BACKGROUND Frequent use of Facebook and other social networks is thought to be associated with certain behavioral changes, and some authors have expressed concerns about its possible detrimental effect on mental health. In this work, we investigated the relationship between social networking and depression indicators in adolescent population. SUBJECTS AND(More)
CONTEXT Atypical antipsychotics (SGA) have the propensity to induce weight gain. OBJECTIVE The aim was to evaluate early changes in hormones involved in neuroendocrine regulations (serum cortisol, growth hormone and prolactin) and positive energy balance (serum insulin, leptin and ghrelin) during SGA treatment in normal-weight patients with schizophrenia(More)
INTRODUCTION AND HYPOTHESIS The majority of studies reporting decreased bone mineral density (BMD) in patients with unipolar depression neglected sex and age differences and menopause as the most important risk factor for osteoporosis. We presumed that physically healthy premenopausal women with unipolar depression have decreased BMD and altered bone cell(More)
Schizophrenia (SZ) is a neuroprogressive disorder presenting with biochemical, functional, and structural changes, which differ from early to late stages of the illness. We explored the differences in serum levels of soluble intercellular cell adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) between early and late stages(More)
OBJECTIVE In our study we have hypothesized that volume changes of amygdala, hippocampus, and prefrontal cortex are more pronounced in male posttraumatic stress disorder participants. MATERIAL AND METHODS We have conducted a study of 79 male participants who underwent MRI brain scanning. PTSD diagnosis was confirmed in 49 participants. After MRI was taken(More)
BACKGROUND Endometriosis is a complex disease that can result in substantial morbidity, including chronic pain, dysmenorrhea and dyspareunia. There are contradictory reports regarding the connection between acute and chronic stress and magnesium levels in body fluids. SUBJECTS AND METHODS A prospective study included 87 patients undergoing laparoscopy.(More)
BACKGROUND Sleep disorders are frequent symptoms described in psychiatric patients with major depression and schizophrenia. These patients also exhibit changes in sleep architecture measured by polysomnography (PSG) during sleep. The aim of the present study was to identify potential biomarkers to facilitate diagnosis based on PSG measurements. SUBJECTS(More)
Subjects and Methods: 30 patients with schizophrenia, 30 patients with major depression and 30 healthy control subjects were investigated in the present study. The mean age in the group with schizophrenia was 36.73 (SD 6.43), in the group of patients with depression 40.77 (SD 7.66), in the healthy controls group 34.40 (SD 5.70). The gender distribution was(More)
The aim of this study was to define all the areas of changes in expression of nuclear c-Fos protein (c-Fos), cytoplasmic somatostatin (SS) and neuropeptide Y (NPY) in rat brain during experimental ischemia. Using the immunohistochemical method, brain mapping (based on the atlas by Paxinos & Watson) of immunoreactivity for c-Fos, SS and NPY in 39 rats, was(More)
Recent studies have suggested that both high- and low-frequency repetitive transcranial magnetic stimulation (rTMS) have antidepressant effects in patients with major depression. We conducted an open study to assess the effects of slow rTMS on mood changes in patients with depression associated with Parkinson's disease (PD). Ten depressed patients with PD(More)
