A shift three-source model is used in this paper to describe the multiplicity and the pseudorapidity distributions of final-state charged particles produced in proton-proton collisions at energies available at the Large Hadron Collider (LHC). The three kinds of sources are central sources arising from gluon-gluon collisions, target fragmentation sources arising from gluon- or quark-induced collisions with target quarks, and projectile fragmentation sources arising from gluon- or quark-induced collisions with projectile quarks. The central, target fragmentation, and projectile fragmentation sources each have shifts around their centers. The results calculated by using the shift three-source model are in agreement with the experimental data of the ALICE (A Large Ion Collider Experiment) and the CMS (Compact Muon Solenoid experiment) Collaborations.

In this paper, the kinetics of a cloned special glucosidase, named ginsenosidase type III hydrolyzing 3-O-glucoside of multi-protopanaxadiol (PPD)-type ginsenosides, were investigated. The gene (bgpA) encoding this enzyme was cloned from a Terrabacter ginsenosidimutans strain and then expressed in E. coli cells. Ginsenosidase type III was able to hydrolyze 3-O-glucoside of multi-PPD-type ginsenosides. For instance, it was able to hydrolyze the 3- O-β-D-(1→2)-glucopyranosyl of Rb1 to gypenoside XVII, and then to further hydrolyze the 3-O-β-D-glucopyranosyl of gypenoside XVII to gypenoside LXXV. Similarly, the enzyme could hydrolyze the glucopyranosyls linked to the 3-O- position of Rb2, Rc, Rd, Rb3, and Rg3. With a larger enzyme reaction Km value, there was a slower enzyme reaction speed; and the larger the enzyme reaction Vmax value, the faster the enzyme reaction speed was. The Km values from small to large were 3.85 mM for Rc, 4.08 mM for Rb1, 8.85 mM for Rb3, 9.09 mM for Rb2, 9.70 mM for Rg3(S), 11.4 mM for Rd and 12.9 mM for F2; and Vmax value from large to small was 23.2 mM/h for Rc, 16.6 mM/h for Rb1, 14.6 mM/h for Rb3, 14.3 mM/h for Rb2, 1.81mM/h for Rg3(S), 1.40 mM/h for Rd, and 0.41 mM/h for F2. According to the Vmax and Km values of the ginsenosidase type III, the hydrolysis speed of these substrates by the enzyme was Rc>Rb1>Rb3>Rb2>Rg3(S)>Rd>F2 in order.

<P><B>Abstract</B></P><P>A graph is half-arc-transitive if its automorphism group acts transitively on vertices and edges, but not on arcs. It is known that for a prime p there is no tetravalent half-arc-transitive graphs of order p or <SUP>p2</SUP>. Xu [M.Y. Xu, Half-transitive graphs of prime-cube order, J. Algebraic Combin. 1 (1992) 275–282] classified the tetravalent half-arc-transitive graphs of order <SUP>p3</SUP>. As a continuation, we classify in this paper the tetravalent half-arc-transitive graphs of order <SUP>p4</SUP>. It shows that there are exactly p−1 nonisomorphic connected tetravalent half-arc-transitive graphs of order <SUP>p4</SUP> for each odd prime p.</P>

Purpose Nonylphenol (NP) is an endocrine disruptor found in products such as cleaners, plastics, and detergents. It exerts actions similar to endogenous 17-estradiol (E2) and is reported to influence various cancers. However, its role in colon cancer remains elusive. Materials and Methods Colon cancer cell lines COLO 205 and SW480 were employed in our study. The cells were treated with NP or E2 followed by measurement of apoptosis and proliferation using flow cytometry and MTT assays, respectively. G protein–coupled estrogen receptor 30 (GPR30) expression was visualized using immunofluorescence and Western blot. To investigate the underlying mechanism, the expression levels of GPR30, p-protein kinase A (PKA), c-myc, cyclin D1, and ERK1/2 were analyzed using Western blot. Meanwhile, the GPR30 antagonist G15 was utilized to validate the role of GPR30 in colon cancer progression. Finally, the effect of a GPR30 inhibitor on tumor growth was determined in vivo using tumor xenograft mouse models. Results NP facilitated the proliferation of colon cancer cells and induced apoptosis failure in vitro. Western blot revealed increased GPR30 expression levels in response to NP treatment. Cyclin D1, p-PKA, c-myc, and proliferating cell nuclear antigen, proteins that regulate the cell cycle, were all upregulated by NP, and NP-mediated ERK1/2 activation and subsequent cell proliferation were abrogated by the GPR30 inhibitor G15. Moreover, colon cancer mice that received G15 administration demonstrated impaired tumor growth in vivo. Conclusion Low dose NP promotes the growth of colon tumors through GPR30-mediated activation of ERK1/2 signaling.

