Article focuses on new optical equipment that use laser beams to peer painlessly below your skin A hand-held scanner, similar to the fictional Superstar Trek medical Tricorder, pictures blood vessels through the skin and tasks a map onto your skin showing nurses wherever to place a needle facts about drugs . A pocket-sized device checks blood sugar through the skin of individuals with diabetes – no pinprick or blood sample needed. Those improvements are among a new genre of medical imaging technology that’s giving doctors and scientists noninvasive views in to the body to diagnose and research diseases. A report on this issue appears in today’s edition of Chemical substance & Engineering Information , the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.
Recently, however, scientists have found that not absolutely all transcribed RNA molecules become translated into proteins. In fact, studies show that large portions of the genome are transcribed into RNA that serve tasks other than working as blueprints for proteins. In 2010 2010, the Shiekhattar lab first released the discovery of these ncRNA enhancer molecules in the journal Cell :46-58), and theorized on their function as enhancers of gene expression. Since then, laboratories around the world have linked and released ncRNAs not only to transcriptional enhancers but also to certain illnesses, including some cancers.
