1Antioxidants,inflammation and cardiovascular disease显示文摘Multiple factors are involved in the etiology of cardiovascular disease(CVD). Pathological changes occur in a variety of cell types long before symptoms become apparent and diagnosis is made. Dysregulation of physiological functions are associated with the activation of immune cells,leading to local and finally systemic inflammation that is characterized by production of high levels of reactive oxygen species(ROS). Patients suffering from inflammatory diseases often present with diminished levels of antioxidants either due to insufficient dietary intake or,and even more likely,due to increased demand in situations of overwhelming ROS production by activated immune effector cells like macrophages. Antioxidants are suggested to beneficially interfere with diseases-related oxidative stress,however the interplay of endogenous and exogenous antioxidants with the overall redox system is complex. Moreover,molecular mechanisms underlying oxidative stress in CVD are not fully elucidated. Metabolic dybalances are suggested to play a major role in disease onset and progression. Several central signalingpathways involved in the regulation of immunological,metabolic and endothelial function are regulated in a redox-sensitive manner. During cellular immune response,interferon γ-dependent pathways are activated such as tryptophan breakdown by the enzyme indoleamine 2,3-dioxygenase(IDO) in monocyte-derived macrophages,fibroblasts,endothelial and epithelial cells. Neopterin,a marker of oxidative stress and immune activation is produced by GTP-cyclohydrolase Ⅰ in macrophages and dendritic cells. Nitric oxide synthase(NOS) is induced in several cell types to generate nitric oxide(NO). NO,despite its low reactivity,is a potent antioxidant involved in the regulation of the vasomotor tone and of immunomodulatory signaling pathways. NO inhibits the expression and function of IDO. Function of NOS requires the cofactor tetrahydrobiopterin(BH4),which is produced in humans primarily by fibroblasts and endothelial cells. Highly toxic peroxynitrite(ONOO-) is formed solely in the presence of superoxide anion(O2-). Neopterin and kynurenine to tryptophan ratio(Kyn/Trp),as an estimate of IDO enzyme activity,are robust markers of immune activation in vitro and in vivo. Both these diagnostic parameters are able to predict cardiovascular and overall mortality in patients at risk. Likewise,a significant association exists between increase of neopterin concentrations and Kyn/Trp ratio values and the lowering of plasma levels of vitamin-C,-E and-B. Vitamin-B deficiency is usually accompanied by increased plasma homoycsteine. Additional determination of NO metabolites,BH4 and plasma antioxidants in patients with CVD and related clinical settings can be helpful to improve the understanding of redox-regulation in health and disease and might provide a rationale for potential antioxidant therapies in CVD.Harald Mangge Kathrin Becker Dietmar Fuchs Johanna M Gostner 2014World Journal of Cardiology2014,6,6:25
2信息资本主义及互联网的劳工显示文摘本文认为在信息资本主义中,阶级的概念不能画地为牢地将资本家归为一个阶级,而将劳工划为另一类阶级。阶级的概念必须扩展到每位创造以及再创造共同经验空间的个人,例如包括在互联网上通过实践生产内容的用户。这些空间和经验被占用了,从而为资本所征用和开发,且为资本积累效劳。信息资本主义的崛起要求我们重新思考阶级的概念并将其与脑力劳动结合起来。Christian Fuchs 陈婉琳(译) 黄炎宁(译) 2014新闻大学2014,,5:19
3颈椎前路减压术合并椎动脉损伤显示文摘目的 探讨颈椎前路减压术中椎动脉损伤的危险因素及其处理方法。方法 1980年 1月~ 1998年 12月,对 720例患者行颈椎前路减压术,减压范围包括 1~ 3个椎间隙并行椎体次全切除。术中采用高速磨钻切除骨及椎间盘组织。 630例患者同时行颈椎前路 Caspar钢板内固定术。 3例行椎间减压时向侧方切除过多,导致椎动脉损伤,采用明胶海绵加游离肌片局部填塞止血。结果 720例中椎动脉损伤发生率为 0.4%, 3例均压迫止血成功,无一例出现脑缺血等神经系统症状。结论 颈椎前路减压时不应跨越钩椎关节,局部明胶海绵加游离肌片填塞是有效的椎动脉止血方法。任先军 Caspar W Fuchs GA 2000中华骨科杂志2000,20,8:16
