GMF is an evolutionarily developed Adf/cofilin‐super family protein involved in the Arp2/3 complex‐mediated organization of the actin cytoskeleton
Authors: Nakano Kentaro , Kuwayama Hidekazu , Kawasaki Masato , Numata Osamu , Takaine Masak 
Published: April 2010

AbstractActin‐depolymerizing factor (ADF)/cofilin is widely expressed in eukaryotes and plays a central role in reorganizing the actin cytoskeleton by disassembling actin filaments. The ADF‐homologous domain (ADF‐H) is conserved in several other actin‐modulating proteins such as twinfilin, Abp1/drebrin, and coactosin. Although these proteins interact with actin via ADF‐H, their effects on actin are not identical to each other. Here, we report a novel ADF/cofilin‐super family protein, Gmf1 (Glia maturation factor‐like protein 1), from the fission yeast Schizosaccharomyces pombe. Gmf1 is a component of actin patches, which are located on the cell cortex and required for endocytosis, and may be involved in the control of the disassembly of actin patches since its overexpression diminishes them. We provide evidence that Gmf1 binds weakly if at all to actin, but it associates with actin‐related protein (Arp) 2/3 complex and suppresses its functions such as the promotion of actin polymerization and branching filaments. Importantly, Arp2/3 complex‐suppressing activity is conserved among GMF‐family proteins from other organisms. Given the functional plasticity of ADF‐H, GMF‐family proteins possibly have changed their target from conventional actin to Arps through molecular evolution. © 2010 Wiley‐Liss, Inc.

AbstractThe ability of dendrimer 2G‐[Si{O(CH2)2N(Me)2+(CH2)2NMe3+(I−)2}]8 (NN16) to transfect a wide range of cell types, as well as the possible biomedical application in direct or indirect inhibition of HIV replication, was investigated. Cells implicated in HIV infection such as primary peripheral blood mononuclear cells (PBMC) and immortalized suspension cells (lymphocytes), primary macrophages and dendritic cells, and immortalized adherent cells (astrocytes and trophoblasts) were analyzed. Dendrimer toxicity was evaluated by mitochondrial activity, cell membrane rupture, release of lactate dehydrogenase, erythrocyte hemolysis, and the effect on global gene expression profiles using whole‐genome human microarrays. Cellular uptake of genetic material was determined using flow cytometry and confocal microscopy. Transfection efficiency and gene knockdown was investigated using dendrimer‐delivered antisense oligonucleotides and small interfering RNA (siRNA). Very little cytotoxicity was detected in a variety of cells relevant to HIV infection and erythrocytes after NN16 dendrimer treatment. Imaging of cellular uptake showed high transfection efficiency of genetic material in all cells tested. Interestingly, NN16 further enhanced the reduction of HIV protein 24 antigen release by antisense oligonucleotides due to improved transfection efficiency. Finally, the dendrimer complexed with siRNA exhibited therapeutic potential by specifically inhibiting cyclooxygenase‐2 gene expression in HIV‐infected nervous system cells. NN16 dendrimers demonstrated the ability to transfect genetic material into a vast array of cells relevant to HIV pathology, combining high efficacy with low toxicity. These results suggest that NN16 dendrimers have the potential to be used as a versatile non‐viral vector for gene therapy against HIV infection.
Coverage‐Dependent Self‐Assembly of Rubrene Molecules on Noble Metal Surfaces Observed by Scanning Tunneling Microscopy
Authors: Pivetta Marina , Blüm Marie‐Christine , Patthey François , Schneider Wolf‐Dieter 
Published: April 2010

