Circadian rhythms in thrombosis and atherothrombotic events [PDF]

open access: yesFrontiers in Bioscience-Landmark, 2022
Biological circadian rhythms in living organisms are regulated by molecular clocks. Several of these clocks are present in blood vessels, peripheral tissues, and immune cells.

Circadian control of isoprene emissions from oil palm (Elaeis guineensis) [PDF]

open access: yes, 2006
The emission of isoprene from the biosphere to the atmosphere has a profound effect on the Earth's atmospheric system. Until now, it has been assumed that the primary short-term controls on isoprene emission are photosynthetically active radiation and ...

Circadian rhythms [PDF]

open access: yesBrain Research Reviews, 1993
Circadian rhythms are a ubiquitous adaptation of eukaryotic organisms to the most reliable and predictable of environmental changes, the daily cycles of light and temperature. Prominent daily rhythms in behavior, physiology, hormone levels and biochemistry (including gene expression) are not merely responses to these environmental cycles, however, but ...

Circadian rhythms

open access: yes, 2020
Circadian rhythms are endogenous, near 24-hour oscillations that underlie nearly all facets of our health and behavior. The daily cycle of sleep and wake is the most conspicuous circadian-influenced behavior in humans.

Novel mechanisms operating in the central pacemaker and in the light-synchronization pathway of Drosophila’s circadian clock [PDF]

open access: yes, 2011
PhDMost organisms display circadian rhythms of approximately 24 hours in many aspects of their physiology and behaviour. The synchronization between their internal rhythm and the environmental light-dark cycles is essential for an organism’s survival ...

The TIME FOR COFFEE gene maintains the amplitude and timing of Arabidopsis circadian clocks [PDF]

open access: yes, 2003
Plants synchronize developmental and metabolic processes with the earth's 24-h rotation through the integration of circadian rhythms and responses to light.

Aging and circadian rhythms [PDF]

open access: yesCurrent Opinion in Insect Science, 2015
Circadian clocks are cell-autonomous molecular feedback loops that generate daily rhythms in gene expression, cellular functions, physiological processes and behavior. The mechanisms of circadian clocks are well understood in young fruit flies Drosophila melanogaster, but less is known about how circadian system changes during organismal aging. Similar

Clockwork green – the circadian oscillator in Arabidopsis [PDF]

open access: yes, 2006
Schöning JC, Streitner C, Staiger D. Clockwork green – the circadian oscillator in Arabidopsis. Biological Rhythm Research. 2006;37(4):335-352.Although rhythmic leaf movement in a higher plant was the first physiological process recognised to be under ...

Adult Circadian behavior in Drosophila requires developmental expression of cycle, but not period [PDF]

open access: yes, 2011
Circadian clocks have evolved as internal time keeping mechanisms that allow anticipation of daily environmental changes and organization of a daily program of physiological and behavioral rhythms.

An adipokine feedback regulating diurnal food intake rhythms in mice

open access: yeseLife, 2020
Endogenous circadian clocks have evolved to anticipate 24 hr rhythms in environmental demands. Recent studies suggest that circadian rhythm disruption is a major risk factor for the development of metabolic disorders in humans. Conversely, alterations in
