Scientists recommend new type of therapeutic approach to dementia

Scientists at Charité - Universitätsmedizin Berlin have succeeded in recommending a new type of therapeutic approach to dementia. The study published in the journal Neurology shows that immune reactions against the body's own nerve cells can be the cause of advanced dementia and an appropriate immune suppressive therapy can develop with significant effectiveness.

Symposium at EuroPRevent 2012 highlights benefits of oily fish consumption

Most people, whether healthy or having cardiovascular disease (CVD), would benefit from regular consumption of oily fish, concluded speakers at the EuroPRevent 2012 meeting. While eating whole fish undoubtedly offers the optimum approach for increasing omega-3 intakes in both primary and secondary prevention, delegates heard, supplements have a major role to play in increasing omega-3 intakes for people who do not like fish.

Researchers develop five different molecular models of the voltage sensor

Every thought, every movement, every heartbeat is controlled by lightning-quick electrical impulses in the brain, the muscles, and the heart. But too much electrical excitability in the membranes of the cells can cause things like epilepsy and cardiac arrhythmia. A research group at Linköping University has now published new discoveries that can lead to new medicines for these diseases.

Stimulating specific neurons may reverse age-related memory defects

Scientists from the Florida campus of The Scripps Research Institute have shown in animal models that the loss of memory that comes with aging is not necessarily a permanent thing.

Anesthesia may affect organization of lipids in a cell's outer membrane

Why does inhaling anesthetics cause unconsciousness? New insights into this century-and-a-half-old question may spring from research performed at the National Institute of Standards and Technology.

The two sides of pain

"Pain is both a curse and a blessing", says Jürgen Sandkühler, Head of the Department of Neurophysiology at the Centre for Brain Research at the MedUni Vienna ahead of the international "Brain Awareness Week", being held from the 12th to the 16th of March. On the one hand, pain has an important protective function for humans.

Researchers determine structure of concentrative nucleoside transporter

A team of researchers at Duke University has determined the structure of a key molecule that can carry chemotherapy and anti-viral drugs into cells, which could help to create more effective drugs with fewer effects to healthy tissue.

Unknown 'root' extension in hair cells of the inner ear

The hair cells of the inner ear have a previously unknown "root" extension that may allow them to communicate with nerve cells and the brain to regulate sensitivity to sound vibrations and head position, researchers at the University of Illinois at Chicago College of Medicine have discovered. Their finding is reported online in advance of print in the Proceedings of the National Academy of Sciences.

Study shows how hydra respond to light in the absence of eyes

In the absence of eyes, the fresh water polyp, Hydra magnipapillata, nevertheless reacts to light. They are diurnal, hunting during the day, and are known to move, looping end over end, or contract, in response to light.

Ion channels assembled in different combinations distinguish temperatures

The winter sun feels welcome, but not so a summer sunburn. Research over the past 20 years has shown that proteins on the surface of nerve cells enable the body to sense several different temperatures. Now scientists have discovered how just a few of these proteins, called ion channels, distinguish perhaps dozens of discrete temperatures, from mildly warm to very hot.

Scientists discover that sperm do not function like olfactory cells

According to a 2003 study by German and American scientists, a component of the Lily of the Valley scent known as Bourgeonal alters the calcium balance of human sperm and attracts the sperm. The "Lily of the Valley phenomenon" - also the title of a book about smelling - was born as a result of this discovery that sperm act as swimming olfactory cells which follow a "scent trail" laid by the egg. However, a detailed explanation for the Lily of the Valley phenomenon remained illusive as neither Bourgeonal nor other scents could be identified in the female sex organ.

Evolutionary forces encourage diversity in the active surfaces of venomous toxins

For snakes, spiders, and other venomous creatures, the "business end," or active part, of a toxin is the area on the surface of a protein that is most likely to undergo rapid evolution in response to environmental constraints, say researchers from Ben Gurion University in Israel.

Chemists build light-controlled neural inhibitor

The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and Bordeaux, have now shown in laboratory experiments that it is possible to inhibit the activity of pain-sensitive neurons using an agent that acts as a photosensitive switch. For the LMU researchers, the method primarily represents a valuable tool for probing the neurobiology of pain.