AbstractCoverage‐dependent self‐assembly of rubrene molecules on different noble metal surfaces, Au(111) and Au(100), Ag(111) and Ag(100), is presented. On Au(111), the homochiral supramolecular assemblies evolve with increasing rubrene coverage from very small structures composed of a few molecules, to honeycomb islets, and to one‐dimensional chains of supramolecular pentamers. At higher coverage, the racemic mixture of molecules forms close‐packed islands. On Au(100), chains of pentamers and two different types of densely packed islands are formed. On the Ag surfaces, exclusively close‐packed islands are created, independently of the rubrene coverage. Moreover, the role of the chiral nature of the molecules in the self‐assembly process is discussed, as well as the existence of different molecular conformers depending on the supramolecular assembled phase. The observed differences and similarities reflect the influence of the electronic properties and the geometric structure of the various substrates on molecular self‐assembly.
Electrochemical Synthesis of Core–Shell Catalysts for Electrocatalytic Applications
Authors: Kulp Christian , Chen Xingxing , Puschhof Andrea , Schwamborn Stefanie , Somsen Christoph , Schuhmann Wolfgang , Bron Michael 
Published: April 2010

AbstractA novel electrochemical method to prepare platinum shells around carbon‐supported metal nanoparticles (Ru and Au) by pulsed electrodeposition from solutions containing Pt ions is presented. Shell formation is confirmed by characteristic changes in the cyclic voltammograms, and is further evidenced by monitoring particle growth by transmission electron microscopy as well as by energy‐dispersive analysis of X rays (EDX). Scanning electrochemical microscopy and EDX measurements indicate a selective Pt deposition on the metal/carbon catalyst, but not on the glassy carbon substrate. The thus prepared carbon‐supported core–shell nanoparticles are investigated with regard to their activity in electrocatalytic oxygen reduction, which demonstrates the applicability of these materials in electrocatalysis or sensors.
A consideration on R&D direction for future Internet architecture
Authors: Esaki Hiroshi 
Published: April 2010

AbstractThe professional Internet system has been operated for more than 20 years, while preserving the continuous introduction of technical innovations. The Internet architecture, of course including the future Internet, must preserve the following five essential features of the Internet architecture. These are (1) autonomous, (2) distributed, (3) disconnected, (4) inter‐domain, and (5) global operation. The current Internet system is challenged by the following three aspects; global, ubiquitous and mobility.ISOC, Internet Society (www.isoc.org), has initiated the strategic initiative that is focusing on ‘Trust and Identifier’. We must re‐design the identifier, directory service, trust model, routing and communication model for the computer system and for the computer networks. For example, Delay Tolerant Networking or Peer‐to‐Peer system architecture would challenge the introduction of new technological frameworks to the existing Internet. Finally, this paper discusses how to build and how to deploy the future Internet infrastructure. Copyright © 2010 John Wiley & Sons, Ltd.
Vectors for efficient and high‐throughput construction of fluorescent drosophila reporters using the PhiC31 site‐specific integration system

Published: April 2010

AbstractThe fruit fly Drosophila is a leading model system for the study of transcriptional control by cis‐regulatory elements or enhancers. Here, we present a rapid and highly efficient system for the large‐scale analysis of enhancer elements, site‐specifically integrated into the Drosophila genome. This system, which is scalable for either small projects or high‐throughput approaches, makes use of the Gateway cloning technology and the PhiC31 site‐specific integration system, which allows the insertion of constructs at predetermined genomic locations. Thus, this system allows not only a fast and easy analysis of reporter gene expression in live animals, but also the simultaneous analysis of different regulatory outputs on a cellular resolution by recombining in the same animal distinct enhancer elements fused to different fluorescent proteins. genesis 48:452–456, 2010. © 2010 Wiley‐Liss, Inc.
Measurement and modelling of bryophyte evaporation in a boreal forest chronosequence

