Researchers at the University of Illinois at Chicago report that increasing expression of a chemical cytokine called LIGHT in mice with colon cancer activated the immune system's natural cancer-killing T-cells and caused primary tumors and metastatic tumors in the liver to shrink.

Tens of millions of Americans with lung disease use metered-dose inhalers each day, and new studies by Rice University electrical engineers and pulmonologists at Baylor College of Medicine have identified critical errors that are causing many inhaler users to get only about half as much medicine as they should from each puff.

The scientists have found a molecule that stops the growth of an aggressive pediatric brain tumor. The tumor is always fatal and primarily strikes children under 10 years old. Every year, about 300 children under the age of 10 years old in the U.S. develop a tumor referred to as diffuse intrinsic pontine glioma (DIPG).

Donepezil, a medication that is approved to treat people with Alzheimer's disease, should not be prescribed for people with mild cognitive impairment without a genetic test. UCLA School of Nursing researchers discovered that for people who carry a specific genetic variation - the K-variant of butyrylcholinesterase, or BChE-K - donezpezil could accelerate cognitive decline.

A potentially life-saving treatment for sepsis has been under our noses for decades in the non-steroidal anti-inflammatory drugs (NSAIDs) most people have in their medicine cabinets, a new University of Colorado Boulder study suggests. Each year more than 1 million people in the United States contract sepsis, an overwhelming immune response to infection. It kills as many as half of those who contract it, sometimes within days, according to the National Institutes of Health.

A new study published in Brain indicates that successful treatment for insomnia may not actually require complicated neurofeedback (direct training of brain functions). Rather, it appears patients who simply believe they're getting neurofeedback training appear to get the same benefits.

The researchers from Imperial College London analysed 20 pharmacies that were available for UK citizens to access online. This is one of the few studies to have examined the online availability of antibiotics and to have explored the potential effects on public health. The research is published in Journal of Antimicrobial Chemotherapy.
