Published: February 2017

AbstractHighly active, cost‐effective, and durable catalysts for oxygen evolution reaction (OER) are required in energy conversion and storage processes. A facile synthesis of CoFe layered double hydroxide (CoFe LDH) is reported as a highly active and stable oxygen evolution catalyst. By varying the concentration of the metal ion precursor, the Co/Fe ratios of LDH products can be tuned from 0.5 to 7.4. The structure and electrocatalytic activity of the obtained catalysts were found to show a strong dependence on the Co/Fe ratios. The Co2Fe1 LDH sample exhibited the best electrocatalytic performance for OER with an onset potential of 1.52 V (vs. the reversible hydrogen electrode, RHE) and a Tafel slope of 83 mV dec−1. The Co2Fe1 LDH was further loaded onto a Ni foam (NF) substrate to form a 3D porous architecture electrode, offering a long‐term current density of 100 mA cm−2 at 1.65 V (vs. RHE) towards the OER.

Published: February 2017

AbstractMedical grade 316L stainless steel was laser surface melted (LSM) using continuous wave Nd‐YAG laser in argon atmosphere at 1 and 5 mm/s. The treated surfaces were characterized using electron backscatter diffraction to study the influence of top surface crystallographic orientation and type of grain boundaries on corrosion resistance, wettability, and biocompatibility. The laser scan velocity was found to have a marginal influence on the surface roughness and the type of grain boundaries. However, the crystal orientation density was found to be relatively high in 1 mm/s samples. The LSM samples showed a higher concentration of {101} and {123} planes parallel to the sample surface as well as a higher fraction of low‐angle grain boundaries. The LSM samples were found to exhibit better surface wettability and enhanced the viability and proliferation of human fetal osteoblast cells in vitro when compared to the untreated samples. Further, the corrosion protection efficiency of 316L stainless steel was improved up to 70% by LSM in as‐processed condition. The increased concentration of {101} and {123} planes on surfaces of LSM samples increases their surface energy, which is believed to be responsible for the improved in vitro cell proliferation. Further, the increased lattice spacing of these planes and high concentration of low‐energy grain boundaries in LSM samples would have contributed to the better in vitro corrosion resistance than untreated 316L stainless steel. Our results indicate that LSM can be a potential treatment option for 316L stainless steel‐based biomedical devices to improve biocompatibility and corrosion resistance. © 2017 Wiley Periodicals, Inc.

Getting away from them all: Managing exhaustion from social interaction with telework
Authors: Windeler Jaime B. , Chudoba Katherine M. , Sundrup Rui Z. 
Published: February 2017

SummaryDrawing on the conservation of resources and recovery literatures, we examine how social job characteristics—interpersonal interaction, job interdependence, and external interaction—relate to work exhaustion. We then explore the efficacy of a part‐time telework (PTT) practice in alleviating work exhaustion associated with social interaction. Study 1 is a within‐subject assessment of work exhaustion before and after a PTT practice; participants are 51 information technology professionals in a financial services firm. Study 2 is a between‐subject assessment of work exhaustion among part‐time teleworkers and non‐teleworkers; participants are 258 U.S. workers spanning a variety of industries. Study 2 replicated the model tested in Study 1, and we extended the conceptualization of interpersonal interaction to examine both quantity and quality of interaction. In both studies, PTT provided a recovery opportunity, attenuating the relationship between interpersonal interaction and work exhaustion; however, after PTT but not before, work exhaustion increased as external interaction increased. In Study 2, work exhaustion decreased as interaction quality increased; in contrast, work exhaustion increased as interaction quantity increased and PTT attenuated this relationship. Our recommendations aim to help balance telework practices in light of social job characteristics and their opposing effects on work exhaustion. Copyright © 2017 John Wiley & Sons, Ltd.

Published: February 2017

The separation of ten epimeric aromatic acid (−)‐menthol esters by countercurrent chromatography with hydroxypropyl‐β‐cyclodextrin as the mobile phase additive was investigated, and methods for the analysis of all the epimeric esters by reversed‐phase high‐performance liquid chromatography were established. A biphasic solvent system composed of n‐hexane/20–70% methanol containing 50 mmol/L of hydroxypropyl‐β‐cyclodextrin (1:1, v/v) was selected, which provided high separation factors for five of the epimeric esters, and successful separations by countercurrent chromatography were achieved. The complete separation of five pairs of epimeric ester was obtained with the purity being over 98% for each peak fractions, as determined by high‐performance liquid chromatography. The recovery of each analyte from the eluted fractions reached around 80–88%.

