Middle East and North Africa Programme; Project Director, Iraq Initiative @renadmansour Dr Mac Skelton Director, Institute of Regional and International Studies (IRIS), American University of Iraq, Sulaimani; Visiting Fellow, Middle East Centre, London School of Economics Dr Abdulameer Mohsin Hussein President of the Iraq Medical Association Following 17 years of conflict and fragile state-society relations, the war-torn country is particularly vulnerable to the pandemic. 2020-04-07-Iraq-COVID-spray Disinfecting shops in Baghdad's Bayaa neighbourhood as a preventive measure against the spread of COVID-19. Photo by AHMAD AL-RUBAYE/AFP via Getty Images. Iraq is a country already in turmoil, suffering fallout from the major military escalation between the US and Iran, mass protests calling for an end to the post-2003 political system, and a violent government crackdown killing more than 600 and wounding almost 30,000 - all presided over by a fragmented political elite unable to agree upon a new prime minister following Adil abd al-Mehdi’s resignation back in November.COVID-19 introduces yet another threat to the fragile political order, as the virus exposes Iraq’s ineffective public health system dismantled through decades of conflict, corruption and poor governance.Iraqi doctors are making every effort to prepare for the worst-case scenario, but they do so with huge structural challenges. The Ministry of Health lacks enough ICU beds, human resources, ventilators, and personal protective equipment (PPE). Bogged down in bureaucracy, the ministry is struggling to process procurements of equipment and medications, and some doctors have made purchases themselves.But individual efforts can only go so far as many Iraqi doctors are concerned the official numbers of confirmed COVID-19 cases do not reflect the complexity of the situation on the ground.The ministry relies predominately upon patients self-presenting at designated public hospitals and has only just begun community-based testing in areas of suspected clusters. Reliance on self-presentation requires a level of trust between citizens and state institutions, which is at a historic low. This gap in trust – 17 years in the making – puts Iraq’s COVID-19 response particularly at risk.Iraq’s myriad vulnerabilitiesCertain social and political factors leave Iraq uniquely exposed to the coronavirus. The country’s vulnerability is tied directly to its social, religious and economic interconnections with Iran, an epicenter of the pandemic.Exchanges between Iran and Iraq are concentrated in two regions, with strong cross-border links between Iraqi and Iranian Kurds in the north-east, and Iraqi and Iranian Shia pilgrims in the south. Cross-border circulation of religious pilgrims is particularly concerning, as they can result in mass ritual gatherings.The high number of confirmed cases in the southern and northern peripheries of the country puts a spotlight on Iraq's failure in managing healthcare. The post-2003 government has failed to either rebuild a robust centralized healthcare system, or to pave the way for a federalized model.Caught in an ambiguous middle between a centralized and federalized model, coordination across provinces and hospitals during the coronavirus crisis has neither reflected strong management from Baghdad nor robust ownership at the governorate level.This problem is part of a wider challenge of managing centre-periphery relations and federalism, which since 2003 has not worked effectively. Baghdad has provided all 18 provinces with instructions on testing and treatment, but only a handful have enough resources to put them into practice. Advanced testing capacity is limited to the five provinces with WHO-approved centers, with the remaining 13 sending swabs to Baghdad.But the greatest challenge to Iraq’s COVID-19 response is the dramatic deterioration of state-society relations. Studies reveal a profound societal distrust of Iraq’s public healthcare institutions, due to corruption and militarization of medical institutions. Numerous videos have recently circulated of families refusing to turn over sick members - particularly women - to medical teams visiting households with confirmed or suspected cases.As medical anthropologist Omar Dewachi notes, the ‘moral economy of quarantine’ in Iraq is heavily shaped by a history of war and its impact on the relationship between people and the state. Although local and international media often interpret this reluctance to undergo quarantine as a matter of social or tribal norms, distrusting the state leads many families to refuse quarantine because they believe it resembles a form of arrest.The management of coronavirus relies upon an overt convergence between medical institutions and security forces as the federal police collaborate with the Ministry of Health to impose curfews and enforce quarantine. This means that, troublingly, the same security establishment which