Authors: Kong Zhiyun , Wei Junfu , Yang Liang , Luo Zian , Zhao Kongyin , Wang Xiaolei 
Published: July 2014

ABSTRACTIn this article, poly(vinylidene fluoride) (PVDF) hollow fiber membrane and acrylic acid (AA) were co‐irradiated by high‐energy electron beam to introduce hydrophilic carboxylic groups on the membrane surface. Thermal capability, mechanical performance, pore size, and permeation property were investigated to determine the stability of the membrane pore structure before and after irradiation polymerization. The decomposition temperature, melting point, glass transition temperature, and breaking force of the PVDF‐g‐AA membrane increased slightly because of irradiation grafting polymerization. After 15 months of storage, the pore size distribution of the PVDF‐g‐AA membrane became smaller and more dispersive. The pure water flux and the rejection to bovine serum albumin of the PVDF‐g‐AA membrane increased significantly with the increase in hydrophilicity and decrease in pore size. The results indicated that the structure and properties of the PVDF hollow fiber membrane were stable after high‐energy electron beam irradiation grafting polymerization, even after 15 months of storage. © 2014 Wiley Periodicals, Inc.

Published: July 2014

ABSTRACTThe aims of this study were to determine the various dimensions of the normal facial canal and to identify the spatial relationships between the facial canal and its adjacent structures using microcomputed tomography (micro‐CT) imaging and three‐dimensional (3D) reconstruction. The petrous parts of 54 temporal bones were scanned using micro‐CT with a slice thickness of 35 μm. The serial micro‐CT images were used to reconstruct 3D volumes of the facial canal and the bony labyrinth with the aid of computer software. These volumes were used to measure 31 dimensions of the facial canal and its spatial relationships with adjacent structures. The length of the meatal segment, the tympanic segment, and the mastoid segment were significantly larger in males than in females (p < 0.05). The narrowest portions of the facial canal were immediately lateral to the meatal foramen in the labyrinthine segment and the midpoint of the tympanic segment. The distance between the origin of the canal for the chorda tympani nerve and midpoint of the stylomastoid foramen was 35.3% of the length of the mastoid segment, and the angle between the tympanic segment and the lateral semicircular canal was 16.3°. The angle between the mastoid segment and the canal for the chorda tympani nerve could be classified into two groups: <180° and >180°. These findings represent supplemental data for improving the detailed understanding of the facial canal anatomy. Anat Rec, 297:1808–1816, 2014. © 2014 Wiley Periodicals, Inc.

Published: July 2014

AbstractTwo novel propeller‐shaped, trigeminal‐ligand‐containing, flexible trinuclear PtII complexes, {[Pt(dien)]3(ptp)}(NO3)6 (1) and {[Pt(dpa)]3(ptp)}(NO3)6 (2) (dien: diethylenetriamine; dpa: bis‐(2‐pyridylmethyl)amine; ptp: 6′‐(pyridin‐3‐yl)‐3,2′:4′,3′′‐terpyridine), have been designed and synthesized, and their interactions with G‐quadruplex (G4) sequences are characterized. A combination of biophysical and biochemical assays reveals that both PtII complexes exhibit higher affinity for human telomeric (hTel) and c‐myc promoter G4 sequences than duplex DNA. Complex 1 binds and stabilizes hTel G4 sequence more effectively than complex 2. Both complexes are found to induce and stabilize either antiparallel or parallel conformation of G4 structures. Molecular docking studies indicate that complex 1 binds into the large groove of the antiparallel hTel G4 structure (PDB ID: 143D) and complex 2 stacks onto the exposed G‐quartet of the parallel hTel G4 structure (PDB ID: 1KF1). Telomeric repeat amplification protocol assays demonstrate that both complexes are good telomerase inhibitors, with IC50 values of (16.0±0.4) μM and (4.20±0.25) μM for 1 and 2, respectively. Collectively, the results suggest that these propeller‐shaped flexible trinuclear PtII complexes are effective and selective G4 binders and good telomerase inhibitors. This work provides valuable information for the interaction between multinuclear metal complexes with G4 DNA.
Direct Silica Encapsulation of Self‐Assembled‐Monolayer‐Based Surface‐Enhanced Raman Scattering Labels with Complete Surface Coverage of Raman Reporters by Noncovalently Bound Silane Precursors
Authors: Schütz Max , Salehi Mohammad , Schlücker Sebastian 
Published: July 2014

