Biochemical Foundations of Pathological Processes: A Textbook for Medical Students, edited by E. C. Severin and with the participation of Lyudmila Avdeeva and other authors, is an important and relevant work in the field of medical science. This manual will become an indispensable companion for students, graduate students and practitioners seeking a deeper understanding of the biochemical mechanisms underlying various pathologies. This tutorial examines key aspects of biochemistry that are directly related to pathological processes in the human body. The authors seek to explain how disorders in biochemical reactions can lead to the development of diseases, and how this knowledge can be used for diagnosis and treatment. The reader is immersed in a world of molecules and cells, where every reaction matters, and every mistake can lead to serious consequences for health. The book covers a wide range of topics, including metabolism, cellular signaling, drug mechanisms of action, and more. It not only provides theoretical knowledge, but also includes practical examples, which makes the material more accessible and understandable. Students studying medicine will find useful diagrams, tables and illustrations in it that will help to visualize complex processes and remember key points. This manual will be especially interesting for those who want to deepen their knowledge in the field of biochemistry and its application in medicine. It is suitable not only for students of medical universities, but also for doctors who want to refresh their knowledge or learn new approaches to the diagnosis and treatment of diseases. The book will also be useful to teachers who are looking for quality materials for their courses. The topics raised in the book cover important aspects, such as the influence of genetic factors on biochemical processes, the role of nutrition in the development of diseases, as well as modern approaches to therapy. These questions remain relevant in light of current health challenges, and understanding the biochemical underpinnings of pathologies is becoming increasingly important for successful physician practice. Lyudmila Avdeeva, known for her scientific works and teaching activities, has a unique style of presentation that combines accessibility and deep scientific validity. Her other works are also devoted to biochemistry and medicine, and they have earned recognition among both students and professionals. The book “Biochemical Foundations of Pathological Processes” continues this tradition, offering readers high-quality and relevant material. If you are looking for a tutorial that will help you understand the complex biochemical processes and their relationship with pathology, this publication will be a real find for you. It will not only deepen your knowledge, but also inspire you to further study biochemistry and medicine. Do not miss the opportunity to discover a world where every molecule matters, and every biochemical reaction can be the key to understanding health and disease.