violently cracked down on protesters and civil society activists is now the teeth behind Iraq’s COVID-19 response.Without trust between society and the political class, civil society organizations and protest movements have directed their organizational structure towards awareness-raising across Iraq. Key religious authorities such as Grand Ayatollah Sistani have called for compliance to the curfew and mobilized charitable institutions.However, such efforts will not be enough to make up for the lack of governance at the level of the state. In the short-term, Iraq’s medical professionals and institutions are in dire need of technical and financial support. In the long-term, COVID-19 is a lesson that Iraq’s once robust public healthcare system needs serious investment and reform.COVID-19 may prove to be another catalyst challenging the ‘muddle through’ logic of the Iraqi political elite. International actors have largely been complicit in this logic, directing aid and technical support towards security forces and political allies in the interest of short-term stability, and neglecting institutions which Iraqis rely on for health, education, and well-being.The response to the crisis requires cooperation and buy-in of a population neglected by 17 years of failed governance. This is a seminal event that may push the country to the brink, exposing and stirring underlying tensions in state-society relations.This analysis was produced as part of the Iraq Initiative.

ess Justice for the Rohingya: Lessons from the Khmer Rouge Tribunal By feedproxy.google.com Published On :: Wed, 08 Apr 2020 12:22:46 +0000 8 April 2020 Sandra Smits Programme Manager, Asia-Pacific Programme The Cambodian case study illustrates the challenges of ensuring justice and accountability for the Rohingya in Myanmar. 2020-04-08-Rohingya.jpg Coast guards escort Rohingya refugees following a boat capsizing accident in Teknaf on 11 February 2020. Photo: Getty Images. International criminal justice provides a stark reminder that state sovereignty is not an absolute, and that the world’s most heinous crimes should be prosecuted at an international level, particularly where domestic systems lack the capacity or will to hold perpetrators to account. The post-Cold War period witnessed a dramatic rise in the number of international tribunals with jurisdiction over war crimes and serious human rights abuses in countries including Cambodia, East Timor, Rwanda, Liberia, Sierra Leone and Yugoslavia. With these processes approaching, or having reached the end of their dockets, many have called for the creation of new tribunals to address more recent conflicts, including the army crackdown in Myanmar in 2017 that resulted in evidence of crimes against humanity against the Rohingya. In January this year, the International Court of Justice (ICJ) imposed emergency provisional measures on Myanmar, instructing it to prevent genocidal violence against its Rohingya minority. But a final judgement is expected to take years and the ICJ has no way of enforcing these interim measures. Myanmar has already responded defiantly to international criticism. Model for justiceMyanmar is not the first country to face scrutiny for such crimes in Southeast Asia. The Extraordinary Chambers in the Courts of Cambodia (ECCC), more commonly known as the Khmer Rouge Tribunal was established in 1997 to prosecute Khmer Rouge leaders for alleged violations of international law and serious crimes perpetrated during the Cambodian genocide. This provides an opportunity to consider whether the Tribunal can act as a ‘hybrid’ model for justice in the region. The first lesson that can be taken from the Cambodian context is that the state must have the political will and commitment to pursue accountability. It was indeed the Cambodian government itself, who requested international assistance from the United Nations (UN), to organize a process for holding trials. The initial recommendation of the UN-commissioned Group of Experts was for the trial to be held under UN control, in light of misgivings about Cambodia’s judicial system. Prime Minister Hun Sen rejected this assessment and in prolonged negotiations, continued to spearhead the need for domestic involvement (arguably, in order to circumscribe the search for justice). This eventually resulted in the creation of a hybrid body consisting of parallel international and Cambodian judges and prosecutors with supermajority decision-making rules. It is worth noting that the Hun Sen government initially chose to do business with former Khmer Rouge leaders, until it became more advantageous to embrace a policy of putting them on trial. It is possible to infer from this that there will be no impetus for action in Myanmar until it is domestically advantageous to do so. At present, this appetite is clearly lacking, demonstrated by de-facto leader Aung San Suu Kyi shying away from accountability and instead defending