Geriatrics, or geriatric medicine, is a medical specialty focused on providing care for the unique health needs of the elderly. The term geriatrics originates from the Greek γέρων geron meaning "old man", and ιατρός iatros meaning "healer". It aims to promote health by preventing, diagnosing and treating disease in older adults. There is no defined age at which patients may be under the care of a geriatrician, or geriatric physician, a physician who specializes in the care of older people. Rather, this decision is guided by individual patient need and the caregiving structures available to them. This care may benefit those who are managing multiple chronic conditions or experiencing significant age-related complications that threaten quality of daily life. Geriatric care may be indicated if caregiving responsibilities become increasingly stressful or medically complex for family and caregivers to manage independently.
Elizabeth Helen Blackburn, is an Australian-American Nobel laureate who is the former president of the Salk Institute for Biological Studies. In 1984, Blackburn co-discovered telomerase, the enzyme that replenishes the telomere, with Carol W. Greider. For this work, she was awarded the 2009 Nobel Prize in Physiology or Medicine, sharing it with Carol W. Greider and Jack W. Szostak, becoming the first Australian woman Nobel laureate.
Biomedicine is a branch of medical science that applies biological and physiological principles to clinical practice. Biomedicine stresses standardized, evidence-based treatment validated through biological research, with treatment administered via formally trained doctors, nurses, and other such licensed practitioners.
Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage. Disturbances in the normal redox state of cells can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell, including proteins, lipids, and DNA. Oxidative stress from oxidative metabolism causes base damage, as well as strand breaks in DNA. Base damage is mostly indirect and caused by the reactive oxygen species generated, e.g., O2− (superoxide radical), OH (hydroxyl radical) and H2O2 (hydrogen peroxide). Further, some reactive oxidative species act as cellular messengers in redox signaling. Thus, oxidative stress can cause disruptions in normal mechanisms of cellular signaling.
The USC Leonard Davis School of Gerontology is one of the seventeen academic divisions of the University of Southern California in Los Angeles, focusing on undergraduate and graduate programs in gerontology.
Carol Davila University of Medicine and Pharmacy or University of Medicine and Pharmacy Bucharest, commonly known by the abbreviation UMFCD, is a public health sciences university in Bucharest, Romania. It is one of the largest and oldest institutions of its kind in Romania. The university uses the facilities of over 20 clinical hospitals all over Bucharest.
The College of Biological Sciences (CBS) is one of seven freshman-admitting colleges at the University of Minnesota. Established in 1869 as the College of Science, the College of Biological Science is now located across both the Minneapolis and the St. Paul campuses. As of June 29, 2023, the dean of the College of Biological Sciences is Dr. Saara J DeWalt.
The Pennington Biomedical Research Center is a health science-focused research center in Baton Rouge, Louisiana. It is part of the Louisiana State University System and conducts clinical, basic, and population science research. It is the largest academically-based nutrition research center in the world, with the greatest number of obesity researchers on faculty. The center's over 500 employees occupy several buildings on the 222-acre (0.90 km2) campus. The center was designed by the Baton Rouge architect John Desmond.
Frailty is a common geriatric syndrome that embodies an elevated risk of catastrophic declines in health and function among older adults. Frailty is a condition associated with ageing, and it has been recognized for centuries. It is a marker of a more widespread syndrome of frailty, with associated weakness, slowing, decreased energy, lower activity, and, when severe, unintended weight loss. As a frequent clinical syndrome in the elderly, various health risks are linked to health deterioration and frailty in older age, such as falls, disability, hospitalization, and mortality. Generally, frailty refers to older adults who lose independence. It also links to the experiences of losing dignity due to social and emotional isolation risk. Frailty has been identified as a risk factor for the development of dementia.
The Journals of Gerontology are the first scientific journals on aging published in the United States. The publication is separated into four separate peer-reviewed scientific journals, each with its own editor, and published in two series. The Journal of Gerontology: Biological Sciences and the Journal of Gerontology: Medical Sciences are housed within The Journals of Gerontology, Series A; the Journal of Gerontology: Psychological Sciences and the Journal of Gerontology: Social Sciences are housed within The Journals of Gerontology, Series B. The journals are published by Oxford University Press on behalf of The Gerontological Society of America.
The School of Biological Sciences is a School within the Faculty Biology, Medicine and Health at The University of Manchester. Biology at University of Manchester and its precursor institutions has gone through a number of reorganizations, the latest of which was the change from a Faculty of Life Sciences to the current School.
Allied Academies is a reportedly fraudulent corporation chartered under the laws of North Carolina. Its postal address is in London, United Kingdom. It presents itself as an association of scholars, with supporting and encouraging research and the sharing and exchange of knowledge as its stated aims. The organization consists of 30 affiliate academies, which provide awards to academics and publish academic journals both online and in hard copy for members. Since 2015 the organization has been listed on Jeffrey Beall's list of "potential, possible, or probable predatory scholarly open-access publishers". It is in a partnership with OMICS Publishing Group which uses its website and logo. In 2018, OMICS owner Srinubabu Gedela declared that he had informed the Nevada court that Allied Academies was a subsidiary of OMICS International. During a conference in 2018, they falsely listed a prominent chemist among its organizing committee who had not agreed to this and was not affiliated with Allied Academies.
Henry Jay Forman is both Distinguished Professor Emeritus of Biochemistry at the University of California, Merced. and Research Professor Emeritus of Gerontology at the University of Southern California (USC) Leonard Davis School of Gerontology. He is a specialist in free radical biology and chemistry, antioxidant defense, and pioneered work in redox signaling including the mechanisms of induced resistance to oxidative stress.
The mitochondrial theory of ageing has two varieties: free radical and non-free radical. The first is one of the variants of the free radical theory of ageing. It was formulated by J. Miquel and colleagues in 1980 and was developed in the works of Linnane and coworkers (1989). The second was proposed by A. N. Lobachev in 1978.
Herald Scholarly Open Access is a publisher of various academic journals. It has a postal address in Herndon, Virginia, United States, but is actually based in Hyderabad, India. Herald Scholarly Open Access has been included on Beall's List of potential predatory open-access publishers, and has faced other criticisms of its publishing practices.
