OBJECTIVES To determine the serum and tissue levels of markers of impaired oxidative metabolism and correlate these levels with the histopathology and Alvarado score of acute appendicitis patients. METHOD Sixty-five acute appendicitis patients (mean age, 31.4±12.06 years; male/female, 30/35) and 30 healthy control subjects were studied. The Alvarado score was recorded. Serum samples were obta...

OBJECTIVES We tested a model in which Helicobacter pylori seropositivity (Hps) predicted iron status, which in turn acted as a predictor for markers of 1-C metabolism that were then allowed to predict antioxidant status. METHODS National Health and Nutrition Examination Surveys (NHANES 1999-2000) cross-sectional data among adults aged 20-85 y were analyzed (n = 3,055). Markers of Hps, iron st...

BACKGROUND/AIMS In this study we aim to evaluate the relationship of advanced oxidation protein products (AOPP), total thiol, total antioxidant status (TAS), total oxidant status (TOS) levels and oxidative stress index (OSI) in patients with nonalcoholic steatohepatitis (NASH). MATERIALS AND METHODS A total of 28 patients with NASH and 19 age-and-gender-matched healthy subjects were enrolled ...

BACKGROUND Decreasing or eliminating animal products from the diet decreases the intake of some essential nutrients, such as vitamin B(12), which may lead to hyperhomocysteinemia. We investigated vitamin B(12)-dependent metabolism and oxidative stress in groups with various or no intake of meat or animal products. METHODS We investigated 44 high meat eaters, 19 low meat eaters, 34 lacto-ovo/l...

In our study, we aimed to investigate ischemia modified albumin (IMA) as an oxidative stress marker, as well as other oxidant and antioxidant markers that have not been evaluated in children with celiac disease. A total of 37 pediatric patients who were diagnosed with celiac disease (CD) and 29 healthy children were enrolled in this prospective study. We evaluated the IMA, total oxidant status,...

OBJECTIVES The objective of the present study was to investigate the lipid and the antioxidant regulatory potential of a multigrain diet in laboratory animals with reference to lipid profiles, tissue lipid peroxidation and antioxidant status. METHODS Two types of diets, with or without addition of cholesterol, were used in the study - a commercial diet and a formulated multigrain diet (with S...

BACKGROUND/AIMS Helicobacter pylori infection has been suggested to be associated with atherosclerosis. The issue is still controversial. It is well known that abnormal lipid profile and oxidative stress are related to atherosclerosis and the measurement of carotid intima-media thickness. The aim of this study was to investigate carotid intima-media thickness and oxidative stress along with lip...