the government’s actions before the ICJ.One unique aspect of the Khmer Rouge Tribunal has been the vast participation by the Cambodian people in witnessing the trials as well as widespread support for the tribunal. This speaks to the pent-up demand in Cambodia for accountability and the importance of local participation. While international moral pressure is clear, external actors cannot simply impose justice for the Rohingya when there is no domestic incentive or support to pursue this. The reality is that the anti-Rohingya campaign has galvanized popular support from the country’s Buddhist majority. What is more, the Rohingya are not even seen as part of Myanmar so there is an additional level of disenfranchisement.Secondly, the Cambodian Tribunal illustrates the need for safeguards against local political interference. The ECCC was designed as national court with international participation. There was an agreement to act in accordance with international standards of independence and impartiality, but no safeguards in place against serious deficiencies in the Cambodian judicial system. Close alliances between judges and the ruling Cambodian People’s Party, as well as high levels of corruption meant the tribunal effectively gave Hun Sen’s government veto power over the court at key junctures. Despite the guise of a hybrid structure, the Cambodian government ultimately retained the ability to block further prosecutions and prevent witnesses from being called. In Myanmar, political interference could be a concern, but given there is no popular support for justice and accountability for crimes committed against the Rohingya, the prospects of a domestic or hybrid process remain unlikely. However, there are still international options. The investigation by the International Criminal Court (ICC) into crimes that may have taken place on the Myanmar–Bangladesh border represents a potential route for justice and accountability. The UN Human Rights Council has also recently established the Independent Investigative Mechanism for Myanmar (IIMM), mandated to collect and preserve evidence, as well as to prepare files for future cases before criminal courts.Finally, the Cambodian case illustrates the culture of impunity in the region. The ECCC was conceived partly as a showcase for international standards of justice, which would have a ‘contagion effect’ upon the wider Cambodian and regional justice systems. Cambodia was notorious for incidents in which well-connected and powerful people flouted the law. This culture of impunity was rooted in the failure of the government to arrest, try and punish the Khmer Rouge leadership. The Tribunal, in holding perpetrators of the worst crimes to account, sought to send a clear signal that lesser violations would not be tolerated in the same way. Arguably, it did not achieve this in practice as Cambodia still has a highly politicized judicial system with high levels of corruption and clear limits to judicial independence. What this illustrates is that the first step towards accountability is strengthening domestic institutions. The United Nation’s Special Rapporteur on the situation of human rights in Myanmar has urged domestic authorities to embrace democracy and human rights, highlighting the need to reform the judicial system in order to ensure judicial independence, remove systemic barriers to accountability and build judicial and investigatory capacity in accordance with international standards. Based on this assessment, it is clear that domestic institutions are currently insufficiently independent to pursue accountability.The ECCC, despite its shortcomings, does stand as proof that crimes against humanity will not go completely unpunished. However, a process does not necessarily equal justice. The region is littered with justice processes that never went anywhere: Indonesia, Nepal, and Sri Lanka. International recourse is also challenging in a region with low ratification of the ICC, and the absence of regional mechanisms like the Inter-American Court of Human Rights, the European Court of Human Rights, and the African Court on Human and Peoples’ Rights (although their remit is not mass atrocity prosecutions). The Cambodian case study illustrates the challenges of ensuring justice and accountability within the region. The end of impunity is critical to ensure peaceful societies, but a purely legalistic approach will fail unless it is supported by wider measures and safeguards. It is these challenges, that undermine the prospects for ensuring justice for the Rohingya within Myanmar. Full Article
