Carotid stenting versus endarterectomy for the treatment of carotid artery stenosis: Contemporary results from a large single center study
Authors: Meller Stephanie M. , Salim Al‐Damluji Mohammed , Gutierrez Alejandra , Stilp Erik , Mena‐Hurtado Carlos 
Published: May 2016

ObjectiveTo compare the complication rates associated with carotid endarterectomy (CEA) versus carotid artery stenting (CAS).BackgroundCarotid stenosis is a well‐known cause of stroke and increased mortality. The safety of carotid revascularization may be related to symptom status, medical comorbidities, use of embolic protection devices, as well as operator experience and these factors may vary across patient populations within a single operating center.MethodsWe retrospectively analyzed patients with carotid artery stenosis admitted to our hospital for carotid revascularization between January 1, 2007 and December 1, 2013. The primary end point was a composite endpoint of periprocedural death, stroke, and myocardial infarction (MI).ResultsOf the 718 patients admitted for carotid revascularization 525 (73.1%) underwent CEA and 193 (26.9%) underwent CAS. Both groups demonstrated similar rates of the composite endpoint, MI, and death; the stenting group demonstrated a higher rate of stroke (4.2% vs. 1.3%; P = 0.020). Adjusting for baseline medical comorbidities and symptom status mitigated this difference (P = 0.091 and 0.113, respectively). When stratified by department performing CAS, there was a significant difference in the occurrence of stroke (P = 0.033), which likewise disappeared in the multivariate regression analysis.ConclusionThe risk of the composite endpoint did not differ significantly between those undergoing CAS versus CEA. The stenting group demonstrated a higher rate of periprocedural stroke, which was also apparent when patients were stratified by stenting department. These differences were likely driven by variation in baseline medical comorbidities and symptom status. © 2016 Wiley Periodicals, Inc.
Multistage Countercurrent Crystallization for the Separation of Solid Solutions
Authors: Münzberg Stephan , Lorenz Heike , Seidel‐Morgenstern Andreas 
Published: May 2016

AbstractWhile one crystallization step can be sufficient to provide pure components in case of eutectic systems, multistage operation is required to resolve solid solutions. A recently published equilibrium stage model was adopted here and generalized to simplify the description of the corresponding solid‐liquid equilibrium (SLE). The equilibria of the system potassium sulfate/ammonium sulfate/water were studied at different temperatures. The existence of a controversially discussed miscibility gap below 25 °C could not be confirmed. Using the equilibrium stage model and the studied specific SLE data, process variants considering different evaporation strategies were simulated.
A Catalyst‐Enabled Diastereodivergent Aza‐Diels–Alder Reaction: Complementarity of N‐Heterocyclic Carbenes and Chiral Amines
Authors: Rong Zi‐Qiang , Wang Min , Chow Chi Hao Eugene , Zhao Yu 
Published: May 2016

AbstractHighly efficient and diastereodivergent aza‐Diels–Alder reactions have been developed to access either diastereomeric series of benzofuran‐fused δ‐lactams and dihydropyridines in nearly perfect stereoselectivity (d.r. >20:1, >99 % ee for all examples). The complementarity of N‐heterocyclic carbene and chiral amine as the catalyst was demonstrated for the first time, together with an excellent level of catalytic efficiency (1 mol % loading).

Efficient Trapping of 1,2‐Cyclohexadienes with 1,3‐Dipoles
Authors: Lofstrand Verner A. , West Frederick G. 
Published: May 2016

Abstract1,2‐Cyclohexadienes are transient intermediates that undergo rapid dimerization and intermolecular trapping with activated olefins and heteroatomic nucleophiles. Fluoride‐mediated desilylative elimination of readily accessible 6‐silylcyclohexene‐1‐triflates allows the mild, chemoselective, and functional‐group tolerant generation of cyclic allene intermediates, which undergo efficient trapping reactions with stable 1,3‐dipoles. The reactions proceed with high levels of both regio‐ and diastereoselectivity. The reaction of cyclic allenes with azides is accompanied by the facile loss of dinitrogen, resulting in the formation of tetrahydroindoles or polycylic aziridines depending on the azide employed.
