MARK-AGE biomarkers of ageing [PDF]

open access: yesMechanisms of Ageing and Development, 2015
Many candidate biomarkers of human ageing have been proposed in the scientific literature but in all cases their variability in cross-sectional studies is considerable, and therefore no single measurement has proven to serve a useful marker to determine, on its own, biological age.

To age or not to age

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2004
According to the antagonistic pleiotropy theory of ageing, natural selection has favoured genes conferring short-term benefits to the organism at the cost of deterioration in later life. The 'disposable soma' theory expresses this as a life-history strategy in which somatic maintenance is below the level required to prevent ageing, thus enabling higher

The future of Age and Ageing [PDF]

open access: yesAge and Ageing, 2002
The delivery of healthcare in the United Kingdom is going through a period of change, with many new developments. Some of these represent the aspirations of politicians and those who manage the National Health Service, and others are being forced upon us because of the shortage of resources (not always financial).

Ageing and vascular ageing [PDF]

open access: yesPostgraduate Medical Journal, 2006
Abstract There is an age related decline in various physiological processes. Vascular ageing is associated with changes in the mechanical and the structural properties of the vascular wall, which leads to the loss of arterial elasticity and reduced arterial compliance.

Age and Ageing: An Overview [PDF]

open access: yesOccupational Medicine, 2000
Europe is ageing, as exemplified by the UK population where, in the foreseeable future, more people will be over than under age 50: industry appears slow to recognise and appreciate all that older workers still have to offer: bundling them off into early retirement wastes precious talents. Memory difficulty is not an inevitable part of ageing.

Aging [PDF]

open access: yesKorean Journal of Audiology, 2013
Aging is initiated based on genetic and environmental factors that operate from the time of birth of organisms. Aging induces physiological phenomena such as reduction of cell counts, deterioration of tissue proteins, tissue atrophy, a decrease of the metabolic rate, reduction of body fluids, and calcium metabolism abnormalities, with final progression

A role for worm cutl-24 in background- and parent-of-origin-dependent ER stress resistance

open access: yesBMC Genomics, 2022
Background Organisms in the wild can acquire disease- and stress-resistance traits that outstrip the programs endogenous to humans. Finding the molecular basis of such natural resistance characters is a key goal of evolutionary genetics.

The pace and prognosis of peripheral sensory loss in advanced age: association with gait speed and falls

open access: yesBMC Geriatrics, 2018
Background Peripheral sensory loss is considered one of many risk factors for gait impairments and falls in older adults, yet no prospective studies have examined changes in touch sensation in the foot over time and their relationship to mobility and ...

Establishment and evaluation of module-based immune-associated gene signature to predict overall survival in patients of colon adenocarcinoma

open access: yesJournal of Biomedical Science, 2022
Background Patients with colon adenocarcinoma (COAD) exhibit significant heterogeneity in overall survival. The current tumor-node-metastasis staging system is insufficient to provide a precise prediction for prognosis.