AbstractSilica‐coated surface‐enhanced Raman scattering (SERS) labels with a self‐assembled monolayer (SAM) on the entire surface of the metal colloid combine high chemical and mechanical stability with bright and reproducible Raman signals due to the complete surface coverage and uniform molecular orientation within the SAM. Currently available chemical syntheses are either based on the direct encapsulation of covalently bound silane precursors or comprise several steps, such as the sequential addition of noncovalently bound polyelectrolytes to render the surface vitreophilic. Here, a generic approach for the direct and fast silica encapsulation of commercially available Raman reporter molecules with polar head groups by noncovalently bound silane precursors is reported. The formation of highly SERS‐active silica‐coated clusters during silica encapsulation is determined by several parameters, in particular the type of Raman reporter molecule, the solvent, and the type and amount of the silane precursor.
Classification modeling approach for vehicle dynamics model‐integrated traffic simulation assessing surrogate safety
Authors: So Jaehyun (Jason) , Park Byungkyu (Brian) , Yun Ilsoo 
Published: July 2014

SummaryTo assess safety impacts of untried traffic control strategies, an earlier study developed a vehicle dynamics model‐integrated (i.e., VISSIM‐CarSim‐SSAM) simulation approach and evaluated its performance using surrogate safety measures. Although the study found that the integrated simulation approach was a superior alternative to existing approaches in assessing surrogate safety, the computation time required for the implementation of the integrated simulation approach prevents it from using it in practice. Thus, this study developed and evaluated two types of models that could replace the integrated simulation approach with much faster computation time, feasible for real‐time implementation. The two models are as follows: (i) a statistical model (i.e., logit model) and (ii) a nonparametric approach (i.e., artificial neural network). The logit model and the neural network model were developed and trained on the basis of three simulation data sets obtained from the VISSIM‐CarSim‐SSAM integrated simulation approach, and their performances were compared in terms of the prediction accuracy. These two models were evaluated using six new simulation data sets. The results indicated that the neural network approach showing 97.7% prediction accuracy was superior to the logit model with 85.9% prediction accuracy. In addition, the correlation analysis results between the traffic conflicts obtained from the neural network approach and the actual traffic crash data collected in the field indicated a statistically significant relationship (i.e., 0.68 correlation coefficient) between them. This correlation strength is higher than that of the VISSIM only (i.e., the state of practice) simulation approach. The study results indicated that the neural network approach is not only a time‐efficient way to implementing the VISSIM‐CarSim‐SSAM integrated simulation but also a superior alternative in assessing surrogate safety.

A label‐free DNAzyme‐cleaving fluorescence method for the determination of trace Pb2+ based on catalysis of AuPd nanoalloy on the reduction of rhodamine 6G
Authors: Tang Meiling , Wen Guiqing , Luo Yanghe , Kang Caiyan , Liang Aihui , Jiang Zhiliang 
Published: July 2014

AbstractThe substrate chain of double‐stranded DNA (dsDNA) could be specifically cleaved by Pb2+ to release single‐stranded DNA (ssDNA) that adsorbs onto the AuPd nanoalloy (AuPdNP) to form a stable AuPdNP–ssDNA complex, but the dsDNA can not protect AuPdNPs in large AuPdNP aggregates (AuPdNPA) under the action of NaCl. AuPdNP–ssDNA and large AuPdNPA could be separated by centrifugation. On increasing the concentration of Pb2+, the amount of released ssDNA increased; AuPdNP–ssDNA increased in the centrifugation solution exhibiting a catalytic effect on the slow reaction of rhodamine 6G (Rh6G) and NaH2PO2, which led to fluorescence quenching at 552 nm. The decrease in fluorescence intensity (ΔF) was linear to the concentration of Pb2+ within the range 0.33–8.00 nmol/L, with a detection limit of 0.21 nmol/L. The proposed method was applied to detect Pb2+ in water samples, with satisfactory results. Copyright © 2014 John Wiley & Sons, Ltd.

