| 1 | 一种干红葡萄酒的光谱指纹图谱分析方法(英文)显示文摘采用数据可视化技术开发一种干红葡萄酒的光谱指纹图谱,用于不同类别干红葡萄酒的鉴别。实验采集我国河北沙城和昌黎两个产区的干红葡萄酒样品,酒样在酿造年份、品种和陈酿方式上有差异。葡萄酒样品经反相C18柱分馏得到9个馏分,低压旋转浓缩至干后,再用与分馏样品等量的模拟酒溶解。随后,葡萄酒及其分馏样品经UV-Visible分析,收集190~1 100nm波段的光谱吸收值,利用可视化技术处理数据得到供试酒样的光谱指纹图谱。最后,采用高效液相色谱-二极管阵列检测器(HPLC-DAD),在指纹图谱差异明显的波段选择检测波长,定性分析葡萄酒和馏分中的单体酚及其衍生物。结果显示,供试干红葡萄酒样品光谱特征的差异在190~600nm。不同品种干红葡萄酒的光谱数据可视化结果差异不大,但不同年份酒样有明显的区别,主要集中在520nm的波段,不同产地葡萄酒的差异主要体现在F8馏分上,不同陈酿方式葡萄酒的可视化特征几乎涵盖整个可视化波段。HPLC-DAD在280,313,365和520nm波长下定性分析结果揭示了对光谱指纹图谱的特征有影响的单体酚及其衍生物。研究结果表明,采用可视化技术设计的葡萄酒光谱指纹图谱可以区分不同年份、产地和陈酿方式的干红葡萄酒产品。 | 文彦 陶永胜 侯小凡 Marta Dizy | 2014 | 光谱学与光谱分析2014，34，1： | 3 |

| 9 | Epidemic management in a measles outbreak in 2023,the return of vaccine-preventable diseases:A single center,retrospective observational study显示文摘Objective:To investigate the importance of immunization in preventing measles infection and to determine the most useful laboratory tests for confirmation of measles.Methods:This study included pediatric cases evaluated with a presumed diagnosis of measles between December 2022 and June 2023,at Marmara University Pendik Training and Research Hospital.The effects of vaccination status and underlying disease on the clinical course,treatments,and complications were evaluated.Results:In total,117 patients were enrolled in the study with a median age of 80 months(IQR:32.5-125.0).Twelve patients with contact history were asymptomatic and had an underlying disorder,and intravenous immunoglobulin was given to them for post-exposure prophylaxis.Fifty-one patients had confirmed measles diagnosis.Ribavirin treatment was given to three patients(a newborn,a girl with rhabdomyosarcoma,and a healthy boy)with respiratory distress.Seventy-eight percent of confirmed measles cases were unvaccinated,and all hospitalized cases were unvaccinated or under-vaccinated.Four full-vaccinated children had confirmed measles infection.Measles PCR from nasopharyngeal swabs was negative in all of them,and their diagnosis was established with anti-measles IgM positivity.Conclusions:The measles vaccine is the most effective way to protect from measles and measles-related complications.Although measles can also occur in fully vaccinated patients,the disease is milder than in unvaccinated patients.Using ELISA and RT-PCR tests together may be beneficial in patients with high clinical suspicion for early diagnosis. | Sevgi Aslan Tuncay Gulsen Akkoc Seyhan Yilmaz Burcu Parlak Pinar Canizci Erdemli Aylin Dizi Isik Didem Buyuktas Aytac Meryem Cagla Abaci Capar Eda Kepenekli Kadayifci | 2024 | Asian Pacific Journal of Tropical Medicine2024，17，3： | 0 |
