Arsenic is a worldwide environmental pollutant that generates public health concerns. Various types of cancers and other diseases, including neurological disorders, have been associated with human consumption of arsenic in drinking water. At the molecular level, arsenic and its metabolites have the capacity to provoke genome instability, causing al...
Article
Amorphization of active pharmaceutical ingredients (APIs) and the preparation of solid dispersions are strategies that can be synergized to improve the solubility of oral drugs. Immiscibility between an API and a carrier in the molten state that could be perceived as a problem in the preparation of solid dispersions, may actually introduce an advan...

Print workers are exposed to organic solvents, of which the systemic toxicant toluene is a main component. Toluene induces expression of cytochrome P450 2E1 (CYP2E1), an enzyme involved in its own metabolism and that of other protoxicants, including some procarcinogens. Therefore, we investigated the association between toluene exposure and the CYP...