ess Legal Provision for Crisis Preparedness: Foresight not Hindsight By feedproxy.google.com Published On :: Tue, 21 Apr 2020 17:03:31 +0000 21 April 2020 Dr Patricia Lewis Research Director, Conflict, Science & Transformation; Director, International Security Programme @PatriciaMary COVID-19 is proving to be a grave threat to humanity. But this is not a one-off, there will be future crises, and we can be better prepared to mitigate them. 2020-04-21-Nurse-COVID-Test Examining a patient while testing for COVID-19 at the Velocity Urgent Care in Woodbridge, Virginia. Photo by Chip Somodevilla/Getty Images. A controversial debate during COVID-19 is the state of readiness within governments and health systems for a pandemic, with lines of the debate drawn on the issues of testing provision, personal protective equipment (PPE), and the speed of decision-making.President Macron in a speech to the nation admitted French medical workers did not have enough PPE and that mistakes had been made: ‘Were we prepared for this crisis? We have to say that no, we weren’t, but we have to admit our errors … and we will learn from this’.In reality few governments were fully prepared. In years to come, all will ask: ‘how could we have been better prepared, what did we do wrong, and what can we learn?’. But after every crisis, governments ask these same questions.Most countries have put in place national risk assessments and established processes and systems to monitor and stress-test crisis-preparedness. So why have some countries been seemingly better prepared?Comparing different approachesSome have had more time and been able to watch the spread of the disease and learn from those countries that had it first. Others have taken their own routes, and there will be much to learn from comparing these different approaches in the longer run.Governments in Asia have been strongly influenced by the experience of the SARS epidemic in 2002-3 and - South Korea in particular - the MERS-CoV outbreak in 2015 which was the largest outside the Middle East. Several carried out preparatory work in terms of risk assessment, preparedness measures and resilience planning for a wide range of threats.Case Study of Preparedness: South KoreaBy 2007, South Korea had established the Division of Public Health Crisis Response in Korea Centers for Disease Control and Prevention (KCDC) and, in 2016, the KCDC Center for Public Health Emergency Preparedness and Response had established a round-the-clock Emergency Operations Center with rapid response teams.KCDC is responsible for the distribution of antiviral stockpiles to 16 cities and provinces that are required by law to hold and manage antiviral stockpiles.And, at the international level, there are frameworks for preparedness for pandemics. The International Health Regulations (IHR) - adopted at the 2005 World Health Assembly and binding on member states - require countries to report certain disease outbreaks and public health events to the World Health Organization (WHO) and ‘prevent, protect against, control and provide a public health response to the international spread of disease in ways that are commensurate with and restricted to public health risks, and which avoid unnecessary interference with international traffic and trade’.Under IHR, governments committed to a programme of building core capacities including coordination, surveillance, response and preparedness. The UN Sendai Framework for Disaster Risk highlights disaster preparedness for effective response as one of its main purposes and has already incorporated these measures into the Sustainable Development Goals (SDGs) and other Agenda 2030 initiatives. UN Secretary-General António Guterres has said COVID-19 ‘poses a significant threat to the maintenance of international peace and security’ and that ‘a signal of unity and resolve from the Council would count for a lot at this anxious time’.Case Study of Preparedness: United StatesThe National Institutes of Health (NIH) and the Center for Disease Control (CDC) established PERRC – the Preparedness for Emergency Response Research Centers - as a requirement of the 2006 Pandemic and All-Hazards Preparedness Act, which required research to ‘improve federal, state, local, and tribal public health preparedness and response systems’.The 2006 Act has since been supplanted by the 2019 Pandemic and All-Hazards Preparedness and Advancing Innovation Act. This created the post of Assistant Secretary for Preparedness and Response (ASPR) in the Department for Health and Human Services (HHS) and authorised the development and acquisitions of medical countermeasures and a quadrennial National Health Security Strategy.The 2019 Act also set in place a number of measures including the requirement for the US government to re-evaluate several important metrics of the Public Health Emergency Preparedness cooperative agreement and the Hospital Preparedness Program, and a requirement for a report on the states of preparedness and response in US healthcare facilities.This pandemic looks set to continue to be a grave threat to humanity. But there will also be future pandemics – whether another type of coronavirus or a new influenza virus – and our species will be threatened again, we just don’t know when.Other disasters too will