Local self‐assembly mechanisms underlie the differential transformation of the proximal and distal cut axonal ends into functional and aberrant growth cones
Authors: Erez Hadas , Spira Micha E. 
Published: January 2008

AbstractFollowing axotomy both the proximal and distal cut axonal ends transform into growth cones. Whereas the growth cone formed by the tip of the proximal segment branch to form neurites (left hand side), the structure formed by the distal cut end fails to grow.

A service‐oriented Grid environment for integration of distributed kidney models and resources
Authors: Chu Xingchen , Lonie Andrew , Harris Peter , Thomas S. Randall , Buyya Rajkumar 
Published: January 2008

AbstractIn this paper, we present a Grid computing platform that provides experimental scientists and analysts with access to computational simulations and knowledge databases hosted in separate laboratories around the world involved with human and animal kidney research. No single laboratory can develop these resources in isolation, and the community of users should no longer need to be dependent upon the specific programming environment in which applications have been developed. This work aims at exploiting the power of high‐bandwidth communications networks for collaborative research and for shared access to knowledge resources. This platform is developed within a specialist community of renal scientists but will be transferable to any other field of research requiring interaction between published literature and databases, theoretical models and simulations and the formulation of effective experimental design.

Human galectins as sensors for apoptosis/necrosis‐associated surface changes of granulocytes and lymphocytes
Authors: Beer Alexandra , André Sabine , Kaltner Herbert , Lensch Martin , Franz Sandra , Sarter Kerstin , Schulze Connie , Gaipl Udo S. , Kern Peter , Herrmann Martin , Gabius Hans‐Joachim 
Published: January 2008

AbstractChanges in the glycomic profile can significantly affect the cells' communication with the environment. Plant lectins have so far been used to address the issue as to whether the courses of apoptosis or necrosis are associated with such alterations. We, here, initiate the study of members of the family of functionally pleiotropic human galectins in this respect. Established protocols for the induction of apoptosis/necrosis of blood cells and for flow cytometry using annexin V/propidium iodide were combined with cell surface staining using biotinylated galectins at a nontoxic concentration. The galectin panel covered members from all three subfamilies. Flow cytometry revealed specific binding of galectins to viable control cells and conspicuous staining differences when testing apoptotic or necrotic cells. Onset and especially progression of cell death led to pronounced reactivity with the proto‐type galectins‐1, ‐2, and ‐7 and tandem‐repeat‐type galectin‐4. Extent of staining depended on the nature and stage of cell death, type of dying cell, and type of galectin. Galectins act as sensors for cell‐death‐associated surface changes. Staining of late‐apoptotic polymorphonuclear cells was particularly strong. Examining the functional significance of this result may reveal a new aspect within the surveillance system to protect against autoinflammation. © 2008 International Society for Analytical Cytology
Single‐ and multi‐ carrier IDMA schemes with cyclic prefixing and zero padding techniques
Authors: Guo Qinghua , Yuan Xiaojun , Ping Li 
Published: January 2008

AbstractIn this paper, we investigate single‐carrier (SC) and multi‐carrier IDMA schemes with cyclic prefixing (CP) and zero padding (ZP) techniques. These schemes are called SC‐IDMA‐CP, SC‐IDMA‐ZP, orthogonal frequency‐division multiplexing (OFDM)‐IDMA‐CP and OFDM‐IDMA‐ZP, respectively. By exploiting the circulant property of channel matrices, the multi‐user detection of these schemes can be efficiently realised with per‐user complexity independent of the number of users and the length of inter‐symbol interference (ISI) channels. We show the potential advantages of ZP‐based schemes in power efficiency and convergence speed. Simulation results are provided to compare the four schemes. Copyright © 2008 John Wiley & Sons, Ltd.
The ANP‐cGMP‐protein kinase G pathway induces a phagocytic phenotype but decreases inflammatory gene expression in microglial cells
Authors: Borán Mariela Susana , Baltrons María Antonia , García Agustina 
Published: January 2008

AbstractReactive gliosis is a prominent feature of CNS injury that involves dramatic changes in glial cell morphology together with increased motility, phagocytic activity, and release of inflammatory mediators. We have recently demonstrated that stimulation of the cGMP‐protein kinase G (PKG) pathway by NO or atrial natriuretic peptide (ANP) regulates cytoskeleton dynamics and motility in rat astrocytes in culture. In this work, we show that the cGMP‐PKG pathway stimulated by ANP, but not by NO, regulates microglial cell morphology by inducing a dramatic reorganization in the actin cytoskeleton. Both ANP (0.01–1.0 μM) and the permeable cGMP analog, dibutyryl‐cGMP (1–100 μM), promote a rapid (maximal at 30 min) and concentration‐dependent increase in size, rounding, and lamellipodia and filopodia formation in rat brain cultured microglia. These morphological changes involve an augment and redistribution of F‐actin and result in increased phagocytic activity. ANP‐induced rearrangements in actin cytoskeleton and inert particle phagocytosis are prevented by the PKG inhibitor, Rp‐8‐Br‐PET‐cGMPS (0.5 μM), and involve inhibition of RhoA GTPase and activation of Rac1 and Cdc42. However, ANP does not induce NO synthase Type 2 (NOS‐2) or tumor necrosis factor‐α expression and is able to decrease lipopolysaccharide (LPS)‐elicited induction of these inflammatory genes. The morphological changes and the decrease of LPS‐induced NOS‐2 expression produced by ANP in cultured microglia are also observed by immunostaining in organotypic cultures from rat hippocampus. These results suggest that stimulation of the ANP‐cGMP‐PKG pathway in microglia could play a beneficial role in the resolution of neuroinflammation by removing dead cells and decreasing levels of proinflammatory mediators. © 2008 Wiley‐Liss, Inc.
Gene expression profiling of astrocytes from hyperammonemic mice reveals altered pathways for water and potassium homeostasis in vivo
Authors: Lichter‐Konecki Uta , Mangin Jean Marie , Gordish‐dressman Heather , Hoffman Eric P. , Gallo Vittorio 
Published: January 2008

