An experimental oral drug given to mice after a spinal cord injury was effective at improving limb movement after the injury, a new study shows. The compound efficiently crossed the blood-brain barrier, did not increase pain and showed no toxic effects to the animals. "This is a first to have a drug that can be taken orally to produce functional improvement with no toxicity in a rodent model," said Sung Ok Yoon, associate professor of molecular & cellular biochemistry at Ohio State...

San Francisco, CA, Dec. 15-19, 2012 Moscone Center, 747 Howard Street ORGANIZING THE EYE'S NEURONS Poster: 2342/B1205 Special Interest Subgroup: Tissue Development and Morphogenesis II Tuesday, Dec. 18, 2012; Exhibit Halls A-C, 12:30 — 2 p.m. Authors: A. R. Tomás and M. R. Deans Tomás and Deans have identified a protein needed for neuron organization in the developing retina. The team says that the study helps reveal how the healthy retina...

Promising Nerve Research From Stem Cells Plus Nanofibers

University of Michigan Health System Researchers coax cells to grow and myelinate along thin fibers, with potential use in testing treatments for neurological diseases Every week in his clinic at the University of Michigan, neurologist Joseph Corey, M.D., Ph.D., treats patients whose nerves are dying or shrinking due to disease or injury. He sees the pain, the loss of ability and the other effects that nerve-destroying conditions cause — and wishes he could give patients more...

Jedidiah Becker for redOrbit.com — Your Universe Online In 2005, Norwegian researchers discovered a previously unknown type of neuron by placing electrodes deep within the cerebral cortex of rats. Dubbed “grid cells,” these specialized neurons were so named because they fire in distinct clusters, each of which constitutes the vertex of a grid-like pattern of equilateral triangles. This recurring triangular, lattice-like firing pattern is what distinguishes grid cells from other...

A gene that is associated with regeneration of injured nerve cells has been identified by scientists at Penn State University and Duke University. The team, led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn State, has found that a mutation in a single gene can entirely shut down the process by which axons -- the parts of the nerve cell that are responsible for sending signals to other cells -- regrow themselves after being cut or damaged. "We are...

Monkeys Deconstruct The World Through Triangular Grids
2012-10-29 09:16:42

Brett Smith for redOrbit.com - Your Universe Online Researchers at Emory University have shown that some primates visually deconstruct the world through triangular grids. According to their report in the journal Nature, the scientists have identified grid cells in the brains of rhesus monkeys that fire in triangular patterns as their eyes scan a scene. Uncovering this brain activity in primates could have larger ramifications as the grid cells are connected to how we view and recall...

Researchers Find Easier Way To Perform Macular Degeneration Eye Test
2012-10-08 12:33:58

Lawrence LeBlond for redOrbit.com - Your Universe Online Age-related Macular Degeneration (AMD) is a condition that generally occurs in people over the age of 50, but also occurs in higher numbers of people who smoke, who are white, and people who have a family history of the often debilitating condition. And for those who had gone through AMD testing, they had generally had to sit in a darkened room for 20 minutes before testing had begun. But now, researchers from Australia´s...

Wayne State University School of Medicine researchers, working with colleagues in Canada, have found that one or more substances produced by a type of immune cell in people with multiple sclerosis (MS) may play a role in the disease's progression. The finding could lead to new targeted therapies for MS treatment. B cells, said Robert Lisak, M.D., professor of neurology at Wayne State and lead author of the study, are a subset of lymphocytes (a type of circulating white blood cell) that...

Korean scientists have used tiny stars, squares and triangles as a toolkit to create live neural circuits in a dish. They hope the shapes can be used to create a reproducible neural circuit model that could be used for learning and memory studies as well as drug screening applications; the shapes could also be integrated into the latest neural tissue scaffolds to aid the regeneration of neurons at injured sites in the body, such as the spinal cord. Published today, 20 July, in IOP...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
