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

A midlife crisis for the mitochondrial free radical theory of agingSpringer Science and Business Media LLC - Tập 3 - Trang 1-15 - 2014
Jeffrey A Stuart, Lucas A Maddalena, Max Merilovich, Ellen L Robb
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) glycohydrolase
(PARG), involved in the DNA repair and cell death responses to stress and
genotoxic insults. Musc... 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
