MGH research suggests strategies for improving drug delivery to cancer cells

The best cancer drugs in the world are not much good if they cannot get to tumor cells. That problem has been challenging cancer physicians and researchers for years because the physical structure of many tumors can prevent anticancer agents from reaching their targets. In a study appearing in the June issue of Nature Medicine, researchers from Massachusetts General Hospital (MGH) describe a new technique for

Low-tech ‘Main Squeeze’ compresses for snug fit inside vehicle

Three Johns Hopkins University undergraduates have invented a low-tech tool that makes it much easier to properly install child safety seats in automobiles, ensuring a snug fit and maximum protection for the child.

The device, dubbed “Main Squeeze,” is intended to simplify the difficult task of compressing a child safety seat against a car’s permanent seat during installation. Incorrectly installed, a loose

The production of lariat RNAs is a key step in the biologically important process of splicing. Because splicing changes the protein that is made from a given gene, a fundamental understanding of splicing is critical for comprehending the connections between genes and proteins. The study of splicing, however, has been very difficult in part because lariat RNAs have been nearly impossible to make artificially.

Now, chemistry professor Scott K. Silverman and graduate student Yangming Wang at th

A bacteria-killing virus found in the feces of some sheep could help remove the dangerous foodborne bacteria Escherichia coli O157:H7 from livestock. Researchers from Evergreen State College in Olympia, Washington present their research today at the 103rd General Meeting of the American Society for Microbiology.

“Here we report a promising new natural way of reducing pathogen concentrations in livestock. This takes advantage of bacteriophages – bacteria-killing viruses, harmless to humans a

A new anti-herpes agent derived from a common herb effectively treats and prevents the disease in animals. Researchers from Dalhousie University in Nova Scotia present their data today at the 103rd General Meeting of the American Society for Microbiology.

“Prunella vulgaris [also known as self-heal] is a perennial plant commonly found in China, the British Isles, Europe, and North America. In herbal literature, P. vulgaris has been described as a hot water infusion to treat sores in the mou

The link between environmental tobacco smoke and coronary heart disease and lung cancer may be considerably weaker than generally believed, conclude James Enstrom of the University of California, Los Angeles and Geoffrey Kabat of New Rochelle, New York, in this week’s BMJ.

This study will add to the already controversial debate on the health impact of passive smoking.

Their analysis involved 118,094 California adults enrolled in the American Cancer Society cancer prevention study in
