AbstractThis study reports the facile preparation and the dye removal efficiency of nanohybrids composed of graphene oxide (GO) and Fe3O4 nanoparticles with various geometrical structures. In comparison to previously reported GO/Fe3O4 composites prepared through the one-pot, in situ deposition of Fe3O4 nanoparticles, the GO/Fe3O4 nanohybrids reported here were obtained by taking advantage of the physical affinities between sulfonated GO and Fe3O4 nanoparticles, which allows tuning the dimensions and geometries of Fe3O4 nanoparticles in order to decrease their contact area with GO, while still maintaining the magnetic properties of the nanohybrids for easy separation and adsorbent recycling. Both the as-prepared and regenerated nanohybrids demonstrate a nearly 100% removal rate for methylene blue and an impressively high removal rate for Rhodamine B. This study provides new insights into the facile and controllable industrial scale fabrication of safe and highly efficient GO-based adsorbents for dye or other organic pollutants in a wide range of environmental-related applications.

AbstractPolycystic ovary syndrome (PCOS) is a complex endocrine disorder that is proposed to have a genetic basis. A recent genome-wide association study (GWAS) identified eight new risk loci that are independently associated with PCOS. To further validate the findings, a total of 321 case-parent trios (963 participants) who had a proband affected with PCOS were recruited for the family-based study. The transmission disequilibrium test (TDT) was used to analyze associations between PCOS and ten single nucleotide polymorphisms (SNPs) mapped to eight new susceptibility loci. Significant differences in transmission were observed for the SNPs rs2349415 (located in the FSHR gene, P = 0.0001) and rs3802457 (located in the C9orf3 gene, P = 0.0001), even after correction for multiple testing bias. The present data provides further evidence for an association between two susceptibility loci, 2p16.3 and 9q22.32 and PCOS. Follow-up functional studies on the FSHR and C9orf3 genes are required to understand their roles in PCOS development.
Genome-wide analysis of enhancer RNA in gene regulation across 12 mouse tissues

Published: July 2015

AbstractEnhancers play a crucial role in gene regulation but the participation of enhancer transcripts (i.e. enhancer RNA, eRNAs) in regulatory systems remains unclear. We provide a computational analysis on eRNAs using genome-wide data across 12 mouse tissues. The expression of genes targeted by transcribing enhancer is positively correlated with eRNA expression and significantly higher than expression of genes targeted by non-transcribing enhancers. This result implies eRNA transcription indicates a state of enhancer that further increases gene expression. This state of enhancer is tissue-specific, as the same enhancer differentially transcribes eRNAs across tissues. Therefore, the presence of eRNAs describes a tissue-specific state of enhancer that is generally associated with higher expressed target genes, surmising as to whether eRNAs have gene activation potential. We further found a large number of eRNAs contain regions in which sequences and secondary structures are similar to microRNAs. Interestingly, an increasing number of recent studies hypothesize that microRNAs may switch from their general repressive role to an activating role when targeting promoter sequences. Collectively, our results provide speculation that eRNAs may be associated with the selective activation of enhancer target genes.

Authors: Boni A. , Tonelli M. , Magnanini A. , Caselli M. 
Published: July 2015

The voltage signal at the output of the power device driving the ignition coil or the fuel injector of a car engine is often required to be detected and processed for control and diagnostic purposes. Providing this kind of signals to an integrated circuit raises several design and reliability issues due to the presence of voltage peaks of several hundred volts. The design and implementation of an integrated detection and overvoltage protection circuit is presented. A prototype chip was implemented in a 350 nm CMOS technology without a thick‐oxide option. The measured performance over the −40 to +125°C temperature range is in good agreement with the simulation results.
Preventing hydrogen embrittlement in stainless steel by means of compressive stress induced by cavitation peening
Authors: Takakuwa Osamu , Soyama Hitoshi 
Published: July 2015

In this paper, it has been demonstrated that compressive residual stress induced by cavitation peening which is one of the mechanical surface modification techniques can reduce invasion of the surface of austenitic stainless steel by hydrogen. Cavitation peening was done with employing a cavitating jet in air. The specimens were prepared with different processing time of cavitation peening. Then, stress measurement was performed using an X‐ray diffraction analysis. After that, the surface was charged with hydrogen employing a cathodic charging method. Hydrogen content was evaluated by a thermal desorption analysis using a gas chromatography. From the obtained results, hydrogen content was reduced along with increase in compressive residual stress at surface. In particular hydrogen content became to 15% at processing time of 2 s/mm introducing compressive residual stress of 378 MPa. In short, cavitation peening can drastically prevent invasion by hydrogen.

