A mutant hen egg white lysozyme, D52E, was designed to correspond to the structure of the mutant T4 lysozyme T26E (Kuroki, R., Weaver, L. H., and Matthews B. W. (1993) Science 262, 2030-2033) to investigate the role of the catalytic residue on the alpha-side of the saccharide in these enzymes. The D52E mutant forms a covalent enzyme-substrate adduct, which was detected by electron ion spray mas...

conclusions it seems that there is no significant relationship between the side-lying endurance test and abdominal muscles thickness. patients and methods a convenience sample of 55 subjects, aged 20 - 30 years, participated in this study. endurance of abdominal muscles was measured using side-lying endurance test in all subjects. ultrasound thickness measurement for the transverses abdominis (...

We assess whether the White test is better than the conventional bile leakage test for the intraoperative detection of bile leakage in hepatectomized patients. This study included 30 patients who received elective liver resection. Both the conventional bile leakage test (injecting an isotonic sodium chloride solution through the cystic duct) and the White test (injecting a fat emulsion solution...

background: routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. we figure that repeat testing of critical laboratory values has any benefits or not.   methods : we examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white b...
