Obesity and the metabolic syndrome and their associated morbidities are major public health issues, whose prevalence will continue to increase in the foreseeable future. Aberrant signaling by the receptors for leptin and insulin plays a pivotal role in development of the metabolic syndrome. More complete molecular-level understanding of how both of these key signaling pathways are regulated is essential for full characterization of obesity, the metabolic syndrome, and type lI diabetes, and for developing novel treatments for these diseases. Phosphorylation of proteins on tyrosine residues plays a key role in mediating the effects of leptin and insulin on their target cells. Here, we discuss the molecular methods by which protein tyrosine phosphatases, which are key physiological regulators of protein phosphorylation in vivo, affect signaling by the leptin and insulin receptors in their major target tissues.

作为一颗从经济上、政治上覆盖着整个地区冉冉升起的新星,作为能够给投资者提供廉价劳动力、丰富原材料、巨大的市场规模和政府给予的优惠措施的一个拥有巨大机会的市场,中国来到了世界。正是因为这些原因,土耳其的投资者们更愿意活跃于中国的市场。最近几年中,土耳其和中国的商业关系得到了快速的发展,但是不断增长的贸易赤字已经威胁到了两国贸易持续发展。土耳其和中国正寻求解决这种贸易赤字的途径。在一次由91个土耳其公司组成的见面会中,产生了建立一个专门服务土耳其出口商的物流中心的想法。除了揭露在两国双边关系发展中成为障碍的主要问题,这篇论文使用了混合法的方法包括定性和定量发来发现土耳其出口商的面对的问题,来在所有候选成为物流中心的城市中找到一个最优港口,并且在影响总运输成本的需求中发现现实生活的随机性。论文中使用的数据均从定性和定量的角度出发。为了搜集到数据,搜寻相关书籍、期刊和港口年鉴和通过互联网寻找相关信息。论文中使用的大量数据中最特别的是从与土耳其公司的面谈中获得的。这些数据能够满足了一篇准确、有效的论文的可靠性的要求。面谈采用半结构式访谈的方式进行,有通过面对面的接触或者通过电话来弄清楚阻碍双边贸易发展的主要问题,并且了解了他们就关于如何避免这些问题的建议。由于过高的运输成本和过长的交付周期,因此建造一个物流中心就是他们在物流领域提出的一个建议。这样就很难和其他竞争者在市场上竞争。为了在候选的城市中,即北京、广州、上海、深圳和天津,选出这个城市,一个基于设施选址的整数规划模型建立起来了,并且是基于减少土耳其公司的运输成本的因素。后来,我们做了蒙特卡罗模拟,为了了解随着时间变化的需求的变化,模型在过去所获得的数据的基础上得到了结果。因此,其对运输成本的影响可以被评估。整数规划模型基于设施选址问题是通过优化软件包解决的;IBM ILOG CPLEX优化工作室为了找到这个城市使公司减少他们的运输成本。为了做仿真,我们使用了相同的软件程序并且通过生成随机的范围在±20%的确定性的需求将模型运行了几次。在面谈过程中研究的结论,就是为了难以减少的贸易赤字的主要物流问题就是较长的交货时间和较高的运输成本。因此,在中国构建一个物流中心作为的解决方案浮现出来,并且一个项目需要开始建造它。基于这个想法,一个模型被解决了,它发现在候选城市中有一个潜在的物流中心,这个物流中心应该建在上海,它的运输费用是18.923百万美元。此外,因为我们假设需求利用过去的数据,蒙特卡罗模拟向我们展示了在未来这个成本还可以在17.599百万美元和19.988百万美元之间变动。论文的局限性在于公司不愿意分享与公司相关的数据并且为研究花费多余的时间。此外,城市选择的决定是在项目范围之内,和模型的因素指示的是土耳其公司。进一步的研究可以使在上海选址的公司拥有最少的运输成本。

A total of 285 paediatricians included 3487 children seen during a period of one week. In a second phase an observational, prospective and multicentre study was conducted and 2069 milk-fed infants with mild gastrointestinal disorders (colic, constipation, regurgitation and diarrhoea) were included. There was a baseline visit (start of treatment) and a final visit four weeks later. The effectiveness of the various Novalac formulas, as well as the satisfaction of the parents/tutors and paediatricians with the dietetic treatment were assessed at the final ***: The prevalence of mild gastrointestinal disorders was 27.8% of all paediatrician consultations (9.2%, 7.8%, 6.1% and 4.6% in relation to colic, constipation, regurgitation and diarrhoea, respectively). The several Novalac adapted milk formulas resolved 88.4% of the mild gastrointestinal disorders. Depending on the type of disorder, differences in response rate were observed. The highest effectiveness was recorded with respect to diarrhoea (92.6%), followed by constipation (91.6%), colic (87.6%) and regurgitation (81%). Overall, 91% of the paediatricians and 88.8% of the parents/tutors were satisfied or very satisfied with the Novalac adapted milk ***: Mild gastrointestinal disorders show a high prevalence in paediatric practice. The Novalac adapted milk formulas have been shown to be effective in treating mild gastrointestinal disorders in milk-fed infants in the context of routine clinical practice.
