BACKGROUND Women make up half of the world's population, and comprise 20% of the world's one billion smokers. The aim of this study was to assess the prevalence of smoking among female medical students in comparison to female non-medical students, and to assess the importance of medical education and knowledge in decreasing the prevalence of smoking among(More)
We have previously shown that pentoxifylline (PTX) protects from vascular complications associated with insulin resistance (IR). Here, we investigated the protective effect of PTX against cardiac ischemia and dysfunction following experimental angina in IR. IR, along with its accompanying cardiac dysfunction, was induced in rats by a high-fructose (10% in(More)
The objective of this study was to determine the differences between neonatologists and pediatric cardiologists with regards to the initial assessment of neonatal heart murmur and to evaluate the role of echocardiography in this group of patients. During a period of 1 year, all neonates with heart murmur seen in pediatric cardiology consultation from(More)
BACKGROUND AND OBJECTIVES Initial experience with transcatheter closure of patent ductus arteriosus (PDA) using detachable coils and Amplatzer duct occluder devices is reported. We evaluated the outcome, complications, and influence of the learning curve, and also assessed the need of surgical backup for such interventional procedures. METHODS From(More)
INTRODUCTION AND OBJECTIVE Pentoxifylline is a well-tolerated drug used in treatment of vascular insufficiency. We previously showed that pentoxifylline protects from impairment in vascular reactivity in cases of metabolic syndrome. The aim of this study was to investigate the protective effect of pentoxifylline against hypertension in metabolic syndrome(More)
This study investigated the effect of aldose reductase (AR) inhibitors on hypertension in diabetes. Diabetes was induced with streptozotocin, while AR inhibitors zopolrestat and ferulic acid were administered at 2 weeks after streptozotocin treatment and for 6 weeks afterwards. Then, blood pressure (BP) and serum level of glucose were determined.(More)
The aim of the present study is to investigate the effect and potential mechanism of action of 6-gingerol on alterations of vascular reactivity in the isolated aorta from diabetic rats. Male Wistar rats were divided into two experimental groups, control and diabetics. Diabetes was induced by a single intraperitoneal injection of streptozotocin (50 mg(More)
Adult male albino rats were treated orally with methoxychlor at doses of 0, 50, 100 or 200 mg/kg/day for 15 consecutive days. Testicular weight, sperm count and motility were significantly decreased. Methoxychlor at doses of 100 and 200 mg/kg significantly inhibited α-glucosidase activity, while plasma testosterone was significantly decrease by the three(More)
The aim of the present study was to investigate the effect and possible mechanism of action of zingerone, the main constituent of ginger, on vascular reactivity in isolated aorta from diabetic rats. The results show that incubation of aortae with zingerone alleviates the exaggerated vasoconstriction of diabetic aortae to phenylephrine, as well as the(More)
The aim of the current study was to evaluate the possible protective effect of allopurinol (Allo) on experimentally induced insulin resistance (IR) and vascular complications. Rats were divided into four groups: control, IR, allopurinol-treated IR (IR-Allo), and allopurinol-treated control (Allo). IR was induced by adding fructose and high fat, high salt(More)
