Capillary circular dichroism
Authors: Waldron Daniel E. , Marrington Rachel , Grant Marcus C. , Hicks Matthew R. , Rodger Alison 
Published: June 2010

AbstractCircular dichroism (CD) has become an increasingly important tool in the study of biological molecules as it enables structural information to be obtained nondestructively on solution‐phase samples. However, sample requirements for CD are often seen as being too high with protein backbone measurements in standard cuvettes typically requiring ∼100–300 μL of 0.1 mg/ml protein. To address this issue, we have designed a new form of CD sample holder, which reduces the sample requirements of the technique by two orders of magnitude, with a sample requirement of less than 3 μl. This sample saving has been achieved through the use of extruded quartz capillaries, the sample being held within the internal diameter of the quartz capillary through capillary action. The extruded quartz capillaries exhibit remarkably little birefringence, although still transmitting high energy UV circularly polarized light. The optics associated with capillaries were investigated. A configuration has been adopted with the light beam of the spectrophotometer being focused in front of the front face of the capillary using a biconvex lens and advantage being taken of the additional focusing effect of the capillary itself. The focusing is vital to the low wavelength performance of the cell, where we have acquired reliable data down to 180 nm using a Jasco J‐815 spectrophotometer. The system performance was validated with Na[Co(EDDS)].H2O (EDDS = N,N‐ethylenediaminedisuccinic acid), concanavalin A, lysozyme, and progesterone. Chirality, 2010. © 2010 Wiley‐Liss, Inc.
Organische Solarzellen. Energie der Zukunft
Authors: Wöhrle Dieter , Hild Olaf R. 
Published: June 2010

AbstractPhotovoltaischen Solarzellen kommt bei der zunehmenden Nutzung erneuerbarer Energien durch das hohe Angebot an solarer Einstrahlung besondere Bedeutung zu. Daher wird neben den bewährten anorganischen Solarzellen auch an der Entwicklung von preiswerteren Solarzellen gearbeitet, die organische Materialien als aktive Verbindungen für die Energieumwandlung verwenden. Der Artikel beschreibt Aufbau und Funktionsweise von Farbstoffsensibilisierungs‐Solarzellen und organischen Feststoff‐Solarzellen. Für Vergleiche und zum Verständnis dieser Zellen ist es notwendig, auch einige Aspekte der Photosynthese und der anorganischen Solarzellen kurz zu behandeln. Damit wird insgesamt ein Einblick in solare Energieumwandlungssysteme unter Berücksichtigung aktueller Entwicklungen gegeben.
Hoch stereoselektive Wittig‐analoge Olefinierungsreaktion
Authors: Doye Sven 
Published: June 2010

AbstractDie Wittig‐Reaktion ist eine der wichtigsten präparativen Methoden zur stereoselektiven Herstellung von 1, 2‐disubstituierten Alkenen, wobei als Ausgangsmaterialien Aldehyde und meist in situ generierte Phosphonium‐Ylide zum Einsatz kommen. Die Stereoselektivität der Reaktion, also die Frage, ob sich das E‐ oder das Z‐Alken bildet, wird hierbei in der Regel durch die Art des Phosphonium‐Ylids bestimmt.
Zucker an Kieselsäure präbiotisch

Published: June 2010

AbstractDa logischerweise niemand zugeschaut hat, als Gott die Welt erschuf, sind wir auf Vermutungen, Extrapolationen und Modelle angewiesen, wie denn wohl am wahrscheinlichsten die ersten “primordialen” (und optisch aktiven!) organischen (also Kohlenstoff‐haltigen) Biomoleküle entstanden, aus denen die Lebewesen heute aufgebaut sind. Man ist sich nicht einmal gewiss, wie die geochemischen Verhältnisse auf Erden “damals” waren.

