褪黑素对运动员体内自由基代谢及免疫功能影响的研究

采用实验法，观察服用褪黑素后，对皮划艇运动员体内自由基代谢厦免疫功能的影响。结果显示，与对照组比较，服用褪黑素后，在中、大负荷运动后运动员体内血清中超氧化物歧化酶（SOD）的含量显著提高，过氧化代谢产物丙二醛（MDA）的产生减少，同时机体血清中白细胞介素2（IL-2）、补体C3、C4的浓度得到提高，表明褪黑素可以改善机体清除自由基的能力和增强机体的免疫功能。     

基于江苏太仓农村土地承包经营权融资担保的法律问题探析

金融改革背景下,农村土地融资担保纷纷在各地开展实践试点。土地承包经营权能否抵押的讨论成为焦点。本文通过实地调研的方式,走访了江苏省太仓市的村镇,分析了“太仓模式”的创新之处和存在问题。在分析影响土地承包经营权抵押担保的因素后,提出建立统一的不动产登记制度、设计合理的土地定价机制、健全土地流转市场的对策。     

英国大学生学费与资助政策改革及启示

从20世纪初到70年代末,英国政府在大学实行的是免费加助学金政策,在80年代以后,经济困境使得这种政策有所改变.2004年的<高等教育法案(草案)>,又提出了新的学费政策和资助制度.英国大学学费与资助政策的演变与近年来的一系列改革值得我们认真思考和借鉴.     

Effect of selected fungi on the reduction of gossypol levels and nutritional value during solid substrate fermentation of cottonseed meal

The objective of this work was to investigate the effect of six individual strains of fungi on the reduction of gossypol levels and nutritional value during solid substrate fen＇aentation of cottonseed meal （CSM）. Six groups of disinfected CSM substrate were incubated for 48 h after inoculation with either of the fungi C. capsuligena ZD- 1, C. tropicalis ZD-3, S. cerevisae ZD-5, A. terricola ZD-6, A. oryzae ZD-7, or A. niger ZD-8. One not inoculated group （substrate） was used as a control. Levels of initial and final free gossypol （FG）, crude protein （CP）, amino acids （AA） and in vitro digestibility were assayed. The experiment was done in triplicate. The experimental results indicated that microbial fermentation could greatly decrease （P〈0.05） FG levels in CSM. The detoxification efficiency differed between the species of microorganisms applied. From the perspective of reducing CSM potential toxicity, C. tropicalis ZD-3 was most successful followed by S. cerevisae ZD-5 and A. niger ZD-8. They could reduce FG levels of CSM to 29.8, 63.07 and 81.50 mg/kg based on DM （dry matter）, respectively, and their detoxification rates were 94.57%, 88.51% and 85.16%, respectively. If crude protein, amino acids content and their in vitro digestibility were also taken into account, Aniger ZD-8 may be the best choice. The CP content of CSM substrate fermented by C. tropicalis ZD-3 and A. niger ZD-8 were improved by 10.76% and 22.24%; the TAA （total amino acids） contents were increased by 7.06% and 11.46%, and the EAA （essential amino acids） were raised by 7.77% and 12.64%, respectively. Especially, the levels of methionine, lysine and threonine were improved greatly （P〈0.05）. The in vitro CP digestibility of CSM fermented by C. tropicalis ZD-3 and A. niger ZD-8 was improved by 13.42% and 18.22%, the TAA were increased by 17.75% and 22.88%, and the EAA by 16.61% and 21.01%, respectively. In addition, the in vitro digestibility of methionine, lysine and threonine was also improved greatly （P〈0.05）.

生物自由基与运动性疲劳的研究进展

运动性疲劳是一个十分复杂的生理过程,并受到多种外在因素的影响,迄今为止人们仍在不断地探求其产生的运动生化和生物学机理,并且由于研究的角度不同从而也产生了多种比较成熟的说法。本文就运动性疲劳国际运动生化学术会议上所下的结论认为:运动性疲劳是机体生理过劳的机制问题,对近几年来研究的热点——自由基与运动性疲劳关系研究的最新进展作一论述,为促进该研究领域的进一步深入指出方向。

金融深化与国家助学贷款的政策调适

国家助学贷款政策所面临的现实困境,与金融深化进程中国有商业银行的政策偏好密切相关。国有商业银行在金融深化进程中存在金融支持与市场化两种取向,由于受到双重目标的约束,国有商业银行在谋求两者之间的平衡时,偏重于金融支持政策的运用,风险约束下的市场化取向只是处于渐进增强的过程。为此,以风险分担的形式来降低国有商业银行风险、并试图解决“惜贷”问题的政策进路缺乏实效,有必要通过制度创新来推动国家助学贷款的发展。     

Why free does not mean fair: Investigating users’ distributive equity perceptions of data-driven services

Individuals are supposed to perform a privacy risk-benefit analysis when deciding to transact with a free data-driven service provider. Building on equity theory, this article suggests that users incorporate the net value for providers in their trade-off. Based on two pre-studies and an experimental survey study among 200 free data-driven service users, we provide evidence that users’ balance their own net value (benefits minus risks) as well as providers’ net value from monetizing users’ data. This leads to distributive equity perceptions which, in turn, affect users’ satisfaction with the service and thus long-term success of the user-provider-relationship. In this vein, a distributive equity scale for the context of data-driven services is developed. Implications for research, providers and users are discussed.     

The impact of a community free swimming programme for young people (under 19) in England

A national free swimming programme for under 16s in England was a central government initiative to increase participation in 2008/09, although not all local authorities adopted it. One implemented a bespoke free swimming initiative (FSI) for under 19s in the community instead, aiming to improve the health of young people through the programme and provide value for money for managers. The FSI saw 33% of the eligible population participating at least once. However, the programme evaluation demonstrated that, despite cost being removed, participation decreased over the programme. Furthermore, the FSI had a large market penetration effect, where the majority of participants were already swimming regularly prior to the intervention. Overall, the programme provided some health benefits to the more engaged participants, but in terms of wider social benefit there was little evidence to suggest the intervention had any additional impact. The cost per swim of the community investment was almost six times more per head than the central government funded scheme, suggesting that widespread programming did not provide value for money when compared to a more targeted programme.
