Diurnal variation in prednisolone kinetics

Clinical Pharmacology and Therapeutics, 1983
Plasma concentrations of free and total prednisolone were measured after oral doses at four time points to investigate the possibility of a diurnal variation in the drug's kinetics. There were marked differences in plasma prednisolone concentrations, clearance rates, and bioavailability of both free and total fractions at different times of the day ...

DIURNAL VARIATION IN LOGICAL REASONING

British Journal of Psychology, 1975
Subjects performed two tests of logical reasoning at each of six different times of day. In terms of speed, performance on both tests was found to improve markedly from 08.00 to 14.00 and then to fall off fairly rapidly. Accuracy was found to decrease fairly linearly over the day.

Diurnal Variation in Tennis Service

Perceptual and Motor Skills, 1998
With informed consent, 6 competitive tennis players performed alternate 15 “first” (emphasis-speed) serves and 15 “second” (emphasis-accuracy) serves at 09:00, 14:00 and 18:00 hours. Serve velocity was measured by the digitisation of video footage of each serve. The Hewitt Tennis Achievement Test was employed to measure the accuracy of serve.

Diurnal variations in cardiovascular integration

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1986
Beat-to-beat heart periods and intra-arterial blood pressures were monitored continuously for 18 h in each of six monkeys over periods of several weeks. Means, based on 128-s averages of these functions, were highly correlated during early evening and daytime periods; however, heart period was poorly correlated with blood pressure during the evening ...

The Diurnal Variation of Stroke in Ghana

Tropical Doctor, 1994
In 68 patients presenting with stroke in Ghana a significant ( P <0.001) peak in onsets occurred between 0600 h and 1000 h. There were no significant differences in time of onset between men and women or hypertensive and non-hypertensive patients. Reasons for the peak of onsets are discussed.

Diurnal variation in tardive dyskinesia

Psychiatry Research, 1995
Tardive dyskinesia (TD) is a common movement disorder that is associated with chronic neuroleptic exposure. To better characterize the clinical aspects of TD, we investigated the diurnal pattern of involuntary movements by blindly rating videotaped examinations of patients from the morning shortly after awakening and later in the same afternoon.

Diurnal Variation in Urinary Oxalate

British Journal of Urology, 1977
The diurnal variation in urinary oxalate concentration and output was measured in 10 catheterised males. There was an increase in urinary oxalate concentration and output during the day and evening and an early morning decrease. It is thought that the daytime increase is related to dietary oxalate.

Diurnal variation in corneal thickness

Experimental Eye Research, 1973
Abstract Corneal thickness was measured at three different times of day in rabbits. The rabbit cornea showed a significant diurnal variation regarding thickness. In most cases, the cornea was thickest in the forenoon, and then thinning followed. It usually became thinnest in the afternoon, but sometimes at about noon.
