cr Effects of Pioglitazone on Glucose-Dependent Insulinotropic Polypeptide-Mediated Insulin Secretion and Adipocyte Receptor Expression in Patients With Type 2 Diabetes By diabetes.diabetesjournals.org Published On :: 2020-01-20T12:00:25-08:00 Incretin hormone dysregulation contributes to reduced insulin secretion and hyperglycemia in patients with type 2 diabetes mellitus (T2DM). Resistance to glucose-dependent insulinotropic polypeptide (GIP) action may occur through desensitization or downregulation of β-cell GIP receptors (GIP-R). Studies in rodents and cell lines show GIP-R expression can be regulated through peroxisome proliferator–activated receptor (PPAR) response elements (PPREs). Whether this occurs in humans is unknown. To test this, we conducted a randomized, double-blind, placebo-controlled trial of pioglitazone therapy on GIP-mediated insulin secretion and adipocyte GIP-R expression in subjects with well-controlled T2DM. Insulin sensitivity improved, but the insulinotropic effect of infused GIP was unchanged following 12 weeks of pioglitazone treatment. In parallel, we observed increased GIP-R mRNA expression in subcutaneous abdominal adipocytes from subjects treated with pioglitazone. Treatment of cultured human adipocytes with troglitazone increased PPAR binding to GIP-R PPREs. These results show PPAR agonists regulate GIP-R expression through PPREs in human adipocytes, but suggest this mechanism is not important for regulation of the insulinotropic effect of GIP in subjects with T2DM. Because GIP has antilipolytic and lipogenic effects in adipocytes, the increased GIP-R expression may mediate accretion of fat in patients with T2DM treated with PPAR agonists. Full Article
cr Mitochondrial Proton Leak Regulated by Cyclophilin D Elevates Insulin Secretion in Islets at Nonstimulatory Glucose Levels By diabetes.diabetesjournals.org Published On :: 2020-01-20T12:00:25-08:00 Fasting hyperinsulinemia precedes the development of type 2 diabetes. However, it is unclear whether fasting insulin hypersecretion is a primary driver of insulin resistance or a consequence of the progressive increase in fasting glycemia induced by insulin resistance in the prediabetic state. Herein, we have discovered a mechanism that specifically regulates non–glucose-stimulated insulin secretion (NGSIS) in pancreatic islets that is activated by nonesterified free fatty acids, the major fuel used by β-cells during fasting. We show that the mitochondrial permeability transition pore regulator cyclophilin D (CypD) promotes NGSIS, but not glucose-stimulated insulin secretion, by increasing mitochondrial proton leak. Islets from prediabetic obese mice show significantly higher CypD-dependent proton leak and NGSIS compared with lean mice. Proton leak–mediated NGSIS is conserved in human islets and is stimulated by exposure to nonesterified free fatty acids at concentrations observed in obese subjects. Mechanistically, proton leak activates islet NGSIS independently of mitochondrial ATP synthesis but ultimately requires closure of the KATP channel. In summary, we have described a novel nonesterified free fatty acid–stimulated pathway that selectively drives pancreatic islet NGSIS, which may be therapeutically exploited as an alternative way to halt fasting hyperinsulinemia and the progression of type 2 diabetes.

cr The Novel Adipokine Gremlin 1 Antagonizes Insulin Action and Is Increased in Type 2 Diabetes and NAFLD/NASH By diabetes.diabetesjournals.org Published On :: 2020-02-20T11:55:30-08:00 The BMP2/4 antagonist and novel adipokine Gremlin 1 is highly expressed in human adipose cells and increased in hypertrophic obesity. As a secreted antagonist, it inhibits the effect of BMP2/4 on adipose precursor cell commitment/differentiation. We examined mRNA levels of Gremlin 1 in key target tissues for insulin and also measured tissue and serum levels in several carefully phenotyped human cohorts. Gremlin 1 expression was high in adipose tissue, higher in visceral than in subcutaneous tissue, increased in obesity, and further increased in type 2 diabetes (T2D). A similar high expression was seen in liver biopsies, but expression was considerably lower in skeletal muscles. Serum levels were increased in obesity but most prominently in T2D. Transcriptional activation in both adipose tissue and liver as well as serum levels were strongly associated with markers of insulin resistance in vivo (euglycemic clamps and HOMA of insulin resistance), and the presence of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). We also found Gremlin 1 to antagonize insulin signaling and action in human primary adipocytes, skeletal muscle, and liver cells. Thus, Gremlin 1 is a novel secreted insulin antagonist and biomarker as well as a potential therapeutic target in obesity and its complications T2D and NAFLD/NASH. Full Article
cr A Single Bout of One-Legged Exercise to Local Exhaustion Decreases Insulin Action in Nonexercised Muscle Leading to Decreased Whole-Body Insulin Action By diabetes.diabetesjournals.org Published On :: 2020-03-20T11:50:28-07:00 A single bout of exercise enhances insulin action in the exercised muscle. However, not all human studies find that this translates into increased whole-body insulin action, suggesting that insulin action in rested muscle or other organs may be decreased by exercise. To investigate this, eight healthy men underwent a euglycemic-hyperinsulinemic clamp on 2 separate days: one day with prior one-legged knee-extensor exercise to local exhaustion (~2.5 h) and another day without exercise. Whole-body glucose disposal was ~18% lower on the exercise day as compared with the resting day due to decreased (~37%) insulin-stimulated glucose uptake in the nonexercised muscle. Insulin signaling at the level of Akt2 was impaired in the nonexercised muscle on the exercise day, suggesting that decreased insulin action in nonexercised muscle may reduce GLUT4 translocation in response to insulin. Thus, the effect of a single bout of exercise on whole-body insulin action depends on the balance between local effects increasing and systemic effects decreasing insulin action. Physiologically, this mechanism may serve to direct glucose into the muscles in need of glycogen replenishment. For insulin-treated patients, this complex relationship may explain the difficulties in predicting the adequate insulin dose for maintaining glucose homeostasis following physical activity.

cr Bariatric Surgery Rapidly Decreases Cardiac Dietary Fatty Acid Partitioning and Hepatic Insulin Resistance Through Increased Intra-abdominal Adipose Tissue Storage and Reduced Spillover in Type 2 Diabetes By diabetes.diabetesjournals.org Published On :: 2020-03-20T11:50:28-07:00 Reduced storage of dietary fatty acids (DFAs) in abdominal adipose tissues with enhanced cardiac partitioning has been shown in subjects with type 2 diabetes (T2D) and prediabetes. We measured DFA metabolism and organ partitioning using positron emission tomography with oral and intravenous long-chain fatty acid and glucose tracers during a standard liquid meal in 12 obese subjects with T2D before and 8–12 days after bariatric surgery (sleeve gastrectomy or sleeve gastrectomy and biliopancreatic diversion with duodenal switch). Bariatric surgery reduced cardiac DFA uptake from a median (standard uptake value [SUV]) 1.75 (interquartile range 1.39–2.57) before to 1.09 (1.04–1.53) after surgery (P = 0.01) and systemic DFA spillover from 56.7 mmol before to 24.7 mmol over 6 h after meal intake after surgery (P = 0.01), with a significant increase in intra-abdominal adipose tissue DFA uptake from 0.15 (0.04–0.31] before to 0.49 (0.20–0.59) SUV after surgery (P = 0.008). Hepatic insulin resistance was significantly reduced in close association with increased DFA storage in intra-abdominal adipose tissues (r = –0.79, P = 0.05) and reduced DFA spillover (r = 0.76, P = 0.01). We conclude that bariatric surgery in subjects with T2D rapidly reduces cardiac DFA partitioning and hepatic insulin resistance at least in part through increased intra-abdominal DFA storage and reduced spillover.

