Background: We previously reported that the 1‐year survival‐free from target lesion revascularization was 97.4% in patients with chronic total occlusion (CTO) treated with sirolimus‐eluting stents (SES). There are currently no long‐term results of the efficacy of SES in this subset of lesions. We assessed the 3‐year clinical outcomes of 147 patients with CTO treated with either SES or bare metal stents (BMS). Methods and Results: A total of 147 (BMS = 71, SES = 76) patients were included. Four patients died in the BMS group while five patients died in the SES group, P = 0.8; two myocardial infarctions occurred in both groups, P = 0.9; and target vessel revascularization was performed in nine patients in the BMS and seven in the SES group, P = 0.5. The cumulative event‐free survival of MACE was 81.7% in BMS group and 84.2% in SES group, P = 0.7. Two patients of the SES group had a coronary aneurism at 3‐year angiographic follow‐up. Conclusions: The use of SES was no longer associated with significantly lower rates of target vessel revascularization and major adverse cardiac events in patients with CTOs after 3 years of follow‐up compared with BMSs. © 2007 Wiley‐Liss, Inc.
Theoretical Study of Catalytic Efficiency of a Diels–Alderase Catalytic Antibody: An Indirect Effect Produced During the Maturation Process

Published: October 2007

The Diels–Alder reaction is one of the most important and versatile transformations available to organic chemists for the construction of complex natural products, therapeutics agents, and synthetic materials. Given the lack of efficient enzymes capable of catalyzing this kind of reaction, it is of interest to ask whether a biological catalyst could be designed from an antibody‐combining site. In the present work, a theoretical study of the different behavior of a germline catalytic antibody (CA) and its matured form, 39 A‐11, that catalyze a Diels–Alder reaction has been carried out. A free‐energy perturbation technique based on a hybrid quantum‐mechanics/molecular‐mechanics scheme, together with internal energy minimizations, has allowed free‐energy profiles to be obtained for both CAs. The profiles show a smaller barrier for the matured form, which is in agreement with the experimental observation. Free‐energy profiles were obtained with this methodology, thereby avoiding the much more demanding two‐dimensional calculations of the energy surfaces that are normally required to study this kind of reaction. Structural analysis and energy evaluations of substrate–protein interactions have been performed from averaged structures, which allows understanding of how the single mutations carried out during the maturation process can be responsible for the observed fourfold enhancement of the catalytic rate constant. The conclusion is that the mutation effect in this studied germline CA produces a complex indirect effect through coupled movements of the backbone of the protein and the substrate.

The chiral resolution of pesticides on amylose‐tris(3,5‐dimethylphenylcarbamate) CSP by HPLC and the enantiomeric identification by circular dichroism
Authors: Wang Peng , Liu Donghui , Jiang Shuren , Xu Yangguang , Gu Xu , Zhou Zhiqiang
Published: October 2007

Amylose‐tris(3,5‐dimethylphenylcarbamate) (ADMPC) was synthesized and coated on γ‐aminopropylsilica to prepare a chiral stationary phase (CSP). The chiral resolutions of seven pesticide enantiomers including fenoxaprop‐ethyl, quizalofop‐ethyl, lactofen, metalaxyl, benalaxyl, hexythiazox and fluroxypyr‐meptyl on the CSP by high‐performance liquid chromatography were performed. Mobile phase was n‐hexane and isopropanol with a flow rate of 1.0 ml/min. The influences of isopropanol content in the mobile phase and temperature on the resolutions were investigated. Under the optimized conditions the enantiomers could obtain complete resolutions except that metalaxyl got partial resolution. Decreasing the content of isopropanol increased the retention and the resolutions. Temperature was an important chromatographic parameter for optimization, and the results showed that low temperature was not always good to the resolutions. The enantiomers were identified by a circular dichroism (CD) detector which could provide the CD signals [(+) or (−)] and the CD spectra in the range of 220–420 nm by online scanning.

Chiral 1,1′‐binaphthyl‐2,2′‐dithiol‐stabilized gold clusters: Size separation and optical activity in the UV–vis
Authors: Gautier Cyrille , Taras Rossana , Gladiali Serafino , Bürgi Thomas
Published: October 2007

Gold particles covered with 1,1′‐binaphthyl‐2,2′‐dithiol (BINAS) were prepared. Using size exclusion chromatography, it was possible for the first time to separate the sample into fractions with different sizes and colors. Transmission electron microscopy shows that the particles are very small, in the order of 1 nm or slightly above. The absorption spectra of the separated samples show rich structure. The particles show size‐dependent optical activity in metal‐based electronic transitions. The shape of both the absorption and circular dichroism spectra of one of the smallest fractions exhibits similarities with the spectra reported for Au11 covered by 2,2′‐bis(diphenylphosphino)‐1,1′‐biphenyl although the spectra are shifted to shorter wavelengths in the case of the dithiol. The anisotropy factors, Δϵ/ϵ of these particles are as large as 4 × 10−3, which is larger than the values reported for gold particles stabilized by phosphines and water‐soluble thiols. This indicates that BINAS is particularly well‐suited to impart chirality on to gold particles. Chirality, 2008. © 2007 Wiley‐Liss, Inc.

