OBJECTIVE To investigate the effect of acute resistance exercise on adipose tissue triacylglycerol lipase activity (TGLA) in lean and obese men. RESEARCH DESIGN AND METHODS Nine lean and eight obese men performed 30 min of circuit resistance exercise. Adipose tissue and blood were sampled during exercise for TGLA, metabolite, and hormone determinations.(More)
OBJECTIVE To evaluate the time course of leptin, adiponectin, and resting energy expenditure (REE) responses in overweight elderly males after acute resistance exercise protocols of various intensity configurations. RESEARCH DESIGN AND METHODS Forty inactive men (65-82 years) were randomly assigned to one of four groups (n = 10/group): control,(More)

Strontium ranelate (SR) is a novel anti-osteoporotic agent approved for the treatment of postmenopausal osteoporosis. SR appears to reduce bone resorption by decreasing osteoclast differentiation and activity, and to stimulate bone formation by increasing replication of pre-osteoblast cells, leading to increased matrix synthesis. The effect of SR on bone(More)

There are numerous studies presenting the beneficial effect of bisphosphonates (BPs) on bone disease of patients suffering from beta-thalassemia major (TM). Although BPs have been widely used, adverse events have been described including atypical femoral fractures (AFF). In the present case, a male adult patient suffering from TM sustained an AFF fulfilling(More)
OBJECTIVE We sought to compare the effects of combined calcium and vitamin D supplementation versus placebo on blood glucose and markers of inflammation in nondiabetic adults aged > or =65 years. RESEARCH DESIGN AND METHODS A total of 314 Caucasian adults without diabetes received either 500 mg calcium citrate and 700 IU vitamin D(3) or placebos daily for(More)
