PURPOSE To assess the factors influencing multiparametric (MP) magnetic resonance (MR) imaging accuracy in estimating prostate cancer histologic volume (Vh). MATERIALS AND METHODS A prospective database of 202 patients who underwent MP MR imaging before radical prostatectomy was retrospectively used. Institutional review board approval and informed consent were obtained. Two independent radio...

An estuarine methanotroph was isolated from sediment enrichments and designated Methylobacter sp. strain BB5.1. In cells grown on medium with added copper, oxidation of methane and trichloroethylene occurred with similar Ks values, but the Vmax for trichloroethylene oxidation was only 0.1% of the methane oxidation Vmax. Cells grown on low-copper medium did not oxidize trichloroethylene and show...

in present study, the kinetic parameters of purified trypsin from pyloric caeca of common kilka (c.cultriventris caspia) were measured using the amidolytic (bapna) and esterolytic (tame) substrates. the results of the kinetic comparison between bapna and tame substrates showed that kinetic parameters including maximum velocity (vmax), catalytic constant (kcat) and catalytic efficiency (kcat/km)...

Decomposition of soil organic matter (SOM) is mediated by microbial extracellular hydrolytic enzymes (EHEs). Thus, given the large amount of carbon (C) stored as SOM, it is imperative to understand how microbial EHEs will respond to global change (and warming in particular) to better predict the links between SOM and the global C cycle. Here, we measured the Michaelis–Menten kinetics [maximal r...

El objetivo del estudio fue evaluar el efecto rizoma seco de jengibre (RSJ) sobre la fermentación ruminal in vitro, producción metano (CH4) y dióxido carbono (CO2). Los tratamientos fueron dietas con 0, 1, 3, 5, 10, 20 40% RSJ incubados durante 72 horas en vitro líquido obtenido dos novillos machos. Se determinó degradabilidad materia seca(DMS), gas (PG), CH4 CO2, volumen máximo (Vmax), fase re...

Kentlerde oluşan hızlı nüfus artışı hareketliliğin de artmasına neden olmuştur. Hareketliliğin sağlanması için insanların ve insanlara ait yüklerin taşınması çeşitli ulaşım araçlarıyla yapılmaktadır. Gerek şehir içi gerekse şehirlerarası ulaşımda raylı sistemlerin önemi her geçen gün artmaktadır. Günümüz modern demiryolu hatlarında hem ucuz çevreye duyarlılığı nedeni ile elektrikli hatları terc...

Background: Phospholipases are one of the numerous enzymes found in Naja mossambica venom. They play a major role snakebite envenomation, and also responsible for hydrolysis phospholipid, disrupting membrane integrity. In this study, we evaluated effect Vernonia amygdalina on Phospholipase activity from (Cobra) Results: Partially purified phospholipase had maximal velocity (Vmax) Michaelis Ment...
