Assessment
Unaided Work:
Independent study of theoretical topics using other sources, such as scientific books, publications. In order to evaluate the quality of the study course as a whole, the student must fill out the study course evaluation questionnaire on the Student Portal.
Assessment Criteria:
Participation in practical lessons, solving tasks. In the final exam, a scientific work, using the acquired knowledge, on problem studies.
Final Examination (Full-Time):		Exam (Written)
Final Examination (Part-Time):
Learning Outcomes
Knowledge:		Upon successful completion of the study course, the student will be able to: 1) Tell about the formation and activity of active oxygen and nitrogen species and radicals. 2) Define knowledge of antioxidants, essential trace elements, their role in the norm, changes in risk groups, and in more common diseases and pathological conditions. 3) Understand the analytical equipment used in laboratory practice and interpret modern, standardised analytical methods, inform about the quality control of analyses regulated by existing legislation.
Skills:		Having mastered the study course, the student will apply the acquired theoretical knowledge in practice: They will be able to explain: • The formation of oxidants in the body; • Changes in antioxidants and trace elements in risk groups, in cases of common diseases and pathologies. • The student will be able to evaluate the equipment used in laboratory practice and explain the obtained results. • The student will be able to evaluate the quality control of analyses regulated by legislation.
Competencies:		On successful completion of this course, students will understand free radical biochemistry, pro-oxidative and antioxidative processes in the body, and the links between these processes and various pathological conditions and diseases, and will be prepared for independent research work in the radical biochemistry.