AbstractBackgroundMelodic Intonation Therapy (MIT) uses the melodic elements of speech to improve language production in severe nonfluent aphasia. A crucial element of MIT is the melodically intoned auditory input: the patient listens to the therapist singing a target utterance. Such input of melodically intoned language facilitates production, whereas auditory input of spoken language does not.MethodsUsing a sparse sampling fMRI sequence, we examined the differential auditory processing of spoken and melodically intoned language. Nineteen right‐handed healthy volunteers performed an auditory lexical decision task in an event related design consisting of spoken and melodically intoned meaningful and meaningless items. The control conditions consisted of neutral utterances, either melodically intoned or spoken.ResultsIrrespective of whether the items were normally spoken or melodically intoned, meaningful items showed greater activation in the supramarginal gyrus and inferior parietal lobule, predominantly in the left hemisphere. Melodically intoned language activated both temporal lobes rather symmetrically, as well as the right frontal lobe cortices, indicating that these regions are engaged in the acoustic complexity of melodically intoned stimuli. Compared to spoken language, melodically intoned language activated sensory motor regions and articulatory language networks in the left hemisphere, but only when meaningful language was used.DiscussionOur results suggest that the facilitatory effect of MIT may – in part – depend on an auditory input which combines melody and meaning.ConclusionCombined melody and meaning provide a sound basis for the further investigation of melodic language processing in aphasic patients, and eventually the neurophysiological processes underlying MIT.

AbstractHistone deacetylase inhibitors (HDACIs) are being tested in clinical trials for the treatment of solid tumors. While most studies have focused on the reexpression of silenced tumor suppressor genes, a number of genes/pathways are downregulated by HDACIs. This provides opportunities for combination therapy: agents that further disable these pathways through inhibition of residual gene function are speculated to enhance cell death in combination with HDACIs. A previous study from our group indicated that mitotic checkpoint kinases such as PLK1 and Aurora A are downregulated by HDACIs. We used in vitro and in vivo xenograft models of prostate cancer (PCA) to test whether combination of HDACIs with the pan‐aurora kinase inhibitor AMG 900 can synergistically or additively kill PCA cells. AMG 900 and HDACIs synergistically decreased cell proliferation activity and clonogenic survival in DU‐145, LNCaP, and PC3 PCA cell lines compared to single‐agent treatment. Cellular senescence, polyploidy, and apoptosis was significantly increased in all cell lines after combination treatment. In vivo xenograft studies indicated decreased tumor growth and decreased aurora B kinase activity in mice treated with low‐dose AMG 900 and vorinostat compared to either agent alone. Pharmacodynamics was assessed by scoring for phosphorylated histone H3 through immunofluorescence. Our results indicate that combination treatment with low doses of AMG 900 and HDACIs could be a promising therapy for future clinical trials against PCA.

Published: July 2014

AbstractDuring industrial manufacturing, formulation, and storage, the tendency towards isomerization of astaxanthin (AXT) may affect its bioavailability. Potential additives like potassium carbonate, potassium acetate, dipotassium hydrogen orthophosphate, potassium hydroxide, and cesium carbonate were mixed to solutions of AXT and chloroform in order to increase the stability of all‐trans AXT while present in solution. The additives should not cause any damage to neither the dissolved nor the crystalline substance. Concentration changes in the course of time were measured and monitored by HPLC and a photometer. The additives exerted different effects on the dissolved AXT, either enhancing or weakening the isomerization processes and/or decomposition. Potassium carbonate and dipotassium hydrogen orthophosphate insufficiently affected the preservation of the all‐trans AXT structure. In contrast, potassium acetate, potassium hydroxide, and cesium carbonate led to satisfying results and can be recommended as additives.

Published: July 2014

AbstractA simple access to silylated and germylated binuclear heterocycles, based on an original anionic rearrangement, is described. A set of electron‐rich and electron‐poor silylated aromatic and heteroaromatic substrates were tested to understand the mechanism and the factors controlling this rearrangement, in particular its regioselectivity. This parameter was shown to follow the rules proposed before from a few examples. Then, the effect of the substituents borne by the silicon itself, in particular the selectivity of the ligand transfer, was studied. Additionally, this chemistry was extended to germylated substrates. A hypervalent germanium species, comparable to the putative intermediate proposed with silicon, seems to be involved. However, a pathway implicating the elimination of LiCH2Cl was observed for the first time with this element, leading to unexpected products of the benzo‐oxa (or benzo‐aza) germol‐type.
