Concerns about increasing bacterial resistance to vancomycin, have caused the adult treatment guidelines to recommend higher trough concentrations based on the type and location of infectious disease. Although these recommendations are not specific to children, the values can be extrapolated. This prospective study was designed to evaluate efficacy of current vancomycin dosing recommendations to achieve therapeutic trough serum concentration in pediatric patients. Laboratory data, vancomycin dosing and subsequent serum concentrations of children in a community teaching pediatrics hospital were collected and analyzed...

Activation of PAR1 by activated protein C (APC) and thrombin elicits paradoxical cytoprotective and cytotoxic signaling responses in vascular endothelial cells through cleavage of the receptor at Arg-46 and Arg-41 protease recognition sites, respectively. It has been reported that unlike a disruptive G-protein mediated PAR1 signaling by thrombin, APC induces a protective β-arrestin-2 biased PAR1 signaling by unknown mechanisms. We hypothesize that the occupancy of endothelial protein C receptor (EPCR) by the Gla-domain of protein C/APC is responsible for the β-arrestin-2 biased PAR1 signaling independent of the protease cleavage site...

: Essentials Polyphosphate (polyP) activates mTOR but its role in Wnt/β-catenin signaling is not known. PolyP-mediated cyclin D1 expression (β-catenin target gene) was monitored in endothelial cells. PolyP and boiled platelet-releasates induced the expression of cyclin D1 by similar mechanisms. PolyP establishes crosstalk between mTOR and Wnt/β-catenin signaling in endothelial cells. SUMMARY: Background Inorganic polyphosphate (polyP) elicits intracellular signaling responses in endothelial cells through activation of mTOR complexes 1 and 2...

Optical Coherence Tomography (OCT) is one of the most informative methodologies in ophthalmology and provides cross sectional images from anterior and posterior segments of the eye. Corneal diseases can be diagnosed by these images and corneal thickness maps can also assist in the treatment and diagnosis. The need for automatic segmentation of cross sectional images is inevitable since manual segmentation is time consuming and imprecise. In this paper, segmentation methods such as Gaussian Mixture Model (GMM), Graph Cut, and Level Set are used for automatic segmentation of three clinically important corneal layer boundaries on OCT images...

This report describes a patient with dysphonia for 16 years in combination with asymmetric and progressive decrease in sense and power of both upper and lower extremities for the past 3 years. Electrophysiological study revealed asymmetric conduction block and abnormal sensory action potential in 4 limbs. The vagus nerves palsy and abnormal electrodiagnosis of the limbs led us to diagnose the disease as Lewis and Sumner syndrome, also called multifocal acquired demyelinating sensory and motor neuropathy diagnosis, which improved by corticosteroid consumption to some extent...

Natural pyrite (NP) was treated using oxygen and nitrogen non-thermal plasmas to form modified catalysts. Cleaning effect of the O2 plasma by chemical etching leads to removal of impurities from catalyst surface and sputtering effect of the N2 plasma results in formation of pyrite nanorods. The mentioned plasmas were applied separately or in the order of first O2 and then N2, respectively. The catalytic performance of the plasma-modified pyrites (PMPs) is better than the NP for treatment of Reactive Blue 69 (RB69) in heterogeneous sono-Fenton process (US/H2O2/PMP)...

Decision making often requires simultaneously learning about and combining evidence from various sources of information. However, when making inferences from these sources, humans show systematic biases that are often attributed to heuristics or limitations in cognitive processes. Here we use a combination of experimental and modelling approaches to reveal neural substrates of probabilistic inference and corresponding biases. We find systematic deviations from normative accounts of inference when alternative options are not equally rewarding; subjects' choice behaviour is biased towards the more rewarding option, whereas their inferences about individual cues show the opposite bias...
