Deformation and fracturing using adaptive shape matching with stiffness adjustment
Authors: Ohta Makoto , Kanamori Yoshihiro , Nishita Tomoyuki 
Published: May 2009

AbstractThis paper presents a fast method that computes deformations with fracturing of an object using a hierarchical lattice. Our method allows numerically stable computation based on so‐called shape matching. During the simulation, the deformed shape of the object and the condition of fracturing are used to determine the appropriate detail level in the hierarchy of the lattices. Our method modifies the computation of the stiffness of the object in different levels of the hierarchy so that the stiffness is maintained uniform by introducing a stiffness parameter that does not depend on the hierarchy. By merging the subdivided lattices, our method minimizes the increase of computational cost. Copyright © 2009 John Wiley & Sons, Ltd.

AbstractThyroid stimulating hormone (TSH) binds to a specific TSH receptor (TSHR) which activates adenylate cyclase and increases cAMP levels in thyroidal cells. Recent studies have reported the presence of TSH receptor in several extra‐thyroidal cell types, including erythrocytes. We have previously suggested that TSH is able to influence the erythrocyte Na/K‐ATPase ouabain binding properties through a receptor mediated mechanism. The direct interaction of TSH receptor with the Na/K‐pump and a functional role of TSHR in erythrocytes was not demonstrated. The interaction of TSH receptor with Na/K‐pump and a TSHR functional role are not yet demonstrated in erythrocytes. In this study, we examined the interaction between the two receptors after TSH treatment using immunofluorescence coupled to confocal microscopy and a co‐immunoprecipitation technique. The cAMP dependent signalling after TSH treatment was measured to verify TSHR functionality. We found that TSH receptor and Na/K‐ATPase are localized on the membranes of both erythrocytes and erythrocyte ghosts; TSH receptor responds to TSH treatment by increasing intracellular cAMP levels from two to tenfold. In ghost membranes TSH treatment enhances up to three fold co‐localization of TSHR with Na/K‐ATPase and co‐immunoprecipitation confirms their direct physical interaction. In conclusion our results are compatible with the existence, in erythrocytes, of a functional TSHR that interacts with Na/K‐ATPase after TSH treatment, thus suggesting a novel cell signalling pathway, potentially active in local circulatory control.

Factors Affecting Protein–Glycan Specificity: Effect of Spacers and Incubation Time
Authors: Lewallen Daniel M. , Siler David , Iyer Suri S. 
Published: May 2009

AbstractGlycan binding: We monitored the binding of synthetic glycans to influenza hemagglutinin by using ELISA and surface plasmon resonance, thereby demonstrating that the glycan's presentation influences binding dramatically. Also, the binding observed in static systems was very different from that in dynamic fluid systems. These studies suggest that binding specificities are dependent on glycan structure, valency, presentation, and assay conditions.magnified image
Low‐Temperature Preparation and Characterization of Nanosized Crystalline Anatase Titania with Titanium Tetrachloride and Acetic Anhydride as Materials
Authors: Chen X.‐Q. , Shen W.‐H. 
Published: May 2009

AbstractWhen titanium tetrachloride and acetic anhydride were mixed, an acute reaction occurred immediately. The products, titanyl acetate chloride organic compounds, were studied with FTIR and TGA. The results indicated that they were composed of two dimmers [(CH3CO2TiOCl)2 and (CH3CO2TiCl2)2O] in which a Ti atom combined with acetate in the way of coordinative bonding. In those dimmers, there are frameworks of Ti–O–Ti chemical bridges that are favorable units for forming nanosized crystalline titania. At low temperature (60 °C) and normal pressure, the titanyl acetate chloride organic compounds can hydrolyze to form nanosized crystalline anatase titania globate particles, 5–7 nm in size, which were approved by XRD (x‐ray diffraction), TEM (transmission electron microscope), and LS (laser scattering). And more, the experiments of photocatalytic degradation of the dye rohdamine B revealed the nanosized crystalline anatase titania powders prepared with titanium tetrachloride and acetic anhydride as materials have a good photocatalytic activity.
Origin of the Correlation of the Rate Constant of Substrate Hydroxylation by Nonheme Iron(IV)–oxo Complexes with the Bond‐Dissociation Energy of the CH Bond of the Substrate

