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 ...

Prior studies, all using SPECT techniques, failed to find any differences for dopamine transporter (DAT) in restless legs syndrome (RLS) subjects. The distinct pharmacokinetic properties associated with SPECT-determined DAT along with rapid biodynamic changes in DAT may, however, have missed membrane-bound DAT differences. The current studies assessed real-time DAT binding ...

There is very little research on Alaska Native (AN) elders and how they subjectively define a successful older age. The lack of a culturally-specific definition often results in the use of a generic definition that portrays Alaska Native elders as aging less successfully than their White counterparts. However, there is ...

Life-history theory predicts that increased predation on juvenile age/size-classes favors delayed maturation and decreased reproductive investment. Although this theory has received correlative support, experimental tests in nature are rare. In 1976 and 1981, guppies (Poecilia reticulata) were transplanted into localities that previously only contained a killifish, Rivulus hartii. This situation ...

We measured age-specific fecundity and survival in recombinant inbred lines of Drosophila melanogaster that were derived from an artificial selection experiment for delayed reproduction. Age at peak oviposition is highly heritable (h(2) (B) = 0.55). We find three qualitative categories of peak oviposition: early-, midlife-, and bimodal. Genetic correlations between ...