befall us – we already see the impacts of climate change arriving on our doorsteps characterised by increased numbers and intensity of floods, hurricanes, fires, crop failure and other manifestations of a warming, increasingly turbulent atmosphere and we will continue to suffer major volcanic eruptions, earthquakes and tsunamis. All high impact, unknown probability events.Preparedness for an unknown future is expensive and requires a great deal of effort for events that may not happen within the preparers’ lifetimes. It is hard to imagine now, but people will forget this crisis, and revert to their imagined projections of the future where crises don’t occur, and progress follows progress. But history shows us otherwise.Preparations for future crises always fall prey to financial cuts and austerity measures in lean times unless there is a mechanism to prevent that. Cost-benefit analyses will understandably tend to prioritise the urgent over the long-term. So governments should put in place legislation – or strengthen existing legislation – now to ensure their countries are as prepared as possible for whatever crisis is coming.Such a legal requirement would require governments to report back to parliament every year on the state of their national preparations detailing such measures as:The exact levels of stocks of essential materials (including medical equipment)The ability of hospitals to cope with large influx of patientsHow many drills, exercises and simulations had been organised – and their findingsWhat was being done to implement lessons learned & improve preparednessIn addition, further actions should be taken:Parliamentary committees such as the UK Joint Committee on the National Security Strategy should scrutinise the government’s readiness for the potential threats outlined in the National Risk register for Civil Emergencies in-depth on an annual basis.Parliamentarians, including ministers, with responsibility for national security and resilience should participate in drills, table-top exercises and simulations to see for themselves the problems inherent with dealing with crises.All governments should have a minister (or equivalent) with the sole responsibility for national crisis preparedness and resilience. The Minister would be empowered to liaise internationally and coordinate local responses such as local resilience groups.There should be ring-fenced budget lines in annual budgets specifically for preparedness and resilience measures, annually reported on and assessed by parliaments as part of the due diligence process.And at the international level:The UN Security Council should establish a Crisis Preparedness Committee to bolster the ability of United Nations Member States to respond to international crisis such as pandemics, within their borders and across regions. The Committee would function in a similar fashion as the Counter Terrorism Committee that was established following the 9/11 terrorist attacks in the United States.States should present reports on their level of preparedness to the UN Security Council. The Crisis Preparedness Committee could establish a group of experts who would conduct expert assessments of each member state’s risks and preparedness and facilitate technical assistance as required.Regional bodies such as the OSCE, ASEAN and ARF, the AU, the OAS, the PIF etc could also request national reports on crisis preparedness for discussion and cooperation at the regional level.COVID-19 has been referred to as the 9/11 of crisis preparedness and response. Just as that shocking terrorist attack shifted the world and created a series of measures to address terrorism, we now recognise our security frameworks need far more emphasis on being prepared and being resilient. Whatever has been done in the past, it is clear that was nowhere near enough and that has to change.Case Study of Preparedness: The UKThe National Risk Register was first published in 2008 as part of the undertakings laid out in the National Security Strategy (the UK also published the Biological Security Strategy in July 2018). Now entitled the National Risk Register for Civil Emergencies it has been updated regularly to analyse the risks of major emergencies that could affect the UK in the next five years and provide resilience advice and guidance.The latest edition - produced in 2017 when the UK had a Minister for Government Resilience and Efficiency - placed the risk of a pandemic influenza in the ‘highly likely and most severe’ category. It stood out from all the other identified risks, whereas an emerging disease (such as COVID-19) was identified as ‘highly likely but with moderate impact’.However, much preparatory work for an influenza pandemic is the same as for COVID-19, particularly in prepositioning large stocks of PPE, readiness within large hospitals, and the creation of new hospitals and facilities.One key issue is that the 2017 NHS Operating Framework for