offerosclerosis and osteoporosis are major causes of morbidity and mortality in postmenopausal women and have been suggested to be associated. No study has examined whether progression of atherosclerotic calcification is associated with bone loss. In the present study, we examined progression of aortic calcification, diagnosed by radiographic detection of calcified deposits in the abdominal aor...

PURPOSE The present study examined how age, bodyweight, body fat, regular exercise and some endocrine factors are associated with osteoporosis, spine bone mineral density (Sbmd) and femoral neck bone mineral density (Fnbmd) in Singaporean men. METHODS Body composition and bone scans of lumbar spine at L2-L4 and hip were carried out with duel-energy X-ray absorptiometry (DXA). Anthropometric p...

BACKGROUND Conflicting results exist about the short-and long-term effects of breastfeeding on bone mineral content (BMC) and bone mineral density (BMD). We conducted a systematic review to assess the relationship between method of infant feeding and bone mass in children, adolescents and adults. METHODS The literature review was concluded in September 2014 in MEDLINE, Web of Science and LILA...

The effect of subclinical hyperthyroidism on bone mineral density is controversial and could be significant in patients with differentiated thyroid carcinoma who receive suppressive doses of levothyroxine (LT4). To ascertain whether prolonged treatment with LT4 to suppress thyrotropin had a deleterious effect on bone mineral density and/or calcium metabolism in patients thyroidectomized for dif...

Lutein (L) and zeaxanthin (Z) status can be quantified by measuring their concentrations both in serum and, non-invasively, in retinal tissue. This has resulted in a unique ability to assess their role in a number of tissues ranging from cardiovascular to central nervous system tissue. Recent reports using animal models have suggested yet another role, a developmental increase in bone mass. To ...

background: jaw bone quality plays an essential role in treatment planning and prognosis of dental implants. regarding several available methods for bone density measurements, they are not routinely used before implant surgery due to hard accessibility. objective: an in vitro investigation of correlation between average gray scale in direct digital radiographs and hounsfield units in ct-scan pr...

background: the singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (ap) radiograph. the purpose of this study was to compare between singh index and bone mineral density measurement using dual energy x-ray absorptiomet...

background: the extent of bone minerals density (bmd) gained during childhood is good index for bmd in adulthood. recent studies imply that exercise increases bmd however, there are rare studies about the best ages in which exercise gives the highest effect on children’s bmd. this study was carried out with the aim of comparing the extent of exercise effect on various ages on bmd of boys of ila...

BACKGROUND Osteoporosis has become a major public health issue. Among various factors affected bone health, not only dietary calcium and phosphorus intakes, but also the dietary calcium/phosphorus ratio could relate to bone health. Therefore, we evaluated whether dietary calcium and phosphorus intakes, and dietary calcium/phosphorus ratio are associated with bone mass in Korean adults ≥ 20 year...

This paper reviews the growth and development of skeletal mass in youth and the effects of physical activity upon the bone mass in young people. The different methods to measure the bone mass are described such as anthropometrics, radiographics, dual energy X-ray absorptiometry, quantitative computed tomography, and ultrasound. Tho different mechanisms are important for the formation and plasti...
