stem The Destabilizing Danger of Cyberattacks on Missile Systems By feedproxy.google.com Published On :: Tue, 02 Jul 2019 08:40:06 +0000 2 July 2019 Dr Patricia Lewis Research Director, Conflict, Science & Transformation; Director, International Security Programme @PatriciaMary Dr Beyza Unal Senior Research Fellow, International Security Programme @beyzaunal Google Scholar ‘Left-of-launch’ attacks that aim to disable enemy missile systems may increase the chance of them being used, not least because the systems are so vulnerable. 2019-07-02-NKMissile.jpg This undated photo released by North Korea's news agency in March 2017 shows the launch of four ballistic missiles during a military drill at an undisclosed location in North Korea. Photo: STR/AFP/Getty Images. After President Trump decided to halt a missile attack on Iran in response to the downing of a US drone, it was revealed that the US had conducted cyberattacks on Iranian weapons systems to prevent Iran launching missiles against US assets in the region.This ‘left-of-launch’ strategy – the pre-emptive action to prevent an adversary launch missiles – has been part of the US missile defence strategy for some time now. President George W Bush asked the US military and intelligence community to infiltrate the supply chain of North Korean missiles. It was claimed that the US hacked the North Korean ballistic missile programme, causing a failed ballistic missile test, in 2012.It was not clear then – or now – whether these ‘left-of-launch’ cyberattacks aimed at North Korea were successful as described or whether they were primarily a bluff. But that is somewhat irrelevant; the belief in the possibility and the understanding of the potential impact of such cyber capabilities undermines North Korean or Iranian confidence in their abilities to launch their missiles. In times of conflict, loss of confidence in weapons systems may lead to escalation.In other words, the adversary may be left with no option but to take the chance to use these missiles or to lose them in a conflict setting. ‘Left of launch’ is a dangerous game. If it is based on a bluff, it could be called upon and lead to deterrence failure. If it is based on real action, then it could create an asymmetrical power struggle. If the attacker establishes false confidence in the power of a cyber weapon, then it might lead to false signalling and messaging.This is the new normal. The cat-and-mouse game has to be taken seriously, not least because missile systems are so vulnerable.There are several ways an offensive cyber operation against missile systems might work. These include exploiting missile designs, altering software or hardware, or creating clandestine pathways to the missile command and control systems.They can also be attacked in space, targeting space assets and their link to strategic systems.Most missile systems rely, at least in part, on digital information that comes from or via space-based or space-dependent assets such as: communication satellites; satellites that provide position, navigation and timing (PNT) information (for example GPS or Galileo); weather satellites to help predict flight paths, accurate targeting and launch conditions; and remote imagery satellites to assist with information and intelligence for the planning and targeting.Missile launches themselves depend on 1) the command and control systems of the missiles, 2) the way in which information is transmitted to the missile launch facilities and 3) the way in which information is transmitted to the missiles themselves in flight. All these aspects rely on space technology.In addition, the ground stations that transmit and receive data to and from satellites are also vulnerable to cyberattack – either through their known and unknown internet connectivity or through malicious use of flash drives that contain a deliberate cyber infection.Non-space-based communications systems that use cable and ground-to-air-to-ground masts are likewise under threat from cyberattacks that find their way in via internet connectivity, proximity interference or memory sticks. Human error in introducing connectivity via phones, laptops and external drives, and in clicking on malicious links in sophisticated phishing lures, is common in facilitating inadvertent connectivity and malware infection.All of these can create a military capacity able to interfere with missile launches. Malware might have been sitting on the missile command and control system for months or even years, remaining inactivated until a chosen time or by a trigger that sets in motion a disruption either to the launch or to the flight path of the missile. The country that launches the missile that either fails to launch or fails to reach the target may never know if this was the result of a design flaw, a common malfunction or a deliberate cyberattack.States with these capabilities must exercise caution: cyber offence manoeuvres may prevent the launch of missile attacks against US assets in the Middle East or in the Pacific regions, but they may also interfere with US missile launches in the future. Even, as has recently been revealed, US cyber weapons targeting an adversary may blow back and inadvertently infect US systems. Nobody is invulnerable. Full Article
stem Webinar: Reimagining the Role of State and Non-State Actors in (Re)building National Health Systems in the Arab World By feedproxy.google.com Published On :: Wed, 15 Apr 2020 14:15:01 +0000 Research Event 22 April 2020 - 1:00pm to 2:00pm Event participants Fadi El-Jardali, Professor of Health Policy and Systems, American University of BeirutModerator: Nadim Houry, Executive Director, Arab Reform Initiative As new cases of COVID-19 continue to surge, countries around the world struggle to mitigate the public health and economic effects of the virus. It is becoming increasingly clear that an effective pandemic response requires a whole-of-government, whole-of-society approach. In the Arab world, where health systems are already strained by armed conflicts and displaced populations, a whole-of-society response to the pandemic is particularly critical as countries have become increasingly dependent on non-state actors, notably the private sector, for healthcare provision and any response that includes the state alone may not be sufficient to address the pandemic.In a recent article, Fadi El-Jardali, argued that while the pandemic will have grave health and economic consequences for years to come, it brings with it a valuable opportunity to re-envision the role of state and non-state actors in strengthening health systems. The article addressed the need for increased collaboration between state and non-state actors, and the rethinking of existing cooperation models to provide quality healthcare services for all. In this webinar, part of the Chatham House project on the future of the state in the Middle East and North Africa, Dr El-Jardali will discuss how state and non-state actors can collaborate more effectively to address the shortcomings of national health care systems amidst the pandemic and beyond. The article’s author will share insights on the different capacities available in Arab societies that governments can draw upon to ensure that Universal Health Coverage, equity considerations and social justice are at the core of health systems.You can express your interest in attending by following this link.

