This work reports the obtention of nanocompounds from epoxy resin (EP) with graphenes at three different oxidation degrees (GO1, GO2, and GO3), functionalized 3-glycidyloxypropyl trimethoxysilane (GPTMS), graphene concentrations (1%, 2%, 3%). The aim is to improve GO compatibility in EP obtain a nanocompound synergistic properties. Ultrasonic bath was used disperse GO, factor effective interact...

A large deviation technique is used to calculate the microcanonical entropy function s(v,m) of the mean-field φ4-model as a function of the potential energy v and the magnetization m. As in the canonical ensemble, a continuous phase transition is found. An analytical expression is obtained for the critical energy vc(J) as a function of the coupling parameter J .

Fabrication and electrochemical characterization of a sensor for the determination of epinephrine (EP), uric acid (UA) and folic acid (FA) is described. The sensor  was prepared using carbon paste electrode (CPE) modified with 3,4-dihydroxybenzaldehyde-2,4-dinitrophenylhydrazone (DDP) and carbon nanotubes (CNTs), which makes the modified electrode highly sensitive for the electrochemical detect...

Chromatin organization can be probed by Chromosomal Capture (5C) data, from which the encounter probability (EP) between genomic sites is presented in a large matrix. This matrix is averaged over a large cell population, revealing diagonal blocks called Topological Associating Domains (TADs) that represent a sub-chromatin organization. To study the relation between chromatin organization and ge...

background: one of the affecting factors in disturbance process of spermatogenesis is chemotherapeutic-induced oxidative stress resulted from cyclophosphamide (cp) treatment which leads to diminished sperm quality via interference in spermatogenesis process. objective: this study was conducted to investigate the effects of ethyl pyruvate (ep) in reducing the cp-induced side effects on reproduct...

background: measurement of serum β-hcg concentration commonly used to diagnose tubal ectopic pregnancy (ep) and follow up patients treated conservatively.objective: the aim of this study was to determine the predictive value of maternal serum β-hcg concentration in ruptured tubal ectopic pregnancy to help physicians identify those women who are at greatest risk.materials and methods: this is a ...

In this paper, a nanostructured modified electrode was fabricated by incorporating of 2,2′-[1,9-nonanediylbis(nitriloethylidyne)]-bis-hydroquinone (NNH) as a newly synthesized modifier and TiO2 nanoparticles to the carbon paste (MTCPE) and then was used for the electroanalysis of epinephrine (EP). The electrochemical studies were carried out by using cyclic voltammetry, chronoamperom...

Four E-prostanoid (EP) receptors, designated EP(1), EP(2), EP(3), and EP(4), mediate the cellular effects of prostaglandin E(2) (PGE(2)). The present studies pharmacologically characterize the vasopressor and vasodepressor EP receptors in wild-type mice (EP(2)(+/+) mice) and mice with targeted disruption of the EP(2) receptor (EP(2)(-/-) mice). Mean arterial pressure (MAP) was measured via a ca...

Introduction: Ischemic stroke is the leading cause of morbidity and the third most common cause of mortality in USA. The identification of the culprit thrombotic lesion, micro-emboli and the source of the embolus are all critical to patient management. EP2104R [1], a fibrin-specific molecular MR agent, was previously shown to enhance arterial and venous thrombi in large animal models (swine, ra...
