Alzheimer's gene slows brain's ability to export toxic protein

The only known genetic risk factor for Alzheimer's disease slows down the brain's ability to export a toxic protein known as amyloid-beta that is central to the damage the disease causes, scientists have found.

Hope for treating relapse to methamphetamine abuse

"Reinstatement of drug-seeking behavior after an extended period of abstinence is the number-one cause of drug-addiction relapse," said Brookhaven neuroanatomist Stephen Dewey, who led the research team. "This animal study suggests that vigabatrin could potentially prevent human methamphetamine addicts from relapsing."

Breakthrough in cell-type analysis offers new ways to study development and disease

Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.

Widespread public support for large genetic study

Four in five Americans support the idea of a nationwide study to investigate the interactions of genes, environment and lifestyle, and three in five say they would be willing to take part in such a study, according to a survey released today.

Discovery of stem cells with potential to regenerate injured liver tissue

A novel protein marker has been found that identifies rare adult liver stem cells, whose ability to regenerate injured liver tissue has the potential for cell-replacement therapy.

Sex differences narrow in death after heart attack

In recent years, women, particularly younger women, experienced larger improvements in hospital mortality after myocardial infarction than men, according to a new study.

Research shows why some heart failure treatments fail

Do the biological underpinnings of heart failure share more in common with cancerous tumors than other cardiovascular diseases?

Blood levels of resistin a new biomarker for heart failure

Blood levels of resistin, a hormone produced by fat cells, can independently predict an individual's risk of heart failure, cardiologists at Emory University School of Medicine have found.

Messages of hope work better in motivating black patients to seek early screening for cancer

News articles that stress African-American health disparities, like higher cancer mortality rates than other groups, may discourage black patients from being screened for cancer, according to a Saint Louis University study.

Discovery of essential mechanism for maintenance of myelin's structure

In a new study, researchers at the Montreal Neurological Institute (MNI), McGill University, and the University of Montreal have discovered an essential mechanism for the maintenance of the normal structure of myelin, the protective covering that insulates and supports nerve cells (neurons).

Adults with severe heart failure have more doctor visits, medications than others on Medicare

Adults with severe heart failure see almost three times as many Medicare providers each year compared to a typical beneficiary, according to research presented at the American Heart Association's Scientific Sessions 2008.

Discovery of unique approach for delivering drugs to the brain - potential for Alzheimer's and stroke

Saint Louis University researchers have identified a novel way of getting a potential treatment for Alzheimer's disease and stroke into the brain where it can do its work.

Regularly exercise good for heart failure patients

Heart failure patients who regularly exercise fare better and feel better about their lives than do similar patients who do not work out on a regular basis, say researchers at Duke University Medical Center.

Dual treatment for stroke leads to improved recovery rates, reduced mortality

It appears that stroke patients who receive both intravenous thrombolysis - a minimally invasive treatment that dissolves abnormal blood clots - and endovascular interventions - such as drugs and implanting medical devices - are much more likely to recover and have lower chances of dying, according to new research by the Zeenat Qureshi Stroke Research Center at the University of Minnesota Medical School.
