摘要： Congenital disorder of glycosylation type Id is an inherited glycosylation dis order based on a defect of the first mannosyltransferase involved in N-glycan b iosynthesis inside the endoplasmic reticulum. Only one patient with this disease has been described until now. In this article, a second patient and an aflected fetus are described. The patient showed abnormal glycosylation of several plasm a proteins as demonstrated by isoelectric focusing and Western blot. Lipid-link ed oligosaccharides in the endoplasmic reticulum, reflecting early N-glycan ass embly, revealed an accumulation of immature Man5GlcNAc2-glycans in fibroblasts of the patient. Chorion cells of the affected fetus showed the same characterist ic lipid-linked oligosaccharides pattern. However, the fetus had a normal glyco sylation of several plasma proteins. Some fetal glycoproteins are known to be de rived from the mother, but even glycoproteins that do not cross the placenta wer e normally glycosylated in the affected fetus. Maternal or placental factors tha t partially compensate for the glycosylation defect in the fetal stage must be p roposed and may be relevant for the therapy of these disorders in the future.

摘要： The construction of artificial biofilms with defined internal architectures is described. Bacterial cells are suspended in a low conductivity medium, guided to specific areas in a ,microelectrode array by dielectrophoresis (DEP), and then immobilised using the flocculating agent poly(ethylenimine). Multispecies biofilms can be constructed by introducing different species at different times. The rapid construction of such biofilms with defined internal architectures provides, when combined with visual reporters of gene activity, a powerful new method for the investigation of the effects of the spatial organisation on interactions between bacterial species in biofilms. To demonstrate the utility of the technique as a method for investigating metabolic interactions in biofilms, aggregates were constructed from Acinetobacter sp. C6 and Pseudomonas putida::gfp. The Acinetobacter degrades benzyl alcohol, overproducing benzoate, which in turn is consumed by the Pseudomonas strain. The P. putida has a chromosomally expressed cassette encoding a gfp downstream of the promoter which controls degradation of benzoate, making the interaction between the two strains in the metabolism of benzyl alcohol visible by the production of green fluorescent protein (GFP). Microscopic observation of the biofilms, including the use of confocal laser scanning microscopy (CLSM), confirmed that metabolic exchange occurred. In addition, it was observed that the bacteria appear to have a preferred biofilm architecture, with P putida in the bottom layer, and Acinetobacter at the top. (c) 2005 Elsevier B.V.

关键词： alcohol dependence   type I-Type II   subtype  

摘要： Objective: The Type A-Type B multidimensional classification model has been useful for identifying a subgroup of alcohol dependent drinkers with more severe psychosocial problems and a poor prognosis. Evidence suggests its dimensions may be useful for identifying problem drinkers in the general population at risk for developing alcohol dependence. To date, the model has not yet been investigated for this purpose. The present study investigated the Type A/Type B distinction in a community sample of problem drinkers as well as its predictive validity among problem drinkers with no history of alcohol dependence. Method: Households from a geographically delimited area in the United States were designated via random digit dialing and randomly designated members were screened for eligibility. A total of 876 participants met eligibility criteria and completed a structured interview (AUDADIS) on alcohol and other health related behaviors at baseline and at 1-year follow-up. A k-means cluster analysis was performed to identify subgroups of problem drinkers. Results: A two-cluster solution adequately fit the data and identified two main subgroups of problem drinkers consistent with a Type A-Type B distinction. The group differences held among those with and without a history of alcohol dependence and the subset of Type B drinkers with no history of alcohol dependence were approximately five times (beta=1.56, p <= 0.01) more likely to have an initial onset of dependence than Type A drinkers at 1-year follow-tip. In contrast, a DSM-IV alcohol abuse diagnosis at baseline did not predict 1-year onset of dependence. Conclusions: The Type A-Type B model is useful for identifying untreated problem drinkers at risk for developing alcohol dependence. This model may facilitate the development of more targeted prevention efforts. (c) 2005 Elsevier Ltd. All rights reserved.

关键词： Cross-validation   Error rates   Gene selection   Selection bias   Support vector machine  

摘要： Currently there is much interest in using microarray gene-expression data to form prediction rules for the diagnosis of patient outcomes. A process of gene selection is usually carried out first to find those genes that are most useful according to some criterion for distinguishing between the given classes of tissue samples. However, there is a bias (selection bias) introduced in the estimate of the final version of a prediction rule that has been formed from a smaller subset of the genes that have been selected according to some optimality criterion. In this paper, we focus on the bias that arises when a full data set is not available in the first instance and the prediction rule is formed subsequently by working with the top-ranked genes from the full set. We demonstrate how large the subset of top genes must be before this selection bias is not of practical consequence. © 2005 Elsevier B.V. All rights reserved.

摘要： “为了解决一些用人单位不愿意与劳动者订立书面劳动合同的问题,草案明确规定,已存在劳动关系,但是双方未以书面形式订立劳动合同的,除劳动者有其他意思表示外,视为双方已订立无固定期限劳动合同。但是此种处理事实劳动关系的方式引起了很大争议,大多数人认为这是保护劳动者合法权益的有力举措,并对如何进一步完善该条款提出了建议;也有人认为这样规定有失公平,并且劳动关系双方的自治行为也会受到了不恰当地限制。”

关键词： 合同形式   法定合同形式   法定形式欠缺  

摘要： 合同形式自由与合同形式法定是对立统一的合同形式规制的方式。合同形式的法律规制以自由为原则，法定为例外。探讨法定的合同形式对于正确理解合同形式自由、正确适应法律具有重要的意义。合同采取法定形式的原因在法律发展的不同历史阶段有不同的表现。在法律发展的早期，合同采取法定形式的原因主要是出于“担保”的目的，是对合同法律效力的确认。在现代法上，采取法定合同形式的原因主要是警示目的、标识目的、证据目的以及对社会公共利益、第三人利益、弱势群体利益的法律保护目的等。从操作层面上来看，通过书面形式能够有效的实现以上的法律目的。特别是对于社会公共利益来说，只有通过审批、登记这些特殊的法定书面形式，国家才能有效的对私法主体之间的法律关系进行管理和控制。类型法定是合同形式法定的题中之意。法定合同形式的类型主要包括一般书面形式与特殊书面形式。一般书面形式包括合同书、信件和数据电文，本文对这三种类型的书面形式所涉及的法律问题，例如书面形式的构成、签章等进行了探讨。特殊的书面形式包括批准与登记。本文分析了国内外关于法定合同形式的立法例，在此基础上提出了法定合同形式的确立标准。立法者在确认哪些类型的合同应该采取法定形式时主要考虑了以下几个因素：法律传统、避免当事人轻率决定、民事关系的复杂程度、维护交易安全、保护国家利益、社会公共利益以及特定群体的利益。违反法定形式的法律后果一般为无效。在符合条件的情况下，无效的法律后果可以补救。大陆法系主要采用履行治愈与诚实信用原则两种方式；英美法系主要采用部分履行与禁反言。我国合同法规定了履行治愈的方式，我国的规定存在缺陷，该规定的适应范围应该严格限制。

关键词： 检验科   医院感染   预防  

摘要： 随着现代医学的发展,由医院感染造成的医疗纠纷日趋增多,制约着医疗质量的提高,严重影响了医院的正常发展.在医疗工作中,医院检验科集中了医院送检的患者血液、体液、分泌物、排泄物、穿刺液等检验标本,这些标本大多带有病原微生物,在检验过程中易引起医院感染的发生.检验科作为预防医院感染组织的一个重要部门,在控制院内感染工作中,起着非常重要的作用。[第一段]
