Background The relationship between sleep parameters and longitudinal shortening of telomere length is unclear. This study aimed to investigate the leukocyte (LTL) over two years. Method Among participants in validation cohort Korea Brain Aging Study for Early Diagnosis Prediction Alzheimer’s Disease, who measured both baseline follow-up (two years later) LTL were analyzed. They dichotomized ac...

Background: Telomeres are particular sequences of DNA located at the end of the eukaryotic chromosomes that are essential for genome integrity. Telomere length in spermatozoa differs among males, as well as spermatozoa. Also, decreased telomere length in spermatozoa of infertile men is associated with the reduction of fertility potential and embryo quality. Density gradient centrifugation (DGC)...

Telomere length and the rate of telomere shortening have been suggested as particularly useful physiological biomarkers of the processes involved in senescent decline of somatic and reproductive function. However, longitudinal data on changes in telomere length across the lifespan are difficult to obtain, particularly for long-lived animals. Quasi-longitudinal studies have been proposed as a me...