Published: February 2017

Visible light curing of photopolymers has gained increasing interest in recent years. Dental materials are one of the important areas of application, where the bimolecular camphorquinone/amine initiator system is currently state of the art initiator. In this study, the authors describe the synthesis and photochemistry of tetrakis(2,4,6‐trimethylbenzoyl)silane, as cleavable Type I visible light photoinitiator. Besides excellent photobleaching behavior, this photoinitiator can well compete with up to now used long wavelength initiators.

AIMSTo characterize the urinary incontinence observed in adult Gli2+/−; Gli3Δ699/+ female mice and identify the defects underlying the condition.METHODSGli2+/− and Gli3Δ699/+ mice were crossed to generate: wild‐type, mutant Gli2 (Gli2+/−), mutant Gli3 (Gli3Δ699/+), and double mutant (Gli2+/−; Gli3Δ699/+) female mice, verified via Polymerase Chain Reactions. Bladder functional studies including cystometrogram (CMG), leak point pressure (LPP), and voiding testing were performed on adult female mice. Female bladders and urethras were also analyzed via ink injection and histological assays.RESULTSCMG tracing showed no signal corresponding to the filling of the Gli2+/−; Gli3Δ699/+ bladders. LPP were significantly reduced in Gli2+/−; Gli3Δ699/+ mice compared to wild‐type mice. CMG studies revealed a decrease in peak micturition pressure values in Gli2+/−; Gli3Δ699/+ mice compared with all other groups. No significant differences between mutant and wild‐type mice were detected in urinary output. Histological analyses revealed Gli2+/−; Gli3Δ699/+ mice exhibited a widened urethra and a decrease in smooth muscle layer thickness in the bladder outlet and urethra, with increased mucosal folding.CONCLUSIONSGli2+/−; Gli3Δ699/+ adult female mice display persistent urinary incontinence due to the malformation of the bladder outlet and urethra. This presents a consistent and reliable genetic mouse model for female urinary incontinence and alludes to the key role of genetic factors involved in the condition.
Ascitic fluid drainage using a peritoneal dialysis catheter to prevent and treat multi‐organ dysfunction in veno‐occlusive disease in children undergoing hematopoietic stem cell transplantation

Published: February 2017

AbstractVeno‐occlusive disease (VOD), or sinusoidal obstruction syndrome, is a well‐recognised, serious complication associated with the chemotherapy conditioning therapy used in hematopoietic stem cell transplantation (HSCT). Fluid management is typically challenging in children with this condition. We describe effective early use of peritoneal dialysis catheters to drain extravascular, intra‐abdominal fluid in children with VOD, allowing intravascular fluid administration to preserve renal perfusion and function, preventing multi‐organ dysfunction. All but one of the children are long‐term survivors, both of their significant VOD and their HSCT. The child that did not survive died from their underlying metabolic illness, not VOD.

AbstractPrevious studies have reported several cases of juvenile myelomonocytic leukemia (JMML) developing blastic transformation during an indolent clinical course, but the underlying mechanism of transformation is still not well understood. In this report, we describe a case of JMML with blastic transformation possibly caused by additional copy number gains of the KRAS mutant allele. We have discovered that the copy number gain of the mutant allele is an additional possible cause of blastic transformation in JMML.

AbstractWe reconstructed the centennial climate changes for the period of 9–7 cal ka BP in the upper region of the Changjiang (Yangtze) River Delta plain. A general warming and wetting trend from 8560 to 7220 cal yr BP was indicated by the decrease inQuercus(deciduous) and increases inQuercus(evergreen),Pinus, and Polypodiaceae spores. However, there were several brief climate fluctuations. A notable palynological change, from regional assemblages dominated by arboreal pollen to local assemblages mainly consisting of nonarboreal pollen, reflects climate fluctuations. The key indices ofQuercus(deciduous),Pinus, herbs, fern spores, and palynological concentrations showed similar signs of centennial climate fluctuations. We suggest that the climate changes of the Dongge Cave and Yangtze River Delta regions were mainly affected by the East Asian summer monsoon (EASM) during the period of 9–7 cal ka BP. The general warming trend may be associated with an intensified EASM, and solar activity may be one of the important factors driving the centennial climate changes. The ~8.2 ka event was also recorded in the Yangtze River Delta region, which suggests that there was a close relationship between the EASM and Greenland climate during the early Holocene.
Botanical Gardens and their Role in the Political Economy of Empire: Jamaica (1846–86)
Authors: TAYLOR DUNCAN 
Published: February 2017

Abstract:A variety of plants were distributed across Jamaica from the island's botanical gardens during the second half of the nineteenth century. This work became increasingly important over the period dating from 1846 to the end of the century when succeeding superintendents (subsequently directors) eagerly promoted the scheme. Yet, each head differed in their reasons to send out this ‘useful’ flora. In this article I consider the three men in charge of the public gardens from 1846 to 1886 and the context in which they decided that local plant distribution was important to pursue. Diversification of economic crops occurred, despite the plantocracy arguing that sugar and a few other plantation plants were the be all and end all of the Jamaican agricultural economy. By contextualising this activity we can tentatively start to unpick the role of minor officials in colonial life and the development of an aim to enrol the island's petty agriculturalist in particular economies calibrated around ideas of free trade, class and ‘race’.

