Curcumin significantly improved blood glucose level, redox status, cellular stress, and decreased INF-γ and Bax levels, down-regulated GRP78 and ATF-4 expression, meanwhile, up-regulated Bcl2 and ChAT expression in hippocampus. Histological findings proved the biochemical and molecular findings. Our results support curcumin as a potential neuro-protective agent against diabetes induced hippocampal neurodegeneration.Hyperglycemia has been shown to counterbalance the beneficial effects of tissue plasminogen activator (tPA) and increase the risk of intracerebral hemorrhage in ischemic stroke. Thioredoxin interacting protein (TXNIP) mediates hyperglycemia-induced oxidative damage and inflammation in the brain and reduces cerebral glucose uptake/utilization. We have recently reported that TXNIP-induced NLRP3 (NOD-like receptor pyrin domain-containing-3) inflammasome activation contributes to neuronal damage after ischemic stroke. Here, we tested the hypothesis that tPA induces TXNIP-NLRP3 inflammasome activation after ischemic stroke, in hyperglycemic mice. Acute hyperglycemia was induced in mice by intraperitoneal (IP) administration of a 20% glucose solution. This was followed by transient middle cerebral artery occlusion (t-MCAO), with or without intravenous (IV) tPA administered at reperfusion. The IV-tPA exacerbated hyperglycemia-induced neurological deficits, ipsilateral edema and hemorrhagic transformation, and accentyperglycemic stroke.As a result of increased awareness of wide-spread methodological bias and obvious translational roadblocks in subarachnoid hemorrhage (SAH) research, various checklists and guidelines were developed over the past decades. This systematic review assesses the overall methodological quality of preclinical SAH research. An electronic search for preclinical studies on SAH revealed 3415 potential articles. Of these, 765 original research papers conducted in vivo in mice, rats, rabbits, cats, dogs, pigs, goats, and non-human primates with a focus on brain damage related to delayed cerebral vasospasm and early brain injury met the inclusion criteria. We found methodological shortcomings still to prevail in preclinical SAH research. In addition, basic animal characteristics were typically well described but important technical parameters of SAH induction were often underreported. None of the species, models, or techniques used in preclinical SAH research was methodologically superior to the others. Methodological quality of preclinical SAH research was independent of the number of citations or impact factor of a publication. Consequently, we suggest the SAH research community should consider strategies to improve preclinical research quality in their field, such as public platforms to (pre)register preclinical experiments, consequent support of open science policies, stricter editorial (and reviewer) control of (pre)existing guidelines, and increased efforts in education and training of good laboratory practice for the next generation of researchers.OBJECTIVE Ciliated muconodular papillary tumor (CMPT) is a rare lung tumor that was first reported in 2002. This study assessed 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) findings of CMPT of the lung. METHODS FDG PET/CT findings of 15 patients (eight men and seven women; median age, 67 years) with surgically resected CMPTs were retrospectively analyzed. Size, location, and maximum standardized uptake values (SUVmax) of CMPTs were measured. Histopathological features of the resected tumors were assessed and compared with the FDG PET/CT findings. RESULTS CMPTs were detected as a small pulmonary nodule in all 15 patients. Twelve of 15 tumors were found in the lower lobe of the lung. Mean maximal diameter of the tumors was 9 mm (range 6-14 mm). All but one tumor showed low FDG uptake, with a SUVmax ranging from 0.57 to 1.35. The remaining tumor showed moderate FDG uptake, with a SUVmax of 3.67. Pathologically, tumors with low FDG uptake contained various amounts of mucin and no or only a small amount of lymphocyte infiltration. In contrast, the tumor with moderate FDG uptake had a large cellular component and prominent lymphocyte infiltration. CONCLUSION CMPT typically shows low FDG uptake.In highly populated areas, environmental surveillance of wastewater and surface waters is a key factor to control the circulation of viruses and risks for public health. Hepatitis E virus (HEV) genotype 3 is considered as an emerging pathogen in industrialized countries. U73122 purchase Therefore, this study was carried out to determine the prevalence of HEV in environmental waters in urban and suburban regions in Germany. HEV was monitored in water samples using quantitative RT-PCR (RT-qPCR) and nested RT-PCR without or with virus concentration via polyethylene glycol precipitation or ultracentrifugation. By RT-qPCR, 84-100% of influent samples of wastewater treatment plants were positive for HEV RNA. Genotypes HEV-3c and 3f were identified in wastewater, with HEV-3c being the most prevalent genotype. These data correlate with subtypes identified earlier in patients from the same area. Comparison of wastewater influent and effluent samples revealed a reduction of HEV RNA of about 1 log10 during passage through wastewater treatment plants. In addition, combined sewer overflows (CSOs) after heavy rainfalls were shown to release HEV RNA into surface waters. About 75% of urban river samples taken during these CSO events were positive for HEV RNA by RT-qPCR. In contrast, under normal weather conditions, only around 30% of river samples and 15% of samples from a bathing water located at an urban river were positive for HEV. Median concentrations of HEV RNA of all tested samples at this bathing water were below the limit of detection.PURPOSE Children with Down's syndrome (DS) are prone to respiratory tract infections (RTIs) due to anatomical variation, immune system immaturity and comorbidities. However, evidence on RTI-related healthcare utilisation, especially in primary care, is incomplete. In this retrospective cohort study, we use routinely collected primary and secondary care data to quantify RTI-related healthcare utilisation in children with DS and matched controls without DS. METHODS Retrospective cohort study of 992 children with DS and 4874 matched controls attending English general practices and hospitals as identified in Clinical disease research using LInked Bespoke studies and Electronic health Records (CALIBER) from 1997 to 2010. Poisson regression was used to calculate consultation, hospitalisation and prescription rates, and rate ratios. Wald test was used to compare risk of admission following consultation. The Wilcoxon rank-sum test was used to compare length of stay by RTI type and time-to-hospitalisation. RESULTS RTI-related healthcare utilisation is significantly higher in children with DS than in controls in terms of GP consultations (adjusted RR 1.
