We report on familial 5 epilepsy patients with autosomal dominant inheritance of a novel heterozygous NUS1 frameshift mutation. All patients had cerebellar ataxia and tremor. Three patients were diagnosed with childhood absence epilepsy, 1 patient with generalized epilepsy, and 1 patient with parkinsonism without epilepsy. Our cases and previously reported cases with deletions of chromosome 6q22 that include NUS1 share these common symptoms. In a cellular experiment, NUS1 mutation led to a substantial reduction of the protein level of NUS1. NUS1 mutation could contribute to epilepsy pathogenesis and also constitute a distinct syndromic entity with cerebellar ataxia and tremor.Heat stress is a major environmental factor limiting plant productivity and quality in agriculture. Cucumber, one of the most important vegetables among cucurbitaceae, prefers to grow in a warm environment. Until now the molecular knowledge of heat stress in cucumber remained unclear. In this study, we performed transcriptome analysis using two diverse genetic cucumber cultivars, L-9 and A-16 grown under normal and heat stress. L-9 displayed heat-tolerance phenotype with higher superoxide dismutase enzyme (SOD) enzyme activity and lower malondialdehyde (MDA) content than A-16 under heat stress. RNA-sequencing revealed that a total of 963 and 2778 genes are differentially expressed between L-9 and A-16 under normal and heat stress respectively. In addition, we found that differentially expressed genes (DEGs) associated with plant hormones signally pathway, transcription factors, and secondary metabolites showed significantly change in expression level after heat stress, which were confirmed by quantitative real-time PCR assay. Our results not only explored several crucial genes involved in cucumber heat resistance, but also provide a new insight into studying heat stress.Sleep loss in the rat increases blood-brain barrier permeability to circulating molecules by disrupting interendothelial tight junctions. Despite the description of the ultrastructure of cerebral microvessels and the evidence of an apparent pericyte detachment from capillary wall in sleep restricted rats the effect of sleep loss on pericytes is unknown. Here we characterized the interactions between pericytes and brain endothelial cells after sleep loss using male Wistar rats. Animals were sleep-restricted 20 h daily with 4 h sleep recovery for 10 days. At the end of the sleep restriction, brain microvessels (MVs) were isolated from cerebral cortex and hippocampus and processed for Western blot and immunocytochemistry to evaluate markers of pericyte-endothelial cell interaction (connexin 43, PDGFR-β), tight junction proteins, and proinflammatory mediator proteins (MMP9, A2A adenosine receptor, CD73, NFκB). Sleep restriction reduced PDGFR-β and connexin 43 expression in MVs; in addition, scanning electron microscopy micrographs showed that pericytes were detached from capillary walls, but did not undergo apoptosis (as depicted by a reduced active caspase-3 expression). Sleep restriction also decreased tight junction protein expression in MVs and increased BBB permeability to low- and high-molecular weight tracers in in vivo permeability assays. Those alterations seemed to depend on a low-grade inflammatory status as reflected by the increased expression of phosphorylated NFκB and A2A adenosine receptor in brain endothelial cells from the sleep-restricted rats. Our data show that pericyte-brain endothelial cell interaction is altered by sleep restriction; this evidence is essential to understand the role of sleep in regulating blood-brain barrier function.Objective Contrasting results are reported on the clinical course of acute diverticulitis (AD) in the geriatric population. The aim of this study is to compare the AD clinical outcomes between patients aged up to 80 years and those ≥80 years. Methods A total of 1139 patients were enrolled 276 patients aged ≥80 years were compared to a group of 863 patients aged less then 80 years. The primary outcome was to compare the overall mortality. Secondary outcomes included major complications, in-hospital length of stay (LOS), and need for surgical procedures. Results Patients ≥80 years with AD had different clinical presentation compared to younger patients they had less fever (21.4% vs. 35.2%; P less then 0.001) and abdominal pain (47.8% vs. 65.6%; P less then 0.001) rates, but a higher digestive tract bleeding (31.5% vs. 12.3%; p less then 0.001), and fatigue (12.7% vs. 7.1%; p = 0.004) rates. Median LOS, cumulative major complications and mortality rates were higher for patients ≥80 years. Multivariate analysis identified age, absence of abdominal pain, and dyspnea at presentation as independent predictors of intra hospital death or major complications. Conclusions Patients with AD and age ≥80 years have a higher mortality rate and cumulative major complications as compared younger patients. Invasive treatments were associated to a poor prognosis in this group.Vinyl fluorides play an important role in drug development as bioisosteres for peptide bonds and are found in a range of bioactive molecules. The discovery of safe, general and practical procedures to prepare vinyl fluorides from readily available precursors remains a synthetic challenge. The metal-free hydrofluorination of alkynes constitutes an attractive though elusive strategy for their preparation. Here we introduce an inexpensive and easily-handled reagent that enabled the development of simple and scalable protocols for the regioselective hydrofluorination of alkynes to access both the E and Z isomers of vinyl fluorides. These conditions were suitable for a diverse collection of alkynes, including several highly-functionalized pharmaceutical derivatives. Computational and