Superoxide dismutase activity enabled by a redox-active ligand rather than metal. Nature Chemistry, 2018; DOI: 10.1038/s41557-018-0137-1

Scientists discover new protection against oxidative stress. Ageing and a low life expectancy are caused, at least partly, by oxidative stress. A team of researchers led by Prof. Dr. Ivana Ivanovi-Burmazovi from the Chair of Bioinorganic Chemistry at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), together with researchers from the USA, have discovered that zinc can activate an organic molecule, helping to protect against oxidative stress.

Zinc is a trace mineral we need in order to remain healthy. FAU researchers working together with Prof. Dr...

CDKN1B/p27 is localized in mitochondria and improves respiration-dependent processes in the cardiovascular system—New mode of action for caffeine. PLOS Biology, 2018; 16 (6): e2004408 DOI: 10.1371/journal.pbio.2004408

A new study shows that a caffeine concentration equivalent to four cups of coffee promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage. Caffeine consumption has been associated with lower risks for multiple diseases, including type II diabetes, heart disease, and stroke, but the mechanism underlying these protective effects has been unclear.

A new study by Judith Haendeler and Joachim Altschmied of the Medical Faculty, Heinrich-Heine-University and the IUF-Leibniz Research Institute for Env...

3-4 cups of Coffee a day linked to Longer Life

Three or 4 cups a day confers greatest benefit, except in pregnancy and for women at risk of fracture. Drinking coffee is “more likely to benefit health than to harm it” for a range of health outcomes, say researchers in The BMJ today. They bring together evidence from over 200 studies and find that drinking 3 to 4 cups of coffee a day is associated with a lower risk of death and getting heart disease compared with drinking no coffee. Coffee drinking is also associated with lower risk of some cancers, diabetes, liver disease and dementia.

However, they say drinking coffee in pregnancy may be associated with harms, and may be linked to a very small increased risk of fracture in women...
