Intramedullary spinal cord tumors (IMSCTs) represent a rare entity, accounting for 4%-10% of all central nervous system tumors. Microsurgical resection of IMSCTs is currently considered the primary treatment modality. Intraoperative neurophysiological monitoring (IONM) has been shown to aid in maximizing tumor resection and minimizing neurological morbidity, consequently improving patient outcome. The gold standard for IONM to date is multimodality monitoring, consisting of both somatosensory evoked potentials, as well as muscle-based transcranial electric motor evoked potentials (tcMEPs)...

A weather-based simulation model, called POMICS, was constructed to predict fungicide application scheduling to manage powdery mildew of cucurbits. The model was developed on the principle that conditions favorable for Podosphaera xanthii, a causal pathogen of this crop disease, generate a number of infection cycles in a single growing season. The model consists of two components that: (i) simulate the disease progression of P. xanthii in secondary infection cycles under natural conditions and (ii) predict the disease severity with application of fungicides at any recurrent disease cycles...

AIM: Hepatocellular carcinoma (HCC) is a common outcome of chronic hepatitis C virus (HCV) infection and constitutes the main burden of this disease. The molecular mechanisms underlying the development of HCC are multiple and might involve certain microRNA (miR). Since discordant results have been reported concerning the detection of expression of miR-152 and miR-122 in HCC, our aim was to measure the levels of both miRs in serum and liver samples. METHODS: We analyzed miR-152 and miR-122 expression by RT-qPCR in a serum cohort from 14 HCV-infected patients who developed HCC, 20 HCV+ patients without HCC and 19 control patients...

Recent expansions in health insurance coverage have raised concerns about health care providers' capacity to supply additional services and how that may have affected access to care for people who were already insured. When we examined data for the period 2008-14 from the Medical Expenditure Panel Survey, we found no consistent evidence that increases in the proportions of adults with insurance at the local-area level affected access to care for adults residing in the same areas who already had, and continued to have, insurance...

Transepithelial bicarbonate secretion by human airway submucosal glands and surface epithelial cells is crucial to maintain the pH-sensitive innate defence mechanisms of the lung. cAMP agonists stimulate HCO3(-) secretion via coordinated increases in basolateral HCO3(-) influx and accumulation, as well as CFTR-dependent HCO3(-) efflux at the luminal membrane of airway epithelial cells. Here, we investigated the regulation of a basolateral located, DIDS-sensitive, Cl(-)/HCO3(-) exchanger, anion exchanger 2 (AE2; SLC4A2) which is postulated to act as an acid loader, and therefore potential regulator of HCO3(-) secretion, in human airway epithelial cells...

MicroRNAs have been recognized as critical regulators of gene expression and might affect the risk of venous thrombosis. We aimed to identify 3' untranslated region (UTR) variants in coagulation genes that influence coagulation factor levels and venous thrombosis risk. The 3'UTR of coagulation genes were sequenced in subjects with extremely high or low plasma levels of these factors in two case-control studies. In total, 28 variants were identified. Five single nucleotide polymorphisms (SNPs) were predominantly present in one extreme level group (F2 rs1799963, F8 rs1050705 and F11 rs4253429, rs4253430 and rs1062547)...
