Chronic morphine addiction may trigger functional changes in the mesolimbic dopamine system, which is believed to be the neurobiological substrate of opiate addiction. Brain derived neurotrophic factor (BDNF) has been implicated in addiction-related pathology in animal studies. Our previous studies have shown that RACK1 is involved in morphine reward in(More)
AIMS To investigate the influence of three single nucleotide polymorphisms (SNPs) in exon 12 (C1236T), exon 21 (G2677T/A) and exon 26 (C3435T) of MDR1 gene on the absorption of valacyclovir after a single oral administration in the Chinese Han ethnic population. METHODS Two hundred healthy Chinese subjects were genotyped for the SNPs of C1236T, G2677T/A(More)
Cajanus cajan (L.) is a traditional Chinese herb medicine which contains a lot of potential active components. In the present study, we identified the effects of the stilbenes containing extract-fraction from C. cajan L. (sECC) on Abeta(25-35)-induced cognitive deficits, oxidative stress and cholinergic dysfunction in mice. Mice were treated with sECC (100(More)
AIMS The clinical implementation of His-bundle pacing (HBP) has been limited by concern over higher capture thresholds (CTs) and lower R-wave amplitudes (RWAs), when compared with right ventricular (RV) pacing. The aim of this study was to assess the optimal pacing configuration for HBP lead when incorporated with cardiac resynchronization(More)
To examine microRNA-133a (miR-133a) endogenous expression in cardiomyocytes after ischemia-reperfusion (I/R) injury and study the effects of miR-133a overexpression on I/R injury-induced cardiomyocyte apoptosis. Dual-Luciferase Reporter Assay detected dynamic expression of miR-133a. In an in vitro hypoxia-reoxygenation (HR) injury model and an in vivo rat(More)
We report a 57-year-old male patient with dilated cardiomyopathy, NYHA function class III and complete left bundle branch block (CLBBB) who received cardiac resynchronization therapy using His-bundle pacing (HBP) when a left-ventricular lead could not be placed. In 10 months' follow up, his symptoms resolved rapidly, his QRS, left ventricular and left(More)
Atrial fibrillation (AF) is the most common arrhythmia requiring medical treatment and has been associated with enhanced atrial fibrosis and heart failure (HF). Relaxin (RLX), an antifibrosis and antiinflammatory peptide hormone, may be used to evaluate atrial fibrosis and is associated with HF occurrence in AF. We aimed to clarify the clinical significance(More)
BACKGROUND Clinical benefits from His bundle pacing (HBP) in heart failure patients with preserved and reduced left ventricular ejection fraction are still inconclusive. This study evaluated clinical outcomes of permanent HBP in atrial fibrillation patients with narrow QRS who underwent atrioventricular node ablation for heart failure symptoms despite rate(More)
The optimal pacing modality after atrioventricular junction (AVJ) ablation remains unclear. Herein, we describe the case of a heart failure patient who had AVJ ablation for chronic atrial fibrillation and received a cardiac resynchronization therapy defibrillator device. Because of the lack of clinical response to biventricular pacing, the device was(More)