Published: April 2010

AbstractThe effects of changing climate and disturbance on forest water cycling are not well understood. In particular, bryophytes contribute significantly to forest evapotranspiration in poorly drained boreal forests, but few studies have directly measured this flux and how it changes with stand age and soil drainage. We measured bryophyte evaporation (E) in the field (in CanadianPicea marianaforests of varying ages and soil drainages) and under controlled laboratory conditions, and modelled dailyEusing site‐specific meteorological data to drive a Penman–Monteith‐based model. Field measurements ofEaveraged 0·37 mm day−1and ranged from 0·03 (Pleurozium schreberiiin a 77‐year‐old dry stand) to 1·43 mm day−1(Sphagnum ripariumin a 43‐year‐old bog). In the laboratory, moss canopy resistance (which ranged from ∼0 to 1500 s m−1) was constant until a moss water content of ∼6 g g−1and then climbed sharply with further drying; unexpectedly, no difference was observed between the three moss groups (feather mosses, hollow mosses and hummock mosses) tested. Modelled annualEranged from 0·4 mm day−1, in the well‐drained stands, to ∼1 mm day−1in the 43‐year‐old bog. The Penman–Monteith modelling approach used was relatively insensitive to most parameters but only explained 35% of the variability in field measurements. BryophyteEwas greater in bogs than in upland stands, was driven by low‐lying mosses and varied with stand age only in the poorly drained stands; this suggests that bryophytes may provide a buffering effect to fire‐driven changes in tree transpiration.

Published: April 2010

AbstractLand use has a significant impact on spatial patterns of soil moisture, particularly in sensitive and poorly managed regions. This study evaluated the relative importance of soil, vegetation and topography in controlling the spatial moisture patterns in a grazed semi‐arid steppe of Inner Mongolia. Five fields were investigated during 2004–2006: two ungrazed plots since 1979 (UG 79) and 1999 (UG 99); three grazed plots in winter grazed (WG), continuously grazed (CG) and heavily grazed (HG) with 0·5, 1·2 and 2·0 sheep units ha−1 year−1, respectively. The data were analysed using correlation and geostatistical analysis. Results showed that (1) grazing reduced the volumetric moisture contents (0–6 cm) and their spatial heterogeneity; (2) soil moisture patterns had weak to moderate spatial structures and (3) soil and plant properties, especially soil physical properties, were the main factors controlling spatial moisture patterns. Multivariate geostatistics further showed scale‐dependent correlation for these controlling parameters depending on treatments. With increasing grazing intensity, heterogeneity of soil and plant properties decreased from a patchy to a homogeneous distribution. Specifically, the soil and plant properties strongly controlled the variation of soil moisture for UG 99 at short scale (45 m), and for CG and HG at long scale (90 m), however, weakly controlled the variation of soil moisture for UG 79 and WG. Our results have implications for the understanding ecohydrological processes of semi‐arid steppe as well as model parameterization. We suggest that pasture management strongly modified soil moisture patterns, which should be considered in the hydrological models at multiple spatial scales. Copyright © 2010 John Wiley & Sons, Ltd.

Authors: Shi Shenyi , Kong Aiguo , Zhao Xinhua , Zhang Qiying , Shan Yongkui 
Published: April 2010

AbstractFour new task‐specific ionic liquids based on the peroxydisulfate ion were synthesized by the ion exchange method and characterized by FTIR and 1H NMR spectroscopy and elemental analysis. The physicochemical characteristics of these ionic liquids such as density, thermal stability, conductivity, viscosity, and solubility in common solvents have been investigated in detail. The experimental results testify that the ionic liquids prepared show excellent performance as both oxidant and medium in given oxidation reactions of alcohols and thiols under mild reaction conditions.
Atropochiral C,X‐ and C,C‐Chelating Carbon Ligands
Authors: Canac Yves , Chauvin Remi 
Published: April 2010

AbstractIn the realm of atropochiral ligands initiated by the BINOL and BINAP paradigms and extended by modifications of the 1,1′‐binaphthyl backbone and the coordinating heteroatoms (O, P, N, S,..), the emerging domain of the carbon versions serving as spectator ligands in catalysis is reviewed. These atropochiral C,X‐chelating ligands are classified according to their coordinating mode (monodentate or bidentate), to the nature of the auxiliary donor X (a heteroatom or a carbon atom), to the overall charge of the coordinating carbon function (neutral or anionic C‐ligands), and to the hapticity of the coordinating carbon function (η1 for NHCs and ylides, or η2 for alkenes). Emphasis is put on both synthetic aspects and applications in catalysis, and especially in asymmetric catalysis. This survey suggests that the “carbon ligands” should continue to provide surprises not only in coordination chemistry and in stereoselective synthesis and catalysis, but also in fundamental molecular chemistry by pushing farther the stability limits of the metal–ligand interactions, thus reconciliating further the fields of organic and inorganic chemistry.

