Off‐flavors, characterized by a fishy odor, are emitted during the heating of rapeseed oil in a fryer. In order to study the headspace composition of degraded rapeseed oil, and more specifically the compounds responsible for the fishy odor, four headspace techniques were evaluated: Static headspace (SHS), headspace trap (HS Trap), headspace solid phase microextraction (HS‐SPME), and headspace sorptive extraction (HSSE) coupled to gas chromatography‐mass spectrometry (GC‐MS). The selected model compounds to develop the headspace methods were 1‐penten‐3‐one, 1‐octen‐3‐one, and E,Z‐2,6‐nonadienal as known fishy odor markers. Extraction conditions for the four techniques were optimized and evaluated in terms of repeatability and sensitivity. They were then applied to the analysis of real samples of degraded rapeseed oil. SHS was not suitable for the analysis of odorant volatile compounds because of LOD values lower than those required for a quantitative analysis of the target compounds. Concerning HS‐SPME and HSSE, a discrimination against the more volatile compounds was observed. Finally, HS Trap‐GC‐MS was considered the most appropriate technique for the analysis of the headspace of rapeseed oil in this study with LOD values less than 2 μg/L for the three target compounds. More than 60 compounds were identified by HS Trap‐GC‐MS and two compounds responsible for the fishy odor could be detected. The evolution of the relative areas of these compounds was reported for fresh oil and rapeseed oil degraded by 1, 5, and 10 heating cycles.Practical applications: The characterization of the volatile compounds responsible for the fishy odor is a key industrial issue. Moreover, the developed method with HS‐Trap could be used to quantify several volatile compounds characteristic of the degradation of rapeseed oil, and to evaluate the possible effect of antioxidants on oils.Rapeseed oil is edible oil containing a substantial amount of omega 3, but the heating of this oil leads to the formation of off‐flavors, characterized by a fishy odor. The characterization of these off‐flavors is a key industrial issue, and different headspace techniques can be considered to study the molecules present in the headspace of degraded rapeseed oil.

The Baltic Sea is one of the world's most pollution‐threatened brackish environments and limited direct consumption of fatty fish from the Baltic Sea is recommended. The use of decontaminated Baltic Sea fish raw materials as fish feed could be a strategy to recycle Baltic Sea nutrients back into food chain, while relieving pressure on aqua‐feed in the growing aquaculture industry. In this study, defatted fishmeal and semi‐purified fish oil from the Baltic Sea were used in fish feeds for Arctic char (Salvelinus alpinus L.). The effects of the Baltic Sea‐sourced fish feeds on flesh lipid quality and fish metabolomics, compared with a standard commercial feed as a control, were determined. 1H NMR‐based metabolomics studies indicated disturbances in energy metabolism and hepatic toxicity in fish fed both crude fishmeal and crude fish oil, associated with up‐regulation (IGF‐I, GHR‐I, PPARα, PPARβ1A) and down‐regulation (SREBP‐1 and FAS) of hepatic genes expression. The content of n‐3 long chain polyunsaturated fatty acids was not affected by the decontamination process. Thus, this short‐term study demonstrates that decontaminating Baltic Sea‐sourced fishmeal and fish oil reduces adverse effects in Arctic char.Practical applications: Decontaminated fish materials from the Baltic Sea were shown to be promising feed ingredients for Arctic char (Salvelinus alpinus L.) compared with untreated Baltic Sea‐sourced fish feed, which induced changes in fish physiology associated with energy metabolism and hepatotoxicity. Baltic Sea‐sourced fish materials containing high levels of long chain polyunsaturated fatty acids are valuable feed ingredients.The Baltic Sea‐sourced fishmeal (CFM and DFM) and fish oil (CFO and SPFO) were tested in fish feeds for Arctic charr (Salvelinus alpinus), compared with a commercial diet as a control. Flesh lipid quality, metabolic profile in liver and muscle and hepatic gene expression (IGF‐I, GHR‐I, SREBP‐1, etc.) were evaluated.

Published: September 2015

AbstractThe chemical compositions of essential oils of Lavandula angustifolia, Lavandula latifolia, Lavandula hybrida cultivar Grosso and cultivar Super, Thymus zygis with high proportions of thymol and linalool and Thymus hyemalis, from Murcia country (Spain), were studied in relative (%), absolute (mM) and chiral concentrations by GC/MS. Hyaluronidase inhibition and antioxidant activities of the essential oils were evaluated using ABTS•+, DPPH•, ORAC, chelating power, hydroxyl radical, nitric oxide, TBARS and reducing power assays. Linalool and linalyl acetate were the most abundant components in the Lavandula genus whereas thymol, linalool and 1,8‐cineole were the most abundant molecules in the respective Thymus species. Chiral determination of the main components showed (+)‐enantiomers like terpinen‐4‐ol, β‐pinene, borneol and α‐terpineol and (−)‐enantiomers like linalool, linalyl acetate and camphene in Lavandula sp. In the case of Thymus sp. (+)‐enantiomers like α‐pinene, limonene, terpinen‐4‐ol and α‐terpineol and (−)‐enantiomers like borneol were found. Essential oils containing thymol were found especially powerful in all assays but chelating power, ORAC and hydroxyl radical scavenging assays. The capacity for inhibiting hyaluronidase showed that T. zygis with a high proportion of thymol was the most effective inhibitor. Essential oils containing thymol and linalool/linalyl acetate have a potential use as antioxidant agents. Thymol shows strong inhibition of hyaluronidase. Copyright © 2015 John Wiley & Sons, Ltd.
Is the introduction of an accreditation program likely to generate organization‐wide quality, change and learning?
Authors: Lanteigne Gilles , Bouchard Chantal 
Published: September 2015

