Plasma (carotenoids, retinol, alpha-tocopherol) and tissue (carotenoids) levels after supplementation with beta-carotene in subjects with precancerous and cancerous lesions of sigmoid colon

Article Abstract:

Colorectal cancer is widespread throughout the world and its incidence has risen during the past 10 years. Subjects who take a high quantity of antioxidants may have a reduced risk of colorectal cancer. Some studies have suggested a possible chemopreventive role of beta-carotene towards neoplasm in the gastrointestinal tract. Tissue and plasma carotenoids in healthy subjects and those with pre-cancer and cancer lesions and the effects of beta carotene supplementation on carotenoid concentration in tissue was evaluated. Beta-carotene was found to make significant increases in tissue concentration.

The basal metabolic rate and energy cost of standardised walking of short and tall men

Article Abstract:

Absolute values of basal metabolic rate (BMR) are higher in taller people while lower in shorter ones. However, tall people have lower BMR values than shorter individuals when BMR is expressed per kg body weight of fat-free mass (FFM). Stature does not affect the energy cost of walking when expressed as net cost per kg FFM. These were gleaned from a study of the influence of stature on the BMR and the energy cost of standardized walking.

Body composition changes in anorexia nervosa

Article Abstract:

Changes in body composition associated with anorexia nervosa were investigated. Twenty women suffering from anorexia nervosa participated in the study designed to assess body fat, total body water, skeletal mass and radius bone mineral density. Results showed that anorexia nervosa results in lower body fat, muscle mass and bone mass. Patients appear to regain their body fat more than their muscle mass after medium-term recovery.
