Deguelin may inhibit growth of Akt, an essential molecule in the promotion of precancer
The use of deguelin, a natural plant extract most commonly used as an insecticide in Africa and South American, inhibits the growth of precancerous and cancerous lung cells, with no toxic effects on normal cells, according to a study presented today at the first annual Frontiers in Cancer Prevention Research meeting convened by the American Association for Cancer Research. The role of deguelin as an inhibitor of Akt activation has clinical implications, especially in non-small cell lung cancer (NSCLC), where constant activation of Akt occurs. Akt, or protein kinase B, is recognized as one of the most important molecules that promotes the survival of tumor cells by playing the critical role of controlling the balance between survival and apoptosis (programmed cell death).
The study investigated the effects of deguelin on cells representing different stages of lung cancer, and characterized the ways in which deguelin works on precancerous and cancerous human bronchial epithelial (HBE) cells. Deguelin has been isolated from plants such as Mundulea sericea (Leguminosae), which is native to Africa and South America.

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...