Laser Shock Peening is a fatigue enhancement treatment using laser energy to induce compressive Residual Stresses (RS) in the outer layers of metallic components. This work describes the variations of introduced RS‐field with peen size and coverage for thin metal samples treated with under‐water‐LSP. The specimens under investigation were of aluminium alloy AA2024‐T351, AA2139‐T3, AA7050‐T76 and AA7075‐T6, with thickness 1.9 mm. The RS were measured by using Hole Drilling with Electronic Speckle Pattern Interferometry and X‐ray Diffraction. Of particular interest are the effects of the above mentioned parameters on the zero‐depth value, which gives indication of the amount of RS through the thickness, and on the value of the surface compressive stresses, which indicates the magnitude of induced stresses. A 2D‐axisymmetrical Finite Element model was created for a preliminary estimation of the stress field trend. From experimental results, correlated with numerical and analytical analysis, the following conclusions can be drawn: increasing the spot size the zero‐depth value increases with no significant change of the maximum compressive stress; the increase of coverage leads to significant increase of the compressive stress; thin samples of Al‐alloy with low Hugoniot Elastic Limit (HEL) reveal deeper compression field than alloy with higher HEL value.
Membrane topology of Golgi-localized probable S-adenosylmethionine-dependent methyltransferase in tobacco (Nicotiana tabacum) BY-2 cells
Authors: Liu Jianping , Hayashi Kyoko , Matsuoka Ken 
Published: July 2015

Abstract
S-adenosylmethionine (SAM)-dependent methyltransferases (MTases) transfer methyl groups to substrates. In this study, a novel putative tobacco SAM-MTase termed Golgi-localized methyl transferase 1 (GLMT1) has been characterized. GLMT1 is comprised of 611 amino acids with short N-terminal region, putative transmembrane region, and C-terminal SAM-MTase domain. Expression of monomeric red fluorescence protein (mRFP)-tagged protein in tobacco BY-2 cell indicated that GLMT1 is a Golgi-localized protein. Analysis of the membrane topology by protease digestion suggested that both C-terminal catalytic region and N-terminal region seem to be located to the cytosolic side of the Golgi apparatus. Therefore, GLMT1 might have a different function than the previously studied SAM-MTases in plants.

AbstractIn rugby union, understanding the techniques and events leading to concussions is important because of the nature of the injury and the severity and potential long‐term consequences, particularly in junior players. Proper contact technique is a prerequisite for successful participation in rugby and is a major factor associated with injury. However, the execution of proper contact technique and its relationship to injury has yet to be studied in matches. Therefore, the aim of this study was to compare contact techniques leading to concussion with a representative sample of similarly matched non‐injury (NI) contact events. Injury surveillance was conducted at the 2011–2013 under‐18 Craven Week Rugby tournaments. Video footage of 10 concussive events (5 tackle, 4 ruck and 1 aerial collision) and 83 NI events were identified (19 tackle, 61 ruck and 3 aerial collisions). Thereafter, each phase of play was analysed using standardised technical proficiency criteria. Overall score for ruck proficiency in concussive events was 5.67 (out of a total of 15) vs. 6.98 for NI events (n = 54) (effect size = 0.52, small). Overall average score for tackler proficiency was 7.25 (n = 4) and 6.67 (n = 15) for injury and NI tackles, respectively (out of 16) (effect size = 0.19, trivial). This is the first study to compare concussion injury contact technique to a player‐matched sample of NI contact techniques. Certain individual technical criteria had an effect towards an NI outcome, and others had an effect towards a concussive event, highlighting that failure to execute certain techniques may substantially increase the opportunity for concussion.

Published: July 2015

Abstract
The numerous merits of conjugated polymers (CPs) have encouraged scientists to develop a variety of synthetic routes to CPs with diverse structures and functionalities. Among the large scope of substrates, alkyne plays an important role in constructing polymers with conjugated backbones. In addition to some well-developed reactions including Glaser–Hay and Sonogashira coupling, azide/thiol-yne click reaction and cyclotrimerization, some novel alkyne-based reactions have also been explored such as oxidative polycoupling, decarbonylative polycoupling and multicomponent tandem polymerizations. This review focuses on the recent progress on the synthetic methodology of CPs in the last five years using monomers with two or more triple bonds and some of their high-technological applications. Selected examples of materials properties of these CPs are given in this review, such as fluorescence response to chemical or physical stimuli, magnetism, white light emission, cell imaging and bioprobing. Finally, a short perspective is raised in regard to the outlook of the preparation methodologies, functionalities as well as potential applications of CPs in the future.
Radiologic, Neurologic and Cardiopulmonary Aspects of Submersion Injury

