Assessment
Unaided Work:
Attendance of lectures is free, participation in 2 seminars, practical works and laboratory works is obligatory. The tasks of the study course are: 1) To give an idea of ​​the active forms of oxygen and nitrogen and the formation and function of radicals; 2) To provide knowledge about antioxidants, the necessary trace elements, their role in the norm, changes in risk groups, as well as in cases of common diseases and pathological conditions; 3) To acquaint with the analytical equipment used in laboratory practice and modern, standardized analytical methods, as well as to inform about the quality control of analyzes regulated by the existing legislation.
Assessment Criteria:
For obtaining credit points is required participation in all seminars (40%), laboratory work (15%) and practical work (15%), as well the answers to the final test question must be hand in (30%).
Final Examination (Full-Time):Exam
Final Examination (Part-Time):Exam
Learning Outcomes
Knowledge:After successful completion of the study course the student will be able to: 1) To tell about the formation and activity of active forms of oxygen and nitrogen and radicals. 2) To define knowledge about antioxidants, necessary microelements, their role in the norm, changes in risk groups, as well as in cases of more common diseases and pathological conditions. 3) To understand the analytical equipment used in laboratory practice and to interpret modern, standardized analytical methods, to inform about the quality control of analyzes regulated by the existing legislation.
Skills:As a result of the course the student will apply the acquired theoretical knowledge in practice: Learning to explain: - Possibility of formation of oxidants in the body; - Changes in antioxidants and trace elements in risk groups, major diseases and pathologies; -Will be able to evaluate laboratory equipment and explain the results. -Will be able to evaluate quality control of regulatory analyzes.
Competencies:Upon successful completion of this course, students will gain an understanding of free radical biochemistry, pro-oxidative and antioxidant processes in the body and their relationship to various pathological conditions and diseases, as well as prepare for independent research in radical biochemistry.
