A stochastic actor-based model was used to investigate the origins of sex segregation by examining how similarity in sex of peers and time spent in gender-typed activities affected affiliation network selection and how peers influenced children's (N = 292; Mage = 4.3 years) activity involvement. Gender had powerful effects on ...

Through multiple group structural equation modeling analyses, path models were used to test the predictive effects of sport type and both interpersonal (i.e., mothers' body dissatisfaction, family dynamics) and intrapersonal factors (i.e., athletic self-efficacy, body mass index [BMI]) on high school female sport participants' (N=627) body dissatisfaction. Sport types were ...

Nitric oxide synthase-1 (NOS1) is involved in several forms of plasticity including hippocampal-dependent learning and memory, experience-dependent plasticity in the barrel cortex, and long-term potentiation (LTP) in the hippocampus and neocortex. NOS1 also contributes to ischemic damage during stroke and has a stronger deleterious effect in males than females. We ...

Vocal duetting occurs in many taxa, but its function remains much-debated. Like species in which only one sex sings, duetting birds can use their song repertoires to signal aggression by singing song types that match those of territorial intruders. However, when pairs do not share specific combinations of songs (duet ...

Studies across and within species suggest that hippocampus size is sexually dimorphic in polygamous species, but not in monogamous species. Although hippocampal volume varies with sex, season and mating system, few studies have simultaneously tested for sex and seasonal differences. Here, we test for sex and seasonal differences in the ...

Vitamin D deficiency is a serious global issue. Although the serum 25-hydroxyvitamin D [25(OH)D] test is generally the most accurate way to assess vitamin D levels, the optimal range of 25(OH)D has yet to be established. Moreover, the optimal level may vary according to race, region, and age. Suboptimal vitamin ...

We have previously shown that aging is associated with weakened rat mesenteric lymphatic vessel (MLV) contractility. However, the specific mechanisms contributing to this aging-associated contractile degeneration remain unknown. Aging is often associated with elevations in oxidative stress, and reactive oxygen species (ROS) have been shown to reduce the contractility of ...

Background:  It has long been known women lose satisfaction with their hair with aging. Our data show that Caucasian women perceive a decrease in hair amount in their mid-40s with a further decrease in the mid- to late-50s, which leads to this dissatisfaction. Neither loss of density (hairs/cm(2) ) nor ...
