OBJECTIVES To examine the relationship between platelets (PLT) and platelets indices such as mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) as noninvasive biomarkers with testicular artery blood flow and fertility. METHODS Fifty-seven healthy and fertile men with normal semen values and 52 patients with abnormal semen values were included in the study. T...

To determine the effects of verapamil on left ventricular (LV) systolic function and diastolic filling in patients with coronary artery disease (CAD), we performed gated radionuclide angiography at rest and during exercise in 16 symptomatic patients before and during oral verapamil therapy (480 mg/day). Twelve patients were also studied during oral propranolol (160--320 mg/day). LV ejection fra...

Surgical ventricular restoration (SVR) was designed to treat patients with aneurysms or large akinetic walls and dilated ventricles. Yet, crucial aspects essential to the efficacy of this procedure like optimal shape and size of the left ventricle (LV) are still debatable. The objective of this study is to quantify the efficacy of SVR based on LV regional shape in terms of curvedness, wall stre...

BACKGROUND We investigated the changes in the values of carotid intima-media thickness (IMT) and Doppler index measurements in the autosomal dominant polycystic kidney disease (ADPKD), peritoneal dialysis (PD), and hemodialysis (HD) patients. MATERIAL AND METHODS Twenty outpatients on HD (mean age 46.1 ± 16.4), 27 outpatients on PD (mean age 45 ± 12.4), and 26 normotensive outpatients with AD...

The aim of the present study was to investigate the clinical value of low‑dose aspirin in combination with Tiao Jing Cu Yun pills in patients with polycystic ovary syndrome (PCOS) by measuring follicular peripheral blood flow parameters and the clinical efficacy. The study involved 78 infertile females with PCOS who were randomly divided into experimental (n=38) and control (n=40) groups. The s...

Ejection Fraction (EF) has attained the recognition as indicator of global ventricular performance. Remarkably, precise historical origins promoting the apparent importance of EF are scant. During early utilization EF has been declared a gold standard for the evaluation of the heart as a pump. In contrast, during the last two decades, clinicians have developed a measure of doubt in the universa...

BACKGROUND To date, there has been little agreement on the use of ultrasonographic parameters in predicting the long-term outcome after transplantation. This study evaluates whether ultrasonography of the graft performed in the early stage after transplantation is a valuable predictor for long-term-outcome. OBJECTIVES The aim of this study was to evaluate the association of ultrasonographic p...

BACKGROUND Responses of cerebral blood flow to the postural unloading maneuver in aortic stenosis (AS) have not been described so far. Our aim was to assess effects of orthostatic stress test on changes of carotid and vertebral artery blood flow and transaortic gradients. METHODS From consecutive 101 AS patients we selected 50 patients with severe isolated AS. Maximal and mean transaortic pre...

BACKGROUND To analyze the diagnostic value of color Doppler imaging (CDI) of blood flow in the retrobulbar vessels of eyes with primary open-angle glaucoma (POAG). METHODS Pertinent publications were retrieved from the Cochrane Central Register of Controlled Trials, PubMed and the ISI Web of Knowledge up to October 2012. Changes in peak systolic velocity (PSV), end diastolic velocity (EDV) an...
