Energy dependence of the inelasticity in pp/ppˉpp/p\bar{p} collisions from experimental information on charged particle multiplicity distributions

The dependence of the inelasticity in terms of the center of mass energy is studied in the eikonal formalism, which provides connection between elastic and inelastic channels. Due to the absence of inelasticity experimental datasets, the present analysis is based on experimental information available on the full phase space multiplicity distribution covering a large range of energy, namely 30 $<$ $\sqrt{s}$ $\leq$ 1800 GeV. Our results indicate that the decrease of inelasticity is consequence of minijets production from semihard interactions arising from the scattering of gluons carrying only a very small fractions of the momenta from their parent protons. Alternative methods of estimating the inelasticity are discussed and predictions to the LHC energies are presented

Multiparticle production in the model with antishadowing

We discuss the role of absorbtion and antishadowing in particle production. We reproduce power-like energy behavior of the mean multiplicity in the model with antishadowing and discuss physical implications of such behavior for the hadron structure.Comment: 11 pages, 3 figures, extended version of the talk at the XXXII International Symposium on Multiparticle Dynamics September 7-13, 2002 Alushta, Crimea, Ukrain

Anti-HIV-1 activities of 4 Telomerase Restrictors

MTT Cell Proliferation Assay was used to optimize the concentration of Telomerase Restrictors(TRs) with minimum toxicity to the selected cells. FACSort flow cytometer and Innotest P24 HIV(Human immunodeficiency Virus) antigen mAb ELISA Kit were used to investigate the anti-HIV-1 activities of TRs. The results showed that TRs had low cytotoxicity to the PBMC (Peripheral Blood mononuclear cells) and CEM/GFP if the concentration of TRs was at 50 \u3bcmol/L or below, and the supernatant from PBMC pretreated with SHIV and TR1-001 /TR1-002 could not infect the PBMC, while can infect the C8166 with reduced infectivity, which suggested that the TRs may be one of the novel resources for screening anti-HIV-1 agents

Telomerase restrictors might be a novel source for screening anti-HIV agents

Objectives: to screen anti-HIV agents from telomerase restrictors(TRs); Method: Selection of the maximum concentration of telomerase restrictor with minimum toxicity by means of MTT proliferation determination, and screening of anti-HIV agents by means of determining CEM-GFP fluorescence with FACS and through INNOTEST P24 HIV Antigen mAb ELISA. Results: Two telomerase restrictors were demonstrated to effectively restrict the proliferation of HIV. Conclusion: Telomerase restrictors(TR) might be the source for screening anti-HIV agents
