AbstractMesencephalic astrocyte‐derived neurotrophic factor (MANF) protects dopaminergic neurons from damage. In this study, we used MTT, immunohistochemistry, and TUNEL staining to investigate the protective effect of MANF in SH‐SY5Y cells treated with 6‐OHDA or overexpressed α‐synuclein. Cleaved caspase‐3 levels significantly increased in cells treated with 6‐OHDA or overexpressed α‐synuclein. 6‐OHDA or α‐synuclein overexpression that induced cleaved caspase‐3 levels to increase was reduced by MANF treatment. In addition, MANF treatment upregulated GRP78 expressions in cells treated with 6‐OHDA or overexpressed α‐synuclein, and RNAi knockdown for GRP78 could block the MANF induced cell survival from 6‐OHDA treatment. Furthermore, GRP78 overexpression inhibited 6‐OHDA‐induced apoptosis. Our data suggest that MANF inhibits apoptosis induced by 6‐OHDA and overexpressed α‐synuclein in SH‐SY5Y cells via upregulating GRP78 in the transcriptional pattern.

Published: May 2016

ObjectivesOur aim was to retrospectively evaluate non‐stent graft closure of ascending aortic pseudoaneurysms at our center over a 10‐year period, and describe a combined device occlusion and coil embolization technique.BackgroundAortic pseudoaneurysms (APAs) are a rare complication post cardiothoracic surgery, but can have fatal complications. There is increasing use of percutaneous interventional techniques for occlusion of aortic pseudoaneurysms in patients who are considered unsuitable for surgery. Stent graft deployment may not be possible depending on the specific anatomy and pathology.Methods and ResultsRetrospective evaluation of the catheter laboratory database was performed at our center and anonymized data was obtained for patients who had nonstent endovascular treatment of APAs. Twelve patients were identified with a mean age of 63 ± 16 years. Seven patients had the combined occlusion and embolization technique, only 1/7 (14.3%) died from complications related to APAs. Five patients had occlusion device only, 3/5 (60%) died of complications related to their APA. The mean survival for the patients who had a combination procedure was 33.2±.22.6 months (range, 1 − 60 months), compared to 2.7 ± 2.6 months with device closure only (note 2 patients had short follow up of <3 months).ConclusionsWe evaluate non‐stent graft percutaneous closure of APAs in a high‐risk patient group and provide data on the use of a novel combined occlusion device and coil embolization technique. We feel this is a viable approach to APA closure in this population but this will require larger clinical studies in the future. © 2016 Wiley Periodicals, Inc.

BackgroundPre‐hospital electrocardiograms (ECGs) are believed to reduce time to reperfusion in ST Segment Elevation Myocardial Infarction (STEMI) patients. Little is known of their impact on clinical outcomes in a rural setting. Geisinger regional STEMI network provides percutaneous coronary intervention (PCI) care to over a 100‐mile radius in rural central Pennsylvania.MethodsA retrospective analysis identified 280 consecutive STEMI patients treated with PCI between 1/1/09 and 8/31/11. Comparison between two STEMI groups was performed: 205 patients who were taken by the emergency medical system (EMS) to the nearest hospital (a non‐PCI center), underwent an ECG revealing a STEMI, and were transported immediately to Geisinger Medical Center (GMC) for PCI (transfer group) versus 75 patients in whom a pre‐hospital ECG was obtained and who were transported by EMS directly to Geisinger for PCI, bypassing the nearest hospital that did not perform PCI (the pre‐hospital ECG group).ResultsAnalysis of baseline characteristics revealed that the pre‐hospital ECG cohort was older (65 vs. 60 years); had a higher percentage of previous myocardial infarctions (MI) (28% vs. 15%), heart failure (11% vs. 4%), and prior PCI (23% vs. 13%; p < 0.05 all comparisons). Median time from EMS contact to pre‐hospital ECG in the pre‐hospital ECG group was 5 minutes; from pre‐hospital ECG to the GMC ED was 34 minutes. Median time from first medical contact (EMS contact) to reperfusion (device activation) was 79 versus 157 minutes (P < 0.001), respectively in pre‐hospital ECG vs. transfer groups. Mortality in the two groups at 1 year was 4.1% in the pre‐hospital ECG group versus 8.3% in the transfer group (P‐value = 0.34). After adjusting for the difference in age between the two groups, the 62% reduction in 1 year mortality associated with having obtained a pre‐hospital ECG was still not statistically significant (P‐value = 0.19).ConclusionIn a rural regional STEMI network, pre‐hospital ECGs decreased time from first medical contact to reperfusion by 50% and were associated with an excellent clinical outcome at 1 year. © 2016 Wiley Periodicals, Inc.