Published: July 2015

Abstract
Many indices and scores are used in critical care medicine to aid management and predict risk of mortality. We report 2 cases of submersion injury and discuss the usefulness and application of common respiratory and critical care indices. The respiratory indices help better understand the pulmonary pathophysiology and characterize the severity of lung injury and ventilation/perfusion mismatch. Severe lung injury resolved after ventilation support with appropriate positive end-expiratory pressure in both cases. The 6-year-old girl survived the near-fatal submersion injury intact despite grossly abnormal initial Glasgow Coma Scale (GCS) and high Pediatric Index of Mortality 2 scores, whereas the 5-year-old boy with grossly abnormal GCS and Pediatric Index of Mortality 2 scores died despite resolution of lung injury. These cases illustrate that resuscitation should be promptly instituted at the scene to ensure optimal outcome because initial pulmonology and neurology indices may not reliably predict mortality or intact survival. The GCS score was not initially designed for prognostication. Nevertheless, 2 serial GCS scores of 3, one performed at emergency department and one at the pediatric intensive care unit, were associated with nonsurvival in our second patient.
A Curiously Rare Case of Septic Shock From Clostridium difficile Colitis
Authors: Loftus Kirsten Virginia , Wilson Paria Majd 
Published: July 2015

Abstract
This case provides the first report of a young healthy child presenting in septic shock from Clostridium difficile colitis. This child had no identifiable risk factors for C. difficile, raising the suspicion for a hypervirulent strain. Once infection was recognized and treated appropriately, the child made a full recovery. This case presentation highlights the need to consider C. difficile colitis in the differential diagnosis of severely ill patients, even in the absence of traditional risk factors or symptoms.
Female Adolescent Presenting With Abdominal Pain
Authors: Di Guglielmo Matthew , Savage Jillian , Gould Sharon , Murphy Stephen 
Published: July 2015

Introduction
Abdominal pain in female adolescents is a common presentation to both the emergency department and the outpatient pediatric clinic. The broad differential diagnosis for abdominal pain requires a high index of suspicion to make an accurate diagnosis of foreign body ingestion as the etiology. Foreign body ingestion occurs in all age groups, but sequelae of gastrointestinal tract perforation in children are rare. Treatment for perforation requires consultation of the pediatric general surgeon. Clinicians should take care to not overlook subtle imaging findings or dietary/exposure history, even in the context of a patient with known history of abdominal pain.

Case Report/Technique Description
We report the accidental ingestion of a wire bristle from a grill cleaning brush by a female adolescent. The patient, previously treated and seen for constipation and irritable bowel syndrome in the outpatient gastroenterology clinic, was referred to the emergency department after identification of a foreign body on abdominal radiography. Emergency department physicians discovered the history of grilling and consumption of grilled food, facilitating diagnosis of a wire bristle as the foreign body. The metallic foreign body had migrated to the colon, where it perforated and lodged into the abdominal wall, causing acute, focal symptoms. Observation in the hospital with pain control and infection management allowed for elective laparoscopy. The surgical team removed the object with minimal morbidity and avoided laparotomy.

Discussion
Reports of unintended ingestion of wire bristles have been increasingly reported in the literature; however, most focus on injury to the upper airway or upper digestive tract and subsequent endoscopic or laryngoscopic removal. Most reports detail injury in adult patients, pediatric case reports with digestive tract injury are uncommon, and foreign body removal after lower digestive tract injury in children from a wire bristle has not been reported. We caution pediatric emergency medicine and ambulatory providers to consider such an ingestion and perforation in the differential diagnosis of acute-onset, focal, and localizable abdominal pain in children.

