Large-conductance Ca-activated potassium channels (BK channels) are uniquely sensitive to both membrane potential and intracellular Ca2+. Recent work has demonstrated that in the gating of these channels there are voltage-sensitive steps that are separate from Ca2+ binding steps. Based on this result and the macroscopic steady state and kinetic properties(More)
In this and the following paper we have examined the kinetic and steady-state properties of macroscopic mslo Ca-activated K+ currents in order to interpret these currents in terms of the gating behavior of the mslo channel. To do so, however, it was necessary to first find conditions by which we could separate the effects that changes in Ca2+ concentration(More)
The kinetic and steady-state properties of macroscopic mslo Ca-activated K+ currents were studied in excised patches from Xenopus oocytes. In response to voltage steps, the timecourse of both activation and deactivation, but for a brief delay in activation, could be approximated by a single exponential function over a wide range of voltages and internal(More)
The purpose of this study was to test the mutant selection window (MSW) hypothesis with Escherichia coli exposed to levofloxacin in a rabbit model and to compare in vivo and in vitro exposure thresholds that restrict the selection of fluoroquinolone-resistant mutants. Local infection with E. coli was established in rabbits, and the infected animals were(More)
During 2006–2008, twenty cases with sparganosis caused by eating live tadpoles emerged in Henan province, central China. To determine seroprevalence of anti-sparganum antibodies and obtain information about habits of eating live tadpoles and risks for sparganum infection, a serological survey was carried out in one village of Henan. Antisparganum IgG in 298(More)
Prediction and elucidation of pharmacogenetic effects is important for facilitating the development of personalized medicines. Knowledge of polymorphism-induced and other types of drug-response variations is needed for facilitating such studies. Although databases of pharmacogenetic knowledge, polymorphism and toxicogenomic information have appeared, some(More)
OBJECTIVE To investigate the prevalence of obesity in young adults and to analyze the influencing factors on renal functions and proteinuria in this population. METHODS This study comprised civil servants between 20 and 39 years old, who received physical examinations at the First Affiliated Hospital of Fujian Medical University. The subjects were(More)
Hybridomas secreting monoclonal antibodies (MAbs) against excretory-secretory (ES) antigen of Trichinella spiralis muscle larvae were produced. The 12 monoclones (designated 3A11, 7D9, 7F6, 5A7, 6H7, 39F3, 38H2, 37E7, 35B9, 29A11, 39C9 and 39A6) secreted IgM, IgG3 and IgG2b, respectively. Western blot using T. spiralis ES antigens showed that ten of 12 MAbs(More)
