Study links chemicals widely found in plastics and processed food to elevated blood pressure in children and teens

Plastic additives known as phthalates (pronounced THAL-ates) are odorless, colorless and just about everywhere: They turn up in flooring, plastic cups, beach balls, plastic wrap, intravenous tubing and—according to the Centers for Disease Control and Prevention—the bodies of most Americans. Once perceived as harmless, phthalates have come under increasing scrutiny. A growin

Changing cancer's environment to halt its spread

By studying the roles two proteins, thrombospondin-1 and prosaposin, play in discouraging cancer metastasis, a trans-Atlantic research team has identified a five-amino acid fragment of prosaposin that significantly reduces metastatic spread in mouse models of prostate, breast and lung cancer. The findings suggest that a prosaposin-based drug could potentially block metastasis in a va

Estimates reveal low population immunity to new bird flu virus H7N9 in humans

The level of immunity to the recently circulating H7N9 influenza virus in an urban and rural population in Vietnam is very low, according to the first population level study to examine human immunity to the virus, which was previously only found in birds. The findings have implications for planning the public health response to this pandemic threat.

Novel RNA-based classification system for colorectal cancer

A novel transcriptome-based classification of colon cancer that improves the current disease stratification based on clinicopathological variables and common DNA markers is presented in a study published in PLOS Medicine this week. (A transcriptome is all RNA produced by a population of cells.) Pr. Pierre Laurent-Puig and colleagues from INSERM in Paris, France used genetic information from

Protein study suggests drug side effects are inevitable

A new study of both computer-created and natural proteins suggests that the number of unique pockets – sites where small molecule pharmaceutical compounds can bind to proteins – is surprisingly small, meaning drug side effects may be impossible to avoid. The study also found that the fundamental biochemical processes needed for life could have been enabled by the simple physics of protein folding.

Older prostate cancer patients should think twice before undergoing treatment

Older prostate cancer patients with other underlying health conditions should think twice before committing to surgery or radiation therapy for their cancer, according to a multicenter study led by researchers in the UCLA Department of Urology.

Team finds mechanism linking key inflammatory marker to cancer

In a new study described in the journal Oncogene, researchers reveal how a key player in cell growth, immunity and the inflammatory response can be transformed into a primary contributor to tumor growth.

Genetic diversity within tumors predicts outcome in head and neck cancer

A new measure of the heterogeneity – the variety of genetic mutations – of cells within a tumor appears to predict treatment outcomes of patients with the most common type of head and neck cancer. In the May 20 issue of the journal Cancer, investigators at Massachusetts General Hospital (MGH) and Massachusetts Eye and Ear Infirmary describe how their measure was a better predictor of survi

High-testosterone competitors more likely to choose red

Why do so many sports players and athletes choose to wear the color red when they compete? A new study to be published in Psychological Science, a journal of the Association for Psychological Science, suggests that it may have to do with their testosterone levels.
