BACKGROUND Physical activity (PA) is suggested to contribute to fat loss not only through increasing energy expenditure "per se" but also increasing muscle mass; therefore, it would be interesting to better understand the specific associations of PA with the different body's components such as fat mass and muscle mass. The aim of the present study was to examine the association between objectiv...

abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...

abstract background: pregnancy with anxious or depressive symptoms might be associated with worse birth outcomes. the aim of this study was to determine the demographic predictors of anxiety and depression symptoms in pregnant women. materials and methods: we assessed pregnancy anxiety and depression levels among 142 women in three trimesters. all subjects completed two questionnaires: demograp...

BACKGROUND Age-related declines in skeletal muscle mass and strength, representing "sarcopenia," are a growing concern in aging societies. However, the prevalence of low muscle mass based on the height2-adjustment has been shown to be extremely low, and a more appropriate definition of low muscle mass is needed, particularly for Asian women. The aim of this study was to explore the most appropr...

OBJECTIVE To assess bone-muscle (B-M) indices as risk factors for incident fractures in men. METHODS Participants of the Osteoporotic Fractures in Men (MrOS) Study completed a peripheral quantitative computed tomography scan at 66% of their tibial length. Bone macrostructure, estimates of bone strength, and muscle area were computed. Areal bone mineral density (aBMD) and body composition were...

We construct a marriage market model of matching along multiple dimensions, some of which unobservable, where individual preferences can be summarized by a one-dimensional index combining the various characteristics. We show that, under testable assumptions, these indices are ordinally identi…ed, and that the male and female trade-o¤s between their partners’characteristics are overidenti…ed. Us...

CONTEXT Positive learning experiences for students on clinical placement in rural settings have the potential for supporting the recruitment of qualified nurses to these areas. Recruitment of such nurses is a global concern because current shortages have resulted in decreased healthcare quality for rural residents. By understanding the challenges faced by nursing students unfamiliar with rural ...