stem CXCR4-targeted positron emission tomography imaging of central nervous system B-cell lymphoma By jnm.snmjournals.org Published On :: 2020-04-24T14:33:41-07:00 C-X-C chemokine receptor 4 is a transmembrane chemokine receptor involved in growth, survival, and dissemination of cancer, including aggressive B-cell lymphoma. Magnetic resonance imaging (MRI) is the standard imaging technology for central nervous system involvement of B-cell lymphoma and provides high sensitivity but moderate specificity. Therefore, novel molecular and functional imaging strategies are urgently required. Methods: In this proof-of-concept study, 11 patients with lymphoma of the CNS (CNSL, n = 8 primary and n = 3 secondary involvement) were imaged with the CXCR4-directed positron emission tomography (PET) tracer 68Ga-Pentixafor. To evaluate the predictive value of this imaging modality, treatment response, as determined by MRI, was correlated with quantification of CXCR4 expression by 68Ga-Pentixafor PET in vivo before initiation of treatment in 7 of 11 patients. Results: 68Ga-Pentixafor-PET showed excellent contrast characteristics to the surrounding brain parenchyma in all patients with active disease. Furthermore, initial CXCR4 uptake determined by PET correlated with subsequent treatment response as assessed by MRI. Conclusion: 68Ga-Pentixafor-PET represents a novel diagnostic tool for central nervous system lymphoma with potential implications for theranostic approaches as well as response and risk assessment.

stem Radioiodine Ablation of Remaining Thyroid Lobe in Patients with Differentiated Thyroid Cancer Treated by Lobectomy. A systematic review and meta-analysis. By jnm.snmjournals.org Published On :: 2020-04-24T14:33:41-07:00 Purpose: We aimed to conduct a systematic review and meta-analysis of studies reporting the performance of radioactive iodine therapy (131-I therapy) in differentiating thyroid cancer (DTC) patients requiring a completion treatment following lobectomy. We also evaluated the response to 131-I therapy according to 2015ATA guidelines and the adverse events. Methods: A specific search strategy was designed to find articles evaluating the use of I-131 in patients with evidence of DTC after lobectomy. PubMed, CENTRAL, Scopus and Web of Science were searched. The search was updated until January 2020, without language restriction. Data were cross-checked and any discrepancy discussed. A proportion meta-analysis (with 95%CI) was performed using the random-effects model. Meta-regressions on I-131 success were attempted. Results: The pooled success ablation rate was 69% with better results in patients receiving a single administration of about 3.7 GBq; high heterogeneity was found (I2 85%), and publication bias was absent (Egger test: P = 0.57). Incomplete structural responses were recorded in only 14 of 695 (2%) patients enrolled in our analysis. Incomplete biochemical responses were observed in 8 to 24% of patients, with higher rates (24%) in patients receiving low radioiodine activities (~1.1 GBq) and lower rates (from 8 to 18%) in patients receiving higher activities of radioiodine (~3.7 Gbq). Neck pain due to thyroiditis was reported in up to 18% of patients but, in most cases, symptoms resolved after oral paracetamol or a short course of prednisone. Conclusion: Lobar ablation with 131-I is effective especially when high 131I activities are used. However, the rate of incomplete biochemical response to initial treatment appears to be slightly higher than the classical scheme of initial treatment of DTC. "Radioisotopic lobectomy" should be considered for patients with low-to-intermediate risk DTC requiring completion treatment after lobectomy due to specific individual risk factors and/or patient’s preferences.

stem A Quantitative Tri-fluorescent Yeast Two-hybrid System: From Flow Cytometry to In cellula Affinities [Technological Innovation and Resources] By feedproxy.google.com Published On :: 2020-04-01T00:05:32-07:00 We present a technological advancement for the estimation of the affinities of Protein-Protein Interactions (PPIs) in living cells. A novel set of vectors is introduced that enables a quantitative yeast two-hybrid system based on fluorescent fusion proteins. The vectors allow simultaneous quantification of the reaction partners (Bait and Prey) and the reporter at the single-cell level by flow cytometry. We validate the applicability of this system on a small but diverse set of PPIs (eleven protein families from six organisms) with different affinities; the dissociation constants range from 117 pm to 17 μm. After only two hours of reaction, expression of the reporter can be detected even for the weakest PPI. Through a simple gating analysis, it is possible to select only cells with identical expression levels of the reaction partners. As a result of this standardization of expression levels, the mean reporter levels directly reflect the affinities of the studied PPIs. With a set of PPIs with known affinities, it is straightforward to construct an affinity ladder that permits rapid classification of PPIs with thus far unknown affinities. Conventional software can be used for this analysis. To permit automated analysis, we provide a graphical user interface for the Python-based FlowCytometryTools package. Full Article

