Teacher:

Milan R. Nikolić, Ph.D.
associate professor, Faculty of Chemistry, Studentski trg 12-16, Beograd

Assistants:

Hours of instruction:

Weekly: five hours of lectures + three hours of study research work

Goals:

Deepening knowledge of xenobiotics metabolism, their bioinactivation and bioactivation; free radical toxicology; interactions of reactive intermediates with biomolecules and implications of their toxicity; methods of identification, isolation and product determination of these interactions; the most significant classes of toxic substances and the biochemical basis of their effects on organ function.

Outcome:

The acquired knowledge will enable students to solve problems related to the testing of xenobiotic metabolism, to examine the toxic effects of foreign substances, to identify markers of toxic effects and to develop methods for their determination.

Teaching methods:

Lectures and seminar paper.

Syllabus:

1. Enzyme systems involved in xenobiotic metabolism; Distribution in tissues, distribution in species, hormonal regulation, expression; Role in the activation and detoxification of foreign substances.
2. Isolation and characterization of xenobiotic-modified biomolecules; Identification of DNA adducts; Chemical mutagenesis, carcinogenesis and teratogenesis.
