Tbc1d1 is a Rab GTPase-activating protein (GAP) implicated in regulating intracellular retention and cell surface localization of the glucose transporter GLUT4 and thus glucose uptake in a phosphorylation-dependent manner. Tbc1d1 is most abundant in skeletal muscle but is expressed at varying levels among different skeletal muscles. Previous studies with male Tbc1d1-deficient (Tbc1d1(-/-)) mice...

This paper examines differences between wireless ultra wideband radio channels when various test persons are measured. The work bases on static on-body measurements conducted in an anechoic chamber at the frequency range of 2-8 GHz by using a vector network analyzer. Three male and one female test persons were measured. The study was repeated by using two different planar antenna types: dipole ...

BACKGROUND The prevalence of obesity has increased dramatically. A direct comparison in the predisposition to obesity between males, premenopausal females, and postmenopausal females with various caloric intakes has not been made. To determine the effects of sex and ovarian hormones on the susceptibility to obesity, we conducted laboratory studies with mice. To eliminate confounders that can al...

Hypothalamic damage was induced in age-matched male and female albino mice by goldthioglucose injection, and their food consumption and body weight were compared over the following 60-day period. Sex differences in food consumption were also investigated as a function of palatability of food. Results show no significant sex differences in food consumption, although marked sex differences in bod...

A formula is given, allowing a value for total body fat to be calculated from skinfold thickness measurements at two sites (subscapular and triceps), in conjunction with nine body dimensions. For newborn infants total body fat so calculated accorded satisfactorily with published data from cadaver analyses. The formula has been tentatively applied to infants up to the age of 40 weeks, and to pre...

The adaptive canalization hypothesis predicts that traits with low phenotypic plasticity are more fitness relevant, because they have been canalized via strong past selection, than traits with high phenotypic plasticity. Based on differing male body size plasticities of the predatory mites Phytoseiulus persimilis (low plasticity) and Neoseiulus californicus (high plasticity), we accordingly hyp...

PURPOSE Lower limb skin-fold thicknesses have been differentially associated with sex in elite runners. Front thigh and medial calf skin-fold appear to be related to 1,500m and 10,000m time in men but 400m time in women. The aim of the present study was to compare anthropometric and training characteristics in recreational female and male half-marathoners. METHODS The association between both...

The aim of the study was to compare the growth performance and carcass quality of layer-type cockerels and broilers reared under identical conditions. A total of 180 one-day-old broiler male (BM), broiler female (BF) and brown layer male (LM) chicks were distributed into 9 floor pens in a completely randomized design, with 3 replicates of 20 birds per experimental unit. The body weights and fee...

A growing body of evidence shows that female birds use male plumage coloration as an important criterion in mate choice. In the field, however, males with brighter coloration may both compete better for high quality territories and be the object of female choice. Positive associations between territory quality, male-male competitive ability, and female preferences can make it difficult to deter...
