Denitrification has been long thought to be a unique characteristic of prokaryotes, but in recent years, several filamentous fungi and yeasts were found to exhibit denitrifying activities. This paper deals with the examination of denitrification capabilities by mix-cultures of the fungus (Fusarium oxysporum) and the bacterium (Pseudomonas stutzeri TR2) in combination with a specific medium and using a synthetic wastewater of defined quality. The results revealed that P. stutzeri TR2 has strong and fast denitrifying capabilities under anaerobic conditions, and that co-denitrification of mix-cultures with F. oxysporum and P. stutzeri TR2 was more effective to remove nitrate under limited oxygen conditions. P. stutzeri TR2 was able to remove nitrate completely during cultivation for 12 hr in the specific medium and in mixed culture with F. oxysporum. A rapid N 2 evolution by mixed culture with F. oxysporum and P. stutzeri TR2 was observed in both mixed culture medium and synthetic wastewater. Using synthetic wastewater with a defined composition, about 87% of the nitrate was eliminated to form about 420μmol of N 2 from 1.0mmol of NO-3 by co-denitrification of F. oxysporum and P. stutzeri TR2 after incubation for 6days. In co-cultures of F. oxysporum and P. stutzeri TR2, N2O produced by F. oxysporum was rapidly consumed by P. stutzeri TR2. This indicated that mixed culture of F. oxysporum and P. stutzeri TR2 can be used to remove nitrate and nitrite from wastewater effectively.

To understand the reality of gambling disorder caused by playing pachinko/pachislot, a national pachinko/pachislot survey was conducted. Based on the survey result, we examined the appearance ratio and the characteristics of individuals with a suspected pachinko-pachislot playing disorder. The analysis result indicated that approximately 0.4% of survey respondents were suspected to have the disorder. This appearance ratio was comparable to the prevalence of gambling disorder in the general population. Those who had a suspected disorder were likely to be divorced, and have no savings. Meanwhile, no distinctive characteristics were found in their gender, annual household income, or the highest educational attainment.

Pachinko and pachislot are unique forms of entertainment that dominate gambling activities in Japan. In this study, a web survey and interview were conducted in order to adjust three scales (DSM-5, SOGS, and PGSI) to pachinko/pachislot and explore an appropriate cutoff point for each of them. Using the assessment result in the interview as the outcome, the ROC curve of each scale was examined. The cutoff points were 4, 7, and 8 and the area under the curves (AUC) were 0.730, 0.783, and 0.724 for the DSM-5, SOGS, and PGSI, respectively. The study found that the type and situation of gambling influenced cutoff points in different ways depending on the questions asked in the scale.

目的了解维生素D受体(VDR)在SD大鼠慢性非细菌性前列腺炎中的表达并研究VDR配体(BXL-35)对SD大鼠慢性非细菌性前列腺炎的治疗作用,探讨其可能的机制。方法60只10月龄雄性SD大鼠,随机分正常对照组、慢性非细菌性前列腺炎模型组以及BXL-35治疗慢性非细菌性前列腺炎组。采用RT-PCR对各组SD大鼠前列腺组织中VDRmRNA表达水平进行半定量分析:用免疫组织化学技术检测各组TNF-á,IFN-γ,NF-kB, IkBá的表达水平来判断BXL-35治疗SD大鼠慢性非细菌性前列腺炎的作用。结果(1)前列腺炎模型组VDRmRNA表达水平明显低于正常对照组和BXL-35治疗组(P<0.01);(2)BXL-35治疗组前列腺组织的炎症反应减轻,与前列腺炎模型组比较,其TNF-á,IFN-γ,NF-kB,表达水平明显下降(P<0.01)而IkBá则增高(P<0.01)。结论VDR可能参与了慢性非细菌性前列腺炎的发病机制,其配体能有效抑制前列腺炎症。

我们就上海地区收集的材料,对中国人的枕骨大孔及其邻近的结构作了一些观察,择要如下:1.枕骨大孔呈现六种不同的形状:(1)卵圆形(2)菱形(3)椭圆形(4)圆形(5)蕈形(6)六角形比Martin氏所报导的四种形式多后两种。2.髁后管的出现率与陆氏所得之结果大致相同,与Wood-Jones的材料相差也不大。但发现髁后管的前端有时不开口于乙状沟,而通到颈静脉孔。3.关于枕骨大孔前缘一带出现的骨突,我们根据位置的不同分为三类:(1)枕前棘(2)髁前结节(3)斜坡后棘4.通过整套骨骼检查,以及实地解剖的观察,我们认为这些骨突的出现,可能是由于韧带的牵引及骨化,而与鸟类和爬虫类的第三髁,并非同源结构。
