This detailed book explores protocols with the aim of testing aerobic exercise, resistance training, special diets, additives and natural products, which have led to new insights into the physiological and molecular aspects of health and disease. Many of these approaches have contributed to significant improvements in disease areas such as cardiovascular disease, cognitive dysfunction, diabetes, frailty, gliobastoma, metabolic syndrome, obesity, oxidative stress, and various cancers. This collection also provides important information on disease mechanisms and novel drug targets as each protocol is presented in the context of specific chronic diseases or different therapeutic areas. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials, step-by-step, readily reproducible protocols, and tips on troubleshooting and avoiding known pitfalls.
