The demonstrated health benefits of active commuting (AC) and low participation rates among older adults indicate a need to examine the socioecological correlates of AC by age category. An online survey of employed U.S. adults examined AC participation and individual, employment-related, community, and environmental variables. Participants were dichotomized by age ...

Aging nephropathy is characterized by podocyte depletion, accompanied by progressive glomerulosclerosis. Replacement of terminally differentiated podocytes by local stem/progenitor cells is likely a critical mechanism for their regeneration. Recent studies have shown that cells of renin lineage (CoRL), normally restricted to the kidney's extra-glomerular compartment, might serve this role following ...

Older people increasingly constitute a large proportion of the acute coronary syndrome (ACS) population. We examined the relationship of age with receipt of more intensive management and secondary prevention medicine. Then, the comparative association of intensive management (reperfusion/angiography) over a conservative strategy on time to death was investigated by age. ...

Background: vascular disease has been postulated to contribute to muscle dysfunction in old age. Previous studies examining the effects of cardiovascular drugs on muscle function have shown conflicting results. We therefore examined the association of angiotensin converting enzyme (ACE) inhibitor, thiazide and statin use with decline in grip strength in ...

Polyandrous females are expected to discriminate among males through postcopulatory cryptic mate choice. Yet, there is surprisingly little unequivocal evidence for female-mediated cryptic sperm choice. In species in which nuptial gifts facilitate mating, females may gain indirect benefits through preferential storage of sperm from gift-giving males if the gift signals ...

Accurately measuring blood pressure (BP) requires choosing an appropriate BP cuff size. This study examined trends in mid-arm circumference (mid-AC) and in the distribution of appropriate BP cuffs using 1999-2010 National Health and Nutrition Examination Survey (NHANES) data. NHANES uses a complex multistage probability sample design to select participants who ...

Eriophyoid females store sperm either asymmetrically in one spermatheca, or symmetrically in both spermathecae. Previous studies have suggested that species in which females store sperm asymmetrically pick up sperm from only one spermatophore, while those with symmetrical sperm storage pick up sperm from two or more spermatophores during their lifetime. ...

In a variety of taxa, males deploy alternative reproductive tactics to secure fertilizations. In many species, small "sneaker" males attempt to steal fertilizations while avoiding encounters with larger, more aggressive, dominant males. Sneaker males usually face a number of disadvantages, including reduced access to females and the higher likelihood that ...

Mating between relatives usually decreases genetic quality of progeny as deleterious recessive alleles are expressed by inbred individuals. Inbreeding degrades sperm traits but its effects on sperm storage and fate within females are currently unknown. We quantified the relationship between the degrees of inbreeding relevant to natural populations (f = ...

Abstract Purpose: Previous studies have reported variation in stimulus accommodative convergence to accommodation (AC/A) ratio across differing accommodative stimuli. Response AC/A ratio was assessed across 4 accommodative demands to determine if these differences could be due to accommodative inaccuracies to stimuli. Methods: Twenty-three student participants aged 18 to 26 years ...

Sperm competition is a powerful and widespread evolutionary force that drives the divergence of behavioural, physiological and morphological traits. Elucidating the mechanisms governing differential fertilization success is a fundamental question of sperm competition. Both sperm and nonsperm ejaculate components can influence sperm competition outcomes. Here, we investigate the role of ...

Sexual selection may operate on pre-copulatory, copulatory, and post-copulatory traits. An example of a copulatory target of sexual selection is the genitalic movements a male performs during copulation. These movements may function either to prevent sperm competition or to influence a female's fertilization decision. Here we investigated how copulation duration, ...

Post-mating sexual selection by means of sperm competition or cryptic female choice occurs in species in which females remate before exhausting sperm supplied by previous mates. Thus, sperm competition is expected to be stronger when inseminated females remate more frequently or take longer to deplete sperm load. Previous studies comparing ...

Recent evidence shows that females exert a post-copulatory fertilization bias in favour of unrelated males to avoid the genetic incompatibilities derived from inbreeding. One of the mechanisms suggested for fertilization biases in insects is female control over transport of sperm to the sperm-storage organs. We investigated post-copulatory inbreeding-avoidance mechanisms in ...
