The scientific monograph focuses on the characteristics of free radicals, reactive oxygen and nitrogen species, oxidative stress, and its impact on various diseases. A significant portion is dedicated to antioxidants, their classification based on multiple criteria, the characteristics of selected antioxidants in terms of their functions, manifestations of their deficiency and excess, and the overall antioxidant capacity of the body.

A special section is devoted to enzyme-based antioxidants, natural sources of antioxidants in the form of vitamins, trace elements, flavonoids, polyphenols, and coenzyme Q10. To provide a clearer understanding of antioxidants and their influence on population health, the monograph presents results from a research project included in the program "Research Support for Enhancing the Defense Capabilities of the Czech Republic in NATO Structures."

The research was conducted between 2010 and 2012 as part of preventive rehabilitation programs for professional soldiers with a sports component. The study involved 218 professional soldiers, including 180 men and 38 women, with an average age of 33.3 years. The current health status and dietary habits of the soldiers were assessed using questionnaires.

The study described the saturation of the observed group with antioxidant vitamins and statistically evaluated the relationship between their levels and the risk indicators for the development of cardiovascular diseases. Individual analyses were performed using the Reflotron device calibrated with Reflotron Precinorm control serum. Following blood collection, all participants underwent anthropometric examinations (body weight, height, waist circumference), blood pressure measurements, heart rate monitoring, and physical fitness assessments through simple functional tests.

This scientific monograph is suitable for the scientific community, students of medical, veterinary, and natural sciences, as well as public health students at all levels of university education. It is also intended for informed members of the public.

Organic chemistry plays a key role in our lives, from the pharmaceutical industry to the production of plastics and food additives. Additionally, it is essential in biochemistry, as it deals with the basic building blocks of living organisms, such as carbohydrates, lipids, proteins, and nucleic acids. One of the best ways to teach organic chemistry and increase students' interest in the subject is through conducting school experiments. This study material presents a collection of visually striking practical experiments in organic chemistry that will help students better understand the chemical processes and techniques used in the field. This electronic study material is supplemented with visual material, allowing students to verify the results of experiments and better understand the individual procedures. At the end of each section, there are questions to help assess the acquired knowledge and encourage deeper understanding of the experiments conducted.

The university textbook entitled: Host-guest and supramolecular chemistry provides basic information about this scientific field as well as the types of compounds that belong to it. It provides basic characteristics of non-bonded interactions as well as methods of characterization and classification for these compounds. It summarizes knowledge about various types of host-guest systems from the oldest such as Hofmann clathrates to inclusive compounds such as cyclodextrins and calixarenes. In addition to structural and synthetic information, which is supplemented with images, the textbook also addresses the possibilities of application or practical use of compounds. The conclusion of each chapter is supplemented with tasks for elaboration on a given topic.
