parahaemolyticus challenge (bioassays one and two), a bioassay (4 d) was conducted to determine the [LC.sub.50] (lethal concentration, 50%) using animals weighing 528 [+ or -] 31.7 mg and 452 [+ or -] 50 mg.

The direct result of these efforts is a rapidly growing amount of in vitro bioassay data being generated for thousands of chemicals and stored in databases accessible to public users, allowing for new statistical and computational techniques to be developed.

The method used most often worldwide is the mouse bioassay (MBA), where an extract of shellfish is injected intraperitoneally into a number of mice and death is the endpoint that determines whether the sample is safe to consume or not (Garthwaite, 2000; Stewart and McLeod, 2014).

Following on our pioneering work on cosmetic human growth hormone and its efficacies on the intact skin, Regeron commercialized tens of cosmetic growth factors and developed their accompanying bioassay systems.

PESHAWAR -- Ms Sadia, PhD Research scholar has submitted her thesis on ' PHYTOCHEMICAL EVALUATION AND BIOASSAY SCREENING OF BREBERIS LYCIUM ROYLE' to University of Peshawar, in partial fulfillment of the requirement for the award of Doctor of Philosophy (Ph.D ) in Biotechnology.

Traditionally, insecticide susceptibility tests in mosquito populations use the bioassay methodologies recommended by the World Health Organization (WHO), where mosquitoes are exposed to impregnated papers with known concentrations of an insecticide during a given time (WHO 2016).

An activity-based bioassay may serve this purpose, by functioning as a first-line screening tool, complementing the conventional targeted and untargeted analytical methods.

In the article titled "Establishment of a Consistent L929 Bioassay System for TNF-[alpha] Quantitation to Evaluate the Effect of Lipopolysaccharide, Phytomitogens, and Cytodifferentiation Agents on Cytotoxicity of TNF-[alpha] Secreted by Adherent Human Mononuclear Cells" [1], the figures were missing due to a publisher error.

A large number of insects were required to perform the bioassays. For the pathogenicity and interaction experiment, a total of 1000 third-instar larvae of P vetula were collected in the field in Villa de Ayala, Morelos, Mexico, placed individually in 30-ml plastic cups covered with plastic lids, transported to the laboratory, and maintained at 25 [+ or -] 1[degrees]C for 7d before the bioassay.

ABSTRACT: A series of biphenyl derivatives were synthesized and evaluated for brine shrimp lethal bioassay and antibacterial activities.
