Tracking the NO signaling pathway

26-Aug-2021 - Both nitric oxide (NO) and hydrogen sulfide (H2S) act as gaseous signaling molecules with similar physiological effects. Many of the critical questions about the interplay between these two gasotransmitters hinge on their chemical reactivity and the fleeting existence of HSNO, a key product of ...

By decoding how HPV causes cancer, researchers find a new potential treatment strategy

04-Oct-2017 - A study that teases apart the biological mechanisms by which human papillomaviruses (HPV) cause cancer has found what researchers at Georgetown University Medical Center say is a new strategy that might provide targeted treatment for these cancers. HPV is responsible for the majority of cervical ...

Blood test helps guide treatment and can impact quality of life for breast cancer patients

16-Sep-2009 - With the goal of tailoring cancer interventions for the individual, researchers at the Lombardi Comprehensive Cancer Center at Georgetown have published the results of a prospective study that validates the use of a simple blood test to help doctors more reliably assess treatment effectiveness ...

Alternative to high cost palladium catalysts?

10-Mar-2009 - Scientists in the USA have developed a ligand-free copper catalysed procedure for carbon-nitrogen bond formation. Christian Wolf and Hanhui Xu from Georgetown University, Washington, in the US, show that carbon-nitrogen bond formation can be achieved in high yield by a copper catalysed coupling ...

A sub-femtosecond stop watch for 'photon finish' races

17-Mar-2008 - Using a system that can compare the travel times of two photons with sub-femtosecond precision, scientists at the Joint Quantum Institute (a partnership of the National Institute of Standards and Technology (NIST) and the University of Maryland) and Georgetown University have found a remarkably ...
