Beta2-adrenergic receptor gene polymorphisms as systemic determinants of healthy aging in an evolutionary context.
(Mech Ageing Dev, 2010-05)
The Gln(27)Glu polymorphism but not the Arg(16)Gly polymorphism of the beta2-adrenergic receptor (ADRB2) gene appears to be associated with a broad range of aging-associated phenotypes, including cancers at different sites, ...
Differential developmental trajectories of magnetic susceptibility in human brain gray and white matter over the lifespan.
(Hum Brain Mapp, 2014-06)
As indicated by several recent studies, magnetic susceptibility of the brain is influenced mainly by myelin in the white matter and by iron deposits in the deep nuclei. Myelination and iron deposition in the brain evolve ...
Age-related effects on the neural correlates of autobiographical memory retrieval.
(Neurobiol Aging, 2012-07)
Older adults recall less episodically rich autobiographical memories (AM), however, the neural basis of this effect is not clear. Using functional MRI, we examined the effects of age during search and elaboration phases ...
Polymorphisms in the ACE and ADRB2 genes and risks of aging-associated phenotypes: the case of myocardial infarction.
(Rejuvenation Res, 2010-02)
Multiple functions of the beta2-adrenergic receptor (ADRB2) and angiotensin-converting enzyme (ACE) genes warrant studies of their associations with aging-related phenotypes. We focus on multimarker analyses and analyses ...
Adult age differences in functional connectivity during executive control.
Task switching requires executive control processes that undergo age-related decline. Previous neuroimaging studies have identified age-related differences in brain activation associated with global switching effects (dual-task ...
Long-term dynamics of death rates of emphysema, asthma, and pneumonia and improving air quality.
(Int J Chron Obstruct Pulmon Dis, 2014)
BACKGROUND: The respiratory tract is a major target of exposure to air pollutants, and respiratory diseases are associated with both short- and long-term exposures. We hypothesized that improved air quality in North Carolina ...
