Rosiglitazone is an anti-diabetic agent that raised a major controversy over its cardiovascular adverse effects. There is in vivo evidence that Rosiglitazone promotes cardiac hypertrophy by PPAR -γ-independent mechanisms. However, whether Rosiglitazone directly alters hypertrophic growth in cardiac cells is unknown. Chromatin remodeling by histone post-translational modifications has emerged as critical for many cardiomyopathies. Based on these observations, this study was initiated to investigate the cardiac hypertrophic effect of Rosiglitazone in a cellular model of primary neonatal rat cardiomyocytes (NRCM)...

BACKGROUND: Recently, depression has been envisioned as more than an alteration in neurotransmitters centered around receptor signaling pathways. Consequently, the precise mechanisms of selective serotonin reuptake inhibitor (SSRI) antidepressant drugs such as fluoxetine are being revisited. Zinc is a trace element that has been long implicated in the psychopathology and therapy of depression. Zinc has been found to be sequestered and dispensed during stress and inflammation through a family of proteins called metallothioneins (MTs)...

Many researches document long-term RNA persistence in a variety of tissues and its applicability in estimating the postmortem interval (PMI). Skin-specific mRNA marker, late cornified envelope 1C (LCE1C), was used to identified skin samples. Before using the LCE1C in criminal casework, its persistence and applicability for estimating PMI in different temperatures were tested. Twelve skin samples were collected from 6 patients, and 6 samples were kept at 24°C and others were kept at 40°C for 5 days. The expression levels of LCE1C mRNA are serially detected and quantified using real-time polymerase chain reaction...

Introduction: The interactions between biomacromolecules such as serum albumin (SA) and various drugs have attracted increasing research attention in recent years. However, the study of SA with those drugs that have relatively high hydrophilicity and a lower affinity for SA could be a challenging issue. At the present study, the interaction of bovine SA (BSA) with neomycin as a hydrophilic drug has been investigated using surface plasmon resonance (SPR) and molecular docking methods. Methods: BSA was immobilized on the carboxymethyl dextran hydrogel sensor chip after activation of carboxylic groups through NHS/EDC and, then, the neomycin interaction with BSA at different concentrations (1-128 µM) was investigated...

MicroRNAs (miRNAs) are short non-coding RNAs which target mRNAs by binding to them and regulating their expression. Involvement of miRNAs has been discovered in many diseases, so it is fruitful to investigate the miRNAs and their targets to develop new therapeutic ways by designing anti-miRNA oligonucleotides. There are various computational methods to predict the target genes, however, their precisions are not good enough. In this paper, we apply a two-step approach to refine the results of sequence-based prediction algorithms...

A critical bottleneck limiting the performance of rechargeable zinc-air batteries lies in the inefficient bifunctional electrocatalysts for the oxygen reduction and evolution reactions at the air electrodes. Hybridizing transition-metal oxides with functional graphene materials has shown great advantages due to their catalytic synergism. However, both the mediocre catalytic activity of metal oxides and the restricted 2D mass/charge transfer of graphene render these hybrid catalysts inefficient. Here, an effective strategy combining anion substitution, defect engineering, and the dopant effect to address the above two critical issues is shown...
