Checkpoint inhibitor-based immunotherapy has been shown to be very effective in recurrent and metastatic head and neck cancer but only in a minority of patients. University of California San Diego School of Medicine researchers may have found a way to double down on immunotherapy’s effectiveness.

By delivering strands of genetic material known as messenger RNA (mRNA) into cells, researchers can induce the cells to produce any protein encoded by the mRNA. This technique holds great potential for administering vaccines or treating diseases such as cancer, but achieving efficient delivery of mRNA has proven challenging.

First, the good news. Washington State University researchers have found that a rat exposed to a popular herbicide while in the womb developed no diseases and showed no apparent health effects aside from lower weight.

Victims of gunshots and stabbings are significantly less likely to die if they’re taken to the trauma center by a private vehicle than ground emergency medical services (EMS), according to results of a new analysis.

Opening up a new pathway to fight cancer, researchers at the University of Pennsylvania have found a way to target an enzyme that is crucial to tumor growth while also blocking the mechanism that has made past attempts to target that enzyme resistant to treatment. Researchers were able to use this finding to develop a drug that successfully inhibits tumor growth of melanoma as well as pancreatic and colorectal cancer in mice. The journal Cancer Discovery published the findings online this month.

People who handle paper receipts regularly may be at increased risk for exposure to a chemical linked to breast and prostate cancers, according to new UAlberta research.

“We found that people who handled receipts printed on thermal paper containing the chemical had it lingering in their body for a week or more,” said Jiaying Liu, a PhD candidate in UAlberta’s Department of Laboratory Medicine and Pathology.

Teenagers who try e-cigarettes double their risk for smoking tobacco cigarettes, according to a new study.

The study — from the University of Waterloo and the Wake Forest School of Medicine — found that students in grades seven to 12 who had tried an e-cigarette are 2.16 times more likely to be susceptible to cigarette smoking.

Workers who were likely exposed to dispersants while cleaning up the 2010 Deepwater Horizon oil spill experienced a range of health symptoms including cough and wheeze, and skin and eye irritation, according to scientists at the National Institutes of Health (NIH). The study appeared online Sept. 15 in Environmental Health Perspectives and is the first research to examine dispersant-related health symptoms in humans.

Children exposed to high indoor levels of pet or pest allergens during infancy have a lower risk of developing asthma by 7 years of age, new research supported by the National Institutes of Health reveals. The findings, published September 19 in the Journal of Allergy and Clinical Immunology, may provide clues for the design of strategies to prevent asthma from developing.

Scientists have uncovered two related cytokines and associated genetic markers that may explain why some people develop progressive multiple sclerosis, or MS. The study, led by researchers at OHSU in Portland, Oregon, and Yale University, point the way toward developing the first-ever treatment to prevent progressive forms of the disease.
