AbstractObjectives: To determine the occurrence of in‐hospital complications after transcatheter aortic valve implantation (TAVI) according to the Valve Academic Research Consortium (VARC) criteria in addition to the length of stay (LOS). Background: The absence of uniformity in endpoint definitions challenges the comparison between previously reported major adverse cerebro‐ and cardiovascular event rates after TAVI. To address this, in 2009, the VARC was established aiming to provide standardized endpoint definitions for TAVI clinical trials. Methods: Between November 2005 and September 2010, we prospectively enrolled 150 consecutive patients who underwent TAVI with the Medtronic CoreValve System in our institution. Complications, prosthetic valve associated endpoints, and therapy‐specific endpoints were defined according to the definitions provided by the VARC. Results: The mean age (±SD) was 81 (±7) years and 55% were female. Thirty‐day or in‐hospital mortality was 11%, and the 30‐day combined safety endpoint was 22%. Seventy‐six patients (51%) had ≥1 cardiovascular and/or noncardiovascular complication of whom 16 also underwent a new permanent pacemaker implantation (PPI). In the 74 patients with uneventful TAVI, 12 patients (8%) underwent PPI. TAVI was truly uneventful in 62 patients (41%). Bleeding complications were observed most frequently (31%), followed by acute kidney injury (18%), vascular complications (16%), and stroke/TIA (11%). The median LOS in patients with a complicated and a truly uncomplicated TAVI was 14.0 (8.0–20.5) and 8.0 (7.0–10.8) days, respectively (P < 0.001). Conclusion: TAVI was associated with ≥1 cardiovascular and/or noncardiovascular event in 51% of the patients; new PPI was needed in another 8%, and TAVI was truly uncomplicated in 41%. Complications and need for new PPI significantly prolonged LOS. © 2011 Wiley‐Liss, Inc.

Published: May 2011

AbstractWe have investigated conformational switching dynamics of meso‐heptakis(pentafluorophenyl) [32]heptaphyrin(1.1.1.1.1.1.1) in various solvents using steady‐state, time‐resolved, and temperature‐dependent spectroscopy. Absorption and fluorescence spectra of [32]heptaphyrin are quite sensitive to solvent environments. In nonpolar toluene, the antiaromatic figure‐of‐eight conformation is dominant, as seen in the X‐ray crystallography, based on broad and weak absorption bands without any fluorescence and moderate paratropic ring current. On the other hand, a well‐resolved sharp absorption spectrum, strong fluorescence, and diatropic ring current in the 1H NMR spectrum in slightly polar THF indicate that most of [32]heptaphyrin molecules take significantly distorted Möbius conformation with aromatic character. By using transient absorption (TA) spectroscopy, the lowest singlet excited‐state lifetimes have been revealed to decay biexponentially with the time constants of 5 and 65 ps for figure‐of‐eight and Möbius conformations, respectively. Based on these results along with vertical excitation energy calculations, we are able to assign two conformers as Hückel antiaromatic and Möbius aromatic species, respectively; it shoulf be noted that the aromaticity/antiaromaticity does not change with temperature variation. Interestingly, in moderately polar solvent, ethyl ether, we find out that these two conformational isomers coexist with a dynamic equilibrium, as revealed by excitation‐wavelength‐dependent TA, temperature‐dependent absorption and 1H NMR spectra. Through our findings, we have demonstrated that the conformational switching dynamics between Hückel antiaromatic and Möbius aromatic conformers in [32]heptaphyrin(1.1.1.1.1.1.1) are strongly affected by solvent medium as well as temperature.
Conformationally Controlled Electron Delocalization in n‐Type Rods: Synthesis, Structure, and Optical, Electrochemical, and Spectroelectrochemical Properties of Dicyanocyclophanes

Published: May 2011

AbstractA series of dicyanobiphenylcyclophanes 1–6 with various π‐backbone conformations and characteristic n‐type semiconductor properties is presented. Their synthesis, optical, structural, electrochemical, spectroelectrochemical, and packing properties are investigated. The X‐ray crystal structures of all n‐type rods allow the systematic correlation of structural features with physical properties. In addition, the results are supported by quantum mechanical calculations based on density functional theory. A two‐step reduction process is observed for all n‐type rods, in which the first step is reversible. The potential gap between the reduction processes depends linearly on the cos2 value of the torsion angle φ between the π‐systems. Similarly, optical absorption spectroscopy shows that the vertical excitation energy of the conjugation band correlates with the cos2 value of the torsion angle φ. These correlations demonstrate that the fixed intramolecular torsion angle φ is the dominant factor determining the extent of electron delocalization in these model compounds, and that the angle φ measured in the solid‐state structure is a good proxy for the molecular conformation in solution. Spectroelectrochemical investigations demonstrate that conformational rigidity is maintained even in the radical anion form. In particular, the absorption bands corresponding to the SOMO–LUMO+i transitions are shifted bathochromically, whereas the absorption bands corresponding to the HOMO–SOMO transition are shifted hypsochromically with increasing torsion angle φ.
Rationalization and In Vitro Modeling of the Chemical Mechanisms of the Enzymatic Oxidation of Phenolic Compounds in Planta: From Flavonols and Stilbenoids to Lignins

