Clinical pharmacologists at Heidelberg University Hospital have achieved major progress for improving the reliability of drugs. In a pharmacological study, they showed for the first time that interactions between drugs can be detected with minute doses in the range of nanograms.
In the published study, the team investigated the interaction between the sedative midazolam, which is metabolized in the liver by the protein cytochrome P450 3A, and the fungicide ketoconazole, a well-known inhibitor of this cytochrome. The inhibition of the cytochrome and, in turn, the reduced degradation of midazolam, were already precisely measured in the nanogram dose. This interaction in particular plays an important role for patients who need to take several drugs simultaneously. Many drugs inhibit this enzyme, which metabolises around half of all regularly used medicines. However, if a drug is degraded too slowly, at normal doses, it accumulates in the body and, in the worst case, can cause toxicity.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