Published: May 2009

AbstractA series of hydrogen‐abstraction barriers of a nonheme iron(IV)–oxo oxidant mimicking the active species of taurine/α‐ketoglutarate dioxygenase (TauD) are rationalized by using a valence‐bond curve‐crossing diagram (see figure). It is shown that the barriers correlate with the strength of the CH bond. Furthermore, electronic differences explain the differences between nonheme and heme iron(IV)–oxo hydrogen‐abstraction barriers.magnified imageMononuclear nonheme iron containing systems are versatile and vital oxidants of substrate hydroxylation reactions in many biosystems, whereby the rate constant of hydroxylation correlates with the strength of the CH bond that is broken in the process. The thermodynamic reason behind these correlations, however, has never been established. In this work results of a series of density functional theory calculations of substrate hydroxylation by a mononuclear nonheme iron(IV)–oxo oxidant with a 2 His/1 Asp structural motif analogous to α‐ketoglutarate dependent dioxygenases are presented. The calculations show that these oxidants are very efficient and able to hydroxylate strong CH bonds, whereby the hydrogen abstraction barriers correlate linearly with the strength of the CH bond of the substrate that is broken. These trends have been rationalized using a valence bond (VB) curve‐crossing diagram, which explains the correlation using electron transfer mechanisms in the hydrogen abstraction processes. We also rationalized the subsequent reaction step for radical rebound and show that the barrier is proportional to the electron affinity of the iron(III)–hydroxo intermediate complex. It is shown that nonheme iron(IV)–hydroxo complexes have a larger electron affinity than heme iron(IV)–hydroxo complexes and therefore also experience larger radical rebound barriers, which may have implications for product distributions and rearrangement reactions. Thus, detailed comparisons between heme and nonheme iron(IV)–oxo oxidants reveal the fundamental differences in monoxygenation capabilities of these important classes of oxidants in biosystems and synthetic analogues for the first time and enable us to make predictions of experimental processes.
Switchable Ambient‐Temperature Singlet–Triplet Dual Emission in Nonconjugated Donor–Acceptor Triarylboron–PtII Complexes

Published: May 2009

AbstractDouble the fun! Singlet–triplet dual emission at ambient temperature has been achieved in compounds containing a triarylboron acceptor and an N‐(2′‐pyridyl)‐7‐azaindolyl donor group bridged by a tetrahedral Si linker (see figure). PtII chelation and chelate‐mode switching from N,N to N,C have been found to greatly enhance phosphorescent emission. Furthermore, both singlet and triplet emission bands are responsive to fluoride ions.magnified imageA triarylboron compound Si‐BNPA (1) containing a BMes2 acceptor and an N‐(2′‐pyridyl)‐7‐azaindolyl (NPA) donor linked by a tetrahedral silane group has been synthesised. This molecule displays unusual white singlet–triplet dual emission at 77 K, with an exceptionally long phosphorescent decay time (2.2 s). Fluoride titration experiments established that the singlet and triplet emission peaks are due to acceptor‐based Mes→B charge transfer and donor‐based 3π→π* transitions, respectively. This dual emission was found to be persistent and observable at ambient temperature in its PtII complex [Pt(N,N‐Si‐BNPA)Ph2] (2 a). Furthermore, 2 a was found to undergo intramolecular “roll‐over” CH activation to produce the N,C‐chelate complex [Pt(N,C‐Si‐BNPA)(SMe2)Ph] (2 b). This compound also displays ambient temperature singlet–triplet dual emission, but with a much greater phosphorescent efficiency than 2 a due to the formation of a more stable chelate ring. Addition of fluoride was found to have little impact on the phosphorescent emission of 2 a, but resulted in a large enhancement of the phosphorescent emission intensity of 2 b. To establish the impact of donor–acceptor geometry on this singlet–triplet dual emission, the properties of linearly conjugated donor–acceptor complexes [Pt(N,N‐BNPA)Ph2] (3 a) and [Pt(N,C‐BNPA)Ph2] (3 b) were also examined. Consistent with 2 a and 2 b, the N,C‐chelate complex 3 b has a much higher phosphorescent efficiency than the N,N‐chelate 3 a. Although 3 a and 3 b show bright and fluoride‐switchable phosphorescence at ambient temperature, they are not dual emissive and show only metal‐to‐ligand chage‐transfer‐based phosphorescence. The non‐conjugated donor–acceptor geometry and the overlap of the donor and acceptor singlet and triplet excitation bands in Si‐BNPA and its PtII complexes may thus be the key for achieving singlet–triplet dual emission on two separated chromophores in a single molecule.
