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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