cr Understanding Diabetic Neuropathy--From Subclinical Nerve Lesions to Severe Nerve Fiber Deficits: A Cross-Sectional Study in Patients With Type 2 Diabetes and Healthy Control Subjects By diabetes.diabetesjournals.org Published On :: 2020-02-20T11:55:30-08:00 Studies on magnetic resonance neurography (MRN) in diabetic polyneuropathy (DPN) have found proximal sciatic nerve lesions. The aim of this study was to evaluate the functional relevance of sciatic nerve lesions in DPN, with the expectation of correlations with the impairment of large-fiber function. Sixty-one patients with type 2 diabetes (48 with and 13 without DPN) and 12 control subjects were enrolled and underwent MRN, quantitative sensory testing, and electrophysiological examinations. There were differences in mechanical detection (Aβ fibers) and mechanical pain (A fibers) but not in thermal pain and thermal detection clusters (C fibers) among the groups. Lesion load correlated with lower Aα-, Aβ-, and A-fiber but not with C-fiber function in all participants. Patients with lower function showed a higher load of nerve lesions than patients with elevated function or no measurable deficit despite apparent DPN. Longer diabetes duration was associated with higher lesion load in patients with DPN, suggesting that nerve lesions in DPN may accumulate over time and become clinically relevant once a critical amount of nerve fascicles is affected. Moreover, MRN is an objective method for determining lower function mainly in medium and large fibers in DPN. Full Article
cr Inhibition of NFAT Signaling Restores Microvascular Endothelial Function in Diabetic Mice By diabetes.diabetesjournals.org Published On :: 2020-02-20T11:55:30-08:00 Central to the development of diabetic macro- and microvascular disease is endothelial dysfunction, which appears well before any clinical sign but, importantly, is potentially reversible. We previously demonstrated that hyperglycemia activates nuclear factor of activated T cells (NFAT) in conduit and medium-sized resistance arteries and that NFAT blockade abolishes diabetes-driven aggravation of atherosclerosis. In this study, we test whether NFAT plays a role in the development of endothelial dysfunction in diabetes. NFAT-dependent transcriptional activity was elevated in skin microvessels of diabetic Akita (Ins2+/–) mice when compared with nondiabetic littermates. Treatment of diabetic mice with the NFAT blocker A-285222 reduced NFATc3 nuclear accumulation and NFAT-luciferase transcriptional activity in skin microvessels, resulting in improved microvascular function, as assessed by laser Doppler imaging and iontophoresis of acetylcholine and localized heating. This improvement was abolished by pretreatment with the nitric oxide (NO) synthase inhibitor l-NG-nitro-l-arginine methyl ester, while iontophoresis of the NO donor sodium nitroprusside eliminated the observed differences. A-285222 treatment enhanced dermis endothelial NO synthase expression and plasma NO levels of diabetic mice. It also prevented induction of inflammatory cytokines interleukin-6 and osteopontin, lowered plasma endothelin-1 and blood pressure, and improved mouse survival without affecting blood glucose. In vivo inhibition of NFAT may represent a novel therapeutic modality to preserve endothelial function in diabetes. Full Article
cr Troponin T Parallels Structural Nerve Damage in Type 2 Diabetes: A Cross-sectional Study Using Magnetic Resonance Neurography By diabetes.diabetesjournals.org Published On :: 2020-03-20T11:50:29-07:00 Clinical studies have suggested that changes in peripheral nerve microcirculation may contribute to nerve damage in diabetic polyneuropathy (DN). High-sensitivity troponin T (hsTNT) assays have been recently shown to provide predictive values for both cardiac and peripheral microangiopathy in type 2 diabetes (T2D). This study investigated the association of sciatic nerve structural damage in 3 Tesla (3T) magnetic resonance neurography (MRN) with hsTNT and N-terminal pro-brain natriuretic peptide serum levels in patients with T2D. MRN at 3T was performed in 51 patients with T2D (23 without DN, 28 with DN) and 10 control subjects without diabetes. The sciatic nerve’s fractional anisotropy (FA), a marker of structural nerve integrity, was correlated with clinical, electrophysiological, and serological data. In patients with T2D, hsTNT showed a negative correlation with the sciatic nerve’s FA (r = –0.52, P < 0.001), with a closer correlation in DN patients (r = –0.66, P < 0.001). hsTNT further correlated positively with the neuropathy disability score (r = 0.39, P = 0.005). Negative correlations were found with sural nerve conduction velocities (NCVs) (r = –0.65, P < 0.001) and tibial NCVs (r = –0.44, P = 0.002) and amplitudes (r = –0.53, P < 0.001). This study is the first to show that hsTNT is a potential indicator for structural nerve damage in T2D. Our results indirectly support the hypothesis that microangiopathy contributes to structural nerve damage in T2D. Full Article

cr PET Imaging of Pancreatic Dopamine D2 and D3 Receptor Density with 11C-(+)-PHNO in Type 1 Diabetes By jnm.snmjournals.org Published On :: 2020-04-01T06:00:28-07:00 Type 1 diabetes mellitus (T1DM) has traditionally been characterized by a complete destruction of β-cell mass (BCM); however, there is growing evidence of possible residual BCM present in T1DM. Given the absence of in vivo tools to measure BCM, routine clinical measures of β-cell function (e.g., C-peptide release) may not reflect BCM. We previously demonstrated the potential utility of PET imaging with the dopamine D2 and D3 receptor agonist 3,4,4a,5,6,10b-hexahydro-2H-naphtho[1,2-b][1,4]oxazin-9-ol (11C-(+)-PHNO) to differentiate between healthy control (HC) and T1DM individuals. Methods: Sixteen individuals participated (10 men, 6 women; 9 HCs, 7 T1DMs). The average duration of diabetes was 18 ± 6 y (range, 14–30 y). Individuals underwent PET/CT scanning with a 120-min dynamic PET scan centered on the pancreas. One- and 2-tissue-compartment models were used to estimate pancreas and spleen distribution volume. Reference region approaches (spleen as reference) were also investigated. Quantitative PET measures were correlated with clinical outcome measures. Immunohistochemistry was performed to examine colocalization of dopamine receptors with endocrine hormones in HC and T1DM pancreatic tissue. Results: C-peptide release was not detectable in any T1DM individuals, whereas proinsulin was detectable in 3 of 5 T1DM individuals. Pancreas SUV ratio minus 1 (SUVR-1) (20–30 min; spleen as reference region) demonstrated a statistically significant reduction (–36.2%) in radioligand binding (HCs, 5.6; T1DMs, 3.6; P = 0.03). Age at diagnosis correlated significantly with pancreas SUVR-1 (20–30 min) (R2 = 0.67, P = 0.025). Duration of diabetes did not significantly correlate with pancreas SUVR-1 (20–30 min) (R2 = 0.36, P = 0.16). Mean acute C-peptide response to arginine at maximal glycemic potentiation did not significantly correlate with SUVR-1 (20–30 min) (R2 = 0.57, P = 0.05), nor did mean baseline proinsulin (R2 = 0.45, P = 0.10). Immunohistochemistry demonstrated colocalization of dopamine D3 receptor and dopamine D2 receptor in HCs. No colocalization of the dopamine D3 receptor or dopamine D2 receptor was seen with somatostatin, glucagon, or polypeptide Y. In a separate T1DM individual, no immunostaining was seen with dopamine D3 receptor, dopamine D2 receptor, or insulin antibodies, suggesting that loss of endocrine dopamine D3 receptor and dopamine D2 receptor expression accompanies loss of β-cell functional insulin secretory capacity. Conclusion: Thirty-minute scan durations and SUVR-1 provide quantitative outcome measures for 11C-(+)-PHNO, a dopamine D3 receptor–preferring agonist PET radioligand, to differentiate BCM in T1DM and HCs.

