Frontline health workers essential for newborn survival

"An infant's first moments and the twenty-eight days that follow are the most precarious, and her risk of death is never higher," but "[s]imple and inexpensive techniques, ... such as drying her, clearing her airway, keeping her warm or using a simple ventilation device to stimulate her breathing, can help," and frontline health workers "deliver these lifesaving techniques."

Researchers identify subgroups of B cells in MYC-positive germinal centers

Germinal centers are sites in the organs of the lymphatic system, formed during the course of an immune response to infection, where B cells intensely proliferate and modify their DNA in order to produce antibodies specific for the pathogen. However, it is known that the vast majority of lymphomas derive from the B cells at the germinal centers.

Latest research on stem cells discussed at Einstein symposium

The promise of stem cells seems limitless. If they can be coaxed into rebuilding organs, repairing damaged spinal cords and restoring ravaged immune systems, these malleable cells would revolutionize medical treatment. But stem cell research is still in its infancy, as scientists seek to better understand the role of these cells in normal human development and disease.
