BACKGROUND Myocardial infarction, stroke, and sudden death undergo diurnal variation. Although genes relevant to hemostasis and vascular integrity undergo circadian oscillation, the role of the molecular clock in thrombotic events remains to be established. METHODS AND RESULTS A diurnal variation in the time to thrombotic vascular occlusion (TTVO) subsequent to a photochemical injury was obse...
[1] This study analyzes diurnal and seasonal variations of snow albedo at four Baseline Surface Radiation Network stations in the Arctic and Antarctica from 2003 to 2008 to elucidate similarities and differences in snow albedo diurnal cycles across geographic zones and to assess how diurnal changes in snow albedo affect the surface energy budget. At the seasonal scale, the daily albedo for the ...
background: temporal variation of stroke onset is suggested in some studies contained somewhat varieties. it is proposed that some predisposing changes occur in some ascertained times consequently resulted in stroke occurrence in some special times. objective: to determine the circadian and circaseptan variation of stroke onset. materials and methods: this cross sectional study was conducted fr...