cr Theranostics Targeting Fibroblast Activation Protein in the Tumor Stroma: 64Cu- and 225Ac-Labeled FAPI-04 in Pancreatic Cancer Xenograft Mouse Models By jnm.snmjournals.org Published On :: 2020-04-01T06:00:28-07:00 Fibroblast activation protein (FAP), which promotes tumor growth and progression, is overexpressed in cancer-associated fibroblasts of many human epithelial cancers. Because of its low expression in normal organs, FAP is an excellent target for theranostics. In this study, we used radionuclides with relatively long half-lives, 64Cu (half-life, 12.7 h) and 225Ac (half-life, 10 d), to label FAP inhibitors (FAPIs) in mice with human pancreatic cancer xenografts. Methods: Male nude mice (body weight, 22.5 ± 1.2 g) were subcutaneously injected with human pancreatic cancer cells (PANC-1, n = 12; MIA PaCa-2, n = 8). Tumor xenograft mice were investigated after the intravenous injection of 64Cu-FAPI-04 (7.21 ± 0.46 MBq) by dynamic and delayed PET scans (2.5 h after injection). Static scans 1 h after the injection of 68Ga-FAPI-04 (3.6 ± 1.4 MBq) were also acquired for comparisons using the same cohort of mice (n = 8). Immunohistochemical staining was performed to confirm FAP expression in tumor xenografts using an FAP-α-antibody. For radioligand therapy, 225Ac-FAPI-04 (34 kBq) was injected into PANC-1 xenograft mice (n = 6). Tumor size was monitored and compared with that of control mice (n = 6). Results: Dynamic imaging of 64Cu-FAPI-04 showed rapid clearance through the kidneys and slow washout from tumors. Delayed PET imaging of 64Cu-FAPI-04 showed mild uptake in tumors and relatively high uptake in the liver and intestine. Accumulation levels in the tumor or normal organs were significantly higher for 64Cu-FAPI-04 than for 68Ga-FAPI-04, except in the heart, and excretion in the urine was higher for 68Ga-FAPI-04 than for 64Cu-FAPI-04. Immunohistochemical staining revealed abundant FAP expression in the stroma of xenografts. 225Ac-FAPI-04 injection showed significant tumor growth suppression in the PANC-1 xenograft mice, compared with the control mice, without a significant change in body weight. Conclusion: This proof-of-concept study showed that 64Cu-FAPI-04 and 225Ac-FAPI-04 could be used in theranostics for the treatment of FAP-expressing pancreatic cancer. α-therapy targeting FAP in the cancer stroma is effective and will contribute to the development of a new treatment strategy.

cr Comparison of 3 Interpretation Criteria for 68Ga-PSMA11 PET Based on Inter- and Intrareader Agreement By jnm.snmjournals.org Published On :: 2020-04-01T06:00:28-07:00 PET using radiolabeled prostate-specific membrane antigen (PSMA) is now being more widely adopted as a valuable tool to evaluate patients with prostate cancer (PC). Recently, 3 different criteria for interpretation of PSMA PET were published: the European Association of Nuclear Medicine (EANM) criteria, the Prostate Cancer Molecular Imaging Standardized Evaluation criteria, and the PSMA Reporting and Data System. We compared these 3 criteria in terms of interreader, intrareader, and intercriteria agreement. Methods: Data from 104 patients prospectively enrolled in research protocols at our institution were retrospectively reviewed. The cohort consisted of 2 groups: 47 patients (mean age, 64.2 y old) who underwent Glu-NH-CO-NH-Lys-(Ahx)-[68Ga(HBED-CC)] (68Ga-PSMA11) PET/MRI for initial staging of biopsy-proven intermediate- or high-risk PC, and 57 patients (mean age, 70.5 y old) who underwent 68Ga-PSMA11 PET/CT because of biochemically recurrent PC. Three nuclear medicine physicians independently evaluated all 68Ga-PSMA11 PET/MRI and PET/CT studies according to the 3 interpretation criteria. Two of them reevaluated all studies 6 mo later in the same manner and masked to the initial reading. The Gwet agreement coefficient was calculated to evaluate interreader, intrareader, and intercriteria agreement based on the following sites: local lesion (primary tumor or prostate bed after radical prostatectomy), lymph node metastases, and other metastases. Results: In the PET/MRI group, interreader, intrareader, and intercriteria agreement ranged from substantial to almost perfect for any site according to all 3 criteria. In the PET/CT group, interreader agreement ranged from substantial to almost perfect except for judgment of distant metastases based on the PSMA Reporting and Data System (Gwet agreement coefficient, 0.57; moderate agreement), in which the most frequent cause of disagreement was lung nodules. Intrareader agreement ranged from substantial to almost perfect for any site according to all 3 criteria. Intercriteria agreement for each site was also substantial to almost perfect. Conclusion: Although the 3 published criteria have good interreader and intrareader reproducibility in evaluating 68Ga-PSMA11 PET, there are some factors causing interreader disagreement. Further work is needed to address this issue. Full Article
cr Evidence of Tissue Repair in Human Donor Pancreas After Prolonged Duration of Stay in Intensive Care By diabetes.diabetesjournals.org Published On :: 2020-02-20T11:55:30-08:00 M2 macrophages play an important role in tissue repair and regeneration. They have also been found to modulate β-cell replication in mouse models of pancreatic injury and disease. We previously reported that β-cell replication is strongly increased in a subgroup of human organ donors characterized by prolonged duration of stay in an intensive care unit (ICU) and increased number of leukocytes in the pancreatic tissue. In the present study we investigated the relationship between duration of stay in the ICU, M2 macrophages, vascularization, and pancreatic cell replication. Pancreatic organs from 50 donors without diabetes with different durations of stay in the ICU were analyzed by immunostaining and digital image analysis. The number of CD68+CD206+ M2 macrophages increased three- to sixfold from ≥6 days’ duration of stay in the ICU onwards. This was accompanied by a threefold increased vascular density and a four- to ninefold increase in pancreatic cells positive for the replication marker Ki67. A strong correlation was observed between the number of M2 macrophages and β-cell replication. These results show that a prolonged duration of stay in the ICU is associated with an increased M2 macrophage number, increased vascular density, and an overall increase in replication of all pancreatic cell types. Our data show evidence of marked levels of tissue repair in the human donor pancreas. Full Article
cr A Critical Insulin TCR Contact Residue Selects High-Affinity and Pathogenic Insulin-Specific T Cells By diabetes.diabetesjournals.org Published On :: 2020-02-20T11:55:30-08:00 Type 1 diabetes is an autoimmune-mediated disease that culminates in the targeted destruction of insulin-producing β-cells. CD4 responses in NOD mice are dominated by insulin epitope B:9-23 (InsB9-23) specificity, and mutation of the key T-cell receptor (TCR) contact residue within the epitope prevents diabetes development. However, it is not clear how insulin self-antigen controls the selection of autoimmune and regulatory T cells (Tregs). Here we demonstrate that mutation of insulin epitope results in escape of highly pathogenic T cells. We observe an increase in antigen reactivity, clonality, and pathogenicity of insulin-specific T cells that develop in the absence of cognate antigen. Using a single TCR system, we demonstrate that Treg development is greatly diminished in mice with the Y16A mutant epitope. Collectively, these results suggest that the tyrosine residue at position 16 is necessary to constrain TCR reactivity for InsB9-23 by both limiting the development of pathogenic T cells and supporting the selection of Tregs.

