In fall 2009, the Bill & Melinda Gates Foundation launched the Measures of Effective Teaching (MET) project to test new approaches to measuring effective teaching. The goal of the MET project is to improve the quality of information about teaching effectiveness available to education professionals within states and districts— information that will help them(More)
A hydraulically activated bone chamber model was utilized to investigate cellular and microstructural mechanisms of mechanical adaptation during bone repair. Woven trabecular bone and fibrotic granulation tissue filled the initially empty chambers by 8 weeks postimplantation into canine tibial and femoral metaphyses. Without mechanical stimulation, active(More)
8-Chloro-6-(2-fluorophenyl)-1-methyl-4H-imidazol[1,5-a][1,4]benzodiazepine (midazolam maleate, Ro 21-3981, Dormicum) or thiopental were administered to 99 women undergoing short gynecological surgical procedures for induction and maintenance of anesthesia along with 67% nitrous oxide. Either fentanyl 1.5 microgram kg-1 or a saline placebo were given i.v. as(More)
An etomidate infusion regimen for hypnosis as part of balanced, totally intravenous anesthesia was designed to maintain plasma etomidate concentrations above the awakening concentration of 300 ng/ml while avoiding dose-related side effects. The etomidate infusion regimen of 0.1 mg/kg/min for 3 min, 0.02 mg/kg/min for 27 min, and 0.01 mg/kg/min for the(More)
In a randomized, double blind study of 75 adult surgical patients, nalbuphine (0.1 mg/kg), morphine (0.1 mg/kg), or a placebo were administered intravenously as premedication 12 to 16 minutes prior to induction of anesthesia. Comparison of the 3 groups showed: (1) patients receiving nalbuphine and morphine had a significant reduction of minute ventilation(More)
Premedication with lorazepam (4 mg), diazepam (10 mg), and a placebo was compared in a randomized, double-blind study of 95 adult surgical patients. Comparisons were made of recall of a memory card and events of the operative day, relief of anxiety, degree of somnolence, effects on blood pressure and heart rate, and incidence of side effects. Lorazepam(More)
Midazolam kinetics were determined in 11 younger (22 to 30 yr) and 11 older (50 to 60 yr) women to determine age-related differences in the kinetics of this water-soluble benzodiazepine. Midazolam, 0.2 mg/kg, was injected intravenously over 30 sec for induction of anesthesia that was maintained with 67% nitrous oxide in oxygen and intravenous fentanyl(More)
Trabecular bone adaptation adjacent to porous-coated platen implants embedded within canine distal femoral metaphyses was evaluated following 24 weeks of daily compressive loading. The in vivo experimental model delivered controlled loads to five different platen implant topologies with variations in platen shape and porous coating distribution. Adaptive(More)
