“That was the Last Time I Saw my House”: The Importance of Place Attachment among Children and Youth in Disaster Contexts
Authors: Scannell Leila , Cox Robin S. , Fletcher Sarah , Heykoop Cheryl 
Published: July 2016

AbstractPlace attachment is important for children and youth's disaster preparedness, experiences, recovery, and resilience, but most of the literature on place and disasters has focused on adults. Drawing on the community disaster risk reduction, recovery, and resilience literature as well as the literature on normative place attachment, children and youth's place‐relevant disaster experiences are examined. Prior to a disaster, place attachments are postulated to enhance children and youth's disaster preparedness contributions and reinforce their pre‐disaster resilience. During a disaster, damage of, and displacement from, places of importance can create significant emotional distress among children and youth. Following a disaster, pre‐existing as well as new place ties can aid in their recovery and bolster their resilience moving forward. This framework enriches current theories of disaster recovery, resilience, and place attachment, and sets an agenda for future research.

Published: July 2016

ObjectiveThe Ts65Dn (Ts) mouse model of Down syndrome (DS) is exquisitely sensitive to an infantile spasms phenotype induced by γ‐aminobutyric acidB receptor (GABABR) agonists. The Ts mouse contains the core genomic triplication of the DS critical region, which includes 3 copies of the Kcnj6 gene that encodes the GABABR‐coupled G protein‐coupled inward rectifying potassium channel subunit 2 (GIRK2) channel. We test the hypothesis that GIRK2 is necessary for the GABABR agonist‐induced infantile spasms phenotype in Ts.MethodsWe assessed the result of either genetic or pharmacological knockdown of the GIRK2 channel in Ts brain upon the GABABR agonist‐induced infantile spasms phenotype in the Ts mouse model of DS. As well, we examined GABABR currents in hippocampal neurons prepared from GIRK2‐trisomic Ts control mice and GIRK2‐disomic Ts mice in which Kcnj6 had been genetically knocked down from 3 to 2 copies.ResultsThe reduction of the copy number of Kcnj6 in Ts mice rescued the GABABR agonist‐induced infantile spasms phenotype. There was an increase in GABABR‐mediated GIRK2 currents in GIRK2‐trisomic Ts mouse hippocampal neurons, which were normalized in the GIRK2‐disomic Ts mice. Similarly, pharmacological knockdown of the GIRK2 channel in Ts brain using the GIRK antagonist tertiapin‐Q also rescued the GABABR agonist‐induced infantile spasms phenotype in Ts mutants.InterpretationThe GABABR‐coupled GIRK2 channel is necessary for the GABABR agonist‐induced infantile spasms phenotype in the Ts mouse and may represent a novel therapeutic target for the treatment of infantile spasms in DS.

Published: July 2016

AbstractSupported Au nanocatalysts have attracted intensive interest because of their unique catalytic properties. Their poor thermal stability, however, presents a major barrier to the practical applications. Here we report an ultrastable Au nanocatalyst by localizing the Au nanoparticles (NPs) in the interfacial regions between the TiO2 and hydroxyapatite. This unique configuration makes the Au NP surface partially encapsulated due to the strong metal–support interaction and partially exposed and accessible by the reaction molecules. The strong interaction helps stabilizing the Au NPs while the partially exposed Au NP surface provides the active sites for reactions. Such a catalyst not only demonstrated excellent sintering resistance with high activity after calcination at 800 °C but also showed excellent durability that outperforms a commercial three‐way catalyst in a simulated practical testing, suggesting great potential for practical applications.
Formation of Coaxial Nanocables with Amplified Supramolecular Chirality through an Interaction between Carbon Nanotubes and a Chiral π‐Gelator
Authors: Vedhanarayanan Balaraman , Nair Vishnu S. , Nair Vijayakumar C. , Ajayaghosh Ayyappanpillai 
Published: July 2016

AbstractIn an attempt to gather experimental evidence for the influence of carbon allotropes on supramolecular chirality, we found that carbon nanotubes (CNTs) facilitate amplification of the molecular chirality of a π‐gelator (MC‐OPV) to supramolecular helicity at a concentration much lower than that required for intermolecular interaction. For example, at a concentration 1.8×10−4 m, MC‐OPV did not exhibit a CD signal; however, the addition of 0–0.6 mg of SWNTs resulted in amplified chirality as evident from the CD spectrum. Surprisingly, AFM analysis revealed the formation of thick helical fibers with a width of more than 100 nm. High‐resolution TEM analysis and solid‐state UV/Vis/NIR spectroscopy revealed that the thick helical fibers were cylindrical cables composed of individually wrapped and coaxially aligned SWNTs. Such an impressive effect of CNTs on supramolecular chirality and cylindrical‐cable formation has not been reported previously.
A Molybdenum(0) Isocyanide Analogue of Ru(2,2′‐Bipyridine)32+: A Strong Reductant for Photoredox Catalysis
Authors: Büldt Laura A. , Guo Xingwei , Prescimone Alessandro , Wenger Oliver S. 
Published: July 2016

