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.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
