A recent research has shown that many African Americans avoid getting screened for cancer hearing public service announcements and cancer news stories that highlight the fact that African Americans are often diagnosed with cancer at a later stage and have a lower survival rate as compared to whites.

London, November 7: A Canadian researcher team says that the efficacy of anti-cancer drugs in destroying tumours, or in keeping them in check, may be improved with the aid of a virus called reovirus.

Brad Thompson, CEO of Canadian company Oncolytics Biotech that has been developing the virus as a product called Reolysin, has revealed that this virus harmlessly infects most people at some time in their lives.

He says that the reovirus destroys tumour cells because they lack the cellular machinery that keeps the virus in check in healthy cells.

Washington, Nov 8 : People who develop kidney stones are at a greater risk of developing chronic kidney disease, according to a new study.

London, November 7 : Ingredients in plastic test tubes can block some biological reactions while testing the efficacy of drugs, and thereby lead researchers to bogus conclusions, according to a new study.

University of Alberta researcher Andrew Holt says that water alone can leach such chemicals out of plastic tubes.

He has revealed that the his team noticed the effect while testing experimental drugs that could potentially treat Parkinson''s disease.

According to him, his team’s work supports anecdotal evidence from various studies that plastics seem to affect some experiments.

Washington, November 7 : Duke University bioengineers say that gold nanostars may revolutionise medical diagnoses, and testing for environmental contaminants.

The researchers have revealed that their proposition is based on a comparison between all the shapes of nanoparticles studied to date, including rods, cones, cubes, and spheres.

They say that any such revolution would depend upon how light reflects off the particles, and nanostars can dramatically enhance the reflected light.

According to them, this increases their potential usefulness as a tracer, label, or contrast agent.
