The mammalian circadian and sleep-wake systems are closely aligned through their
coordinated regulation of daily activity patterns. Although they differ in their anatomical …

The intrinsic cardiovascular regulatory system (β, 0.00013–0.02 Hz) did not adapt to
microgravity after a 6-month spaceflight. The infraslow oscillation (ISO, 0.01–0.10 Hz) …

Circadian cycle is a fundamental characteristic of life formed in the long-term evolution of
organisms and plays an important role in maintaining the proliferation, migration, and …

Background The high prevalence of desynchronized biological rhythms is becoming a
primary public health concern. We assess complex and diverse inter-modulations among …

The suprachiasmatic nucleus (SCN) of the hypothalamus consists of a highly
heterogeneous neuronal population networked together to allow precise and robust …

The study of circadian rhythms in physiology is part of chronobiology, a term coined in 1950
by Halberg (from the Greek “chronos” ¼ time,“bios” ¼ life, and “logos” ¼ science). 1 In 1959 …

With the growing appreciation that sleeping habits interact with health and aging, it is now
imperative to increase our understanding of exactly how sleep and age interact, influence …

The human menstrual cycle usually lasts approximately 28 days (24–32 days). In humans,
the ovarian and uterine endometrial cycles are known as the menstrual cycle. However, it is …

Disruptions within the circadian, metabolic, and immune systems contribute to the onset of
metabolic illnesses, including type 2 diabetes. This doctoral thesis aimed to examine the …
