TL;DR: The performance of elite athletes is likely to defy the types of easy explanations sought by scientific reductionism and remain an important puzzle for those interested in physiological integration well into the future.

TL;DR: An overview of convalescent plasma is provided, from evidence of benefit, regulatory considerations, logistical work flow and proposed clinical trials, as scale up is brought underway to mobilize this critical resource.

TL;DR: There are at least two independent mechanisms contributing to the rise in SkBF during nonpainful local heating: a fast-responding vasodilator system mediated by the axon reflexes and a more slowly responding vasodILator system that relies on local production of NO.

TL;DR: The results demonstrate that reduced insulin sensitivity is likely related to changes in adiposity and to physical inactivity rather than being an inevitable consequence of aging and show that regular endurance exercise partly normalizes age-related mitochondrial dysfunction, although there are persisting effects of age on mtDNA abundance and expression of nuclear transcription factors and mitochondrial protein.

TL;DR: The present study suggests that the hormonal fluctuations that occur during the normal menstrual cycle may alter sympathetic outflow but not the transduction of sympathetic activity into vascular resistance.
