Fingerprinting DNA Oxidation Processes: IR Characterization of the 5‐Methyl‐2′‐Deoxycytidine Radical Cation
Authors: Bucher Dominik B. , Pilles Bert M. , Pfaffeneder Toni , Carell Thomas , Zinth Wolfgang 
Published: January 2014

AbstractMethylated cytidine plays an important role as an epigenetic signal in gene regulation. Its oxidation products are assumed to be involved in active demethylation processes but also in damaging DNA. Here, we report the photochemical production of the 5‐methyl‐2′‐deoxycytidine radical cation via a two‐photon ionization process. The radical cation is detected by time‐resolved IR spectroscopy and identified by band assignment using density functional theory calculations. Two final oxidation products are characterized with liquid chromatography coupled to mass spectrometry.
Assembly of TiO2‐on‐Cu2O Nanocubes with Narrow‐Band Cu2O‐Induced Visible‐Light‐Enhanced Photocatalytic Activity
Authors: Liu Jiali , Wen Ming , Chen Hanxing , Li Jing , Wu Qing‐Sheng 
Published: January 2014

AbstractNewly designed TiO2‐on‐Cu2O nanocubes have been constructed as visible‐light‐driven photocatalysts with high efficiency by means of a facile self‐assembly approach at room temperature. In the resultant TiO2‐on‐Cu2O nanocubes, the TiO2 nanoparticles with a diameter of 6–8 nm show a well‐monodispersed distribution of the 200–300 nm‐sized Cu2O single‐crystal nanocubes, which can form sub‐monolayer, monolayer, and multilayer coverage through controlling the ratio of the two phases. In particular, the coupling of the wide‐bandgap semiconductor TiO2 with narrow‐bandgap Cu2O can lead to the markedly enhanced high visible‐light photocatalytic activity in the TiO2‐on‐Cu2O nanocomposite systems toward the photodegradation of rhodamine B, which is induced by the bandgap‐adjusting effect. This promising self‐assembly route can be extended to the preparation of other nanocomposite materials.

Published: January 2014

AbstractA detailed kinetic study of the reaction of aquacobalamin [H2OCbl(III)] with hydrogen sulfide in water at pH 1 to 10 was carried out using conventional spectrophotometric, stopped‐flow, and high‐pressure stopped‐flow techniques. The reaction proceeds in three steps: formation of the complex between aquacobalamin and hydrogen sulfide, inner‐sphere electron transfer, and addition of a second molecule of hydrogen sulfide to the reduced cobalamin. Kinetic parameters for the different reaction steps of the studied process were determined. The final products of the reaction between aquacobalamin and hydrogen sulfide were found to depend on pH. The main reaction product is five‐coordinate base‐on reduced cobalamin(II) [B12r, Cbl(II)] in alkaline medium and six‐coordinate cobalamin(II) with the anion‐radical SSH2– in acidic medium.
Tuning the Optical Properties of 1,1′‐Biphospholes by Chemical Alterations of the P–P Bridge
Authors: Arkhypchuk Anna I. , Orthaber Andreas , Ott Sascha 
Published: January 2014

Abstract2,5‐Di(1‐naphthyl)‐1‐phenylphosphole (2) was prepared from phenylphosphine and dinaphthylbutadiyne in 70 % yield, and oxidized to its oxide 3. Treatment of 2 with a solution of potassium naphthalide results in selective formation of phospholide anion 4, which can be oxidized with iodine to afford biphosphole 5. The crystal structure of 5 exhibits an unusual s‐trans conformation across the P–P bridge that is most stabilized by π–π stacking of the naphthyl substituents. Biphosphole 5 can be oxidized to its mono‐oxidized 6 and dioxide 7. Generally, all phosphole oxidations lead to decreased pyramidalization of the P centres and, consequently, to significantly redshifted lowest‐energy absorption maxima. Mono‐oxidized biphosphole 6, which consists of an ordinary phosphole and an electron‐deficient oxidized phosphole, features a unique low‐energy optical transition (shoulder at 430 nm), which is tentatively assigned to a charge‐transfer transition. The UV/Vis spectrum of dioxide 7 lacks this transition. At the same time, the emission maximum of 7 is bathochromically shifted by 80 nm relative to that of 5.

AbstractAn efficient synthesis of substituted indolizine and its benzo derivatives, pyrrolo[1,2‐a]quinolines and pyrrolo[2,1‐a]isoquinolines, by the reaction of allenyl ketones with α‐bromo carbonyl compounds and pyridines (quinoline or isoquinoline) under mild conditions without an added oxidant other than molecular oxygen from air was developed. Notably, allenyl ketones with or without a substituent attached to the internal position of the allene moiety afforded indolizine derivatives with different substitution patterns.
Tin Microspheres Grown on Carbon Cloth as Binder‐Free Integrated Anode for High Capacity Lithium Storage
Authors: Song Weifeng , Hou Xiaojuan , Wang Xianfu , Liu Bin , Chen Di , Shen Guozhen 
Published: January 2014

AbstractHigh quality Sn microspheres were successfully synthesized on carbon cloth by a one‐step chemical vapor deposition method. Used as a binder‐free anode material for lithium‐ion batteries, the three‐dimensional integrated anode based on as‐grown Sn microspheres on carbon cloth exhibited excellent performance for lithium storage with high capacity of more than 800 mAh g−1 even after 75 cycles, as well as good cycling stability and rate capability. The good electrochemical performance can be ascribed to the microsized spheres, which have the appropriate size and structural symmetry to counteract the force of lithium insertion/extraction process, as well as to the binder‐free integrated anode structure, which enhances the electrical conductivity and enlarges the available reaction surface. This simple strategy has the potential for large‐scale production of other electrode materials for high performances in lithium‐ion batteries.

