Fidelity, Betrayals, and Contingent Utopian Solidarity in Thomas Pynchon's Vineland
Authors: Kolbuszewska Zofia 
Published: July 2018

ABSTRACT
This article addresses Thomas Pynchon's examination in Vineland of utopian desire that gives rise to the flawed and contingent solidarity of those victimized and hurt by American history. The Reaganite media appropriations of representations of the 1960s cultural and political revolution and mediated history of the political betrayals that contributed to the failure of political communities in the 1960s and 1970s are coupled in Pynchon's novel with an aesthetic reflection about the relationship between mimesis and fidelity. The utopian promise in Vineland is presented as inseparable from violent irruptions of past traumas into the present. In invoking a spectralized traumatic history of America, Pynchon inscribes the novel in the tradition of cryptomimetic writing. In conclusion it is demonstrated that, according to the writer, contingent and imperfect utopian solidarity with the living and the dead is the only, precarious, mainstay against fascist appropriations of the narrative of America.

ResumenLa Entrevista de Apego para Niños (EAN) es un nuevo instrumento de evaluación del apego basado en un procedimiento de completar historias. El objetivo principal de este estudio se basa en el análisis de la estructura y las propiedades psicométricas del EAN a través de análisis factoriales exploratorios sobre una muestra constituida por 115 niños y niñas españoles de entre 8 y 13 años (63 % niños). Otras dos muestras procedentes de una población en situación de riesgo psicosocial y de una población clínica fueron comparadas con la muestra principal con el fin de obtener evidencias de validez criterial. Los resultados obtenidos revelan una estructura interna compuesta de 4 factores que se refieren a reacciones del niño (positiva, confiada, negativa y desconfiada) y cinco factores referidos a interacciones niño-figura de apego (empática, confiada, positiva, negativa y desconfiada). Las escalas han demostrada una adecuada consistencia interna. La comparación de las escalas entre el grupo general y los grupos criteriales, y las correlaciones con los constructos relacionados indicaron una buena validez de constructo.AbstractThe Children Attachment Interview (EAN) is a new instrument based on story telling reports. The main purpose of this study is to analyze the structure and basic psychometric properties of the EAN through exploratory factor analyses based on a sample of 115 Spanish children aged 8 to 13 years (63 % boys). Another two matched samples from the risk social population and clinical population were compared with the main sample in order to obtain criterial validity. Findings reveal a multi-internal structure composed of four factors that refer to children´s reactions (positive, trustful, negative and mistrustful) and five factors that refer to child-attachment figure interactions (empathic, trustful, positive, rivalry and pro-arousal). Scales demonstrated adequate internal consistency. The comparison of scales between general and criterial groups, and correlations with related constructs indicate good construct validity.

Published: July 2018

AbstractA practical, simple, and efficient manganese‐catalysed oxidation of C(sp2)−H bond in readily available β‐carbonylenehydrazine under aerobic conditions has been developed. This protocol exhibits a wide range of functional group tolerance in β‐carbonylenehydrazines to afford α,β‐dicarbonylhydrazones. Experimental and theoretical results suggest that the reaction very likely proceeds through a radical pathway via a hydrogen‐atom‐transfer process promoted by a MnIII species.magnified image
Fluid‐Integrated Glass–Glass Laminate for Sustainable Hydronic Cooling and Indoor Air Conditioning

Published: July 2018

AbstractMore than 20% of the global energy demands are caused by heating, ventilating, and air conditioning in buildings. In particular during summer seasons and in warm climates, cooling loads are mostly neutralized by conventional air‐conditioning systems. Due to often very low primary temperature, these require high energy input, cause significant noise, uncomfortably cool draughts, and vertical air temperature gradients. Here, an energy efficient planar cooling device for large area integration with building interiors is presented. The system is based on a thin glass–glass capillary element and enables indoor temperature conditioning with a very low temperature gradient. The cooling ability of the device is demonstrated on a prototype scale of ≈0.5 m2. Computational predictions based on the obtained results show that by implementing the present system in a 24 m2 office room located in Central Europe with a window to floor ratio of 0.42, the specific cooling load could reach up to 80 W m−2 in summer. This corresponds to an effective indoor air temperature reduction by up to about 15 °C. In comparison to other hydronic systems, the present device provides significantly more freedom regarding design, layout, and functionality of modern buildings.
Nanoporous CaCO3 Coatings Enabled Uniform Zn Stripping/Plating for Long‐Life Zinc Rechargeable Aqueous Batteries