BACKGROUND.

The purpose of this study was to identify problems related to long‐term quality of life (QOL) and sexual function in cervical cancer survivors.

METHODS.

The authors enrolled 860 women (median time since diagnosis, 5.86 years) with a history of cervical cancer (stage I to IVa) who had been treated at any of 6 hospitals from 1983 through 2004 and 494 control subjects selected randomly from a representative sample of Korean women. Subjects filled out a questionnaire that included the European Organization for Research and Treatment of Cancer (EORTC) QLQ‐C30, its Cervical Cancer Module, and additional sexual function items.

RESULTS.

Cervical cancer survivors had clinically significant worse problems with social functioning, constipation, diarrhea, and difficulties with their finances than controls (P < .01). Survivors also reported more severe lymphedema and menopausal symptoms and worse body image, sexual and/or vaginal functioning, and sexual worry (P < .01). Anxiety about sexual performance was more problematic in survivors than in controls (P < .01), as was dyspareunia for women who received radiotherapy (P < .01).

CONCLUSIONS.

These findings can increase the awareness of healthcare providers to the potential need for counseling and other interventions among women who have been successfully treated for cervical cancer and could help them improve their impaired QOL. Cancer 2007. © 2007 American Cancer Society.
KOALA: a co‐allocating grid scheduler
Authors: Mohamed Hashim , Epema Dick
Published: October 2007

In multicluster systems, and more generally in grids, jobs may require co‐allocation, that is, the simultaneous or coordinated access of single applications to resources of possibly multiple types in multiple locations managed by different resource managers. Co‐allocation presents new challenges to resource management in grids, such as locating sufficient resources in geographically distributed sites, allocating and managing resources in multiple, possibly heterogeneous sites for single applications, and coordinating the execution of single jobs at multiple sites. Moreover, as single jobs now may have to rely on multiple resource managers, co‐allocation introduces reliability problems. In this paper, we present the design and implementation of a co‐allocating grid scheduler named KOALA that meets these co‐allocation challenges. In addition, we report on the results of an analysis of the performance in our multicluster testbed of the co‐allocation policies built into KOALA. We also include the results of a performance and reliability test of KOALA while our testbed was unstable. Copyright © 2007 John Wiley & Sons, Ltd.
Hierarchical Structure‐Within‐Structure Morphologies in A2‐star‐(B‐alt‐C) Molecules
Authors: Huang Ching‐I , Chen Chih‐Ming
Published: October 2007

We employ dissipative particle dynamics (DPD) to examine the self‐assembly behavior of A2‐star‐(B‐alt‐C) molecules. We successfully observe various types of hierarchical structure‐within‐structures, such as A‐formed spheres in the matrix formed by B and C alternating layers, hexagonally packed A‐formed cylinders in the matrix with B and C segregated layers, B and C alternating layers‐within‐lamellae, coaxial B and C alternating domains within hexagonally packed BC‐formed cylinders in the A‐matrix, and co‐centric BC‐alternating domains within BC‐formed spheres in the A‐matrix, by increasing the A composition. Generally speaking, the small length‐scale B and C segregated domains are in parallel to the large length‐scale structures. This hierarchical periodicity along the same axis as well as the various characteristic structures, that the A2‐star‐(B‐alt‐C) copolymers display, are quite different from those in A‐block‐(B‐graft‐C) coil‐comb copolymers. Moreover, it is interesting to find that when the copolymer chain length increases, though the hierarchical structure type is maintained, the number of small length‐scale lamellae that can form within the large length‐scale structure increases. These hierarchical structures under various compositions are reported theoretically for the first time in the copolymer systems consisting of the alternating blocks, and are in good agreement with the most recent experimental work by Matsushita and co‐workers (Macromolecules 2007, 40, 4023).
Different Protonation Equilibria of 4‐Methylimidazole and Acetic Acid
Authors: Gu Wei , Helms Volkhard
Published: October 2007

