Structure and Signaling Mechanisms of G Protein-Coupled and b-Arrestin-Biased Chemokine Receptors
IIG Seminar
Most chemokine receptors are G Protein-Coupled Receptors (GPCRs), and are best known for their role in controlling cell migration in the context of immune system function. They are also implicated in many diseases particularly inflammatory diseases as well as cancer and HIV, making them important therapeutic targets. Recent structural and biophysical studies have revealed that the recognition interface between chemokines and receptors is very large and characterized by more complex epitopes than previously believed. In this presentation, our current understanding of how chemokines bind and activate their recept...

Novel Light-Based Technologies for the Detection, Diagnosis, and Selective Removal of Dental Decay
NIDCR Grand Rounds
High-precision light-based technologies are leading the way to a new era of minimally invasive dentistry. Optical methods developed by Dr. Daniel Fried ’ s group can instantly image dental caries, an approach shown to have higher performance than X-rays for diagnosis of tooth decay. Novel diagnostic and therapeutic devices built by Dr. Fried ’ s team take advantage of the optical properties of hard tissues exposed to long wavelengths of light in the near-infrared and infrared. Dental enamel becomes highly transparent near an infrared wavelength of 1300 nm, which is ideally suited for capturing images...

" Ice stripes " in a new anti-frosting surface could help solve a billion-dollar problem
In a new study, a passive anti-frosting surface fashioned out of an aluminum sheet provides a proof of concept for keeping surfaces 90 percent dry and frost free indefinitely -- all without any chemicals or energy inputs. The material manages this thanks to "ice stripes" -- microscopic raised ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)