Published: January 2014

Objective/HypothesisThis study examined correlations between surgical recommendations based on either drug‐induced sleep endoscopy (DISE) or common awake examination methods in patients with obstructive sleep apnea syndrome (OSAS).Study DesignProspective, blinded, clinical trial at a university hospital.MethodsAn otorhinolaryngologist designed surgical plans for patients with OSAS after clinical examination, lateral cephalometry, the Müller maneuver, and Friedman staging. A second otorhinolaryngologist blinded to the previous plans made surgical recommendations after DISE. A third person tested agreement between the two sets of plans using Cohen's kappa statistic and the chi‐squared test.ResultsOne hundred and sixty‐two patients (15 females, 147 males) completed the protocol. Good correlation was observed between DISE and Friedman staging regarding recommendations for isolated oropharyngeal or multilevel surgery (kappa = 0.61). Correlations between DISE and clinical examination, lateral cephalometry, and the Müller maneuver regarding surgical procedures on specific structures contributing to upper airway obstruction ranged from fair for velum/tonsil surgery (k = 0.41–0.60) to poor (k = 0.01–0.20) for tongue‐base, lateral pharyngeal wall, and epiglottal surgery. The most informative value was DISE versus clinical evaluation, lateral cephalometry, and the Müller maneuver, which changed surgical recommendations concerning the structures contributing to hypopharyngeal or laryngeal obstruction in > 40% of patients.ConclusionsOur results indicate that DISE provides more information about the anatomical locations and pattern of obstruction, particularly regarding the specific structures contributing to hypopharyngeal and laryngeal obstruction. DISE changes surgical decision making compared to awake evaluation methods.Level of Evidence4. Laryngoscope, 124:1970–1974, 2014

ABSTRACTLewy body (LB) diseases are characterized by alpha‐synuclein (AS) aggregates in the central nervous system (CNS). Involvement of the peripheral autonomic nervous system (pANS) is increasingly recognized, although less studied. The aim of this study was to systematically analyze the distribution and severity of AS pathology in the CNS and pANS. Detailed postmortem histopathological study of brain and peripheral tissues from 28 brain bank donors (10 with Parkinson's disease [PD], 5 with dementia with LB [DLB], and 13 with non‐LB diseases including atypical parkinsonism and non‐LB dementia). AS aggregates were found in the pANS of all 15 LB disease cases (PD, DLB) in stellate and sympathetic ganglia (100%), vagus nerve (86.7%), gastrointestinal tract (86.7%), adrenal gland and/or surrounding fat (53.3%), heart (100%), and genitourinary tract (13.3%), as well as in 1 case of incidental Lewy body disease (iLBD). A craniocaudal gradient of AS burden in sympathetic chain and gastrointestinal tract was observed. DLB cases showed higher amounts of CNS AS aggregates than PD cases, but this was not the case in the pANS. No pANS AS aggregates were detected in Alzheimer's disease (AD) cases with or without CNS AS aggregates. All pathologically confirmed LB disease cases including 1 case of iLBD had AS aggregates in the pANS with a craniocaudal gradient of pathology burden in sympathetic chain and gastrointestinal tract. AS was not detected in the pANS of any AD case. These findings may help in the search of peripheral AS aggregates in vivo for the early diagnosis of PD. © 2014 International Parkinson and Movement Disorder Society

Fault‐tolerant distributed load/frequency supervisory strategies for networked multi‐area microgrids
Authors: Tedesco Francesco , Casavola Alessandro 
Published: January 2014

SUMMARYA distributed supervisory strategy for addressing load/frequency set‐point reconfiguration problems in networked multi‐area microgrid is presented. The aim is at finding a distributed coordination strategy able to reconfigure, whenever necessary in response to unexpected load changes and/or faults, the nominal set‐point on frequency and generated power to the generators of each area so that viable evolutions arise for the overall power system during transients and a new post‐fault sustainable equilibrium is reached. In order to demonstrate the effectiveness of the strategy, an example on a four‐area power system is presented. Copyright © 2014 John Wiley & Sons, Ltd.

Improving Portfolio Selection Using Option-Implied Volatility and Skewness
Authors: DeMiguel Victor , Plyakha Yuliya , Uppal Raman , Vilkov Grigory 
Published: January 2014

AbstractOur objective in this paper is to examine whether one can use option-implied information to improve the selection of mean-variance portfolios with a large number of stocks, and to document which aspects of option-implied information are most useful to improve their out-of-sample performance. Portfolio performance is measured in terms of volatility, Sharpe ratio, and turnover. Our empirical evidence shows that using option-implied volatility helps to reduce portfolio volatility. Using option-implied correlation does not improve any of the metrics. Using option-implied volatility, risk premium, and skewness to adjust expected returns leads to a substantial improvement in the Sharpe ratio, even after prohibiting short sales and accounting for transaction costs.
