OBJECTIVE Osteoprotegerin (OPG) is a member of the tumor necrosis factor superfamily with pleiotropic effects on inflammation, endocrine function and the immune system. Reduced OPG levels are related to insulin resistance. We tested the hypothesis that serum levels of OPG may be associated with nonalcoholic fatty liver disease (NAFLD). MATERIAL AND(More)
Accurate assessment of the anti-growth effects of chemotherapeutics is immensely importance in cancer research with regard to drug discovery and toxicological safety. A number of in vitro cytotoxicity assays are used for these purposes. However, there is the possibility for different results in the assessments because the way they measure the viability of(More)
OBJECTIVES Levels of soluble receptor for advanced glycation endproducts (sRAGE) have been linked to several components of the metabolic syndrome. We tested the hypothesis that plasma levels of sRAGE may be associated with non-alcoholic fatty liver disease. DESIGN AND METHODS We enrolled subjects with definite nonalcoholic steatohepatitis (NASH, n=40),(More)
OBJECTIVE Obesity and obstructive sleep apnea (OSA) and systemic inflammation may interact through biochemical pathways. Neopterin (NP) is a monocyte/macrophage activation marker produced by macrophages in response to interferon-gamma secreted by activated T-lymphocytes. This study examines the association between NP, obesity and OSA. PATIENTS AND METHODS(More)
BACKGROUND Apoptosis is thought to be induced by chemotherapy in cancer patients. Therefore, the measurement of its amplitude may be a useful tool to predict the effectiveness of cancer treatment sooner than conventional methods do. PATIENTS AND METHODS In the study presented, apoptosis was assessed with an ELISA-based assay in which caspase-cleaved(More)
BACKGROUND Caspase-cleaved cytokeratin 18 (CK18-Asp396) is released from hepatocytes during apoptosis. Recent studies have indicated that serum levels of CK18-Asp396 could be a clinically useful biomarker of chronic liver disease. To shed more light on the rate of hepatocyte loss by apoptosis in chronic liver disease, serum levels of CK18-Asp396 were(More)
BACKGROUND Serum concentrations of fetuin A/α2HS-glycoprotein (AHSG) have been linked to human metabolic alterations and can serve as an indicator of liver cell function. We assayed serum levels of AHSG in patients with non-alcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, and examined their association with clinical,(More)
PURPOSE To determine whether 50 Hz extremely low frequency-magnetic fields (ELF-MF) affects apoptotic processes, oxidative damage, and reproductive characteristics such as sperm count and morphology in rat testes. MATERIALS AND METHODS Thirty male Sprague-Dawley rats were used in the present study, which were divided into three groups (sham group, n = 10,(More)
Fibrosarcoma is one of the fatal cancer types and there is still not satisfactory success in its treatment despite new drugs. Therefore, the search for a new compound has been going on. It is currently known that some palladium-based anti-cancer compounds seem to have powerful apoptosis-inducing effects in cancer cells. For this purpose, a(More)
OBJECTIVES Growing evidence has indicated the potential clinical usefulness of measuring different forms of cytokeratin 18 in patient sera (M30 antigen for apoptosis and M65 antigen for necrosis) for distinguishing different forms of cell death. Preliminary data have reported altered levels of cytokeratin 18 fragments in patients with acute coronary(More)