Managing the Response to Pandemic Influenza was dependent on pre-positioned ’just in case’ stockpiles of PPE. But as it became clear the PPE stocks were not adequate for the pandemic, it was reported that recommendations about the stockpile by NERVTAG (the New and Emerging Respiratory Virus Threats Advisory Group which advises the government on the threat posed by new and emerging respiratory viruses) had been subjected to an ‘economic assessment’ and decisions reversed on, for example, eye protection.The UK chief medical officer Dame Sally Davies, when speaking at the World Health Organization about Operation Cygnus – a 2016 three-day exercise on a flu pandemic in the UK – reportedly said the UK was not ready for a severe flu attack and ‘a lot of things need improving’.Aware of the significance of the situation, the UK Parliamentary Joint Committee on the National Security Strategy launched an inquiry in 2019 on ‘Biosecurity and human health: preparing for emerging infectious diseases and bioweapons’ which intended to coordinate a cross-government approach to biosecurity threats. But the inquiry had to postpone its oral hearings scheduled for late October 2019 and, because of the general election in December 2019, the committee was obliged to close the inquiry. Full Article
ess COVID-19 Crisis – Business as Usual for Gaza? By feedproxy.google.com Published On :: Wed, 06 May 2020 14:48:14 +0000 6 May 2020 Mohammed Abdalfatah Asfari Foundation Academy Fellow @mhalabi258 LinkedIn The COVID-19 pandemic has brought unprecedented challenges, economic collapse and strict lockdowns in many parts of the world. For the people of Gaza, this reality is nothing new. 2020-05-06-covid-19-gaza.jpg Palestinians light fireworks above the rubble during the Muslim holy month of Ramadan amid concerns about the spread of the coronavirus disease (COVID-19), in Gaza City , 30 April 2020. Photo by Majdi Fathi/NurPhoto via Getty Images. In August 2012, when the UN released its report Gaza in 2020: A liveable place?, they could not have imagined what the world would look like in 2020: cities under lockdown, restrictions on movement, border closures, widespread unemployment, economic collapse, fear and anxiety and, above all, uncertainty about what the future holds.For Gaza’s population of 2 million people this reality is nothing new. The conditions that the rest of the world are currently experiencing as a result of the COVID-19 pandemic is similar to the tight blockade Gaza has been living under ever since Hamas took over in 2007. Israel has imposed severe restrictions on the movement of people and goods, youth unemployment has reached 60 per cent, and over 80 per cent of Gaza’s population are now dependent on international aid.The people of Gaza are having to face the COVID-19 crisis already at a disadvantage, with poor infrastructure, limited resources and a shortage of the most basic services, such as water and power supply. It also has a fragile health system, with hospitals lacking essential medical supplies and equipment, as well as the capacity to deal with the outbreak as there are only 84 ICU beds and ventilators available. Meanwhile, intra-Palestinian divisions have persisted and were evident in the initial reaction to the pandemic. When President Mahmoud Abbas announced a state of emergency, it took two days for the Hamas-led government in Gaza to follow suit and shut down schools and universities. They later made a separate emergency appeal to address the crisis and prepare for a COVID-19 response in Gaza. This lack of coordination is typical of the way the Palestinian Authority and Hamas approach crisis situations.After the initial uncoordinated response, Hamas, as the de-facto ruler of Gaza, has asserted its ability to control Gaza’s borders by putting in place quarantine measures for everyone who enters the strip, whether through the Erez checkpoint with Israel or the Rafah border with Egypt. They have also assigned 21 hospitals, hotels, and schools as compulsory quarantine centres for all arrivals from abroad, who have to stay in quarantine for 21 days. In comparison, there are 20 quarantine centres in the West Bank. These strict measures have prevented the spread of the virus in the community and confined it to the quarantine centres, with only 20 confirmed cases of COVID-19 as of 6 May. Gaza’s de-facto authorities have also been able to monitor markets and prices to ensure the availability of essential goods.Faced with a major crisis, Al-Qassam Brigades – the armed wing of Hamas – have tried to play the role of a national army by participating in efforts to fight the pandemic. They have relatively good logistical capacity and have contributed to the construction of two quarantine facilities with a total capacity of 1,000 units to prepare for more arrivals into Gaza. At the local level, municipalities have been disinfecting public spaces and facilities in addition to disseminating