In most situations involving a significant change in body weight, both fat-free body mass (FFM) and body fat participate, but the relative contribution of FFM and fat to the total weight change is influenced by the initial body fat content. Overfeeding: In experiments of at least 3-weeks' duration, the weight gain of thin people comprises 60-70% lean tissues, whereas in the obese it is 30-40%. ...

BACKGROUND The development of obesity is still a poorly understood process that is dependent on both genetic and environmental factors. OBJECTIVE The objective was to examine how physical activity and the proportion of energy as protein in the diet modify the genetic variation of body mass index (BMI), waist circumference, and percentage body fat. DESIGN Twins from Denmark (756 complete pai...

A comparative study was conducted on the ontogenetic variation in morphometry of a total of 29 shellbearing molluscan species occurring on an intertidal stony shore in south-western Japan. The relationships between shell size and total weight and between shell size and ̄esh weight were all highly signi®cant on logarithmic scales with the slopes having values of about three. The arcsine-transfor...

introduction: the impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male wistar rats (80-100 g body weight). material & method: it was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight along...

genetic parameters direct and maternal in fars native flows using the bayesian statistical approach, was estimation with consider body weight at a day of age (bw1), body weight at eight weeks of age (bw8), body weight at 12 weeks of age (bw12), age at sexual maturity (asm), egg number (egp) and mean egg weight during 28th, 30th and 32nd week ages (av283032) fars native flows. genetic parameters...

OBJECTIVES To investigate the relationship between endogenous androgens and body fat distribution in early and late postmenopausal women. MATERIALS AND METHODS We enrolled postmenopausal women consisting of an early group (≤ 5 years since menopause, n = 105) and a late group (≥ 10 years since menopause, n = 107). Each group was subdivided into normal weight (BMI <24 kg/m(2)) group, overweight...

This study was conducted to investigate the effects of different energy intake on physical and chemical composition in body fractions, growth performance and meat characteristics of finishing barrows and gilts. A total of twenty six crossbred (Landrace× Yorkshire) consisting of 16 barrows and 13 gilts were used in this study. The animals were allocated by sex to two treatments to form a 2×2 fac...

this study was conducted to investigate direct and maternal effects on some economic traits in north iranian native fowls. traits considered were body weight at 1 day of age (bw1), body weight at 8 weeks of age (bw8), body weight at 12 weeks of age (bw12), egg number (en) during the first 12 weeks of laying period, egg weight at 1st day of laying (ew1), mean egg weight at 28th, 30th and 32nd we...