Published: June 2010

AbstractEs sind keine versponnenen Wissenschaftler, die sich mit Spinnenseide befassen, denn das Produkt der achtbeinigen Tierchen ist weit mehr als ein wissenschaftlich hoch interessantes Naturprodukt. Wegen seiner beeindruckenden Materialeigenschaften könnte es den Weg zu neuen Kunstfasern weisen – wenn man denn genau wüsste, wie die Spinne ihren Faden eigentlich spinnt. Der Antwort auf diese Frage sind Wissenschaftler der Technischen Universität München und der Universität Bayreuth nun einen großen Schritt näher gekommen.
A data‐centered collaboration portal to support global carbon‐flux analysis
Authors: Agarwal Deborah A. , Humphrey Marty , Beekwilder Norm F. , Jackson Keith R. , Goode Monte M. , van Ingen Catharine 
Published: June 2010

AbstractCarbon‐climate, like other environmental sciences, has been changing. Large‐scale synthesis studies are becoming more common. These synthesis studies are often conducted by science teams that are geographically distributed and on data sets that are global in scale. A broad array of collaboration and data analytics tools are now available that could support these science teams. However, building tools that scientists actually use is difficult. Also, moving scientists from an informal collaboration structure to one mediated by technology often exposes inconsistencies in the understanding of the rules of engagement between collaborators. We have developed a scientific collaboration portal, calledfluxdata.org, which serves the community of scientists providing and analyzing the global FLUXNET carbon‐flux synthesis data set. The key things we learned or re‐learned during our portal development include: minimize the barrier to entry, provide features on a just‐in‐time basis, development of requirements is an on‐going process, provide incentives to change leaders and leverage the opportunity they represent, automate as much as possible, and you can only learn how to make it better if people depend on it enough to give you feedback. In addition, we also learned that splitting the portal roles between scientists and computer scientists improved user adoption and trust. The fluxdata.org portal has now been in operation for ∼2 years and has become central to the FLUXNET synthesis efforts. Published in 2010 by John Wiley & Sons, Ltd.
Almost Ideal 1D Water Diffusion in Imogolite Nanotubes Evidenced by NMR Relaxometry
Authors: Belorizky Elie , Fries Pascal H. , Guillermo Armel , Poncelet Olivier 
Published: June 2010

AbstractThe longitudinal proton relaxation ratesR1of water diffusing inside synthetic aluminium silicate imogolite nanotubes are measured by fast field‐cycling NMR for frequencies between 0.02 and 35 MHz at 25, 37 and 50 °C. We give analytical expressions of the dominant intermolecular dipolar spin–spin contribution toR1and to the transverse relaxation rateR2. A remarkable variation ofR1by more than two orders of magnitude is observed and shown to be close to the theoretical law, inversely proportional to the square root of the resonance frequency, which is characteristic of perfect molecular 1D diffusion. The physics of diffusion is discussed.
Type D personality and posttraumatic stress disorder in victims of violence: a cross‐sectional exploration
Authors: Kunst M. J. J. , Bogaerts S. , Winkel F. W. 
Published: June 2010

AbstractThe current study explored the relationship between type D personality and posttraumatic stress disorder (PTSD) among victims of violence (n = 189). The basic premise underlying the type D concept is that it is not the experience of negative emotions per se that renders individuals at risk of maladjustment in the face of adversity, but the way they are dealt with. Particularly the combination of high negative affectivity and social inhibition (i.e., the non‐expression of emotions and inhibition of behaviours in social interactions) is assumed to be maladaptive. It was hypothesized that a high score on negative affectivity (i.e., above a pre‐determined cut‐off score) would only contribute to PTSD in the presence of a high score on social inhibition (also above a pre‐determined cut‐off score). Univariate results indicated that type D subjects (type Ds) reported higher PTSD symptom levels than those characterized by high negative affectivity/low social inhibition or low negative affectivity. Type Ds more often suffered from probable PTSD than non‐type Ds. In multivariate analyses, type D personality was associated with an increased risk of probable PTSD above and beyond background variables, while high negative affectivity/low social inhibition was not. Results were discussed in light of victim support practices and study limitations. Copyright © 2010 John Wiley & Sons, Ltd.Key Practitioner Message:• Victims of violence with type D personality are more prone to report symptom levels that indicate diagnosis of PTSD.• Victim support interventions should be tailored to help victims with type D personality to maintain their existing social networks, for example through support groups only accessible to victims and close relatives or friends.

