Modeling cerebral hemodynamic parameters vs. age
<p>These data were consecutively collected at the Wroclaw University of Science and Technology from June 2014 to June 2015.</p> <p>The study participants were recruited and divided into two distinct groups. The younger group included patients aged from 18 years (only adults, no children or adolescents) up to 30 years. The older group (> 40 years) has been designed as a subgroup to analyze more pronounced changes in structural and functional changes in cerebral arteries.</p> <p>Exclusion criteria were patients with any vascular risk factors (hypertension, smoking, diabetes mellitus, dyslipidemia, and cardiovascular or neurological diseases). None of the volunteers was under medications. Before the measurement was performed, the participants were instructed to abstain from consuming caffeine and alcohol and to avoid engaging in intensive exercise for at least 12 hours.</p> <h3><strong><span>Funding</span></strong></h3> <p><span><strong><span>SONATA 18 </span></strong></span><span><strong><span>UMO-2022/47/D/ST7/00229 </span></strong></span><span>National Science Centre, Poland</span></p> <p><span><strong><span>SONATA-BIS UMO-2013/10/E/ST7/00117 </span></strong></span><span><span>National Science Centre, </span></span><span>Poland</span></p> <p><strong>If using this data, please refer to the following article:</strong></p> <p>Uryga A, Czosnyka M, Robba C, Nasr N, Kasprowicz M.

COVID-19 PHAC Agent-Based Model for age-stratified intervention and herd immunity study
<p>The PHAC agent-based model was used to explore the progression of the COVID-19 epidemic under three intervention scenarios (infection-preventing vaccination, illness-preventing vaccination and shielding) in individuals above three age thresholds (≥45, ≥55 and ≥65 years) while lifting shutdowns and physical distancing in the community. This data repository contains the PHAC modelling code in Anylogic used for this study. </p>
Incubation temperature and physiological aging in the zebra finch
<p>In birds, incubation temperature has received increased attention as an important source of phenotypic variability in offspring. A lower than optimal incubation temperature may negatively affect aspects of nestling physiology, such as body growth and energy metabolism. However, the long-term effects of sub-optimal incubation temperature on morphology and physiology are not well understood. In a previous study, we showed that zebra finches from eggs incubated at a low temperature (35.9°C) for 2/3 of the total incubation time suffered a lower post-fledging survival compared to individuals that had been incubated at higher temperatures (37.0 and 37.9°C). In the present study, we investigated whether these variations in incubation temperature could cause permanent long-lasting differences in body mass, body size, or basal metabolic rate. Furthermore, we tested whether the observed differences in survival between treatment groups would be reflected in the rate of physiological deterioration, assessed through oxidative damage and decreased metabolic rate with age (i.e. 'metabolic aging'). Incubation temperature did not significantly affect embryonic or nestling body growth and did not influence final adult body mass or body size. Nor was there any long-term effect on basal metabolic rate. Birds from eggs incubated at the lowest temperature experienced an accumulation of oxidative damage with age, although this was not accompanied by an accelerated rate of metabolic aging. The present results suggest that the low survival in these birds was possibly mediated by increased oxidative stress, but independent of body growth and the basal metabolic rate.</p>

Data on paternal age and sperm production of the progeny
<p>Parental age has profound consequences for offspring's phenotype. However, whether patrilineal age affects offspring sperm production is unknown, despite the importance of sperm production for male reproductive success in species facing post-copulatory sexual selection. Using a longitudinal dataset on ejaculate attributes of the houbara bustard, we showed that offspring sired by old fathers had different age-dependent trajectories of sperm production compared to offspring sired by young fathers. Specifically, they produced less sperm (-48%) in their first year of life, and 14% less during their lifetime. Paternal age had the strongest effect, with weak evidence for grandpaternal or great grandpaternal age effects. These results show that paternal age can affect offspring reproductive success by reducing sperm production, establishing an intergenerational link between aging and sexual selection.</p>