AbstractThe identification of a stem cell regulatory gene which is aberrantly expressed in glioma and associated with patient survival would increase the understanding of the role of glioma cancer stem cells (GCSCs) in the virulence of gliomas. Interrogating the genomes of over 4000 brain cancers we identifiedZEB1deletion in ~15% (grade II and III) and 50% of glioblastomas. Meta-analysis ofZEB1copy number status in 2,988 cases of glioma revealed disruptiveZEB1deletions associated with decreased survival. We identifiedZEB1binding sites within the LIF (stemness factor) promoter region, and demonstrate LIF repression by ZEB1. ZEB1 knockdown in GCSCs causedLIFinduction commensurate with GCSC self-renewal and inhibition of differentiation. IFN-γ treatment to GCSCs induced ZEB1 expression, attenuating LIF activities. These findings implicateZEB1as a stem cell regulator in glioma which when deleted leads to increased stemness, tumorigenicity and shortened patient survival.

Triphenylammonium tricyanomethanide (Ph3NH)[C(CN)3] was synthesized and used as an efficient and recyclable nanostructured molten-salt (NMS) catalyst for the synthesis of N-benzylidene-2-arylimidazo[1,2-a]pyridin-3-amines by the reaction of various (het)aryl aldehydes with trimethylsilyl cyanide and pyridin-2-amine under solvent-free conditions at 50 °C. The NMS catalyst could be simply recycled and reused several times without significant loss of its catalytic activity.

Significance
The molecular mechanism for sealing newly formed nuclear envelopes was unclear until the recent discovery that endosomal sorting complexes required for transport III (ESCRT-III) proteins mediate this process. Cmp7p (CHMP7), in particular, was identified as an early acting factor that recruits other ESCRT-III proteins to the nuclear envelope. A fundamental aspect of the varied roles of ESCRT factors is their recruitment by site-specific adaptors, yet the central question of how the ESCRT machinery is targeted to nuclear membranes has remained outstanding. Our study identifies the inner nuclear membrane protein LEM2 as a key, conserved factor that recruits CHMP7 and downstream ESCRT-III proteins to breaches in the nuclear envelope.
Specific phospholipid binding to Na,K-ATPase at two distinct sites
Authors: Habeck Michael , Kapri-Pardes Einat , Sharon Michal , Karlish Steven J. D. 
Published: February 2017

Significance
Activity and structural integrity of membrane proteins can be regulated by physical properties of the bilayer or specific lipid–protein interactions. This work shows that key properties of the Na,K-ATPase are modulated independently by specific binding of 18:0/18:1 phosphatidylserine (PS) and 18:0/20:4 phosphatidylcholine (PC) in the absence of a bilayer. PS stabilizes the protein, and PC/ phosphatidylethanolamine (PE) stimulates Na,K-ATPase activity. We characterized effects of both types of phospholipids by kinetic approaches, mutant analyses, and native MS. Modulation of Na,K-ATPase function by PS and PC/PE is defined by the phospholipid structural specificity, binding stoichiometry within two specific binding sites, and the kinetic mechanism. We provide detailed mechanistic insights, potentially with important implications for physiological regulation of active Na and K transport.
Ingmar Bergman
Authors: Hedling Erik 
Published: February 2017

