Warning from new SLU research: Usual test for vitamin deficiency can mislead doctors

A test that generally is used to measure the amount of vitamin B12 in the body is not sensitive enough to detect a deficiency of the vitamin, which has been linked to several neurological conditions, according to Saint Louis University research. The findings were presented this month at a meeting of the American Neurological Association.

“B12 deficiency is associated with dementia, peripheral neuropathy and spinal cord disease,” says Florian Thomas, M.D., Ph.D., associate profess

Is the zebra fish leading us to new therapies?

A little over a year ago, the Flanders Interuniversity Institute for Biotechnology (VIB), the D. Collen Research Foundation, and the Catholic University of Leuven invested in the acquisition of a new technology provided by the zebra fish. This small aquarium fish can be used to aid the study of the function of human genes. That this investment is reaping returns is evident from the study that VIB researchers at the Catholic University of Leuven are publishing today in the renowned journal Nature.

AAN, ANA announce support for embryonic and adult human stem cell research

American Academy of Neurology and the American Neurological Association, together representing more than 18,000 neurologists and neuroscience professionals, today announced their support for government funding of adult and embryonic stem cell research.

The “The AAN and ANA recognize there are differing ethical opinions on the status of embryos that cannot be resolved to the satisfaction of all through medical science alone,” according to American Academy of Neurology president Sand

Growing epidemic of wet AMD ushers in new era in treatment of the disease

Retina specialists and ophthalmologists are encouraged by promising new scientific approaches that could have the potential to reduce the devastating effects of wet AMD for patients and offer the medical community a new paradigm of care, according to presentations made at the 2004 Annual Meeting of the American Academy of Ophthalmology in New Orleans.

Many experts consider AMD, the leading cause of blindness in Americans over age 50, as a growing public health epidemic. Diagno

Nerve Navigation Findings Prompt New Direction for Spinal Cord Research

A piece of the puzzle of how nerves find their way across the midline of the brain and spinal cord in a developing embryo has been found by Medical College of Georgia researchers.

They have found that an enzyme called focal adhesion kinase tells the arm-like extension of a neuron to cross the midline of the spinal cord, says Dr. Wen-Cheng Xiong, developmental neurobiologist and lead author on the paper in the November issue of Nature Neuroscience. After crossing, the axon become

Gene for common form of Parkinson’s pinpointed

Researchers have identified a new gene that causes a common form of inherited Parkinson’s disease (PD) and whose understanding they believe “will impact not only patients and their families but will open novel avenues of research aimed at identifying and ultimately halting the molecular events that lead to PD.”

The international research team reported finding the gene in a mutant form in five families from Spain and the United Kingdom. They have named the protein “dard