stem Influencing the social impact of financial systems: alternative strategies By feedproxy.google.com Published On :: Wed, 04 Mar 2020 13:35:39 +0000 4 March 2020 , Volume 96, Number 2 Lee-Anne Sim Read Online The social impact of the global financial crisis brought global and domestic financial systems into public focus. While over the last ten years governments have introduced a range of regulatory reforms, there are still low levels of public trust in financial sectors, and academics continue to express their concerns about financial systems and their desire for more influence. This is particularly the case for those framing their evaluation of the quality of financial systems in terms of social values. This article offers those seeking more influence over the social values of financial systems, a fresh perspective on their available strategic options for influencing outcomes. It argues that they should consider strategies aimed at making allies of financial sectors and regulators in influencing change. The main advantage of these alliance strategies is that they address key constraints to influence, as identified in existing scholarship, which are difficult to relax because they are tied to features inherent in financial systems. By addressing these constraints, alliance strategies could increase the likelihood that financial system outcomes align more closely with their preferred social values. Full Article

The longer term impacts are still being realized and depend heavily on the ability of industry and the government to respond effectively to the direct economic shock caused by the pandemic.Systemic shocks like the COVID-19 pandemic demand immediate responses, but should also encourage governments and industries to re-examine their recovery processes, their resilience and their forward planning. In this webinar, the panellists will discuss the short and long-term impacts of the current crisis and explore how industry can help ensure that the global economy is able to recover from, and build resilience to, future systemic shocks. How do business leaders move from making decisions to reimagining a ‘new normal’ and reforming their practices? What are the critical decisions that businesses should consider when planning for this 'new normal'? And how far can these decisions be based on expected changes to governmental or intergovernmental regulation of different sectors?

stem Let's Emerge From COVID-19 with Stronger Health Systems By feedproxy.google.com Published On :: Thu, 26 Mar 2020 09:33:28 +0000 26 March 2020 Robert Yates Director, Global Health Programme; Executive Director, Centre for Universal Health @yates_rob Heads of state should grasp the opportunity to become universal health heroes to strengthen global health security 2020-03-26-Health-Protest A "Big Insurance: Sick of It" rally in New York City. Photo by Mario Tama/Getty Images. As the COVID-19 pandemic presents the greatest threat to human health in over a century, people turn to their states to resolve the crisis and protect their health, their livelihoods and their future well-being.How leaders perform and respond to the pandemic is likely to define their premiership - and this therefore presents a tremendous opportunity to write themselves into the history books as a great leader, rescuing their people from a crisis. Just as Winston Churchill did in World War Two.Following Churchill’s advice to “never let a good crisis go to waste”, if leaders take decisive action now, they may emerge from the COVID-19 crisis as a national hero. What leaders must do quickly is to mitigate the crisis in a way which has a demonstrable impact on people’s lives.Given the massive shock caused by the pandemic to economies across the world, it is not surprising that heads of state and treasury ministers have implemented enormous economic stimulus packages to protect businesses and jobs – this was to be expected and has been welcome.National heroes can be madeBut, in essence, this remains primarily a health crisis. And one obvious area for leaders to act rapidly is strengthening their nation’s health system to stop the spread of the virus and successfully treat those who have fallen sick. It is perhaps here that leaders have the most to gain - or lose - and where national heroes can be made.This is particularly the case in countries with weak and inequitable health systems, where the poor and vulnerable often fail to access the services they need. One major practical action that leaders can implement immediately is to launch truly universal, publicly-financed health reforms to cover their entire population – not only for COVID-19 services but for all services.This would cost around 1-2% GDP in the short-term but is perfectly affordable in the current economic climate, given some of the massive fiscal stimuluses already being planned (for example, the UK is spending 15% GDP to tackle COVID-19).Within one to two years, this financing would enable governments to implement radical supply side reforms including scaling up health workforces, increasing the supply of essential medicines, diagnostics and vaccines and building new infrastructure. It would also enable them to remove health service user fees which currently exclude hundreds of millions of people worldwide from essential healthcare. Worldwide these policies have proven to be effective, efficient, equitable and extremely popular.And there is plenty of precedent for such a move. Universal health reform is exactly what political leaders did in the UK, France and Japan as post-conflict states emerging from World War Two. It is also the policy President Kagame launched in the aftermath of the genocide in Rwanda, as did Prime Minister Thaksin in Thailand after the Asian Financial Crisis in 2002, and the Chinese leadership did following the SARS crisis, also in 2003.In China’s case, reform involved re-socialising the health financing system using around 2% GDP in tax financing to increase health insurance coverage from a low level of one-third right up to 96% of the population.All these universal health coverage (UHC) reforms delivered massive health and economic benefits to the people - just what is needed now to tackle COVID-19 - and tremendous political benefits to the leaders that implemented them.When considering the current COVID-19 crisis, this strategy would be particularly relevant for countries underperforming on health coverage and whose health systems are more likely to be overwhelmed if flooded with a surge of patients, such as India, Pakistan, Bangladesh, Myanmar, Indonesia and most of sub-Saharan Africa, where many governments spend less than 1% of their GDP on health and most people have to buy services over the counter.But also the two OECD countries without a universal health system – the United States and Ireland – are seeing the threat of COVID-19 already fuelling the debate about the need to create national, publicly-financed health system. And the presidents of South Africa, Kenya and Indonesia have already committed their governments to eventually reach full population coverage anyway, and so may use this crisis to accelerate their own universal reforms. Although difficult to predict which leaders are likely to grasp the opportunity, if some of these countries now fast-track nationwide UHC, at least something good will be coming from the crisis, something which will benefit their people forever. And ensuring everyone accesses the services they need, including public health and preventive services, also provides the best protection against any future outbreaks becoming epidemics.Every night large audiences are tuning in to press briefings fronted by their heads of state hungry for the latest update on the crisis and to get reassurance that their government’s strategy will bring the salvation they desperately need. To truly improve health security for people across the world, becoming UHC heroes could be the best strategic decision political leaders ever make. Full Article
stem Dysregulation of Exosome Cargo by Mutant Tau Expressed in Human-Induced Pluripotent Stem Cell (iPSC) Neurons Revealed by Proteomics Analyses [Research] By feedproxy.google.com Published On :: 2020-04-15T09:35:42-07:00 Accumulation and propagation of hyperphosphorylated tau (p-tau) is a common neuropathological hallmark associated with neurodegeneration of Alzheimer's disease (AD), frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), and related tauopathies. Extracellular vesicles, specifically exosomes, have recently been demonstrated to participate in mediating tau propagation in brain. Exosomes produced by human induced pluripotent stem cell (iPSC)-derived neurons expressing mutant Tau (mTau), containing the P301L and V337M Tau mutations of FTDP-17, possess the ability to propagate p-tau pathology after injection into mouse brain. To gain an understanding of the mTau exosome cargo involved in tau pathogenesis, these pathogenic exosomes were analyzed by proteomics and bioinformatics. The data showed that mTau expression dysregulates the exosome proteome to result in (1) proteins uniquely present only in mTau, and not control exosomes, (2) the absence of proteins in mTau exosomes, uniquely present in control exosomes, and (3) shared proteins which were significantly up-regulated or down-regulated in mTau compared to control exosomes. Notably, mTau exosomes (not control exosomes) contain ANP32A (also known as I1PP2A), an endogenous inhibitor of the PP2A phosphatase which regulates the phosphorylation state of p-tau. Several of the mTau exosome-specific proteins have been shown to participate in AD mechanisms involving lysosomes, inflammation, secretases, and related processes. Furthermore, the mTau exosomes lacked a substantial portion of proteins present in control exosomes involved in pathways of localization, vesicle transport, and protein binding functions. The shared proteins present in both mTau and control exosomes represented exosome functions of vesicle-mediated transport, exocytosis, and secretion processes. These data illustrate mTau as a dynamic regulator of the biogenesis of exosomes to result in acquisition, deletion, and up- or down-regulation of protein cargo to result in pathogenic mTau exosomes capable of in vivo propagation of p-tau neuropathology in mouse brain.

