Stating that sleep is an essential biological process seems as obvious as saying that the sun rises every morning. Yet, researchers' understanding of the molecular mechanisms underlying the effects of sleep loss is still in its earliest stages.

Penn Medicine researchers have begun a new immunotherapy trial with the “checkpoint inhibitor” known as pembrolizumab in patients with oligometastatic lung cancer—a state characterized by a few metastases in a confined area—who have completed conventional treatments and are considered free of active disease but remain at a high risk for recurrence.

Peripheral nerve injury (PNI) is a common consequence of traumatic injuries, wounds caused by an external force or an act of violence, such as a car accident, gun shot or even surgery. In those injuries that require surgical reconstruction, outcomes  can result in partial or complete loss of nerve function and a reduced quality of life. But, researchers at Penn Medicine have demonstrated a novel way to regenerate long-distance nerve connections in animal models using tissue-engineered nerve grafts (TENGs).
