Therapeutics, Treatment and care to combat disease or alleviate pain or injury. Its tools include drugs, surgery, radiation therapy, mechanical devices, diet, and psychiatry. Treatment may be active, to cure a disease (requiring no further treatment after recovery), treat it long-term, or heal a wound; symptomatic, to relieve symptoms until the immune system heals the body; supportive, to keep body functions going until the disease clears; or palliative, to minimize discomfort for patients with no chance of recovery.

For even the most successful series of textbook editions, there comes a time for an ending and a new beginning. This book is just such a new beginning. This text aims to communicate the clinical art and wisdom of psychiatry, tied firmly to the science of clinical disciplines. This text aims to be both scholarly and practical. It covers the most important topics in the format that is complete and efficient for the mental health professional in training or the clinician seeking an update. It differs from the other books in that it concentrates exclusively on aspects that students should know...

Biochemistry is the study of the structure, composition, and chemical reactions of substances in living systems. Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, or physical chemistry and began to study such topics as how living things obtain energy from food, the chemical basis of heredity, and what fundamental changes occur in disease. Biochemistry includes the sciences of molecular biology; immunochemistry; neurochemistry; and bioinorganic, bioorganic, and biophysical chemistry.

Biochemistry, sometimes called biological chemistry, is the study of chemical processes in living organisms, including, but not limited to, living matter. Biochemistry governs all living organisms and living processes. By controlling information flow through biochemical signalling and the flow of chemical energy through metabolism, biochemical processes give rise to the incredible complexity of life. Much of biochemistry deals with the structures and functions of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules although increasingly processes...
