Gleevec holds potential as first drug to successfully treat neurofibromatosis

Researchers at the Indiana University School of Medicine report that the anti-cancer drug Gleevec holds out promise to become the first effective treatment for neurofibromatosis, a genetic disease that has resisted treatments until now.

Pulsed ultrasound used to remote control brain circuits

In a twist on nontraditional uses of ultrasound, a group of neuroscientists at Arizona State University has developed pulsed ultrasound techniques that can remotely stimulate brain circuit activity.

Scientists discover a catalytic antibody that degrades a known appetite stimulant

The antibody works against the gastric hormone ghrelin (pronounced "grell-in"), which has been linked to weight gain and fat storage through its metabolic actions. These findings point towards a potentially novel treatment for obesity that would interfere directly with the some of the biological mechanisms determining weight.

Anxiety disorders latest worry in high blood pressure

Family doctors and psychiatrists should carefully monitor the heart health of patients with anxiety disorders, Dr. Simon Bacon told the Canadian Cardiovascular Congress 2008, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society. "People with anxiety disorders are four times more likely to develop high blood pressure (hypertension) over one year than those of us who are anxiety free," says Dr. Bacon, a Heart and Stroke Foundation researcher at the Montreal Heart Institute. "Hypertension is a leading risk factor for stroke and heart disease."

In mice, anxiety is linked to immune system

In the first study ever to genetically link the immune system to normal behavior, scientists at Rockefeller and Columbia universities show that mast cells, known as the pharmacologic bombshells of the immune system, directly influence how mice respond to stressful situations.

Memory Pharmaceuticals issued key U.S. patent for series of nicotinic alpha-7 receptor agonists

Memory Pharmaceuticals Corp. has announced the issuance of U.S. Patent No. 7,429,664, which provides composition of matter patent protection for a series of nicotinic alpha-7 receptor agonists.

Exposure to low doses of mercury changes the way the arteries work

An international team of researchers has shown that mercury is another important factor in cardiovascular disease as it changes the way arteries work. One of the possible sources of exposure of humans to mercury is by eating contaminated fish.

Gene mutation in worms could further understanding of alcoholism in humans

The work follows a study carried out by Oregon Health and Science University, which suggested a link between a gene mutation in mice and tolerance to alcohol. Researchers at Liverpool have investigated this in worms, looking specifically at the role the gene plays in communication between cells in the nervous system.

Gene study sheds new light on lung cancer

A multi-institution team, funded by the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH), today reported results of the largest effort to date to chart the genetic changes involved in the most common form of lung cancer, lung adenocarcinoma. The findings should help pave the way for more individualized approaches for detecting and treating the nation's leading cause of cancer deaths.

Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

Cell phones and brain cancer - major research initiatives needed

Major research initiatives are needed immediately to assess the possibility that using cellular phones may lead to an increased risk of brain tumors, according to an editorial in the November issue of the journal Surgical Neurology, published by Elsevier.

Targeted cell delivery to the cervical spinal cord is a promising strategy to slow loss of motor neurons in ALS

In a disease like ALS - one that's always fatal and that has a long history of research-resistant biology - finding a proof of principle in animal models is significant.

Beyond recognizing odors, a single neuron controls reactions

Babies will smile when they catch the scent of vanilla, but a whiff of rotting meat will send them into fits. From people to mice and flies to worms, animals of all kinds are born with likes and dislikes thanks to the evolutionary wisdom collected in their genes. But new research shows that some preferences are still surprisingly flexible at even the most basic level - that of the sensory neuron itself - and that our nervous system may be even more adaptable than we thought.

Chronic disease keeping older Australians out of the workforce

Chronic diseases such as diabetes and arthritis may be keeping more than 660,000 older Australians out of the workforce, Sydney University academics have found.

FDA approves new labeling for psoriasis drug Raptiva

The U.S. Food and Drug Administration today announced labeling changes, including a Boxed Warning, to highlight the risks of life-threatening infections, including progressive multifocal leukoencephalopathy (PML), with the use of Raptiva (efalizumab). The labeling changes are based on the FDA's post-market surveillance.

NIH funds two new centers for imaging technology for neurodegenerative disorders and software for protein analysis

The National Center for Research Resources (NCRR), a part of the National Institutes of Health (NIH), announced today it will provide up to an estimated $11 million over the next five years to create two new Biomedical Technology Research Centers (BTRCs) that will provide researchers nationwide with access to specialized research tools, training and state-of-the-art equipment.

Respiratory sinus arrhythmia is a significant predictor of insomnia in women with breast cancer

A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that respiratory sinus arrhythmia (RSA) is a significant predictor of insomnia in women with breast cancer and confirmed that longer nocturnal wake episodes were associated with a flatter diurnal cortisol slope.