Published: June 2010

AbstractBackground:Minimal residual disease (MRD) is a powerful prognostic indicator in childhood acute lymphoblastic leukemia (ALL). Multiparametric flow cytometry (FC) is a rapid and sensitive methodology for detection of MRD, applicable for most patients and is being incorporated in multicenter treatment protocols. The influence of different techniques and of individual interpretation of data on the interlaboratory variability in FC‐MRD determinations has not been described.Methods:We compared FC‐MRD of identical bone marrow samples processed as either Ficoll separated mononuclear cells or lyse and wash nucleated cells (NC) in two central laboratories of a national multicenter childhood ALL study. A total of 290 samples at diagnosis and 494 follow‐up samples (Day‐15 n = 261; Day‐33 n = 233) were analyzed. A group of 52 paired list mode data (LMD) of D‐15 and D‐33 samples was blindly reanalyzed by both laboratories.Results:Pearson correlations for all samples of D‐15 (n = 261) and D‐33 (n = 233) were 0.875 and 0.82, respectively (P < 0.001), being lower for T‐ALL 0.716 and 0.719, respectively. Quantitative concordance defined as less than 0.5 log difference in MRD measured by the two methodologies was 80.8% at D‐15 but only in 57.9% at D‐33. Reanalysis of LMD revealed that data interpretation explained half of the discordance.Conclusions:FC‐MRD analysis of childhood ALL is a robust method during the earliest phases of induction therapy in a multicentric setting. Standardization of data analysis could improve about half of the discordance between different technical approaches. © 2010 International Clinical Cytometry Society

AbstractThe cover image of this issue consists of confocal images of cytomegalovirus‐infected human fibroblast cells stained for HLA‐A2/pp65 complexes, taken from Makler et al. (pp. 1552–1565). In this article, the authors use antibodies that mimic TCR specificity to directly visualize the dynamics of antigen presentation in these cells. The authors show that, following infection, large intracellular pools of HLA‐A2/pp65 complexes are localized to the Golgi. Interestingly, these large pools are sequestered inside infected cells and only a small portion of them are exported to the cell surface.
2,4,6‐Triacetylphlorogucinol as Threefold Symmetric Bridging Ligand: Synthesis, Structure and Magnetic Properties of the Copper Complex
Authors: Spielberg Eike T. , Plass Winfried 
Published: June 2010

AbstractIt is shown that 2,4,6‐triacetylphlorogucinol (H3tapg) can be utilized as C3‐symmetric tritopic bridging ligand, that can be regarded as an annulated threefold acetylacetonate. Together with 2‐[bis(2‐hydroxyethyl)amino]ethylamine (H2bhea) as capping ligand the corresponding trinuclear copper complex [Cu3(tapg)(H2bhea)3](ClO4)3 has been synthesized as the first example. The compound crystallizes in the trigonal space group R3c with the complex cation located on a threefold rotation axis. Magnetic measurements reveal a ferromagnetic coupling between the copper centers, which are transmitted through the bridging tapg3– ligand by a spin‐polarization mechanism.

Asymmetric Aza‐Morita–Baylis–Hillman Reactions of Alkyl Vinyl Ketones with N‐Protected Imines or In Situ Generated N‐Protected Imines
Authors: Guan Xiao‐Yang , Wei Yin , Shi Min 
Published: June 2010

AbstractDABCO‐catalyzed aza‐MBH reactions of N‐Boc imines with MVK and EVK have been thoroughly investigated in the paper. The asymmetric version of this aza‐MBH reaction was also systematically investigated by using a chiral amine or a chiral phosphane catalyst. It was found that most of the N‐protected imines are suitable substrates under the mild reaction conditions and are able to give the corresponding adducts in moderate yields with high ee values. The TQO‐ or LB1‐catalyzed aza‐MBH reactions of N‐protected α‐amidoalkyl phenyl sulfones or α‐amidoalkyl p‐tolyl sulfones with MVK could be well conducted, which provides a facile and direct route to obtain highly enantioselective aza‐MBH adducts. The Boc protecting group of the aza‐MBH product could be easily removed under acidic conditions to give the corresponding α‐methylene‐β‐amino ketone or α‐methylene‐β‐amino alcohol derivatives in good yields.