AbstractAcute hyperammonemia (HA) causes cerebral edema and brain damage in children with urea cycle disorders (UCDs) and in patients in acute liver failure. Chronic HA is associated with developmental delay and mental retardation in children with UCDs, and with neuropsychiatric symptoms in patients with chronic liver failure. Astrocytes are a major cellular target of hyperammonemic encephalopathy, and changes occurring in these cells are thought to be causally related to the brain edema of acute HA. To study the effect of HA on astrocytes in vivo, we crossed the Otcspf mouse, a mouse with the X‐linked UCD ornithine transcarbamylase (OTC) deficiency, with the hGFAP‐EGFP mouse, a mouse selectively expressing green fluorescent protein in astrocytes. We used FACS to purify astrocytes from the brains of hyperammonemic and healthy Otcspf/GFAP‐EGFP mice. RNA isolated from these astrocytes was used in microarray expression analyses and qRT‐PCR. When compared with healthy littermates, we observed a significant downregulation of the gap‐junction channel connexin 43 (Cx43) the water channel aquaporin 4 (Aqp4) genes, and the astrocytic inward‐rectifying potassium channel (Kir) genes Kir4.1 and Kir5.1 in hyperammonemic mice. Aqp4, Cx43, and Kir4.1/Kir5.1 are co‐localized to astrocytic end‐feet at the brain vasculature, where they regulate potassium and water transport. Since, NH4+ ions can permeate water and K+‐channels, downregulation of these three channels may be a direct effect of elevated blood ammonia levels. Our results suggest that alterations in astrocyte‐mediated water and potassium homeostasis in brain may be key to the development of the brain edema. © 2008 Wiley‐Liss, Inc.
Quality control and homogeneity of Turkish precipitation data
Authors: Göktürk Ozan Mert , Bozkurt Deniz , Şen Ömer Lütfi , Karaca Mehmet 
Published: January 2008

AbstractOutlier trimming and homogeneity checking/correction were performed on the monthly precipitation time series of various lengths from 267 stations in Turkey. Outlier values are usually found during dry summer months, and are concentrated mostly over the southern parts of the country, where the dry period is most pronounced, implying natural extremes rather than wrong measurements. Homogeneity analysis was done using the Standard Normal Homogeneity Test, on an individual monthly basis, which led to many non‐testable series due to lack of reference stations, especially during summer months. Yet, remaining testable months were usually helpful for the assessment of homogenity, revealing a well distributed set of stations that proved to be homogeneous. There were still a number of stations which either could not be tested efficiently, or were classified as inhomogeneous. Lack of metadata is argued to be largely responsible for inefficient homogeneity testing. Copyright © 2008 John Wiley & Sons, Ltd.
The effect of hysteresis on three‐dimensional transient water flow during surface trickle irrigation
Authors: Elmaloglou S. , Diamantopoulos E. 
Published: January 2008

AbstractThe effect of hysteresis on deep percolation, irrigation efficiency and soil water content profiles by surface point sources was studied through the use of a cylindrical flow model which incorporates hysteresis in the soil water characteristic curve (Scott et al., 1983), evaporation from the soil surface and water extraction by roots. Several combinations of discharge rate and irrigation durations were tested. The dripper spacing was 60 × 60 cm. The implementation of the mathematical model took place against two of the twelve USDA soil classes. Water content profiles are presented for a radial distance of 1, 17 and 32.8 cm from the point source and for various times. The results show that hysteresis seems to reduce the water losses under the root zone at the end of the simulation time to a great extent. In addition, it was found that hysteresis reduced the deep percolation more in the coarse‐grained soil than in the fine‐grained soil. Finally, for both soils hysteresis increased the irrigation efficiency. Copyright © 2008 John Wiley & Sons, Ltd.
Farmers' motivation for collective action in irrigation: a statistical approach applied to the Office du Niger in Mali
Authors: Vandersypen K. , Bastiaens L. , Traoré A. , Diakon B. , Raes D. , Jamin J.‐Y. 
Published: January 2008

AbstractThis paper provides a statistical approach to evaluate the prospects of farmers' water management using survey data from the Office du Niger irrigation scheme in Mali. In the Office du Niger, irrigation management transfer made farmers responsible for water management at the tertiary level. This transfer was a part of broader institutional and economic reforms, which have opened up economic opportunities. Using this approach, it can be shown that farmers are diversifying their income at the expense of agricultural activities and rice farming in particular. This trend brings along an increased employment of wage labourers, who have water management among their tasks. It appears, however, that wage labourers are far less motivated to cooperate with fellow farmers, which might jeopardize the prospects for farmers' water management. Based on the analysis, some policy recommendations are formulated. Copyright © 2008 John Wiley & Sons, Ltd.