AbstractPlant biology is rapidly entering an era where we have the ability to conduct intricate studies that investigate how a plant interacts with the entirety of its environment. This requires complex, large studies to measure how plant genotypes simultaneously interact with a diverse array of environmental stimuli. Successful interpretation of the results from these studies requires us to transition away from the traditional standard of conducting an array of pairwise t tests toward more general linear modeling structures, such as those provided by the extendable ANOVA framework. In this Perspective, we present arguments for making this transition and illustrate how it will help to avoid incorrect conclusions in factorial interaction studies (genotype × genotype, genotype × treatment, and treatment × treatment, or higher levels of interaction) that are becoming more prevalent in this new era of plant biology.
Does oil consumption promote economic growth in oil producers?
Authors: Alberto Fuinhas Jose , Cardoso Marques Antonio , Quaresma Tânia Noélia 
Published: July 2015

Purpose
The oil-growth nexus is studied in a panel of Organization of the Petroleum Exporting Countries (OPECs), for a long time span (1960-2011), controlling for the specific context of oil production. Their membership in the cartel put them under a common guidance, which originates phenomena of cross-section dependence/contemporaneous correlation in the panel.

Design/methodology/approach
Recent panel data estimators and co-integration analyses are both pursued and discussed, namely, dealing with the heterogeneity of panels and the countries’ specific effects. The Driscoll–Kraay estimator proves to be appropriate in handling the panel properties.

Findings
Full understanding of the oil-growth nexus requires the short- and long-run effects to be broken down. The growth hypothesis was found only in the short run. The results suggest the presence of the resource curse phenomenon and prove that the cartel’s long-run growth goal could not being fully accomplished. Actually, both oil production and prices are not promoting economic growth in OPEC countries.

Originality/value
The focus is on a group of countries which, besides being oil exporters, have an institutional connection between them, i.e. the OPEC cartel. The paper also contributes by framing the relationship between oil consumption and economic growth within a context of countries that are primary energy producers. Additionally, the paper uses a novel econometric approach and a long time span (52 years) not tested.
Investigations about new methods of library marketing in Chinese “985” Project Universities
Authors: Hua Xiaoqin , Si Li , Zhuang Xiaozhe , Xing Wenming 
Published: July 2015

Purpose
– Under the new technological environment, academic libraries meet an extremely intense competition in offering information services, and marketing becomes an important means to attain the goal of their sustainable development. The purpose of this paper is to get an overview of library marketing in Chinese “985” Project Universities, the authors undertook a survey on each library of “985” Project Universities released on the web site of Ministry of Education of the People’s Republic of China. And then the authors identified some successful practices based on the survey.

Design/methodology/approach
– First, the content of each web site, along with the individual hyperlinks and categories that every library web site has, were browsed to check the availability of the categories. Second, the search function of each library was explored using terms like “blog,” “video” and “tutorial” to retrieve information about services. Third, the Google search engine was used to retrieve information from Renren, microblog and YouTube accounts combining with the name of each library. And then the authors consult reference librarians about marketing methods and tools applied in their libraries with real-time online reference services.

Findings
– This paper suggests that 29 libraries are exploiting video marketing, which is the most widely used marketing methods, accounting for 74.36 percent. Mobile library marketing and microblog marketing are another two major application among the 39 “985” Project Universities libraries in China, respectively, accounting for 69.23 and 58.97 percent.

Originality/value
– The paper reveals that there are some deficiencies lying in the marketing of these libraries: characteristic resources in really simple syndication (RSS) are insufficient, video themes turn to be traditional and plain, network media marketing is relatively uncommon, and mobile library marketing is limited to mobile messaging services. It may fill in the gap of better understanding the relationship between the traditional information services and modern services from users’ perspective. It is instructive for libraries to systematically summarize success or failure experience of other library marketing, and keep an innovative concept and global vision.
Social capital and leadership in academic libraries: the broader exchange around “Buy In”
Authors: Schlak Timothy M. 
Published: July 2015

Purpose– The purpose of this paper is to introduce the concept of social capital to the literature on academic libraries as it pertains to leadership and management as well as to demonstrate the limitations that the current discursive use of the phrase “buy in” represents.Design/methodology/approach– This paper brings critical insights from outside fields of intellectual inquiry, including business, knowledge management, computer and information systems, and sociology. The paper is organized around a series of questions posed at the end of the introduction and serves to introduce its audience to the key findings made in these fields as well as to apply relevant observations about social capital to the unique context of leadership and management in academic libraries.Findings– The paper elucidates a number of limitations to the current practice of using the phrase “buy in” as a way of exploring the concept of social capital. The most significant risk that the phrase’s use incurs is a lack of context and clarity around critical concepts of leadership, including trust, trustworthiness, and shared vision and meaning.Originality/value– This paper argues that a broader contextualization of “buy in” in the scholarship on social capital can lead to a richer dialog that allows academic library administrators to understand the concurrent and competing factors that accompany an exchange where “buy in” is given or withheld.
