Circadian Rhythmicity in the Activities of Phenylalanine
The oscillations in phenylalanine aunnnia-lyase activity from Spirodels pelyrhiza and phenylalanine ammonia-lyase and tyrosine ammonia-lyase activities from Lemnas perpusilam disayed a circadian rhythm under continuous lght. Rhythmiclty in enzymic activity could not be detected in continuous darkness since under this condition phenylalanine ammonialyase activity remains at a fairly constantly l...
متن کاملCircadian Rhythmicity by Autocatalysis
The temperature compensated in vitro oscillation of cyanobacterial KaiC phosphorylation, the first example of a thermodynamically closed system showing circadian rhythmicity, only involves the three Kai proteins (KaiA, KaiB, and KaiC) and ATP. In this paper, we describe a model in which the KaiA- and KaiB-assisted autocatalytic phosphorylation and dephosphorylation of KaiC are the source for ci...
متن کاملDeveloping circadian rhythmicity in infants.
Circadian rhythms are endogenously generated rhythms with a period length of about 24-hrs. Evidence gathered over the past decade indicates that the circadian timing system develops prenatally and the suprachiasmatic nuclei, the site of a circadian clock, are present by mid-gestation in human and non-human primates. Recent evidence also shows that the circadian system of primate infants is resp...
متن کاملAbnormalities of circadian rhythmicity in liver disease.
U conditions, a wide range of biological processes exhibit a diurnal rhythm of approximately 24 h (the term circadian arises from the Latin, circaΩapproximately, diemΩday). The most obvious rhythm is the one related to variations in the sleep/wake cycle, but almost all aspects of the internal environment undergo such changes over a 24-h period. This oscillation occurs in parallel to ...
متن کاملMeal Time Shift Disturbs Circadian Rhythmicity along with Metabolic and Behavioral Alterations in Mice
In modern society, growing numbers of people are engaged in various forms of shift works or trans-meridian travels. Such circadian misalignment is known to disturb endogenous diurnal rhythms, which may lead to harmful physiological consequences including metabolic syndrome, obesity, cancer, cardiovascular disorders, and gastric disorders as well as other physical and mental disorders. However, ...
