INTRODUCTION The lipid composition of spermatozoa plays an important role for successful fertilization. PATIENTS AND METHODS In the present study, we analyzed the fatty acid (FA) composition of spermatozoa of normozoospermic, asthenozoospermic, oligozoospermic and oligoasthenozoospermic men. RESULTS Spermatozoa from asthenozoospermic (P<0.01),(More)
PURPOSE The aim of this study was to optimize and predict the most efficient magnetic resonance imaging (MRI) sequences; T1-weighted (T1W), T2-weighted (T2W), dynamic contrast-enhanced (DCE) T1W, diffusion-weighted imaging (DWI) apparent diffusion coefficient (ADC) mapping sequences and proton MR spectroscopy (H-MRS) for the detection of prostate cancer.

OBJECTIVES To evaluate the association of fetuin-A polymorphisms with calcium oxalate nephrolithiasis. Fetuin-A is a circulating calcium-regulatory glycoprotein that inhibits extraosseous calcification. METHODS Fetuin-A c.742C > T and c.766C > G polymorphisms were investigated in 103 patients with calcium oxalate nephrolithiasis and 73 age- and(More)
OBJECTIVE To understand the utility of Diffusion-weighted MR imaging (DWI) in the diagnosis of acute pancreatitis. CONCLUSION DWI can analyse the major manifestations of acute pancreatitis without any contrast agent use and may replace Abdominal CT and routine Pancreas MRI as a primary investigation tool for acute pancreatitis.
In the diagnosis of traumatic and nontraumatic emergencies, computed tomography (CT) is the most frequently performed procedure. The aims of this study were to find out whether CT report results can be used as a reliable tool for the diagnosis and management of patients at an emergency department and to evaluate the appropriateness of the selection criteria(More)
PURPOSE We aimed to evaluate the role of kidney injury molecule-1 (KIM-1) in determining the intervals between shockwave lithotripsy (SWL) sessions. PATIENTS AND METHODS This was a prospective, controlled study. It included 40 patients with unilateral kidney stones and 40 healthy persons of a similar age group as controls. The patients' midflow urine(More)
PURPOSE Our aim was to evaluate the efficacy of Proton-MR Spectroscopy for the differentiation of cranial masses from non-neoplastic brain disorders. MATERIAL AND METHOD 33 patients with intracranial mass lesions, 29 patients with non-neoplastic brain lesions: Ischemic-demyelinating-metabolic-benign cystic mass group; As a whole 62 patients: 30 males and(More)
BACKGROUND Our aim was to evaluate the efficacy of Diffusion-Weighted Imaging (DWI) and Apparent Diffusion Coefficient (ADC) mapping with different b-factors in visualisation of meniscal tears. MATERIAL/METHODS Seventy-four patients; 30 males and 44 females, 37 left and 37 right knees with meniscal tears were involved in this study. Eleven of them were(More)
