Toronto: Many drugs that target cancers cause nausea, a common and distressing side-effect with a sensation of unease and discomfort in the upper stomach, say researchers.Now researchers with the help of some "disgusted" rats have identified the mechanism that causes this, possibly opening the way to more effective management of nausea and vomiting linked with cancer treatment.Linda Parker, professor of behavioural neuroscience, University of Guelph, who conducted the research with doctoral student Katharine Tuerke and Cheryl Limebeer, said: "Although everyone has experienced nausea at some point, its neurobiology is poorly understood due to a lack of animal models," the Journal of Neuroscience reported."We know about vomiting. The vomiting reflex is very well characterized, but the experience of nausea is something that little is known about. How is it generated? Where is it generated?" Parker added, according to a Guelph statement.
