    Notes: Abstract. The energy-loss effect in nuclear matter is another nuclear effect apart from the nuclear effects on the parton distribution as in deep inelastic scattering process. The quark energy loss can be measured best by the nuclear dependence of the high energy nuclear Drell-Yan process. By means of two typical kinds of quark energy-loss parametrization and the different sets of nuclear parton distribution functions, we present an analysis of the E866 experiments on the nuclear dependence of Drell-Yan lepton pair production resulting from the bombardment of Be, Fe and W targets by 800 GeV protons at Fermilab. It is found that the quark energy loss in cold nuclei is strongly dependent on the used nuclear parton distribution functions. The further prospects of using relatively low energy protons incident on nuclear targets are presented by combining the quark energy-loss rate determined from a fit to the E866 nuclear-dependent ratios versus x 1, with the nuclear parton distribution functions given from lA deep inelastic scattering (DIS) data. The experimental study of the relatively low energy nuclear Drell-Yan process can give valuable insight in the energy loss of the fast quark propagating through cold nuclei and help to pin down nuclear parton distribution functions.

    Notes: Quarantine regulations require domestic cherries exported to Japan be treated to control for codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae). The current procedure, methyl bromide fumigation, uses a restricted chemical, reduces fruit quality, and involves health, safety and environmental concerns. Single and double hot water dips were evaluated using fresh ‘Bing’ and ‘Sweetheart’ sweet cherries from Washington state as a potential replacement. The double dip procedure had a pretreatment bath at 40C for 5 min. For both procedures, submersions in heated water from 48 to 55C for 2–14 min were examined for treatment efficacy against third-instar codling moth and fruit quality. Although a 100% mortality response was found for each temperature and procedure, the submersion durations significantly damaged fruit and stem parameters for both cultivars. Thus, hot water dips are not feasible for Pacific Northwest cherries at this time.

    Notes: Background Histo-blood groups, ABO, Lewis (Le) and secretor (Se) were found to be associated with lower lung function and wheezing in coal miners as well as in asthmatic children in some studies but not others, possibly reflecting the genetic heterogeneity among different ethnicities and local environmental exposure.Objective The present study was conducted to determine the association between ABO, Lewis and secretor genetic complex with susceptibility of childhood asthma in Taiwan.Methods We randomly selected 136 asthmatic children and 161 age-matched controls from a childhood asthma survey conducted in primary schools. ABO and Lewis blood groups were determined by red blood cell agglutination methods. Analysis of Se genotype was performed by PCR with sequence-specific primers.Results There was a higher prevalence rate in secretor subjects (Se/Se) (odds ratio (OR)=1.7, confidence interval (CI)=1.022–2.938) in asthma as compared with controls. The combined effect of these three blood systems revealed that blood group O/secretor phenotype (Se/Se) (OR=2.7, CI=1.126–6.033), and blood group O/Le(a−b−) (OR=3.6, CI=1.080–11.963, P〈0.03) individuals were significantly associated with asthma. The Lewis Le(a−b−) recessive genotype (OR=3.3, CI=1.267–8.482), or the joint blood group O/Le(a−b−) phenotype (OR=5.2, CI=1.259–21.429, P〈0.02), was significantly associated with high serum IgE (〉500 IU), respectively. There was no association of these three blood systems with the sensitivity of dust mite, Dermatophagoide pteronyssinus, in our study population.Conclusions We concluded that blood group O/secretors (Se/Se) and O/Le(a−b−) were associated with childhood asthma, and may act as one of the predominant factors for environmental triggers of allergy for asthmatic children in Taiwan.

    Notes: Colon cancer (CC) is one of the most common malignancies in the Western world. Although surgical resection is the first choice worldwide, at this point an effective approach for the treatment of patients with metastasis and cancer recurrence post-operation has not yet been found. The aim of this study was to investigate the role of the allogeneic dendritomas from fusion of dendritic cells (DC) and metastatic CC cells in the activation of anti-tumour immunity against metastatic CC. Dendritomas were generated by fused allogeneic human peripheral blood DC with metastatic CC cells using 50% polyethylene glycol. The proliferation of the T cells and the toxicity of the cytotoxic T lymphocytes were observed after T cell pulsed with allogeneic dendritomas. The activated ratios of CD4+T helper 1 and CD8+Tc1 cells were about 51.55 and 65.60% after T cells were mixed with fusions for 24 h, which higher than those of controls. The proliferation of T cells were significantly higher than those of control after T cell pulsed with dendritomas (P 〈 0.01). Significantly, the activated CD8+ T lymphocytes effectively lysed the CC cells. These results demonstrate that allogeneic dendritomas activate T-cell responses against metastatic CC cells.
