Published: September 2014

AbstractThe increasing interest of the oncology community in tumour classification and prediction of outcome to targeted therapies has put emphasis on an improved identification of tumour types. Colorectal mucinous adenocarcinoma (MC) is a subtype that is characterized by the presence of abundant extracellular mucin that comprises at least 50% of the tumour volume and is found in 10–15% of colorectal cancer patients. MC development is poorly understood, however, the distinct clinical and pathological presentation of MC suggests a deviant development and molecular background. In this review we identify common molecular and genetic alterations in colorectal MC. MC is characterized by a high rate of MUC2 expression. Mutation rates in the therapeutically important RAS/RAF/MAPK and PI3K/AKT pathways are significantly higher in MC compared with non‐mucinous adenocarcinoma. Furthermore, mucinous adenocarcinoma shows higher rates of microsatellite instability and is more frequently of the CpG island methylator phenotype. Although the majority of MCs arise from the large intestine, this subtype also develops in other organs, such as the stomach, pancreas, biliary tract, ovary, breast and lung. We compared findings from colorectal MC with tumour characteristics of MCs from other organs. In these organs, MCs show different mutation rates in the RAS/RAF/MAPK and PI3K/AKT pathways as well, but a common mucinous pathway cannot be identified. Identification of conditions and molecular aberrations that are associated with MC generates insight into the aetiology of this subtype and improves understanding of resistance to therapies.
Quasi‐Periodic Almost‐Collision Orbits in the Spatial Three‐Body Problem
Authors: Zhao Lei 
Published: September 2014

AbstractIn a system of particles, quasi‐periodic almost‐collision orbits are collisionless orbits along which two bodies become arbitrarily close to each other—the lower limit of their distance is zero but the upper limit is strictly positive—and are quasi‐periodic in a regularized system up to a change of time. Their existence was shown in the restricted planar circular three‐body problem by A.~Chenciner and J. Llibre, and in the planar three‐body problem by J. Féjoz. In the spatial three‐body problem, the existence of a set of positive measure of such orbits was predicted by C. Marchal. In this article, we present a proof of this fact.© 2015 Wiley Periodicals, Inc.
On the Tuning of High‐Resolution NMR Probes
Authors: Pöschko Maria Theresia , Schlagnitweit Judith , Huber Gaspard , Nausner Martin , Horničáková Michaela , Desvaux Hervé , Müller Norbert 
Published: September 2014

AbstractThree optimum conditions for the tuning of NMR probes are compared: the conventional tuning optimum, which is based on radio‐frequency pulse efficiency, the spin noise tuning optimum based on the line shape of the spin noise signal, and the newly introduced frequency shift tuning optimum, which minimizes the frequency pushing effect on strong signals. The latter results if the radiation damping feedback field is not in perfect quadrature to the precessing magnetization. According to the conventional RLC (resistor–inductor–capacitor) resonant circuit model, the optima should be identical, but significant deviations are found experimentally at low temperatures, in particular on cryogenically cooled probes. The existence of different optima with respect to frequency pushing and spin noise line shape has important consequences on the nonlinearity of spin dynamics at high polarization levels and the implementation of experiments on cold probes.
Observation of Unusual Molecular Diffusion Behaviour below the Lower Critical Solution Temperature of Water/2‐Butoxyethanol Mixtures by using Fluorescence Correlation Spectroscopy

Published: September 2014

AbstractThe effect of solute affinity on solute diffusion in binary liquids well below the lower critical solution temperature (LCST) was studied by using fluorescence correlation spectroscopy. We measured the hydrodynamic radii of a hydrophobic and an amphiphilic fluorescent dye under systematic variation of the relative molar fractions of water/2‐butoxyethanol and, for comparison, of water/methanol mixtures, which do not show phase separation. We found that the apparent hydrodynamic radius of the hydrophobic dye almost doubled in water/2‐butoxyethanol, whereas it remained largely unchanged for the amphiphilic dye and in water/methanol mixtures. Our results indicate that the translational diffusion of solutes is influenced by transient local solution structures, even at temperatures well below the LCST. We conclude that, even far below LCST, different solutes can experience different environments in binary liquid mixtures depending on both the solute and solvent properties, all of which impact their reactivity.
Assessment of DNA Binding to Human Rad51 Protein by using Quartz Crystal Microbalance and Atomic Force Microscopy: Effects of ADP and BRC4‐28 Peptide Inhibitor

Published: September 2014

AbstractThe interaction of human Rad51 protein (HsRad51) with single‐stranded deoxyribonucleic acid (ssDNA) was investigated by using quartz crystal microbalance (QCM) monitoring and atomic force microscopy (AFM) visualization. Gold surfaces for QCM and AFM were modified by electrografting of the in situ generated aryldiazonium salt from the sulfanilic acid to obtain the organic layer Au–ArSO3H. The Au–ArSO3H layer was activated by using a solution of PCl5 in CH2Cl2 to give a Au–ArSO2Cl layer. The modified surface was then used to immobilize long ssDNA molecules. The results obtained showed that the presence of adenosine diphosphate promotes the protein autoassociation rather than nucleation around DNA. In addition, when the BRC4‐28 peptide inhibitor was used, both QCM and AFM confirmed the inhibitory effect of BRC4‐28 toward HsRad51 autoassociation. Altogether these results show the suitability of this modified surface to investigate the kinetics and structure of DNA–protein interactions and for the screening of inhibitors.

