Protein regulates movement of mitochondria in brain cells

Scientists have identified a protein in the brain that plays a key role in the function of mitochondria - the part of the cell that supplies energy, supports cellular activity, and potentially wards off threats from disease.The discovery, which was reported today in the Journal of Cell Biology, may shed new light on how the brain recovers from stroke.

Novel approach for treating cognitive impairments

Researchers have been seeking a safe and effective way to treat cognitive impairments associated with schizophrenia by enhancing N-methyl-D-aspartate (NMDA) glutamate receptors. Functional deficits in NMDA receptors may contribute to the underlying neurobiology of this disorder.

Research links primary insomnia to specific neurochemical abnormality

A research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, is the first demonstration of a specific neurochemical abnormality in adults with primary insomnia (PI), providing greater insight to the limited understanding of the condition's pathology.

Eyes provide clues to a common cause of stroke

In a groundbreaking study researchers have concluded that evidence of the cause of "lacunar stroke" can be found by looking at the back of a patient's eyes.

Discovery of new arenavirus associated with hemorrhagic fever – first identified in nearly four decades

Scientists at Columbia University's Mailman School of Public Health, the South African National Institute for Communicable Diseases of National Health Laboratory Service (NICD-NHLS), the U.S. Centers for Disease Control and Prevention, and Roche's 454 Life Sciences Corporation have discovered the new virus responsible for a highly fatal hemorrhagic fever outbreak in Zambia and South Africa in late 2008.

Discovery of gene that regulates tumors in neuroblastoma

Virginia Commonwealth University researchers have identified a gene that may play a key role in regulating tumor progression in neuroblastoma, a form of cancer usually found in young children. Scientists hope the finding could lead to an effective therapy to inhibit the expression of this gene.

Findings in epilepsy gene in animals may guide treatment directions for infants

Researchers studying a difficult-to-treat form of childhood epilepsy called infantile spasms have developed a line of mice that experiences seizures with features closely resembling those occurring in patients with infantile seizures. These genetically engineered mice provide a new opportunity for scientists to test treatments that may benefit children.

Statins may help prevent stroke recurrence

People who take cholesterol-lowering drugs called statins after a stroke may be less likely to have another stroke later, according to research published in the May 26, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Transition to menopause may cause trouble learning

The largest study of its kind to date shows that women may not be able to learn as well shortly before menopause compared to other stages in life. The research is published in the May 26, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Prevalence of vCJD agent in Britain remains uncertain

First results from a large tissue survey in Britain of the agent that causes variant Creutzfeldt-Jakob disease (vCJD) are unable so far to establish that the prevalence is lower than that given by previous estimates, concludes a study published on bmj.com.

Discovery of neurons that 'mirror' the attention of others

Whether a monkey is looking to the left or merely watching another monkey looking that way, the same neurons in his brain are firing, according to researchers at the Duke University Medical Center.

Weight loss in seniors may increase risk of dementia

A new study shows that older people who are thinner or are losing weight quickly are at a higher risk of developing dementia, especially if they started out overweight or obese. The research is published in the May 19, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

New hope for warding off diabetes nerve loss

A common blood test for triglycerides - a well-known cardiovascular disease risk factor - may also for the first time allow doctors to predict which patients with diabetes are more likely to develop the serious, common complication of neuropathy.

Discovery of pathway that reactivate myelin repair

UMDNJ researchers have identified a key pathway that could lead to new therapies to repair nerve cells' protective coating stripped away as a result of autoimmune diseases such as Multiple Sclerosis (MS). An article reporting their findings will appear in the May 13 online edition of the Journal of Neuroscience.
