Therapeutic potential of ginsenosides in circadian rhythm-based skin disorders

Journal of Ginseng Research
The circadian rhythm, a biological system all living organisms possess, has become increasingly important as sleep patterns become more irregular. Circadian rhythms affect various cell types (fibroblasts, fat cells, muscles, etc.) and organs (the liver ...

Identification of circadian rhythm

2016 24th Mediterranean Conference on Control and Automation (MED), 2016
We present an identification algorithm for determining the variables characterizing a circadian rhythm. This method is based on a recursive least square algorithm combined with an appropriate observer. It has the advantage of determining all the parameters of a time-varying circadian rhythm without requiring the knowledge of the period.

Circadian rhythms [PDF]

Current Opinion in Neurobiology, 1993
The neurobiological substratum of circadian rhythmicity encompasses three levels of integration: firstly, generation of time signals by circadian pacemakers; secondly, entrainment of pacemakers by environmental influences; thirdly, coupling of circadian pacemakers among themselves and with target systems responsible for the expression of overt rhythms.

Circadian Organization in Hemimetabolous Insects [PDF]

, 2004
The circadian system of hemimetabolous insects is reviewed in respect to the locus of the circadian clock and multioscillatory organization. Because of relatively easy access to the nervous system, the neuronal organization of the clock system in ...

Dietary control of circadian rhythm studies [PDF]

, 2023
Circadian rhythm is the natural internal 24-hour clock that is affected by light and the external environment, and it controls our wake and sleep cycle.

Voluntary exercise can strengthen the circadian system in aged mice [PDF]

, 2013
Consistent daily rhythms are important to healthy aging according to studies linking disrupted circadian rhythms with negative health impacts. We studied the effects of age and exercise on baseline circadian rhythms and on the circadian system's ability ...