Published: September 2014

AbstractThe crystal structure of pentamethylbenzene has been obtained for the first time with the use of synchrotron radiation, whilst the low‐energy spectrum of lattice dynamics, dominated by the methyl group torsions, was obtained using inelastic neutron scattering. The effect of symmetry lowering by the removal of a single methyl group relative to hexamethylbenzene has been investigated, including the role that this plays in the charge‐transfer characteristics of complexes formed with tetracyanoethylene.
Flexible Coaxial Nanofibers: A Strategy to Realize Tunable and Enhanced Magnetic‐Luminescent Bifunctionality
Authors: Bi Fei , Dong Xiangting , Wang Jinxian , Liu Guixia 
Published: September 2014

AbstractA new flexible nanostructure of [CoFe2O4/PVP]@[YAG:7 %Tb3+/PVP] magnetic‐luminescent bifunctional coaxial nanofibers is fabricated successfully by electrospinning technology using a homemade coaxial spinneret. The morphologies, structures, and magnetic and luminescent properties of the final products are investigated by modern determination techniques. The results show that the coaxial nanofibers simultaneously provide better magnetic and luminescent properties than CoFe2O4/YAG:7 %Tb3+/PVP composite nanofibers owing to the isolation of the YAG:7 %Tb3+ luminescent nanofibers from the CoFe2O4 magnetic nanofibers. Furthermore, the luminescent characteristics and saturation magnetizations of the coaxial nanofibers can be tuned by adjusting the contents of luminescent and magnetic compounds. The formation mechanism of coaxial nanofibers is also presented. More importantly, the design concept and construction technology are of universal significance for the fabrication of other bifunctional coaxial nanofibers.
Oxygen Permeation Improvement under CO2‐Rich Environments through Catalytic Activation of Hierarchically Structured Perovskite Membranes
Authors: Gaudillere Cyril , Garcia‐Fayos Julio , Serra José M. 
Published: September 2014

AbstractCatalytic activation of a highly porous La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) freeze‐cast asymmetric membrane has been realized by screen‐printing a 30 μm thick LSCF porous layer over the dense top layer of the asymmetric membrane. Membrane activation leads to a noticeable improvement of the oxygen permeation flux (JO2) in the low‐temperature region (<700 °C), at which catalytic gas exchange is the most limiting process. An enhancement of 54 % in JO2 is obtained (JO2=0.17 mL min−1 cm−2) in air at 600 °C thanks to the addition of the LSCF catalytic porous layer, whereas the maximum oxygen permeation is reached when pure oxygen is fed to the membrane at 1000 °C with a high value of 16.3 mL min−1 cm−2. The most appealing effect of the catalytic layer is its protective feature under oxycombustion conditions, that is, under a CO2‐rich atmosphere at high temperature. Indeed, the oxygen permeation drop in the presence of CO2 is significantly lower in the presence of a catalytic porous layer. Interestingly, the full recovery of JO2 flux after CO2 removal in the sweep flux evidences the absence of a carbonation process. Finally, the stability of the functionalized membrane was evaluated at 850 °C and under a 50 % CO2‐containing atmosphere; this revealed a linear degradation rate for oxygen permeation of 4.27×10−2 mL min−1 cm−2 per day.
Symmetries of migration‐related segments of all [001] coincidence site lattice tilt boundaries in (001) projection for all holohedral cubic materials
Authors: Moeck Peter , York Bryant W. , Browning Nigel D. 
Published: September 2014

Utilizing bicrystallography in two dimensions (2D), the symmetries of migration related segments of Coincidence Site Lattice (CSL) boundaries are predicted for projections along their [001] tilt axis in grain boundaries of crystalline materials that possess the holohedral point symmetry of the cubic system (i.e. ). These kinds of “edge‐on” projections are typical for atomic resolution imaging of such tilt boundaries with Transmission Electron Microscopes (TEM). Such images from a recently published aberration‐corrected Z‐contrast scanning TEM investigation [H. Yang et al., Phil. Mag. 93 (2013) 1219] and other studies facilitate the direct visual confirmation of our frieze symmetry predictions with experimental results.
