Authors: Subbiya Arunajatesan , Padmavathy Kesavaram , Mahalakshmi Krishnan 
Published: March 2013

Purpose Enterococcus faecalis (E. faecalis) is implicated as the common etiological agent of root canal treatment failure. The study was aimed to compare the antibacterial efficacy and to assess the minimum inhibitory concentration (MIC) of 3 gutta-percha solvents - RC Solve, Endosolv-E, and xylene against E. faecalis. Methods Agar well diffusion assay was performed to evaluate the antibacterial efficacy of the guttapercha solvents against E. faecalis (ATCC 29212 and a clinical isolate). The standard drug vancomycin was used as the control. The MIC of the solvents was determined by broth microdilution assay. Two fold serial dilutions of the solvents were prepared and the lowest concentration of the solvent that inhibits visible bacterial growth was recorded as the MIC. Minimum bactericidal concentration (MBC) was determined by plating on Muller Hinton Agar plates and the lowest concentration of the solvent that resulted in 99% reduction of bacterial viability was scored as the MBC. Results The antibacterial activity of RC Solve against E. faecalis was found to be comparable to that of the standard drug-vancomycin. Xylene did not exhibit antibacterial activity while the antibacterial activity of Endosolv-E was lesser than RC Solve. RC Solve recorded lower MIC values against both E. faecalis ATCC29212 and clinical isolate (1:2 and 1:4 dilution) than Endosolv-E (undiluted). RC Solve was found to possess antibacterial activity against E. faecalis even at half the concentration that is routinely being used. Conclusions Within the limitations of the study, we conclude that RC Solve can perform a dual role both as a gutta-percha solvent as well as a microbicide against E. faecalis.

Published: March 2013

Abstract
Chiral iron compounds have been overlooked as potential catalysts in organic synthesis. However, advances in this area within the last decade have revealed only a small part of their potential. There is no doubt that in the near future this field will flourish and further expand to deliver useful processes that will enrich the pool of synthetic methodologies. The aim of this review is to summarize advances in development of enantioselective iron‐complex catalyzed processes and their application in organic synthesis. These processes include oxidative coupling reactions electron‐rich arenes, cycloaddition reactions of unsaturated compounds (e.g. Diels‐Alder reaction, [3+2] and [4‐4] cycloadditions), aldol reactions of silylated enol ethers, carbometallations of cycloalkenes, thia‐ and oxa‐conjugated additions, Friedel‐Crafts reaction, opening of small ring compounds (epoxides), oxidations (epoxidation, dihydroxylation, heteroatom oxidation, and kinetic resolution), reductions (carbonyl group reduction), and other processes (aziridination, carbene insertions).
Multidentate Triphenolsilane‐Based Alkyne Metathesis Catalysts
Authors: Yang Haishen , Liu Zhenning , Zhang Wei 
Published: March 2013

AbstractA series of triphenolsilane‐coordinated molybdenum(VI) propylidyne catalysts has been developed, which are resistant to small alkyne polymerization and compatible with various functional groups (including phenol substrates). The catalysts remain active in solution for days at room temperature (months at −30 °C). The catalysts are also compatible with 5 Å molecular sieves (small alkyne scavengers), and have enabled the homodimerization of small alkyne substrates at 40–70 °C in a closed system, with dimer products being obtained in 76–96% yields. A shape‐persistent aryleneethynylene macrocycle (11) was also prepared on a gram scale with 0.5 mol% catalyst loading, in almost quantitative yield.
Effects of predation risk on the grouping patterns of white‐bellied spider monkeys (Ateles belzebuth belzebuth) in Western Amazonia
Authors: Link Andrés , Di Fiore Anthony 
Published: March 2013

