Adenosine therapy reduces seizures and progression of epilepsy

2013-07-25
(Press-News.org) Epilepsy is characterized by recurrent seizures that present in many different ways. In some cases epileptic patients exhibit a progressive increase in both frequency and severity of seizures. Epigenetic changes such as DNA methylation have recently been implied as an underlying cause of several neurologic disorders, including epilepsy. In this issue of the Journal of Clinical Investigation, Detlev Boison and colleagues at Legacy Research show an increase of DNA methylation in the hippocampi of epileptic animals. They found that increased methyation corresponded with a decrease of adenosine (ADO), which is a known anticonvulsant. The authors used bioengineered implants to transiently deliver ADO to the brains of epileptic rats. Targeted ADO delivery to the brain reversed DNA hypermethylation and resulted in a decrease in seizures and prevented epilepsy progression. These data indicate that therapies aimed at reducing DNA methylation in the brain have potential for the treatment and prevention of epilepsy.

NIH study uncovers a starring role for supporting cells in the inner ear

2013-07-25
Researchers have found in mice that supporting cells in the inner ear, once thought to serve only a structural role, can actively help repair damaged sensory hair cells, the functional cells that turn vibrations into the electrical signals that the brain recognizes as sound. The study in the July 25, 2013 online edition of the Journal of Clinical Investigation reveals the rescuing act that supporting cells and a chemical they produce called heat shock protein 70 (HSP70) appear to play in protecting damaged hair cells from death. Finding a way to jumpstart this process ...

Secret of plant geometry revealed

2013-07-25
Researchers at the University of Leeds have discovered how plants set the angles of their branches. While the other principle features governing the architecture of plants such as the control of the number of branches and positioning around the main shoot are now well understood, scientists have long puzzled over how plants set and maintain the angle of their lateral branches relative to gravity. The mechanism is fundamental to understanding the shape of the plants around us: explaining how, for instance, a young Lombardy poplar sends its branches up close to the vertical ...

Bad sleep around full moon is no longer a myth

2013-07-25
Many people complain about poor sleep around full moon. Scientists at the University of Basel in Switzerland now report evidence that lunar cycles and human sleep behavior are in fact connected. The results have been published in the journal «Current Biology». The research group around Prof. Christian Cajochen of the Psychiatric Hospital of the University of Basel analyzed the sleep of over 30 volunteers in two age groups in the lab. While they were sleeping, the scientists monitored their brain patterns, eye movements and measured their hormone secretions. The findings ...

Silky brain implants may help stop spread of epilepsy

2013-07-25
Silk has walked straight off the runway and into the lab. According to a new study published in the Journal of Clinical Investigation, silk implants placed in the brain of laboratory animals and designed to release a specific chemical, adenosine, may help stop the progression of epilepsy. The research was supported by the National Institute of Neurological Disorders and Stroke (NINDS) and the National Institute of Biomedical Imaging and Bioengineering (NIBIB), which are part of the National Institutes of Health. The epilepsies are a group of neurological disorders associated ...

Study shows supplement with omega fatty acids promising for 30 million dry eye sufferers

2013-07-25
HOUSTON, TX.—July 25, 2013—Study* findings published online, ahead of print, in Cornea show that daily dietary supplementation with a unique combination of omega fatty acids (GLA, EPA and DHA) for six months is effective in improving ocular irritation symptoms and halting the progression of inflammation that characterizes moderate to severe dry eye. The multicenter, double-blind, randomized, placebo-controlled clinical trial conducted at Baylor College of Medicine and Virginia Eye Consultants evaluated 38 post-menopausal women with tear dysfunction in both eyes. Participants ...

Deciphering the air-sea communication

2013-07-25
25 July 2013 / Kiel / Moscow. Why does hurricane activity vary from decade to decade? Or rainfall in the Sahel region? And why are the trans-Atlantic changes frequently in sync? A German-Russian research team has investigated the role of heat exchange between ocean and atmosphere in long-term climate variability in the Atlantic. The scientists analyzed meteorological measurements and sea surface temperatures over the past 130 years. It was found that the ocean significantly affects long term climate fluctuations, while the seemingly chaotic atmosphere is mainly responsible ...

What if quantum physics worked on a macroscopic level?

2013-07-25
Quantum physics concerns a world of infinitely small things. But for years, researchers from the University of Geneva (UNIGE), Switzerland, have been attempting to observe the properties of quantum physics on a larger scale, even macroscopic. In January 2011, they managed to entangle crystals, therefore surpassing the atomic dimension. Now, Professor Nicolas Gisin's team has successfully entangled two optic fibers, populated by 500 photons. Unlike previous experiments which were carried out with the fiber optics of one photon, this new feat (which has been published in ...
