“Burnt out” dilated hypertrophic cardiomyopathy causing acute LVAD thrombosis
Authors: Sivathasan Cumaraswamy , Tan Teing E. E. , Sim David , Kerk Ka Lee 
Published: April 2015

Key Clinical MessageCase report illustrates obstruction encountered in a patient with end‐stage dilated hypertrophic cardiomyopathy (HCM) who underwent LVAD implantation. The morphology reversed in early postoperative period to HCM. Pump replacement required coring of the ventricular muscle. Dilated end‐stage hypertrophic cardiomyopathy can revert back to the original morphology on decompression.

Authors: Glaser Andrea M. , Johnston Jennifer H. , Gleason Wallace A. , Rhoads J. Marc 
Published: April 2015

Key Clinical MessageMuscular dystrophy has been traditionally associated with common gastrointestinal symptoms such as reflux, constipation, and dysphasia. In myotonic dystrophy, there are rare reports of chronic intestinal pseudoobstruction (CIPOS). We herein present a case of CIPOS requiring colectomy and with good results.

Authors: Alobeid Bachir , Mears John Gregory , Bhagat Govind 
Published: April 2015

Key Clinical MessageBone marrow involvement by an isolated interstitial lymphoid aggregate exhibiting the pattern and phenotype described for follicular lymphoma in situ (FLIS) has not been reported before.

Function of the Support and Metal Loading on Catalytic Carbon Dioxide Reduction Using Ruthenium Nanoparticles Supported on Carbon Nanofibers
Authors: Roldán Laura , Marco Yanila , García‐Bordejé Enrique 
Published: April 2015

AbstractCatalytic CO2 reduction has been performed using carbon nanofibers or nitrogen‐doped carbon nanofibers as a support for Ru nanoparticles. The catalyst that consists of 5 wt % Ru on nitrogen‐doped carbon nanofibers exhibited the highest conversion at a relatively low temperature, complete selectivity to CH4, and stable catalytic performance. The catalytic performance was substantially superior to catalysts supported on carbon nanotubes and akin to the best metal‐oxide‐supported catalyst in the literature. The characterization of the prepared catalyst by transient experiments (CO2 temperature‐programmed desorption, temperature‐programmed surface reaction, and transient response to CO2 removal) revealed that the catalyst support participates actively in the reaction. The Ru content governed the selectivity, which either favored CO formation for lower Ru contents (0.5–2 wt %) or CH4 formation for 5 wt % Ru loading. The mean Ru particle size determined by TEM was similar for each of the metal loadings. Therefore, the substantially different selectivity patterns cannot be attributed to structure sensitivity. The higher selectivity to CH4 can be explained by the enhanced supply of adsorbed hydrogen to the activated adsorbed CO intermediate, which was demonstrated to be the rate‐determining step.
Structured Ni‐CeO2‐Al2O3/Ni‐Foam Catalyst with Enhanced Heat Transfer for Substitute Natural Gas Production by Syngas Methanation
Authors: Li Yakun , Zhang Qiaofei , Chai Ruijuan , Zhao Guofeng , Liu Ye , Lu Yong 
Published: April 2015

AbstractConcerns about the clean utilization of coal and the development of sustainable energy have provided a particular impetus for the exploration into the production of substitute natural gas (SNG) by syngas methanation in some parts of world. Owing to heat‐transfer limitations, current SNG technology based on a series of fixed‐bed reactors packed with oxide‐supported Ni catalysts suffers from issues such as high costs, low efficiency, and catalyst sintering. We report a monolithic Ni‐Ce‐Al2O3/Ni‐foam catalyst obtainable by modified wet‐chemical etching of Ni foam. Such a catalyst, with significantly enhanced heat transfer, is highly active, highly selective, and very stable for syngas methanation. Computational fluid dynamics calculations and experimental measurements consistently show a large reduction in the “hotspot” temperature in the Ni‐foam‐structured catalyst bed owing to high thermal conductivity. We anticipate that our approach will open a new opportunity for next‐generation SNG plant design.
Enhanced Biocatalytic Performance of Bacterial Laccase from Streptomyces sviceus: Application in the Michael Addition Sequence Towards 3‐Arylated 4‐Oxochromanes
Authors: Suljić Sanel , Mortzfeld Frederik B. , Gunne Matthias , Urlacher Vlada B. , Pietruszka Jörg 
Published: April 2015

AbstractA fast and efficient laccase‐catalysed oxidation/Michael addition sequence is performed using the bacterial laccase Ssl 1 from Streptomyces sviceus under basic conditions to provide a new class of 3‐arylated 4‐oxochromanes. This approach has advantages compared to previous biocatalytic arylation protocols that use fungal laccases under slightly acidic conditions to allow a significant decrease in reaction time with improved yields and maintained regio‐ and diastereoselectivity. Furthermore, a successful diastereoselective, consecutive one‐pot approach with the use of a hydrogenation flow system combined with the laccase‐catalysed arylation was performed. Finally, the general utility of this enzyme as a superior biocatalyst for Michael additions using several nucleophiles was demonstrated. The corresponding starting material was obtained in a straightforward esterification/hydrogenation process with the latter accomplished by using the flow system.
Simple Synthesis of Conformationally Fixed Glycosamine Analogues by Beckmann Rearrangement at the Carbohydrate Ring
Authors: Umbreen Sumaira , Linker Torsten 
Published: April 2015

AbstractConformationally fixed carbohydrate analogues are promising small‐molecule inhibitors for hydrolases like O‐GlcNAcase (OGA); however, their synthesis usually requires many steps. Herein we describe cycloadditions of dichloroketene to various glycals and subsequent Beckmann rearrangements, which offer an easy and stereoselective entry to glycosamine derivatives in good yields. The reactions are applicable for hexoses, pentoses, and disaccharides, and transformations to the corresponding imidates proceed smoothly. First biological tests reveal that such imidates indeed inhibit human OGA.
Preparation and Regioselective Magnesiation or Lithiation of Bis(trimethylsilyl)methyl‐Substituted Heteroaryls for the Generation of Highly Functionalized Heterocycles
Authors: Klatt Thomas , Werner Veronika , Maximova Marina G. , Didier Dorian , Apeloig Yitzhak , Knochel Paul 
Published: April 2015

AbstractA wide range of bis(trimethylsilyl)methyl (BTSM)‐ substituted heteroaryl derivatives has been prepared by using Kumada–Corriu or Negishi cross‐coupling reactions. The regioselective lithiation or magnesiation of these building blocks bearing a bulky BTSM group by using magnesium or lithium 2,2,6,6‐tetramethylpiperidide bases followed by quenching reactions with different electrophiles provides various functionalized N‐, O‐, or S‐heterocycles. Furthermore, the BTSM group can then be converted into formyl, methyl, or styryl groups to give access to a variety of highly functionalized heteroaromatics.