Published: July 2018

AbstractZn‐based batteries are safe, low cost, and environmentally friendly, as well as delivering the highest energy density of all aqueous battery systems. However, the application of Zn‐based batteries is being seriously hindered by the uneven electrostripping/electroplating of Zn on the anodes, which always leads to enlarged polarization (capacity fading) or even cell shorting (low cycling stability). How a porous nano‐CaCO3 coating can guide uniform and position‐selected Zn stripping/plating on the nano‐CaCO3‐layer/Zn foil interfaces is reported here. This Zn‐deposition‐guiding ability is mainly ascribed to the porous nature of the nano‐CaCO3‐layer, since similar functionality (even though relatively inferior) is also found in Zn foils coated with porous acetylene black or nano‐SiO2 layers. Furthermore, the potential application of this strategy is demonstrated in Zn|ZnSO4+MnSO4|CNT/MnO2 rechargeable aqueous batteries. Compared with the ones with bare Zn anodes, the battery with a nano‐CaCO3‐coated Zn anode delivers a 42.7% higher discharge capacity (177 vs 124 mAh g−1 at 1 A g−1) after 1000 cycles.
Gallium Hydrides and O/N‐Donors as Tunable Systems in C−F Bond Activation
Authors: Jaeger Alma D. , Walter Ruben , Ehm Christian , Lentz Dieter 
Published: July 2018

AbstractThe gallium hydrides (iBu)2GaH (1 a), LiGaH4 (1 b) and Me3N⋅GaH3 (1 c) hydrodefluorinate vinylic and aromatic C−F bonds when O and N donor molecules are present. 1 b exhibits the highest reactivity. Quantitative conversion to the hydrodefluorination (HDF) products could be observed for hexafluoropropene and 1,1,3,3,3‐pentafluoropropene, 94 % conversion of pentafluoropyridine and 49 % of octafluorotoluene. Whereas for the HDF with 1 b high conversions are observed when catalytic amounts of O donor molecules are added, for 1 a, the addition of N donor molecules lead to higher conversions. The E/Z selectivity of the HDF of 1,1,3,3,3‐pentafluoropropene is donor‐dependent. DFT studies show that HDF proceeds in this case via the gallium hydride dimer–donor species and a hydrometallation/elimination sequence. Selectivities are sensitive to the choice of donor, as the right donor can lead to an on/off switching during catalysis, that is, the hydrometallation step is accelerated by the presence of a donor, but the donor dissociates prior to elimination, allowing the inherently more selective donorless gallium systems to determine the selectivity.
Predicting physically violent misconduct in prison: A comparison of four risk assessment instruments

Published: July 2018

AbstractViolence in correctional facilities is an important issue for both prisoners and prison staff. Risk assessment instruments have demonstrated their accuracy in predicting the risk of (re) offending and institutional violence in psychiatric settings, but less is known about their ability to predict violent misconduct in prison. The present study applied four risk assessment instruments (Structured Assessment of Protective Factors for violence risk, Historical Clinical Risk Management‐20, Psychopathy checklist – Revised, and Violent Risk Appraisal Guide) to 52 violent offenders in a Swiss prison in order to evaluate the instruments' predictive validities. Outcomes were instances of physically violent, other and any misconduct as recorded in prison files during the 12 months following the prisoners' assessments. Approximately 15% of offenders committed physically violent misconduct and approximately 42% committed any misconduct. The results show that mainly dynamic assessment tools are as good predictors of physically violent misconduct as mainly static assessment tools. Targeting dynamic factors could increase the effectiveness of interventions to reduce the risk of physical violence in prison.

