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 related changes in ocular motor testing in healthy subjects
(2015)The aim of the present study was the investigation of age influenced changes in ocular motility testing in healthy subjects. Two hundred and fifty subjects between 18 and 70 years old were enrolled in a prospective study. ... -
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 ... -
Age-dependent changes in 8-oxoguanine-DNA glycosylase activity are modulated by adaptive responses to physical exercise in human skeletal muscle
(2011)8-Oxo-7,8-dihydroguanine (8-oxoG) accumulates in the genome over time and is believed to contribute to the development of aging characteristics of skeletal muscle and various aging-related diseases. Here, we show a ... -
Age-specific and lifetime behavior patterns in Drosophila melanogaster and the Mediterranean fruit fly, Ceratitis capitata
(2006)Patterns of behavior were recorded every 10 min during a 2-h period each day from eclosion to death for individual Drosophila melanogaster (both sexes) and Ceratitis capitata (males-only) including walking, preening, ... -
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 ... -
Aging is not a barrier to muscle and redox adaptations: Applying the repeated eccentric exercise model
(2013)Despite the progress of analytic techniques and the refinement of study designs, striking disagreement exists among studies regarding the influence of exercise on muscle function and redox homeostasis in the elderly. The ... -
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 ... -
Behavioral trajectories as predictors in event history analysis: Male calling behavior forecasts medfly longevity
(2006)A recent study on wild male Mediterranean fruit flies [Papadopoulos, N.T., Katsoyannos, B.I., Kouloussis, N.A., Carey, J.R., Müller, H.-G., Zhang, Y., 2004. High sexual signalling rates of young individuals predict extended ... -
Can a Virtual Reality Cognitive Training Application Fulfill a Dual Role? Using the Virtual Supermarket Cognitive Training Application as a Screening Tool for Mild Cognitive Impairment
(2015)Background: Recent research advocates the potential of virtual reality (VR) applications in assessing cognitive functions highlighting the possibility of using a VR application for mild cognitive impairment (MCI) screening. ... -
Dementia Prevalence in Greece
(2018)Introduction: Study of the epidemiology of dementia to gain insight into putative predisposing and prophylactic factors is the first step toward establishing effective preventive and therapeutic strategies for this ... -
Dual reproductive cost of aging in male medflies: Dramatic decrease in mating competitiveness and gradual reduction in mating performance
(2011)Although age-based effects on the reproductive success of males have been reported in several animal taxa the cost of aging on male mating success in lekking species has not been fully explored. We used the Mediterranean ... -
The effects of aging, physical training, and a single bout of exercise on mitochondrial protein expression in human skeletal muscle
(2012)Aging results in a significant decline in aerobic capacity and impaired mitochondrial function. We have tested the effects of moderate physical activity on aerobic capacity and a single bout of exercise on the expression ... -
Effects of an Individualized Active Aging Counseling Intervention on Mobility and Physical Activity: Secondary Analyses of a Randomized Controlled Trial
(2020)Objectives: The aim of this study was to report preplanned secondary analyses of the effects of a 12-month individualized active aging counseling intervention on six mobility and physical activity outcomes. Methods: A ... -
Electronic recording of lifetime locomotory activity patterns of adult medflies
(2022)Age-specific and diurnal patterns of locomotory activity, can be considered as biomarkers of aging in model organisms and vary across the lifetime of individuals. Τhe Mediterranean fruit fly (medfly), Ceratitis capitata, ... -
Exploring the association between subjective cognitive decline and frailty: the Hellenic Longitudinal Investigation of Aging and Diet Study (HELIAD)
(2020)Background: Subjective cognitive decline (SCD) refers to self-evaluations of impairment in cognitive functions in the absence of objective deficits. Frailty is a multidimensional syndrome that results in increased ... -
Exploring the Impact of Shame on Health-Related Quality of Life in Older Individuals
(2021)Purpose: To explore the relationship between shame, ageing, physical disease, and quality of life in Greek older people. Design and Methods: A cross-sectional design using a stratified random cluster sample of older adults ... -
Feeding behavior during long-term hexarelin administration in young and old rats
(2008)Ghrelin, a 28-amino-acid peptide isolated from the stomach, is the natural ligand of the GH-secretagogues receptor-la (GHS-R1a) and, so far, the only discovered circulating appetite-stimulating hormone. Similarly to ghrelin, ...
