Effects of continuous negative pressure water supply on water consumption, growth and development, as well as physiological mechanism and quality of Capsicum annuum L. were investigated in this paper. Meanwhile, the optimal negative pressure water supply conditions for growth of C. annuum L. were screened out to achieve the goals of water conservation, high yield and high quality, thus providing theoretical foundation for its field production. The pot experiment within the greenhouse was utilized; the continuous negative pressure water supply was adopted; the four treatments, artificial watering（CK）, –5 k Pa（T1）, –10 k Pa（T2）, and –15 k Pa（T3） were set; and the daily water consumption, yield, as well as the biomass, nitrate reductase, root activity, vitamin C, capsaicin, and nutrient uptakes of nitrogen（N）, phosphorus（P） and potassium（K） during various stages of its growth were determined. Compared with CK, when the water supply pressure was controlled at –5 to –15 k Pa in the experiment, the total water consumption of C. annuum L. reduced by 53.42 to 67.75%, the total water consumption intensity reduced by 54.29 to 67.14%, and the water use efficiency increased by 12.66 to 124.67%. The N accumulation in a single strain of C. annuum L. from the color turning stage to the red ripe stage increased by 15.99 to 100.55%, respectively, compared with that of CK; the P accumulation increased by 20.47 to 154.00% relative to that of CK, and the K accumulation increased by 64.92 to 144.9% compared with that of CK. Compared with CK, C. annuum L. yield was remarkably improved by 13.79% at T1, and contents of vitamin C, capsaicin as well as carotenoids at all growth stages were enhanced by 13.42–147.01%, 11.54–71.01%, and 41.1–568.06%, respectively. Nitrate reductase activity, root activity and chlorophyll（a＋b） were markedly increased by 335.78–500%, 79.6–140.68% and 114.95–676.19%, respectively, from immature stage to full ripe stage.

作者： gao-wa Aodeng School of Chemistry and Chemical Engineering Inner Mongolia University

A new modification method for glass slides was developed and applied to make ThinPrep Pap smears,in order to increase the adhesion ability of cervical exfoliative cells.3-glycidyloxypropyl trimethoxysilane(gOPS) was coated on the glass slides firstly on the slides,then poly-L-lysine(PLL) was covalently modified onto the above epoxy-terminated slides to form gOPS-PLL double decorated *** modified slides were characterized using X-ray photoelectron spectroscopy(XPS) and atomic force microscopy(AFM).The cell adhesion ability effect was tested and compared with traditional PLL coated slides by fixing the cervical exfoliative cells on the double adorned *** control test was conducted by the bare glass slides *** cell morphology of cervical exfoliative cells adhered on different slides was observed under the microscope after Papanicolaou *** number of cervical exfoliative cells on the unmodified slides,PLL coated slides and gOPS-PLL coated slides was 10307300,32837226 and 41197280(n=12),*** data among the three different modification methods showed significant differences(one-way analysis of variance,ANOVA test,Po0.05).The cell capturing effect of the gOPS-PLL slide was the best among the three different modified *** addition,the gOPS-PLL slide could enhance the uniformity of the adhered cells and be widely applied to the ThinPrep system for cervical carcinoma screening to increase the accuracy rate of diagnosis.

Introduction: COVID-19 was an emerging disease putting all public health systems in countries around the world in a state of emergency. To be able to prevent its spread and morbidity and mortality, several appropriate strategies were necessary, such as vaccination. The latter has been the subject of controversy. The objective of the present study is therefore to evaluate the factors associated with the acceptance of this vaccine within the population of the Kasenga State Health Area. A result which will shed light on future strategies to be put in place for possible new vaccines. Methodology: Is a prospective and analytical cross-sectional study conducted over a period of approximately 1 month from January 5 to February 5, 2024. A survey questionnaire in Kobotoolbox was useful for collecting data. STATA software was very important for us in analyzing the data collected. Results: Prevalence of vaccination against COVID-19 among the population of the Kasenga State Health Area is 37.5% (28.4 - 45.6). The study revealed that reluctance is observed among most of the population for different reasons, including, first and foremost, the deliberate aspect of not wanting to take the vaccine (46.6%) and rumors that this antigen is dangerous and harmful (32.9%). 72.5% of respondents believe that the COVID-19 vaccine is a fabrication, unhealthy and that the disease itself never existed. The study proved that there was a statistical relationship between age (p = 0.001) and adherence to vaccination. And the refusal of respondents to recommend the vaccine to loved ones was a factor associated with non-adherence to vaccination (OR = 7.901, 95% IC [3.028 - 20.615], p = 0.000). Conclusion: Vaccination against COVID-19 was not well accepted by the population of the study site. Raising public awareness and involving community leaders and political-administrative authorities, which has not been done well, would play an important role in the good perception of the disease, of the vaccine

