Biochemistry That Times the Day

Biochemistry That Times the Day

“Timing is everything” appears to be a motto not limited to human existence. In fact, keeping track of time is so important that organisms ranging from algae and insects to mammals rely on circadian clocks, endogenous molecular oscillators with a period of approximately 24 h, to regulate diverse processes that include the cell cycle, gene expression, and metabolism. Although all biological cloc...

Thermoregulatory responses to cold water at different times of day.

This study examined how time of day affects thermoregulation during cold-water immersion (CWI). It was hypothesized that the shivering and vasoconstrictor responses to CWI would differ at 0700 vs. 1500 because of lower initial core temperatures (T(core)) at 0700. Nine men were immersed (20 degrees C, 2 h) at 0700 and 1500 on 2 days. No differences (P > 0.05) between times were observed for meta...
