A manmade protein with a tail of amino acids delivered to target cells can dramatically reduce blood vessel growth that obstructs vision or feeds a tumor, researchers have found.
This new approach to inhibiting blood vessel growth, or angiogenesis, delivers "intraceptors" that sequester VEGF, a "linchpin" protein needed to make blood vessels, says Dr. Balamurali K. Ambati, corneal specialist at the Medical College of Georgia and corresponding author on the study.
In a test tube as well as animal models for corneal injury and the deadly skin cancer, melanoma, MCG researchers have reduced destructive blood vessel proliferation by up to two-thirds. Findings are published in the May issue of Investigative Ophthalmology & Visual Science. "We have a promising new preclinical approach to treat conditions that involve blood vessel formation," says Dr. Ambati. These include corneal injury, the blinding wet form of macular degeneration, diabetic retinopathy and tumors, which need blood and oxygen to survive. Other angiogenesis inhibitors in use or under study target VEGF (vascular endothelial growth factor) after it has moved outside the cell, says Dr. Ambati, reducing new blood vessel growth by 30 percent to 50 percent.

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...
