Course objectives
The aim of the course is to acquaint students with the causes of the development of selected disorders and diseases, especially so called civilization diseases, such as cardiovascular, cancer, inflammation, allergies, stress and psychological disorders, including approaches and methods of their research. It is focused especially to the impact of environmental factors on human health with an emphasis on the role of lifestyle, environment and specific nutrients and the use of knowledge in the prevention of diseases. Students will also learn about the existence and regulation of the body as a hierarchical system, essential processes necessary to maintain its normal functions, and factors that may interfere with these functions.
Learning outcomes
At the end of the course students should be able to: recognize the most harmful environmental factors and their impacts on human health including possibilities of disease prevention; describe specific dietary factors and their association with etiology of some serious so-called civilization diseases, such as cardiovascular diseases, cancer, allergies or stress; understand the view of the organism as a hierarchical system and what are the basic processes necessary for maintenance of its homeostasis; interpret and use knowledge of environmental factors influencing human health and of possibilities of disease prevention; explain recent results of epidemiologic and scientific studies of given topic; learn the ability to elaborate and present assigned topic.
Syllabus
  • Causes of initiation and promotion of civilization diseases - genetic predisposition, life style. Type of studies (epidemiological, clinical, and experimental studies, population screening ), occurrence of cancer (in the Czech Republic, in the world), source of information - yearbook of health in ČR, SVOD, NOR. Problems of specific types of studies. Carcinogenesis - main cancer promotion factors, genetic and non-genetic factors, endogenous factors - the role of hormones. Cardiovascular diseases, carcinogenesis and life style (smoking, diet, physical activities). Harmful environmental factors - radiation (ionizing, non-ionizing), chemicals and xenobiotics (heavy metals, aromatic hydrocarbons, PCBs, dioxins, pesticides, drugs etc.). Diet - energy balance, effects of high-glycide and high-fat diets, specific dietary lipids – fibre and butyrate, fatty acids, n-3 and n-6 polyunsaturated fatty acids and their importance for health (cardiovascular diseases, foetal development, depression and neurodegenerative diseases, cancer). Fruits and vegetables and other beneficial food components. Chemoprevention - risk assessment, targets for decrease of risk and mortality, anticancer factors. Contemporary system of detection of carcinogenic effects of compounds; Genotoxicity (mutagenic effects) – mutagenicity tests; Problems of detection of non-genotoxic carcinogens; long-term test with laboratory animals, alternative short-term tests - transformation test, changes of proliferation and apoptosis in tissues, GJIC changes, detection of specific biomarkers (specific cell enzyme and receptors activities); Models of carcinogenesis - studies of initiation and promotion effects - skin, liver, bladder, kidney; causes of different sensitivity of cells, tissues and organisms to carcinogens; Risk assessment - dose-response curves, threshold values, the effects of mixture of compounds (additivity, synergism, antagonism). Importance of experimental ecotoxicology - perspectives, association with experimental and predictive oncology. Prevention, diagnostics and treatment of cancer. Experimental, epidemiologic and clinical studies, population screening, diagnostic markers. Therapy, paliative care; Predictive oncology - detection of specific markers, comparison of methods and interpretation of measured parameters, data management and data interpretation - significance of multidimensional statistical analyses. Homeostasis, health and disease - basic terms, short introduction to the theory of systems. Negative and positive feedback - significance for homeostasis, homeostasis on the cell, tissue and system levels. Organism as hierarchic system, cooperation of nervous, endocrine and humoral systems. Causes of cardiovascular diseases. Causes of allergy and inflammation. Stress - causes and consequences. Prevention of functional damage and diseases vs. therapeutic possibilities.

Teaching methods
Basic lectures by teachers and associated discussion. Study of own selected research topic and its presentation with class discussion.
Assessment methods
Attendance of the lectures is not mandatory but recommended for understanding the topics, discussion with other students and creating and expression student's own opinion. Prerequisite for the course completion is preparation of about 10 min presentation for class colleagues and discussion of assigned topic. The final examination is based on written exam evaluated by the teacher. Students must answer minimally 10 from 20 questions covering the topics presented in the lectures.
