The Molybdenum Cofactor: Modeling the Swiss Army Knife of Metabolic Diversity
<p>The pterin-dithiolene ligand (MPT), uniquely found in mononuclear molybdenum (Mo) and tungsten (W) enzymes, continues to intrigue us. The complexity of this ligand has been suggested as a cog in Mo and W enzyme function, and the pterin has been increasingly appreciated for its electronic …

A Complete Dosimetric Model of the Gamma Knife Perfexion Using Penelope Monte Carlo Codes
The Gamma Knife Perfexion is a radiosurgical treatment device used to irradiate targets in the head. It uses 192 high-activity Cobalt-60 sources collimated to a common focus to impart radiological damage to the target structure while minimizing dose to adjacent healthy tissue. Tungsten collimators …
