Understanding how we age: insights into inflammagingSpringer Science and Business Media LLC - Tập 2 - Trang 1-8 - 2013
Daniel Baylis, David B Bartlett, Harnish P Patel, Helen C Roberts
Inflammaging is characterized by the upregulation of the inflammatory response that occurs with advancing age; its roots are strongly embedded in evolutionary theory. Inflammaging is believed to be a consequence of a remodelling of the innate and acquired immune system, resulting in chronic inflammatory cytokine production. Complex interrelated genetic, environmental and age-related factors determ...... hiện toàn bộ
A midlife crisis for the mitochondrial free radical theory of agingSpringer Science and Business Media LLC - Tập 3 - Trang 1-15 - 2014

Since its inception more than four decades ago, the Mitochondrial Free Radical Theory of Aging (MFRTA) has served as a touchstone for research into the biology of aging. The MFRTA suggests that oxidative damage to cellular macromolecules caused by reactive oxygen species (ROS) originating from mitochondria accumulates in cells over an animal’s lifespan and eventually leads to the dysfunction and f...... hiện toàn bộ

Abstract
Background
The aim of the present study was to determine the influence of age and habitual activity level, at rest and following a single bout of high-intensity exercise, on the levels of three proteins poly(ADP-ribose) polymerase-1 (PARP-1), cleaved-PARP-1 and poly(ADP-ribose) glycohydr...... hiện toàn bộ

Alteration in the immune system is one of the most profound aspects of aging. Progressive changes in the number of B lymphocyte progenitors during aging have been reported but the underlying mechanisms are still elusive. A heterozygous G608G mutation in the LMNA gene leads to a deletion of 50 amino acids in lamin A protein, termed progerin, and is the predominant cause of Hutchinson-Gilford proger...... hiện toàn bộ
The role of mitochondria in longevity and healthspanSpringer Science and Business Media LLC - Tập 3 - Trang 1-3 - 2014
Martin D Brand
The role of mitochondria in aging and disease remains contentious more than 40 years after the mitochondrial free radical theory of aging was first proposed. As part of a wider cross-journal series on contemporary mitochondrial biology, Longevity & Healthspan presents a thematic series of four reviews that discuss the evidence for and against the modern incarnations of the theory, and examine the ...... hiện toàn bộ
Life-long spontaneous exercise does not prolong lifespan but improves health span in miceSpringer Science and Business Media LLC - Tập 2 - Trang 1-12 - 2013

Life expectancy at birth in the first world has increased from 35 years at the beginning of the 20th century to more than 80 years now. The increase in life expectancy has resulted in an increase in age-related diseases and larger numbers of frail and dependent people. The aim of our study was to determine whether life-long spontaneous aerobic exercise affects lifespan and healthspan in mice. Male...... hiện toàn bộ