AbstractMethylene blue (MB) is a typical photosensitizing agent and a DNA hybridization indicator, but its modes of interaction with the DNA molecules are not clearly described, particularly in relation to its electrochemical oxidation signals. To probe the DNA‐MB interactions we have used chromosomal salmon testes and supercoiled plasmid sc pUC19 DNA immobilized on home‐made screen‐printed electrodes (SPEs) and a wide range of MB concentrations, from nano‐ to micromolar. The applicability of the home‐made screen‐printed electrodes used for the DNA‐MB studies were tested using standard calf thymus DNA. Two MB oxidation peak signals: MB(I) at ca. −0.18 V and MB(II) at 0 V vs. Ag/AgCl were detected within ±10–15% standard deviation, signals different from adsorbed MB signal (−0.25 V, pH 4.7). The MB(I) signal, seen when both DNAs were used, showed two plateaus, one at nano‐ and another at micromolar MB concentrations; these were accompanied by the changes in the oxidation signal at 0.98 V, usually attributed to guanine oxidation. In contrast, the MB(II) signal was only seen for salmon testes DNA, indicating various modes of MB interactions with chromosomal and plasmid DNA. In the presence of MB, the guanine related signal (G) at 0.98 V has been amplified significantly (10×), allowing for the identification of the DNAs at low DNA concentrations, the feature particularly useful in the plasmid sc pUC19 detection. The use of another DNA intercalator, riboflavin (RF), aided in the identification of the relation between MB(I), MB(II) and G oxidation signals.
A New Material Based on Nanostructured Prussian Blue Analogue Film Doped with Ce(III) for Development of Hydrogen Peroxide Sensor
Authors: Bian Xiu Zhu , Luo Hong Qun , Li Nian Bing 
Published: April 2010

AbstractPrussian blue analogue nanoparticles doped with Ce(III) (CeHCF) have been synthesized using chitosan (CS) and poly(diallyldimethylammonium chloride) (PDDA) as protective matrix and were cast onto a glassy carbon electrode surface directly. Transmission electron microscopy, UV‐Vis absorption spectroscopy and resonance Rayleigh scattering technique were employed to characterize the PB analogue nanoparticles protected with CS and PDDA. Compared with the bare glassy carbon electrode, the modified electrode exhibited excellent performances for determining H2O2. This work demonstrates the feasibility of the CS‐PDDA‐CeHCF nanoparticles modified glassy carbon electrode for practical sensing applications.

Published: April 2010

AbstractMushroom tissue was immobilized onto plain screen printed electrode (SPE) and multiwalled carbon nanotube (MWCNT) modified SPE (SPE/MWCNT) via bismuth (Bi) deposition. By this way, SPE/Bi/Tissue and SPE/MWCNT/Bi/Tissue biosensors for phenol detection were obtained. UV‐visible spectroscopy and SEM were utilized for explain the immobilization procedure. After optimizing working parameters, both biosensors were compared in terms of analytical characteristics. Linear range of response were found as 5–100 μM for SPE/Bi/Tissue and 2–200 μM for SPE/MWCNT/Bi/Tissue while detection limits were calculated as 0.48 μM and 1.17 μM for SPE/Bi/Tissue and SPE/MWCNT/Bi/Tissue respectively. Developed systems were also applied for phenol detection in synthetically prepared waste water sample and very promising results were obtained.
