15-year hunt finds cause of pseudothalidomide syndrome

...any or too few chromosomes (a problem also seen in cancer cells). In Roberts syndrome, the cells tend to stop growing or die, precluding proper development of the limbs, palate and other structures.

UCLA study assesses cost-effectiveness of Hepatitis B drugs

... B disease can lead to liver failure, cirrhosis or cancer of the liver. About 90 percent of healthy adults who are infected with Hepatitis B recover with no problems, but 10 percent develop chronic disease. In children who have been infected, 60 percent develop chronic disease. Other authors include Dr. Ia...

Researchers test new therapy for advanced melanoma

Melanoma is a particularly deadly form of skin cancer very resistant to treatment. Researchers at H. Lee Moffitt Cancer Center & Research Institute and the University of South Florida are testing a promising new therapy that prompts the immune system to aid in the fight against melanoma tumors. "Th...

Dr. Porteus' strategy differs fundamentally from previous gene therapies because it essentially replicates the natural process, which is more accurate. This accuracy means that, in practice, the gene therapy only affects the mutant gene. Homo...
