The pronounced daily variation in the release of adrenal hormones has been at the heart of
the deciphering and understanding of the circadian timing system. Indeed, the first …

Simple Summary In mammals, circadian rhythms in nearly all behaviors and physiological
processes are controlled by the suprachiasmatic nucleus, a collection of neurons in the …

The mammalian circadian timing system is organized in a hierarchy, with the master clock
residing in the suprachiasmatic nucleus (SCN) of the hypothalamus and subsidiary …

The temporal niche that an animal occupies includes a coordinated suite of behavioral and
physiological processes that set diurnal and nocturnal animals apart. The daily rhythms of …

The diurnal rhythm of glucocorticoid secretion depends on the suprachiasmatic (SCN) and
dorsomedial (putative food-entrainable oscillator; FEO) nuclei of the hypothalamus, two …

Key features: Serves as the detailed, authoritative source of the clinical chemistry of the most
commonly used laboratory animals Includes detailed chapters dedicated to descriptions of …

As a consequence of the Earth's rotation, almost all organisms experience day and night
cycles within a 24-hr period. To adapt and synchronize biological rhythms to external daily …

The circadian production of glucocorticoids involves the concerted action of several factors
that eventually allow an adequate adaptation to the environment. Circadian rhythms are …

Circadian rhythms are generated by endogenous clocks in the central brain oscillator, the
suprachiasmatic nucleus (SCN), and peripheral tissues. The molecular basis for the …

Aim: In the present study, we report the circadian profiles of a wide panel of hormones
measured in rats and common marmosets (Callithrix jacchus), under physiological …
