Aberrantly expressed microRNAs contribute to the initiation and progression of human cancers. However, the underlying functions of microRNA-187 (miR-187) in colorectal cancer (CRC) remain largely unexplored. Here, we demonstrated that miR-187 was significantly down-regulated in CRC tissues and cell lines compared to their normal counterparts. By Kaplan-Meier analysis, we revealed that decreased...

Irradiation of polymers is one of the most effective and economical methods for modifying their properties and for changing their applications. In this study, an extrusion grade polypropylene (PP) was treated by electron beam irradiation to produce a PP suitable for injection molding. Irradiation was carried out at different doses (0-80 kGy) under atmosphere air and at ambient temperature. Melt...

The firefighter problem is the following discrete-time game on a graph. Initially, a fire starts at a vertex of the graph. In each round, a firefighter protects one vertex not yet on fire, and then the fire spreads to all unprotected neighbors of the vertices on fire. The objective of the firefighter is to save as many vertices as possible. The surviving rate of a graph is the average percentag...

Most papers in the second group are concerned with technical questions. Rainer Degen gives an annotated conspectus (pp. 131-166: German) of Syriac translations of Galen known to have existed once, with valuable information on material at present known to be extant (much of it extracts in the Syriac book ofmedicines). Elinor Lieber (pp. 167-186: English) deals with Galen in the Hebrew tradition....

In light of the recent data from BES collaboration for χc0 → V V , PP and SS, and from CLEO-c for ηη, η′η′ and ηη′, we present a detailed analysis of the decays of heavy quarkonia into light meson pairs such as χc0,2 → V V , PP and SS in a recently proposed parametrization scheme. An overall agreement with the data is achieved in χc0,2 → V V and PP , while in χc0 → SS we find that a possible ex...
