Higher CCSVI prevalence confirmed in MS, but meaning of findings remains unclear
BUFFALO, N.Y. -- A just released study on the relationship between multiple sclerosis (MS) and chronic cerebral venous insufficiency (CCSVI), a narrowing of the extracranial veins that restricts the normal outflow of blood from the brain, found that CCSVI may be a result of MS, not a cause.

Learn more quickly by transcranial magnetic brain stimulation
What sounds like science fiction is actually possible: thanks to magnetic stimulation, the activity of certain brain nerve cells can be deliberately influenced. What happens in the brain in this context has been unclear up to now. Medical experts from Bochum under the leadership of Prof. Dr. Klaus Funke (Department of Neurophysiology) have now shown that various stimulus patterns changed the activity of distinct neuronal cell types. In addition, certain stimulus patterns led to rats learning more easily. The knowledge obtained could contribute to cerebral stimulation being used more purposefully in future to treat functional disorders of the brain. The researchers have published their studies in the Journal of Neuroscience and in the European Journal of Neuroscience.

Breakthrough on cystic fibrosis 1 step closer as new research alliance formed
McGill University and GlaxoSmithKline plc (GSK) have signed a collaboration agreement to develop a potential breakthrough approach to treat cystic fibrosis, a fatal genetic disease. The trans-Atlantic effort between researchers from McGill's Faculty of Medicine and their GSK collaborators in the UK, will focus on developing molecules that could treat the disease by correcting the dysfunction caused by the mutated gene. This revolutionary approach will be a departure from current treatments, which only manage the symptoms or complications of the disorder. The collaborative research is co-sponsored by the Canadian Institutes of Health Research (CIHR).

Hormonal therapy for older, pregnant horses?
Most miscarriages in horses results at very early stages of pregnancy (within about three weeks) and it is generally believed that the primary cause is that the foetus grows or develops too slowly: smaller than normal embryos have a higher chance of being lost then normally sized ones. It is not clear whether low concentrations of progesterone lead to slower embryonic development but nevertheless the progestin altrenogest is routinely used to treat mares that frequently suffer miscarriages. Aurich's group has now found that altrenogest treatment has no effect on the levels of luteinizing hormone (LH) or progesterone, hormones that are known to be important in maintaining pregnancy. Furthermore, treatment does not influence the ease with which the mares became pregnant, nor does it affect the size of the vesicles housing the embryos, at least for the first 22 days after conception. However, the researchers did notice that at 20 days after conception the embryonic vesicles are smaller if the mares are older. They also found that the foetuses of older mares grow significantly more slowly after this period, although if the mares are treated with altrenogest their foetuses grow at the normal rate.

In the lab, engineer's novel liquid provides a solid fix for broken bones
Here's the vision: an elderly woman comes into the emergency room after a fall. She has broken her hip. The orthopaedic surgeon doesn't come with metal plates or screws or shiny titanium ball joints. Instead, she pulls out a syringe filled with a new kind of liquid that will solidify in seconds and injects into the break. Over time, new bone tissue will take its place, encouraged by natural growth factors embedded in the synthetic molecules of the material.

Proof that a gut-wrenching complaint -- irritable bowel syndrome -- is not in your head
Irritable bowel syndrome makes life miserable for those affected -- an estimated ten percent or more of the population. And what irritates many of them even more is that they often are labeled as hypochondriacs, since physical causes for irritable bowel syndrome have never been identified. Now, biologists at the Technische Universitaet Muenchen (TUM) have shed new light on the matter: They have discovered mini-inflammations in the mucosa of the gut, which upset the sensitive balance of the bowel and are accompanied by sensitization of the enteric nervous system.

Special horseshoes measure acceleration in horses
The most frequent injuries that horses suffer are derived from pressure exerted by riders, and knowing which forces are involved when horses move can prove highly informative when considering treatment for such injuries. A team of scientists from Wageningen University, led by Professor Johan van Leeuwen, has carried out studies both into the advantages of different rider techniques in reducing injury risk, and into the benefits of a method of equine rehabilitation. By using computer modelling and specialist horseshoes to measure acceleration, these investigations suggest that aqua-training rehabilitation is beneficial due to lower impact accelerations. However, rising trot may not be as advantageous as previously thought. Results will be presented on Monday 7th July at the Society for Experimental Biology's Annual Meeting in Marseille [Session A3].