cr {beta}-Cell Stress Shapes CTL Immune Recognition of Preproinsulin Signal Peptide by Posttranscriptional Regulation of Endoplasmic Reticulum Aminopeptidase 1 By diabetes.diabetesjournals.org Published On :: 2020-03-20T11:50:28-07:00 The signal peptide of preproinsulin is a major source for HLA class I autoantigen epitopes implicated in CD8 T cell (CTL)–mediated β-cell destruction in type 1 diabetes (T1D). Among them, the 10-mer epitope located at the C-terminal end of the signal peptide was found to be the most prevalent in patients with recent-onset T1D. While the combined action of signal peptide peptidase and endoplasmic reticulum (ER) aminopeptidase 1 (ERAP1) is required for processing of the signal peptide, the mechanisms controlling signal peptide trimming and the contribution of the T1D inflammatory milieu on these mechanisms are unknown. Here, we show in human β-cells that ER stress regulates ERAP1 gene expression at posttranscriptional level via the IRE1α/miR-17-5p axis and demonstrate that inhibition of the IRE1α activity impairs processing of preproinsulin signal peptide antigen and its recognition by specific autoreactive CTLs during inflammation. These results underscore the impact of ER stress in the increased visibility of β-cells to the immune system and position the IRE1α/miR-17 pathway as a central component in β-cell destruction processes and as a potential target for the treatment of autoimmune T1D.

cr The Future of Democracy in Europe: Technology and the Evolution of Representation By feedproxy.google.com Published On :: Tue, 25 Feb 2020 11:31:48 +0000 3 March 2020 To the extent that perceptions of a crisis in liberal democracy in Europe can be confirmed, this paper investigates the nature of the problem and its causes, and asks what part, if any, digital technology plays in it.

SummaryThere is a widespread sense that liberal democracy is in crisis, but little consensus exists on the specific nature and causes of the crisis. In particular, there are three prisms through which the crisis is usually seen: the rise of ‘populism’, ‘democratic deconsolidation’, and a ‘hollowing out’ of democracy. Each reflects normative assumptions about democracy.The exact role of digital technology in the crisis is disputed. Despite the widely held perception that social media is undermining democracy, the evidence for this is limited. Over the longer term, the further development of digital technology could undermine the fundamental preconditions for democracy – though the pace and breadth of technological change make predictions about its future impact difficult.Democracy functions in different ways in different European countries, with political systems on the continent ranging from ‘majoritarian democracies’ such as the UK to ‘consensual democracies’ such as Belgium and Switzerland. However, no type seems to be immune from the crisis. The political systems of EU member states also interact in diverse ways with the EU’s own structure, which is problematic for representative democracy as conventionally understood, but difficult to reform.Political parties, central to the model of representative democracy that emerged in the late 18th century, have long seemed to be in decline. Recently there have been some signs of a reversal of this trend, with the emergence of parties that have used digital technology in innovative ways to reconnect with citizens. Traditional parties can learn from these new ‘digital parties’.Recent years have also seen a proliferation of experiments in direct and deliberative democracy. There is a need for more experimentation in these alternative forms of democracy, and for further evaluation of how they can be integrated into the existing institutions and processes of representative democracy at the local, regional, national and EU levels.We should not think of democracy in a static way – that is, as a system that can be perfected once and for all and then simply maintained and defended against threats. Democracy has continually evolved and now needs to evolve further. The solution to the crisis will not be to attempt to limit democracy in response to pressure from ‘populism’ but to deepen it further as part of a ‘democratization of democracy’.

While some attribute this crisis to the rise of populist figures, movements and parties, others see populism as a response to a deeper hollowing out of democracy during the last several decades. Some blame the development of digital technology – in particular the emergence of social media – while others argue that the correlation between the development of digital technology and the perceived corrosion of democracy is exaggerated or that it has facilitated greater participation in politics from traditionally under-represented demographics in a way that was not previously possible.Launching the Chatham House research paper The Future of Democracy in Europe, this panel will discuss how liberal democracy is evolving against the background of social and technological change. What are the challenges to liberal democracy in Europe? How should we understand the impact of technology on how democracy in Europe functions? Given the plurality of democratic structures and institutions across the continent, how can democracy in Europe be reinvigorated? And what role can citizens' assemblies and referendums play in making democracy more responsive to citizens?This event is open to Chatham House Members only. Not a member?

cr Coronavirus and the Future of Democracy in Europe By feedproxy.google.com Published On :: Tue, 31 Mar 2020 14:46:26 +0000 31 March 2020 Hans Kundnani Senior Research Fellow, Europe Programme @hanskundnani The pandemic raises difficult questions about whether liberal democracies can adequately protect their citizens. 2020-03-31-Police-Poland Police officers wearing protective face masks patrol during coronavirus lockdown enforcement in Wroclaw, Poland. Photo by Bartek Sadowski/Bloomberg via Getty Images. It is less than a month since we published our research paper on the future of democracy in Europe. But it feels like we now live in a different world. The coronavirus has already killed thousands of people in Europe, led to an unprecedented economic crisis and transformed daily life – and in the process raised difficult new questions about democracy.The essence of our argument in the paper was that democracy in Europe should be deepened. But now there is a much more basic question about whether democracies can protect their citizens from the pandemic.There has already been much discussion about whether authoritarian states will emerge stronger from this crisis than democracies. In particular, although the virus originated in China and the government initially seemed to struggle to deal with it, it was able to largely contain the outbreak in Hubei and deploy vast resources from the rest of the country to deal with it.Come through the worstChina may have come through the worst of the health crisis – though a second wave of infections as restrictions are lifted is possible – and there have already been three times as many deaths in Italy, and twice as many in Spain, as in China (although there is increasing doubt about the accuracy of China’s figures).However, it is not only authoritarian states that seem so far to have coped relatively well with the virus. In fact, some East Asian democracies appear to have done even better than China. At the time of writing South Korea, with a population of 51.5 million, has had only 144 death rates so far. Taiwan, with a population of nearly 24 million, has had only two deaths.So rather than thinking in terms of the relative performance of authoritarian states and democracies, perhaps instead we should be asking what we in Europe can learn from East Asian democracies.It is not yet clear why East Asian democracies were able to respond so effectively, especially as they did not all follow exactly the same approach. Whereas some quickly imposed restrictions on travel (for example, Taiwan suspended flights from China and then prohibited the entry of people from China and other affected countries) and quarantines, others used extensive testing and contact tracing, often making use of personal data collected from citizens.Whatever the exact strategy they used, though, they did all act quickly and decisively – and the collective memory of the SARS outbreak in 2003 and other recent epidemics seems to have played a role in this. For example, following the SARS outbreak, Taiwan created a central epidemic command center. Europe, meanwhile, was hardly affected by SARS – and we seem to have assumed the coronavirus would be the same (although that does not quite explain why we were still so slow to react in February even after it was clear that the virus had spread to Italy).However, while the relative success of East Asian democracies may have something to do with this recent experience of epidemics, it may also have something to do with the kind of democracies they are. It may be a simple matter of competence – the bureaucracy in Taiwan and South Korea may function better, and in particular in a more coordinated way, than in many European countries.But it may also be more than that. In particular, it could be that East Asian democracies have a kind of 'authoritarian residue' that has helped in the initial response to this crisis. South Korea and Taiwan are certainly vibrant democracies – but they are also relatively new democracies compared to many in Europe. As a result, citizens may have a different relationship with the state and be more willing to accept sudden restrictions of freedoms, in particular on movement, and the use of personal data – at least in a crisis.In that sense, the pandemic may be a challenge not to democracy as such but to liberal democracy in particular – in other words, a system of popular sovereignty together with guaranteed basic rights, such as including freedom of association and expression and checks and balances on executive power. There may now be difficult trade-offs to be made between those basic rights and security – and, after the experience of coronavirus, many citizens may choose security.This brings us back to the issues we discussed in our research paper. Even before the coronavirus hit, there was already much discussion of a crisis of liberal democracy. In particular, there has been a debate about whether liberalism and democracy, which had long been assumed to go together, were becoming decoupled.In particular, ‘illiberal democracies’ seemed to be emerging in many places including Europe (although, as we discuss in the paper, some analysts argue that the term is incoherent). This model of ‘illiberal democracy’ – in other words, one in which elections continue to be held but some individual rights are curtailed – may emerge stronger from this new crisis.It is striking that Singapore – also seen as responding successfully to coronavirus – was seen as a paradigmatic ‘illiberal democracy’ long before Hungarian Prime Minister Viktor Orbán embraced the idea. In particular, there is little real opposition to the People’s Action Party, which has been in power since 1959.Since this new crisis began, Orbán has gone further in suspending rights in Hungary. On March 11, he declared a state of emergency – as many other European countries have also done. But he has now gone further by passing legislation that allows him to govern by decree indefinitely and make it illegal to spread misinformation that undermines the government’s response to the pandemic. Clearly, this is a further decisive step in the deconsolidation of liberal democracy in Hungary.So far, though, much of the discussion, particularly in the foreign policy world, has focused mainly on how to change popular perceptions that liberal democracies are failing in this crisis. For example, High Representative Josep Borrell, the European Union’s foreign minister, wrote last week of a 'battle of narratives'.But this misses the point. It is not a matter of spinning the European model, but of taking seriously the substantial questions raised by the coronavirus about the ability of liberal democracies to adequately protect their citizens.

