Low mannose-binding lectin function is associated with sepsis in adult patients

Mannose-binding lectin (MBL) is an innate immune system pattern recognition molecule that kills a wide range of pathogens via the lectin complement pathway. MBL deficiency is associated with severe infection but the best measure of this deficiency is undecided. We investigated the influence of MBL functional deficiency on the development of sepsis in 195 adult patients, 166 of whom had bloodstream infection and 35 had pneumonia. Results were compared with 236 blood donor controls. MBL function (C4b deposition) and levels were measured by enzyme-linked immunosorbent assay. Using receiver-operator characteristics of MBL function in healthy controls, we identified a level of < 0.2 U mu L-1 as a highly discriminative marker of low MBL2 genotypes. Median MBL function was lower in sepsis patients (0.18 U mu L-1) than in controls (0.48 U mu L-1, P < 0.001). MBL functional deficiency was more common in sepsis patients than controls (P < 0.001). MBL functional deficient patients had significantly higher sequential organ failure assessment (SOFA) scores and higher MBL function and levels were found in patients with SOFA scores predictive of good outcome. Deficiency of MBL function appears to be associated with bloodstream infection and the development of septic shock. High MBL levels may be protective against severe sepsis. © 2006 Federation of European Microbiological Societies Published by Blackwell Publishing Ltd. All rights reserved.

Retinoid signaling determines germ cell fate in mice

Germ cells in the mouse embryo can develop as oocytes or spermatogonia, depending on molecular cues that have not been identified. We found that retinoic acid, produced by mesonephroi of both sexes, causes germ cells in the ovary to enter meiosis and inititate oogenesis. Meiosis is retarded in the fetal testis by the action of the retinoid-degrading enzyme CYP26B1, ultimately leading to spermatogenesis. In testes of Cyp26b1-knockout mouse embryos, germ cells enter meiosis precociously, as if in a normal ovary. Thus, precise regulation of retinoid levels during fetal gonad development provides the molecular control mechanism that specifies germ cell fate.

The PCNA-associated factor KIAA0101/p15(PAF) binds the potential tumor suppressor product p33ING1b

The KIAA0101/p15(PAF)/OEATC-1 protein was initially isolated in a yeast two-hybrid screen for proliferating cell nuclear antigen (PCNA) binding partners, and was shown to bind PCNA competitively with the cell cycle regulator p21(WAF). PCNA is involved in DNA replication and damage repair. Using polyclonal antisera raised against a p15(PAF) fusion protein, we have shown that in a range of mammalian tumor and non-tumor cell lines the endogenous p15(PAF) protein localises to the nucleus and the mitochondria. Under normal conditions no co-localisation with PCNA could be detected, however following exposure to UV it was possible to co-immunoprecipitate p15(PAF) and PCNA from a number of cell lines, suggesting a UV-enhanced association of the two proteins. Overexpression of p15(PAF) in mammalian cells was also found to protect cells from UV-induced cell death. Based on similarities between the behaviour of p15(PAF) and the potential tumor suppressor product p33ING1b, we have further shown that these two proteins interact in the same complex in cell cultures. This suggests that p15(PAF) forms part of a larger protein complex potentially involved in the regulation of DNA repair, apoptosis and cell cycle progression. (c) 2005 Elsevier Inc.

The curious absence of inter-municipal co-operation in England

In Europe local authorities often work with their neighbouring municipalities, whether to address a specific task or goal or through the course of regular policy making and implementation. In England, however, inter-municipal co-operation (IMC) is less common. Councils may work with service providers from the private and non-profit sectors but less often with neighbouring local authorities. Why this is the case may be explained by a number of historical and policy factors that often encourage councils to compete, rather than to work collaboratively with each other. The present government has encouraged councils to work in partnership with other organizations but there are few examples of increased horizontal cooperation between local authorities. Instead the prevailing model remains fixed on vertical co-working predicated on a principal-agent relationship between higher and lower tiers of government.

Institutional shifts in inter-municipal service delivery:an analysis of developments in eight Western European countries

Comparative research on inter-municipal cooperation in eight European countries shows that there is a great variety of institutional arrangements for cooperation across the different countries. Also, these arrangements tend to change over time in terms of the scope of cooperation among partners, their composition and the degree of organizational integration. This article describes and analyzes the variety of and shifts in institutional arrangements for a specific class of inter-municipal cooperation arrangements: those that are set up to provide for the joint delivery of public services. It is argued that specific arrangements are typically the outcomes of interaction between national institutional contexts,?environmental factors and local preferences.

The effectiveness of an innovative intervention aimed at reducing binge drinking among young people:results from a pilot study

Aims: To assess the effectiveness of a digital-story intervention (short videos made by young people) seeking to reduce the prevalence of young people's binge drinking in Caerphilly. Method: A quasi-experimental design was adopted with three intervention sites and one control site providing the sample (mainly aged 1415 years). Three rounds of self-completion questionnaires, completed prior (T1), immediately after (T2) and 6 months after the intervention (T3). Findings: A total of 1031 questionnaires completed across the three time-points. Two-factor ANOVAs revealed a positive effect on knowledge for the intervention sample. The intervention group results showed stable attitudes towards drinking at the three time-points whilst the control group showed increasing positive attitudes towards drunkenness over the same time period. Intentions towards drunkenness were higher in the control group than the intervention group at T2 (ControlT1 Mean 3.37, T2 Mean 3.90; interventionT1 Mean 3.26, T2 Mean 3.29). Intervention participants got drunk on fewer occasions in the last week (mean occasions last week 1.57) compared to control participants (mean occasions last week 2.00), with the difference approaching statistical significance (F 1.90, p 0.07). Conclusions: Promoting negative attitudes towards drunkenness, alongside a greater sense of control and potential regret about drunkenness are likely to be important factors when considering how to change people's intentions to drink. The study shows the potential to reduce the frequency of drinking behaviour when intentions are changed, and provides recommendations for future interventions of this nature. © 2010 Informa UK Ltd.
