Galen in the 2nd century AD could be considered one of the earliest researchers who attempted to bridge the gap between basic science and clinical medicine. Galen is given initial credit for the recognition that vital organs of the body are exquisitely dependent upon the intact function of the circulatory system. The doctrines of Galenic physiology stated that blood was produced in the liver, flowed to the heart to obtain "vital spirits," and subsequently bathed the brain to gain "animal spirits." The "vital spirits" described by Galen were later disclosed to consist of oxygen. Oxygen was...

Features that characterize the aging process include the gradual accumulation of cell damage after prolonged exposure to oxidative and inflammatory events over a lifetime. In addition to the accretion of lesions, the intrinsic levels of pro-oxidant and aberrant immune responses are elevated with age. These adverse events are often further enhanced by the chronic and slow progressing diseases that characterize the senescent brain and cardiovascular system. The incidence of some disorders such as Alzheimer's disease and vascular diseases are sufficiently prevalent in the extreme elderly that...

Molecules to Medicine with mTOR: Translating Critical Pathways into Novel Therapeutic Strategies is a one-stop reference that thoroughly covers the mechanistic target of rapamycin (mTOR). mTOR, also known as the mammalian target of rapamycin, is a 289-kDa serine/threonine protein kinase that is ubiquitous throughout the body and has a critical role in gene transcription and protein formation, stem cell development, cell survival and senescence, aging, immunity, tissue regeneration and repair, metabolism, tumorigenesis, oxidative stress, and pathways of programmed cell death that...
