UAlberta medical researchers discover how immune system kills healthy cells

Medical scientists at the University of Alberta have made a key discovery about how the immune system kills healthy cells while attacking infections. This finding could one day lead to better solutions for cancer and anti-viral treatments.

Faculty of Medicine & Dentistry researcher Colin Anderson recently published his team's findings in the peer-reviewed journal, Journal of Immunology. His team included colleagues from the United States and the Netherlands, and graduate students from the U of A.

ASU scientists strike scientific gold with meteorite

An important discovery has been made concerning the possible inventory of molecules available to the early Earth. Scientists led by Sandra Pizzarello, a research professor at Arizona State University, found that the Sutter's Mill meteorite, which exploded in a blazing fireball over California last year, contains organic molecules not previously found in any meteorites. These findings suggest a far greater availability of extraterrestrial organic molecules than previously thought possible, an inventory that could indeed have been important in molecular evolution and life itself.

NCI scientists identify targets for melanoma immunotherapy

PHILADELPHIA — Using a highly sensitive technology called NanoString, researchers have identified seven targets that could potentially be used to develop new immunotherapies for patients with metastatic melanoma, according to a study published in Clinical Cancer Research, a journal of the American Association for Cancer Research.

5-fold increase in ADHD medication use in children and adolescents

New Rochelle, NY, September 10, 2013—Use of stimulant medications to treat Attention-Deficit/Hyperactivity Disorder (ADHD) in children and adolescents has increased significantly over the past several years.

Study details paired risk factors in preeclampsia

PROVIDENCE, R.I. [Brown University] — Although preeclampsia occurs in about 3 percent of pregnancies, it's still unforeseen in many cases. A report of new research, now in press at the Journal of Reproductive Immunology, documents how two distinct risk factors combine to affect the odds that a first-time mother could develop the sometimes life-threatening pregnancy complication. The findings suggest there could be new ways to plan pregnancy with improved awareness and management of the risk.

US faces crisis in cancer care, says new IOM report

WASHINGTON -- Delivery of cancer care in the U.S. is facing a crisis stemming from a combination of factors -- a growing demand for such care, a shrinking oncology work force, rising costs of cancer care, and the complexity of the disease and its treatment, says a new report from the Institute of Medicine. The report recommends ways to respond to these challenges and improve cancer care delivery, including by strengthening clinicians' core competencies in caring for patients with cancer, shifting to team-based models of care, and communicating more effectively with patients.

Study: Redefining the criteria for ALK positive lung cancer

A University of Colorado Cancer Center study published today in the journal Cancer shows that the current criteria used to match lung cancers with the drug crizotinib may miss some patients who could benefit from the drug. The findings suggest that doctors should look closer at borderline or atypical ALK-negative cases, and could widen the population of lung cancer patients offered treatment with crizotinib or other ALK-inhibitor drugs.

African-American study identifies 4 genetic variants associated with blood pressure

Case Western Reserve University is part of a landmark study that has discovered four novel gene variations which are associated with blood pressure. The 19-site meta-analysis, involving nearly 30,000 African-Americans, also found that the set of genetic mutations are also associated with blood pressure across other populations.

Statins being overprescribed for growing number of kidney disease patients

PORTLAND, Ore. – A new analysis concludes that large numbers of patients in advanced stages of kidney disease are inappropriately being prescribed statins to lower their cholesterol – drugs that offer them no benefit and may increase other health risks such as diabetes, dementia or muscle pain.

The findings, which were published in the American Journal of Cardiovascular Drugs as a review of multiple studies, raise serious questions about the value of cholesterol-lowering therapies in kidney disease.

Changing part of central line could reduce hospital infections

AUGUSTA, Ga. – Simply replacing the connector in the IV system in patients with central lines could help reduce deadly bloodstream infections, researchers at Georgia Regents University have found.

A central line or central catheter is a tube placed in a patient's arm or chest to help deliver fluids, blood, or medications through the large veins near the heart. A connector sits at the top of the catheter and serves as the entry point for the fluid pathway inside – any fluid that goes in or comes out of the body, goes through the connector.

Why does a fancy purse say 'stay away from my man'?

Women are unconsciously deterring romantic rivals by buying certain luxury items, according to a new study in the Journal of Consumer Research.

"Spending on luxury goods in the US amounts to as much as $525 billion per year, with women's products accounting for over half of this consumption. Why do women desire luxury goods?" write authors Yajin Wang and Vladas Griskevicius (both University of Minnesota).

The price of envy: How do consumers react to flattering salespeople?

Consumers have negative reactions to flattery by salespeople, even if they think the compliments are sincere, according to a new study in the Journal of Consumer Research. But disliking a salesperson doesn't mean a customer won't buy from the store.

Why are consumers more likely to participate in online gaming than gambling?

Consumers are more likely to participate in online betting if it's called "gaming" rather than "gambling," according to a new study in the Journal of Consumer Research.

Does entering the lottery affect consumers' self-control?

A simple action like buying a lottery ticket can trigger materialistic thoughts, which cause consumers to lose self-control, according to a new study in the Journal of Consumer Research.

"Materialism, a set of beliefs about the importance of possessions in a consumer's life, is associated with a host of negative outcomes," writes author Hyeongmin (Christian) Kim (Johns Hopkins University). "Some examples include impulsive buying and excessive debt, both of which can be viewed as manifestations of poor self-control."

Wordplay persuades for customer reviews of truffles, but not laundry detergent

Ads or consumer reviews that use metaphors and wordplay can be effective, but it depends on the product, according to a new study in the Journal of Consumer Research.
