Penn-led Study: Children With Respiratory Failure Can Be Awake Yet Comfortable in ICU

blurb: 
Standard practice in hospitals is to fully sedate children on ventilators for their comfort and safety, but a new study shows that lighter, more finely-tuned sedation can be just as effective.

For small children, being hospitalized is an especially frightening experience above and beyond the challenges of whatever they are being treated for. They are often connected to a variety of unpleasant tubes and monitors, which they may instinctively try to remove.

Researchers at Penn, Berkeley and Illinois Use Oxides to Flip Graphene Conductivity

Graphene, a one-atom thick lattice of carbon atoms, is often touted as a revolutionary material that will take the place of silicon at the heart of electronics. The unmatched speed at which it can move electrons, plus its essentially two-dimensional form factor, make it an attractive alternative, but several hurdles to its adoption remain.

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.
