Bird flu has jumped species barrier to cats The H5N1 strain of bird flu swept through 10 Parts of asia early this full year, leading to the death or slaughter of over 100 million chickens and the deaths greater than 20 people. Since mid-December 2003, Cambodia, China, Indonesia, Japan, Laos, South Korea, Vietnam and Thailand possess reported outbreaks of the avian influenza stress H5N1. Vietnam and Thailand possess reported influenza H5N1 infection in human beings with 32 laboratory-confirmed situations and 22 deaths, a mortality price of 70 % nearly.To day, CXCR4 has been associated with a lot more than 20 types of tumor. The Scripps Research researchers attempt to reveal how CXCR4 features by capturing snapshots of the proteins with a structure determination technique known as X-ray crystallography. To comprehend how organic molecules might bind and transmission through the receptor also to see how potential medicines could connect to it, they examined CXCR4 bound to known inhibitors of its activity.