Published: July 2018

AbstractObjectiveOur study was designed to explore the association miR‐335‐5p and BCL2L2 and to investigate the influence of miR‐335‐5p/BCL2L2 axis on cisplatin‐resistant ovarian cancer cells.MethodsMicroarray analysis was used to determine differentially expressed microRNAs in primary and cisplatin‐resistant A2780 cells. Cell function experiments were conducted to investigate the effect of miR‐335‐5p on the cisplatin sensitivity of A2780 cells. The targeted relationship between BCL2L2 mRNA and miR‐335‐5p was validated through luciferase assay. Tumor xenograft was performed to confirm the function of miR‐335‐5p in restoring the cisplatin sensitivity of the ovarian cancer cells.ResultsMiR‐335‐5p was lowly expressed in cisplatin‐resistant A2780 cells. Overexpression of miR‐335‐5p reduced cell survival and enhanced cisplatin‐induced cell apoptosis. BCL2L2 mRNA was a target of miR‐335‐5p, and silencing of BCL2L2 showed the similar results on the cell viability as miR‐335‐5p overexpression.ConclusionUpregulation of miR‐335‐5p expression enhanced the cisplatin sensitivity of ovarian cancer cells through suppressing BCL2L2, suggesting the potential of miR‐335‐5p/BCL2L2 axis as a therapeutic target for the cisplatin resistance of patients with ovarian cancer.
Hydrogen Bonding and Proton Transfer in Aqueous Toluene Microdroplets Studied by Particle Collision Electrochemistry
Authors: Paul Dilip K. , Meng Kejie , Omanovic Dario , Alvarez Julio C. 
Published: July 2018

AbstractThis report describes hydrogen bonding and protonation in toluene microdroplets (0.4 to 4.0 μm) dispersed in water. Such effects are revealed by studying the two‐electron reduction of tetrachloro‐1,4‐benzoquinone (TCBQ) trapped inside the toluene droplets using particle collision electrochemistry (PCE). This approach allows interrogation of microscopic particles in Brownian motion colliding with an ultramicroelectrode and can provide information when the collision encounter is coupled to an electrochemical event. Upon addition of acids in homogeneous toluene, the half‐wave potential of TCBQ shifts positively (easier reduction), thus implying hydrogen bonding and/or protonation of the reduction product TCBQ2−. The shift is commensurate to the proton donating capacity of each acid, so that, acetic acid (pKa=4.8) displays higher shift than oleic acid (pKa=9.9). However, when the reduction takes place inside toluene droplets, the trend is completely reversed and appears to be driven by preferential partition of acetic acid in water, as opposed to the hydrophobic oleic acid. Furthermore, these effects compete with the underlying binding between TCBQ2− and the tetraalkyl phosphonium cation of the ionic liquid used to enhance the conductivity of toluene. This work aims to illustrate a subtle, yet consequential effect that emerges from micro‐confinement of immiscible phases, as well as the potential of PCE to extract chemical reactivity information at the organic‐water interface.

Published: July 2018

AbstractThe reaction of hydrogen‐terminated Si(100) with 1,8‐nonadiyne was previously shown to afford robust surfaces where oxidation of the substrate is not evident. Here, the experimental conditions required for reacting hydrogen‐terminated Si(100) with α,ω‐diynes of different lengths is explored via thermal hydrosilylation of 1,6‐heptadiyne, 1,8‐nonadiyne, 1,10‐undecadiyne and 1,15‐hexadecadiyne. X‐ray photoelectron spectroscopy indicated monolayers were successfully formed with oxide levels below the XPS detection limit for molecules with lengths varying from 7 to 11 carbons. It was observed that the apparent rate of electron transfer (ket) was affected not only by the SAM thickness, but also by hopping between ferrocene moieties where the presence of tiny oxidative defects act as electron transfer hotspots.

AbstractA simple imine clip‐and‐cleave concept has been developed for the selective hydroxylation of non‐activated CH bonds in aliphatic aldehydes with dioxygen through a copper complex. The synthetic protocol involves reaction of a substrate aldehyde with N,N‐diethyl‐ethylendiamine to give the corresponding imine, which is used as a bidentate donor ligand forming a copper(I) complex with [Cu(CH3CN)4][CF3SO3]. After exposure of the reaction mixture to dioxygen acidic cleavage and aqueous workup liberates the corresponding β‐hydroxylated aldehyde. The concept for the hydroxylation of trimethylacetaldehyde as well as adamantane and diamantane 1‐carbaldehydes was investigated and the corresponding β‐hydroxy aldehydes were obtained with high selectivities. The results of low temperature stopped‐flow measurements indicate the formation of a bis(μ‐oxido)dicopper complex as reactive intermediate. According to density functional theory (DFT, RI‐BLYP‐D3/def2‐TZVP(SDD)/ COSMO(CH2Cl2)//RI‐PBE‐D3/def2‐TZVP(SDD)) computations CH bonds suitably predisposed to the [Cu2O2]2+ core undergo hydroxylation in a concerted step with particularly low activation barriers, which explains the experimentally observed regioselectivities.
Characterization of septin expression in normal and fibrotic kidneys

