Published: March 2016

ObjectivesTo describe medium‐ to long‐term follow‐up of patients undergoing device closure of patent foramen ovale (PFO) for stroke or transient ischemic attack (TIA).BackgroundTranscatheter device closure of PFO continues to be used for secondary prevention of cryptogenic stroke or TIA, but data are lacking regarding long‐term outcomes.MethodsWe reviewed the Mayo Clinic Rochester PFO database for patients who underwent device closure of PFO for secondary prevention of stroke/TIA from December 2001 to June 2012. Demographic, clinical, procedural, and follow‐up data were reviewed. Recurrence rate of stroke/TIA were calculated. Data were analyzed to identify risk factors of recurrent neurologic events.ResultsSeven hundred and thirty patients (mean age 53 years; 40% female) were included in our study. Most patients (72%) had cryptogenic stroke as their qualifying event for PFO closure. There were no procedure‐related deaths or strokes. The most commonly used device was the Amplatzer Septal Occluder (82%). Median follow‐up was 6 years. A 3.9% of patients had documented residual right‐to‐left shunting at last echocardiogram. Recurrent stroke and/or TIA were reported in 45 patients, (6.3% of patients with follow‐up data). Patients who experienced recurrent stroke/TIA were older and had a higher rate of diabetes and hypertension than those who did not. The presence of residual shunt did not correlate with risk of recurrent events.ConclusionsDevice closure of PFO can be performed safely with very good long‐term resolution of atrial shunting. Recurrent neurologic events after PFO closure may reflect additional comorbid risk factors unrelated to the potential for paradoxical embolism. © 2016 Wiley Periodicals, Inc.
Transmembrane Protein‐Based Electrochemical Biosensor for Adiponectin Hormone Quantification
Authors: Brazaca Laís C. , Janegitz Bruno C. , Cancino‐Bernardi Juliana , Zucolotto Valtencir 
Published: March 2016

AbstractDecreased adiponectin hormone secretion occurs 10–20 years before chronic hyperglycemia, and is a great indicator of further development of type 2 diabetes. Here, we developed an electrochemical biosensor for adiponectin quantification based on specific transmembrane receptors (AdipoR1 and AdipoR2). Under optimized conditions, cyclic‐voltammetry‐based adiponectin biosensors displayed linearity (R2=0.992) in a wide range of concentrations (0.025–0.75 μmol l−1), including typical human serum levels, with a detection limit of 7.0 nmol L−1 and reproducibility of 1.7 %, n=3. Electrochemical impedance spectroscopy results showed a similar behavior, with a linear increase in charge‐transfer resistance (R2=0.971) from 0.025 to 1.00 μmol l−1, a detection limit of 7.0 nmol L−1, and reproducibility of 5.6 %, n=3. Furthermore, the analytical results obtained by using the biosensor in human serum samples were in agreement with those obtained by using the enzyme‐linked immunosorbent assay (ELISA) at a 95 % confidence level. It is expected the proposed device increases the number of predictive type 2 diabetes diagnostics, promoting early treatment and patient awareness about the precautions to be taken.
CoMn Layered Double Hydroxides/Carbon Nanotubes Architectures as High‐Performance Electrocatalysts for the Oxygen Evolution Reaction
Authors: Liu Zhibin , Yu Chang , Han Xiaotong , Yang Juan , Zhao Changtai , Huang Huawei , Qiu Jieshan 
Published: March 2016

AbstractHigh‐efficiency, earth‐abundant oxygen evolution reaction (OER) catalysts are highly desired and required for the half reaction of water splitting. Herein, an integrated system composed of CoMn layered double hydroxides (CoMn‐LDH) and carbon nanotubes (CNTs) were configured for the OER. Ultrathin CoMn‐LDH nanoplates can grow and assemble in situ on conducting CNT frameworks to form the CoMn‐LDH/CNT nanoarchitectures. The CNT frameworks provide conducting channels for fast charge transfer, whereas CoMn‐LDH features highly active sites and is capable of catalyzing the OER process. Benefiting from functional integration of the highly active CoMn‐LDH nanoplates and the strong coupling effects between ultrathin nanoplates and conducting CNT frameworks, the as‐made CoMn‐LDH/CNT nanohybrids achieve excellent OER performance with a small overpotential (355 mV at 10 mA cm−2), low Tafel slope (45 mV dec−1), and prominent electrochemical durability.
The Utilization of Amide Groups To Expand and Functionalize Metal–Organic Frameworks Simultaneously

