Researchers have defined five categories of diabetes patients, rather than the longstanding basic division into type 1 and type 2.

An IPO for the health care business of Munich, Germany-based Siemens AG has been a long-time coming. Almost three years ago in May 2014, the German conglomerate laid out a five year plan to get it through 2020.

This cellular polarity results in a specific shape that includes a 'nose' that invades tissue and then works to thrust the CTC into it and out of the blood stream.
