Common human papillomavirus (HPV) genotypes in northern India are primarily HP-16 and HP-18. These types cause 75 percent of cervical cancers in the region, according to researchers.
Cold Spring Harbor Laboratory scientists uncover a large cache of genes that act as built-in barriers against cancer, including over 10 new tumor suppressor genes. The study reveals that even partial loss of function in these genes can accelerate tumor growth.
Researchers at Duke University have successfully grown a three-dimensional 'patch' of heart muscle cells using embryonic stem cells and a novel mold design. The patch exhibited the ability to contract and conduct electrical impulses, crucial attributes of native heart muscle cells.