4Proposal of an ultrasonographic classification for hepatic alveolar echinococcosis: Echinococcosis multilocularis Ulm classification-ultrasound显示文摘AIM: To establish an ultrasonographic classification based on a large sample of patients with confirmed hepatic alveolar echinococcosis(AE).METHODS: Clinical data and ultrasonography(US) findings of 185 patients(100 males; 85 females; mean age at diagnosis: 51.4 ± 17.6 years; mean age at time of US examination: 58.7 ± 18.2 years) were retrospectively reviewed with respect to the US morphology of hepatic AE lesions. The sonomorphological findings were grouped according to a five-part classification scheme.RESULTS: Application of the new classification resulted in the following distribution of sonomorphological patterns among the patients examined: hailstorm(54.1%); pseudocystic(13.5%); ossification(13.0%); hemangioma-like(8.1%); and metastasis-like(6.5%). Only 4.9% of lesions could not be assigned to a sonomorphological pattern.CONCLUSION: The sonomorphological classification proposed in the present study facilitates the diagnosis,interpretation and comparison of hepatic alveolar echinococcosis in routine practice and in the context of scientific studies.Wolfgang Kratzer Beate Gruener Tanja EM Kaltenbach Sarina Ansari-Bitzenberger Peter Kern Michael Fuchs Richard A Mason Thomas FE Barth Mark M Haenle Andreas Hillenbrand Suemeyra Oeztuerk Tilmann Graeter 2015World Journal of Gastroenterology2015,21,43:16
5Sedimentation acceleration of remanent iron oxide by magnetic flocculation显示文摘Sedimentation based processes are widely used in industry to separate particles from a liquid phase. Since the advent of the 'Nanoworld' the demand for effective separation technologies has rapidly risen, calling for the development of new separation concepts, one of which lies in hybrid separation using the superposition of a magnetic field for magnetic particles. Possible product portfolio of such separation consists of pigment production, nanomagnetics production for electronics and bio separation. A promising step in that direction is magnetic field enhanced cake filtration, which has by now progressed from batch to continuous operation. In sedimentation processes in a mass force field the settling behaviour of particles strongly depends on physico-chemical properties, concentration and size distribution of the particles. By adjusting the pH, the interparticle forces, in particular the electrostatic repulsion, can be manipulated. For remanent magnetic particles such as magnetite, pre-treatment in a magnetic field could lead to a change of interparticle interactions. By magnetizing the particles apart from van der Waals attraction and electrostatic repulsion, an additional potential is induced, the magnetic attraction, which could easily dominate the other potentials and result in agglomeration in the primary minimum. By sedimentation analysis, a wide spectrum of parameters like pH, magnetic field strength and concentration have been investigated. The results show a strong increase of sedimentation velocity by magnetic flocculation of the raw suspension. This leads to a rise in throughput due to the acceleration of sedimentation kinetics by imparting a non-chemical interaction to the physico-chemical properties in the feed stream of the separation apparatus.Mathias Stolarski Christian Eichholz Benjamin Fuchs Hermann Nirschl 2007China Particuology2007,5,1:12

12声激励下自由射流的涡量场显示文摘本文目的是研究声激励对自由射流流场结构的影响。采用多重网格方法对声激励下三维自由射流(Re=2200)的空间演化做大涡模拟。比较了无激励情况和不同频率声激励下射流涡量场的改变。计算表明,当声激励频率接近射流优势频率时,涡量场结构变化显著。周向涡量集中卷起形成大的涡环,射流径向扩展增大。当激励频率接近优势频率两倍时,有涡合并现象,说明出现次谐波。当激励频率远高于优势频率时,流场结构与无激励情况差别不大。本文还给出在接近优势频率的激励下射流中的流向涡量的分布,定性上与实验观察相同。朱旻明 赵平辉 陈义良 白雪松 Laszlo Fuchs 2012工程热物理学报2012,33,10:5
