Biological clocks [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
Circadian rhythms describe biological phenomena that oscillate with an ≈24-hour cycle. These rhythms include blood pressure, body temperature, hormone levels, the number of immune cells in blood, and the sleep-wake cycle. In this paper, we will focus on common genes between species that are responsible for determining the circadian behavior ...

The circadian clock influences T cell responses to vaccination by regulating dendritic cell antigen processing

open access: yesNature Communications, 2022
Circadian rhythms are known to impact a range of biological processes including in the immune system. Here the authors show how circadian rhythms modulate the T cell response to vaccination via regulation of dendritic cell metabolism.

The Biological Clock: A Pivotal Hub in Non-alcoholic Fatty Liver Disease Pathogenesis. [PDF]

open access: yesFront Physiol, 2018
Non-alcoholic fatty liver disease (NAFLD) is the most frequent hepatic pathology in the Western world and may evolve into steatohepatitis (NASH), increasing the risk of cirrhosis, portal hypertension and hepatocellular carcinoma.

Interaction between the Circadian Clock and Regulators of Heat Stress Responses in Plants. [PDF]

open access: yes, 2020
The circadian clock is found ubiquitously in nature, and helps organisms coordinate internal biological processes with environmental cues that inform the time of the day or year.

The advantage of being slow: the quasi-neutral contact process [PDF]

open access: yes, 2017

The Biological Clock: Age, Risk, and the Biopolitics of Reproductive Time

open access: yesSex Roles, 2020
The present article explores the social and subjective dimensions of the biological clock and its implications for reproductive time through a qualitative study based on 40 life story interviews of women from Santiago de Chile.

How does diurnal intermittent fasting impact sleep, daytime sleepiness, and markers of the biological clock? Current insights. [PDF]

open access: yesNat Sci Sleep, 2018
Mealtimes and feeding schedules may interfere with the circadian system and impact sleep. The practice of intermittent fasting (IF) in its different formats is increasing worldwide.

The Biological Clock is Regulated by Adrenergic Signaling in Brown Fat but is Dispensable for Cold-Induced Thermogenesis

open access: goldPLoS ONE, 2013
The biological clock plays an important role in integrating nutrient and energy metabolism with other cellular processes. Previous studies have demonstrated that core clock genes are rhythmically expressed in peripheral tissues, including the liver ...

Consequences and management of sleep-wake rhythm disorders resulting from social jetlag and nightshifts

open access: yesJournal of Education, Health and Sport, 2023
Our day to night cycle is ruled by a social, biological and sun clock. The social clock being a local time is aligned with others’ lives. The biological clock (circadian time) that controls our physiology and the sun clock that defines natural light and
