By using a complex of DNA, polyethylenimine and chondroitin sulfate, the in vivo transfection of early secretory antigenic target-6 (ESAT-6) gene into tumor cells was found to cause significant suppression of the tumor growth. In order to apply the method in clinical cancer treatment in dogs and cats, mechanisms underlying the suppressive effects were investigated in a tumor-bearing mouse model. The transfection efficiency was only about 10%, but the transfection of ESAT-6 DNA nevertheless induced systemic immune responses against ESAT-6. By triple injection of ESAT-6 DNA at three day intervals, the tumor was significantly reduced and almost disappeared by 5 days after the start of treatment, and did not increase for more than 15 days after the final treatment. In the immunohistochemistry, a larger number of dendritic cells (DCs)/macrophages expressing ionized calcium-binding adapter molecule 1 and CD3+ T cells was observed in tumors treated with ESAT-6 DNA, and their population further increased significantly by day 5. Moreover, the amount of tumor necrosis factor, which is an apoptosis-inducing factor produced mainly by DCs/macrophages, was greater in the ESAT-6 DNA treated tumors than in controls, and increased with repeat of the treatment. These results indicate that in vivo transfection of ESAT-6 DNA into tumor cells elicits significant inhibition of tumor growth, by inducing potent activity of innate immunity mediated by DCs/macrophages, which may be followed by adaptive immunity against tumor associated antigens, which was elicited by the costimulation with ESAT-6 antigen.

Canine hemangiosarcoma (HSA) is one of the most common mesenchymal tumors in dogs. Its high metastatic and growth rates are usually associated with poor prognosis. Neoplastic cells of HSA can show various levels of cellular atypia in the same mass and may consist of various populations at different differentiated stages. Up to present, however, there is no report analyzing their differentiation states by comparing cellular atypia with differentiation-related protein expressions. To evaluate whether cellular atypia can be used as a differentiation marker in HSA, we analyzed correlation between cellular atypia and intensities of CD31 and von Willebrand Factor (vWF) staining in HSA cases. We also compared cellular atypia and expression levels of CD31 and vWF in each growth patterns. Our results show that cellular atypia was negatively correlated to CD31 and vWF expression levels but no significant correlation was found between growth patterns and cellular atypia or CD31 and vWF expression levels. Our study suggests that cellular atypia is useful for identifying differentiation levels in HSA cases. This study also provides useful information to determine differentiation levels of cell populations within HSA based only on morphological analysis, which will aid further HSA research such as identifying undifferentiation markers of endothelial cells or finding undifferentiated cell population in tissue sections.

Changes in cognitions about the mood; before,during,and after binge eating were investigated. First, a pilot study was conducted with female university students (N=153) and a questionnaire was developed that consisted of items measuring binge eating disorder (BED) tendencies, eating behavior addiction, and changes in cognition about the mood; before,during, and after eating in relation to three factors: depression/fatigue,self-contempt/anxiety, and restlessness. In the main study, female university students(N=205) that were first divided into three groups:control group, pre-BED tendency group, and BED tendency group responded to this questionnaire. Results indicated the following:(1) The pre-BED and BED tendency groups had higher eating addiction scores compared to the control group;(2) The pre-BED and BED tendency groups had higher cognition of mood scores for all factors before, during, and after eating;(3) Depression/fatigue decreased after compared to befor eating in the control and pre-BED tendency groups, whereas this was not the case in the BED tendency group;(4)Self-contempt/anxiety increased after eating in the pre-BED and BED tendency groups.

本研究の目的は,電子メディアの世界においてオンライン百科事典として参照されるWikipedia が,印刷メディアの世界で確立された百科事典の概念に対応するものであるかを明らかにすることである。対応関係を議論する上では,各メディアの世界が支えている知識の編成において百科事典とWikipedia がそれぞれ占める位置づけを考慮することが必要である。そこで,本研究では,百科事典とWikipedia それぞれの役割とそれらの役割を支える属性に着目して分析を行った。まず,百科事典について議論,論究した文献をレビューし,百科事典の役割と属性について分析を行った。次に,Wikipedia について調査,分析を行った文献をレビューし,Wikipedia が百科事典と同じ役割を果たし,同様の属性を有するかについて分析を行った。結論として,個々の利用という状況を除いて,Wikipedia は百科事典と概念的に対応しないことが示された。この結論はまた,電子メディアの世界におけるWikipedia の位置づけは印刷メディアの世界における百科事典の位置づけとは異なることを示唆している。

復興庁職員によるツイッターでの不適切発言事案が発生したことから,総務省は,同様の事案の再発防止を期する観点から、各府省庁等に対して職員の服務規律の徹底を求めるとともに、「国家公務員のソーシャルメディアの私的利用に当たっての留意点」 を取りまとめ、各府省庁等に対して、これを参考に職員への周知徹底を行うほか、必要に応じて、内規の制定、研修の実施等を行うよう求めている。本発表では,同取りまとめの意義を,具体的事例を交えて解説するとともに,その影響等につき考察する。Followed by the careless tweet case by the official of Reconstruction Agency, Government of Japan, Ministry of Internal Affairs and Communications, Government of Japan (MIC) announced government agencies for the compliance of rules for officials and published "Points for attention for personal use of social media by government officials". MIC required government agencies to refer this "Points", set internal rules and have in-house trainings. This paper examines the "Points" with cases and considers the impact of it.

2012年、中国山東省青島市で日本の介護保険に類似する「長期医療護理保険」の試験的導入が開始された。中国は、2035年に2人の労働者が1人の高齢者を支える「超高齢社会」を迎えると推測されており、「一人っ子政策」の完全撤廃が決定された一方、高齢化に対応する社会保障・福祉制度の整備が急務となっている。本稿は、中国における高齢化対応政策の変遷と介護保険制度の試験導入の過程を概観し、今後、超高齢社会への対応を迫られる中国の社会保障制度の運営と持続可能性、財政的課題、国際比較などの多様な視角から分析を行うための初期的な考察を行うものである。

A methanol extract from unripe Japanese apricot showed inhibitory activity of Helicobacter pylori motility. Inhibitory compound 1 was isolated and identified as (+)-syringaresinol (1) by spectoroscopic means. (+)-Syringaresinol (1) inhibited >90% of the H. pylori motility at a concentration of 500 μg/ml and the IC50 value was 50 μg/ml.