stem Russian Economic Policy and the Russian Economic System: Stability Versus Growth By feedproxy.google.com Published On :: Tue, 17 Dec 2019 16:50:53 +0000 17 December 2019 How is it possible for the directors of the Russian economy to pursue an orthodox stabilization policy with a great measure of success and yet to have achieved so little to stem the growth slowdown? This paper examines the reasons for the divergence in economic management.

Photo: Getty Images. SummaryRussia’s economic management is currently praised for its achievement of macroeconomic stability. Inflation has been brought down; the budget is in surplus; national debt is low; and the reserves are ample. At the same time, there is much criticism of the failure at present to secure more than very slow economic growth.The macro-stabilization of 2014–18 was of a conventional, ‘liberal’ kind. Public spending was cut, and a budget rule was introduced that (so far) has weakened the link between increases in oil prices and increases in budgetary expenditure. The austerity campaign was harsh. Pensioners, the military, regional budgets and business all lost out, but in reality put up little resistance. The austerity drive was facilitated by the autocratic nature of the regime.The growth slowdown dates from 2012, and cannot simply be blamed on falls in the oil price and sanctions. Rapid growth in 1999–2008 consisted in large part of recovery from the deep recession of the 1990s and the initial development of a services sector. These sources of growth are no longer available; investment is low; and the labour force is declining. The Western world also has a slow growth problem, but at a higher level of per capita output. In Russia, private investment and competition are inhibited by an intrusive and corrupt state. If the rule of law were in place, the economy would perform better in the long run. That would require a profound reform of formal and informal institutions.The leadership wants faster growth, but has powerful incentives not to embark on systemic reform. Even the pragmatic ministers of the ‘economic bloc’ of government, who understand the problem, share this interest in maintaining the status quo. Growth is thus being sought through a highly ambitious programme, in 2018–24, of ‘national projects’, state-led and largely state-financed. This is already running into difficulties.The contrast between successful stabilization and a (so far) unsuccessful growth strategy illustrates the difference between policymaking within a given system and reform of that system. Systemic reform brings with it more potential unintended consequences than do changes in policy. In the case of Russia, movement towards a rule of law could destabilize the social and political system. It is therefore unlikely to be attempted.

