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.

Combining Multivariate Bioassays
Biometrics, 1986Linear multivariate theory is applied to the problem of combining several multivariate bioassays. Results are an asymptotic test of the hypothesis of a common log relative potency; the maximum likelihood estimator of the common log relative potency; and an exact and asymptotic confidence interval estimator for log relative potency.

Bioassays constitute a unique approach to determine the functional aspects of gonadotropins. Indeed, these highly complex glycoprotein hormones, including pituitary lutropin (LH) and follitropin (FSH), are heterogeneous in terms of both peptidic and carbohydrate moieties, and, as a consequence, the bioactivity of the different molecular forms often ...

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 ...

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).

Cold Spring Harbor Protocols, 2023
Insecticide bioassays are frequently used to measure levels of insecticide resistance in mosquito populations, examining the ability of mosquitoes to survive exposure to insecticides. Laboratory bioassays measure insects’ responses to insecticides in resistant (field) populations and laboratory susceptible strains using serial doses or concentrations ...

Multivariate Bioassay, Combination of Bioassays, and Fieller's Theorem
Biometrics, 1986In 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.

Tradescantia micronucleus bioassay
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1994Four coded chemicals, azidoglycerol (AG), N-methyl-N-nitrosourea (MNU), sodium azide (NaN3), and maleic hydrazide (MH), were tested with the Tradescantia micronucleus (Trad-MCN) bioassay by five independent laboratories from five different countries. The purpose of this international collaborative study was to evaluate four plant bioassays, of which ...

Human Pathology, 1984
Bioassay of hormones has a small but important role in defining the physiologic status of selected patients in whom immunoassay results do not correlate with clinical signs and symptoms. This article reviews three sensitive bioassays for hormones, which are based on 1) stimulation of adenylate cyclase in membrane preparations, 2) cytochemical changes ...
