1不同氮源对海洋微藻氮同位素分馏作用的影响显示文摘以海链藻 (Thalassiosirapseudonana)为研究对象 ,分别考察了以硝酸盐、铵盐和尿素为氮源的氮同位素分馏作用。在建立相应理论模型基础上 ,分别计算出各个实验体系的ε值。结果表明 ,在藻类生长初期 ,δ1 5N均较低 ,其δ1 5N的积累主要发生在指数增长期 ,在稳定期达到最高 ,与氮源的初始δ1 5N相同 ;不同氮源的氮同位素分馏作用也不相同 ,其中以铵盐最强 ,硝酸盐次之 ,尿素最弱。考虑到实际情况下氮化合物并非单一存在 ,作者还进一步考察了上述3种氮源混合后对其同位素分馏作用的影响 ,发现混合氮源体系的表观ε值介于单一氮源时的最大与最小ε值之间 ,该结果较好地解释了Montoya等 ( 1 991 )在Chesapeak湾的现场实验结果。俞志明 Waser N A D Harrison P J 2004海洋与湖沼2004,35,6:13
2Mapping QTL associated with Verticillium dahliae resistance in the cultivated strawberry(Fragaria×ananassa)显示文摘A biparental cross of octoploid strawberry segregating for resistance to Verticillium dahliae,the causative agent of Verticillium wilt,was screened under field conditions for three seasons.Average wilt scores were significantly associated with multiple QTL,which were mostly significant across all years.Markers significantly associated with the traits were used to screen material with known wilt resistance and susceptibility phenotypes.A clear and statistically significant relationship was observed between resistant,tolerant and susceptible material and the total number of markers present in the different resistance classes.In field situations resistance QTL appear to behave in an additive manner.These markers are abundant in the cultivated strawberry germplasm indicating that,despite the large number of markers,clear genetic gain is possible through marker-assisted breeding.L Antanaviciute NŠurbanovski N Harrison K J McLeary D W Simpson F Wilson D J Sargent R J Harrison 2015Horticulture Research2015,2,1:5
3化学气体污染突发事件中的人群疏散:横断面调查显示文摘目的比较一个塑料工厂发生化学事故后躲藏和被疏散人群的健康结局。设计横断面调查。背景英格兰西南的市区。研究对象该地区1750位曾暴露于化学烟雾的居民,其中472人被疏散,剩下的1278人被建议躲藏在室内。主要结局测定不利于健康的症状数目。出现4个或以上症状者被确定为一个病例。主要的结果1096位居民(63%;299人被疏散,797人躲藏起来)为本分析提供了资料。被疏散人群的平均症状分值和病例的比例比躲藏人群的要高(疏散者:症状分值1.9,病例比例19.7%(n=59);躲藏者:症状分值1.0,病例比例9.5%(n=76),二者比较P<0.001)。在事故发生后两周末时二组间的差异明显变小。成为病例的两个主要可变更危险因子是疏散(比值比2.5,95%可信区间1.7~3.8)和在事故当天直接暴露于烟雾的时间超过2小时(比值比2.0,95%可信区间1.7~2.3)。住所距工厂的距离或是干预前(头6个小时)暴露的水平对于研究对象成为病例的作用不大。结论在此次化学事故中躲藏起来可能是优于疏散人群的保护措施。这与专家们普遍认为的观点一致。尽管本研究有一定的局限性,但它是基于一场真实的事件。疏散本身有一定的风险和资源上的限制,认识上的增加可能会有助于减少将来不必要的疏散。S Kinra G Lewendon R Nelder N Herriott R Mohan M Hort S Harrison V Murray 陈雷(译) 2005英国医学杂志中文版2005,8,5:3
4重组脊髓灰质炎病毒用于治疗复发胶质母细胞瘤(英文)显示文摘Background The prognosis of patients with recurrent World Health Organization(WHO)grade IV malignant glioma is dismal,and there is currently no effective therapy.We conducted a dose-finding and toxicity study in this population of patients,evaluating convection-enhanced,intratumoral delivery of the recombinant nonpathogenic polio-rhinovirus chimera(PVSRIPO).PVSRIPO recognizes the poliovirus receptor CD155,which is widely expressed in neoplastic cells of solid tumors and in major components of the tumor microenvironment.Methods We enrolled consecutive adult patients who had recurrent supratentorial WHO grade IV malignant glioma,confirmed on histopathological testing,with measurable disease(contrast-enhancing tumor of≥1 cm and≤5.5 cm in the greatest dimension).The study evaluated seven doses,ranging between 107 and 1010 50%tissue-culture infectious doses(TCID50),first in a dose-escalation phase and then in a dose-expansion phase.Results From May 2012 through May 2017,a total of 61 patients were enrolled and received a dose of PVSRIPO.Dose level-1(5.0×107TCID50)was identified as the phase 2 dose.One dose-limiting toxic effect was observed;a patient in whom dose level 5(1010TCID50)was administered had a grade 4 intracranial hemorrhage immediately after the catheter was removed.To mitigate locoregional inflammation of the infused tumor with prolonged glucocorticoid use,dose level 5 was deescalated to reach the phase 2 dose.In the dose-expansion phase,19%of the patients had a PVSRIPO-related adverse event of grade 3 or higher.Overall survival among the patients who received PVSRIPO reached a plateau of 21%(95%confidence interval,11 to 33)at 24 months that was sustained at 36 months.Conclusions Intratumoral infusion of PVSRIPO in patients with recurrent WHO grade IV malignant glioma confirmed the absence of neurovirulent potential.The survival rate among patients who receivedPVSRIPO immunotherapy was higher at 24 and 36 months than the rate among historical controls.Desjardins A Gromeier M Herndon JE 2nd Beaubier N Bolognesi DP Friedman AH Friedman HS McSherry F Muscat AM Nair S Peters KB Randazzo D Sampson JH Vlahovic G Harrison WT McLendon RE Ashley D Bigner DD 2018中华神经外科疾病研究杂志2018,17,4:2
