An Optical Coherence Tomography Study that Supports the Neurovascular Basis of Schizophrenia Disease.

Objectives: Spectral domain optical coherence tomography (SD-OCT) is a non--penetrating, quick, and practical device which enables measurement of the chorioretinal layers. In this study, our purpose was to investigate the retinal nerve fiber layer (RNFL) and choroidal thickness in schizophrenia patients, using SD-OCT, and compare the -findings with those of the control group.

Methods: For the study, 44 patients with a diagnosis of schizophrenia, and 41 age- and gender- matched healthy controls were enrolled.

Serum selenium and plasma malondialdehyde levels and antioxidant enzyme activities in patients with obsessive-compulsive disorder.

There is mounting evidence indicating that reactive free radical species are involved in initiation and development of many different forms of human pathologies including psychiatric disorders. In the present study, we aimed to determine whether serum selenium (Se), antioxidant enzyme (glutathione peroxidase, GSH-Px, superoxide dismutase, SOD, and catalase, CAT) activities, and plasma malondialdehyde (MDA) levels, a product of lipid peroxidation, were associated with obsessive-compulsive disorder (OCD). The participants were 28 patients with OCD that were drug-free at least for a month and a control group (n=28) of healthy subjects, matched with respect to age and sex.

Examination of free radical metabolism and antioxidant defence system elements in patients with obsessive-compulsive disorder.

Free radicals and oxidative stress are involved in the pathogenesis of various diseases. Malondialdehyde (MDA) is a natural product of lipid peroxidation in all mammalian cells. Vitamins C and E are nonenzymatic antioxidant structures.

The prevalence of eating disorders among university students and the relationship with some individual characteristics.

Objective: The purpose of this study was to determine the prevalence of eating disorders (EDs) among university students in a rural area of Turkey and to compare groups based on the sociodemographic data, history of child abuse and neglect, family roles and self-esteem with a normal control group regarding EDs.
