Circadian rhythms and obesity: Timekeeping governs lipid metabolism
Journal of Pineal Research, 2020Almost all living organisms have evolved autoregulatory transcriptional‐translational feedback loops that produce oscillations with a period of approximately 24‐h. These endogenous time keeping mechanisms are called circadian clocks. The main function of

1997 marks the 25th anniversary of the discovery of the master circadian pacemaker in mammals in the hypothalamic suprachiasmatic nucleus. Remarkable progress has been made over the last 25 years in elucidating the physiological mechanisms involved in the entrainment, generation and expression of circadian rhythms at the cellular and systems levels ...

Circadian rhythm sleep disorders occur when individuals attempt to sleep at the wrong circadian time. The misalignment between the internal circadian timing system and the external environment is typically due to either an alteration in the functioning of the circadian timing system (e.g., delayed or advanced sleep phase disorder) or to changes in the ...

Bile acids Metabolism and Circadian Rhythms.
American Journal of Physiology - Gastrointestinal and Liver Physiology, 2020Circadian rhythms are biological systems that synchronize cellular circadian oscillators with the organism's daily feeding-fasting or rest-activity cycles in mammals.

All forms of life, from the simplest cells to the most complex organisms, show periodicity in some of their biologic activities and functions. The most common of these rhythmic events are those that we refer to as "circadian" (circa, around; dias, day).

CYANOBACTERIAL CIRCADIAN RHYTHMS
Annual Review of Plant Physiology and Plant Molecular Biology, 1997▪ Abstract Evidence from a number of laboratories over the past 12 years has established that cyanobacteria, a group of photosynthetic eubacteria, possess a circadian pacemaker that controls metabolic and genetic functions. The cyanobacterial circadian clock exhibits the three intrinsic properties that have come to define the clocks of eukaryotes: The

Circadian rhythms during pregnancy
Endocrine Reviews, 19931. Introduction ADAPTATIONS to our environment are of two types: reactive, in which the adaptation follows an environmental change, and predictive, in which the organism anticipates the environmental change before it takes place. We live in an organized environment in which day and night, seasons, and tides alternate.

Abstract: Circadian rhythms are driven by biological clocks and are endogenous in origin. Therefore, circadian changes in the metabolism or secretion of endogenous glucocorticoids are certainly responsible in part for the time‐dependent changes observed in the inflammatory response and arthritis.
