1红外光谱法研究古代彩绘蛋白胶料光老化的二级结构变化显示文摘动物胶和蛋清是古代重要彩绘文物蛋白胶结材料,对其光老化蛋白质结构变化的研究与探索彩绘文物病变机理和选择科学保护材料、修复方法密切相关。以维也纳艺术历史博物馆的动物胶(骨胶、兔皮胶、鲟鱼胶)和蛋清为研究对象,利用红外光谱技术,结合酰胺Ⅰ带去卷积和高斯拟合法研究光老化过程中蛋白质二级结构的改变。结果表明,四种胶光老化后仍然具备蛋白质红外光谱的典型吸收特征。但红外吸收峰出现了不同程度的位移,其中蛋清糖苷键明显蓝移。酰胺Ⅰ带去卷积和高斯拟合结果显示,蛋白胶的二级结构占比发生了改变。其中,骨胶α-螺旋结构占比降低22.24%,逐渐解螺旋,无规则卷曲结构占比明显增高(9.76%);兔皮胶和鲟鱼胶α-螺旋结构占比分别降低5.31%,4.15%,前者无规则卷曲增幅最低(6.96%),后者反而减少,推测两者的光老化稳定性高。蛋清α-螺旋占比降低程度最高(44.45%),无规则卷曲占比增幅极大(27.49%),光老化稳定性最差。证实利用红外光谱技术,结合酰胺Ⅰ带去卷积和高斯拟合法研究文物蛋白胶料二级结构变化的方法是可行的,但其转化机理还需后期进一步探讨。马珍珍 王丽琴 Gabriela Krist Tatjana Bayerova 杨璐 2017光谱学与光谱分析2017,37,9:9
2Multiple haploids, triploids, and tetraploids found in modern-day “living fossil” Ginkgo biloba显示文摘Ginkgo biloba,the last extant representative of a lineage of Mesozoic gymnosperms,is one of the few seed plants with an exceptionally long(~300 Myr)evolutionary history free of genome-wide duplications(polyploidy).Despite this genome conservatism,we have recently found a viable spontaneous tetraploid Ginkgo sapling during routine screening of several plants,demonstrating that natural polyploidy is possible in Ginkgo.Here we provide a much wider flow cytometry survey of ploidy in some European Ginkgo collections,and own seedlings(>2200 individuals and~200 cultivars).We found a surprisingly high level of ploidy variation in modern-day Ginkgo and documented altogether 13 haploid,3 triploid,and 10 tetraploid Ginkgo plants or cultivars,most of them being morphologically distinct from common diploids.Haploids frequently produced polyploid(dihaploid)buds or branches.Tetraploids showed some genome size variation.The surveyed plants provide a unique resource for future Ginkgo research and breeding,and they might be used to accelerate the modern diversification of this nearly extinct plant lineage.PetrŠmarda Lucie Horová Ondřej Knápek Heidi Dieck Martin Dieck Katarína Ražná Pavel Hrubík Laszlo Orlóci Laszlo Papp Kristýna Veselá Pavel Veselý Petr Bureš 2018Horticulture Research2018,5,1:4
3世界家庭医生组织(WONCA)研究论文摘要汇编——居住在“冷点社区”与健康欠佳、享有卫生服务质量欠佳间的关系显示文摘目的患者居住的社区情况与其所享有的卫生服务质量之间的关系尚未完全明确。本研究旨在调查居住在'冷点社区'(经普查证实的低收入、低文化程度以及不享有多种福利的社区)与享有的卫生服务质量间的关系。方法在12个全科诊所中选取152 962例患者进行调查。将患者所住社区(根据普查所得结果)按照全科诊所服务范围进行编码,并根据低收入(收入低于联邦贫困线水平的2倍被认定为低收入)人群比例、低于高中文化人群比例以及社会剥夺指数水平的四分位数进行分类,具有最低收入、低学历人群比例或最高社会剥夺指数的社区被认定为'冷点社区'。采用双变量回归和Logistic回归分析患者所住'冷点社区'情况与患者慢性病患病情况(肥胖、未得到有效控制的糖尿病)、享有的卫生服务情况[肺炎疫苗接种、癌症(结肠癌、宫颈癌、前列腺癌)筛查以及应用阿司匹林防治心血管疾病情况]间的关系。结果各'冷点社区'患者的分布比例不同,最高比例是最低比例的10倍(29.1%比2.6%)。除了应用阿司匹林之外,享受其他卫生服务情况以及慢性病患病情况均受到了'冷点社区'状况的影响。居住在低学历'冷点社区'的患者患有未得到有效控制的糖尿病的比例高于居住在非'冷点社区'的患者(15%比13%,P<0.05)。回归分析表明,与居住在非'冷点社区'的患者相比,居住在贫困'冷点社区'、低学历'冷点社区'、社会剥夺指数高'冷点社区'的患者享有的宫颈癌筛查服务比例稍高,但享有的结肠癌筛查服务比例较低[OR(95%CI)分别为0.88(0.83,0.93)、0.87(0.82,0.92)、0.89(0.83,0.95)]。结论居住在冷点社区的患者拥有较高的慢性病患病率,且其享有的部分筛查服务质量较差。全科医生可应用领域数据来分配资源,主动积极筛查出此类社区中的慢性病患者以及应该享有却未能享受到筛查服务的患者。LIAW W KRIST A H TONG S T 本刊编辑部 2018中国全科医学2018,21,19:3
