Toxicokinetic Modeling - an overview ScienceDirect Topics
WebSimilarly, physiological toxicokinetic models are physiological pharmacokinetic models developed to describe and predict the behavior of a toxicant in an animal body; for example, what parts (compartments) of the body a chemical may tend to enter (e.g. fat, liver, spleen, etc.), and whether or not the chemical is expected to be metabolized or … WebFour processes are involved in toxicokinetics: Absorption — the substance enters the body. Distribution — the substance moves from the site of entry to other areas of the body. Biotransformation — the body changes (transforms) the substance into new chemicals (metabolites). Excretion — the substance or its metabolites leave the body. WebResearch Project: Characterizing the uncertainty in the predictions of toxicokinetic models, including predictions based upon in vitro data, requires comparison to in vivo data. This research project works to address the current major sources of uncertainty in high-throughput toxicokinetics (HTTK). folding accordion style
