Bioassay of kinship

Theoretical Population Biology, 1971
Abstract Kinship between two population I and J , defined as the probability of identity by descent for a random pair of alleles from I and J , can be estimated by bioassay of phenotypes, names, metrics, and gene frequencies, and can be predicted from genealogy and demography by both deterministic and Monte Carlo methods.

BIOASSAY OF RELAXIN

Endocrinology, 1953
IN 1926 Hisaw first demonstrated experimentally the relaxation of the pelvic ligaments of guinea pigs during estrus following the injection of blood serum from pregnant rabbits. Later work indicated a specific hormone, designated as relaxin, was responsible for the looseness of the symphysis pubis, since the effect was also observed following injection

Multivariate bioassay

Controlled Clinical Trials, 1984
Linear multivariate theory is applied to \textit{A. Vølund}'s [ibid. 36, 225-236 (1980; Zbl 0436.62092)] multivariate bioassay problems resulting in more powerful tests of hypotheses, a simple ML estimator of relative potency, and a Fieller-like confidence interval.

Bioassays with a microphysiometer

Nature, 1990
By sensitively monitoring the metabolic rates of living cells, a novel instrument detects cellular responses to stimuli as diverse as ligand-receptor binding and toxic chemicals.

Multivariate Bioassay

Biometrics, 1980
In a multivariate bioassay the response variable is r-dimensional and the dose variable is one-dimensional. Thus, the graph of the dose response relation is a curve in the (r+1)-dimensional space. The similarity requirement for a test and a standard is divided into two parts: (i) a condition of marginal similarity corresponding to the usual similarity ...

Multivariate Bioassay, Combination of Bioassays, and Fieller's Theorem

Biometrics, 1986
In this paper alternative methods for estimating the relative potency, its confidence intervals, and testing for proportionality are developed for multivariate bioassays. The test and estimate are based on the smaller characteristic root and the corresponding characteristic vector of a 2 X 2 matrix.

Cytokine Bioassays

2003
Cytokines are important mediators in inflammation, and play a key role in inflammation induced by Gram-negative bacteria. Cytokines are released into serum during different pathological conditions, such as meningococcal disease, and the cytokine levels in serum seem to correlate with fatal outcome of septic shock (1-3).

A Bioassay for Mefloquine

The Journal of Parasitology, 1992
A bioassay method that allows for the estimation of serum concentrations of mefloquine is presented. Concentrations obtained by bioassay and high performance liquid chromatography showed a good correlation. This bioassay should be helpful in assessing prophylactic/treatment failures to mefloquine under field conditions.

The bioassay of gibberellins

Planta, 1966
A bioassay is described which is dependent upon the fact that gibberellin induced α-amylase release from barley half-seeds is proportional to the logarithm of gibberellin concentration applied. This bioassay has been successfully applied to the estimation of gibberellin-like substances in plant extracts.

The Meaning of Bioassay

Biometrics, 1965
The generally accepted practices of biological assay, at least in so far as these are concerned with quantitative estimation, are contained within the concept of dilution assays (Finney [1964]; Jerne and Wood [1949]). In an analytical assay, each test preparation is regarded as a dilution of the standard preparation with a totally inert diluent.
