Subfertility reflects accelerated ovarian ageing.

BACKGROUND The aim of the study was to explore the extent to which accelerated ovarian ageing may lead to subfertility early in reproductive life and eventually cause early menopause. METHODS The population studied (n = 2393) never used oral contraceptives, hormone replacement therapy or an intrauterine device. Logistic regression analyses were performed using age at menopause as proxy for ac...

Accelerated Ageing of Aluminum Electrolytic Capacitor

Electrolytic capacitors are extensively used in filtering and power decoupling in power electronic converters. Low cost and high energy density of these capacitors make them popular. However, these capacitors degrade with age due to heating and evaporation of electrolyte. This process may take about 2 to 7 years depending on the application, ambient conditions and capacitor construction. This p...

Anxiety disorders and accelerated cellular ageing.

BACKGROUND Anxiety disorders increase the risk of onset of several ageing-related somatic conditions, which might be the consequence of accelerated cellular ageing. AIMS To examine the association between anxiety status and leukocyte telomere length (LTL) as an indicator of cellular ageing. METHOD Data are from individuals with current (n = 1283) and remitted (n = 459) anxiety disorder, and...
