Neurotransmitters of the suprachiasmatic nuclei
Journal of Circadian Rhythms, 2006 There has been extensive research in the recent past looking into the molecular basis and mechanisms of the biological clock, situated in the suprachiasmatic nuclei (SCN) of the anterior hypothalamus.

Inverse relationship between genetic diversity and epigenetic complexity [PDF]
, 2008 Early studies of molecular evolution revealed a correlation between genetic distance and time of species divergence. This observation provoked the molecular clock hypothesis and in turn the ‘Neutral Theory’, which however remains an ...

Limited water stress modulates expression of circadian clock genes in Brachypodium distachyon roots
Scientific Reports, 2023 Organisms have evolved a circadian clock for the precise timing of their biological processes. Studies primarily on model dicots have shown the complexity of the inner timekeeper responsible for maintaining circadian oscillation in plants and have ...

The Tibetan medicine Zuotai influences clock gene expression in the liver of mice [PDF]
PeerJ, 2016 Background. The circadian clock is involved in drug metabolism, efficacy and toxicity. Drugs could in turn affect the biological clock as a mechanism of their actions.

Identification of key genes modules linking diabetic retinopathy and circadian rhythm
Frontiers in Immunology, 2023 BackgroundDiabetic retinopathy (DR) is a leading cause of vision loss worldwide. Recent studies highlighted the crucial impact of circadian rhythms (CR) on normal retinopathy in response to the external light cues.

IEEE Access, 2015 Most genetic networks, such as that for the biological clock, are part of much larger modules controlling fundamental processes in the cell, such as metabolism, development, and response to environmental signals. For example, the biological clock is part

Sleep Timing in Late Autumn and Late Spring Associates With Light Exposure Rather Than Sun Time in College Students [PDF]
, 2019 Timing of the human sleep-wake cycle is determined by social constraints, biological processes (sleep homeostasis and circadian rhythmicity) and environmental factors, particularly natural and electrical light exposure. To what extent seasonal changes in

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
