background: the aim was to investigate the relationships among lean mass (lm), fat mass (fm), and bone mineral density (bmd) in women stratified by body mass index (bmi) (bmi – normal-weight, overweight, obese) and to determine threshold at which body fat assumes negative relationship with bmd. methods: this was a cross-sectional study in 471 healthy caucasian women, aged 18-67 years. bmd, lm, ...

conclusions the findings indicated that older women with low bmi were at higher risk of low bone mass. body weight, bmi and aging may be important predictors of bmd, but they are not the only factors affecting bone loss. therefore, it is recommended to assess other risk factors with a larger number of patients. results the mean bmd of women older than 50 years compared to those younger than 50 ...

The regulation of bone metabolism mediated by leptin is a complex process that is not clearly understood. Recent studies suggest that CART (cocaine-amphetamine related transcript) is a significant neuronal co-factor when combined with leptin. CART deficiency is thought to result in low trabecular bone mass, but since leptin exerts contrasting effects on trabecular and cortical bone it is possib...

Bone homeostasis is maintained through a delicate balance between osteoblastic bone formation and osteoclastic bone resorption. Bone loss may be due to decreased osteoblastic bone formation and increased osteoclastic bone resorption. Osteoporosis is induced with its accompanying decrease in bone mass. Nutrition and functional food factors may play a role in the prevention of bone loss. This is ...

To examine the effects of short high-intensity interval training (HIIT) on body composition, physical performance and plasma lipids in overweight/obese compared to normal-weight young men. Nine overweight/obese and nine normal-weight men (control group) aged 17 to 20 years underwent a HIIT programme three times per week for eight weeks. Body composition, indices of aerobic [maximal aerobic velo...

background: corticosteroids (cs) are used widely for their anti-inflammatory and immunosuppressive properties. they have the potential to cause dramatic improvement as well as produce equally dramatic adverse effects. the clinical misuse like over prescription of the drug should be avoided. long-term administration may cause many adverse effects leading to impaired oral health. oral health is u...
