This book presents a series of protocols in multiple disease areas affected by the aging process along with several methods which have shown progress in nutrient- or intervention-based approaches to maximize the healthspan. Of interest to researchers in the areas of chronic disease, gerontology, physical exercise, and nutrition as well as to clinical scientists, physicians, and pharmacologists, this volume also provides important information on disease mechanisms and novel drug targets as each protocol will be presented in the context of specific chronic diseases or different therapeutic areas. Written for the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
