FDA approves Bystolic, a novel beta blocker
The US Food and Drug Administration has approved Bystolic (nebivolol) for the treatment of hypertension, also known as high blood pressure. Bystolic works differently than many older beta blockers in that it is preferentially beta 1 selective at doses less than or equal to 10 mg, meaning it selectively blocks the effects of adrenaline at the heart. In addition, Bystolic vasodilates -- or widens and expands -- the blood vessels. (2007-12-18)

Here's something that will raise your blood pressure
The apelin receptor (APJ) has been presumed to play an important role in the contraction of blood vessels involved in blood pressure regulation. A University of Tsukuba-led research team found that APJ was closely associated with hypertension through effects on vascular smooth muscle cells in laboratory mice. In addition, APJ worked synergistically with the α1A-adrenergic receptor to cause vasoconstriction. These results may help to understand blood pressure regulation and support therapies for vascular diseases. (2019-11-01)

ID microstructure of stock useful in financial crisis
A German team from the University of Duisburg-Essen have analysed the statistical regularities and irregularities in the recent order flow of 96 different NASDAQ stocks. Since prices are strongly correlated during financial crises, they evolve in a way that is similar to what happens to nerve signals during epileptic seizures. The findings of the Duisburg-Essen group, published in EPJ B, contribute to modelling price evolution,and could ultimately be used to evaluate the impact of financial crises. (2017-11-22)
