A team of researchers has successfully regenerated rabbit joints using a cutting-edge process to form the joint inside the body, or in vivo. Regenerative in vivo procedures are performed by stimulating previously irreparable organs or tissues to heal themselves. In this study, bioscaffolds, or three-dimensional structures made of biocompatible and biodegradable materials in the shape of the tissue, were infused with a protein to promote growth of the rabbit joint.

Researchers assessed the geographical distribution of the long-term burden of post-traumatic stress disorder (PTSD) in a region of Liberia and report that the prevalence of PTSD remains high nearly two decades after the principal conflict there and five years after war in Liberia ended entirely. Particularly interesting was the geographic distribution of PTSD. Investigators found that certain villages in the region had a much higher prevalence of PTSD than did others.

In an effort to develop new therapies for pancreatic cancer, models of this disease must be created and characterized. A recent study from United States found that advanced magnetic resonance imaging methods could be used to differentiate living from dead tumor cells in a rabbit model of pancreatic cancer, thus providing a more in-depth understanding of this model of pancreatic cancer as well as the imaging methods employed.

A recent study examined weekly, customized text messages to remind adolescent diabetes patients about their personal treatment activities. An increase in overall treatment adherence and improved blood glucose levels was found.

Results from a new study suggest that oral contraceptives and hormone replacement therapy may yield additional benefit of protecting against the formation and rupture of brain aneurysms in women.
