MUHC scientists describe genetic resistance to rampant virus

...HIV patients and improve the success of transplant surgery by reducing the risk of rejection. There is currently no treatment or cure for CMV. Resistance to diseases like CMV depends, at least partially, on the ability of our body's defense mechanism to recognize and destroy them. "Detecting these pathogens...

Nano-bumps could help repair clogged blood vessels

... inside arteries to prop them open during or after surgery to remove dangerous plaque deposits from the vessels. The stents, which are made of titanium and other metals, enable the arteries to grow new tissue after vessel-clogging plaque deposits have been removed. A major problem, however, is that the body ...

Chemicals in tattoo inks need closer scrutiny
