A pharmacologist's training encompasses the entire spectrum of the drug discovery process: identification and validation of targets, study of preclinical animal models, determination of dosing schedules, and testing of toxicity in clinical trials.
In addition to testing of toxicity on cellular level, we decided also to investigate in greater detail the molecular mechanisms of action of studied complexes using the cellular model system based on the LPS-activated respiratory burst in phagocytes and its effect on the inflammatory cytokine expression.
In addition to reducing the need for animal testing of new drugs, environmental and drug toxicities tests currently performed on rodents can be replaced with tests of toxicity in ESC-derived cells.
This functional approach is also promising for the generation and testing of toxicity hypotheses (Donald et al. 2002; Zhang et al. 2002) or the identification of perturbed pathways (Wang et al. 1999; Zimmermann et al. 2003).
We chose the yeast Candida albicans as a fungal model to test for toxicity of the surfactants examined in this work.
A non-invasive test of mitochondrial toxicity is needed to assess toxicity and optimise HIV treatment strategies.
In an unusual test of the toxicity of particles filtered from the same spots at different times, agency scientists found that substances collected near a Utah steel mill when it was running were more harmful to the lungs of volunteers than material captured when the plant was dormant.
Following acclimatization, short term test of acute toxicity over a period of 96 hrs was performed on the fishes following the renewal of bioassay.
A short-term test of AgNP toxicity on embryos and sac-fry stages (larvae) was conducted with fertilized eggs for 14 d, as outlined in OECD Technical Guide 212 [ 23].
Physical examination, laboratory tests and assessment of toxicity were performed weekly during treatment.
The liver is the primary organ for detoxification, defending living organisms against toxic agents; hence, it is often used in tests of the toxicity of nanomaterials [35].
