On the Quantitation of Radiorenograms

Scandinavian Journal of Clinical and Laboratory Investigation, 1971
A functional parameter of the radiorenogram, the uptake ratio, was compared with the bilateral renal clearance of inulin and PAH in a mixed surgical-urological material. For kidneys without signs of obstruction to the urine flow, a close correlation was observed over the whole range of kidney function, which indicated that the uptake ratio of the ...

Quantitative Traits and Quantitative Genetics

2014
In contrast with qualitative or dichotomous traits, quantitative traits are measured using quantitative or semi-quantitative variables and their inheritance is controlled by multiple genes acting independently or in association. Quantitative traits are also influenced to varying degrees by the environment and this explains why they are often designated

Quantitative results

New Directions for Mental Health Services, 2000
AbstractDetailed analysis of information obtained is still under way, but initial trends appear to show stable enrollment, maintenance of minimum service levels, and lower hospital utilization.

Is Quantitative Metallography Quantitative?

1970
While the basic principles of quantitative metallography have been firmly established, the practice of such measurements yields highly variable results. Simple laws define the statistical limitation on any measuring method. Serious errors arise from improper selection and preparation of specimens.

Quantitation of Erythropoiesis

Nature, 1963
IT was not until recently that a method for the quantitative estimation of erythropoiesis became available1. The method introduced requires the application of high doses of radioactive iron, a very stable and sensitive measuring equipment and protracted measurements.

Quantitative PCR

2003
Quantitative PCR recently has become a powerful tool in clinical investigations. Its main areas of application have been the assessment of residual disease after treatment of leukemia and lymphoma, the detection of viral nucleic acids, and the detection of gene amplification or deletion and of aneuploidy (1).The application of PCR as a quantitative ...

Quantitative Cisternography

Acta Radiologica. Diagnosis, 1978
By quantitative cisternography using a stationary detector system with correction for tissue background, an exponential elimination of 131I-HSA from the basal cisterns was demonstrated, allowing calculation of a biologic half time (BHT) of the clearance curve of a satisfactory level of reproducibility. 'Normal' range of BHT was calculated.

Quantitative Epidemiology

Infection Control & Hospital Epidemiology, 1996
Abstract We provide guidance for new practitioners in the vocabulary of modern epidemiology and the application of quantitative methods. Most hospital epidemiology involves surveillance (observational) data that were not part of a planned experiment, so the rubric and logic of controlled experimental studies cannot be applied.

Quantitative Traits

2014
Quantitative traits are phenotypic traits that are determined, jointly with the environment, by many genes of small effect. Most of the directly observable individual characteristics are quantitative traits. Differences in quantitative traits can give valuable signals on existence of separate stock components.

Quantitation of the Nucleus

1990
Known to be the location of the control data which dictate benign or malignant behaviour of the cell (Laskey 1987), the nucleus has been at the centre of the quest for the pathognomic features of malignancy for over a century (Hall and Fu 1985). In practical histopathology, interpretation of the features of nuclear size, shape, density and chromatin ...
