马齿苋对热应激小鼠空肠HSP70及肝脏抗氧化能力的影响

旨在探究马齿苋水提物(aqueous extract of Portulaca oleracea L.)对热应激小鼠空肠HSP70含量及肝脏抗氧化能力的影响。选取40只昆明种小鼠,随机分为4组:空白组(C)、热应激组(HS)、马齿苋水提物组(AEP)、维生素C组(Vc),每组10只。热应激组于40℃±1℃环境下每天处理0.5 h,其余时间置于30℃±1℃条件下,C组放置于25℃±1℃,连续6 d后,将小鼠置于25℃±1℃之环境给药治疗7 d。在给药治疗开始后第3天和第7天眶窦采血,处死后采集小鼠空肠、肝脏,测定各组小鼠血清HSP70含量、肝脏SOD、MDA及GSH-Px含量及空肠黏膜HSP70 mRNA表达量的变化。结果显示,与C组比较,热应激可显著提高小鼠空肠黏膜HSP70 mRNA表达量(P<0.01),提高肝脏SOD、MDA和GSH-Px的活性水平(P<0.01)。与HS组比较,给予马齿苋水提物后,可有效降低热应激小鼠血清HSP70含量和空肠黏膜HSP70 mRNA表达量(P<0.01)及肝脏MDA的活性水平(P<0.05),但对SOD和GSH-Px的含量无显著影响(P>0.05)。结论:马齿苋水提物能够通过降低热应激小鼠的氧化应激反应,减少热应激小鼠体内HSP70的表达量,达到良好的抗热应激效果。     

信用证欺诈例外原则的问题分析

信用证是国际贸易中重要的信用结算工具,由于信用证独立抽象的原则,银行只审单而不管实际的货物,导致国际贸易中利用信用证进行欺诈的案件屡屡发生。因此,各国纷纷采取信用证欺诈例外原则来进行补救,但信用证欺诈例外原则的滥用则会损害合法受益人及善意第三方在信用证项下的利益,因此,对欺诈原则应适当地适用,以发挥其最佳效用。     

Care-Politiken,Care-Arbeitsmarkt und Ungleichheit: Schweden,Deutschland und Italien im Vergleich

Social and demographic changes in western societies have led to a (re-)definition of social rights related to care-dependency and the introduction of further regulations of formal and informal care delivery. Care has increasingly become provided in the public sectors – the state, market and civic sector – and new types of cash benefits to support informal family care have been introduced. In this article, the concept of social care is used as a theoretical tool to analyse the relationship between the (re-)definition of social rights, the growth of a regular or grey care labour market and the related development of new forms of inequality according to socio-economic class and ethnicity in the female dominated area. The empirical comparison of the developments in Sweden, Germany and Italy reveals the dimensions of social rights – eligibility criteria, level and types of benefits – which are decisive for the growth of a regular and grey care labour market and the intersection of different forms of inequality.     

Did Jamie Oliver Really Put School Dinners on the Agenda? An Examination of the Role of the Media in Policy Making

Healthy eating is high on the government's agenda in current times and to all intents and purposes the media appears to have played a crucial role in putting it there. While media focus is no doubt intense and playing a vital role in public education (take Jamie Oliver's 2005 Channel 4 documentary, ‘School dinners’, for example), the question that lies at the heart of this article, is whether the media has led the government agenda on healthy eating and school dinners as appears to be the case. A close examination of the evidence suggests otherwise: government policy was already well set before the media began to show a concerted interest and hence its influence on policy‐making is more limited than might be expected. Rather than setting agendas per se, the media's role has been to refine and energise existing policy areas and to facilitate implementation.     

Ordering Disorder – On the Perplexities of the Partnership Literature

The literature on public‐private partnerships (PPP) has proliferated in recent years. However, confusion about the actual meaning of PPP still abounds. As a consequence, contradicting findings and statements about PPP flourish in the literature. This article reviews the literature, and argues that there are different streams of PPP research which operate with qualitatively different notions of the PPP concept. Accordingly the literature is divided into four different PPP ‘approaches’. By doing so the article offers some clarification concerning an increasingly complex concept. The article concludes that an authoritative definition of PPP – one that can encompass all the different variations of the concept currently in use – is not logically possible.     

论无单放货的法律问题

提单是海上货物运输的重要单证.随国际贸易和航运事业的不断发展,提单也从一般托运收据发展成为物权凭证.提单作为代表货物所有权的凭证,可以通过背书转让或抵押,它已具备了一种有价证券的性质.提单的内容、条款以及调整提单的法律也随现代国际贸易的迅速发展而日趋详细和完善.但是,近些年由于航运的变化,无正本提单提货的现象频繁发生,这种行为的产生对传统的航运制度带来的冲击和影响很大.无单放货问题在司法实践和航运实践都引起重视,对这一现象进行研究.     

The Rise of Citizen Groups within the Administration and Parliament in Switzerland

This research note presents three newly interconnected and expanded datasets on interest groups’ (IGs) access to the Swiss political decision‐making process: (1) extra‐parliamentary committee seats occupied by IGs (1980, 2000, 2010), (2) parliamentary (committee) seats occupied by IG representatives (1992‐2015), and (3) consultation replies submitted by IGs (2008‐11). We show that the Swiss system of interest intermediation adapted to the multiplication and organizational consolidation of citizen groups, which defend non‐producer interests and do not provide selective benefits to their members (e.g. environmental groups). The share of access granted to citizen groups has increased in both the administration and parliament, across all federal departments and most legislative committees. Moreover, citizen groups benefit from a larger share of access in the recently revitalized parliament, compared to the administration. This suggests that economic groups’ decline in power is also related to the rise of citizen groups.     

Risks and Realities of Working with Alienated Children

Involvement in custody cases that include accusations of parental alienation—whether as an evaluator, expert witness, lawyer, judge, therapist, provider of a specialized intervention, or researcher—incurs both professional and personal risks. Some risks relate to false negative or false positive identifications of parental alienation that can lead to regulatory agency complaints and public condemnation by the parent who feels wronged by the case outcome. Other risks stem from providing services in an emerging area of practice and working with children who overtly oppose repairing the relationship with their rejected parent. These risks include: unfounded accusations of mistreating children; negatively biased commentary and sensationalist attacks in the media and in social media, professional conferences and journals, and in courtroom testimony; harassment, vilification, and invasion of privacy; threats of violence and public humiliation; shunning and rumor spreading by colleagues; and complaints to regulatory agencies. This article examines circumstances, beliefs, and dynamics that give rise to these risks, suggests precautions to reduce the risk of false accusations against professionals, and offers recommendations for dealing with regulatory agencies. Criticisms that a court or service provider has mistreated a child merit careful scrutiny in the context of the case evidence and empirical data. While some interventions for alienated children raise legitimate concerns, others have been maligned by anecdotal complaints that studies show do not represent the experience of most participants.
