Rasagaline works by prolonging the effect of dopamine, a chemical that transmits signals between nerve cells in the brain. The cause of RLS is unknown, but research suggests a dopamine imbalance. Parkinson's is caused by a dopamine insufficiency.
"The hope is that Rasagaline, because it prolongs the effect of existing dopamine, instead of producing more, will not come with adverse side effects," said Dr. Shyamal Mehta, an MCG neurologist and neuroscientist. "We are trying to evaluate its safety and efficacy in treating RLS at this point. When it has been used to treat Parkinson's, it's been well-tolerated with few side effects."
Current RLS therapies include a group drugs that work by activating existing dopamine receptors, prompting the brain to make more dopamine. The problem, Mehta said, is that those drugs usually come with adverse effects, because dopamine increases feelings of euphoria.
"People taking those drugs often report behavioral problems like addiction, because the pleasure they get from things like shopping is multiplied," he said. "They can cause impulse-control problems, like gambling or hypersexuality as well. They can also cause increased sleepiness and sudden sleep attacks, which can be quite disruptive and dangerous."
Some reports also suggest decreased efficacy after extended use, as well as symptoms beginning earlier in the day.
Restless leg syndrome, which affects 10 percent of the population, is characterized by prickling or tingling in the legs and an urge to move the legs. Symptoms are more noticeable at rest, such as during bedtime or a long car ride. RLS can also cause depression and daytime sleepiness, Dr. Mehta said, and is linked to conditions including iron deficiency, renal failure, pregnancy and Parkinson's.
MCG is one of seven centers participating in the 14-week trial, which will enroll 52 participants nationally. Participants must have an RLS diagnosis and be off any related medications for at least 30 days before the study.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
