Chemical Safety Testing On Animals May Not Be Valid For Humans, Recent Study FindsSince Congress mandated testing of new medicines and chemicals on animals back in 1937, billions of laboratory animals have been subjected to a vast number of chemicals and medicinal compounds R…PlanetSave...
Shortcomings of LD50-values and acute toxicity testing in animals. Abstract The author argues that the standard practice of determining an LD50 with 95% confidence limits is a waste of animals since the extra statistical p... A Rowan - 《Acta Pharmacologica Et Toxicologica》 被引量: 10发表: ...

Since the seminal work of Vintheret al.55, inferences about the color patterns of fossil animals rely mainly on melanosome morphology13, in spite of other studies that indicate the lack of correlation between melanosome shape and their melanin content56,57. While the connection between shape and...
Testing consistent with the Organisation for Economic Co-operation and Development (OECD) test guideline for eye irritation/corrosion, which specifies 3 animals, can also be submitted to US agencies. However, current FHSA regulations do not provide criteria to classify results from 3-animal tests. ...
In all, 134 substances were analyzed in the monitoring plan; 35 substances were examined in the surveillance and enforcement testing program, and 27 substances were investigated in exploratory projects. The overall trend of violation rates gradually decreased over the past decade. Pesticides were not ...
The practical application of this model is demonstrated, using an example taken from the reports of the Danish progeny testing stations. Assuming that the rate of protein deposition in the body is a highly inheritable trait it is also shown how the genotype and the level of feeding jointly ...

— What you also need is very detailed characterization, testing especially the compound for selectivity against as many proteins as possible. Selectivity is super important. We think a good probe should be at least 30-fold more selective compared to proteins in the same family. Broader profiling...
Blood lactate (mmol/L) and glucose (mg/dL) concentrations were measured in captive wood bison (Bison bison athabascae) restrained for disease testing and health, pending reintroduction into Alaska. The majority of the herd (n = 70) were restrained in a hydraulic squeeze chute, though the larg...