<P>A graph is s-regular if its automorphism group acts regularly on the set of its s-arcs. Malnič et al. (Discrete Math 274 (2004), 187–198) classified the connected cubic edge-transitive, but not vertex-transitive graphs of order 2p<SUP>3</SUP> for each prime p. In this article, we determine the s-regularity of all connected cubic symmetric graphs of order 2p<SUP>3</SUP> for each prime p and each s. © 2006 Wiley Periodicals, Inc. J Graph Theory</P>

Objective: The study investigated the biological functions and mechanisms for controlling cashmere growth of Liaoning cashmere goat by ovarian carcinoma immunoreactive antigen-like protein 2 (OCIAD2) and decorin (DCN) genes. Methods: cDNA library of Liaoning cashmere goat was constructed in early stages. OCIAD2 and DCN genes related to cashmere growth were identified by homology analysis comparison. The expression location of OCIAD2 and DCN genes in primary and secondary hair follicles (SF) was performed using in situ hybridization. The expression of OCIAD2 and DCN genes in primary and SF was performed using real-time polymerase chain reaction (PCR). Results: In situ hybridization revealed that OCIAD2 and DCN were expressed in the inner root sheath of Liaoning cashmere goat hair follicles. Real-time quantitative PCR showed that these genes were highly expressed in SF during anagen, while these genes were highly expressed in primary hair follicle in catagen phase. Melatonin (MT) inhibited the expression of OCIAD2 and promoted the expression of DCN. Insulin-like growth factors-1 (IGF-1) inhibited the expression of OCIAD2 and DCN, while fibroblast growth factors 5 (FGF5) promoted the expression of these genes. MT and IGF-1 promoted OCIAD2 synergistically, while MT and FGF5 inhibited the genes simultaneously. MT+IGF-1/MT+FGF5 inhibited DCN gene. RNAi technology showed that OCIAD2 expression was promoted, while that of DCN was inhibited. Conclusion: Activation of bone morphogenetic protein (BMP) signaling pathway up-regulated OCIAD2 expression and stimulated SF to control cell proliferation. DCN gene affected hair follicle morphogenesis and periodic changes by promoting transforming growth $factor-{\beta}$ ($TGF-{\beta}$) and BMP signaling pathways. OCIAD2 and DCN genes have opposite effects on $TGF-{\beta}$ signaling pathway and inhibit each other to affect the hair growth.
Photoelectrocatalytic Degradation of Dyes in Aqueous Solution Using CNT/TiO₂ Electrode

The effect of photoelectrocatalytic (PEC) degradation for different dyes with the CNT/TiO₂ electrode was studied. The prepared electrode was characterized with surface properties, structural crystallinity, elemental identification, and PEC activity. The N2 adsorption data showed that the composites had decreased surface area compared with the pristine CNT. This indicated the blocking of micropores on the surface of CNT, which was further supported by observation via FESEM. XRD patterns of the composites showed that the CNT/TiO₂ composite contained a mixing anatase and rutile phase. EDX spectra showed the presence of C, O and Ti peaks for all samples. The decomposition efifciency of the prepared electrode was evaluated by the PEC degradation of three dyes (methylene blue (MB), rhodamine B (RH.B), methyl orange (MO)). The variations of the FT-IR spectra and pH value of dye solutions were measured during the PEC system; it was found that the CNT/ TiO₂ electrode has better PEC degradation for MB solution than that of RH.B and MO. The proposed degradation mechanism was present.
