Methods Lenticular AF was imaged with 488-nm excitation using a confocal scanning laser ophthalmoscope (cSLO) routinely used for retinal AF imaging. Th...

OBJECTIVE Age-associated insulin resistance may underlie the higher prevalence of type 2 diabetes in older adults. We examined a corollary hypothesis that obesity and level of chronic physical inactivity are the true causes for this ostensible effect of aging on insulin resistance. RESEARCH DESIGN AND METHODS We compared insulin sensitivity in 7 younger endurance-trained athletes, 12 older athl...

Most cases of AAA are asymptomatic and often discovered incidentally. Approximately the initial presentation in 12% of cases of AAA is sudden rupture with subsequent high mortality. This study was performed to evaluate the prevalence and screening necess...

The effects of aging on response time (RT) are examined in 2 lexical-decision experiments with young and older subjects (age 60-75). The results show that the older subjects were slower than the young subjects, but more accurate. R. Ratcliff s (1978) diffusion model provided a good account of RTs, their distributions, and response accuracy. The fits show an 80-100-ms slowing of the nondecision ...

Additionally, we examine the effect of resistance-type exercise training on the muscle transcriptome in healthy older subjects and (pre-)frail older adul...
