Heart disease or cardiovascular disease are the class of diseases that involve the heart or blood vessels (arteries and veins). While the term technically refers to any disease that affects the cardiovascular system (as used in MeSH C14), it is usually used to refer to those related to atherosclerosis (arterial disease). These conditions usually have similar causes, mechanisms, and treatments.Most countries face high and increasing rates of cardiovascular disease. Each year, heart disease kills more Americans than cancer. In recent years, cardiovascular risk in women has been increasing and has killed more women than breast cancer. A large histological study (PDAY) showed vascular injury accumulates from adolescence, making primary prevention efforts necessary from childhood. By the time that heart problems are detected, the underlying cause (atherosclerosis) is usually quite advanced, having progressed for decades. There is therefore increased emphasis on preventing atherosclerosis by modifying risk factors, such as healthy eating, exercise and avoidance of smoking.

Bioinformatics is the application of statistics andcomputer science to the field of molecularbiology.The term bioinformatics was coined by PaulienHogeweg and Ben Hesper in 1978 for the study ofinformatic processes in biotic systems. Its primaryuse since at least the late 1980s has been ingenomics and genetics, particularly in those areas ofgenomics involving large-scale DNAsequencing.Bioinformatics now entails the creationand advancement of databases, algorithms,computational and statistical techniques and theoryto solve formal and practical problems arising fromthe management and analysis of biological data. Overthe past few decades rapid developments in genomicand other molecular research technologies anddevelopments in information technologies havecombined to produce a tremendous amount ofinformation related to molecular biology. It is thename given to these mathematical and computingapproaches used to glean understanding of biologicalprocesses.Common activities in bioinformatics includemapping and analyzing DNA and protein sequences,aligning different DNA and protein sequences tocompare them and creating and viewing 3-D models ofprotein structures.

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 and understand, rather than including a lot of reference material. This has enabled us to keep its length down. Another feature has been to include many new illustrations to aid in grasping the diagnosis and management. Many patients use herbal or other alternative medicines and there is a new addition on this important topic.

Phytotherapy is the study of the use of extracts from natural origin as medicines or health-promoting agents. Traditional phytotherapy is often used as synonym for herbalism and regarded as "alternative medicine" by much of Western medicine. Modern phytotherapy when critically conducted, can be considered the scientific study on the effects and clinical use of herbal medicines.Medicinal plants have always been considered a healthy source of life for all people.Therapeutical properties of medical plants are very useful in healing various diseases and the advantage of these medicinal plants is being 100% natural. Nowadays people are being bombarded with thousand of unhealthy products, the level of sensibility in front of diseases is very high and that''s why the use of medicinal plants can represent the best solution.
