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.

This scientific monograph is a comprehensive scientific work focused on the presence and effects of mercury in the environment, as well as the health risk factors associated with it.

The monograph presents a characterization of mercury in a multidisciplinary scope, discusses its use in industry and healthcare, and describes the negative impacts of mercury on the environment and public health. It also provides proposals and recommendations for at-risk groups. The monograph includes a comprehensive study of mercury concentration in samples of domestic and foreign production commodities and plant samples using the atomic absorption spectrometer AMA 254.

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

A well-known proverb says: "It is better to see once than to hear a hundred times." With this in mind, the electronic version of the teaching materials has been designed, as we are convinced that practical laboratory experience is irreplaceable and still holds its significance in university studies.

In the provided teaching texts, you will find a set of experiments that complement and help better understand the theoretical knowledge gained through self-study as well as lectures in an appropriate manner. Additionally, this e-version allows students, after printing and subsequently completing individual tables, observations, and conclusions, to submit them as a laboratory report that confirms they have successfully mastered the assigned tasks.

This university textbook is intended for students of the Faculty of Science of the University of Applied Sciences in Košice who have enrolled in practical exercises in Biotechnology, but also for all other students who are interested in learning about the practical applications of biotechnology.

The aim of the practical course is to familiarize students with basic biotechnological methods and their applications. The students will verify in practice the theoretical knowledge acquired in the Biotechnology lectures such as the course of fermentation processes, wine production, preparation of fermented milk products and cheese, preparation of culture media, inoculation and cultivation of microorganisms, etc. The practical exercises also include the use of analytical and spectral methods, which are an integral part of biochemistry.

The scripts are published only in electronic form and are available on the University's website: http://kosice.upjs.sk/~kbch/sk, for the reason that it will always be possible to update and modernize the content of the laboratory exercises.

This university text is intended for students of chemical and ecological sciences at the Faculty of Natural Sciences of the P. J. Šafárik University in Košice and is intended to serve as a tool for experimental exercises in colloid chemistry. Colloid chemistry is an important part of the theoretical basis of the chemical sciences and belongs to the newer interdisciplinary fields of natural sciences.

It combines knowledge from physical chemistry, physics and biology, while also drawing on a solid knowledge of mathematics and other scientific disciplines. Experiments are often essential in understanding the problems of colloid chemistry, modelling ideas about the phenomena and laws involved in the discipline. This is why active participation in experimental exercises is so important and essential to mastering the material in colloid chemistry.

In selecting the tasks for these scripts, it was also necessary to respect the considerable limitations imposed by the possibilities of the laboratory instrumentation and material equipment of our department. Despite this limitation, however, they can illustrate to students the basic theoretical physicochemical principles of colloid dispersion systems and, importantly, their understanding can contribute to the understanding of some of the more important peculiarities of colloidal phenomena.

Electrochemistry is the science that studies ionic systems and the processes or phenomena that occur at the interface between ionic systems and metals or semiconductors. At the current stage of development, electrochemistry can be divided into two main areas based on its focus. The first one - ionics - deals with the properties of ionic systems (solutions, melts, solid electrolytes). The second area - electrodeics - focuses on phenomena at the electrode/ionic system interface.

Both ionics and electrodeics investigate equilibrium and non-equilibrium phenomena and processes. Research into the properties of ionic systems under equilibrium conditions provides information and insights into the structure and composition of electrolyte solutions, melts, and solid electrolytes, while measurements under non-equilibrium conditions provide data on the electrical conductivity of ionic systems. In the field of electrodeics, the study of equilibria at the electrode/solution (or melt) interface is the domain of electrochemical thermodynamics. Measuring the rates of processes occurring at this phase interface and explaining the principles governing these processes fall under the scope of electrode process kinetics or electrochemical kinetics.