Authors: Wu Shuoguo , Liu Jinping , Bai Xue , Tan Wenguang 
Published: June 2010

AbstractThe cellulose acetate covered Prussian blue modified glassy carbon electrode (GCE/PB/CA) was fabricated as a novel hydrogen peroxide sensor. It was shown by scanning electron microscope (SEM) and atomic force microscope (AFM) that Prussian blue was covered and protected by cellulose acetate perfectly. The modified electrode showed a good electrocatalytic activity for H2O2 reduction in neutral aqueous solution. H2O2 was detected amperometrically in 0.05 mol/L phosphate buffer solutions (pH 7.0, containing 0.1 mol/L KCl as supporting electrolyte) at an applied potential of −0.2 V (vs. SCE). The response current was proportional to the concentration of H2O2 in the range of 1.0×10−5 mol/L to 2.5×10−4 mol/L with the detection limit of 2.2×10−6 mol/L at a signal to noise ratio 3.
Construction of a Novel Glucose Biosensor Based on Covalent Immobilization of Glucose Oxidase on Poly(glycidyl methacrylate‐co‐vinylferrocene)
Authors: Şenel Mehmet , Abasıyanık M. Fatih 
Published: June 2010

AbstractA novel glucose biosensor was constructed via direct covalent attachment of glucose oxidase onto epoxy group containing polymeric electron transfer mediator, Poly(glycidyl methacrylate‐co‐vinylferrocene). A copolymer of glycidyl methacrylate (GMA) and vinylferrocene (VFc) with different molar ratios has been prepared by free radical copolymerization. These copolymers have been utilized as polymeric mediators for amperometric glucose sensing. The catalytic electrochemistry of the enzyme electrode with the copolymer was investigated. Copolymer acts as an electron transfer mediator between the redox center of Glucose oxidase (GOx) and the electrode. The stability, reusability, pH and temperature response of the biosensor as well as its kinetic parameter have also been studied.
Neural correlates of pantomiming familiar and unfamiliar tools: Action semantics versus mechanical problem solving?
Authors: Vingerhoets Guy , Vandekerckhove Elisabeth , Honoré Pieterjan , Vandemaele Pieter , Achten Eric 
Published: June 2010

AbstractThis study aims to reveal the neural correlates of planning and executing tool use pantomimes and explores the brain's response to pantomiming the use of unfamiliar tools. Sixteen right‐handed volunteers planned and executed pantomimes of equally graspable familiar and unfamiliar tools while undergoing fMRI. During the planning of these pantomimes, we found bilateral temporo‐occipital and predominantly left hemispheric frontal and parietal activation. The execution of the pantomimes produced additional activation in frontal and sensorimotor regions. In the left posterior parietal region both familiar and unfamiliar tool pantomimes elicit peak activity in the anterior portion of the lateral bank of the intraparietal sulcus—A region associated with the representation of action goals. The cerebral activation during these pantomimes is remarkably similar for familiar and unfamiliar tools, and direct comparisons revealed only few differences. First, the left cuneus is significantly active during the planning of pantomimes of unfamiliar tools, reflecting increased visual processing of the novel objects. Second, executing (but not planning) familiar tool pantomimes showed significant activation on the convex portion of the inferior parietal lobule, a region believed to serve as a repository for skilled object‐related gestures. Given the striking similarity in brain activation while pantomiming familiar and unfamiliar tools, we argue that normal subjects use both action semantics and function from structure inferences simultaneously and interactively to give rise to flexible object‐to‐goal directed behavior.
