Research helps physicians understand rare form of ataxia that causes patients to appear drunk at times
Scientists at Oregon Health & Science University are the first to produce an animal model for episodic ataxia. The condition causes patients to suffer bouts of extreme clumsiness where they have balance, speech and motor difficulties. The research helps scientists better understand this rare and intriguing disorder. It may also help provide valuable information for improved, targeted drugs for treatment. The research is printed in the April edition of the journal Nature Neuroscience. It was conducted in conjunction with researchers at the Portland Veterans Affairs Medical Center.
"By developing a mouse model for episodic ataxia, we now have a valuable tool to better understand and treat the disease," said James Maylie, Ph.D., a professor of obstetrics and gynecology in the OHSU School of Medicine. "We have already used this animal model to observe and learn more about cellular mechanisms behind the disease. These disease-linked cells are located in the cerebellum, a portion of the brain involved in motor coordination."
The research also helps explain how a medication commonly used to treat patients works. "Acetazolamide is often given to patients with episodic ataxia," Maylie said. "Using these mice models, we were able to establish how acetazolamide acts at a cellular level to combat the disorder, something that was previously unknown."

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
