Oxidative stress plays a crucial role in the development of several liver diseases. Many natural polyphenols can attenuate oxidative stress and liver injury. In this study, a phytochemical profiling of a methanol extract from leaves of Syzygium samarangense revealed 92 compounds belonging to flavonoids, phenolic acids, condensed tannins, and ellagitannins. The S. samarangense extract exhibited a n

High-frequency in situ measurements at Gosan (Jeju Island, Korea) during November 2007 to December 2008 have been combined with interspecies correlation analysis to estimate national emissions of halogenated compounds (HCs) in East Asia, including the chlorofluorocarbons (CFCs), halons, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6),

Activating Notch1 mutations have been reported in human T-line-age acute lymphoblastic leukemia (T-ALL) and lymphomas from genetically modified mice. We report that Notch1 is a prevalent and major mutational target in chemically induced mouse lymphoma. The regions of the gene that are frequently mutated are the heterodimerization domain and the N-terminal ligand-binding region, important for prote

A method is presented for the determination of aromatic amines in aqueous extracts of polyurethane (PUR) foam. The method is based on the extraction of PUR foam using aqueous acetic acid (0.1%, w/v) followed by determination of extracted aromatic amines using hydrophilic interaction liquid chromatography (HILIC) and tandem mass spectrometry (MS/MS) with positive electrospray ionisation. The inject

Background: No studies to specifically determine the prevalence of contact allergy to acrylates/methacrylates in patch tested populations have been published. Objectives: To determine the prevalence of acrylate/methacrylate allergy in all patients tested to the baseline patch test series. Methods: Five acrylate/methacrylate allergens (2-hydroxyethyl methacrylate, methyl methacrylate, ethylene glyc

An adsorbent was developed from mature leaves and stem bark of the Neem (Azadirachta indica) tree for removing zinc from water. Adsorption was carried out in a batch process with several different concentrations of zinc by varying pH. The uptake of metal was very fast initially, but gradually slowed down indicating penetration into the interior of the adsorbent particles. The data showed that opti

Methodological aspects of planar gamma scintigraphy used to quantify pulmonary aerosol deposition were investigated using an experimental dry powder formulation. Particles of micronized salbutamol sulphate were labelled with technetium-99m and admixed to an ordered mixture of unlabelled micronized salbutamol sulphate and larger carrier particles of lactose. The radioaerosol was administered to 24

Objective: To estimate whether obese women have an increased risk of orofacial clefts in their offspring, compared with average-weight women. Design and Participants: The study was based on information on maternal body mass index (BMI) collected in early pregnancy and on the existence of orofacial clefts in the offspring, ascertained from multiple sources. The study included 1686 women who had inf

Background: Persistent left superior vena cava (LSVC) is one of the common anomalies of the systemic veins. Its prevalence is 0.1-0.3% in the general population and is more common with congenital heart disease (CHD). The importance of detecting persistent LSVC prior to cardiac surgery is paramount for systemic veins cannulations. Aim: The aim was to evaluate the prevalence of persistent LSVC in pa

The properties of the amyloid-beta peptide that lead to aggregation associated with Alzheimer's disease are not fully understood. This study aims at identifying conformational differences among four variants of full-length Abeta42 that are known to display very different aggregation properties. By extensive all-atom Monte Carlo simulations, we find that a variety of beta-sheet structures with dist

Background The aim of this study was to describe the Variable anatomy in the anastomosis between the umbilical arteries for better understanding of the physical characteristics of the umbilical Row velocity waveform (FVW). Methods. The arterial system of 67 placentas from pregnancies with normal umbilical FVW and resulting in a full-term AGA infant was visualized by angiography. The method allowed

This is a study of seven men that have suffered from a cruel punishment. The punishment involved getting their ear/ears cut off, prison with more torture and their families being deported from their homes to another town. My sample involved seven Iraqi men who suffered from this punishment during Saddams regime, they got this punishment because they refused to fight against Iran and Kuwait. I wen