Published: May 2011

AbstractEnzymatic oxidation of phenolic compounds is a widespread phenomenon in plants. It is responsible for the formation of many oligomers and polymers, which are generally described as the result of a combinatorial coupling of the different radicals formed through oxidation of the phenol group and delocalization of the radical. We focused our interest on several phenolic compounds that are present in plants and known to form, under enzymatic oxidation, oligomers with different type of linkages between monomers. To explain this diversity of inter‐monomer linkages and their variation according to the experimental procedure used for the enzymatic oxidation, we report an alternative mechanistic pathway involving dismutation of the radicals, leading to the formation of carbocations which, thereafter, react with nucleophilic species present in the medium. This alternative pathway allows the understanding of peculiar linkages between monomeric units in the oligomer and offers new insights for understanding the formation of phenolic biopolymers in plants.
Fast and High‐Resolution Stereochemical Analysis by Nonuniform Sampling and Covariance Processing of Anisotropic Natural Abundance 2D 2H NMR Datasets

Published: May 2011

AbstractNatural abundance deuterium (NAD) 2D NMR spectroscopy using chiral or achiral liquid crystals is an efficient analytical tool for the stereochemical analysis of enantio‐ or diastereomers by the virtue of proton‐to‐deuterium substitution. In particular, it allows the measurement of enantiopurity of organic synthetic molecules or the determination of the natural isotopic 1H/2H fractionation in biological molecules, such as fatty acid methyl esters (FAME). So far, the NAD 2D spectra of solutes were acquired by using uniform sampling (US) and processed by conventional 2D Fourier transform (FT), which could result in long measurement times for medium‐sized analytes or low solute concentrations. Herein, we demonstrate that this conventional approach can be advantageously replaced by nonuniform sampling (NUS) processed by covariance (Cov) transform. This original spectral reconstruction provides a significant enhancement of spectral resolution, as well as a reduction of measurement times. The application of Cov to NUS data has required the introduction of a regularization procedure in the time domain for the indirect dimension. The analytical potential of combining Cov and NUS is demonstrated by measuring the enantiomeric excess of a scalemic mixture of 2‐ethyloxirane and by determining the diastereomeric excess of methyl vernoleate, a natural FAME. These two organic compounds were aligned in a polypeptide (poly(γ‐benzyl‐L‐glutamate)) mesophase. In the case of NAD 2D NMR spectroscopy, we show that Cov and NUS methods allow a decrease in measurement time by a factor of two compared with Cov applied to US data and a factor of four compared with FT applied to US data.
Tunable Morphology of 2D Honeycomb‐Patterned Films and the Hydrophobicity of a Ferrocenyl‐Based Oligomer

Published: May 2011

AbstractHoneycomb‐patterned polymer films with tunable pore size and regularity of ordered two‐ or three‐dimensional hexagonal arrays have met with widespread interest in recent years in different areas, for instance as separation and superhydrophobic materials. Herein, 2D honeycomb‐patterned films of amphiphilic ferrocenyl‐based oligomer with cholesterol as side chains were prepared by the breath‐figure method on solid surfaces and their surface‐wetting behavior were tested. These films can be simply prepared by spreading a mixture of polymer and organic solvents on a solid surface under moist airflow and at an air/water interface without any extra moist airflow. An ordered 2D hexagonal array of pores with monodisperse size distribution can be obtained over a large area by changing various influencing factors, including humidity, wet volume, concentration, selective solvent, and spreading method, which provides a facile route to regulate the morphology of patterned porous films. The surface‐wetting behavior indicates that a higher hydrophobicity of the ferrocenyl‐based oligomer honeycomb films can be obtained by modulating the pore size and regularity. It is expected that this could promote the potential application of ordered porous polymer films in hydrophobic materials and biochemistry.
