Telomere length (TL), a marker of cellular aging, has been studied in adults with regard to its connection to cognitive function. However, little is known about the association between TL and cognitive development in children. This study investigated the interplay between TL and cognitive functioning in 283 Belgian children aged four to six years of the Environmental Influence on Aging in Early Life (ENVIRAGE) birth cohort. Child leukocyte TL was measured using qPCR, while cognitive functioning, including attention and memory, was assessed using the Cambridge Neuropsychological Test Automated Battery (CANTAB). Linear regression models were employed to examine the association between TL and cognitive outcomes, adjusting for potential confounders. We found an inverse association between TL and the spatial errors made during the Motor Screening task ( = 0.017), indicating a higher motor accuracy in children with longer telomeres. No significant associations were found between TL and other cognitive outcomes. Our results suggest a specific link between TL and motor accuracy but not with the other cognitive domains.

Non-small cell lung cancer (NSCLC), half of which are lung adenocarcinoma (LUAD), is one of the most widely spread cancers in the world. Telomerase, which maintains telomere length and chromosomal integrity, enables cancer cells to avoid replicative senescence. When telomerase is inhibited, cancer cells' senescence began, preventing them from growing indefinitely.

Background: Physiological changes, including metabolic and cellular aging, as well as increased inflammation, occur in people living with dementia (PWD). While there is existing evidence in other populations suggesting that exercise may improve physiological outcomes, their impact in PWD remains unclear. This randomized controlled trial (RCT) aimed to assess the effects of exercise on serum levels of metabolic aging, cellular aging, and inflammatory blood biomarkers relative to usual care alone in PWD.

Background: The Down Syndrome (DS), also referred to as trisomy of chromosome 21, is a prevalent cause of intellectual disability and also contributes to the acceleration of aging, among other developmental and health concerns. Certain pathological characteristics shared by DS and Alzheimer's Disease (AD) indicate similar commonalities. This study aims to unravel the relationship between the canonical Wnt/pathway, the amyloid precursor protein processing, the telomere shortening in DS individuals.

They also have declines in physical function and heightened fall-risk. Understanding the physiologic factors that influence physical decline and fall-risk in PWD is vital to assess and prevent adverse health outcomes, such as future falls.

Exercise is a potentially effective intervention for SIVCI. However, the mechanisms through which exercise promotes brain health and cognitive function are not well understood.
