Pancreatic tuberculosis masquerading as pancreatic serous cystadenoma

引用

World Journal of Gastroenterology 2009年第8期15卷 1010-1013页

作者： Seung Goun Hong jae Seon Kim Moon Kyung Joo Kwang gyun Lee Key Hyeon Kim Cho Rong Oh Jong-jae Park Young-Tae Bak Department of Internal Medicine Korea University College of Medicine Seoul South Korea

Solitary pancreatic involvement of tuberculosis is rare, especially in an immunocompetent individual, and it may be misdiagnosed as pancreatic cystic neoplasms. Pancreatic cystic neoplasms are being identified in increasing numbers, probably because of the frequent use of radiology and advances in endoscopic techniques. However, they are composed of a variety of neoplasms with a wide range of malignant potential, and it is often difficult to differentiate pancreatic tuberculosis mimicking cystic neoplasms from benign or malignant pancreatic cystic neoplasms. Non-surgical diagnosis of pancreatic tuberculosis is inconclusive and continues to be a challenge in many cases. If so, then laparotomy should be employed to establish the diagnosis. Therefore, pancreatic tuberculosis should be kept in mind during the differential diagnosis of solitary cystic masses in the pancreas. We report a patient who had solitary pancreatic tuberculosis masquerading as pancreatic serous cystadenoma.

Preliminary Results of the Ground-Based Orographic Snow Enhancement Experiment for the Easterly Cold Fog (Cloud) at Daegwallyeong during the 2006 Winter

Advances in Atmospheric Sciences 2009年第2期26卷 222-228页

作者： Myoung-Joo LEE Ki-Ho CHANG gyun-Myoung PARK Jin-Yim JEONG Ha-Young YANG Ki-Deok JEONG Joo-Wan CHA Sung-Soo YUM jae-Cheol NAM Kyungsik KIM byung-Chul CHOI National Institute of Meteorological Research Korea Meteorological Administration Department of Atmospheric Sciences Yonsei University Department of Physics Pukyong National University

The snow enhancement experiments, carried out by injecting AgI and water vapor into orographically enhanced clouds （fog）, have been conducted to confirm Li and Pitter＇s forced condensation process in a natural situation. Nine ground-based experiments have been conducted at Daegwallyeong in the Taebaek Mountains for the easterly foggy days from January-February 2006. We then obtained the optimized conditions for the Daegwallyeong region as follows： the small seeding rate （1.04 g min-1） of AgI for the easterly cold fog with the high humidity of Gangneung. Additional experiments are needed to statistically estimate the snowfall increment caused by the small AgI seeding into the orographical fog （cloud） over the Taeback Mountains.

A new heuristic approach was undertaken for the establishment of a core set for the diversity research of rice. As a result, 107 entries were selected from the 10 368 characterized accessions. The core set derived using this new approach provided a good representation of the characterized accessions present in the entire collection. No significant differences for the mean, range, standard deviation and coefficient of variation of each trait were observed between the core and existing collections. We also compared the diversity of core sets established using this Heuristic Core Collection （HCC） approach with those of core sets established using the conventional clustering methods. This modified heuristic algorithm can also be used to select genotype data with allelic richness and reduced redundancy, and to facilitate management and use of large collections of plant genetic resources in a more efficient way.

采用64个SSR标记对96份云南水稻(Oryza sativa)地方品种和选育品种的遗传多样性进行比较分析。结果发现64个标记都具有多态性,共检测到741个等位基因,每个多态性位点检测到的等位基因数为2-29个,平均11.57个;Nei基因多样性指数(He)范围在0.345(RM321)-0.932(RM1)之间,平均为0.56。水稻品种的遗传多样性并非按地理位置均匀分布,而是在相似系数为0.17的水平上明显分为2个不同类群,即籼稻类群和粳稻类群,且籼粳亚种间的SSR多样性差异不明显,籼稻平均等位基因数(Ap)和Nei基因多样性指数(Ap=10.6,He=0.46)与粳稻品种(Ap=10.7,He=0.48)十分接近,可能与这些品种间存在一定频率的基因交流有关。糯稻和非糯稻在籼稻群和粳稻群中都有表现,没有特别的分布规律。云南栽培稻选育品种与地方稻亲缘关系较近,其遗传基础可能来源于云南水稻地方品种。本研究结果表明,SSR标记能较好地区分云南栽培稻品种,且云南水稻地方品种遗传多样性丰富,存在大量的优质性状可供育种实践选择。
