(Mary Ann Liebert, Inc./Genetic Engineering News) Integrated approaches that avoid the use of animals to assess the toxicity of inhaled materials may include a computational model to screen for chemical reactivity, a human tissue-based assay to predict the absorption of a chemical into the respiratory tract, and other types of advanced systems based on in vitro and in vivo respiratory biology.

Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism. Examples of genetically engineered (transgenic) organisms currently on the market include...
An assay is an analytic procedure for qualitatively assessing or quantitatively measuring the presence or amount or the functional activity of a target entity. This can be a drug or biochemical substance or a cell in an organism or organic sample. ...
