CINCINNATI, Sept. 26, 2014 /PRNewswire-USNewswire/ -- New research shows that disrupting the molecular function of a tumor suppressor causes improper formation of a protective insulating sheath on peripheral nerves - leading to neuropathy and muscle wasting in mice similar to that in human diabetes and neurodegeneration. http://photos.prnewswire.com/prnvar/20110406/MM79025LOGO Scientists from Cincinnati Children's Hospital Medical Center report their findings online Sept. 26 in...

People with multiple sclerosis (MS) lose myelin in the gray matter of their brains and the loss is closely correlated with the severity of the disease, according to a new magnetic resonance imaging (MRI) study that appears online, September 10, in the journal Radiology. OAK BROOK, Ill. (PRWEB) September 09, 2014 People with multiple sclerosis (MS) lose myelin in the gray matter of their brains and the loss is closely correlated with the severity of the disease, according to a new magnetic...

Salk Institute Scientists hope to borrow strategy from simpler animals to repair damaged spinal cord nerves in humans Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is—while many animals have this ability, humans don't. But new research from the Salk Institute suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits. Such a feat could eventually lead to therapies for the...

NIH/National Eye Institute NIH-funded study could help improve retinal prosthetic devices In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people, the researchers say. The work was funded in part by the National Institutes of Health. Just 20 years ago, bionic...

Scientists at the Salk Institute have discovered the developmental source for a key type of neuron that allows animals to walk, a finding that could help pave the way for new therapies for spinal cord injuries or other motor impairments related to disease. The spinal cord contains a network of neurons that are able to operate largely in an autonomous manner, thus allowing animals to carry out simple rhythmic walking movements with minimal attention—giving us the ability, for example, to...

Photoreactive compounds developed by LMU scientists directly modulate nerve-cell function, and open new routes to the treatment of neurological diseases, including chronic pain and certain types of visual impairment. All modes of sensory perception are based on communication between nerve cells. Both the response to the primary stimulus and the transmission of the resulting signal depend on the function of specialized receptor proteins that are associated with the surface membranes of...

University of California - Santa Barbara Using the surface forces apparatus and an atomic force microscope, researchers at UC Santa Barbara have taken a molecular approach to myelin membrane interactions, leading to insights into demyelinating diseases, such as multiple sclerosis. Their research is published in the Proceedings of the National Academy of the Sciences. For a healthy nervous system, axons — the long projections of our nerve cells that run throughout our bodies — must...

Progressive degeneration of photoreceptors—the rods and cones of the eyes—causes blinding diseases such as retinitis pigmentosa and age-related macular degeneration. While there are currently no available treatments to reverse this degeneration, a newly developed compound allows other cells in the eye to act like photoreceptors. As described in a study appearing in the February 19 issue of the Cell Press journal Neuron, the compound may be a potential drug candidate for treating patients...

Breakthrough allows Einstein scientists to probe how memories form in nerve cells In two studies in the January 24 issue of Science, researchers at Albert Einstein College of Medicine of Yeshiva University used advanced imaging techniques to provide a window into how the brain makes memories. These insights into the molecular basis of memory were made possible by a technological tour de force never before achieved in animals: a mouse model developed at Einstein in which molecules crucial...

Inflammatory demyelinating pseudotumor usually occurs in the brain and rarely occurs in the spinal cord. On imaging, inflammatory demyelinating pseudotumor appears very similar to intramedullary tumors such as gliomas. It is often misdiagnosed as intramedullary tumor and surgically resected. In view of this, the clinical and magnetic resonance imaging manifestations and the pathological features of 36 cases of inflammatory demyelinating pseudotumor in the spinal cord were retrospectively...
