The aim of this study was to establish a culture system to support the growth of bovine oocytes as enclosed in granulosa cell complexes that extend on a flat substratum. Such systems have been established for mouse oocytes but are not applicable to larger animals because it is difficult to maintain an appropriate association between the oocyte and companion(More)
This review describes the fish immune system, focusing on specific cell-mediated immunity. Specific in vivo cell-mediated immune responses have been shown by allograft rejection, graft-versus-host reaction (GVHR) and delayed hypersensitivity reaction (DTH). Recent in vitro studies also showed specific cell-mediated cytotoxicity against allogeneic target(More)
Temperature dependence of toluene decomposition behavior was investigated with a two-stage discharge and ozone-catalyst hybrid reactor. Temperature was varied from 20 to 200degC because VOC exhausts from painting and printing facilities reach this temperature level. A synergistic effect of discharge and catalysts was observed for toluene conversion at(More)
The temperature dependence of toluene decomposition behavior was investigated with a two-stage discharge and ozone-decomposition-catalyst hybrid reactor. Toluene conversion jumped by four times by adding catalyst to the discharge at ambient temperature. This synergistic effect diminished with an increase in temperature, and no synergy was observed at higher(More)