ABSTRACTPredation is proposed to be one of the most important factors influencing the evolution of mammalian societies. Although predation risk is thought to influence both the behavior and grouping patterns of most diurnal primates, evidence supporting this hypothesis is still limited. The spatial and temporal patterns of mineral lick use by one group of white‐bellied spider monkeys (Ateles belzebuth) were evaluated, based on the growing evidence that mineral licks are perceived as areas of relative high predation risk by Neotropical primates. The area immediately surrounding the mineral lick was the most intensively used area within the home range of the study group, particularly by large subgroups of monkeys, and there were differences in mean subgroup size on days of mineral lick visitation versus days without lick visits. Additionally, on days of mineral lick visitation, subgroup size reached its maximum specifically during the period of lick visitation. Finally, on visit days subgroups showed a greater increase in size and higher fusion rates in the 2 hr before arriving at the lick in comparison with matched time windows on non‐visit days. Together, these results provide an example of how primates employ behavioral strategies that might reduce the effects of predation. This study also demonstrates how taxa characterized by a high degree of fission‐fusion dynamics can allow us to test hypotheses regarding the effects of socioecological variables on primate grouping patterns.

Design of decanter in heterogeneous azeotropic distillation column by minimizing Gibbs free energy
Authors: Rahman Imran , Ubaidullah S. , Das Anwesh Kr. 
Published: March 2013

ABSTRACTIn this paper, liquid–liquid equilibrium in decanter of heterogeneous azeotropic distillation is solved by minimizing Gibbs free energy, by using global optimization technique. The azeotropic distillation column is modeled by solving material balance, equilibrium and summation equations, and repulsive particle swarm optimization (RPSO), a stochastic global optimization formalism, is employed to predict stable steady state solution in decanter. To verify the performance of the RPSO algorithm, it is compared with equation solving method for liquid–liquid equilibria by considering two azeotropic systems, namely (1) benzene–ethanol–water and (2) furfural–water. The proposed methodology shows feasibility of the RPSO algorithm in predicting liquid–liquid equilibrium in decanter of heterogeneous azeotropic distillation. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.
Effect of p‐toluenesulfonate on inhibition of overoxidation of polypyrrole
Authors: Kumar Amit , Singh Rajiv K. , Agarwal Khushboo , Singh Hari K. , Srivastava Pankaj , Singh Ramadhar 
Published: March 2013

AbstractElectrochemically synthesized polypyrrole (PPy) films degrade under anodic polarization in aqueous solution. PPy is irreversibly oxidized leading to subsequently to an insulating material. This article highlights the degradation behavior of electrochemically synthesized PPy films using inorganic (perchlorate, ClO4−), organic (p‐toluenesulfonate, pTS−) and mixed (inorganic‐organic, ClO4− + pTS−) anions systems in aqueous solution. The PPy films were subject to overoxidation by means of anodic polarization for a certain period of time and consecutively cyclic voltammetry and electrochemical impedance spectroscopy were employed to investigate the influence of anions used during polymerization on the stability and redox activity of the polymer. The modification in the surface morphology of PPy films due to the application of anodic polarization distinctively shows the effect of degradation at polymer/electrolyte interface. The presence of organic anion in the system (PPy/pTS and PPy/mixed) has shown improved electrochemical activity and is stable to electrochemical degradation for a longer period of time than PPy/ClO4−. © 2013 Wiley Periodicals, Inc.

