With fully conclusive findings about the toxicity of carbon nanotubes (CNTs) still up in the air, research on biomedical applications of CNTs is pushing full steam ahead. Adding to the list of potential concerns, a recent nanotoxicology study by a U.S.-Chinese research team looked into the impact of carbon nanotubes on male reproductive health. The translocation and biodistribution of nanoparti...
هیدرازینیوم 5-آمینو تترازولات یکی از مواد منفجره مهم می باشد که از واکنش هیدرازین با 5-آمینوتترازول به وجود می آید. در این تحقیق، انرژی برهمکنش مولکول هیدرازین با هفت تاتومر مولکول 5- آمینوتترازول بر اساس روش های محاسباتی اختلالی وتابعی چگال محاسبه شده است. بدین منظور مولکول هیدرازین در 25 جهت گیری مختلف در اطراف تاتومرها قرار داده شده است. محاسبات به طور جداگانه در محیط های گازی وحلال شامل آب،...
Oxidation of 5-methylcytosine in DNA by ten-eleven translocation (Tet) family of enzymes has been demonstrated to play a significant role in epigenetic regulation in mammals. We found that Tet enzymes also possess the activity of catalyzing the formation of 5-hydroxymethylcytidine (5-hmrC) in RNA in vitro. In addition, the catalytic domains of all three Tet enzymes as well as full-length Tet3 c...
In this paper we describe a highly sensitive and selective liquid chromatographic method for the determination of 5-methoxyindoles (5-methoxyindole-3-acetic acid, 5-methoxytryptamine, 5-methoxytryptophol, and melatonin) using a post-column technique involving electrolytic demethylation followed by fluorescence derivatization with benzylamine. We separated these compounds within 30 min by revers...
Cytosine derivative dysregulations represent important epigenetic modifications whose impact on the clinical outcome in chronic lymphocytic leukemia (CLL) is incompletely understood. Hence, global levels of 5-methylcytosine (5-mCyt), 5-hydroxymethylcytosine (5-hmCyt), 5-carboxylcytosine (5-CaCyt) and 5-hydroxymethyluracil were tested in purified B cells from CLL patients (n = 55) and controls (...
