Abstract Eighty-seven red wines produced from grapes of the grape variety Gaglioppo Calabria region (vintage 2009) were analysed by standard methods after 4 and 120 months ageing. So, a total 29 selected starters Saccharomyces cerevisiae —3 wild type, 12 monoclonal cultures, 14 hybrids—inoculated in triplicate studied for their effects on colour natural antioxidant power keeping wine. Wine agei...

The skin is the part of the human body most vulnerable to ultraviolet (UV) radiation. The spectrum of the negative effects of UV radiation on the skin ranges from acute erythema to carcinogenesis. Between these extreme conditions, there are other common skin lesions, e.g., photoageing. The aim of this study was to assess the skin for signs of photoageing in a group of 52 men occupationally expo...

1. AGEING Ageing is an integral, natural part of life. The way in which we grow old and experience this process, our health and functional ability all depend not only on our genetic makeup, but also (and importantly) on what we have done during our lives; on what sort of things we have encountered in the course of our lifetime; on how and where we have lived our lives. Lifespan is defined as th...

Natural ageing responses of duplex structured Mg-6%Li and Mg-6%Li-6%Zn-1.2%Y alloys have been investigated. Microstructural analyses revealed that the precipitation and coarsening process of α-Mg particles could occur in β-Li phases of both two alloys during ageing process. Since a certain amount of Mg atoms in β-Li phases were consumed for the precipitation of abundant tiny MgLiZn particles, t...

The Belgian mathematician Quetelet (1835) in his treatise on human development wrote ‘Man is born, grows up and dies according to laws which have never been properly investigated either as a whole or in the mode of their mutual reactions’, thereby reinforcing our awareness that ageing is an inevitable and natural process in life but that this process is not well-understood. Quetelet (1 835) mad...

In many long-lived vertebrates (including humans), adult males have shorter lifespans than adult females, partly as a result of higher annual rates of mortality in males and partly owing to sex differences in the rate of ageing. A probable explanation of the evolution of sex differences in ageing is that, in polygynous species, intense intrasexual competition between males restricts the number ...

Sex differences in lifespan exist world-wide, with women outliving men by more than a decade in some countries. The gender gap is not a uniquely human phenomenon; most sexually reproducing species examined show sex differences in patterns of ageing, yet a comprehensive explanation does not exist. Here, we discuss how ageing responds to natural selection on traits that arise as a consequence of ...
