fracture. several chronic medical conditions, medications, and life style factors affect bone mineral accrual. this study aims to evaluate the bone mineral densities and hip axis lengths in the local population. materials and methods: 336 normal bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (bmds) by means of dual x-ray absorptiometry (dxa). results:...

Recent developments in dual-energy X-ray CT have shown a number of benefits over standard CT for object separation, contrast enhancement, artifact reduction, and material composition assessment. As with traditional CT, model-based iterative approaches to reconstruction offer the opportunity to reduce noise and artifacts in dual energy reconstructions. However, previous approaches to model-based...

The objective of this cross-sectional study was to compare the body composition and fat distribution measured by dual energy X-ray absorptiometry (DPX, Lunar) in different age decades of age-matched Danish and Italian women. The subjects comprised 133 healthy Italian women (age 20-60 years) age-matched to a representative sub-sample of healthy Danish women (n=375). Total and abdominal body fat ...

background one of the most important causes of mortality in developed and developing countries is coronary artery disease. coronary artery disease (cad) may develop by deposition of lipid, fibrous or calcified debris on the surface of the coronary artery lumen. fibrous plaque and calcified plaque may cause substantial stenosis of coronary arteries leading to ischemia of heart muscle while lipid...

BACKGROUND We tested the hypothesis that ad libitum food intake shows corrective responses over periods of 1-5 d. DESIGN This was a prospective study of food intake in women. METHODS Two methods, a weighed food intake and a measured food intake, were used to determine daily nutrient intake during 2 wk in 20 women. Energy expenditure with the use of doubly labeled water was done contemporane...

Animal ecology is shaped by energy costs, yet it is difficult to measure fine-scale energy expenditure in the wild. Because metabolism is often closely correlated with mechanical work, accelerometers have the potential to provide detailed information on energy expenditure of wild animals over fine temporal scales. Nonetheless, accelerometry needs to be validated on wild animals, especially acro...
