New MS drug rituximab shows promise for multiple sclerosis

Genentech Inc. and Biogen Idec Inc.’s cancer drug Rituxan (rituximab) reduced brain lesions in multiple sclerosis patients. – A drug therapy, using rituximab, dramatically reduced the number of inflammatory lesions that form along nerve fibers in brains of multiple sclerosis patients, revealed by researchers recently.

DNA sequencing found virus killing transplant recipients in Australia

DNA sequencing establishes high throughput genetic sequencing as powerful tool for pathogen discovery; technology enables improvements in screening for transplant safety. – In the first application of high throughput DNA sequencing technology to investigate an infectious disease outbreak, link the discovery of a new arenavirus to the deaths of three transplant recipients who received organs from a single donor in Victoria, Australia in April 2007.

Parkinson’s disease risk reduced with high blood pressure drugs

People taking a widely used group of drugs known as calcium channel blockers to treat high blood pressure also appear to be cutting their risk of Parkinson’s disease, according to a study published in the February 6, 2008, online issue of Neurology, the medical journal of the American Academy of Neurology. – Parkinson’s disease risk is reduced in people taking drugs known as calcium channel blockers to treat high blood pressure, revealed by researchers in US.

Vitamin B12, folate deficiency raises dementia risk

Changes in folate, vitamin B12 and homocysteine associated with incident dementia. – Folate deficiency is associated with a tripling in the risk of developing dementia among elderly people, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry.

Epilepsy drugs may raise suicide risk, warns FDA

The U.S. Food and Drug Administration today issued new information to health care professionals to alert them about an increased risk of suicidal thoughts and behaviors (suicidality) in patients who take drugs called antiepileptics to treat epilepsy, bipolar disorder, migraine headaches, and other conditions. – An increased risk of suicidal thoughts and behaviors (suicidality) in patients who take drugs called antiepileptics to treat epilepsy, bipolar disorder, migraine headaches, and other conditions, reported by U.S. Food and Drug Administration (FDA).

Deep brain stimulation may improve memory

Hypothalamic deep brain stimulation (DBS) surgery may evoke detailed autobiographical memories. Deep brain stimulation (DBS) surgery, which is used to treat Parkinson?s disease and other movement disorders, is now being studied for its potential to treat a variety of conditions. – A new study found that hypothalamic deep brain stimulation (DBS) surgery performed in the treatment of a patient with morbid obesity unexpectedly evoked detailed autobiographical memories.

Stem cells may improve muscles in muscular dystrophy

Dr. Rita Perlingeiro’s research team has prompted the growth of healthy and functioning muscle cells in mice afflicted with a human model of Duchenne muscular dystrophy. This represents the first time transplanted embryonic stem cells have been shown to restore function to defective muscles in an MD model. – Using embryonic stem cells from mice, UT Southwestern Medical Center researchers have prompted the growth of healthy – and more importantly, functioning – muscle cells in mice afflicted with a human model of Duchenne muscular dystrophy. The study represents the first time transplanted embryonic stem cells have been shown to restore function to defective muscles in a model of muscular dystrophy.

Statins, cholesterol lowering drugs may not prevent Alzheimer’s Disease

A large US study suggests that statin, cholesterol lowering drug use does not lower the risk of Alzheimer’s disease (AD). – Taking statins, which are cholesterol-lowering drugs, offers no protection against Alzheimer’s disease, revealed by US researchers at Rush University Medical Center in Chicago.

Depressed girls can’t smell the roses

New Tel Aviv University (TAU) research links depression to loss of the sense of smell, suggesting that the blues may have biological roots. – Can’t smell the roses? Maybe you’re depressed. Smell too much like a rose yourself? Maybe you’ve got the same problem. Scientists from Tel Aviv University recently linked depression to a biological mechanism that affects the olfactory glands. It might explain why some women, without realizing it, wear too much perfume.

Novel anti-cancer strategy moves to clinic

Emory University researchers have developed a novel anti-tumor compound that represents a distinct strategy: targeting one of the most important “intercept points” for cancer cells. – Researchers at Emory University have developed a novel anti-tumor compound that represents a distinct strategy: targeting one of the most important “intercept points” for cancer cells.
