High purity amphotericin B.

OBJECTIVES Amphotericin B (AmB) is a drug of choice for treatment of disseminated fungal infections, but its use is often associated with severe adverse effects. Our observation that generic formulations of AmB contain multiple polyene components led us to propose that removal of other polyenes would yield a high purity AmB (AmBHP) with an improved therapeutic index. METHODS To test that prem...

Performance Characteristics of a Third-generation Spectroscopic Vehicle Portal Monitor based on High Purity Germanium Detectors

The general need for improved detection performance and reduced decision time for portal monitors, freight container scanners, and mobile search systems is being achieved with systems utilizing High-Purity Germanium (HPGe) detectors. Highly specialized software analyzes the spectroscopic data to produce accurate results in live time. To meet the need, a new generation monitor has been developed...
