Design and Implementation of VIP Consumption Information Management System for Large and Medium Supermarket [PDF]

open access: yes, 2016
经济全球化使得零售业得到了非常快速的发展,各种零售商日渐增多,但蒸蒸日上的背后,零售商面临的竞争压力也越来越大:在经济结构调整和外部需求疲软的影响下,中国的经济增长是低的;收入增长放缓,消费的意愿一般不会强;传统的零售商同质化,竞争越来越激烈。同时,随着信息技术的日趋进步和普及,特别网络技术的普及,电子商务的普及作为商业交易的前沿领域,传统零售的观念和行为产生了巨大的影响和冲击。 在此背景下,借助信息技术,维护客户满意度、提高客户忠诚度,规模优势和市场优势转化成效益和盈利能力 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

强直性脊柱炎患者TNF-α基因启动子区甲基化状态的初步研究

open access: yesZhongguo shiyan zhenduanxue, 2014
目的探讨强直性脊柱炎(AS)患者肿瘤坏死因子α(TNF-α)基因启动子区甲基化状态与其表达量增高及发病机制的关系。方法采用甲基化特异性PCR技术(MS-PCR)和重亚硫酸盐转化基因测序法(BSP)。结果 MSP结果表明AS患者与健康体检者TNF-α基因启动子区的M引物和U引物均出现条带,提示扩增区域在病例组与健康组间呈现一种甲基化与未甲基化并存的状态,两组之间并无差异。进一步应用BSP法,结果显示AS病例组平均甲基化率为29.17%,健康对照组平均甲基化率为32.67%,χ2=0.941(P>0.05),

液相色谱-质谱联用技术筛查synemin蛋白及其在肾癌诊断中的作用

open access: yesZhongguo shiyan zhenduanxue, 2020
目的本研究的目的是利用化学和生物信息学的方法寻找肾癌和癌旁组织的差异蛋白,探讨目标蛋白作为肾癌生物标志物的可能性。方法采用液相色谱-质谱法鉴定肾癌和癌旁组织差异表达的蛋白,借助免疫组织化学的方法观察肾癌和癌旁组织标本中synemin蛋白的表达。结果肾癌与癌旁组织差异表达的蛋白有26个,肾癌组织中过表达18个,低表达8个。synemin蛋白在肾癌组织中的高表达,统计学差异明显 ...

损伤肌肉中超氧化物歧化酶活性及丙二醛含量变化

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1995
本研究在大鼠的肌肉损伤模型上,探讨测定超氧化物歧化酶(SOD)、丙二醛(MDA)含量的变化,推断生前、死后损伤的可能性。结果显示:生前实验组伤侧肌肉的SOD活性与对照侧肌肉相比明显减少,有显著性差异(P<0.01),MDA的含量与对照侧肌肉相比明显增加,有显著性差异(p<0.01);死后实验组伤侧肌肉的SOD活性、MDA含量与对照侧肌肉相比无显著性差异(P>0.05)。生前损伤组SOD活性、MDA含量的差值与正常组和死后损伤组相比,有显著性差异(P<0.01);正常组SOD活性 ...