stem Model systems for studying the assembly, trafficking, and secretion of apoB lipoproteins using fluorescent fusion proteins [Research Articles] By feedproxy.google.com Published On :: 2020-03-01T00:06:33-08:00 apoB exists as apoB100 and apoB48, which are mainly found in hepatic VLDLs and intestinal chylomicrons, respectively. Elevated plasma levels of apoB-containing lipoproteins (Blps) contribute to coronary artery disease, diabetes, and other cardiometabolic conditions. Studying the mechanisms that drive the assembly, intracellular trafficking, secretion, and function of Blps remains challenging. Our understanding of the intracellular and intraorganism trafficking of Blps can be greatly enhanced, however, with the availability of fusion proteins that can help visualize Blp transport within cells and between tissues. We designed three plasmids expressing human apoB fluorescent fusion proteins: apoB48-GFP, apoB100-GFP, and apoB48-mCherry. In Cos-7 cells, transiently expressed fluorescent apoB proteins colocalized with calnexin and were only secreted if cells were cotransfected with microsomal triglyceride transfer protein. The secreted apoB-fusion proteins retained the fluorescent protein and were secreted as lipoproteins with flotation densities similar to plasma HDL and LDL. In a rat hepatoma McA-RH7777 cell line, the human apoB100 fusion protein was secreted as VLDL- and LDL-sized particles, and the apoB48 fusion proteins were secreted as LDL- and HDL-sized particles. To monitor lipoprotein trafficking in vivo, the apoB48-mCherry construct was transiently expressed in zebrafish larvae and was detected throughout the liver. These experiments show that the addition of fluorescent proteins to the C terminus of apoB does not disrupt their assembly, localization, secretion, or endocytosis. The availability of fluorescently labeled apoB proteins will facilitate the exploration of the assembly, degradation, and transport of Blps and help to identify novel compounds that interfere with these processes via high-throughput screening.

As Trump faces possible impeachment in the House of Representatives, what – if any – influence might his combative approach towards legal battles have on the political proceedings?Drawing on New York attorney James Zirin’s new book, Plaintiff in Chief, this event examines the relationship between President Trump’s litigation history and his approach to the presidency.How has the American legal system facilitated Trump’s attitude towards litigation? How can his litigation toolkit be countered?And what impact has the president’s approach to litigation had on the domestic and global reputation of the American legal system and the office of the president as accountable and credible institutions?

stem Russian Economic Policy and the Russian Economic System: Stability Versus Growth By feedproxy.google.com Published On :: Tue, 17 Dec 2019 16:50:53 +0000 17 December 2019 How is it possible for the directors of the Russian economy to pursue an orthodox stabilization policy with a great measure of success and yet to have achieved so little to stem the growth slowdown? This paper examines the reasons for the divergence in economic management.

Photo: Getty Images. SummaryRussia’s economic management is currently praised for its achievement of macroeconomic stability. Inflation has been brought down; the budget is in surplus; national debt is low; and the reserves are ample. At the same time, there is much criticism of the failure at present to secure more than very slow economic growth.The macro-stabilization of 2014–18 was of a conventional, ‘liberal’ kind. Public spending was cut, and a budget rule was introduced that (so far) has weakened the link between increases in oil prices and increases in budgetary expenditure. The austerity campaign was harsh. Pensioners, the military, regional budgets and business all lost out, but in reality put up little resistance. The austerity drive was facilitated by the autocratic nature of the regime.The growth slowdown dates from 2012, and cannot simply be blamed on falls in the oil price and sanctions. Rapid growth in 1999–2008 consisted in large part of recovery from the deep recession of the 1990s and the initial development of a services sector. These sources of growth are no longer available; investment is low; and the labour force is declining. The Western world also has a slow growth problem, but at a higher level of per capita output. In Russia, private investment and competition are inhibited by an intrusive and corrupt state. If the rule of law were in place, the economy would perform better in the long run. That would require a profound reform of formal and informal institutions.The leadership wants faster growth, but has powerful incentives not to embark on systemic reform. Even the pragmatic ministers of the ‘economic bloc’ of government, who understand the problem, share this interest in maintaining the status quo. Growth is thus being sought through a highly ambitious programme, in 2018–24, of ‘national projects’, state-led and largely state-financed. This is already running into difficulties.The contrast between successful stabilization and a (so far) unsuccessful growth strategy illustrates the difference between policymaking within a given system and reform of that system. Systemic reform brings with it more potential unintended consequences than do changes in policy. In the case of Russia, movement towards a rule of law could destabilize the social and political system. It is therefore unlikely to be attempted.

