caffeine and anxiety

There is no limit to how far molecular biology is extending to explain biological phenomenon. This is a brilliant example of hw such studies can explain. Some people are very susceptible to caffeine and become anxious. Others aren’t. This paper explains a possible reason. Association between ADORA2A and DRD2 Polymorphisms and Caffeine-Induced AnxietyCaffeine produces mild…

anti-ageing genes and cancer

This is an interesting Perspective on turning anti-ageing genes against cancer. In such fluid states nutrition is bound to have a role. Recent studies in diverse organisms implicate proto-oncogenic pathways, including insulin-like growth factor-I (IGF-I), Ras and AKT/protein kinase B in the ageing process. Although IGF-I is thought to contribute to cancer by promoting growth…

age and cancer

It is so easy to be simplistic about the aetiology of cancer. This review is of great interest in this respect. Read the full article and be cautious in future.Two paradigms central to geroscience research are that aging is associated with increased oxidative stress and increased cancer risk. Therefore, it could be deduced that cancers…
