Additionally, estrogen-induced tumor induction may involve receptor-mediated cell proliferation with tumor initiation by genotoxic and mutagenic events. Several steps are potentially mutagenic, such as exposure to high cytosolic concentrations of ethylene glycol, and the extreme dehydration that is a requisite for vitrification. This is the first quantitative estimate of the mutagenic effect of cryopreservation on the germ line of a metazoan. Moreover, where hybrid dysgenesis and mutagenic agents result in similar yet quantitatively variable genetic aberrations, accurate correlations are difficult to determine. Reports of hazardous chemical exposures to both male and female workers and related carcinogenic, mutagenic and now teratogenic effects are ever-increasing. Such protection will necessarily have reduced the exposure of bacteria to the potentially mutagenic ultraviolet and other radiation. This agent is a well-known carcinogen with conflicting indications of its mutagenic activity. Before cryopreserved embryos can be used for such studies, it is first necessary to show that cryopreservation is not mutagenic. A number of studies have shown that interactions between mutagenic chemicals and trematode infections can increase the risk of tumour development. Such resistance functions inhibit the uptake of drugs, inactivate the drugs before their interaction with cellular targets or repair lesions caused by the toxic or mutagenic effects of the drugs. Thus, our data suggest that the two genotypes may differ in their mutation rates, but provide no evidence that cryopreservation or storage of embryos is mutagenic. Other than tests for various genotoxic endpoints, including mutagenic and related responses, there has not been cross-agency acceptance of tests based upon in vitro and lower life forms. These oils contain certain quantities of polycyclic aromatic hydrocarbons, which are classified as carcinogenic, mutagenic and reprotoxic substances, as well as persistent organic pollutants. From Europarl Parallel Corpus - English I am thinking in particular of carcinogenic, mutagenic or toxic substances that are known to be harmful.