目的分析肝门部胆管癌(HC)组织中微小RNA-98-5p(mir-98-5p)、ALKB同源蛋白1(ALKBH1)表达水平,并探讨其与患者临床病理特征及预后的关系。方法选取2011年6月至2017年6月行根治性手术的96例HC患者癌组织和相对应的癌旁正常组织(≥5 cm)为研究对象。实时荧光定量PCR(qRT-PCR)法检测组织中mir-98-5p、ALKBH1 mRNA表达水平,免疫组织化学法检测组织中ALKBH1表达。用SPSS 25.0对数据进行统计学分析,计量资料以(x±s)表示,行独立样本t检验;计数资料行χ^(2)检验;使用Pearson相关分析HC组织中mir-98-5p与ALKBH1 mRNA表达水平的关系;使用Kaplan-Meier进行生存曲线分析mir-98-5p、ALKBH1与HC患者5年内总生存率的关系。P<0.05为差异有统计学意义。结果与癌旁正常组织相比,HC组织中ALKBH1 mRNA相对表达水平、ALKBH1阳性率较高(P<0.05),mir-98-5p相对表达水平较低(P<0.05);mir-98-5p、ALKBH1与HC患者淋巴结转移、TNM分期相关(P<0.05)。Pearson相关分析显示,HC组织中mir-98-5p与ALKBH1 mRNA表达水平呈负相关(P<0.05)。Kaplan-Meier生存分析显示,mir-98-5p低表达组5年累计生存率为18.8%,低于mir-98-5p高表达组33.3%(P<0.05);ALKBH1阳性组5年累计生存率为14.0%,低于ALKBH1阴性组43.6%(P<0.05)。结论mir-98-5p低表达、ALKBH1高表达与HC患者淋巴结转移、TNM分期及预后相关。

随着光纤制备工艺以及纳米材料制备技术的发展,光纤探针已成为一种新型的表面增强拉曼散射(SERS)基底,通过在普通单模光纤或多模光纤上制备不同的结构并修饰相应的纳米材料,可以得到多种类型的光纤表面增强拉曼散射探针,并实现较好的检测效果。但受限于光纤本身的结构,普通光纤仅能利用端面或侧表面提供拉曼检测的“热点”区域,限制了其SERS性能的进一步提高。因此制备了大孔柚子型微结构光纤(MSF)表面增强拉曼散射(SERS)探针,其中大孔柚子型MSF SERS探针结构通过一段阶跃多模光纤与柚子型微结构光纤熔接制得。实验分别对自制的纳米银溶胶基底以及大孔柚子型MSF SERS探针的SERS性能进行检测。采用溶胶自组装法制备负载银纳米颗粒的MSF SERS探针,通过控制自组装时间制备不同光纤SERS探针(Ag/MSF-x,其中x为自组装时间,分别为15、30、45、60 min)。采用溶液检测方法,利用Ag/MSF-x探针对10^(-3) mol·L^(-1)的亚甲基蓝(MB)探针分子进行检测,通过比较相同条件下的增强效果筛选得到Ag/MSF-45探针。为进一步检测Ag/MSF-45探针的SERS性能,制备不同浓度的MB溶液,分别利用纳米银溶胶基底和Ag/MSF-45探针对其进行检测。实验结果表明,纳米银溶胶基底对MB的检测限(LOD)为10^(-6) mol·L^(-1),Ag/MSF-45探针对MB的检测限(LOD)为10^(-7) mol·L^(-1);拉曼信号的再现性结果表明纳米银溶胶基底以及Ag/MSF-45探针在各个特征峰处的RSD值均在合理范围内;在1619 cm^(-1)拉曼位移处对纳米银溶胶基底以及Ag/MSF-45探针检测MB的拉曼强度和浓度进行对数转换拟合,纳米银溶胶基底的拟合优度R2达0.91628,Ag/MSF-45探针的拟合优度R2达0.98848;纳米银溶胶基底和Ag/MSF-45探针的再现性结果表明,其在各个特征峰处的RSD值均处于合理范围,但Ag/MSF-45探针的各特征峰RSD值均小于纳米银溶胶基底,最大为13.89%;利用10^(-6) mol·L^(-1)的MB对Ag/MSF-45探针的增强因子(AEF)进行计算,Ag/MSF-45探针的AEF达到6.09×10^(6),表现出良好的增强效果。因此,基于大孔柚子型MSF SERS探针凭借独特的空气孔结构使其具有较高的灵敏度以及良好的再现性,且其SERS性能均优于纳米银溶胶基底,在农业、化学分析、生物检测等领域及大分子物质检测等方面应用前景广泛。

