We sought to examine the effects of varicella-zoster virus (VZV) infection on the expression of major histocompatibility complex class I (MHC I) molecules by human fibroblasts and T lymphocytes. By flow cytometry, VZV infection reduced the cell surface expression of MHC I molecules on fibroblasts significantly, yet the expression of transferrin receptor was(More)
Varicella immunization provided the opportunity to examine the kinetics of interleukin (IL)-10, IL-12 and interferon (IFN)-gamma production elicited during primary in vivo sensitization with proteins of varicella-zoster virus (VZV), a common human herpesvirus. VZV-specific IFN-gamma release and T cell proliferation were elicited by immunization and(More)
B7-H1 [programmed death-ligand-1 (PD-L1)] is a B7-family member that binds to programmed death-1 (PD-1). Recently, deficiency of PD-L1 has been demonstrated to result in accelerated gastric epithelial cell damage in gastritis, and PD-L1 is suggested to play a critical role in regulating T cell homeostasis. Here, we aimed to gain more insight into gastric(More)
To enable a mobile robot to perform intervention or service tasks in a remote environment, the robot should be able to learn the unknown world and execute high level task commands from the operator. In this paper an interactive modeling of man-made environment from a single camera is presented. In this model the geometrical, topological and semantic(More)
A 36-year-old male patient was scheduled to undergo ureteroscopic lithotomy because of left ureteral stone under spinal anesthesia. After receiving a renewed spinal anesthesia with 8 mg tetracaine to compensate for the first attempt (with 10 mg tetracaine), which proved to be a failure, he was soon seized with episodic seizure attacks. Central nervous(More)
A case of pneumocephalus and respiratory depression after dural puncture during lumbar epidural analgesia is reported. The loss of resistance to air technique was employed to identify the epidural space. Severe respiratory depression and stuporous consciousness developed one hour after a bolus of 2 mg morphine was given epidurally at the end of operation.(More)
Due to the development of newer generation of lithotriptor, the anesthesia for extracorporeal shock wave lithotripsy (ESWL) was variable recently. To compare opioid analgesia with epidural lidocaine for their efficacy in pain control, hemodynamic changes, side effects and patient acceptance during ESWL, sixty unpremedicated patients undergoing elective ESWL(More)
Accelerated reversal of moderate neuromuscular blockade has been reported to be effective by giving anticholinesterase in divided doses (priming reversal). To evaluate its effectiveness in profound blockade, forty ASA physical status I or II patients were studied. After receiving 0.5mg/kg of atracurium during N2O-O2-halothane anesthesia, they were reversed(More)
