Fibrin gel matrix-based vessel ready for test transplantation after only two weeks in culture
The search for a stable, renewable source of blood vessels, especially for potential use in heart bypass surgery, has reached a milestone at the State University of New York at Buffalo. A multi-disciplinary team at SUNY Buffalo designed tissue engineered blood vessels (TEVs) using a matrix of vascular smooth muscle embedded in fibrin gels. After only two weeks in culture, the TEVs showed the strength and resiliency necessary for implantation. Even more exciting, 15 weeks after implantation, the fibrin-based TEVs "exhibited remarkable remodeling with considerable production of collagen and elastin, and significantly increased mechanical strength (and) physiological levels of blood flow and vasoreactivity," according to a paper published online in the American Journal of Physiology-Heart and Circulatory Physiology.
Currently, blood vessels are usually "harvested" from the patient’s own leg, often causing pain and discomfort, as well as extra surgical steps. So the need for a source of strong, yet elastic -- and physiologically responsive – replacement blood vessels has been the subject of laboratory searches and experimentation for decades.

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.

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...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
