Maintaining a stable circadian rhythm is essential for overall health. Disruption of this rhythm can alter the expression of clock genes and cancer-related genes, and affect many metabolic pathways and factors, thereby affecting the function of the immune system and contributing to the occurrence and...
The circadian clock is an endogenous timekeeper system that controls and optimizes biological processes, which are consistent with a master circadian clock and peripheral clocks and are controlled by various genes. Notably, the disruption of circadian cl

Drugs, both legal and illegal, have a strong impact on the central nervous system. While this can affect all types of circadian rhythms, sleep is one that is most apparent. For example, caffeine is a stimulant that can disrupt and push back your normal sleep cycle. Alcohol can do the op...
times of the day. For instance, while melatonin peaks at night in all vertebrates, glucocorticoids peak just prior to waking in both diurnal and nocturnal species9,10. Consequently, it is important to investigate how signals from the SCN are decoded to generate circadian rhythms in hormone ...
and there is also some evidence that indicates that the mentioned dietary patterns could ameliorate oxidative stress and inflammation [39,40]. Therefore, we aimed to investigate the impact of the following Mediterranean and DASH-style diets on mental health, circadian rhythm, and sleep quality in ...
Many biological processes in the intestine exhibit daily rhythms that are generated by the circadian clock. However, the intestine is unique in that many of its circadian rhythms also require the gut microbiota. For example, the microbiota coordinates with the circadian clock to generate rhythms in...
This review focuses on the circadian timing of mammalian parturition, particularly in the human. It is proposed that differences in the phasing of parturition among different species are likely a function of opposite uterine responses to humoral cues, in particular those coding for time of day. ...
1). Exposure to ALAN is known to promote nighttime activity in diurnal species. In birds, nighttime activity increases mainly by shifting the beginning of activity earlier into the night (e.g.13). Examples of nocturnal species altering behavioral patterns in response to ALAN are numerous (e.g...
however, the opposite trend is observed (Maleszka et al.2013; Park et al.2022). Female rats in late proestrus have higher amounts of OX1R and OX2R in their MBH (Silveyra et al.2007b), which highlights the species-specific nature of estrous cycle-dependent orexin functionality in the MB...
