The early decline and loss of female fertility in humans and other species represents an evolutionary paradox. Despite being born with a vast stock of oocytes, females encounter an exhaustion of ovarian reserve and sterility half way through their natural lives. Female reproductive ageing has been proposed to proceed as an ongoing decline in ovarian reserve, determined by remaining ovarian foll...

The population of the developed world is steadily ageing. In the European Union, approximately 22% of persons are over 60 years of age and this is projected to increase to more than 27% by the year 2020. This has major implications for health care resources and the productive workforce. Ageing is accompanied by a decline in the physiological reserve of all organ systems, compromising homeostasi...

STUDY QUESTION Is there an association between the number of CGG repeats in the FMR1 gene in the normal and intermediate range and age at natural menopause? SUMMARY ANSWER The number of CGG repeats in the normal and intermediate range in the FMR1 gene was not associated with age at natural menopause. WHAT IS KNOWN ALREADY Excessive triple CGG repeats in the FMR1 gene have been widely associ...

Natural ageing has a major influence on the properties of paper, while light, heat, and humidity are environmental influences that most disrupt stability paper. This research focuses changes in straw-containing papers caused by accelerated ageing. The were made laboratory mixing straw pulp with recycled fibers different weight ratios artificially aged dry-heat treatment (thermal oxidation) UV r...

There is an age related decline in various physiological processes. Vascular ageing is associated with changes in the mechanical and the structural properties of the vascular wall, which leads to the loss of arterial elasticity and reduced arterial compliance. Arterial compliance can be measured by different parameters like pulse wave velocity, augmentation index, and systemic arterial complian...