Published: May 2016

AbstractTwo isomeric achiral bent‐core liquid crystals involving a 4‐cyanoresorcinol core and containing a carbosilane unit as nanosegregating segment were synthesized and were shown to form ferroelectric liquid‐crystalline phases. Inversion of the direction of one of the COO groups in these molecules leads to a distinct distribution of the electrostatic potential along the surface of the molecule and to a strong change of the molecular dipole moments. Thus, a distinct degree of segregation of the carbosilane units and consequent modification of the phase structure and coherence length of polar order result. For the compound with larger dipole moment (CN1) segregation of the carbosilane units is suppressed, and this compound forms paraelectric SmA and SmC phases; polar order is only achieved after transition to a new LC phase, namely, the ferroelectric leaning phase (SmCLsPS) with the unique feature that tilt direction and polar direction coincide. The isomeric compound CN2 with a smaller dipole moment forms separate layers of the carbosilane groups and shows a randomized polar SmA phase (SmAPAR) and ferroelectric polydomain SmCsPS phases with orthogonal combination of tilt and polar direction and much higher polarizations. Thus, surprisingly, the compound with the smaller molecular dipole moment shows increased polar order in the LC phases. Besides ferroelectricity, mirror‐symmetry breaking with formation of a conglomerate of macroscopic chiral domains was observed in one of the SmC phases of CN1. These investigations contribute to the general understanding of the development of polar order and chirality in soft matter.

Published: May 2016

AbstractIncorporation of silicon‐containing amino acids in peptides is known to endow the peptide with desirable properties such as improved proteolytic stability and increased lipophilicity. In the presented study, we demonstrate that incorporation of β‐silicon‐β3‐amino acids into the antimicrobial peptide alamethicin provides the peptide with improved membrane permeabilizing properties. A robust synthetic procedure for the construction of β‐silicon‐β3‐amino acids was developed and the amino acid analogues were incorporated into alamethicin at different positions of the hydrophobic face of the amphipathic helix by using SPPS. The incorporation was shown to provide up to 20‐fold increase in calcein release as compared with wild‐type alamethicin.

Published: May 2016

AbstractThe twofold glyoxylic Perkin reaction of perylene‐3,9‐diglyoxylic acid with thiophene‐diacetic acid followed by oxidative photocylization and reaction with α‐branched primary alkylamines yields columnar liquid‐crystalline diimides with two sulfur atoms in the condensed arene system. A broad temperature range of the hexagonal columnar mesophase is induced by racemic doubly branched alkyl chains. The HOMO and LUMO energy levels of these thiophene‐derived diimides qualify them as electron donors with respect to perylene diimides.
Selective Activation of Fluoroalkenes with N‐Heterocyclic Carbenes: Synthesis of N‐Heterocyclic Fluoroalkenes and Polyfluoroalkenyl Imidazolium Salts

Published: May 2016

AbstractSelective reactions between nucleophilic N,N′‐diaryl‐heterocyclic carbenes (NHCs) and electrophilic fluorinated alkenes afford NHC fluoroalkenes in high yields. These stable compounds undergo efficient and selective fluoride abstraction with Lewis acids to give polyfluoroalkenyl imidazolium salts. These salts react at Cβ with pyrrolidine to give ammonium fluoride‐substituted salts, which give rise to conjugated imidazolium‐enamine salts through loss of HF. Alternatively, reaction with 4‐(dimethylamino)‐pyridine provides a Cα‐pyridinium‐substituted NHC fluoroalkene. These compounds were studied using multinuclear NMR spectroscopy, mass spectrometry, and X‐ray crystallography. Insight into their electronic structure and reactivity was gained through the use of DFT calculations.
Highly Phosphorescent Crystals of Square‐Planar Platinum Complexes with Chiral Organometallic Linkers: Homochiral versus Heterochiral Arrangements, Induced Circular Dichroism, and TD‐DFT Calculations

Published: May 2016

AbstractA novel class of chiral luminescent square‐planar platinum complexes with a π‐bonded chiral thioquinonoid ligand is described. Remarkably the presence of this chiral organometallic ligand controls the aggregation of this square planar luminophor and imposes a homo‐ or hetero‐chiral arrangement at the supramolecular level, displaying non‐covalent Pt–Pt and π–π interactions. Interestingly these complexes are highly luminescent in the crystalline state and their photophysical properties can be traced to their aggregation in the solid state. A TD‐DFT calculation is obtained to rationalize this unique behavior.
NHC–Copper(I) Halide‐Catalyzed Direct Alkynylation of Trifluoromethyl Ketones on Water

Published: May 2016

AbstractAn efficient and easily scalable NHC–copper(I) halide‐catalyzed addition of terminal alkynes to 1,1,1‐trifluoromethyl ketones, carried out on water for the first time, is reported. A series of addition reactions were performed with as little as 0.1–2.0 mol % of [(NHC)CuX] (X=Cl, Br, I, OAc, OTf) complexes, providing tertiary propargylic trifluoromethyl alcohols in high yields and with excellent chemoselectivity from a broad range of aryl‐ and more challenging alkyl‐substituted trifluoromethyl ketones (TFMKs). DFT calculations were performed to rationalize the correlation between the yield of catalytic alkynylation and the sterics of N‐heterocyclic carbenes (NHCs), expressed as buried volume (%VBur), indicating that steric effects dominate the yield of the reaction. Additional DFT calculations shed some light on the differential reactivity of [(NHC)CuX] complexes in the alkynylation of TFMKs. The first enantioselective version of a direct alkynylation in the presence of C1‐symmetric NHC–copper(I) complexes is also presented.