Dynamic protonation equilibria in water of one 4‐methylimidazole molecule as well as for pairs and groups consisting of 4‐methylimidazole, acetic acid and bridging water molecules are studied using Q‐HOP molecular dynamics simulation. We find a qualitatively different protonation behavior of 4‐methylimidazole compared to that of acetic acid. On one hand, deprotonated, neutral 4‐methylimidazole cannot as easily attract a freely diffusing extra proton from solution. Once the proton is bound, however, it remains tightly bound on a time scale of tens of nanoseconds. In a linear chain composed of acetic acid, a separating water molecule and 4‐methylimidazole, an excess proton is equally shared between 4‐methylimidazole and water. When a water molecule is linearly placed between two acetic acid molecules, the excess proton is always found on the central water. On the other hand, an excess proton in a 4‐methylimidazole‐water‐4‐methylimidazole chain is always localized on one of the two 4‐methylimidazoles. These findings are of interest to the discussion of proton transfer along chains of amino acids and water molecules in biomolecules.
Orientation and Arrangement of Octaruthenium Supramolecules with Alkyl Chains on Graphite

Published: October 2007

The self‐assemblies of octaruthenium grid‐type supramolecules, {[Ru2(CO)4(NH2C16H33)2](μ‐O2CCO2)}4, on highly oriented pyrolytic graphite (HOPG) in air and in 1‐phenyloctane were studied by scanning tunneling microscopy (STM). The surface supramolecules are arranged into rows in which the metal cores are linearly packed and the alkyl chains are parallel to the surface. With the aid of theoretical calculations in the framework of density functional theory, the electronic origin of the tunneling in the measured STM images is discussed. (© Wiley‐VCH Verlag GmbH & Co.

Aldehyde N,N‐Dialkylhydrazones as Neutral Acyl Anion Equivalents: Umpolung of the Imine Reactivity
Authors: Brehme Rainer , Enders Dieter , Fernandez Rosario , Lassaletta José M.
Published: October 2007

The isoelectronic replacement of the α‐carbon of enamines by nitrogen leads to the corresponding hydrazones, and thus, they can be termed “aza‐enamines”. Hence, aldehyde N,N‐dialkylhydrazones enable analogous electrophilic substitutions at the imine carbon that corresponds to the β‐carbon of enamines. In addition, after hydrolysis of the product hydrazones to the parent ketones or aldehydes, these reactions constitute an umpolung of the classical carbonyl reactivity and overall a nucleophilic acylation or formylation. This review covers the aza‐enamine chemistry from its very beginning in the late 1960s up to this year. In the first part, reactions of aromatic, aliphatic, and heterocyclic aldehyde N,N‐dialkylhydrazones with highly reactive substrates such as the Vilsmeier and Mannich reagents, sulfonyl isocyanates, perfluoroacetic anhydride, and inorganic electrophiles such as halogens and phosphorus tribromide are described. The hydrazones of α,β‐unsaturated aldehydes react as vinylogous aza‐enamines at the terminal carbon providing unsaturated aldehydes. As electron‐rich dienes and dienophiles, they also form Diels–Alder adducts and thus interesting N‐heterocycles. The second part covers carbon–carbon bond formations of the sterically less‐demanding formaldehyde N,N‐dialkylhydrazones with synthetically very useful electrophiles such as various Michael acceptors and carbonyl compounds. Formaldehyde SAMP‐hydrazone and related derivatives generally give excellent asymmetric inductions. Finally, first organocatalytic versions of the aza‐enamine chemistry are presented. In summary, the rich chemistry of aldehyde N,N‐dialkylhydrazones as neutral acyl anion, formyl anion, and cyanide equivalents is demonstrated. (© Wiley‐VCH Verlag GmbH & Co.

Stereoselective Formation of a Chiral Ether by Intramolecular O–H Insertion Reaction of a Metal Carbenoid Generated from Diazoacetoacetate
Authors: Im Chun Young , Okuyama Tadashi , Sugimura Takashi
Published: October 2007

Intermolecular O–H insertion reactions of rhodium carbenoids generated from chiral diazoacetoacetates are less efficient and less stereoselective than the reactions of those generated from the corresponding phenyldiazoacetates. Nevertheless, when the diazoacetoacetate is connected to a phenolic moiety through a 2,4‐pentanediol tether, the carbenoid generated shows a high potential in both efficiency and stereoselectivity during the intramolecular O–H insertion reaction to give a cyclic ether in up to 88 % diastereomeric excess (de) in quantitative yield. The de value depends on the structure of the tether, but is independent of the catalyst employed. The isomerization of the cyclic ether has been studied under the conditions of equilibrium and kinetic protonation of the corresponding enolate. The similarity between the de values obtained by insertion and those obtained under equilibrium suggests that the rhodium catalyst is eliminated during the early stages of the O–H insertion reaction and that proton transfer, which determines thestereoselectivity, occurs after the elimination of the rhodium metal, independent of the stereochemistry of the initial addition.(© Wiley‐VCH Verlag GmbH & Co.
