1电感耦合等离子体质谱分析在中国古陶瓷研究中的应用显示文摘用电感耦合等离子体质谱法(ICP-MS)测试了宋元时期磁州窑、吉州窑、龙泉务窑瓷胎的39种微量元素, 以探索这种在中国科技考古中尚极少使用的方法的应用前景. 发现微量元素特征明确反映了3个瓷窑不同种类的瓷胎原料及其矿物组成, 可将其产品明确区分. 磁州窑元代与宋金样品之间、龙泉务窑粗细两组瓷器之间的元素特征也明显不同. 磁州窑中优质仿定窑瓷器的元素特征迥异于普通产品, 说明仿定瓷胎使用了特别的原料, 并有可能在使用前进行了高于普通磁州窑瓷器的精细加工. 发现不同瓷窑以及同一瓷窑内不同类型瓷器之间元素特征的差别, 可以用元素地球化学原理进行合理的解释. ICP-MS可测试40多种微量元素, 元素分布范围广泛, 提供的信息量大, 多数元素的分析误差在2%以下, 可有效运用于中国古陶瓷研究.李宝平 赵建新 Kenneth D.Collerson Alan Greig 2003科学通报2003,48,7:10

4On the origin of microbial magnetoreception显示文摘A broad range of organisms;from prokaryotes to higher animals;have the ability to sense and utilize Earth's geomagnetic field-a behavior known as magnetoreception.Although our knowledge of the physiological mechanisms of magnetoreception has increased substantially over recent decades;the origin of this behavior remains a fundamental question in evolutionary biology.Despite this;there is growing evidence that magnetic iron mineral biosynthesis by prokaryotes may represent the earliest form ofbiogenic magnetic sensors on Earth.Here,we integrate new data from microbiology;geology and nanotechnology,and propose that initial biomineralization of intracellular iron nanoparticles in early life evolved as a mechanism for mitigating the toxicity of reactive oxygen species(ROS),as ultraviolet radiation and free-iron-generated ROS would have been a major environmental challenge for life on early Earth.This iron-based system could have later been co-opted as a magnetic sensor for magnetoreception in microorganisms;suggesting an origin of microbial magnetoreception as the result of the evolutionary process of exaptation.Wei Lin Joseph L.Kirschvink Greig A.Paterson Dennis A.Bazylinski Yongxin Pan 2020National Science Review2020,7,2:4

6Optimal length of triple therapy for H pylori eradication in a population with high prevalence of infection in Chile显示文摘AIM:To compare the efficacy of 7-d versus 14-d triple therapy for the treatment of H pylori infection in Chile,with a prevalence of 73% in general population. METHODS:H pylori-infected patients diagnosed by rapid urease test,with non-ulcer dyspepsia or peptic ulcer disease were randomized to receive omeprazole 20 mg bid,amoxicillin 1 g bid,and clarithromycin 500 mg bid for 7 (OAC7) or 14 (OAC14) d. Primary outcome was eradication rate 6 wk after the treatment. Subgroup analysis was carried out considering the eradication rate among patients with or without peptic ulcer disease and eradication rate among smokers or non-smokers. RESULTS:One hundred and thirty-one patients were randomized to OAC7 (n = 69) or OAC14 (n = 62). The overall eradication rate (intention-to-treat) was 78.3% in OAC7 and 85.5% in OAC14 groups,without a significant difference (P =0.37). No significant difference in the eradication rate was found among the patients with peptic ulcer disease (n = 31) between the OAC7 group (85.7%) and OAC14 group (87.5%). However,smokers had an obviously lower eradication rate compared to non-smokers,particularly in the OAC7 group (57.1% in smokers vs 83.6% in non-smokers; P = 0.06). Adverse effects rate were similar between both groups. CONCLUSION:Short-term efficacy of triple therapy with OAC for 7 d is comparable to 14 d in this high-prevalence population. Longer follow-up,and studies focused to some subgroups of patients (smokers and non-ulcerpatients) are necessary to support widespread use of 7-d instead of 10-14-d triple therapy in a developing country like Chile.Arnoldo Riquelme Alejandro Soza Cesar Pedreros Andrea Bustamante Felipe Valenzuela Francisco Otarola Eduardo Abbott Marco Arellano Brenda Medina Alejandro Pattillo Douglas Greig Marco Arrese Antonio Rollan 2007World Journal of Gastroenterology2007,13,21:3
