Peroxidase activity in human granulocytes, inter- and intra-individual variations
Scandinavian Journal of Clinical and Laboratory Investigation, 1977A kinetic method for quantitation of peroxidase activity ('myeloperoxidase', E.C. 1.11.1.7.) in human granulocytes has been evaluated. The enzymic activity was determined at 37 degrees C, PH = 7.0. Substrates: 2-methyxo-phenol (1.25 mmol/l) and H2O2 (0.1 mmol/l). When applied on granulocytes from solitary blood samples from healthy, normal subjects the

Intra‐individual variations in acute and cumulative skin irritation responses
Contact Dermatitis, 2001It is well‐known that humans show a wide range of variation in skin reactivity to irritant chemicals. This has been established through population studies, through the examination of inter‐subject variability, and (to a limited extent) through studies of skin site variation in response within subjects.

Long-term intra-individual variation of platelet parameters.
Medical laboratory sciences, 1989Mean platelet volume, platelet count and platelet distribution width were determined in eight male subjects at monthly intervals over a 4-6 month period. Measurements were made on a Coulter S Plus VTM exactly 15 min and 2 h after blood collection. Long-term intra-individual variability for mean platelet volume showed a mean coefficient of variation (CV)

Inter and Intra Individual Variation of Blood Glucose Levels
1985The most commonly used diagnostic aid for early diabetes mellitus is the oral glucose tolerance test. The test, however, is subject to considerable variation due to differences in individual rates of gastrointestinal absorption of the glucose challenge. This problem is accentuated in the pregnant woman; yet pregnancy is the ideal period during which to

Intra-individual variation of plasma lipids and lipoproteins in prepubescent children
European Journal of Applied Physiology, 1999Estimates of the average intra-individual biological variability for plasma lipids and lipoproteins differs substantially among published studies. Moreover, this topic does not appear to have received consideration in exercise and health literature with normal, healthy children as subjects.

Inter- and intra-individual variations in normal urinary glycine betaine excretion
Clinical Biochemistry, 2007To establish whether normal human subjects excrete glycine betaine at a constant rate.Urine was collected from ten normal healthy male subjects for 14 days, during which fluid intake was systematically varied from 3 L per day. Glycine betaine, sorbitol and creatinine excretions were estimated per day and as millimole per mol creatinine.The intrasubject

Using intra‐individual variation in shrub architecture to explain population cover
Oikos, 2014Plant architecture is related to the performance of long‐lived plants; its role in promoting species coexistence and in successional patterns is now widely recognized. However, because plant architecture involves branching processes, it is highly variable at the intra‐specific level.

Intra-individual variation and evolution of modular structure in Draba plants
Biosystems, 2014We studied the evolution of quantitative traits related to shoot system architecture in a large genus Draba (Brassicaceae) making emphasis on the dynamics of relationship between individual and intra-individual variation. The results suggest that selection leading to origin of different life forms arises mainly from a necessity of moderation of the non-

Inter- and Intra-Individual Variations during the Progress of Motor Learning
Research Quarterly. American Association for Health, Physical Education and Recreation, 1968Abstract The effects of practice and the passage of time on individual differences (true-score variance) and intra-individual variation were investigated. One hundred and twenty male university students were tested on a Koerth type pursuit rotor. One group was tested on six days spaced over a three-week period.
