Phasic pain demonstrates significant diurnal variation in rats. Angiotensin II modulates pain transmission and the diurnal variation in nociception in several rodent pain models. The participation of AT2 receptors in the diurnal regulation of nociception is not yet elucidated. In the present study we investigated the effects of selective peptide AT2 agonist CGP 42112A and the nonpeptide AT2 rec...

Exaggerated postprandial increase in blood glucose has been postulated to be associated with cardiovascular injury. The concentration of blood glucose is altered by glucose absorption from peritoneal dialysis (PD) fluids. In PD patients, we used continuous blood glucose monitoring (CGM) to analyze diurnal variations in blood glucose. Diurnal blood glucose was determined in 10 diabetic PD patien...

This investigation was undertaken in normal subjects to define the relationship between the intensity of exercise and magnitude of fibrinolytic response and to examine the effect of diurnal variations on the exercise response. Fibrinolytic activity was measured on fibrin plates and expressed as mm2. Diurnal variations occurred with lowest activity at 8:00 AM (mean, 66 mm), and peak activity bet...

Previous reports indicate that hypothalamic growth hormone-releasing hormone (GHRH) promotes sleep and is involved in sleep regulation. The aim of our experiments was to determine whether the GHRH and somatostatin contents of the rat hypothalamus have diurnal variations and whether they are altered by sleep deprivation (SD). Hypothalamic samples were collected at 10 time points during the 24-h ...

abstract  introduction: hypertension is a very common cardiovascular disease with extensive effects on body organs. this study was conducted to compare the extent of target organ damage in hypertensive patients with and without significant nocturnal fall in blood pressure (dippers and non-dippers, respectively). methods: one-hundred patients with recently diagnosed hypertension underwent 24-hou...

milk samples from high and low milk producer holstein cows, were obtained during the morning and afternoon milking over a one week period. overall, 1064 samples were tested within 14 times sampling in urmia, iran. milk macro-mineral concentrations in the morning milking and in low producers were greater than in the afternoon and in high producers. the highest and lowest concentrations were obse...

We present for the first time characteristics of upper atmospheric horizontal winds over Korean Peninsula. Winds and their variability are derived using four-year measurements by Korea Astronomy Space Science Institute (KASI) meteor radar. A general characteristic zonal meridional is that they exhibit distinct diurnal seasonal variations. Their changes indicate sometimes similar or different pe...

Position and intensity data from the International Best Track Archive for Climate Stewardship (IBTrACS) are combined with global, gridded precipitation estimates from the Tropical Rainfall Measuring Mission (TRMM)Multisatellite PrecipitationAnalysis (TMPA) for the period 1998–2013 to study the diurnal cycle of precipitation in tropical cyclones. The comprehensive global coverage and large sampl...