information about the virus and related preventative and protective measures. Other precautionary measures put in place include closing the weekly open markets, and restricting social gatherings like weddings and funerals.Despite COVID-19, it’s business as usual when it comes to international dealings with Gaza. The key parties in the conflict – Israel, Hamas and the Palestinian Authority – along with the main external actors – Egypt, the United Nations and Qatar – have continued to stick to their policies aimed at keeping the security situation under control and preventing further escalation. Although Israel has allowed entry of pharmaceutical supplies and medical equipment into Gaza during the pandemic, it has kept its restrictions on the movement of goods and people in place, while keeping a close eye on the development of the COVID-19 outbreak in Gaza – a major outbreak here would be a nightmare scenario for Israel.Meanwhile, Qatar has continued to address the humanitarian and economic needs of Gaza in an attempt to ease the pressure and prevent further escalation. It has pledged $150 million over the next six months to help families in Gaza from poorer backgrounds. Gaza has also been discussed by the Middle East Quartet, as Nickolay Mladenov, the UN special coordinator for the Middle East Peace Process, expressed his concern about the risk of a disease outbreak in Gaza during a call with the members of the Quartet.Amid the pandemic, threats are still being exchanged between Israel and Hamas. The Israeli defence minister, Naftali Bennett, requested that in return for providing humanitarian aid to Gaza, Hamas agrees to return the remains of two Israeli soldiers killed in the 2014 war. While openly rejecting Bennett's statement, the leader of Hamas in Gaza, Yahya Sinwar, has offered to move forward with a prisoner swap deal if Israel agrees to release elderly prisoners and detainees in addition to detained women and children. Though dealing with its own COVID-19 outbreak, Egypt has started to mediate between the two parties in an attempt to stabilize the situation and reach a prisoner swap deal.In the wake of this pandemic, lessons should be learned and policies should be examined, by all parties. Firstly, Israel should re-evaluate its security measures towards Gaza by easing restrictions on movement and trade which would have a positive impact on living conditions for Gaza’s population. The current measures have proven to be unsustainable and have contributed to the endless cycle of violence. Secondly, the intra-Palestinian division should end, to save Palestinians from contradictory policies and insufficient capacity on both sides. In fact, all previous attempts have failed to end this self-destructive division and this is due to the absence of political will on both sides. Elections seem to be the only viable path towards unity. Finally, efforts by the international community should go beyond stabilizing the security situation and ongoing crisis inside Gaza, where disruption of normal life is the norm.While the world has reacted to this pandemic with a whole host of new policies and emergency measures, it has remained business as usual when dealing with Gaza. Should COVID-19 spread in Gaza, its people – who have already paid the price of a continuous blockade and intra-Palestinian division for 13 years – will pay a heavy price yet again. However, this time it is not a crisis that they alone will have to face. Full Article
ess Oxidative stress-mediated regulation of proteasome complexes [Other] By feedproxy.google.com Published On :: 2011-01-31T16:50:35-08:00 Oxidative stress has been implicated in aging and many human diseases, notably neurodegenerative disorders and various cancers. The reactive oxygen species that are generated by aerobic metabolism and environmental stressors can chemically modify proteins and alter their biological functions. Cells possess protein repair pathways to rescue oxidized proteins and restore their functions. If these repair processes fail, oxidized proteins may become cytotoxic. Cell homeostasis and viability are therefore dependent on the removal of oxidatively damaged proteins. Numerous studies have demonstrated that the proteasome plays a pivotal role in the selective recognition and degradation of oxidized proteins. Despite extensive research, oxidative stress-triggered regulation of proteasome complexes remains poorly defined. Better understanding of molecular mechanisms underlying proteasome function in response to oxidative stress will provide a basis for developing new strategies aimed at improving cell viability and recovery as well as attenuating oxidation-induced cytotoxicity associated with aging and disease. Here we highlight recent advances in the understanding of proteasome structure and function during oxidative stress and describe how cells cope with oxidative stress through proteasome-dependent degradation pathways.