stem Insulin-Deficient Diabetic Condition Upregulates the Insulin-Secreting Capacity of Human Induced Pluripotent Stem Cell-Derived Pancreatic Endocrine Progenitor Cells After Implantation in Mice By diabetes.diabetesjournals.org Published On :: 2020-03-20T11:50:28-07:00 The host environment is a crucial factor for considering the transplant of stem cell–derived immature pancreatic cells in patients with type 1 diabetes. Here, we investigated the effect of insulin (INS)-deficient diabetes on the fate of immature pancreatic endocrine cell grafts and the underlying mechanisms. Human induced pluripotent stem cell–derived pancreatic endocrine progenitor cells (EPCs), which contained a high proportion of chromogranin A+ NK6 homeobox 1+ cells and very few INS+ cells, were used. When the EPCs were implanted under the kidney capsule in immunodeficient mice, INS-deficient diabetes accelerated increase in plasma human C-peptide, a marker of graft-derived INS secretion. The acceleration was suppressed by INS infusion but not affected by partial attenuation of hyperglycemia by dapagliflozin, an INS-independent glucose-lowering agent. Immunohistochemical analyses indicated that the grafts from diabetic mice contained more endocrine cells including proliferative INS-producing cells compared with that from nondiabetic mice, despite no difference in whole graft mass between the two groups. These data suggest that INS-deficient diabetes upregulates the INS-secreting capacity of EPC grafts by increasing the number of endocrine cells including INS-producing cells without changing the graft mass. These findings provide useful insights into postoperative diabetic care for cell therapy using stem cell–derived pancreatic cells. Full Article

stem Major Improvement in Wound Healing Through Pharmacologic Mobilization of Stem Cells in Severely Diabetic Rats By diabetes.diabetesjournals.org Published On :: 2020-03-20T11:50:29-07:00 Current therapeutic strategies for diabetic foot ulcer (DFU) have focused on developing topical healing agents, but few agents have controlled prospective data to support their effectiveness in promoting wound healing. We tested a stem cell mobilizing therapy for DFU using a combination of AMD3100 and low-dose FK506 (tacrolimus) (AF) in streptozocin-induced type 1 diabetic (T1DM) rats and type 2 diabetic Goto-Kakizaki (GK) rats that had developed peripheral artery disease and neuropathy. Here, we show that the time for healing back wounds in T1DM rats was reduced from 27 to 19 days, and the foot wound healing time was reduced from 25 to 20 days by treatment with AF (subcutaneously, every other day). Similarly, in GK rats treated with AF, the healing time on back wounds was reduced from 26 to 21 days. Further, this shortened healing time was accompanied by reduced scar and by regeneration of hair follicles. We found that AF therapy mobilized and recruited bone marrow–derived CD133+ and CD34+ endothelial progenitor cells and Ym1/2+ M2 macrophages into the wound sites, associated with enhanced capillary and hair follicle neogenesis. Moreover, AF therapy improved microcirculation in diabetic and neuropathic feet in GK rats. This study provides a novel systemic therapy for healing DFU. Full Article

stem Diagnostic Accuracy of PET Tracers for the Differentiation of Tumor Progression from Treatment-Related Changes in High-Grade Glioma: A Systematic Review and Metaanalysis By jnm.snmjournals.org Published On :: 2020-04-01T06:00:28-07:00 Posttreatment high-grade gliomas are usually monitored with contrast-enhanced MRI, but its diagnostic accuracy is limited as it cannot adequately distinguish between true tumor progression and treatment-related changes. According to recent Response Assessment in Neuro-Oncology recommendations, PET overcomes this limitation. However, it is currently unknown which tracer yields the best results. Therefore, a systematic review and metaanalysis were performed to compare the diagnostic accuracy of the different PET tracers in differentiating tumor progression from treatment-related changes in high-grade glioma patients. Methods: PubMed, Web of Science, and Embase were searched systematically. Study selection, data extraction, and quality assessment were performed independently by 2 authors. Metaanalysis was performed using a bivariate random-effects model when at least 5 studies were included. Results: The systematic review included 39 studies (11 tracers). 18F-FDG (12 studies, 171 lesions) showed a pooled sensitivity and specificity of 84% (95% confidence interval, 72%–92%) and 84% (95% confidence interval, 69%–93%), respectively. O-(2-18F-fluoroethyl)-l-tyrosine (18F-FET) (7 studies, 172 lesions) demonstrated a sensitivity of 90% (95% confidence interval, 81%–95%) and specificity of 85% (95% confidence interval, 71%–93%). For S-11C-methyl)-l-methionine (11C-MET) (8 studies, 151 lesions), sensitivity was 93% (95% confidence interval, 80%–98%) and specificity was 82% (95% confidence interval, 68%–91%). The numbers of included studies for the other tracers were too low to combine, but sensitivity and specificity ranged between 93%–100% and 0%–100%, respectively, for 18F-FLT; 85%–100% and 72%–100%, respectively, for 3,4-dihydroxy-6-18F-fluoro-l-phenylalanine (18F-FDOPA); and 100% and 70%–88%, respectively, for 11C-choline. Conclusion: 18F-FET and 11C-MET, both amino-acid tracers, showed a comparably higher sensitivity than 18F-FDG in the differentiation between tumor progression and treatment-related changes in high-grade glioma patients. The evidence for other tracers is limited; thus, 18F-FET and 11C-MET are preferred when available. Our results support the incorporation of amino-acid PET tracers for the treatment evaluation of high-grade gliomas. Full Article