采用水提醇沉法提取刺玫根粗多糖,以Sevage法和TCA法脱蛋白,进一步分级醇沉法分离纯化得到较纯的60%醇沉物(RDRP)进行结构鉴定和活性评价。苯酚浓硫酸法测定出刺玫根多糖RDRP总糖含量为94.1%;高效凝胶渗透色谱法测定表明主要含有重均分子量为13.1 kDa,相对分散度为1.2的多糖;通过高效离子色谱法和红外光谱测定,鉴定刺玫根多糖为由葡萄糖、阿拉伯糖、半乳糖、甘露糖、木糖等5种单糖组成的含有α-构型的中性吡喃多糖。环磷酰胺诱导的免疫抑制小鼠模型实验结果表明,与模型组相比,刺玫根多糖各剂量组小鼠的脾脏和胸腺指数明显升高(Pgg、IgM、IgA以及细胞因子TNF-α、IFN-γ、IL-6与IL-2的分泌水平,结果显示,与模型组比较,刺玫根多糖组显著上调小鼠血清中免疫球蛋白IgA、Igg、IgM浓度水平(P<0.01)及IL-2、IFN-γ、TNF-α、IL-6的含量(P<0.01);Western blot法测定各组TLR4、MyD88、TRAF-6和NF-κB p65蛋白的表达水平,发现刺玫根多糖各剂量组脾脏中TLR4、TRAF-6蛋白极显著上升(P<0.01),高剂量组的MyD88蛋白极显著上升(P<0.01),其他组呈现上升趋势;刺玫根多糖各剂量组NF-κB p65蛋白均有上升趋势,因此其免疫调节作用机制可能与TLR/NF-κB通道有关。本研究初步阐明刺玫根多糖的基本结构特征和其免疫调节作用及其机制,为刺玫根多糖的开发应用提供一定价值的实验依据。

为防治澳大利亚主要仓储害虫,开发富氮气调技术作为熏蒸剂的辅助手段。然而,由于成本问题,一直影响其在行业推广应用。本研究利用中国长顺安达公司的先进膜分离技术,与传统的制氮技术(变压吸附/PSA)进行性能比较,在西澳Kwinana的CBH粮食港,开展实仓应用实验,以解决阻碍其推广的运营和成本问题。为满足澳大利亚严格的标准操作条件,长顺安达专业团队对港口设备进行了升级改造,目标消杀成本设定为0.50澳元/吨粮(磷化氢的高端熏蒸成本)。研究表明,旧的PSA技术的运营成本为2.43澳元/吨粮,该技术在产生和维持控制害虫所需的99%氮气浓度水平方面也显示出操作局限性。相比之下,使用膜技术制氮的成本为0.99澳元/吨粮,其他性能增益还包括运行4.5天内即可产生所需的氮气浓度,且可维持14天以完全控制害虫。
