Research offers promise for people with learning disabilities

Learning disabilities such as dyslexia are believed to affect nearly one in 10 children. To better study them, a Northwestern University research team has developed a data-driven conceptual framework that links two well-established scientific concepts. In doing so, they also have developed a non-invasive diagnostic tool called BioMAP that can quickly identify children with learning disabilities.

Bionic eyes from Stanford

Stanford physicists and eye doctors have teamed up to design a "bionic eye," of sorts. On Feb. 22 in the Journal of Neural Engineering, Daniel Palanker, Alexander Vankov and Phil Huie from the Department of Ophthalmology and the Hansen Experimental Physics Laboratory and Stephen Baccus from the Department of Neurobiology published a design of an optoelectronic retinal prosthesis system that can stimulate the retina with resolution corresponding to a visual acuity of 20/80

Chronic pain treatments more effective when taken together

People suffering from chronic, debilitating pain caused by nerve damage or disease report better pain relief at lower doses of a combined drug treatment than from either drug administered individually, a new Queen’s study funded by the Canadian Institutes of Health Research (CIHR) shows.

Patch therapy provides similar pain relief as oral medications for patients with osteoarthritis (OA) knee pain

Researchers from the Altoona Arthritis and Osteoporosis Center have announced that data presented at the 24th Annual Scientific Meeting of the American Pain Society suggest that patch therapy provides similar pain relief as oral medications for patients with osteoarthritis (OA) knee pain.

Hair follicle stem cells may provide an accessible source of stem cells for therapeutic applications

Hair grows quickly and is continually replenished which makes it an attractive source to harvest the amount of stem cells needed for treatments, but this, along with controversy surrounding the ethics of harvesting cells from embryos, has been a major stumbling block of stem cell research.

Adult stem cells could be used to treat deaf patients in the future

Researchers at Indiana University School of Medicine are several steps closer to the day when a profoundly deaf patient's own bone marrow cells could be used to let him or her hear the world.

Invisible influences reveal unconscious pathways used in visual perception

Our conscious awareness is underpinned by activity in our brain, but there is far more going on in our brain at any one time than we can possibly be aware of. So what aspects of our brain's activity are we actually aware of?

Researchers have identified the proteins that allow specific brain cells to "change channels"

Johns Hopkins researchers have identified the proteins that allow specific brain cells to "change channels," a rare ability that tweaks what can come into the cell. The findings, described in the March 24 issue of Neuron, might let researchers harness the process, perhaps one day using it to protect cells that die in Lou Gehrig's disease.

Ultrafast laser detection of cancer cells also may improve understanding of stem cells

To investigate tumors, pathologists currently rely on labor-intensive microscopic examination, using century-old cell-staining methods that can take days to complete and may give false readings.

Federal database used to track trends in cochlear implant complications

Changes in the format of a federal database for mandatory reporting of major and minor complications for medical devices, including cochlear implants, could make it a valuable resource, according to an article in the March issue of Archives of Otolaryngology – Head & Neck Surgery.

MicroJet injector for painless injections

Parents know all too well the pain experienced by their children - and themselves - when the time comes for immunizations at the doctor's office.

RNA loops and knots guide genetic modifications

University of Connecticut Health Center scientist, Robert Reenan, has uncovered new rules of RNA recoding - a genetic editing method cells use to expand the number of proteins assembled from a single DNA code.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.

Study finds spikes in blood pressure, heart rate, adrenaline after 'dipping' snuff

After snuff use, heart rate increased by about 15 beats per minute (25 percent), systolic blood pressure went up by 12 mmHg (10 percent), and measurements of adrenalin in the bloodstream increased by more than 50 percent.

Gene therapy helps Lou Gehrig's disease

The most common form of motor neurone disease, called amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease, is caused when neurones in the spinal cord die, leading to muscle wasting and total paralysis.

Functional magnetic resonance imaging shows that hypnosis eases pain

Although hypnosis has been shown to reduce pain perception, it is not clear how the technique works. Identifying a sound, scientific explanation for hypnosis' effect might increase acceptance and use of this safe pain-reduction option in clinical settings.

High-dose radiation and bone marrow transfer treatments on glaucoma-susceptible mice completely blocked development of glaucoma

In a discovery that could point to new treatments for a wide range of neurodegenerative diseases, Jackson Laboratory researchers have found that high-dose radiation and bone marrow transfer treatments on glaucoma-susceptible mice completely blocked the development of glaucoma, by preventing neurodegeneration.

Active brains stave off Alzheimer's signs

Mice who keep busy playing with toys also keep their brains and bodies active; more importantly, they also have lower levels of the peptides and brain plaques associated with Alzheimer's disease, compared to mice raised in environments not "enriched" with chew toys, running wheels,and tunnels, according to a new study in the 11 March issue of the journal Cell.

Commonly used anesthetic regimen appears to have no negative effects on the developing brain of the fetus

An anesthetic regimen commonly used during surgery on pregnant mothers appears to have no negative effects on the developing brain of the fetus, according to a new study on sheep conducted by Duke University Medical Center researchers.

Common anesthetics appear safe for developing fetal brain

A group of Dartmouth researchers has learned that the brain's auditory cortex, the part that handles information from your ears, holds on to musical memories.