As Europe contends with a perceived crisis of democracy - now compounded by the varied responses to the coronavirus outbreak - how should we understand the relationship between externally-driven economic crises, political upheaval and democracy?The panellists will consider the parallels between the political responses to some of the greatest economic crises Europe has experienced in the last century. Given that economic crises often transcend borders, why does political disruption vary between democracies? What can history tell us about the potential political impact of the unfolding COVID-19-related economic crisis? And will the unprecedented financial interventions by governments across Europe fundamentally change the expectations citizens have of the role government should play in their lives?This event is based on a recent article in The World Today by Hans Kundnani and Pepijn Bergsen who are both researchers in Chatham House's Europe Programme. 'Crawling from the Wreckage' is the first in a series of articles that look at key themes in European political discourse from the last century. You can read the article here.

cr Joining Up the Dots: Energy and Infrastructure for Countries in Crisis By feedproxy.google.com Published On :: Mon, 16 Dec 2019 12:53:31 +0000 16 December 2019 Glada Lahn Senior Research Fellow, Energy, Environment and Resources Programme @Glada_Lahn Suzanna Huber Hajar Al-Kaddo Could a refugee crisis help the host-country improve its health and development outcomes? The ‘energy and infrastructure’ focus at this week’s first UN Global Refugee Forum suggests it could, where national policy enables it. Practical action RV0_1139.jpg A man serves customers at a shop in Nyahbiheke Refugee Camp, Rwanda. Energy access makes it possible for refugees to power and run businesses. Photo: Practical Action. Mass human displacement crises like those in Syria, Democratic Republic of Congo and Myanmar do not dissipate within a year or two. The average age of a refugee camp globally is 18 and counting.Meanwhile, the pressures on resources and services in neighbouring countries absorbing an influx of vulnerable people can be harsh. Imagine the overstressed schools and hospitals where intake has doubled in areas of Jordan and Lebanon, and the damage to ecosystems and elephant habitats where camps have sprung up in Bangladesh. The fallout from such crises is prompting new ways of working in the international humanitarian system. These recognize that short-term, emergency responses can jeopardize national development goals if maintained indefinitely. In most refugee camps for instance, each family cooks with wood in regions already suffering from deforestation.Reliance on polluting trucks to bring in fuel and water is high. At the same time, developing countries – which host 80 per cent of the record 70.8 million people currently displaced by conflict – desperately need to address health, water, energy and housing needs for their own populations. Aid and welfare interventions directed only at refugees can provoke frustrations amongst the local community, damaging social cohesion and fostering political instability. The Global Compact on Refugees, affirmed by the United Nations General Assembly one year ago, aims at fairer responsibility-sharing amongst countries and equitable resourcing to host communities and refugees. The Global Refugee Forum (GRF) taking place 17–18 December in Geneva is the starting point for donor pledges and commitments. An opportunity for refugee-hosting countriesAmong the GRF’s 6 focus themes is ‘Energy and Infrastructure’ – a new priority for humanitarian aid and finance. This covers energy, environment, water and sanitation, health, shelter and connectivity – services that are tightly interconnected. In October, the UN Refugee Agency (UNHCR) also launched its first energy strategy, which ‘promotes the transition to clean, renewable energy at refugee camps and hosting sites’.Given this impetus, alongside a growing international focus on speeding up Sustainable Development Goal (SDG) delivery, stabilizing migration and supporting climate resilience, more aid and soft credit for interlinked objectives will become available. Countries hosting refugees have an opportunity; how they approach it will determine the level of support they attract and how effectively it is deployed. Policy conditions are key to successIn a refugee situation, energy access is about much more than keeping warm or cooking food. It is also about connecting with loved ones across borders, safety at night, healthy births and making a living. Due to the lack of long-term funding, maintenance systems or government approvals, failed pilots to introduce for example, solar streetlighting or clean cookstoves, are the norm. To increase their durability and reach, projects need to harness local markets and support national development goals, especially those on access to modern energy for all (SDG 7), protecting ecosystems (SDG 15) and resilient human settlements (SDG 11). Several examples of these are emerging, each with valuable lessons to share. The policy environment, in particular, coordination between authorities, humanitarian agencies and private sector actors, can make or break a project. Beyond the basic conditions of adequate security and refugee acceptance, our research highlights three enabling factors:First: government willingness to engage in long-term response and resilience coordination. Jordan is the most advanced in this with its three-year rolling Response Plan for the Syria Crisis whereby the government works with humanitarian agencies to integrate refugee welfare with national development needs.Here, energy, water and housing needs are specified and have attracted funding. For example, in Irbid, Jordan where over 137,600 Syrian refugees live, the Norwegian Refugee Council, is expanding a programme under the Renewable Energy for Refugees (RE4R) initiative that applies energy efficiency and solar water heating to reduce bills and rents for refugee tenants while adding value for Jordanian homeowners. Second: strong, clear, energy and environment plans and legislation. Signals can be mixed. Jordan’s ‘wheeling’ regulation, allowed UNHCR to reduce its electricity bills through specially built solar plants at Azraq and Zaatari, yet the current freeze on renewable connections has stifled further projects.In Rwanda, the government banned the supply of woodfuel to refugee camps on the basis of concerns about deforestation. The announcement sharpens focus on cleaner cooking.Yet with little guidance on enforcement and the timeframe for change, it is difficult for UNHCR and its partners to plan viable schemes. A reversion to stove and fuel handouts is likely, damaging the potential to create markets for alternative cooking practices in the camps. Third: local fuel prices. Where polluting fuels are subsidized or untaxed, additional subsidy is needed to make cleaner alternatives competitive. The higher prices of diesel in Uganda for example are an incentive for solar projects at Bidi Bidi, the world’s largest refugee settlement.The Gaia Association-UNHCR clean energy programme in Ethiopia’s Western refugee camps has avoided burning some 10,000 tonnes of wood since 2006 through ethanol, but if VAT (which is applied to neither charcoal nor kerosene) were waived, it could scale up commercially. Joining up the dotsMany humanitarian and government dots could be joined up in support of the SDGs. In Rwanda for example, clarity on electrification plans – which appear to cover refugee areas – could allow camp mini-grids to be designed for eventual grid integration. In Jordan, lessons learned from the home upgrading programme could be applied to meet city climate resilience ambitions. Donors at the GRF should support humanitarian operations that leave a positive legacy, increasing the robustness of country infrastructure and systems. Host-country governments should help define and encourage projects that benefit national and refugee populations. This will be critical to both development outcomes and limiting future human suffering. Full Article
cr Iran Crisis: The Impact on Oil Markets By feedproxy.google.com Published On :: Tue, 14 Jan 2020 09:00:23 +0000 14 January 2020 Professor Paul Stevens Distinguished Fellow, Energy, Environment and Resources Programme The assassination of Qassem Soleimani has exacerbated the sensitivity of oil markets to political events and brought geopolitics back into global oil prices. 2020-01-14-Hormuz.jpg Satellite image of the Strait of Hormuz. Photo: Getty Images. The assassination of General Qassem Soleimani has created much speculation about the possible impact on oil markets and – although any impact will very much depend upon what happens next in terms of political and military responses – theoretically the potential exists for Iran to seriously destabilize oil markets, raising oil prices.Arguably, it would be in Iran’s interest to do so. It would certainly hurt Trump’s possibility of a second term if higher prices were to last for some time as the 2020 presidential election gets underway. And it would also help shore up Iran’s failing economy. The assassination did initially cause oil prices to rise by a few dollars before quickly falling back, and the missile attacks by Iran produced a similar response. However, direct action by Iran to raise prices – for example by trying to close the Strait of Hormuz – is unlikely.Around one-fifth of the world's oil supplies passes through the Strait of Hormuz, a narrow choke point between Iran and the Arabian Peninsula. Closing it would invite serious military action by the Americans and many of its allies who, so far, have been rather lukewarm over Trump’s actions. It would also possibly limit Iran’s own oil exports.Similarly, overt attacks on American allies in the region such as Saudi Arabia and the UAE would probably invite too heavy a reaction, although this is uncertain given the lack of response after the alleged Iranian attacks on Abqaiq and Khurais in mid-September.Indirect action by Iran to affect oil supplies is much more likely as they have many options by using their proxies to affect others’ oil production. This is especially true for Iraq, which is now an important source of global oil supply as Iraqi exports in 2019 averaged 3.53 million barrels per day (Mb/d), a significant amount.Iraq’s future production has already been damaged as international oil companies are withdrawing staff for safety reasons, anticipating potential attacks by both Iraqi and Iranian sources. It is now very unlikely that the crucial ‘common seawater supply project’ being run by Exxon – essential for expanding production capacity – will go ahead in the near future.However, one important consequence of the assassination that has attracted little attention is that it has almost fully restored the role of geopolitics into the determination of oil prices. Up to 2014, geopolitics played a key role in determining oil prices in the paper markets where perceptions and expectations ruled.Prices determined in these markets – NYMEX in New York, ICE in London and other lesser futures markets throughout the world – then influence wet barrel markets where real barrels of oil are traded. In 2014, the world was so oversupplied with real oil barrels that the oil price collapsed – the price of Brent crude fell from $110.72 on 23 May to $46.44 eight months later. Thereafter, little if any attention was given to geopolitical events, and geopolitics became marginalized in the determination of crude oil prices.This began to change in 2019. The market remained physically over-supplied but events in the Gulf began to attract attention. In June, there were a series of attacks on oil tankers close to the Gulf, followed by attacks on Saudi Arabia’s Abqaiq processing facility and the Khurais oil field in September.The Americans claimed these attacks were launched by Iran, but no convincing evidence for the claim was provided. Both attacks produced an initial price response but it was surprisingly limited and short-lived. However, it did suggest that geopolitics might be creeping back into influencing oil prices.This became ever more noticeable in the third and fourth quarters as rumours regarding the trade talks between China and US clearly began to affect price – talks going well meant higher oil demand, and prices rose; talks going badly meant lower oil demand, and prices fell.Meanwhile, the oil market showed signs of tightening towards the end of 2019. Although there was much cheating on the OPEC+ agreement that was trying to restrain production and protect prices, the OPEC meeting last December saw both Iraq and Nigeria agreeing to restrain production. US stock levels also began to fall in December and the futures markets began to price in a tightening market towards the end of 2020. Significantly, the tighter the market appears, the greater attention is paid to the level of spare producing capacity.Just before the attack on Abqaiq, the International Energy Agency (IEA) estimated there was 3.5 Mb/d spare capacity in OPEC which, historically, is quite comfortable. However, 2.5 of this was estimated to be in Saudi Arabia, so how much of this spare capacity still existed after the Abqaiq attack?The Saudis claimed the Abqaiq capacity was quickly restored but technical experts greeted this with considerable skepticism, not least because the Abqaiq equipment was highly specialized. If spare capacity is tight, this makes the oil price vulnerable to geopolitical scares and rumours, real or imagined. Although the assassination of General Soleimani has exacerbated the sensitivity of oil markets to geopolitical events, this becomes irrelevant if a serious shooting war starts in the region. Saudi Arabia, the UAE and Iraq’s oil infrastructure remains highly vulnerable to attack either directly by Iran or one of its many proxies, suggesting oil prices will become increasingly volatile but, at the same time, benefit from a rising geopolitical premium.

