Vessel wall cells and blood cells have been found to release cell particles which can damage blood vessels. This was demonstrated in laboratory experiments carried out by Marja van Wijk during her doctoral research at the University of Amsterdam. Poorly functioning blood vessels play a role in pre-eclampsia.
For her research (conducted at the Academic Medical Centre, University of Amsterdam) Van Wijk isolated blood vessels from pieces of tissue taken from pregnant women. She placed the blood vessels in a solution of microparticles isolated from the blood of pregnant women with and without pre-eclampsia. A so-called wire myograph was then used to measure the functioning of the blood vessels.
Vessels in a solution of affected microparticles were found to function less well than vessels with healthy particles. Which microparticles or parts thereof are responsible for the vessel damage is not clear. Exactly how the particles are formed must also be investigated.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
