Donated red blood cells lose a key feature that diminishes their lifesaving power the longer they have been stored, according to researchers at Duke University Medical Center.
Unlike the rest of the cells in your body, your red blood cells lack nuclei.
Taking gold nanoparticles to the cancer cell and hitting them with a laser has been shown to be a promising tool in fighting cancer, but what about cancers that occur in places where a laser light can't reach? Scientists at the Georgia Institute of Technology have shown that by directing gold nanoparticles into the nuclei of cancer cells, they can not only prevent them from multiplying, but can kill them where they lurk. The research appeared as a communication in the February 10 edition of the Journal of the American Chemical Society.
Over a century since scientists first observed that cells and their nucleus grow at a constant ratio to each other, we are now closer to finding out how.
Genetically identical cells do not always behave the same way. According to the accepted theory, the reason are random molecular processes - known as random noise. For decades this view has been underpinned by numerous experiments and theoretical models.
Transcription factors, the tiny proteins that switch genes on or off in the nucleus of cells, are considered unreachable molecular targets for drugs attempting to treat medical conditions.
Cochlear Limited, the global leader in implantable hearing solutions, announced today that the U.S. Food and Drug Administration (FDA) has approved the Cochlear™ Nucleus® 6 Sound Processor for use with the Nucleus 22 Cochlear Implant, giving those who have worn cochlear implants from the beginning (over 20 years in some cases) access to the latest breakthroughs in true wireless and automatic hearing. Released in 1985, the Nucleus 22 Implant was the first commercially available multi-channel cochlear implant in the world.
Sensory neurons have always put on a good show. But now it turns out they'll be sharing the credit. In groundbreaking research to appear in the October 31 issue of Science, Rockefeller University scientists show that while neurons play the lead role in detecting sensory information, a second type of cell, the glial cell, pulls the strings behind the scenes.
