Injections of a stimulant agent into rat brains expanded blood vessels and improved blood flow, a finding that may lead to a new, non-invasive way to prevent stroke, researchers reported in today’s rapid access issue of Circulation: Journal of the American Heart Association.
Rats treated with the growth-promoting substance granulocyte macrophage-colony stimulating factor (GM-CSF) had almost twice as much arteriogenesis, the expansion of a brain artery, after one week compared to rats given saline solution. The increase was associated with improved circulation and accumulation of cells that are thought to play a key role in artery development.
“To the best of our knowledge, this is the first report of stimulation of arteriogenesis in the brain,” say co-lead authors Ivo R. Buschmann, M.D., and Hans-Jörg Busch, M.D. Both are investigators in the Research Group for Experimental and Clinical Arteriogenesis at Albert Ludwigs University in Freiburg, Germany.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