Published: July 2018

AbstractChronic kidney disease (CKD) is characterized by the loss of nephrons and worsening organ‐fibrosis that leads to deterioration and ultimately the total breakdown of kidney function. Renal fibrosis has become a major public health problem worldwide and necessitates hemodialysis and kidney transplantation in affected patients. CKD is mainly characterized by the activation and proliferation of interstitial fibroblasts and by excessive synthesis and accumulation of extracellular matrix components, causing the disruption of the normal tissue architecture of the kidney. Septins are GTPase proteins associated with membranes, actin filaments, and microtubules and are undoubtedly crucial for cytoskeleton organization. Although some septins are involved in liver fibrosis, they have not been investigated in the context of renal fibrosis. Here, we show that numerous septins are expressed in the healthy kidney and demonstrate in fibrotic mouse kidneys that various septins are remarkably up‐regulated in the tubulointerstitium compared to contralateral control kidneys. We observed the same findings in human fibrotic kidneys. In both healthy and fibrotic kidneys, septins are coexpressed with extracellular matrix components, reinforcing the structural function of septins as cytoskeletal components. Furthermore, we could show in septin 8‐deficient mice that septin 8 is dispensable for the formation of renal fibrosis, and that no other septin was compensatory changed in kidneys compared to wild‐type mice.

Published: July 2018

AbstractHereditary neuralgic amyotrophy (HNA) is an autosomal dominant disorder associated with episodic, recurrent, and painful neuropathies affecting the nerves of the brachial plexus. In this study, we report on a family of Lebanese descent with HNA onset in early childhood. The affected family members presented with platelet dysfunction. Platelet aggregation was reduced after stimulation with the agonists ADP and epinephrine in all affected family members. Flow cytometric analyses revealed impaired platelet δ‐secretion. The index patient and one brother suffered from kidney cysts. Molecular genetic analysis revealed a heterozygous duplication of exon 2 within the septin 9 (SEPT9) gene in all the affected family members. Such a young child with HNA (aged 2 years) caused by SEPT9 duplication has not been described so far.
Flow Cytometry Analysis of Fungal Ploidy
Authors: Todd Robert T. , Braverman Ann L. , Selmecki Anna 
Published: July 2018

AbstractPloidy, the number of sets of homologous chromosomes in a cell, can alter cellular physiology, gene regulation, and the spectrum of acquired mutations. Advances in single‐cell flow cytometry have greatly improved the understanding of how genome size contributes to diverse biological processes including speciation, adaptation, pathogenesis, and tumorigenesis. For example, fungal pathogens can undergo whole genome duplications during infection of the human host and during acquisition of antifungal drug resistance. Quantification of ploidy is dramatically affected by the nucleic acid staining technique and the flow cytometry analysis of single cells. Ploidy in fungi is also impacted by samples that are heterogeneous for both ploidy and morphology, and control strains with known ploidy must be included in every flow cytometry experiment. To detect ploidy changes within fungal strains, the following protocol was developed to accurately and dependably interrogate single‐cell ploidy. © 2018 by John Wiley & Sons, Inc.

Published: July 2018

AbstractPoor diet reporting and improperly controlling laboratory animal diet continues to reduce our ability to interpret data effectively in animal studies. In order to make the best use of our resources and improve research transparency, proper reporting methods that include a diet design are essential to improving our understanding of the links between gut health and metabolic disease onset. This unit will focus on the importance of diet choice in laboratory animal studies, specifically as it relates to gut health, microbiome, and metabolic disease development. The two most commonly used diet types, grain‐based (GB) diets, and purified ingredient diets, will each be described, with particular emphasis on their differences in dietary fiber. A further description of how these diet types and fiber can affect gut morphology and microbiota will be provided as well as how purified ingredient diets may be improved upon. © 2018 by John Wiley & Sons, Inc.
