Published: July 2014

ObjectiveThe aim of this study was to determine the frequency‐dependent, spatiotemporal involvement of corticothalamic networks to the generation of absence seizures.MethodsMagnetoencephalography recordings were obtained in 12 subjects (44 seizures) with untreated childhood absence seizures. Time‐frequency analysis of each seizure was performed to determine bandwidths with significant power at ictal onset. Source localization was then completed to determine brain regions contributing to generalized spike and wave discharges seen on electroencephalogram.ResultsSignificant power in the time‐frequency analysis was seen within 1 to 20Hz, 20 to 70Hz, and 70 to 150Hz bandwidths. Source localization revealed that sources localized to the frontal cortex similarly for the low‐ and gamma‐frequency bandwidths, whereas at the low‐frequency bandwidth (3–20Hz) significantly more sources localized to the parietal cortex (odds ratio [OR] = 16.7). Cortical sources within the high‐frequency oscillation (HFO) bandwidth (70–150Hz) localized primarily to the frontal region compared to the parietal (OR = 7.32) or temporal (OR = 2.78) areas.InterpretationNeuromagnetic activity within frontal and parietal cortical regions provides further confirmation of hemodynamic changes reported using functional magnetic resonance imaging that have been associated with absence seizures. The frequency‐dependent nature of these networks has not previously been reported, and the presence of HFOs during absence seizures is a novel finding. Co‐occurring frontal and parietal corticothalamic networks may interact to produce a pathological state that contributes to the generation of spike and wave discharges. The clinical and pathophysiological implications of HFOs within the frontal cortical region are unclear and should be further investigated. Ann Neurol 2014;76:558–567
Highly Electron‐Deficient and Air‐Stable Conjugated Thienylboranes
Authors: Yin Xiaodong , Chen Jiawei , Lalancette Roger A. , Marder Todd B. , Jäkle Frieder 
Published: July 2014

AbstractIntroduced herein is a series of conjugated thienylboranes, which are inert to air and moisture, and even resist acids and strong bases. X‐ray analyses reveal a coplanar arrangement of the thiophene rings, an arrangement which facilitates p–π conjugation through the boron atoms despite the presence of highly bulky 2,4,6‐tri‐tert‐butylphenyl (Mes*) or 2,4,6‐tris(trifluoromethyl)phenyl (FMes) groups. Short B⋅⋅⋅F contacts, which lead to a pseudotrigonal bipyramidal geometry in the FMes species, have been further studied by DFT and AIM analysis. In contrast to the Mes* groups, the highly electron‐withdrawing FMes groups do not diminish the Lewis acidity of boron toward F− anions. These compounds can be lithiated or iodinated under electrophilic conditions without decomposition, thus offering a promising route to larger conjugated structures with electron‐acceptor character.

Published: July 2014

AbstractHydrophobic zeolitic imidazolate frameworks (ZIFs) with the chabazite (CHA) topology are synthesized by incorporating two distinct imidazolate links. Zn(2‐mIm)0.86(bbIm)1.14 (ZIF‐300), Zn(2‐mIm)0.94(cbIm)1.06 (ZIF‐301), and Zn(2‐mIm)0.67(mbIm)1.33 (ZIF‐302), where 2‐mIm=2‐methylimidazolate, bbIm=5(6)‐bromobenzimidazolate, cbIm=5(6)‐chlorobenzimidazolate, and mbIm=5(6)‐methylbenzimidazolate, were prepared by reacting zinc nitrate tetrahydrate and 2‐mIm with the respective bIm link in a mixture of N,N‐dimethylformamide (DMF) and water. Their structures were determined by single‐crystal X‐ray diffraction and their permanent porosity shown. All of these structures are hydrophobic as confirmed by water adsorption isotherms. All three ZIFs are equally effective at the dynamic separation of CO2 from N2 under both dry and humid conditions without any loss of performance over three cycles and can be regenerated simply by using a N2 flow at ambient temperature.
Bonding Nature of Local Structural Motifs in Amorphous GeTe

Published: July 2014

AbstractDespite its simple chemical constitution and unparalleled technological importance, the phase‐change material germanium telluride (GeTe) still poses fundamental questions. In particular, the bonding mechanisms in amorphous GeTe have remained elusive to date, owing to the lack of suitable bond‐analysis tools. Herein, we introduce a bonding indicator for amorphous structures, dubbed “bond‐weighted distribution function” (BWDF), and we apply this method to amorphous GeTe. The results underline a peculiar role of homopolar GeGe bonds, which locally stabilize tetrahedral fragments but not the global network. This atom‐resolved (i.e., chemical) perspective has implications for the stability of amorphous “zero bits” and thus for the technologically relevant resistance‐drift phenomenon.
Synthesis of Bridged Oxafenestranes from Pleuromutilin
Authors: Hicklin Robert W. , López Silva Tania L. , Hergenrother Paul J. 
Published: July 2014

