Rates of heart disease, stroke continue to decline in Europe

The research, which provides an update for 2014 on the burden of cardiovascular disease (CVD) in Europe, shows that death rates from CVD (diseases of the heart and blood vessels) vary enormously. For some eastern European countries, including Russia and Ukraine, the death rate from coronary heart disease for 55-60 year olds is greater than the equivalent rate in France for people 20 years older. The age adjusted CVD death rates for men and women of all ages were six-fold higher in Russia than in France. In 2010 in Russia 915 men and 517 women died per 100,000 of the population, whereas the equivalent rates in France were 150 and 87 per 100,000 respectively. …

How protein suicide assure healthy cell structures

PLK4 is one of the key proteins required to control centriole formation: in its absence centrioles fail to form, while in excess PLK4 induces the formation of an extra number of those structures. Bettencourt-Dias’ team has now identified how PLK4 controls its levels, and ultimately the number of centrioles. By performing different biochemical assays, the researchers observed that PLK4 is capable of auto-regulating its levels by adding chemical groups of phosphate to itself, which will act as a signal for destruction. However, if PLK4 kills itself too early this will prevent it from ensuring the control of centriole number. …
