Wiener Chemiker entwickeln eine simple Methode der Polaritätsumkehr

Die Arbeitsgruppe um den Chemiker Nuno Maulide von der Universität Wien hat eine neue Methode der Bindungsknüpfung zwischen zwei Kohlenstoffatomen entwickelt. Dabei wird die natürliche Polarität der reagierenden Gruppe durch simples Reaktionsdesign umgekehrt und macht somit den Weg frei für völlig neue Reaktionen. Darüber hinaus konnten die Forscher zeigen, dass sich durch diese Innovation bekannte Synthesewege bedeutend verkürzen lassen. Die Ergebnisse erscheinen aktuell im renommierten Fachmagazin “Angewandte Chemie”.

Vitamin D deficiency is associated with a substantially increased risk of dementia and Alzheimer’s disease in older people, according to the most robust study of its kind ever conducted.

An international team, led by Dr David Llewellyn at the University of Exeter Medical School, found that study participants who were severely Vitamin D deficient were more than twice as likely to develop dementia and Alzheimer’s disease.

The team studied elderly Americans who took part in the Cardiovascular Health Study. They discovered that adults in the study who were moderately deficient in vitamin D had a 53 per cent increased risk of developing dementia of any kind, and the risk increased to 125 per cent in those who were severely deficient.
