1用PCR-RFLP技术鉴别嗜人按蚊和中华按蚊的研究显示文摘目的 依据嗜人按蚊和中华按蚊rDNA的ITS2区段基因特征 ,建立一种新的嗜人按蚊和中华按蚊基因鉴别技术。方法 对不同地区的嗜人按蚊、可疑嗜人按蚊和中华按蚊样本通过采用特异性ITS2 引物PCR扩增 ,限制性内切酶RsaI和HinfI消化 ,以及琼脂糖凝胶电泳分析进行PCR -RFLP基因鉴别。 结果 不同地区嗜人按蚊rDNA的ITS2 基因PCR扩增产物能被限制性内切酶HinfI酶切 ,并显示一条 4 5 0bp的酶切DNA条带 ;中华按蚊的ITS2 基因PCR扩增产物则能被限制性内切酶RsaI酶切 ,并显示 4 0 0bp和 2 0 0bp两条酶切DNA条带 ;辽宁可疑嗜人按蚊的PCR -RFLP结果与嗜人按蚊相同而广东珠海可疑嗜人按蚊的PCR -RFLP结果与中华按蚊相同。结论 依据rDNA的ITS2 区段基因特征建立的PCR -RFLP技术可用于嗜人按蚊和中华按蚊的基因鉴别。采用该PCR -RFLP基因鉴别技术发现辽宁可疑嗜人按蚊的基因与中国大陆的嗜人按蚊属同种 ,而广东可疑嗜人按蚊的基因与中华按蚊属同种。高琪 R D Cooper 周华云 潘波 杨文 郭传坤 黄光全 李凤华 李菊林 沈宝祥 Qin Cheng 2002中国人兽共患病杂志2002,18,6:15
2Nat Genet:单基因突变导致过敏性皮炎的发生显示文摘最近,研究者们鉴定出了一类导致神经性皮炎发生的关键基因突变:CARDll。来自美国NIH过敏与传染病研究所的研究者们通过对四个没有血缘关系的患病家庭进行分析,发现了这一导致疾病产生的基因、Chi A Ma, Yuan Zhang, Michael A Weinreich, Jonathan J Lyons, Celeste G Nelson, Thomas DiMaggio, Kelly D Stone, Joshua D Milner Jeffrey R Stinson, Elisa Ruffo, Batsukh Dorjbal, Swadhinya Arjunaraja, Kelsey Voss, Andrew L Snow Jordan K Abbott, Pia J Hauk, Paul R Reynolds, Erwin W Gelfand Elisa Ruffo Salomé Glauzy, Natsuko Yamakawa, Eric Meffre Jennifer Stoddard, Julie Niemela, Sergio D Rosenzweig Yu Zhang, Helen F Matthews Joshua J McElwee Nina Jones Alejandro Palma, Matías Oleastro, Emma Prieto, Andrea R Bernasconi, Geronimo Dubra, Silvia Danielian, Jonathan Zaiat, Marcelo A Marti Brian Kim Megan A Cooper Neil Romberg 2017现代生物医学进展2017,17,27:3
3Euler Deconvolution with Improved Accuracy and Multiple Different Structural Indices显示文摘Euler deconvolution is a semi-automatic interpretation method that is frequently used with magnetic and gravity data. For a given source type, which is specified by its structural index (SI), it provides an estimate of the source location. It is demonstrated here that by computing the solution space of individual data points and selecting common source locations the accuracy of the result can be improved. Furthermore, only a slight modification of the method is necessary to allow solutions for any number of different SIs to be obtained simultaneously. The method is applicable to both evenly and unevenly sampled geophysical data and is demonstrated on gravity and magnetic data.

8牙本质胞外基质对人血管内皮细胞增殖的影响显示文摘目的 :探讨牙本质胞外基质成分 (dentineextracellularmatrixcomponents,DM)对血管内皮细胞增殖的影响。方法 :用 10 0 g/LEDTA ,在pH 7.2和蛋白酶抑制剂存在的条件下 ,从健康人牙中提取DM。第 3代人脐静脉内皮细胞 (humanumbilicalveinendothelialcell,HUVEC) ,在含有不同浓度DM培养液中培养 8d ,每 2天计数 1次 ,绘制生长曲线。并对第 8天对照 (不含DM培养 )与实验组的细胞数进行Mann -Whitney统计分析。结果 :HUVEC在DM浓度为 0 .0 0 0 1、0 .0 0 1和 0 .0 1mg/mL的培养液中培养时较对照分别增长了 4 9% (P =0 .0 0 0 6 )、2 1%和 9% ,在DM浓度为 0 .1和 1mg/mL时 ,减少 2 2 %和 74 % (P =0 .0 0 0 3)。 结论 :DM对血管内皮细胞增殖具有计量依赖型影响效应。低浓度DM可刺激内皮细胞的增殖 ,而高浓度DM则可抑制该细胞的增殖。提示 :这一计量依赖型效应可能正是牙髓损伤后造成局部不同的血管形成方式 ,并最终导致不同修复结果的原因。张蓉 Gay Smith Alastair J Sloan Paul R Cooper 赵守亮 Athony J Smith 2004牙体牙髓牙周病学杂志2004,14,6:2
