Sleep biological rhythms in normal infants and those at high risk for SIDS.

abstract：:The circadian rhythms of food and water consumption, the number of feeding and drinking episodes, oxygen consumption, carbon dioxide production, respiratory quotient, gross motor activity, and body temperature were measured in male B6C3F1 mice that were fed ad libitum (AL) or fed a caloric-restricted diet (CR). The CR...
