Researchers have shown how an experimental drug might restore the function of nerves damaged in spinal cord injuries by preventing short circuits caused when tiny "potassium channels" in the fibers are exposed. The chemical compound also might be developed as a treatment for multiple sclerosis. Because nerves usually are not severed in a common type of spinal cord trauma, called "compression" injuries, the drug offers hope as a possible treatment, said Riyi Shi, a professor in Purdue...

Researchers at Karolinska Institutet have discovered a mechanism that controls the brain's ability to create lasting memories. In experiments on genetically manipulated mice, they were able to switch on and off the animals' ability to form lasting memories by adding a substance to their drinking water. The findings, which are published in the scientific journal PNAS, are of potential significance to the future treatment of Alzheimer's and stroke. "We are constantly being swamped with sensory...

Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident. The synthetic "copolymer micelles" are drug-delivery spheres about 60 nanometers in diameter, or roughly 100 times smaller than the diameter of a red blood cell. Researchers have been studying how to deliver drugs for cancer treatment and other therapies using these spheres. Medications...

Enzyme could lead to a possible treatment for brain and spinal cord injury Researchers at Children's Hospital Boston report that an enzyme known as Mst3b, previously identified in their lab, is essential for regenerating damaged axons (nerve fibers) in a live animal model, in both the peripheral and central nervous systems. Their findings, published online by Nature Neuroscience on October 25, suggest Mst3b "“ or agents that stimulate it "“ as a possible means of treating stroke,...

Animal studies at University of Michigan also show potential to restore sense of touch Modern tissue engineering developed at the University of Michigan could improve the function of prosthetic hands and possibly restore the sense of touch for injured patients. Researchers will present their updated findings Wednesday at the 95th annual Clinical Congress of the American College of Surgeons. The research project, which was funded by the Department of Department of Defense, arose from a need...

Scientists create nerve cell connections in vitro using artificial substances, a major advance towards nerve cell repair The repair of damaged nerve cells is a major problem in medicine today. A new study by researchers at the Montreal Neurological Institute and Hospital (The Neuro) and McGill University, is a significant advance towards a solution for neuronal repair. The study featured on the cover of the October 7 issue of Journal of Neuroscience, is the first to show that nerve cells will...

A U.S. researcher suggests his myelin model -- based on a sheat the covers nerve axons -- is cause for rethinking Alzheimer's disease. George Bartzokis of the University of California, Los Angeles, says present drug targets -- the amyloid-beta peptide and the tau peptide implicated in Alzheimer's as well as clinical signs such as memory loss -- are actually preceded by the breakdown of myelin. Bartzokis explains myelin -- the fatty sheath covering the nerve axons, allowing for efficient...

Canadian scientists say they've found the interaction of a specific protein regulates the development of nerve connections in the visual system of tadpoles. The researchers at the Montreal Neurological Institute and Hospital said their findings help clarify how networks of nerve cell connections become established in human brains. The scientists focused on the interactions between a schizophrenia-linked gene product, Calcineurin, and a transcription factor known to contribute to the...

In the July issue of Biomaterials, published by Elsevier, researchers from the University of Central Florida (UCF) report on the first lab-grown motor nerves that are insulated and organized just like they are in the human body. The model system will drastically improve understanding of the causes of myelin-related conditions, such as diabetic neuropathy and later, possibly multiple sclerosis (MS). In addition, the model system will enable the discovery and testing of new drug therapies for...

Multiple sclerosis, diabetic neuropathy, and other conditions caused by a loss of myelin insulation around nerves can be debilitating and even deadly, but adequate treatments do not yet exist. That's in large part because of deficiencies in model research systems. In an upcoming issue of the journal Biomaterials, a UCF team addresses this problem with a report on the first lab-grown motor nerves that are insulated and organized the same way they are in the body. The group's model system,...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