ObjectiveTransforming growth factor β–inducible gene h3 (βIG‐H3), which is abundantly expressed in rheumatoid synovium, and matrix metalloproteinases (MMP) play important roles in the pathogenesis of rheumatoid arthritis (RA). The aim of this study was to determine the therapeutic efficacy of βIG‐H3–derived peptides using MMP‐1–dependent target tissue delivery in chronic inflammatory arthritis.MethodsPeptides developed from βIG‐H3 derivatives, including the second and fourth YH peptides, the fourth fas‐1 domain, the fourth fas‐1 domain truncated for H1 and H2 sequences (dhfas‐1), and an MMP‐1– cleavable composite peptide (MFK24), were cloned. We confirmed the specificity of MFK24 cleavage by immunoblot analysis after treatment with different proteases.ResultsThe YH18 peptide in the fourth fas‐1 domain of βIG‐H3 was weakly effective in suppressing arthritis severity in mice with collagen‐induced arthritis (CIA). Treatment with higher‐dose dhfas‐1 (30 mg/kg) showed remarkable efficacy, whereas treatment with a lower dose (10 mg/kg) resulted in only partial improvement. MFK24, a composite peptide consisting of dhfas‐1 and RGD peptide linked by MMP‐1 substrate, was cleaved specifically by MMP‐1. The adhesion and migration of NIH3T3 cells mediated by βIG‐H3 were inhibited by MFK24 at a low concentration. MFK24 suppressed the adhesion of NIH3T3 cells more efficiently compared with murine dhfas‐1 (MFK00) or RGD, either alone or in combination. The therapeutic efficacy of MFK24 in mice with CIA was remarkably enhanced, with consistently reduced expression of inflammatory mediators within joint tissue.ConclusionThis proof‐of‐concept study showed that an MMP‐cleavable composite peptide, based on βIG‐H3 derivatives, had markedly improved therapeutic efficacy in chronic inflammatory arthritis, implicating a new expandable strategy for enhancement of the efficacy of 2 different active molecules in RA.

ABSTRACTPogostone is an important constituent of Pogostemon cablin (Blanco) Benth., and possesses various known bioactivities. A rapid, simple and sensitive liquid chromatography tandem mass spectrometry (LC‐MS/MS) method was developed for the analysis of pogostone in rat plasma using chrysophanol as internal standard (IS). The analytes were extracted with methanol and separated using a reversed‐phase YMC‐UltraHT Pro C18 column. Elution was achieved with a mobile phase consisting of methanol–water (75:25, v/v) for 5 min at a flow rate of 400 μL/min. The precursor/product transitions (m/z) under MS/MS detection with negative electrospray ionization (ESI) were 223.0 → 139.0 and 253.1 → 224.9 for pogostone and IS, respectively. The calibration curve was linear over the concentration range 0.05–160 µg/mL (r = 0.9996). The intra‐ and inter‐day accuracy and precision were within ±10%. The validated method was successfully applied to the preclinical pharmacokinetic investigation of pogostone in rats after intravenous (5, 10 and 20 mg/kg) and oral administration (5, 10 and 20 mg/kg). Finally, the oral absolute bioavailability of pogostone in rats was calculated to be 70.39, 78.18 and 83.99% for 5, 10 and 20 mg/kg, respectively. Copyright © 2013 John Wiley & Sons, Ltd.
A Constrained Disorder Refinement: “Reinvestigation of “Single‐Crystal X‐ray Structure of 1,3‐Dimethylcyclobutadiene” by M. Shatruk and I. V. Alabugin”

Published: March 2013

AbstractShatruk and Alabugin propose an alternative structural model for the observed electron density that we have attributed to the photochemical formation of 1,3‐dimethylcyclobutadiene in a protective solid crystalline matrix. The main criticism from Shatruk and Alabugin concerns the modeling of the disorder in the calixarene cavity and in particular the neglect of a residual electron density close to the O1 atom. We published (Chem. Eur. J. 2011, 17, 10021) our opinion concerning this “ignored peak” in the Supporting Information of the paper. The current response to the Correspondence demonstrates that Shatruk and Alabugin have over‐modeled our data by assigning a small electron density peak, which is hardly more than the density corresponding to a hydrogen atom, to an under‐occupied oxygen site, using inappropriate refinement contraints.

Published: March 2013

AbstractThe preparation of chemically modified graphene (CMG) generally involves the reduction of graphite oxide (GO) by using various reducing reagents. Herein, we report a free‐radical‐promoted synthesis of CMG, which does not require any conventional reductant. We demonstrated that the phenyl free radical can efficiently promote the conversion of GO into CMG under mild conditions and produces phenyl‐functionalized CMG. This pseudo‐“reduction” process is attributed to a free‐radical‐mediated elimination of the surface‐attached oxygen‐containing functionalities. This work illustrates a new strategy for preparing CMG that is alternative to the conventional means of chemical reduction. Furthermore, the phenyl‐functionalized graphene shows an excellent performance as an electrode material for lithium‐battery applications.
