Scientists have developed a new and fast method for making biological ‘chips’ – technology that could lead to quick testing for serious diseases, fast detection of MRSA infections and rapid discovery of new drugs. Protein chips – or ‘protein arrays’ as they are more commonly known – are objects such as slides that have proteins attached to them and allow important scientific data about the behavior of proteins to be gathered.

Graduated compression stockings were used incorrectly in 29 percent of the patients and sized incorrectly in 26 percent of the patients according to new research.