Swedish director Ingmar Bergman (b. 1918–d. 2007) was probably one of the most prominent filmmakers of the twentieth century. He started his career in film as a scriptwriter for Alf Sjöberg’s film Hets (released as Torment in the United States and as Frenzy in the United Kingdom) in 1944 and made his debut as a director with Kris (Crisis) in 1946. He continued making films through the 1940s, 1950s, 1960s, and 1970s and directed his last film for distribution in the cinemas in 1982: his grand finale, Fanny och Alexander (Fanny and Alexander). He did, however, go on as a scriptwriter and literary author. He also directed a few works for television until 2003, four years before his death at the age of eighty-nine. During all this time he was also active as a highly appreciated theater director, setting up plays primarily at the Royal Dramatic Theatre (Kungliga Dramatiska Teatern) in Stockholm. But it is mainly as the director of a series of highly influential films that his international reputation rests, films for which he usually wrote the manuscripts himself. Among his oeuvre, we find several of the masterpieces of postwar cinema: the dark vision of humanity in the classic Det sjunde inseglet (The Seventh Seal, 1957), the austere modernism in Persona (1966), the brilliantly staged marital conflict in his TV series Scener ur ett äktenskap (Scenes from a Marriage, 1973), and the somewhat unexpected celebration of bourgeois life in Fanny and Alexander. In film-historical terms, Bergman’s works were seminal to the development of the European art cinema, le cinéma d’auteur, in the 1950s. It was also in France that he became internationally famous after the screening of his light comedy Sommarnattens leende (Smiles of a Summer Night, 1955) at the Cannes Film Festival in 1956, where it received the highly coveted Special Jury Prize. After this great success, Bergman was canonized by the writers of influential French film journal Cahiers du Cinéma. Later, he would receive three Academy Awards for Best Foreign Language Film: for Jungfrukällan (The Virgin Spring, 1960) in 1961, Såsom i en spegel (Through a Glass Darkly, 1961) in 1962, and Fanny and Alexander in 1983. Bergman has often been quoted as a prime influence by leading film directors such as Jean-Luc Godard, François Truffaut, Woody Allen, Lars von Trier, and Ang Lee. He is also one of the most chronicled of all film directors, with an almost endless amount of monographs and scholarly articles written about his works; works on Bergman are still published every year, some of them major ones. His constant themes were the torments of the human soul, the absentness of God, and the humiliation that according to his vision forms the basis of the human condition. His cinematic forms, initially classical in style, grew gradually more toward aesthetic experimentation and modernism in the 1960s, with a return to popular narrative forms in the 1970s and 1980s.
Contralateral Anterior Interhemispheric Approach to Medial Frontal Arteriovenous Malformations: Surgical Technique and Results
Authors: Hafez Ahmad , Raygor Kunal P. , Lawton Michael T. 
Published: February 2017

Abstract

BACKGROUND: Medial frontal arteriovenous malformations (AVMs) require opening the interhemispheric fissure and are traditionally accessed through an ipsilateral anterior interhemispheric approach (IAIA). The contralateral anterior interhemispheric approach (CAIA) flips the positioning with the midline still positioned horizontally for gravity retraction, but with the AVM on the upside and the approach from the contralateral, dependent side.

OBJECTIVE: To determine whether the perpendicular angle of attack associated with the IAIA converts to a more favorable parallel angle of attack with the CAIA.

METHODS: The CAIA was used in 6 patients with medial frontal AVMs. Patients and AVM characteristics, as well as pre- and postoperative clinical and radiographic data, were reviewed retrospectively.

RESULTS: Four patients presented with unruptured AVMs, with 5 AVMs in the dominant, left hemisphere. The lateral margin was off-midline in all cases, and average nidus size was 2.3 cm. All AVMs were resected completely, as confirmed by postoperative catheter angiography. All patients had good neurological outcomes, with either stable or improved modified Rankin Scores at last follow-up.

CONCLUSIONS: This study demonstrates that the CAIA is a safe alternative to the IAIA for medial frontal AVMs that extend 2 cm or more off-midline into the deep frontal white matter. The CAIA aligns the axis of the AVM nidus parallel to the exposure trajectory, brings its margins in view for circumferential dissection, allows gravity to deliver the nidus into the interhemispheric fissure, and facilitates exposure of the lateral margin for the final dissection, all without resecting or retracting adjacent normal cortex.

Published: February 2017

Objectives:
This case report aims to help healthcare providers and methadone clinic patients to recognize one of the less recognized adverse effects of methadone, hyperhidrosis, and to suggest oxybutynin as a possible solution.

Methods:
A 35-year-old man on methadone maintenance therapy presented with excessive sweating, which began promptly after methadone was introduced. Urine toxicology was conducted every 2 weeks to rule out other illicit substances that may have contributed to the sweating.

Results:
Oxybutynin (5 mg PO QID) resulted in cessation of the methadone-induced hyperhidrosis within 2 days of starting the medication.

Conclusions:
Methadone-induced excessive sweating is an adverse effect of the medication that reportedly affects up to 45% of those prescribed methadone, and oxybutynin is a potent treatment for methadone-induced excessive sweating.

Published: February 2017

Abstract:
Actinic granuloma and annular elastolytic giant cell granuloma are variants of granuloma annulare affecting, respectively, sun-exposed and sun-covered skin sites on where, besides classical findings, abundant elastophagocytosis is observed. Here, we report a case of exuberant actinic granuloma annulare that, in addition to extensive scarring, showed multiple overlying open comedones. Markedly dilated follicular infundibula filled with compact masses of laminated keratinous material were observed in proximity to dermal inflammation composed of many histiocytes and multinucleated giant cells in close association with degenerated elastic fibers and abundant elastophagocytosis.
