Penn Dental Medicine Team Shows Why Wound Healing Is Impaired in Diabetics

blurb: 
Scientists at the University of Pennsylvania School of Dental Medicine have identified a critical molecule that helps explain why diabetics suffer from slow wound healing and pinpoints a target for therapies that could help boost healing.

One of the most troubling complications of diabetes is its effect on wound healing. Roughly 15 percent of diabetics will suffer from a non-healing wound in their lifetime. In some cases, these open ulcers on the skin lead to amputations.

Penn Research Shows Relationship Critical for How Cells Ingest Matter

To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually encapsulates the material in a bubble called a vesicle.

Penn Engineers Develop Graphene-based Biosensor That Works in Three Ways at Once

One of nanotechnology’s greatest promises is interacting with the biological world the way our own cells do, but current biosensors must be tailor-made to detect the presence of one type of protein, the identity of which must be known in advance.

Twitter Can Predict Rates of Coronary Heart Disease, According to Penn Research

blurb: 
Penn researchers have now shown that the social media platform Twitter can serve as a dashboard indicator of a community’s psychological well being and can predict rates of heart disease.

Twitter has broken news stories, launched and ended careers, started social movements and toppled governments, all by being an easy, direct and immediate way for people to share what’s on their minds.

Penn Scientists Identify Patterns of RNA Regulation in the Nuclei of Plants

blurb: 
In a new study done in plants, University of Pennsylvania biologists give a global view of the patterns that can affect the various RNA regulatory processes that occur before these molecules move into the cytoplasm, where they are translated into the proteins that make up a living organism.

When the human genome was first sequenced, experts predicted they would find about 100,000 genes. The actual number has turned out to be closer to 20,000, just a few thousand more than fruit flies have. The question logically arose: how can a relatively small number of genes lay the blueprint for the complexities of the human body?
