This study investigated the effects of repeatedly administration of an aqueous fraction of Paullinia cupana Kunth, Sapindaceae (guaraná) seeds (8 mg/ kg) on rats submitted to the elevated T-maze, model of generalized anxiety and panic disorders. The selective serotonin reuptake inhibitor paroxetine (3 mg/kg), was used as a positive control. To evaluate possible neurotransmissions involvement, i...

BACKGROUND Atrial fibrillation (AF) is the most common cardiac arrhythmia with a population prevalence of about 1%. Natriuretic peptide level is elevated in patients with AF with diastolic dysfunction even with a normal left ventricular (LV) ejection fraction. The N-terminal pro-brain natriuretic peptide (NT-proBNP) level and Doppler echocardiographic parameters for diastolic function have show...

BACKGROUND In heart failure and reduced ejection fraction, the prognostic role of heart rate (HR) in atrial fibrillation (AF) is unknown and the effectiveness of β-blockers has recently been questioned in AF. METHODS AND RESULTS A total of 18 858 patients with heart failure and reduced ejection fraction registered with Swedish Heart Failure Registry were included in this study: patients with ...

OBJECTIVE The use of drugs with herbal origin is increasing for treatment of gastrointestinal (GI) disorders. Rosa damascena (R. damascena) is a well-known plant suggested to have beneficial effect on GI system. In this study, the effect of aqueous fraction of R. damascena on the contractions of isolated guinea pig ileum was investigated. MATERIALS AND METHODS Aqueous fraction of plant was ob...

Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...

Introduction: Nowadays, there is special interest in finding a new contraceptive drug with high safety and fewer side effects. Investigations have shown that dill (Anethum graveolens L.) can be used either as a menstrual cycle regulator or contraceptive. Since cell surface terminal sugars have crucial roles in oocyte maturation, fertilization and implantation, in this study we investigated the ...

Objective: The present study was undertaken to assess the effect of Momordica charantia fruits on diabetes mellitus and its related complications. Methods: Crude powder, aqueous, 95% and 50% ethanol extract of Momordica charantia fruits were administered to normal rats post sucrose load and streptozotocin-induced (STZ-induced) diabetic rats in single-dose study. The aqueous extract was further ...

OBJECTIVES we investigated whether cardiac sympathetic nervous system (SNS) activity measured by iodine-123 meta-iodobenzylguanidine ((123)I-mIBG) imaging would be associated with both the occurrence of heart failure (HF) and the transit to permanent atrial fibrillation (AF) in patients with paroxysmal AF. BACKGROUND atrial fibrillation occurs suddenly and transiently and can persist, and res...

Catheter ablation is an important treatment modality for management of Atrial Fibrillation (AF). AF a responsible factor in the pathophysiology Heart Failure with Preserved Ejection Fraction (HFpEF). However, relationship between and Right Ventricular (RV) dysfunction has not been completely distinguished.

BACKGROUND The increasing prevalence of atrial fibrillation (AF) represents a public health issue. Identifying new predictors of AF is therefore necessary to plan preventive strategies. We investigated whether left ventricular (LV) systolic dysfunction by global longitudinal strain (GLS), a predictor of cardiovascular events, may predict new-onset AF in a population setting. METHODS AND RESUL...
