A common antibacterial and antifungal ingredient used in mouthwashes and tooth paste may have another positive medicinal use: protection against skin cancer.
According to new studies, sanguinarine was shown to enhance production of proteins that induce cell death, or apoptosis, in cells damaged by ultraviolet-B (UVB) radiation. The alkaloid also restricts skin cell production of other pro-proliferation proteins. "This natural compound may protect skin from cells that acquire the genetic damage caused by UV radiation from advancing toward cancer," said Nihal Ahmad, assistant professor, Department of Dermatology, the University of Wisconsin, Madison. "It is conceivable that sanguinarine may be used as a chemopreventive agent against skin cancer when used topically, supplemented with a sun screen."
Ahmad studies with sanguinarine were presented at the Third Annual American Association for Cancer Research International Conference on Frontiers in Cancer Prevention Research held here from October 16-20. Sanguinarine is an alkaloid present in the bloodroot plant, and is considered to have anti-bacterial, antifungal and anti-inflammatory properties. Sanguinarine is used widely in toothpastes and mouthwashes for the prevention of inflammatory conditions such as gingivitis.

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...
'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...