AbstractFenestranes are an intriguing class of highly strained molecules possessing a quaternary carbon with bonds that deviate from the canonical tetrahedral geometry. Herein we report the discovery that the natural product pleuromutilin can be used as a structurally complex starting material for the synthesis of a series of bridged cis,cis,cis,cis‐[4.5.5.5]‐ and cis,cis,cis,cis‐[4.5.7.5]oxafenestranes through a carbocation rearrangement cascade. X‐ray crystallographic analysis of several cis,cis,cis,cis‐[4.5.5.5]oxafenestranes shows a significant planarization of the central tetracoordinate carbon atom and demonstrates the influence of bridgehead substituents and bridging rings on planarity.
Sensitisation of human lung adenocarcinoma A549 cells to radiotherapy by Nimotuzumab is associated with enhanced apoptosis and cell cycle arrest in the G2/M phase

Published: July 2014

AbstractThe epidermal growth factor receptor (EGFR) plays an important role in tumorigenesis and maintenance of cancers, making it a possible therapeutic target for cancer treatment. Nimotuzumab (h‐R3), a humanised monoclonal antibody against EGFR, sensitises human lung adenocarcinoma A549 cells to radiotherapy. We have investigated the underlying molecular mechanism by treating A549 cells with Nimotuzumab (100 μg/mL) alone or in combination with a single dose of 2 Gy irradiation, and analysing apoptosis and cell cycle distribution by flow cytometry. Nimotuzumab significantly enhanced radiation‐induced apoptosis of A549 cells as evidenced by increased cell apoptosis (7.15 ± 0.30%) compared with the control group (1.08 ± 0.25%), Nimotuzumab alone group (4.89 ± 0.30%) and irradiation alone group (5.90 ± 0.15%). Combining Nimotuzumab with irradiation significantly arrested cells in the G2/M phase (43. ± 0.36%) compared radiotherapy alone (18.7 ± 0.35%) and single Nimotuzumab treatment (27.2 ± 0.17%). A combination of Nimotuzumab with radiation increased apoptosis and G2/M phase arrest in human lung adenocarcinoma A549 cells, suggesting potential development of combinatorial therapy of Nimotuzumab with radiotherapy for lung cancer.
Oxidizing Electrode Potentials Decrease Current Production and Coulombic Efficiency through Cytochrome c Inactivation in Shewanella oneidensis MR‐1
Authors: TerAvest Michaela A. , Angenent Largus T. 
Published: July 2014

AbstractPrevious transcriptomic profiling of Shewanella oneidensis MR‐1 had suggested that electron transfer to an anode in a bioelectrochemical system may induce a general stress response (similar to a heat‐shock response) and/or an increase in protein turnover rates. Analysis of this microbe grown with a wide variety of electron acceptors also indicated that protein turnover may be related to the redox potential of the terminal electron acceptor. To investigate whether electrodes can induce stress and increase protein turnover, S. oneidensis was grown at potentiostatically poised electrodes at five redox potentials versus the standard hydrogen electrode (SHE) between −3 and +797 mVSHE. Subsequently, current production, coulombic efficiency, and transcription levels of marker genes for general stress and protein turnover were measured. Maximal current production was found at +397 mVSHE, and maximal coulombic efficiency was observed at +197 mVSHE. Both values decreased at more positive (oxidizing) potentials, that is, extracellular electron transfer of S. oneidensis is optimal at moderate electrode potentials. In contrast to previous findings, transcript measurements of a stress‐marker gene indicate that extracellular electron transfer does not increase general stress in comparison with aerobic respiration. Although overall protein turnover is not related to electrode potential, increased expression of a protease suggests that protein degradation increases at oxidizing electrode potentials. Cyclic voltammetry revealed decreased activity of c‐type cytochromes at the higher potentials, which indicates that oxidizing electrodes directly damage electron‐transfer proteins at the electrode surface.

Published: July 2014

AbstractBis‐β‐ketoimine ligands of the form [(CH2)n{N(H)C(Me)CHC(Me)O}2] (LnH2, n=2, 3 and 4) were employed in the formation of a range of gallium complexes [Ga(Ln)X] (X=Cl, Me, H), which were characterised by NMR spectroscopy, mass spectrometry and single‐crystal X‐ray diffraction analysis. The β‐ketoimine ligands have also been used for the stabilisation of rare gallium hydride species [Ga(Ln)H] (n=2 (7); n=3 (8)), which have been structurally characterised for the first time, confirming the formation of five‐coordinate, monomeric species. The stability of these hydrides has been probed through thermal analysis, revealing stability at temperatures in excess of 200 °C. The efficacy of all the gallium β‐ketoiminate complexes as molecular precursors for the deposition of gallium oxide thin films by chemical vapour deposition (CVD) has been investigated through thermogravimetric analysis and deposition studies, with the best results being found for a bimetallic gallium methyl complex [L3{GaMe2}2] (5) and the hydride [Ga(L3)H] (8). The resulting films (F5 and F8, respectively) were amorphous as‐deposited and thus were characterised primarily by XPS, EDXA and SEM techniques, which showed the formation of stoichiometric (F5) and oxygen‐deficient (F8) Ga2O3 thin films.
