Violent change of seasonal appearance of three hydromedusae species (Hydrozoa, Anthomedusae) from Iwaki City, Fukushima Prefecture, Japan after the disastrous earthquake in 2011
No full textViolent change of a seasonal appearance of Sarsia tubulosa, Turritopsis sp., and Leuckartiara hoepplii, that is a pradator of T. sp. was observed by Kitada, H. in Onahama port, Iwaki City, Fukushima Prefecture, Japan after the disastrous earthquake happened in 2011. Before the disaster (2008-2011) a large number of large (2-3 cm in diameter) S. tubulosa appeared from February to March, being most abundantly in March and a small number of small T. sp. appeared in July, then a small number of large T. sp. appeared in August and September. In contrast after the disaster until 2014 a small number of small S. tublosa appeared in only March and a large number of both small and large T. sp. appeared in the period from July to October. In parallel with such a violent change of T. sp., larger (2-3 times: 2-3 cm in height) Leuckartiara hoepplii (pradator of T. sp.) appeared after the disaster.福島県いわき市小名浜港の定点(アクアマリン福島前)で，サルシアクラゲとベニクラゲ，加えてベニクラゲの捕食者であるカザリクラゲの季節消長について，2008年から2014年まで，ほぼ毎日，北田が目視調査した．その結果，2011年3月11日に勃発した大震災以前は，サルシアクラゲは3月を最多数とし，その前後の2月と4月にも傘高2–3 cmの大型個体が出現し，ベニクラゲは，毎月少数であるが，7月と10月に直径数 mm程度の小型個体，8–9月に傘径1 cmほどの大型個体の出現といった一定の季節消長を示した．しかし，大震災後にはサルシアクラゲの出現個体数は激減し，3月のみに最大個体抜きの出現で少数となった．ベニクラゲでは7–10月にかけての毎月，傘径1 cmほどの大型個体が出現するように変わり，同時に直径数mm 程度の小型個体も出現した．ベニクラゲのこのような激変と並行し，その捕食者であるカザリクラゲは，大震災後には傘高2–3 cm に達する以前の数倍の大きさの個体が出現した

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
