Stem cell therapy rescues motor neurons in ALS model

In a study that demonstrates the promise of cell-based therapies for diseases that have proved intractable to modern medicine, a team of scientists from the University of Wisconsin-Madison has shown it is possible to rescue the dying neurons characteristic of amyotrophic lateral sclerosis (ALS), a fatal neuromuscular disorder also known as Lou Gehrig's disease.

CT-guided radiofrequency ablation effective in eradicating small malignant kidney tumors

A relatively new, minimally invasive treatment was 100 percent successful in eradicating small malignant kidney tumors in a study of more than 100 patients, report researchers from Wake Forest University Baptist Medical Center.

Discovery of molecular pathway that detects and eliminates defective messenger RNAs from red blood cells

Other such pathways - known as surveillance pathways - operate in a more general way, in many cell types. Knowing how this specific surveillance system works can help researchers better understand hereditary diseases, in this case, thalassemia, a form of anemia, which is the most common genetic disorder worldwide.

Music moves brain to pay attention

Using brain images of people listening to short symphonies by an obscure 18th-century composer, a research team from the Stanford University School of Medicine has gained valuable insight into how the brain sorts out the chaotic world around it.

Methylphenidate improves vigilance performance of ADHD children with poor sleep

WESTCHESTER, Ill. -- In the first known study of its kind, an article published in the August 1st issue of the journal SLEEP finds that children with attention deficit hyperactivity disorder (ADHD), and whose sleep efficiency is poor, experience significant improvement on some measures of the Continuous Performance Test (CPT) if they are treated with methylphenidate (MPH).

Screening method for pancreatic cancer in asymptomatic patients

EVANSTON, Ill. --- Optical technology developed by a Northwestern University biomedical engineer shown to be effective in the early detection of colon cancer now appears promising for detecting pancreatic cancer, the fourth most common cause of cancer deaths in the United States.
