Cardiovascular diseases are the main reason of high mortality among hemodialysis patients. Decreased serum selenium levels may have a role in accelerated atherosclerosis in this patient group. The hypothesis of this study was to show a correlation between decreased serum selenium levels and coronary flow reserve as an indicator of endothelial dysfunction(More)
Cardiovascular disease (CVD) is the main cause of mortality in hemodialysis (HD) patients. Epicardial fat tissue (EFT) is a new risk factor in CVD. The aim of this study was to evaluate the association between EFT and coronary artery flow reserve (CFR), which is an early indicator of endothelial dysfunction in coronary vessels of HD patients. We performed a(More)
OBJECTIVES Accelerated atherosclerosis is the major cause of mortality in patients on chronic maintenance hemodialysis (HD). Epicardial fat tissue (EFT) is a new risk factor in cardiovascular disease (CVD). The aim of this study was to evaluate the relation between plasma coenzyme Q10 levels (Co-Q10) which is a potent physiologic antioxidant and EFT(More)
BACKGROUND Regional lymph node (LN) involvement in colorectal cancer (CRC) identifies the stage and the subset of patients who would benefit from adjuvant chemotherapy. We performed a retrospective analysis to determine if the number of recovered LNs was associated with long-term outcome in patients operated on for stage II and III CRC. PATIENTS AND(More)
BACKGROUND Cyclosporine (CsA)-associated nephrotoxicity is a long-term complication in transplant patients. Chronic CsA nephrotoxicity is associated with renal fibrosis and hyaline arteriolopathy. The aim of this study was to investigate the effect of spironolactone on functional and structural alterations as well as on platelet-derived growth factor B(More)
BACKGROUND/AIMS Contrast-induced nephropathy (CIN) remains a leading cause of iatrogenic acute renal failure. Terlipressin, a long-acting analog of vasopressin, may improve renal function. This study aimed to investigate the possible protective effect of terlipressin against the development of experimental CIN in rats. METHODS Wistar albino rats (n = 32)(More)
BACKGROUND Chronic cyclosporine (CsA) nephrotoxicity is associated with renal fibrosis and hyaline arteriolopathy. Fibrogenic cytokines, such as transforming growth factor-beta (TGF-beta) and vascular endothelial growth factor (VEGF), play a pivotal role in CsA nephrotoxicity. Previous studies have demonstrated the possible role of leukotrienes (LT) in(More)
OBJECTIVE The aim of the present study was to asses the accuracy of prediction equations in elderly patients with advanced renal disease (ARD). PATIENTS AND METHODS Twenty-three elderly patients (>60 years) with chronic kidney disease (CKD) stages 3-5 underwent technetium-99 m-diethylenetriaminepentaacetic acid (Tc-99m-DTPA) radionuclide measurement of(More)
BACKGROUND Renal vasoconstriction, activated by the renin-angiotensin system, plays a pivotal role in the pathogenesis of contrast-induced nephropathy (CIN). The purpose of this study was to evaluate the effect of aliskiren, a direct renin inhibitor, for the prophylaxis of experimental CIN in the rat. METHODS Thirty-two Wistar albino rats were divided(More)
Accelerated atherosclerosis is the major cause of mortality in patients on chronic hemodialysis (HD). The aim of this study was to evaluate the relation between coenzyme Q10 (CoQ10) levels and coronary flow reserve (CFR) in HD patients as an indicator of atherosclerosis. Seventy-one chronic HD patients and 65 age- and sex-matched healthy individuals were(More)