cr Why an Inclusive Circular Economy is Needed to Prepare for Future Global Crises By feedproxy.google.com Published On :: Wed, 15 Apr 2020 13:23:01 +0000 15 April 2020 Patrick Schröder Senior Research Fellow, Energy, Environment and Resources Programme @patricks_CH Google Scholar The risks associated with existing production and consumption systems have been harshly exposed amid the current global health crisis but an inclusive circular economy could ensure both short-term and long-term resilience for future challenges. 2020-04-15-Waste-Collection-Peru.jpg Lima city employees picking up garbage during lockdown measures in Peru amid the COVID-19 crisis. Photo: Getty Images. The world is currently witnessing how vulnerable existing production and consumption systems are, with the current global health crisis harshly exposing the magnitude of the risks associated with the global economy in its current form, grounded, as it is, in a linear system that uses a ‘take–make–throw away’ approach.These ‘linear risks’ associated with the existing global supply chain system are extremely high for national economies overly dependent on natural resource extraction and exports of commodities like minerals and metals. Equally vulnerable are countries with large manufacturing sectors of ready-made garments and non-repairable consumer goods for western markets. Furthermore, workers and communities working in these sectors are vulnerable to these changes as a result of disruptive technologies and reduced demand.In a recently published Chatham House research paper, ‘Promoting a Just Transition to an Inclusive Circular Economy’, we highlight why a circular economy approach presents the world with a solution to old and new global risks – from marine plastic pollution to climate change and resource scarcity.Taking the long viewSo far, action to transition to a circular economy has been slow compared to the current crisis which has mobilized rapid global action. For proponents of transitioning to a circular economy, this requires taking the long view. The pandemic has shown us that global emergencies can fast-forward processes that otherwise might take years, even decades, to play out or reverse achievements which have taken years to accomplish.In this vein, there are three striking points of convergence between the COVID-19 pandemic and the need to transition to an inclusive circular economy.Firstly, the current crisis is a stark reminder that the circular economy is not only necessary to ensure long-term resource security but also short-term supplies of important materials. In many cities across the US, the UK and Europe, councils have suspended recycling to focus on essential waste collection services. The UK Recycling Association, for example, has warned about carboard shortages due to disrupted recycling operations with possible shortages for food and medicine packaging on the horizon.Similarly, in China, most recycling sites were shut during the country’s lockdown presenting implications for global recycling markets with additional concerns that there will be a fibre shortage across Europe and possibly around the world.Furthermore, worldwide COVID-19 lockdowns are resulting in a resurgence in the use of single-use packaging creating a new wave of plastic waste especially from food deliveries – already seen in China – with illegal waste fly-tipping dramatically increasing in the UK since the lockdown.In this vein, concerns over the current global health crisis is reversing previous positive trends where many cities had established recycling schemes and companies and consumers had switched to reusable alternatives.Secondly, the need to improve the working conditions of the people working in the informal circular economy, such as waste pickers and recyclers, is imperative. Many waste materials and recyclables that are being handled and collected may be contaminated as a result of being mixed with medical waste.Now, more than ever, key workers in waste management, collection and recycling require personal protective equipment and social protection to ensure their safety as well as the continuation of essential waste collection so as not to increase the potential for new risks associated with additional infectious diseases.In India, almost 450 million workers including construction workers, street vendors and landless agricultural labourers, work in the informal sector. In the current climate, the poorest who are unable to work pose a great risk to the Indian economy which could find itself having to shut down.Moreover, many informal workers live in make-shift settlements areas such as Asia’s largest slum, Dharavi in Mumbai, where health authorities are now facing serious challenges to contain the spread of the disease. Lack of access to handwashing and sanitation facilities, however, further increase these risks but circular, decentralized solutions could make important contributions to sustainable sanitation, health and improved community resilience.Thirdly, it is anticipated that in the long term several global supply chains will be radically changed as a result of transformed demand patterns and the increase in circular practices such as urban mining for the recovery and recycling of metals or the reuse and recycling of textile fibres and localized additive manufacturing (e.g. 3D printing).Many of these supply chains and trade flows have now been already severely disrupted due to the COVID-19 pandemic. For example, the global garment industry has been particularly hard-hit due to the closure of outlets amid falling demand for apparel.It is important to note, workers at the bottom of these garment supply chains are among the most vulnerable and most affected by the crisis as global fashion brands, for example, have been cancelling orders – in the order of $6 billion in the case of Bangladesh alone. Only after intense negotiations are some brands assuming financial responsibility in the form of compensation wage funds to help suppliers in Myanmar, Cambodia and Bangladesh to pay workers during the ongoing crisis.In addition, the current pandemic is damaging demand for raw materials thereby affecting mining countries. Demand for Africa’s commodities in China, for example, has declined significantly, with the impact on African economies expected to be serious, with 15 per cent of the world’s copper and 20 per cent of the world’s zinc mines currently going offline. A further threat is expected to come from falling commodity prices as a result of the curtailment of manufacturing activity in China particularly for crude oil, copper, iron ore and other industrial commodities which, in these cases, will have direct impacts on the Australian and Canadian mining sectors.This is all being compounded by an associated decline in consumer demand worldwide. For example, many South African mining companies – leading producers of metals and minerals – have started closing their mining operations following the government’s announcement of a lockdown in order to prevent the transmission of the virus among miners who often work in confined spaces and in close proximity with one another. As workers are laid off due to COVID-19, there are indications that the mining industry will see fast-tracking towards automated mining operations. All of these linear risks that have been exposed through the COVID-19 pandemic reinforce the need for a just transition to a circular economy. But while the reduction in the consumption of resources is necessary to achieve sustainability, the social impacts on low- and middle- income countries and their workers requires international support mechanisms.In addition, the current situation also highlights the need to find a new approach to globalized retail chains and a balance between local and global trade based on international cooperation across global value chains rather than implementation of trade protectionist measures.In this vein, all of the recovery plans from the global COVID-19 pandemic need to be aligned with the principles of an inclusive circular economy in order to ensure both short-term and long-term resilience and preparedness for future challenges and disruptions.

