A substance similar to a drug used in the treatment of Parkinson’s disease blocks the stimulating effects of cocaine and could potentially be used to develop drug therapy for cocaine abuse, new research shows.
In an article published in the February 23, 2005, issue of The Journal of Neuroscience, Jonathan Katz and his colleagues at the National Institute on Drug Abuse (NIDA) report the results of experiments showing that mice treated with a substance similar to the drug benztropine did not show any of the typical hyperactive behavior when later injected with cocaine. This effect wore off after a day.
Cocaine produces intense feelings of euphoria by increasing the amount of dopamine that is sent from one neuron to another within the brain reward system. Dopamine signals pleasure and reward by binding to receptors on the receiving neurons, after which it is reabsorbed for later use by a protein that transports it back into the sending neuron. But cocaine blocks the mechanism that transports dopamine, causing it to build up and send an unceasing message of pleasure – the cocaine high.

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...
