Diurnal variation of asthma

British Journal of Diseases of the Chest, 1977
We have studied possible aetiological factors in the large diurnal variation in peak expiratory flow rate seen in some asthmatics. This phenomenon occurred in both atopic and non-atopic patients. It could not be attributed to recumbency in bed at night or to allergy to the house dust mite in bedding.

DIURNAL VARIATION IN DEPRESSION—IS IT THERE?

THE JOURNAL OF NERVOUS AND MENTAL DISEASE, 1975
In this paper we present the results of an investigation designed to measure diurnal variation of mood in a group of unipolar depressives using a sensitive self-assessment inventory and a behavioral measure of the depth of depression. Both measures correlate well with the Hamilton Rating Scale which was designed to quantify depression during a ...

Diurnal Variation of the Fibrinolytic System

Thrombosis and Haemostasis, 1988
AbstractTo elucidate which component(s) of thei fibrinolytic system is (are) responsible for the diurnal variation of fibrinolytic activity we have studied several parameters of this system in 8 healthy male volunteers during a period of. 24 h. Blood was collected at 8 a. m., 10 a. m., 12 a. m., 4 p.m., 8 p.m. and 8 a. m. next morning.

DIURNAL VARIATION IN CYCLING KINEMATIC

Medicine & Science in Sports & Exercise, 2003
Physiological and biomechanical constraints as well as their fluctuations throughout the day must be considered when studying determinant factors in the preferred pedaling rate of elite cyclists. The aim of this study was to monitor the diurnal variation of spontaneous pedaling rate and movement kinematics over the crank cycle.

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 of height in children

Pediatrics International, 2005
Abstract  Background : Diurnal variation of height is largely ignored in the assessment of growth in children. Diurnal decrease in stature may effect the reliability of height measurement. In this study, the degree of differences in daily height measurement were evaluated. Methods : A total of 478 children,

Diurnal variation of radon progeny

Journal of Environmental Radioactivity, 2007
The diurnal variation of the gross alpha (alpha) radioactivity in the air near the ground and the gamma (gamma) radioactivity emitted from the ground have been monitored in North-eastern Greece. Meteorological information comprising air temperature and humidity has been simultaneously recorded.

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.

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. A similar diurnal pattern of stroke has been described in

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 ...
