Reduction in Fracture Resistance of the Root with Aging
Journal of Endodontics, 2017The incidence of vertical root fracture in endodontically treated teeth increases with patient age. This study evaluated the microstructure, chemical composition, and mechanical properties of radicular dentin as a function of aging.Single-rooted teeth were obtained from adult donors ranging from age 15 to older than 80 years.

Abstract The present paper explores the language of aging used, often unthinkingly, by nurses and policy makers. Terms so often used when describing aging, such as ‘frailty’ and ‘dependence’, are used in a way that implies a common knowledge, a point of convergence.

Insulin resistance and accelerated cognitive aging
Psychoneuroendocrinology, 2023Insulin resistance may be an early sign of metabolic dysfunction with the potential to lead to neuropsychiatric sequelae in the long term. In order to identify whether insulin resistance in otherwise healthy young and middle-aged adults is associated with preclinical signs of neuropsychiatric impairment, we recruited 126 overweight but nondiabetic ...

Insulin resistance and pathological brain ageing
Diabetic Medicine, 2011Diabet. Med. 28, 1463–1475 (2011)AbstractSir Harold Himsworth’s prescient observations 75 years ago have recently been expanded to include a clear relationship between insulin resistance and central nervous system function. Insulin is a master regulator of corporeal ageing in all known species, determining the rate and expression of ageing in multiple ...

Insulin resistance, a reduction in the rate of glucose disposal elicited by a given insulin concentration, is present in individuals who are obese, and those with diabetes mellitus, and may develop with aging. Methods which are utilised to measure insulin sensitivity include the hyperinsulinaemic-euglycaemic and hyperglycaemic clamps and the ...

Resistance of aged cells to virus replication
Experimental Gerontology, 1979Abstract The phenomenon of resistance of aged cells to virus replication was investigated in aged L929 cell monolayers infected with Semliki Forest virus. By inhibiting the production and action of interferon, we showed that only about one-third of the 4·5 log restriction in virus replication could be attributed to the antiviral activity of the ...

Insulin-resistance (IR) in older age
Archives of Gerontology and Geriatrics, 2008A study pool of 1549 normoglycemic elderly in the age range of 65-84 years, taken from the epidemiological Italian Longitudinal Study on Aging (ILSA), was constructed. The values of IR, %B and %S were analyzed using the homeostasis assessment model-2 (HOMA-2).

Age-Related Insulin Resistance; A Review
Hormone Research, 2008Impaired glucose tolerance occurs with age. This impairment is multifactorial including a decrease in insulin-mediated glucose uptake by peripheral tissues and a delay in insulin-induced suppression of hepatic glucose output. A post-binding defect in insulin action such as a reduced capacity to transcribe more glucose transporter mRNA and/or a reduced ...

Headlight Glare Resistance and Driver Age
Proceedings of the Human Factors Society Annual Meeting, 1978The physiological glare thresholds (defined as the logarithm of the ratio at threshold between illuminances of glare source and target background) of 148 subjects from 5 to 91 years of age were measured in a Wolf glare tester. The data can be represented by a power function: (physiological glare threshold) =—3 × 10

Terrorism and the Internet: Resistance in the Information Age
Knowledge, Technology & Policy, 2003The purpose of this paper is to document the relationship between technology and terrorism. The discussion will focus on the Internet, in an attempt to discover whether the threat of insurgency is justification for the increasingly restrictive privacy of Internet users.
