Host cell proteases that cleave the hemagglutinin (HA) of influenza viruses in the human respiratory tract are still not identified. Here we cloned two human type II transmembrane serine proteases with known airway localization, TMPRSS2 and HAT, into mammalian expression vector. Cotransfection of mammalian cells with plasmids encoding HA and either protease(More)
Current American Dental Association infection control guidelines recommend immersion disinfection of irreversible hydrocolloid impressions, and this study further defines the parameters for use of sodium hypochlorite. Sodium hypochlorite has been shown to be an effective disinfectant for impressions; however, it has not been fully evaluated for optimum(More)
BACKGROUND For nerve stimulator-guided regional anesthesia, one has to compromise between a presumed low success rate (using a high-current threshold) and a presumed increased risk of nerve damage (using a low-current threshold). We hypothesized that high-current thresholds in the range of 0.9 to 1.1 mA are not inferior with respect to the procedural and(More)
Five tissue antigens have been identified which appear in carcinoma arising in the ovary. Antisera to a variety of human tissues were absorbed with a saline extract of normal ovary as well as plasma; five distinct antigens (A1-A4, TA) were detected in ovarian tumor extracts as well as in normal tissues. A1, A2, and A3 were widely distributed in normal(More)
Clinically relevant concentrations of isoflurane (ISO) and nitrous oxide (N2O) enhance chloride currents induced by activating gamma-aminobutyric acid(A) receptors (GABA(A)R). Channel blocking by ISO overcomes the enhancing effect at higher concentrations. In this study, the effect of coadministered ISO and N2O on responses evoked by GABA in transfected(More)
Thermostable antigen (TA) occurs in ovarian carcinoma and in certain specialized tissues. High titers of TA were found in nineteen of twenty endocervical extracts but not in myometrium, endometrium, or exocervix. TA was present in all of sixteen cervical mucus samples. Antibodies to perchloric acid extract of bronchus showed cross-reaticity with TA from(More)