cr Same Old Politics Will Not Solve Iraq Water Crisis By feedproxy.google.com Published On :: Wed, 15 Apr 2020 15:36:21 +0000 15 April 2020 Georgia Cooke Project Manager, Middle East and North Africa Programme Dr Renad Mansour Senior Research Fellow, Middle East and North Africa Programme; Project Director, Iraq Initiative @renadmansour Glada Lahn Senior Research Fellow, Energy, Environment and Resources Programme @Glada_Lahn Addressing Iraq’s water crisis should be a priority for any incoming prime minister as it is damaging the country’s attempts to rebuild. But successive governments have allowed the problem to fester. 2020-04-15-Iraq-Water Punting in the marshes south of the Iraqi city of Ammarah. Photo by Ghaith Abdul-Ahad/Getty Images. Historically, Iraq lay claim to one of the most abundant water supplies in the Middle East. But the flow of the Tigris and Euphrates rivers has reduced by up to 40% since the 1970s, due in part to the actions of neighbouring countries, in particular Turkey, upstream.Rising temperatures and reduced rainfall due to climate change are also negatively impacting Iraq’s water reserves. Evaporation from dams and reservoirs is estimated to lose the country up to 8 billion cubic metres of water every year.A threat to peace and stabilityShortages have dried up previously fertile land, increasing poverty in agricultural areas. Shortages have also served to fuel conflict: communities faced with successive droughts and government inertia proved to be easy targets for ISIS recruiters, who lured farmers into joining them by offering money and food to feed their families. Economic hardship for those whose livelihoods relied upon river water has also driven rural to urban migration, putting significant strain on already over-populated towns and cities, exacerbating housing, job and electricity shortages, and widening the gap between haves and have-nots.But scarcity isn’t the most crucial element of Iraq’s water crisis – contamination is. Decades of local government mismanagement, corrupt practices and a lack of regulation of dumping (it is estimated up to 70% of Iraq’s industrial waste is dumped directly into water) has left approximately three in every five citizens without a reliable source of potable water.In 2018, 118,000 residents of Basra province were hospitalised with symptoms brought on by drinking contaminated water, which not only put a spotlight on the inadequacies of a crumbling healthcare system but sparked mass protests and a subsequent violent crackdown.The water crisis is also undermining the stability of the country’s federal governance model, by occasionally sparking disputes between Baghdad and the Kurdistan Regional Government, as well as between governorates in the south.The crisis is both a symptom and a cause of poor governance. Iraq is stuck in a cycle whereby government inaction causes shortages and contamination, which result in economic losses, reduced food supply, increased prices and widespread poor health. This in turn leads to increasing levels of poverty, higher demand on services and civil unrest, increasing the pressure on a weak, dysfunctional system of government.What can be done?The first priority should be modernising existing water-management infrastructure - a relic of a time when the problem was an excess rather than a shortage of water (the last time Iraq’s flood defences were required was 1968). Bureaucratic hurdles, widespread corruption and an endless cycle of other crises taking precedent prevent good initiatives from being implemented or scaled up.Diversifying energy sources to improve provision is crucial. Baghdad has a sewage treatment plant that originally ran on its own electricity source, but this capacity was destroyed in 1991 and was never replaced. The city continues to suffer from dangerous levels of water pollution because the electricity supply from the grid is insufficient to power the plant. Solar energy has great potential in sun-drenched Iraq to bridge the gaping hole in energy provision, but successive governments have chosen to focus on fossil fuels rather than promoting investment to grow the renewables sector.Heightened tension with upstream Turkey could turn water into another cause of regional conflict. But, if approached differently, collaboration between Iraq and its neighbour could foster regional harmony.Turkey’s elevated geography and cooler climate mean its water reserves suffer 75% less evaporation than Iraq’s. Given that Turkey’s top energy priority is the diversification of its supply of imported hydrocarbons, a win-win deal could see Turkey exchange access to its water-management infrastructure for delivery of reduced cost energy supplies from Iraq.German-French cooperation on coal and steel in the 1950s and the evolution of economic integration that followed might provide a model for how bilateral cooperation over one issue could result in cooperation with other regional players (in this case Iran and Syria) on a range of other issues. This kind of model would need to consider the future of energy, whereby oil and gas would be replaced by solar-power exports.These solutions have been open to policymakers for years and yet they have taken little tangible action. While there are leaders and bureaucrats with the will to act, effective action is invariably blocked by a complex and opaque political system replete with vested interests in maintaining power and wealth via a weak state and limited services from central government.Breaking the cycleTo break this cycle, Iraq needs a group of professional and able actors outside of government to work with willing elements of the state bureaucracy as a taskforce to pressure for action and accountability. Publishing the recommendations from a hitherto withheld report produced in the aftermath of Basra’s 2018 heath crisis would be a great start.In time, this taskforce could champion the prioritisation of water on the national agenda, the implementation of infrastructure upgrades, and hold more productive conversations with neighbour states.With such a high degree of state fragmentation and dysfunction in Iraq, looking to the central government to provide leadership will not yield results. Engagement with a coalition of non-state actors can begin to address the water crisis and also open a dialogue around new models of governance for other critical issues. This might even be a starting point for rewriting the tattered social contract in Iraq.This piece is based on insights and discussion at a roundtable event, Conflict and the Water Crisis in Iraq, held at Chatham House on March 9 as part of the Iraq Initiative.

