Age and signal strength-related changes in vessel density in the choroid and the retina: an OCT angiography study of the macula and optic disc
(2022)Purpose: To investigate the effects of ageing and signal strength index (SSI) on vessel density (VD) measurements of the radial peripapillary capillaries (RPC) in the optic disc, the retinal superficial (SCP) and deep (DCP) ... -
Age differences in cardiac autonomic regulation during intermittent exercise in the heat
(2020)Purpose: This study aimed to detect potential differences in heart-rate variability (HRV) during a moderate-intensity intermittent exercise in the heat among physically active young (25.8 ± 1.9 years), middle-aged (43.5 ± ... -
Age structure changes and extraordinary lifespan in wild medfly populations
(2008)The main purpose of this study was to test the hypotheses that major changes in age structure occur in wild populations of the Mediterranean fruit fly (medfly) and that a substantial fraction of individuals survive to ... -
Age, human performance, and physical employment standards
(2016)The proportion of older workers has increased substantially in recent years, with over 25% of the Canadian labour force aged ≥55 years. Along with chronological age comes age-related declines in functional capacity associated ... -
Age, sex, adult and larval diet shape starvation resistance in the Mediterranean fruit fly: an ecological and gerontological perspective
(2019)The ability of an animal to withstand periods of food deprivation is a key driver of invasion success (biodiversity), adaptation to new conditions, and a crucial determinant of senescence in populations. Starvation resistance ... -
Aging Impairs Whole-Body Heat Loss in Women under Both Dry and Humid Heat Stress
(2017)Purpose This study was designed to determine whether age-related impairments in whole-body heat loss, which are known to exist in dry heat, also occur in humid heat in women. Methods To evaluate this possibility, 10 young ... -
Altered activity of xenobiotic detoxifying enzymes at menopause – A cross-sectional study
(2020)Xenobiotic metabolism at menopause is an under-investigated topic, albeit women spend one-third of their life in the postmenopausal period. The present study examined the effect of menopause on the in vivo activities of ... -
Apolipoprotein ϵ4 allele is associated with frailty syndrome: Results from the hellenic longitudinal investigation of ageing and diet study
(2019)Apolipoprotein (APOE) ϵ4 allele has been associated with a number of age-related diseases but previous studies failed to identify any link with Frailty syndrome. The aim of the present study is to investigate the association ... -
Assessing multiple-group diagnostic problems with multi-dimensional receiver operating characteristic surfaces: Application to proton MR Spectroscopy (MRS) in HIV-related neurological injury
(2008)We present the multi-dimensional Receiver Operating Characteristic (ROC) surface, a plot of the true classification rates of tests based on levels of biological markers, for multi-group discrimination, as an extension of ... -
Association between 9p21–23 Locus and Frailty in a Community-Dwelling Greek Population: Results from the Hellenic Longitudinal Investigation of Ageing and Diet
(2022)Background: Frailty is a complex geriatric syndrome arising from a combination of genetic and environmental factors and is associated with adverse health outcomes and mortality. A recent study reported an association between ... -
Association of KLOTHO Gene Polymorphisms with Knee Osteoarthritis in Greek Population
(2008)Based on the fact that klotho-deficient mice exhibit multiple aging phenotypes, including osteopenia and subchondral sclerosis of joints and on the recent observation that KLOTHO gene plays an important role in calcium/phosphate ... -
Associations between the mediterranean diet and sleep in older adults: Results from the hellenic longitudinal investigation of aging and diet study
(2018)Aim: Although there is some evidence of the relationships between sleep duration/quality and nutrient and/or food intake, the associations between sleep and dietary patterns have been poorly explored. The aim of the present ... -
Attractor Divergence as a Metric for Assessing Walking Balance
(2010)Individuals with Parkinson's disease and the aged have a high prevalence of falls. Since an increase in the number of falls is associated with physical and psychological harm, it is prudent that biomechanical metrics be ... -
Can maximal handgrip strength and endurance be improved by an 8-week specialized strength training program in older women? A randomized controlled study [La force maximale et l'endurance de la poigne peuvent-elles être améliorées après un programme de musculation spécialisé de 8 semaines chez les femmes âgées? Une étude contrôlée randomisée]
(2021)Maximal handgrip strength and endurance are important indicators of upper limb function in older adults. Up to now, there is insufficient information regarding the efficacy of specialized strength training programs for ... -
Causes of blindness and vision impairment in 2020 and trends over 30 years, and prevalence of avoidable blindness in relation to VISION 2020: The Right to Sight: An analysis for the Global Burden of Disease Study
(2021)Background: Many causes of vision impairment can be prevented or treated. With an ageing global population, the demands for eye health services are increasing. We estimated the prevalence and relative contribution of ... -
Chronic obstructive pulmonary disease as a main factor of premature aging
(2019)(1) Background: Chronic obstructive pulmonary disease (COPD) is defined as an inflammatory disorder that presents an increasingly prevalent health problem. Accelerated aging has been examined as a pathologic mechanism of ... -
