Many emergency departments have implemented sepsis protocols since the 2001 publication of results from the early goal-directed therapy trial, which showed early targeted resuscitation lowers mortality. As part of an attempt to improve clinical and operational outcomes for emergency departments across British Columbia, we reviewed sepsis management literature and considered sepsis protocol implementation in the province’s emergency departments. During the literature review we found that many observational studies confirmed an association between implementation of emergency sepsis protocols and decreased mortality...

Diabetes mellitus, a kind of chronic metabolic disease, has become one of major threats to human health with an increasing incidence. As a basic pathology of chronic complications related to diabetes mellitus, cerebral microangiopathy is mainly found in patients with Alzheimer's disease and lacunar infarction, and becomes one of the main reasons of death and disability in diabetic patients. The pathogenesis of cerebral microangiopathy is complicated, involving such signal pathways as metabolic abnormalities of polyol, saccharification hyperactivity, oxidative stress, abnormal transport of amyloid-β across blood-brain barrier and protein kinase C activation...

Aspiration pneumonia is a cause of mortality in the elderly. Evaluating swallowing function is important. Videofluoroscopy and flexible endoscopic evaluation of swallowing are comparable; however, observing all swallowing dynamics is impossible using the latter approach. We examined the significance of flexible endoscopic evaluation of swallowing using videofluoroscopy. Thirty-seven patients with dysphagia [70.0 ± 8.9 (range 49-84) years] were included. In random order, patients underwent videofluoroscopy with 10 cc contrast material, once without, and once with an endoscope inserted...

Inadequate infrastructural networks can be detrimental to society if transport between locations becomes hindered or delayed, especially due to natural hazards which are difficult to control. Thus determining natural hazard susceptible areas and incorporating them in the initial planning process, may reduce infrastructural damages in the long run. The objective of this study was to evaluate the usefulness of expert judgments for assessing natural hazard susceptibility through a spatial multi-criteria analysis approach using hydrological, geological, and land use factors...

On 6 January 2016, the Democratic People's Republic of Korea announced to have conducted its fourth nuclear test. Analysis of the corresponding seismic waves from the Punggye-ri nuclear test site showed indeed that an underground man-made explosion took place, although the nuclear origin of the explosion needs confirmation. Seven weeks after the announced nuclear test, radioactive xenon was observed in Japan by a noble gas measurement station of the International Monitoring System. In this paper, atmospheric transport modelling is used to show that the measured radioactive xenon is compatible with a delayed release from the Punggye-ri nuclear test site...

Control of Ca(2+) flux between the cytosol and intracellular Ca(2+) stores is essential for maintaining normal cellular function. It has been well established in both neuronal and non-neuronal cells that stromal interaction molecule 1 (STIM1) initiates and regulates refilling Ca(2+) into the endoplasmic reticulum (ER). Here, we describe a novel, additional role for STIM1, regulation of free cytosolic Ca(2+) and consequent control of spike firing in neurons. Among central neurons, cerebellar Purkinje neurons express the highest level of STIM1 and they fire continuously in the absence of stimulation, making somatic Ca(2+) homeostasis of particular importance...

Advances in robotic medicine have been adopted by various surgical subspecialties as the benefits of this technology become more readily apparent: precision in narrow operative windows, tremor controlled movements, and modestly improved outcomes, among others. Vascular neurosurgery, in particular, remains open to newer and more cutting edge treatment options for complex pathologies, and robotics may be on the horizon for such advances. We seek to provide a broad overview of these innovations in vascular neurosurgery for both practitioners well acquainted with robotics and those seeking to become more familiar...

The scaffold protein X-ray repair cross-complementing 1 (XRCC1) interacts with multiple enzymes involved in DNA base excision repair and single-strand break repair (SSBR) and is important for genetic integrity and normal neurological function. One of the most important interactions of XRCC1 is that with polynucleotide kinase/phosphatase (PNKP), a dual-function DNA kinase/phosphatase that processes damaged DNA termini and that, if mutated, results in ataxia with oculomotor apraxia 4 (AOA4) and microcephaly with early-onset seizures and developmental delay (MCSZ)...

Purpose:KRAS-activating mutations are the most common oncogenic driver in non-small cell lung cancer (NSCLC), but efforts to directly target mutant KRAS have proved a formidable challenge. Therefore, multi-targeted therapy may offer a plausible strategy to effectively treat KRAS-driven NSCLCs. Here, we evaluate the efficacy and mechanistic rationale for combining mTOR and WEE1 inhibition as a potential therapy for lung cancers harboring KRAS mutations. <p>Experimental Design: We investigated the synergistic effect of combining mTOR and WEE1 inhibitors on cell viability, apoptosis, and DNA damage repair response using a panel of human KRAS-mutant and wild type NSCLC cell lines and patient-derived xenograft cell lines...

We aimed to characterize and target drug-tolerant BRCA1-deficient tumor cells that cause residual disease and subsequent tumor relapse.<br /><br />Experimental Design: We studied responses to various mono- and bifunctional alkylating agents in a genetically engineered mouse model for BRCA1/p53-mutant breast cancer. Due to the large intragenic deletion of the Brca1 gene, no restoration of BRCA1 function is possible, and therefore no BRCA1-dependent acquired resistance occurs. To characterize the cell cycle stage from which Brca1(-/-);p53(-/-) mammary tumors arise after cisplatin treatment, we introduced the fluorescent ubiquitination-based cell cycle indicator (FUCCI) construct into the tumor cells...

Study Objectives: Extracting regularities from stimuli in our environment and generalizing these to new situations are fundamental processes in human cognition. Sleep has been shown to enhance these processes, possibly by facilitating reactivation-triggered memory reorganization. Here, we assessed whether cued reactivation during slow wave sleep (SWS) promotes the beneficial effect of sleep on abstraction of statistical regularities. Methods: We used an auditory statistical learning task, in which the benefit of sleep has been firmly established...

The physicochemical and powder properties of citrus pectins varying in molecular weight and degree of esterification (DE) were characterized. All the pectins were flake particles with average sizes of around 84-107μm in diameter. They were amorphous solids and classified as being from slightly to moderately hygroscopic. Pomelo pectin possessed passable to poor flowability while the others were classified as having fair flowability. Heckel's analysis indicated that all pectins underwent plastic deformation under compression...

Cannabidiol (CBD), the main nonpsychotomimetic compound from Cannabis sativa, inhibits experimental seizures in animal models and alleviates certain types of intractable epilepsies in patients. Its pharmacological profile, however, is still uncertain. Here we tested the hypothesis that CBD anticonvulsant mechanisms are prevented by cannabinoid (CB1 and CB2) and vanilloid (TRPV1) receptor blockers. We also investigated its effects on electroencephalographic (EEG) activity and hippocampal cytokines in the pentylenetetrazole (PTZ) model...

Cross linking of the IgE receptor (FcεRI) on mast cells plays a critical role in IgE-dependent allergy including allergic rhinitis, asthma, anaphylaxis, and delayed type hypersensitivity reactions. The Ca2+ activated K+ channel, KCa3.1, plays a critical role in IgE-stimulated Ca2+ entry and degranulation in mast cells by helping to maintain a negative membrane potential, which provides an electrochemical gradient to drive Ca2+ influx. Of the 3 classes of PI3K, the class II PI3Ks are the least studied and little is known about the roles for class II PI3Ks in vivo in the context of the whole organism under normal and pathological conditions...
