The accelerated development of technology over the last three decades has driven biological sciences to high-throughput profiling experiments, now broadly referred to as systems biology. The unprecedented improvement of analytical instrumentation has opened new avenues for more complex experimental designs and expands the knowledge in genomics, proteomics, and other omics fields. Despite the collective efforts of hundreds of researchers, gleaning all the expected information from omics experiments is still quite far. This paper summarizes what has been learned from high-throughput proteomics studies thus far, and what is believed should be done to reveal even more valuable information from such studies. It is drawn from the background in using proteomics to study human immunodeficiency virus 1 infection of macrophages and/or T cells, but it is believed that some conclusions will be more broadly applicable.Shape-selective catalysis plays a key role in chemical synthesis. Porous nanomaterials with uniform pore structures are ideal supports for metal nanoparticles (MNPs) to generate efficient shape-selective catalysis. However, many commercial irregular porous nanomaterials face the challenge to realize satisfactory shape selectivity due to the lack of molecular sieving structures. Herein, we report a concept of creating shape selectivity in MNPs/porous nanomaterials through intentionally poisoning certain MNPs using suitable modifiers. The remaining MNPs within the substrates can cooperate with the channels to generate selectivity. Such a strategy not only applies to regular porous nanomaterials (such as MOFs, zeolites) but also extended to irregular porous nanomaterials (such as active carbon, P25). Potentially, the matching among different MNPs, corresponding modifiers, and porous nanomaterials makes our strategy promising in selective catalytic systems.Crowding in emergency departments (EDs) is increasing in many health systems. Previous studies of the relationship between crowding and care quality are limited by the use of data from single hospitals, a focus on particular patient groups, a focus on a narrow set of quality measures, and use of crowding measures which induce bias from unobserved hospital and patient characteristics. Using data from 139 hospitals covering all major EDss in England, we measure crowding using quasi-exogenous variation in the volume of EDs attendances and examine its impacts on indicators of performance across the entire EDs care pathway. We exploit variations from expected volume estimated using high-dimensional fixed effects capturing hospital-specific variation in attendances by combinations of month and hour-of-the-week. Unexpected increases in attendance volume result in substantially longer waiting times, lower quantity and complexity of care, more patients choosing to leave without treatment, changes in referral and discharge decisions, but only small increases in reattendances and no increase in mortality. Causal bounds under potential omitted variable bias are narrow and exclude zero for the majority of outcomes. Results suggest that physician and patient responses may largely mitigate the impacts of demand increases on patient outcomes in the short-run.Inhibition of mitochondrial reactive oxygen species (ROS) and subsequent damage-associated molecular patterns (DAMPs)-induced inflammatory responses could be a novel target in clinical islet transplantation. We investigated the protective effects of NecroX-7, a novel clinical-grade necrosis inhibitor that specifically targets mitochondrial ROS, against primary islet graft failure. Islets from heterozygote human islet amyloid polypeptide transgenic (hIAPP+/- ) mice and nonhuman primates (NHPs) were isolated or cultured with or without NecroX-7 in serum-deprived medium. Supplementation with NecroX-7 during hIAPP+/- mouse islet isolation markedly increased islet viability and adenosine triphosphate content, and attenuated ROS, transcription of c-Jun N-terminal kinases, high mobility group box 1, interleukin-1beta (IL-1 β ), IL-6, and tumor necrosis factor-alpha. Supplementation of NecroX-7 during serum-deprived culture also protected hIAPP+/- mouse and NHP islets against impaired viability, serum deprivation-induced ROS, proinflammatory response, and accumulation of toxic IAPP oligomer. Supplementation with NecroX-7 during isolation or serum-deprived culture of hIAPP+/- mouse and NHP islets also improved posttransplant glycemia in the recipient streptozotocin-induced diabetic hIAPP-/- mice and BALB/c-nu/nu mice, respectively. In conclusion, pretransplant administration of NecroX-7 during islet isolation and serum-deprived culture suppressed mitochondrial ROS injury, generation of DAMPs-induced proinflammatory responses, and accumulation of toxic IAPP oligomers ex vivo, and improved posttransplant glycemia in vivo.The case report aims to reveal de Winter's electrocardiogram (ECG) pattern as an equivalent to anterior ST-segment elevation myocardial infarction (STEMI). We report a case of a 49-year-old man with a history of smoking who presented to the emergency department with a 1 day history of chest pain that was exacerbated 5 h prior to presentation. Detailed clinical investigations and coronary angiographic characteristics were recorded. The first ECG of the patient was consistent with de Winter syndrome. Acute coronary artery angiography showed that the proximal left anterior descending coronary artery was completely occluded after the first diagonal branch artery was given off. A percutaneous coronary intervention was immediately performed. Our case indicates that early identification and diagnosis of such ECGs and timely reperfusion therapy of de Winter syndrome as a STEMI equivalent are required to improve the prognosis of such patients.Historically, patients with restrictive (RCM) and hypertrophic cardiomyopathy (HCM) experienced longer wait-times for heart transplant (HT) and increased waitlist mortality. Recently, a new HT allocation system was implemented in the United States. We sought to determine the impact of the new HT system on RCM/HCM patients. Adult patients with RCM/HCM listed for HT between November 2015 and September 2019 were identified from the UNOS database. Patients were stratified into two groups old system and new system. We identified 872 patients who met inclusion criteria. Of these, 608 and 264 were classified in the old and new system groups, respectively. The time in the waitlist was shorter (25 vs. LNG-451 cost 54 days, P less then .001), with an increased frequency of HT in the new system (74% vs. 68%, P = .024). Patients who were transplanted in the new system had a longer ischemic time, increased use of temporary mechanical circulatory support and mechanical ventilation. There was no difference in posttransplant survival at 9 months (91.
