Researchers identify the specific mechanism that triggers resistance to vancomycin A new study led by the scientific director of the Michael G. DeGroote Institute for Infectious Disease Research has uncovered for the first time how bacteria recognize and develop resistance to a powerful antibiotic used to treat superbug infections. Gerry Wright, a professor in the Department of Biochemistry and Biomedical Sciences at McMaster University in collaboration with colleagues at the John Innes...

Women are susceptible to HIV, the virus that causes AIDS, but scientists have been puzzled as to how it finds its way into the female reproductive tract. One theory has been that trauma, such as a little tear during intercourse, causes HIV to cross epithelial cells "“ the protective barrier that keeps out infection. There is also the suggestion an unknown mechanism is at work. For the first time, researchers at McMaster University have discovered the culprit could be HIV itself and what...

Hamilton, ON -- Aspirin, ibuprofen and other non-steroidal anti-inflammatory drugs (NSAIDs) remain the most common treatment to relieve symptoms of arthritis and other inflammatory disorders. But despite their widespread use (around 2.5 million Canadians have osteoarthritis) these medications are also known to cause severe, sometimes life-threatening adverse effects within the body, particularly in the gastrointestinal tract. A novel anti-inflammatory drug being developed and commercialized...

For many years it's been known that the fever, achiness and other symptoms you feel during the flu are triggered by a viral molecule that travels through the body acting like a toxin. But what scientists haven't understood is how this molecule "“ known as double-stranded RNA "“ is recognized and taken up by cells. New research from McMaster University has identified how specific proteins on the surface of cells, known as class A scavenger receptors, bind to double-stranded RNA and...

If you're the type of person who invokes the "not enough time" clause when it comes to exercising, it's time to find a new excuse. Researchers who have been studying interval training have found that it not only takes less time than what is typically recommended, but the regimen does not have to be "all out" to be effective in helping reduce the risk of such diseases at Type 2 diabetes. The study appears in the March issue of The Journal of Physiology. "What we've been able to show is that...

Hamilton, ON -- For some Canadians, any cut such as from dental work or surgery can cause days or more of bleeding. Although they are not hemophiliacs, for some an ordinary bruise can balloon into the size of an orange. For others, knees, elbows and ankles are crippled when bleeding seeps into joints. In very serious cases, hundreds of blood transfusions are required for recovery. Now a team led by McMaster University hematologist Dr. Catherine Hayward has discovered the genetic cause of...

McMaster researchers find cheaper therapy works better for women An intense three-week course of radiation therapy is just as effective as the standard five-week regimen for women with early-stage breast cancer. Dr. Tim Whelan, a professor of oncology of the Michael G. DeGroote School of Medicine at McMaster University, led a team of researchers to find that women who received the accelerated therapy have a low risk of the breast cancer for as long as 12 years after treatment. The results are...

Despite growing public interest in concussions because of serious hockey injuries or skiing deaths, a researcher from McMaster University has found that we may not be taking the common head injury seriously enough. In a study to be published in the February issue of the journal Pediatrics, Carol DeMatteo, an associate clinical professor in the School of Rehabilitation Science, found that children who receive the concussion label spend fewer days in hospital and return to school sooner than...

A Nobel-winning process for testing new drugs to treat diseases such as Huntington's, Parkinson's, and muscular dystrophy is getting an electrical charge. Researchers at McMaster University have developed a way to propel and direct microscopic-sized worms (C. elegans nematodes) along a narrow channel using a mild electric field. The discovery opens up significant possibilities for developing high-throughput micro-screening devices for drug discovery and other applications. "This is the first...

A McMaster University researcher has found the first evidence that prolonged exposure to higher levels of the pollutants found in car exhaust fumes and industrial air pollution can lead to hospitalization for pneumonia in adults aged 65 and older. Infectious disease specialist Mark Loeb led a research team to assess the effect of long-term exposure to nitrogen dioxide and sulfur dioxide, both found in motor vehicle emissions, and fine particulate matter, found in industrial air pollution, on...
