A new numerical method for solving the inverse problem of internal dosimetry is described. The new method uses Markov Chain Monte Carlo and the Metropolis algorithm. Multiple intake amounts, biokinetic types, and times of intake are determined from bioassay data by integrating over the Bayesian posterior distribution. The method appears definitive, but its application requires a large amount of...

A filter paper bioassay was developed for testing the efficacy of nematodes and other agents for control of Diaprepes abbreviatus larvae. Surfactants, with and without Steinernema riobravis, were screened first in the filter paper bioassay and then in a potted citrus seedling study. The results of the two assays were in agreement on the relative merits of the compounds tested. Surfactants incre...

Tumor detection can be carried out via the detection of proteins, such as p53, which is known to play vital role in more than 50% of all cancers affecting humans. Early diagnosis of tumor detection can be achieved by decreasing the lower detection limit of p53 bioassays. Microwave-accelerated bioassay (MAB) technique, which is based on the use of circular bioassay platforms in combination with ...

Bioassay is considered to be a relatively new technique, known the scientific community for about 30 years. This article covers method of determining total toxicity by bioassay using infusoria. Microorganisms from 4 genera can used technique: Tetrahymena, Stylonicha, Paramecium, Colpoda. The in food and feed. Advantages this comparison with traditional methods are given. results patent search o...

Aims: Entomopathogenic nematode (EPN) and its symbiotic bacterium are used worldwide as microbial control agents. Toxins from EPN bacteria were isolated provided basis for using this potential resource biocontrol agent against vegetable diseases pests.
 Study Design: The toxins extracted 28 strains of associated with entomopathogenic nematodes. insecticidal activity antibiotic pests determ...
