Defeating high blood pressure may be a matter of a little molecular manipulation.
Some drugs for hypertension, such as so-called ACE inhibitors, block specific receptor proteins on the cell. But researchers at Jefferson Medical College instead have looked to a certain molecular pathway called the Gq signaling pathway, showing that it plays an important role in developing various models of hypertension. The work might lead to new insights into the roots of hypertension, and eventually, the scientists believe, novel therapies.
Andrea Eckhart, Ph.D., associate professor of medicine at Jefferson Medical College of Thomas Jefferson University in Philadelphia and her co-workers focused on drugs known as alpha-adrenergic receptor blockers and angiotensin II receptor blockers (including ACE inhibitors), which block angiotensin over-production, and which can lead to high blood pressure. Both of these receptors normally bind to a class of receptors called Gq, which ultimately leads to hypertension.

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...