experimental mechanistic studies support C-F bond formation through vinyl cation intermediates, with the ( E )- and ( Z )-hydrofluorination products forming under kinetic and thermodynamic control, respectively.Being a critical neurodevelopmental stage that is affected by social conditions, the period of adolescence was chosen as the age of examining possible modification of alcohol neurobehavioral effects by overcrowding. Adolescent male rats (postnatal day 35±1) were subjected to overcrowding and/or injected with ethanol, 2 g/kg, 20% w/v, (i.p.) for one week. 24 h after the last dose, motor, exploratory behavior, sociability and fear responses were assessed using open field, social interaction and defensive probe burying tests, respectively. Wet brain tissue nitric oxide and reduced glutathione contents as well as monoamine levels, namely dopamine, norepinephrine and serotonin, in addition to 5-HIAA were estimated. Overcrowding increased social play and freezing time. Alcohol administration under overcrowding condition impaired sociability and interfered with active fear response. Alcohol in normal or in under overcrowding condition, impaired motor and exploratory behavior and increased anxiety. These results indicate that concomitant exposure of male adolescent rats to overcrowding and alcohol induced adverse behavioral changes.High-Z nanoparticles have emerged as a novel type of radiosensitizers due to their relatively large X-ray cross-section and ability to enhance radical production under irradiation. Recently, CaWO4 nanoparticles have been prepared and their potential as a radiosensitizer has been demonstrated. Herein, we investigated BaWO4 nanoparticles as a novel type of alkaline-earth metal tungstate radiosensitizer for radiotherapy (RT). We synthesized BaWO4 nanoparticles using hydrothermal reaction and coated them with polyvinylpyrrolidone (PVP). We found that BaWO4 nanoparticles could more efficiently enhance hydroxyl radical production under irradiation than CaWO4 nanoparticles. When tested in vitro, BaWO4 nanoparticles showed lower toxicity than CaWO4 nanoparticles in the absence of irradiation, but induced more significant oxidative stress under irradiation. When tested in vivo, BaWO4 nanoparticles led to more efficient tumor inhibition without causing systemic toxicity. Overall, our results suggest that BaWO4 nanoparticles can efficiently enhance RT and hold great potential as a novel type of radiosensitizing agent.Rationale While centrilobular (CLE) and paraseptal (PSE) emphysema are commonly identified on multi-detector computed tomography (MDCT), little is known about the pathology associated with PSE compared to CLE. Objective To assess the pathological differences between PSE and CLE in chronic obstructive pulmonary disease (COPD). Methods Air-inflated frozen lung specimens (n=6) obtained from patients with severe COPD treated by lung transplantation were scanned with MDCT. Frozen tissue cores were taken from central (n=8) and peripheral (n=8) regions of each lung, scanned with microCT, and processed for histology. The core locations were registered to the MDCT and a percentage of PSE or CLE was assigned by radiologists to each of the regions. MicroCT scans were used to measure number and structural change of terminal bronchioles. Further, microCT based volume fractions of centrilobular (CLE%) and paraseptal (PSE%) emphysema allowed classifying cores into mild emphysema, CLE-dominant, and PSE-dominant. Measurements and main results PSE% measured on MDCT and microCT were positively associated (p=0.015). Number of terminal bronchioles per ml of lung and cross-sectional lumen area were significantly lower while wall area percent was significantly higher in CLE-dominant compared to mild emphysema and PSE-dominant regions (all p0.5). Immunohistochemistry showed significantly higher infiltration of neutrophils (p=0.002), but not of macrophages, CD4, CD8, or B cells, in PSE compared to CLE regions. Conclusions The terminal bronchioles are relatively preserved while neutrophilic inflammation is increased in PSE-dominant regions compared to CLE-dominant regions in patents with COPD.A veterinarian and pet owner survey (Project Jake) examined the use and safety of isoxazoline parasiticides given to dogs. Data were received during August 1-31, 2018 from a total of 2,751 survey responses. Forty-two percent (1,157) reported no flea treatment or adverse events (AE), while 58% (1594) had been treated with some parasiticide for flea control, and of those that received a parasiticide, the majority, or 83% (1,325), received an isooxazoline. When any flea treatment was given, AE were reported for 66.6% of respondents, with no apparent AE noted for 36.1%. Project Jake findings were compared to a retrospective analysis of publicly available Food and Drug Administration (FDA) and European Medicines Agency (EMA) reported AE. The number of total AE reported to FDA and EMA were comparable, although a 7 to 10 times higher occurrence of death and seizures was reported from the EMA or from outside the United States (US). Serious AE responses for death, seizures and neurological effects reported in our survey were higher than the FDA but moderately lower than the EMA reports. These sizable global data sets combined with this pre- and post-parasiticide administration survey indicated that isoxazoline neurotoxicity was not flea- and tick-specific. Post-marketing serious AE were much higher than in Investigational New Drug (IND) submissions. Although the labels have recently been updated, dogs, cats and their caregivers remain impacted by their use. Cyclic GMP-AMP These aggregate data reports support the need for continued cross-species studies and critical review of product labelling by regulatory agencies and manufacturers.
