How To Say Carcinogenicity

the futility of) trying to predict carcinogenicity of

The challenge is to predict the carcinogenicity of chemicals based on structural information only I have only tackled such predictions for bioessays involving male rats As we currently do not know the true predictions for the testset all we can say is that one of the models supplied by us seems to be optimal over some subrange of the ROC

Carcinogenicity

Carcinogenicity induced by phase I and phase II drug-metabolizing enzymes (DMEs) involves the following: certain procarcinogens are metabolized and activated into carcinogens by phase I CYPs or phase II GSTs and the resultant carcinogens bind with biological macromolecules this is an initiation step of carcinogenicity Conversely multidrug

The hazards of hazard identification in environmental

Hazard identification is a major theme and challenge for environmental epidemiology often fueling heated debate as the recent [] and ongoing [] case of glyphosate carcinogenicity shows Debate arises in the first place because the hazard identification process is inherently complex in many of its components particularly those that depend much more on scientists' judgment than on procedures

Predicting the Carcinogenicity of

Regulatory agencies currently rely on rodent carcinogenicity bioassay data to predict whether or not a given chemical poses a carcinogenic threat to humans We argue that it is always more useful to know a chemical's carcinogenic potency (with confidence limits) than to be able to say only qualitatively that it has been found to be a carcinogen
