objective(s) bone is a dynamic tissue that is continuously renewed throughout life by the process of bone remodeling. antioxidant system might be involved in the pathogenesis of bone loss, so the aim of this study was to evaluate the total antioxidant capacity (tac), vitamin c and vitamin e levels of plasma besides measuring enzymatic antioxidants, superoxide dismutase (sod), catalase (cat) and...

background: osteoporosis is a preventable and treatable disorder, reported with higher prevalence patients with ulcerative colitis but their relationship is controversial. osteoporosis in these patients may be attributes to corticosteroid use, malnutrition and reduced intake of calcium and vitamin d, lower levels of sex hormones, chronic inflammation and inflammatory cytokines. the aim of study...

introduction:there is considerable amount of controversy about the long term effects of multiparity and duration of breast-feeding on maternal bone mineral density after menopause. this study was conducted to determine whether multiple pregnancy and prolonged duration of breast-feeding are independent predictors of low bone mass in post-menopausal kurdish women. methods: in a retrospective stud...

background: the purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. patients and methods: this was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the all-...

OBJECTIVES To screen for low bone mineral density among young adult Saudi women using quantitative ultrasound (QUS) and exploring the high risk groups. Methods: A cross-sectional study was performed on 279, 20-36 years old female students and employees of Taibah University, Al Madinah Al Munawwarah, Kingdom of Saudi Arabia between January and May 2014. The study included bone status assessed us...

Low bone density is a growing concern in aging men with hemophilia and may result in high-morbidity fragility fractures. Using high-resolution peripheral quantitative computed tomography (HR-pQCT), we demonstrate low trabecular and cortical bone density contributing to lower volumetric bone mineral density (BMD) at both distal radius and tibia in patients with hemophilia compared with age- and ...

BACKGROUND To identify factors that predict low bone mineral density (BMD) in pediatric patients referred for dual-energy x-ray absorptiometry assessments. METHODS This is a retrospective cohort study of 304 children and adolescents referred for dual-energy x-ray absorptiometry assessments at a tertiary care center. Outcomes included risk factors which predicted a significant low bone density...

the present study investigates the effect of different exposure densities on third grade iranian junior high school (ijhs) students’ efl development and retention. it also attempts to explore whether there is any differential performance due to type of post-exposure assessment tasks (recognition vs. written production). performances of five groups of learners receiving equal amount of exposure ...