Meeting future global food security requirements is not just about quantity; it is also about meeting growing needs in a way that safeguards human as well as planetary health. But national priorities and policies often remain out of sync with aspirations for more sustainable and healthy food systems.International trade and trade policies play an ambiguous role in the current food system. With 80 per cent of the world’s population depending on imports to meet at least part of their food and nutritional requirements, trade has a unique function in offsetting imbalances between supply and demand. However, in the absence of effective regulatory frameworks or pricing frameworks that internalize environmental, social or health costs, trade can exacerbate and globalize challenges associated with food production and land use trends such as deforestation, land degradation, greenhouse gas emissions, biodiversity loss and the shift to unhealthy diets.Over the last two decades, trade in agricultural products (excluding intra-EU flows) has more than tripled in value, to reach $1.33 trillion. The geography of global food trade flows has also shifted, primarily towards South–South trade, which now accounts for roughly a quarter of total agricultural trade flows. The nature of global trade has changed drastically, with traditional exports such as wheat and coffee growing slowly at around 2 per cent per year, while products such as palm oil, fruit juice, soft drinks and other processed products have grown at 8 per cent or more annually.This overall increase in trade in agricultural products raises questions about the growing utilization of resources, such as water or soil nutrients, that are embedded in those products through production and processing. Trade itself also causes negative environmental impacts, starting with greenhouse gas emissions associated with transport and storage. If the environmental cost associated with production and trade is not reflected in the final price of goods, trade may accelerate the depletion of resources or their unsustainable use.It is critical to ensure that trade policy options pursued by producing and consuming countries alike will support a transition to more sustainable and healthier food and land use systems. The first step in addressing trade-related food systems challenges must involve rebuilding trust among policy actors. There is a need for new spaces for informal dialogue among actors, and ‘soft’ governance mechanisms that can help rebuild consensus on the best ways forward. Meeting these challenges also requires an appreciation of the complex interactions between sectoral policies (e.g. on water, land, food, etc.) and their multiple interfaces with trade policies. Conditioning the use of subsidies on their sustainability and/or health impacts encourages the delivery of essential public goods in ways that are consistent with sustainability and health goals. A first step therefore is the removal of perverse incentives (e.g. subsidies encouraging the overuse of fertilizers or pesticides or the overproduction of certain commodities, as well as certain biofuels subsidies) and replacing them with market-correcting subsidies.Trade facilitation measures for fruits and vegetables that are aimed at easing transit at the border, by cutting unnecessary bureaucracy and reducing waiting times, can improve their availability, reduce costs and improve food quality and safety for consumers. Similarly, measures aimed at improving sustainable cold storage and upgrading value chains can support better diets and consumption by increasing the availability of fresh produce on markets, especially in developing countries.A global food stamps programme developed through the G20 and facilitated by the UN’s food agencies could address purchasing power imbalances and tackle malnutrition in developing countries. If carefully designed, such ‘safety net’ schemes can not only contribute to improving calorific intakes but also help deliver more balanced and healthier diets. Careful attention must be given to how such a scheme would work in practice, building on experience to date with similar initiatives.Integrating the notion of sustainable food and inputs trade in the post-2020 global biodiversity framework can help to deliver more sustainable and healthier food and land use systems. This could be achieved by likeminded countries introducing a set of goals or targets aimed at mitigating the role of trade in placing indirect pressure on biodiversity, and to encourage trade in biodiversity-based products including natural ingredients produced ethically and following sustainability principles and criteria.An SDG-oriented agenda for agricultural trade is needed. It could be formed by countries seeking to remove perverse incentives, guaranteeing a safe harbour for market-correcting measures, clarifying existing rules and establishing plurilateral negotiations among subsets of the WTO membership, or sectoral approaches, to address specific challenges.Greenhouse gas emissions resulting from trade need to be addressed. Governments could seek to achieve this through ensuring the carbon neutrality of existing and new trade deals, either by connecting carbon markets among contracting parties or by developing joint initiatives to tax international maritime and air transport emissions.

