900 MHz electromagnetic field exposure affects qualitative and quantitative features of hippocampal pyramidal cells in the adult female rat

The effects of electromagnetic fields (EMFs) emitted by mobile phones on humans hold special interest due to their use in close proximity to the brain. The current study investigated the number of pyramidal cells in the cornu ammonis (CA) of the 16-week-old female rat hippocampus following postnatal exposure to a 900 megahertz (MHz) EMF. In this study were three groups of 6 rats: control (Cont), sham exposed (Sham), and EMF exposed (EMF). EMF group rats were exposed to 900 MHz EMF (1 h/day for 28 days) in an exposure tube. Sham group was placed in the exposure tube but not exposed to EMF (1 h/day for 28 days). Cont group was not placed into the exposure tube nor were they exposed to EMF during the study period. In EMF group rats, the specific energy absorption rate (SAR) varied between 0.016 (whole body) and 2 W/kg (locally in the head). All of the rats were sacrificed at the end of the experiment and the number of pyramidal cells in the CA was estimated using the optical firactionator technique. Histopathological evaluations were made on sections of the CA region of the hippocampus. Results showed that postnatal EMF exposure caused a significant decrease of the pyramidal cell number in the CA of the EMF group (P < 0.05). Additionally, cell loss can be seen in the CA region of EMF group even at qualitative observation. These results may encourage researchers to evaluate the chronic effects of 900 MHz EMF on teenagers' brains. (C) 2009 Elsevier B.V. All rights reserved

Assessment of pulmonary functions and anthropometric measurements in women with polycystic ovary syndrome

Objectives. The aims of this study were to compare pulmonary function tests of patients with polycystic ovary syndrome (PCOS) versus healthy women, and to investigate correlations between pulmonary function tests and anthropometric measurements of them

Effects of balneotherapy with exercise in patients with low back pain

Low back pain (LBP) is an important clinical, social, and public health problem. Balneotherapy is a type of therapy by hot or warm waters containing minerals. The aim of this study was to investigate the effects of balneotherapy with exercise on pulmonary functions, aerobic exercise capacity, resting metabolic rate, body fat %, psychosocial condition and its efficiency on therapy in patients with LBP. Balneotherapy and exercise program were applied to group 1 (14 female, 9 male). Only an exercise program was applied to group 2 (13 female, 8 male). The measurements of maximal oxygen consumption, resting metabolic rate, pulmonary function tests, body fat %, Oswestry disability index, visual analog scale, quality of life measure, symptom checklist-90-revised, the hospital anxiety and depression scale, spine joint mobility tests from all participants were performed before and after the treatment. An improvement was found in pulmonary function test (maximal volunteer ventilation), aerobic exercise capacity, pain and disability scores, spine mobility (extension distance), quality of life, and all psychiatric symptoms (except anxiety) in group 1 following therapy period. Also some improvements were observed in body fat percentage, pulmonary function tests (forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow at 25% to 75% vital capacity and peak expiratory flow), and other spine joint mobility tests before and after therapy in group 1, though they were not statistically significant. Balneotherapy with exercise could be alternative therapy methods in patients with LBP

Association analyses of depression, anxiety, and physical fitness parameters in Turkish obese adults

Objective: This study aims to investigate the associations among depression, anxiety, aerobic exercise capacity, body fat percentage, sum of skinfolds, abdomen circumference, and waist to hip ratio on the basis of body mass index (BMI) in adults. Methods: The subjects of the study were 60 obese participants (30 women, 30 men) with BMIs over 30 kg/m(2) and 60 healthy controls (30 women, 30 men) with BMIs of 18-25 kg/m(2). Body fat percentage was calculated from the skinfold thicknesses using the formula. Body circumference measurements were performed using a tape measure. Maximal aerobic capacity (VO(2)max) was determined by Astrand submaximal exercise protocol. Two self-reported questionnaires, Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI), were administered to all participants. Results: BMI, body fat percentage, sum of skinfolds, abdomen circumference, and waist to hip ratio were found to be higher in obese groups as compared to the controls, while VO(2)max (ml/kg/min) values were lower in both genders. In males, BAI scores and mild-level anxiety percentage values were higher in the obese group than in the control group. There was no significant difference for BDI scores and levels between the obese and control groups in both genders. There was also no significant difference in BAI scores and levels between the obese and control groups in women. Conclusion: The fact that physical fitness being found poor in obese shows the existence of a condition that might constitute an increased tendency for obesity-related disorders. In addition, it was suggested that, in Turkey, attitudes toward obesity change depending on gender
