Biomedical Advances in Aging

The VIIIth Annual International Spring Symposium on Health Sciences held at the George Washington University School of Medicine in Washington, D.C., attracted over three hun dred fifty scientists from twenty-five countries. The leading scientific experts in the field reported on recent biomedical advances in aging. They provided an up-to-date account of the molecular, genetic, nutritional, and immunological mechanisms associated with the aging process and approaches to intervention and treatment of the major disorders associated with the aging process, including Alzheimer's disease. A unique aspect of this meeting was a concurrent one-day hearing of the U.S. Senate Sub-Committee on Aging, organized by the Alliance for Aging Research. The theme for the hearing was "Advances in Aging Research." Seven scientists attending our aging sym posium were asked to testify. They were Drs. Carl Cotman (University of California-Irvine), Trudy Bush (Johns Hopkins University), Takashi Makinodan (University of California-Los Angeles), William Ershler (University of Wisconsin-Madison), Gino Doria (ENEA, Rome), Mr. Dan Perry (Director of the Alliance for Aging Research), and myself.

Résumé

From Book News, Inc.
The VIIIth Annual Symposium provides new information on molecular and immunological mechanisms, intervention and clinical approaches to treatment of diseases associated with aging, and with the aging process itself. The 56 papers are arranged into six major sections covering: molecular biology, virology, and genetics of Alzheimer's disease; metabolic, membrane, and cellular markers and models; role of nutritional, dietary, and immune factors in the pathogenesis of aging; immunological components and immunoregulation in aging; the brain, neuroendocrine circuits, pathology, and plasticity; and immunological, endocrine, and pharmacological approaches to treatment of diseases of aging.
