The Biological Age in British Agricultural Virology, 1920s-1960s
… and methods did not fully displace biological or natural history-based approaches to virus research. Recent histories of molecular biology and virology have centred around two perspectives: first, the study of model organisms such as tobacco mosaic virus through experimentation, and …

EVIDENCE SUPPORTING THE UTILITY OF BLOOD CELL RESPIRATORY CAPACITY AS A SYSTEMIC MARKER OF MITOCHONDRIAL HEALTH AND BIOLOGICAL AGE
… mitochondria are implicated in nearly all age-related diseases, currently there is no clinically useful measure of systemic mitochondrial health. Multiple lines of evidence suggest that blood cells may recapitulate mitochondrial function systemically, but there is a gap in the knowledge as …

Relationships between the chronological and biological age, and physical performance of elite youth invasion games players during the course of a season
Purpose: To investigate the influence of biological age on the physical performance of elite youth athletes, whilst validating current methods of measuring maturity levels. Methods: A sample of one hundred and ninety one male elite youth athletes participated in a measurement of maturity using a …

Age estimation using epiphyseal closure at the wrist joint : an investigation of individuals of African origin, age 14 to 22 years
Age estimation techniques allow the researcher to compare chronological age, calculated from the individual's date of birth, to the level of functional and skeletal development known as biological age. This is useful in forensic cases where the age of an individual whether living or post mortem is …

Dependence of Craniofacial Growth on Stages of Cervical Vertebral Maturation and Stages of Mandibular Canine Mineralization
… of this study was to determine if pretreatment biological age, as assessed from cervical vertebral (CV) maturity and/or mandibular canine mineralization, are statistically tied to the amount of growth occurring during treatment, and if so, then if biological age has any predictive merit in …

THE EFFECT OF PHYSICAL GROWTH, BIOLOGICAL MATURATION AND ETHNICITY ON CARDIAC PRE-PARTICIPATION SCREENING IN MALE PAEDIATRIC ATHLETES
… athlete’s heart, and examine the impact of age, race, and sex on cardiac remodeling responses to competitive sport. Paediatric athletes demonstrated a greater prevalence of training-related and -unrelated ECG changes than non-athletes, with prevalence greater in black than white paediatric …

Isokinetic muscular strength and performance in youth football : relationships with age, seasonal variation and injury
… youth footballers, and the relationships with age, seasonal variation and injury. A secondary aim was to use the information gathered to target muscle strain injury prevention strategies to particular age groups and times, and evaluate the effect.The primary aim was achieved by establishing …

Realities of the Black school girl: The implication of adultification bias in K-12 schools
… Black girls as older and more mature than their biological age. Compared to their peers, Black girls are criminalized, sexualized, and dehumanized in an environment expected to provide emotional, physical, and social support- the K-12 school system. Adultified Black girls become Black women still …

Ketosis Suppression and Ageing (KetoSAge): Suppression of ketosis negatively affects multiple biomarkers associated with chronic diseases and ageing
… are among the best documented hallmarks of ageing. Ageing is typically understood in its chronological context, as the length of time that has passed since a person’s birth, whereas biological age is the measure of functional age, often measured in terms of physical and mental performance, …

On the epigenetic ageing clock in humans
… clocks are mathematical models that predict the biological age of an organism using DNA methylation data, and which have emerged in the last few years as the most accurate biomarkers of the ageing process. However, little is known about the molecular mechanisms that control the rate of such …

Promoting multi-omic rejuvenation in human and mouse somatic cells by transient reprogramming
Ageing can be defined as the gradual decline in fitness that occurs in most organisms. The ageing process is characterised by a variety of hallmarks at the cellular and molecular levels including alterations in the epigenome. Notably in the case of the epigenome, these alterations can be measured …

The Elderly in Dublin, Ireland: A Cultural Gerontological Perspective.
… examines the prevailing methods of assessing ‘age’ and the manner in which ‘ age’ is socially and culturally constructed. It deals with the various ‘ types’ of age, such as ‘biological age’ , ‘psychological age’ and so on. The conclusion is reached that since one’s ‘age’ is assessed using …

A Proximate Perspective on the Cooperative Behavior of a Lekking Passerine
… are thought to reflect an individual's biological age (as opposed to chronological age). My results show that short telomeres are associated with increased cooperative behaviors and, given that a male's cooperative behavior is reflective of their reproductive investment, suggest that …

DNA methylation: a model system for the study of ageing
… has been associated with a wide range of age-related pathologies, including type II diabetes and cancer. More recently, in humans, changes in DNA methylation at specific positions in the genome have been found to be predictive of chronological age. Interestingly, DNA methylation age is …

Ascertainment, prediction and implications of dementia diagnosis in a study of 'healthy' cognitive ageing: the Lothian Birth Cohort 1921
In the context of an ageing global population, dementia poses a significant public health challenge. While there is no cure, understanding the risks for dementia and how these may be minimised is key to reducing the impact of the disease. As life expectancy improves, increasing proportions of the …

A longitudinal study of fat mass accrual from adolescence through to emerging adulthood and its impact on cardiometabolic risk later in life
… and metabolic disease risk (CMR) at every stage of life. The prevalence of OWO nearly doubles in Canadians between childhood/adolescence and adulthood, suggesting that normal weight (NW) status is not stable through the life course and that there is a period in adulthood when fat mass (FM) …
