白血病化疗后免疫抑制所致感染后炎症因子表达对感染原研判的价值探讨
Zhongguo shiyan zhenduanxue, 2022 目的 研究白血病患者化疗后免疫抑制所致感染后炎症因子表达对感染原研判的价值。方法 回顾性分析我院自2018年1月-2020年12月收治的白血病化疗患者120例进行研究。将其按照化疗后是否合并感染分成感染组77例与非感染组43例。比较两组血清PCT、CRP、IL-6水平以及基线资料。此外，将感染组按照病原菌差异分成细菌感染组53例与真菌感染组24例。比较两组血清PCT、CRP、IL-6水平。并对白血病患者化疗后免疫抑制所致感染进行多因素Logistic回归分析。结果 感染组血清PCT、CRP、IL ...

リコンビナント水痘生ワクチンによるB 型肝炎の予防 [PDF]
, 1991 水痘帯状疱疹ウイルス感染は， 初感染で水痘を発症し宿主は回復するが， ウイルスは神経節に潜伏し，加齢・免疫の低下に伴い帯状疱疹を引き起こす。水痘ウイルスの潜伏期はほぼ14 日で， 感染した場合その95%が発症するとされている。水痘感染は， 免疫不全状態においては， 致命的となることが知られており， 特に小児白血病では， 7 -28% の死亡率が報告されている。また健康小児・成人においても肺炎・脳炎などの重篤な合併症を起こす。小児科領域では， その感染伝播力の強さのため病棟内で患者がでた場合 ...

Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Engineering the Plasmodium berghei genome via CRISPR/Cas9 system [PDF]
, 2015 疟疾是由雌性按蚊叮咬而感染疟原虫所引起的虫媒传染病。2013年全球因感染疟疾而死亡的人数达58万，是世界公共卫生的沉重负担，主要易感人群是撒哈拉沙漠以南非洲地区5岁以下免疫力低下的儿童。其中感染恶性疟原虫引起的重症脑型疟最为严重且致死率极高。啮齿动物疟原虫是研究疟原虫与宿主互作的良好模型，伯氏疟原虫ANKA株系（PlasmodiumbergheiANKA）感染小鼠能够产生实验型脑疟症状，已广泛用于恶性疟原虫的致病机理研究。虽然疟原虫的转染技术有二十年的历史了，但由于缺乏高效的基因修饰工具 ...

Appraisal of the Sri Lanka Dairy Sector volume 2: Main report [PDF]
, 2010 从蛙虹彩病毒（Rana grylio virus,RGV）中克隆出一个虹彩病毒科的序列保守基因RGV-12L,序列分析表明该基因全长894 bp,编码一个含297个氨基酸的多肽,分子量为33 kD。构建包含该基因全长的原核表达载体,进行原核表达,获得了分子量约53 kD的融合蛋白。将融合蛋白经腹腔注射免疫小鼠,制备出鼠抗RGV-12L血清。通过RT-PCR和Western blotting分析RGV感染细胞后RGV-12L的转录时序,感染4h可以在RNA水平检测到RGV-12L的转录 ...
