Some of these may involve increased exposure to allergens at night, cooling of the airways, the reclining position, or hormone secretions that follow a circadian pattern.

The circadian patterns of cardiovascular disease have led researchers to new insights about the numerous chemical and hormonal events that precipitate heart attacks and strokes.

Here we report that a mouse homologue of nocturnin is expressed in a circadian pattern in multiple tissues including retina, spleen, kidney, heart and liver.

By and large, though, the study of circadian patterns of disease is still in its infancy, under study in the laboratory but not yet incorporated into medical practice.

Activity is scattered randomly over the 24 hours of the day; aside from avoidance of intense light, no regular circadian patterns are apparent.

You know your particular circadian pattern requires at least seven hours of solid sleep.

Several studies have indicated that pineal melatonin feeds back on SCN rhythmicity to modulate circadian patterns of activity and other processes.

Lastly one may note the role played by the nervous system in controlling circadian behavioural patterns.

A: The circadian pattern of RLS has nothing to do to with the time you went to bed or when you got your hours of sleep.

In this model called a "direct coupling" the two cycles share a key protein whose expression exhibits a circadian pattern.