Published: March 2016

AbstractA new stepwise ligand‐elongation strategy by amide spacers is utilized to prepare isoreticularly high‐porous metal–organic frameworks (MOFs), namely, quasi‐mesoporous [Cu2(PDBAD)(H2O)]n (H4PDBAD=5,5′‐((4,4′‐((pyridine‐3,5‐dicarbonyl)bis(azanediyl))bis(benzoyl))bis(azanediyl))diisophthalic acid; NJU‐Bai22: NJU‐Bai for Nanjing University Bai's group), and mesoporous [Cu2(PABAD)(H2O)]n (H4PABAD=5,5′‐((4,4′‐((4,4′‐((pyridine‐3,5‐dicarbonyl)bis(azanediyl))bis(benzoyl))bis (azanediyl))bis(benzoyl))bis(azanediyl))diisophthalic acid; NJU‐Bai23). Compared with the prototypical MOF of [Cu2(PDAD)(H2O)]n (H4PDAD=5,5′‐(pyridine‐3,5‐dicarbonyl)bis(azanediyl)diisophthalic acid; NJU‐Bai21, also termed as PCN‐124), both MOFs exhibit almost the same CO2 adsorption enthalpy and CO2 selectivity values, and better capacity for CO2 storage under high pressure; these results make them promising candidate materials for CO2 capture and sequestration. Interestingly, this new method, in comparison with traditional strategies of using phenyl or triple‐bond spacers, is easier and cheaper, resulting in a better ability to retain high CO2 affinity and selectivity in MOFs with large pores and high CO2 storage capacity. Additionally, it may lead to the high thermal stability of the MOFs and also their tolerance to water, which is related to the balance between the density of functional groups and pore sizes. Therefore, this strategy could provide new opportunities to explore more functionalized mesoporous MOFs with high performance.
Asymmetric Synthesis and Binding Study of New Long‐Chain HPA‐12 Analogues as Potent Ligands of the Ceramide Transfer Protein CERT

Published: March 2016

AbstractA series of 12 analogues of the Cer transfer protein (CERT) antagonist HPA‐12 with long aliphatic chains were prepared as their (1R,3S)‐syn and (1R,3R)‐anti stereoisomers from pivotal chiral oxoamino acids. The enantioselective access to these intermediates as well as their ensuing transformation relied on a practical crystallization‐induced asymmetric transformation (CIAT) process. Sonogashira coupling followed by triple bond reduction and thiophene ring hydrodesulfurization (HDS) into the corresponding alkane moieties was then implemented to complete the synthetic routes delivering the targeted HPA‐12 analogues in concise 4‐ to 6‐step reaction sequences. Ten compounds were evaluated regarding their ability to bind to the CERT START domain by using the recently developed time‐resolved FRET‐based homogeneous (HTR‐FRET) binding assay. The introduction of a lipophilic appendage on the phenyl moiety led to an overall 10‐ to 1000‐fold enhancement of the protein binding, with the highest effect being observed for a n‐hexyl residue in the meta position. The importance of the phenyl ring for the activity was indicated by the reduced potency of the 3‐deoxyphytoceramide aliphatic analogues. The 1,3‐syn stereoisomers were systematically more potent than their 1,3‐anti analogues. In silico studies were used to rationalized these trends, leading to a model of protein recognition coherent with the stronger binding of (1R,3S)‐syn HPAs.
Molecular Gold Wire from Mixed‐Valent AuI/III Complexes
Authors: Böge Matthias , Heck Jürgen 
Published: March 2016

AbstractCrystals of mixed‐valent Au complexes have been grown from solutions of cyclohexanecarbonitrile and a stoichiometric amount of gold(I) and gold(III) chloride. The purely obtained compound was characterized as bis(cyclohexanecarbonitrile)gold(I) tetrachloridoaurate(III). The crystal packing of the mixed valent Au(I/III) compound demonstrates a columnar arrangement of the gold(I) and gold(III) atoms. The new structure displays the shortest unsupported gold(I)–gold(III) interactions with the sub‐van der Waals distance of 324–325 pm, which is assumed as an aurophilic bonding interaction.