stem How Qatar’s Food System Has Adapted to the Blockade By feedproxy.google.com Published On :: Thu, 14 Nov 2019 14:43:46 +0000 14 November 2019 Laura Wellesley Research Fellow, Energy, Environment and Resources Programme @laurawellesley Two-and-a-half years on from the imposition of a trade blockade against Qatar by the Arab Quartet, Qatar’s food system has undergone a remarkable transformation – but it is one that brings new risks to Qatar’s future food and resource security. 2019-11-14-QatarCows.jpg Cows are are fed at a dairy factory at Baladna farm in al-Khor, Qatar. Photo: Karim Jaafar/AFP via Getty Images. Earlier this month, Sheikh Tamim – the emir of Qatar – hailed the country’s success in overcoming the impacts of the embargo levied by the so-called Arab Quartet – Bahrain, Egypt, Saudi Arabia and the United Arab Emirates (UAE). Qatar will post a budget surplus for the first time in three years, and the country’s long-term plan for economic diversification has taken great strides, according to the emir. Key among the achievements cited was the advancement of Qatar’s domestic food industry.When the blockade was introduced in June 2017, it threw the vulnerability of Qatar’s domestic food supply to outside interruption into sharp relief. Qatar is poorly suited to growing food. The desert country ranks as the most water-stressed in the world. As one of the hottest, most arid countries in the world, trade is critical to feeding the nation; over 90 per cent of its food supply is imported.Most of Qatar’s cereal imports – including 80 per cent of its wheat supply – arrive by sea from exporters including India, Russia and Australia. Sitting on the eastern edge of the Persian Gulf, Qatar’s only maritime gateway to the world is the Strait of Hormuz. This narrow body of water can, as events this summer have shown, be disrupted by geopolitical events. But for 40 per cent of overall food imports, overland trade from Saudi Arabia was Qatar’s primary supply channel before June 2017 – particularly so for dairy products and fresh fruit and vegetables coming from the EU, Turkey and Jordan.The abrupt closure of Saudi Arabia’s borders prompted significant private investment in Qatar’s own food industry; domestic production has reportedly increased four-fold since the blockade was introduced. Prior to the blockade, Qatar imported 85 per cent of its vegetables; it now hopes to produce 60 per cent within the next three years. Perhaps even more remarkably, the country is now self-sufficient in dairy, having previously relied on imports for 72 per cent of its supply.This progress has come at a cost. Qatar’s booming domestic industry is highly resource-intensive. To fill the gap in the dairy sector, Baladna – the country’s principal dairy producer – imported around 18,000 Holstein dairy cows from the EU and US. The company is thriving; in June of this year, it made its first dairy exports.But the desert is not a natural environment for these cows; they must be kept indoors, at temperatures around 15°C cooler than the outside air, and misted with water to prevent overheating. The cooling systems are a huge drain on local resources. Each dairy cow requires an average of 185 gallons of water a day, almost twice the volume used by the average Qatari household. The majority of this water comes from oil- or gas-powered desalination plants; the cooling systems themselves run on gas-fired electricity.Qatar has traditionally invested in production overseas – particularly in Sudan and Tanzania – to secure its fodder supply, but the government has plans to become self-sufficient in fodder crops such as lucerne (alfalfa) and Rhodes grass. This will require irrigation on a vast scale. Qatar’s farmland is mostly located in the north of the country where it benefits from aquifers; fodder production already accounts for half of the groundwater extracted for use in agriculture.Despite commitments made under the National Food Security Programme to improving the water efficiency of Qatar’s food production, the rate of draw-down of these aquifers exceeds their recharge rates. Overexploitation has resulted in saline intrusion, threatening their long-term viability. With 92 per cent of all extracted groundwater given to farmers free of charge, there is little incentive for economizing on its use.Increasing production will also likely mean increasing fertilizer use; rates of fertilizer use in Qatar are among the highest in the world, second only to those in Singapore.Both government and industry are taking small steps to ‘green’ the country’s food production. Certain local authorities plan to ban the use of groundwater for fodder production by 2025, requiring producers to use treated sewage water instead and reserving the use of groundwater for crop production.A number of companies are also adopting so-called ‘circular’ practices to achieve more efficienct resource use; Agrico, a major vegetable producer, has expanded its organic hydroponics operations, a move the company reports has led to a 90 per cent reduction in water use. But, with a target to produce up to 50 per cent of Qatar’s fresh food supply domestically within just a few years, scattered examples of resource-saving strategies will not be enough to mitigate the rise in water demand.As Qatar looks to continue growing its food industry in the wake of the blockade, it is from Saudi Arabia – ironic though it may be – that Qatar stands to learn important lessons.Saudi Arabia’s scaling up of domestic wheat production – initially to achieve self-sufficiency and then to support a prosperous export industry – was ultimately a failed effort. The unsustainable extraction of groundwater – fuelled by generous subsidies for wheat producers and the nominal cost of diesel for pumping – brought the country’s water table to the brink of collapse, and the government was forced to make a dramatic U-turn, reducing then removing the subsidies and shrinking its wheat sector.The UAE also provides an instructive example for how domestic food production may be supported – this time positive. This summer, the Department of Environment in Abu Dhabi announced its Recycled Water Policy, laying out a policy framework to promote and facilitate reused water across all major sectors, including agriculture.Back in 2014, the Ministry of Climate Change and Environment set hydroponics as a key priority, launching a 100 million Emirati dirham fund to incentivize and support farmers establishing hydroponic farms. And the International Center for Biosaline Agriculture, based in Dubai and supported by the UAE government, undertakes pioneering research into sustainable food production in saline environments.On the face of it, Qatar has indeed bounced back from the blockade. As and when cross-border trade is re-established with Saudi Arabia, Qatar will boast a more diverse – and more resilient – network of trade relationships than it did prior to June 2017.In addition to investment in domestic food production, the blockade also provoked a rapid recalibration of Qatar’s trade relationships. Allies in the region – most notably Turkey and Iran – were quick to come to Qatar’s assistance, delivering fresh produce by air. Since then, Qatar has scaled up its trading relationship with both countries.It has also leveraged its position as the world’s largest exporter of liquid natural gas to establish new maritime trade lines with major food exporters, including India. Should tensions spike again in the future, it will be in a stronger position to weather the storm.But, in the absence of a commitment to support the widespread adoption of circular agricultural technologies and practices, Qatar’s commitment to increasing its self-sufficiency and expanding its domestic production could ultimately undermine its long-term food security.Rising average temperatures and increasingly frequent extreme weather events – like the heatwave in 2010 when temperatures soared to over 50°C – will exacerbate already high resource stress in the country. Unsustainable exploitation of finite land, water and energy reserves will limit the country’s long-term capacity to produce food and weaken its ability to withstand future disruptions to regional and international supply channels.As Qatar continues in its efforts to secure a reliable food supply, it would do well to heed the experience of its neighbours, be they friend or foe.
