Probiotics, beneficial microorganisms best known for promoting gut health in humans, are now being used by Western University and Lawson Health Research Institute scientists to save honey bee colonies from collapse. A new study published in the Nature journal ISME J demonstrates how probiotics could potentially stave off a common bacterial hive infestation called American Foulbrood.
Prostate cancer can be elusive.
Wayne Smith’s journey with prostate cancer began 16 years ago when his family physician noticed increasing levels of prostate specific antigen (PSA) in his blood. PSA is a protein expressed by the prostate. A blood test is used to monitor levels of the protein as a screening tool for prostate cancer.
Researchers at Lawson Health Research Institute (Lawson) are developing a hand-held photoacoustic imaging probe to be used during breast conserving surgery to quickly and accurately verify if all cancerous tissue has been removed.
Surgeons currently do not have real-time technology to guide tumour removal during surgery.
Using current tools, there is a 20 per cent chance that cancerous cells will be left behind, risking recurrence and repeat surgery.
