Scientists at Jefferson Medical College have used gene therapy to reverse the progression of Parkinson’s disease in rats. They have found that by adding a gene for an enzyme, they were able to reprogram brain circuitry and halt the deterioration of dopamine producing brain cells, one of the key problems in the disease.
“It’s not just inserting a replacement for a missing or mutated gene as a treatment for a genetic disorder,” says Michael Oshinsky, Ph.D., research assistant professor of neurology at Jefferson Medical College of Thomas Jefferson University in Philadelphia and part of the team reporting its results October 11 in the journal Science. “This is more profound. We are actually changing the brain’s circuitry as treatment for a disease.”
According to Dr. Oshinsky and Jia Luo, M.D., research associate at Jefferson Medical College of Thomas Jefferson University, in Parkinson’s, a portion of the brain called the subthalamic nucleus is overactive. These cells produce glutamate, an excitatory neurotransmitter, or chemical message carrier, into another region called the substantia nigra, which is important for the coordination of movement and where the brain chemical dopamine is made. Parkinson’s is caused by the deterioration of dopamine-producing nerve 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...
