NHGRI targets 12 more organisms for genome sequencing

...sceptibility. They are: sequencing the genome of a fellow primate, the marmoset (Callithrix jacchus); and identification of genetic variations (in the form of single nucleotide polymorphisms) in eight strains of rats. The marmoset is a key model organism used in neurobiological studies of multiple sclerosi...

Chronic Sinus Infection Thought To Be Tissue Issue, Mayo Clinic Scientists Show It's Snot

...n. To conduct this investigation, Dr. Ponikau and fellow researchers collected specimens from 22 consecutive Mayo Clinic chronic sinus infection patients undergoing endoscopic sinus surgery. The surgeons extracted the maximum possible tissue and mucus during the sinus surgery. The surgeons also extracted t...

Study Finds Moderate Hypothermia A Safe Treatment For Traumatic Brain Injury In Kids

... Pittsburgh neurosurgeon P. David Adelson, MD, and fellow researchers determined that induced moderate hypothermia initiated after severe traumatic brain injury (TBI) is a safe therapeutic intervention for children. TBI initiates several metabolic processes that can exacerbate the injury. Adult research ha...

New method shows it is possible to grow bone for grafts within a patient's body

...om who did most of the research as a post-doctoral fellow at MIT, "and since the harvested bone is fresh it integrates really well at a recipient site." Long bones in the body are covered by a thin outer layer called the periosteum. The layer is a little like scotch tape: the outside is tough and fibrous b...
