The secretion of hormones is temporally precise and periodic, oscillating over hours, days,
and months. The circadian timekeeper within the suprachiasmatic nuclei (SCN) is central to …

In mammals, an internal timekeeping mechanism located in the suprachiasmatic nuclei
(SCN) orchestrates a diverse array of neuroendocrine and physiological parameters to …

The circadian clock in mammals regulates the sleep/wake cycle and many associated
behavioral and physiological processes. The cellular clock mechanism involves a …

Over recent years, a deeper comprehension of the molecular mechanisms that control
biological clocks and circadian rhythms has been achieved. In fact, many studies have …

Hormone secretion is highly organized temporally, achieving optimal biological functioning
and health. The master clock located in the suprachiasmatic nucleus (SCN) of the …

The nearly ubiquitous expression of endogenous 24 h oscillations known as circadian
rhythms regulate the timing of physiological functions in the body. These intrinsic rhythms …

Circadian rhythms govern several fundamental physiological functions in almost all
organisms, from prokaryotes to humans. The circadian clocks are intrinsic time-tracking …

A plethora of physiological processes show stable and synchronized daily oscillations that
are either driven or modulated by biological clocks. A circadian pacemaker located in the …

The circadian clock is an endogenous, time-tracking system that directs multiple metabolic
and physiological functions required for homeostasis. The master or central clock located …

In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus coordinates daily
rhythms including sleep–wake, hormone release, and gene expression. The cells of the …
