Abstract: A probiotic composition for improving an effect of a chemotherapeutic drug of Gemcitabine on inhibiting pancreatic cancer is disclosed in the present disclosure. The probiotic composition comprises an effective amount of Lactobacillus paracasei GMNL-133, an effective amount of Lactobacillus reuteri GMNL-89, and a pharmaceutically acceptable carrier, wherein the Lactobacillus paracasei GMNL-133 was deposited in the China Center for Type Culture Collection on Sep. 26, 2011 under an accession number CCTCC NO. M 2011331, and the Lactobacillus reuteri GMNL-89 was deposited in the China Center for Type Culture Collection on Nov. 19, 2007 under an accession number CCTCC NO. M 207154. A method for improving the effect of the chemotherapeutic drug of Gemcitabine on inhibiting pancreatic cancer is further disclosed in the present disclosure.

Abstract: A supported metallocene catalyst includes a carrier and a metallocene component. The carrier includes an inorganic oxide particle and an alkyl aluminoxane material. The inorganic oxide particle includes at least one inorganic oxide compound selected from the group consisting of an oxide of Group 3A and an oxide of Group 4A. The alkyl aluminoxane material includes an alkyl aluminoxane compound and an alkyl aluminum compound that is present in amount ranging from greater than 0.01 wt % to less than 14 wt % base on 100 wt % of the alkyl aluminoxane material. The metallocene component is supported on the carrier, and includes one of a metallocene compound containing a metal from Group 3B, a metallocene compound containing a metal from Group 4B, and a combination thereof. A method for preparing the supported metallocene catalyst and a method for preparing polyolefin using the supported metallocene catalyst are also disclosed.

Abstract: An electronic connector includes: a pair of pivotal latches pivotaly mounted on two opposite end portions of the electronic connector, each pivotal latch smoothly engageable with a side recess or opening formed in a right or left end portion of the daughter board, whereby upon a pivotal movement of each latch by biasing each latch sidewardly outwardly to disengage the latch from the daughter board, the daughter board can be easily quickly removed from the connector for maintenance and the like.