AbstractWe report the first homoleptic Mo0 complex with bidentate isocyanide ligands, which exhibits metal‐to‐ligand charge transfer (3MLCT) luminescence with quantum yields and lifetimes similar to Ru(bpy)32+ (bpy=2,2′‐bipyridine). This Mo0 complex is a very strong photoreductant, which manifests in its capability to reduce acetophenone with essentially diffusion‐limited kinetics as shown by time‐resolved laser spectroscopy. The application potential of this complex for photoredox catalysis was demonstrated by the rearrangement of an acyl cyclopropane to a 2,3‐dihydrofuran, which is a reaction that requires a reduction potential so negative that even the well‐known and strongly reducing Ir(2‐phenylpyridine)3 photosensitizer cannot catalyze it. Our study thus provides the proof‐of‐concept for the use of chelating isocyanides to obtain Mo0 complexes with long‐lived 3MLCT excited states that are applicable to unusually challenging photoredox chemistry.
DMSO enhanced conformational switch of an interfacial enzyme

Published: July 2016

AbstractInterfacial proteins function in unique heterogeneous solvent environments, such as water–oil interfaces. One important example is microbial lipase, which is activated in an oil‐water emulsion phase and has many important enzymatic functions. A unique aprotic dipolar organic solvent, dimethyl sulfoxide (DMSO), has been shown to increase the activity of lipases, but the mechanism behind this enhancement is still unknown. Here, all‐atom molecular dynamics simulations of lipase in a binary solution were performed to examine the effects of DMSO on the dynamics of the gating mechanism. The amphiphilic α5 region of the lipase was a focal point for the analysis, since the structural ordering of α5 has been shown to be important for gating under other perturbations. Compared to the closed‐gorge ensemble in an aqueous environment, the conformational ensemble shifts towards open‐gorge structures in the presence of DMSO solvents. Increased width of the access channel is particularly prevalent in 45% and 60% DMSO concentrations (w/w). As the amount of DMSO increases, the α5 region of the lipase becomes more α‐helical, as we previously observed in studies that address water–oil interfacial and high pressure activation. We believe that the structural ordering of α5 plays an essential role on gating and lipase activity.
Monitoring of the degradation kinetics of diatrizoate sodium to its cytotoxic degradant using a stability‐indicating high‐performance liquid chromatographic method

Published: July 2016

AbstractThe X‐ray diagnostic agent sodium diatrizoate (DTA) was studied for chemical degradation. The 3,5‐diamino derivative was found to be the alkaline and acidic degradation product. The 3,5‐diamino degradate is also the synthetic precursor of DTA and it is proved to have cytotoxic and mutagenic effects. A sensitive, selective and precise high‐performance liquid chromatographic stability‐indicating method for the determination of DTA in the presence of its acidic degradation product and in pharmaceutical formulation was developed and validated. Owing to the high toxicity of the degradation product, the kinetics of the acidic degradation process was monitored by the developed RP‐HPLC method. The reaction was found to follow pseudo‐first order kinetics. The kinetic parameters such as rate constant (K) and half‐life (t½) were calculated under different temperatures and acid concentrations; activation energy was estimated from the Arrhenius plot. The developed RP‐HPLC method depends on isocratic elution of a mobile phase composed of methanol–water (25:75 v/v; pH adjusted with phosphoric acid), and UV detection at 238 nm. The method showed good linearity over a concentration range of 2–100 μg/mL with mean percentage recovery of 100.04 ± 1.07. The selectivity of the proposed method was tested using laboratory‐prepared mixtures. The proposed method has been successfully applied to the analysis of DTA in pharmaceutical dosage forms without interference from other dosage form additives and the results were statistically compared with the official USP method. Validation of the proposed method was performed according to International Conference on Harmonization guidelines.
An HPLC method for the determination of selected amino acids in human embryo culture medium
Authors: Drábková Petra , Andrlová Lenka , Kanďár Roman 
Published: July 2016

