A sort of biochemical scaffold for a compound that enables blood pressure to be low, heart bypass grafts to remain open and nerves to communicate has been identified by Medical College of Georgia researchers.
Dr. Richard C. Venema (left) and Dr. John D. Catravas have received American Heart Association and National Institutes of Health funding to study a biochemical scaffold they have discovered that helps keep blood pressure low and heart bypass grafts open.
A process called co-localization looks for the presence of two key proteins in the scaffold the researchers found; the antibody for heat shock protein 90 is labeled green and the one for sGC is labeled red. The yellow images show the proteins are found together in the living endothelial and smooth muscle cell. The left side shows the proteins in the endothelial cell and the right shows a smooth muscle cell.
Researchers say identifying the framework for how these and other very positive health benefits occur should help them find ways to augment the benefits and identify new treatments for cardiovascular disease, which may result when the support structure falls apart.
"Its a whole new ball game," Dr. John D. Catravas, director of the Vascular Biology Center, said of the findings which contradict previous understanding of how the compound, cyclic GMP, which also helps keep blood vessels open and enables penile erection, is ultimately produced.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
