Measurement of lactate levels is important in the care of critically ill adult and pediatric patients. We compared 3 whole blood lactate methods (Radiometer ABL 725, Radiometer Medical A/S, Bronshoj, Denmark; i-STAT, i-STAT, East Windsor, NJ; and Nova Lactate Plus, Nova Biomedical, Waltham, MA) with 2 plasma-based methods (Roche Integra, Roche Diagnostics, Indianapolis, IN; and Vitros, Ortho Cl...

To the Editor: Recently, our laboratory received a bulletin (Technical Bulletin CC06001, Calcium C.f.a.s. Set Point and PNU/PPU Target Value Reassignments: All Clinical Chemistry Systems, January, 2006) from Roche Diagnostics Australia indicating that the calcium value of their calibrator for automated systems (C.f.a.s.) had been reassigned. According to the bulletin, the calibration was perfor...

We examine the evolution of residual gas within tidally-limited dwarf galaxies and globular clusters. In systems where the gas sound speed exceeds about 10% of the central velocity dispersion, hydrostatic equilibrium causes the gas to have significant density at the tidal radius. In contrast to the stellar component, gas particles relax rapidly in response to mass loss. Gas lost through the Lag...
