the increasing processes of body and heart weight, the index changes of heart to body weight ratio and of heart walls thickness (ventricular and inter ventricular) were studied on 160 goat fetuses (2groups male and female) from 7 to 22 week ages (at the first to the end of fetal period). data analysis in spss and by anov a showed that the influence of age in all of 6 studied parameters was sign...

OBJECTIVE To investigate the variations in body weight, food intake, and body composition of both male and female C57BL/6J mice during a diet-induced obesity model with high-fat diet (HFD) feeding. METHODS Mice were individually housed and fed ad libitum either a low-fat diet (LFD, 10% calories from fat; n = 15 male, n = 15 female) or HFD (45% calories from fat; n = 277 male, n = 278 female) ...

Female hypocretin knockout (Hcrt KO) mice have increased body weight despite decreased food intake compared to wild type (WT) mice. In order to understand the nature of the increased body weight, we carried out a detailed study of Hcrt KO and WT, male, and female mice. Female KO mice showed consistently higher body weight than WT mice, from 4 to 20 months (20-60%). Fat, muscle, and free fluid l...

BACKGROUND "Fitspiration" (also known as "fitspo") aims to inspire individuals to exercise and be healthy, but emerging research indicates exposure can negatively impact female body image.

OBJECTIVE The aim of our stu...

The Charadrii (shorebirds, gulls and alcids) are one of the most diverse avian groups from the point of view of sexual size dimorphism, exhibiting extremes in both male-biased and female-biased dimorphism, as well as monomorphism. In this study we use phylogenetic comparative analyses to investigate how size dimorphism has changed over evolutionary time, distinguishing between changes that have...

The aim of this study was to evaluate the single oral dose toxicity of Bupleuri Radix (BR) aqueous extracts, it has been traditionally used as anti-inflammatory agent, in male and female mice. BR extracts (yield = 16.52%) was administered to female and male ICR mice as an oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration ...