AbstractA method for the determination of selected amino acids in culture medium using HPLC with fluorescence detection is described. Twenty hours after intra‐cytoplasmic sperm injection, one randomly selected zygote was transferred to the culture medium. After incubation (72 h after fertilization), the culture medium in which the embryo was incubated and blank medium was immediately stored at −80°C. Filtered medium samples were derivatized with ortho‐phthalaldehyde (naphthalene‐2,3‐dicarboxaldehyde), forming highly fluorescent amino acids derivatives. Reverse‐phase columns (LichroCART, Purospher STAR RP18e or Ascentis Express C18) were used for the separation. The derivatives were analyzed by gradient elution with a mobile phase containing ethanol and sodium dihydrogen phosphate. The analytical performance of this method is satisfactory for all amino acids; the intra‐assay coefficients of variation were <10% and quantitative recoveries were between 95.5 and 104.4%. Changes in the levels of selected amino acids before and after human embryo cultivation were observed. After embryo incubation, the levels of all amino acids in the medium were increased, apart from aspartate and asparagine. After the cultivation of some embryos, amino acids which were not part of the medium were detected. Low amino acids turnover was observed in some embryos.

Authors: Regassa Alemu , Park Kye Won , Kim Woo Kyun 
Published: July 2016

AbstractA study was conducted to examine the effect of phenamil on adipogenic differentiation and expression of key adipogenic transcripts in hen preadipocytes. Preadipocytes were isolated from 20‐week old Single Comb White Leghorn hens (Gallas gallus, Lohman strain). The experiment lasted for 48 h and had six treatments. Non‐treated control (C) cells, cells treated with dexamethasone, 3‐isobutyl‐1‐methylxanthine, insulin, and oleic acid (DMIOA) (T1), DMIOA + 15 μM phenamil (T2), DMIOA + 30 μM phenamil (T3), 15 μM phenamil alone (T4), and 30 μM phenamil alone (T5). Neutral lipid accumulation and the mRNA expression of key adipogenic transcripts were measured in all treatments and compared. Lipid accumulation was detected in T1, T2, and T3 only. Expression of peroxisome proliferator receptor‐activator gamma 2 (PPARγ2), the core enhancer binding protein α (C/EBPα), C/EBPβ, fatty acid binding protein 4 (FABP4), and lipoprotein lipase (LPL) as well as ETS variant 4 (ETV4) and 5 was higher (P < 0.05) in T2, T3, T4, and T5 compared to C. Expression of these transcripts was higher (P < 0.05) in T2 and T3 compared to T4 and T5. The core enhancer binding protein α, C/EBPβ, and FABP4 were highly expressed (P < 0.05) in T1 compared to C. However, the expression of PPARγ2, LPL, and ETV4 and ETV5 was not significantly different. Expression of C/EBPα, C/EBPβ, and FABP4 was higher (P < 0.05) in T2 and T3 compared to T1. Expression of sterol regulatory element binding protein 1 (SREBP1) and leptin receptor (LEPR) was not significantly different among the treatments. In conclusion, phenamil enhances DMIOA‐induced adipogenic differentiation of hen preadipocytes but does not induce adipogenesis by itself.
Highly Efficient Vapor‐Phase Hydrogenation of Biomass‐Derived Levulinic Acid Over Structured Nanowall‐Like Nickel‐Based Catalyst
Authors: Li Wei , Fan Guoli , Yang Lan , Li Feng 
Published: July 2016

AbstractWith ever increasing demand of sustainable energy, biomass has been regarded as an ideal alternative to fossil resources. Herein, hierarchical three‐dimensional nickel‐based nanowalls on a nickel foam substrate were fabricated by a Ni–Zr–Al layered double hydroxide (NiZrAl–LDH) precursor route, which involved in situ growth of the Zr‐containing precursor on the Ni foam strut through surface activation without an external nickel source. After calcination–reduction treatment, the nanowalls were applied as a structured catalyst for selectively hydrogenating biomass‐derived levulinic acid to γ‐valerolactone. Systematic characterization revealed that highly dispersed Ni nanoparticles could be generated on the platelet‐like Zr‐containing oxide matrix derived from hierarchical 3 D NiZrAl–LDH nanowalls. Under vapor‐phase, solvent‐free hydrogenation conditions (250 °C, ambient pressure), the yield and productivity for as‐fabricated Ni‐based structured catalyst could reach as high as 97.7 % and 5.747 kgGVL kgcat−1 h−1, respectively. Such high catalytic efficiency was reasonably attributable to highly dispersed Ni nanoparticles and abundant surface Lewis acid sites, as well as favorable heat‐transfer nature of present catalytic system. Moreover, the newly developed structured nanowall‐like Ni‐based catalyst possesses high structural and chemical stability, which makes the vapor‐phase hydrogenation process promising in terms of green sustainable chemistry.
