However, this cycle is controlled via complicated cellular pathways with feedback loops. It is widely known that changes in the circadian rhythm can alter some metabolic pathways of body cells and could affect the treatment process, particularly for metabolic diseases like T2DM....
The Circadian rhythm is a natural cycle of physical, mental, and behavioral changes that the body goes through in a 24-hour cycle. Circadian rhythms are mostly affected by light and darkness and are controlled by a small area in the middle of the brain. Now, a new study in mice led by...
However, they reflect a ubiquitous temporal programme called the circadian clock. In the absence of either anatomical clock structures or clock genes, the timing of sleep and wakefulness is disrupted. The complex nature of circadian behaviour is evident in the fact that phasing of the cycle during...
上文“Aside from sleeping at night and waking during the day, each cycle involves many factors. Not everyone has an identical circadian rhythm.(除了晚上睡觉和白天醒来之外,每个周期还涉及许多因素。并非每个人都有相同的昼夜节律。)”提到并不是每个人都有相同的昼夜规律,除了晚上睡觉和白天醒来之外,还有其...

On the basis of the catalytic cycle of PRX family members and their ancient evolutionary origins15, it has been suggested that these essential antioxidant proteins themselves constitute the basis of a self-sustained post-translational circadian redox oscillation16. Alternatively, and as observed in othe...
Circadian systems are biological oscillators that orchestrate activities through an elaborate network of interactive proteins and feedback loops. All clocks rely on transfer of phosphate groups, called phosphorylation, to clock proteins for setting the 24-hour cycle. Both studies looked at phosphorylation...
the natural sleep cycle—and, as a consequence, the regular dream cycle—is altered. Shift workers often sleep less, for example, as a result of the greater state of physiological arousal that accompanies the circadian rhythm’s daylight cycle. Current research indicates that reduction in total ...
Our body’s innate rhythms are proving to be more interconnected than we previously thought. Our systems do not work in isolation but rather are parts of a whole and should be treated as such. The circadian rhythm is no exception to this rule....
The circadian clock is an endogenous time-tracking system that anticipates daily environmental changes. Misalignment of the clock can cause obesity, which is accompanied by reduced levels of the clock-controlled, rhythmic metabolite NAD+. Increasing NAD+
