Biological rhythms have a crucial role in sha** the biology and ecology of organisms.
Light pollution is known to disrupt these rhythms, and evidence is emerging that chemical …

Circadian rhythms are intrinsic molecular mechanisms that synchronize biological functions
with the day/night cycle. The mammalian gut is colonized by a myriad of microbes …

Introduction Previous research has reported that the gut microbiota performs an essential
role in sleep through the microbiome–gut–brain axis. However, the causal association …

Aging is a complex process involving various systems and behavioral changes. Altered
immune regulation, dysbiosis, oxidative stress, and sleep decline are common features of …

Background DNA methylation integrates environmental signals with transcriptional
programs. COVID-19 infection induces changes in the host methylome. While post-acute …

The accelerated pace of life at present time has resulted in tremendous alterations in living
patterns. Changes in diet and eating patterns, in particular, coupled with irregular light–dark …

Introduction Poor sleep quality is closely associated with comorbidities affecting a multitude
of organ systems. Among the sleep disorders in the population, there has recently been an …

Organisms subjected to periodic nutrient limitation early in life exhibit improvements in
aspects of survival, including resistance to some environmental stressors. Recent findings …

Abstract In 1976, Pittendrigh and Daan established a theoretical framework which has
coordinated research on circadian clock entrainment and photoperiodism until today. The …

Circadian rhythms influence various aspects of the biology and physiology of the host, such
as food intake and sleep/wake cycles. In recent years, an increasing amount of genetic and …
