Setting prices for items is difficult because one needs to look at prices other substitutable as well as complimentary items. In a co-purchasing network, co-occurence of items can be exploited to tweak item prices for revenue maximization. In our report, we investigate the effects of co-occurrence of items on their prices. In general this problem seems to be NP-Hard. We propose heuristics based...

INTRODUCTION Glutathione S-transferases (GSTs) are phase 2 enzymes responsible for catalyzing the biotransformation of a wide variety of electrophilic compounds, having a crucial role in the detoxification of active metabolites of procarcinogens produced by phase 1 reactions, tying them to glutathione and promoting their excretion in the urine. OBJECTIVES we evaluated GSTM1, GSTT1 and GSTP1 g...

The current scoping study identifies the significant heat transfer effects for a 767 boiling water reactor (BWR) assembly within an isothermal basket opening inside a transport cask. A twodimensional finite volume mesh is constructed that models the assembly components and cover gas. Computational fluid dynamics (CFD) simulations calculate the buoyancy induced gas motion, conduction and radiati...

erbb4 is a susceptibility gene for schizophrenia and ErbB4 signals have been hypothesized to function in a number of cortical developmental processes (Silberberg et al., 2006; Mei and Xiong, 2008). Several recent studies show that the expression of ErbB4 is mainly restricted to GABAergic interneurons (Yau et al., 2003; Woo et al., 2007), specifically, to parvalbumin-positive (PV) fast-spiking (...

A diversity of GABAergic cell types exist within each brain area, and each cell type is thought to play a unique role in the modulation of principal cell output. Basket cells, whose axon terminals surround principal cell somata and proximal dendrites, have a privileged and influential position for regulating the firing of principal cells. This review explores the dichotomy of the two basket cel...

We conducted a literature review of natural orifice transluminal endoscopic surgery (NOTES), focusing on urologic procedures with gastrointestinal tract access, to update on the development of this novel surgical approach. As part of the methods, a comprehensive electronic literature search for NOTES was conducted using PubMed and Cochrane Library from March 2002 to February 2016 for papers rep...

In recent years, immunotherapy has been gradually established as the fourth frequently adopted antitumor therapy, following surgery, chemotherapy and radiotherapy, for advanced urologic malignancies with an improved understanding of theoretical basis, such as molecular biology and immunology. Thereinto, adoptive cellular immunotherapy (ACI) has become one of the hotspots, which comprises a vari...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204940 DESCRIPTION Endoscopic retrograde cholangiopancreatography (ERCP) is the predominate method of removing common bile duct (CBD) calculi. The simplest and quickest way of removing large CBD calculi during ERCP is a mechanical lithotripter to crush the gallstone before remov...

background: evaluation of patient care can lead to finfing out weakness and strengths of the care in order to increase the quality of services. objective: to evaluate the quality of patients cares with continuous bladder irrigation. methods: in an analytic-descriptive research, 48 patients with continuous bladder irrigation who suffered from urologic disorders were studied. data gathering was b...
