Recent literature has been predominantly observational, describing how both critical illness and the ICU environment might impair normal sleep and impact circadian rhythm. Emerging consensus guidance outlines the need for standardized light metrics in clinical trials investigating effects of light therapies. ...
灯光对昼夜节律的影响 Light effects on circadian rhythm 光线对昼夜节律的影响就是光线对昼夜节律的影响。 大多数动物和其他生物的大脑中都有“内置时钟”,用于调节生物过程和日常行为的时间。这些“时钟”被称为昼夜节律。它们允许相对于自然界中的24小时昼/夜周期维护这些过程和行为。尽管这些节奏由各个生物体维持,...
How light impacts our circadian rhythm and, consequently, our health Light is the strongest mechanism we have for synchronizingour internal body clockswith the world around us. But our everyday lives, which are often spent indoors in dim artificial light, easily throw our natural circadian rhythm ...
“To control for outside influences on circadian rhythm, researchers removed all external time cues from the lab’s environment, including clocks and access to natural light,” the university said. Participants were given six opportunities to eat at fixed times and could consume as much foo...
We study the impact of light on the mammalian circadian system using the theory of phase response curves. Using a recently developed ansatz we derive a low-dimensional macroscopic model for the core circadian clock in mammals. Significantly, the variables and parameters in our model have ...
work schedules should accommodate circadian rhythm “chronotypes,” which vary a bit from individual to individual. Blackout curtains and an eye mask will help sleepers in the summer, when the sun rises before it is time to wake up. Melatonin supplements should be used, but o...

作者:Flynn-Evans, Erin E.;Skene, Debra J.;Lockley, Steven W.;Tabandeh, Homayoun; 摘要: Light is the major environmental time cue that synchronizes the endogenous central circadian pacemaker, located in the suprachiasmatic nuclei of the hypothalamus, and is detected exclusively by the eyes prim...
We found that the individual light/dark (LD) reversal showed a tissue- and gene-specific effect on the circadian phases of peripheral clock genes, which was generally similar between the control and diabetic rats. In the liver and heart, the peak phases of examined clock genes (Bmal1, Rev-...
The systems biology study of the current epidemic of chronic disease has exposed significant pathophysiology related to disorders of the circadian rhythm.
