The emergence of circadian timekeeping in the intestine
Nature CommunicationsThe circadian clock is a molecular timekeeper, present from cyanobacteria to mammals, that coordinates internal physiology with the external environment.

SnapShot: Circadian Clock Proteins
Cell, 2008 The earth’s rotation about its axis generates predictable changes in light and temperature, which define the 24 hr day-night cycle. Organisms from bacteria to humans have evolved an internal timekeeper to anticipate these environmental changes. This timekeeper—the circadian clock—allows organisms to parse biological processes to the appropriate time of

Clinical Pharmacology &Therapeutics, EarlyView.Accurately assessing glomerular filtration rate (GFR) from plasma creatinine concentrations is challenging in patients with unstable renal function. This study aimed to refine the understanding of creatinine kinetics for more reliable assessments of GFR and net creatinine tubular secretion (nCTS) via OCT2/MATE in humans.

Demonstration of Circadian Rhythm in Heart Rate Turbulence using Novel Application of Correlator Functions [PDF]
arXiv, 2006 Background: It has been difficult to demonstrate circadian rhythm in the two parameters of heart rate turbulence, turbulence onset (TO) and turbulence slope (TS). Objective: To devise a new method for detecting circadian rhythm in noisy data, and apply it to selected Holter recordings from two post-myocardial infarction databases, Cardiac Arrhythmia ...

The Circadian Clock Mutation Promotes Intestinal Dysbiosis.
Alcoholism: Clinical and Experimental Research, 2016 BACKGROUND Circadian rhythm disruption is a prevalent feature of modern day society that is associated with an increase in pro-inflammatory diseases, and there is a clear need for a better understanding of the mechanism(s) underlying this phenomenon.

ChemSusChem, EarlyView.Redox mediators are essential to promote the electrogenic activity of cyanobacteria in biophotovoltaics. In this work, we systematically evaluates three representative mediators about their influence on the cyanobacterial growth, photosynthetic efficiency, and electrogenic activity. The results reveal distinct impacts of different mediators, despite of

What season suits you best? Seasonal light changes and cyanobacterial competition [PDF]
arXiv, 2013 Nearly all living organisms, including some bacterial species, exhibit biological processes with a period of about 24 h called circadian (from the Latin circa, about, dies, day) rhythms. These rhythms allow living organisms to anticipate the daily alternation of light and darkness.

Circadian clock during plant development
Journal of plant research, 2017 Plants have endogenous biological clocks that allow organisms to anticipate and prepare for daily and seasonal environmental changes and increase their fitness in changing environments.
