The goal of ageing face surgery is to achieve a natural, rejuvenated, youthful appearance. Higher patient expectations and increasing deman...

Background: The mammalian oocyte has the unique feature of supporting fertilization and normal development while being able of reprogramming the nuclei of somatic cells towards pluripotency, and occasionally even totipotency. Whilst oocyte quality is known to decay with somatic ageing, it is not a given that different biological functions decay concurrently. In this study, we tested whether ooc...

Seed ageing is influenced by two environmental factors, RH and temperature. The deterioration of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. Accelerated ageing has been recognized as a good predictor of the storability of seed lots. Aged seeds show decreased vigour and produce weak seedlings that are unable to survive once re...

Hydrolytic ageing or hydrolysis is the destruction of chemical bonds by action water. Among polymers most affected are polyamides, since PA6 hygroscopic, due to amide groups. with its interesting technical applications could be found in humid environments, which probably impedes durability. The estimation modifications that undergo has attracted attention several research subjects, have recorde...