cr Proline-rich 11 (PRR11) drives F-actin assembly by recruiting the actin-related protein 2/3 complex in human non-small cell lung carcinoma [DNA and Chromosomes] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 The actin cytoskeleton is extremely dynamic and supports diverse cellular functions in many physiological and pathological processes, including tumorigenesis. However, the mechanisms that regulate the actin-related protein 2/3 (ARP2/3) complex and thereby promote actin polymerization and organization in cancer cells are not well-understood. We previously implicated the proline-rich 11 (PRR11) protein in lung cancer development. In this study, using immunofluorescence staining, actin polymerization assays, and siRNA-mediated gene silencing, we uncovered that cytoplasmic PRR11 is involved in F-actin polymerization and organization. We found that dysregulation of PRR11 expression results in F-actin rearrangement and nuclear instability in non-small cell lung cancer cells. Results from molecular mechanistic experiments indicated that PRR11 associates with and recruits the ARP2/3 complex, facilitates F-actin polymerization, and thereby disrupts the F-actin cytoskeleton, leading to abnormal nuclear lamina assembly and chromatin reorganization. Inhibition of the ARP2/3 complex activity abolished irregular F-actin polymerization, lamina assembly, and chromatin reorganization due to PRR11 overexpression. Notably, experiments with truncated PRR11 variants revealed that PRR11 regulates F-actin through different regions. We found that deletion of either the N or C terminus of PRR11 abrogates its effects on F-actin polymerization and nuclear instability and that deletion of amino acid residues 100–184 or 100–200 strongly induces an F-actin structure called the actin comet tail, not observed with WT PRR11. Our findings indicate that cytoplasmic PRR11 plays an essential role in regulating F-actin assembly and nuclear stability by recruiting the ARP2/3 complex in human non-small cell lung carcinoma cells.

cr CRISPR-Cas12a has widespread off-target and dsDNA-nicking effects [DNA and Chromosomes] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 Cas12a (Cpf1) is an RNA-guided endonuclease in the bacterial type V-A CRISPR-Cas anti-phage immune system that can be repurposed for genome editing. Cas12a can bind and cut dsDNA targets with high specificity in vivo, making it an ideal candidate for expanding the arsenal of enzymes used in precise genome editing. However, this reported high specificity contradicts Cas12a's natural role as an immune effector against rapidly evolving phages. Here, we employed high-throughput in vitro cleavage assays to determine and compare the native cleavage specificities and activities of three different natural Cas12a orthologs (FnCas12a, LbCas12a, and AsCas12a). Surprisingly, we observed pervasive sequence-specific nicking of randomized target libraries, with strong nicking of DNA sequences containing up to four mismatches in the Cas12a-targeted DNA-RNA hybrid sequences. We also found that these nicking and cleavage activities depend on mismatch type and position and vary with Cas12a ortholog and CRISPR RNA sequence. Our analysis further revealed robust nonspecific nicking of dsDNA when Cas12a is activated by binding to a target DNA. Together, our findings reveal that Cas12a has multiple nicking activities against dsDNA substrates and that these activities vary among different Cas12a orthologs. Full Article
cr Atomic force microscopy-based characterization of the interaction of PriA helicase with stalled DNA replication forks [DNA and Chromosomes] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 In bacteria, the restart of stalled DNA replication forks requires the DNA helicase PriA. PriA can recognize and remodel abandoned DNA replication forks, unwind DNA in the 3'-to-5' direction, and facilitate the loading of the helicase DnaB onto the DNA to restart replication. Single-stranded DNA–binding protein (SSB) is typically present at the abandoned forks, but it is unclear how SSB and PriA interact, although it has been shown that the two proteins interact both physically and functionally. Here, we used atomic force microscopy to visualize the interaction of PriA with DNA substrates with or without SSB. These experiments were done in the absence of ATP to delineate the substrate recognition pattern of PriA before its ATP-catalyzed DNA-unwinding reaction. These analyses revealed that in the absence of SSB, PriA binds preferentially to a fork substrate with a gap in the leading strand. Such a preference has not been observed for 5'- and 3'-tailed duplexes, suggesting that it is the fork structure that plays an essential role in PriA's selection of DNA substrates. Furthermore, we found that in the absence of SSB, PriA binds exclusively to the fork regions of the DNA substrates. In contrast, fork-bound SSB loads PriA onto the duplex DNA arms of forks, suggesting a remodeling of PriA by SSB. We also demonstrate that the remodeling of PriA requires a functional C-terminal domain of SSB. In summary, our atomic force microscopy analyses reveal key details in the interactions between PriA and stalled DNA replication forks with or without SSB. Full Article

cr Crisis at the Border? Not by the Numbers By www.migrationpolicy.org Published On :: Thu, 07 Jun 2018 15:04:06 -0400 Monthly apprehension statistics at the Southwest border have become a preoccupation for the Trump administration, which compares the 2018 numbers to 2017 and declares a crisis. Yet it was 2017, when the "Trump effect" temporarily paused illegal crossings, that was the outlier. Recent trends have reverted to the pattern seen in 2016, a result notable at a time of very low U.S. unemployment, as this commentary explores. Full Article
cr A Wall Cannot Fix Problems at Border; Smart Solutions for Asylum Crisis Can By www.migrationpolicy.org Published On :: Mon, 14 Jan 2019 10:48:47 -0500 What President Trump calls a border crisis is in fact a crisis in the asylum system—one worsened at every turn by his administration’s harsh policies and rhetoric. Rather than spend $5.7 billion on a wall, it would be far more effective to use the money to retool an overwhelmed asylum system, adapt outmatched border enforcement infrastructure to respond to the changing composition of arrivals, and work cooperatively with Mexico to tackle the factors propelling Central Americans to flee.