SummaryObjectiveThis research assesses whether integration of Accreditation Canada's program brings about change and organizational learning.MethodsTwo health organizations, the Health Authority of Anguilla and the Ca' Foncella Opetale di Treviso, are studied on three levels: (1) members; (2) accreditation teams; and (3) organization. The methods used to collect data consisted of individual questionnaires administered to team members, semi‐formal interviews with team leaders and quality coordinators, a documentation review and periodic assessments of compliance with the standards.ResultsThe findings indicate that the organizations made strategic, organizational and relational changes. They improved their systems and management practices as well as their internal and external communications. There was also useful learning by individuals, teams and the organizations. Individual learning involved quality practice, client‐focused approach, risk management, ethics, participatory management and assessment of services. The “self‐assessment” and “make improvements and follow up on recommendations” stages of the accreditation cycle contributed the most to change and organizational learning. The interdisciplinary accreditation teams were the preferred vehicle for achieving these changes and this learning.ConclusionsThe Health Authority of Anguilla and Ca' Foncella Opetale di Treviso have gradually improved their level of compliance with the standards in all quality dimensions. However, improvement in the overall compliance level was below the program's minimum requirements to obtain accreditation status without major restrictions. The scope of the changes and learning achieved raises the issue of the capacity of organizations to formalize this new knowledge throughout the organization. Copyright © 2015 John Wiley & Sons, Ltd.

Published: September 2015

AbstractStrength is one of the most important properties of cover glass. In this study, fracture analysis is used to classify the breakage mode of cover glass into four typical modes. Moreover, the mechanism and evaluation method of each mode are investigated. Consequently, a chemical strengthening design with high compressive stress (CS) and low center tension (CT) is obtained. In addition, processing design is determined to be an important factor. Fining of edge processing and surface polishing after chemical strengthening are shown to enhance the edge and surface strength, respectively.

Published: September 2015

AbstractIn this study, we have compared the performance of self‐aligned a‐IGZO thin‐film transistors (TFTs) whereby the source/drain (S/D) region's conductivity enhanced in three different ways, that is, using SiNx interlayer plasma (hydrogen diffusion), using calcium (Ca as reducing metal) and using argon plasma (changing the atomic ratio). All these TFTs show comparable characteristics such as field‐effect mobility (μFE) of over 10.0 cm2/(V.s), sub‐threshold slope (SS‐1) of 0.5 V/decade, and current ratio (ION/IOFF) over 108. However, under negative‐bias‐illumination‐stress (NBIS), all these TFTs showed strong degradation. We attributed this NBIS stability issue to the exposed S/D regions and changes in the conductivity of S/D contact regions. The hydrogen plasma‐treated TFTs showed the worst NBIS characteristics. This is linked to increased hydrogen diffusion from the S/D contact regions to the channel.

Objectives/HypothesisTo determine the effect of otolaryngology trainee participation on clinical outcomes in patients who undergo endoscopic sinus surgery (ESS) for chronic rhinosinusitis.Study DesignSecondary analysis of prospectively collected data.MethodsPatients enrolled in a sinus surgery outcomes study between May 2011 and March 2013 were stratified into two groups—those who were operated on by an attending alone and those operated on by an attending with a trainee present (resident, fellow, or both). Patients completed quality of life (QOL) surveys including the Chronic Sinusitis Survey (CSS), 22‐item Sino‐Nasal Outcome Test (SNOT‐22), and EuroQol 5‐dimension survey preoperatively and 1 year postoperatively. Operative time, estimated blood loss (EBL), complication rates, and survey scores were compared between groups.ResultsThe study population consisted of 452 patients. The attending alone (n = 119) and trainee (n = 333) groups were statistically comparable in terms of patient demographics, disease severity, and extent of surgery. Mean operative time was significantly shorter in the attending‐alone group (80.0 vs. 90.6 minutes, P < .01). Mean EBL (105 mL attending vs. 117 mL trainee, P = .39) and complication rates (3.3% attending vs. 0.6% trainee, P = .07) were similar between groups. Observed changes in QOL measures following ESS were comparable between groups, although absolute improvement in the SNOT‐22 scores (19.0 attending vs. 24.5 trainee, P = .05) did show a trend toward greater improvement in the trainee group.ConclusionsTrainee participation in ESS is associated with prolongation in surgical time; however, such participation was not found to adversely affect patient safety or clinical outcomes.Level of Evidence2b Laryngoscope, 126:316–321, 2016
The missing piece: cancer prevention within psycho‐oncology — a commentary
Authors: Rosberger Zeev , Perez Samara , Bloom Joan , Shapiro Gilla K. , Fielding Richard 
Published: September 2015

AbstractIn this commentary, we review the place of prevention within the field of Psycho‐Oncology. The thrust of Psycho‐Oncology's clinical and research efforts have historically focused on behavioral and social factors implicated in the cancer patients' experience from detection and diagnosis, to treatment, survivorship and end of life along the cancer trajectory. This conceptualization has raised the standards for research, leading to a better understanding of the patient experience and the delivery of highly effective interventions to improve quality of life. Emerging data on the role of potential prevention behaviors (e.g., diet and exercise, smoking cessation, screening, etc.) suggests that Psycho‐Oncology has a significant role to play in understanding and intervening on a population level to reduce cancer incidence. We present and describe an expanded model of research in Psycho‐Oncology which incorporates psychosocial variables in prevention research to complement Holland et al.'s (1998, 2010) original model. The implications of this model are discussed in relation to research, clinical work and training within the discipline of Psycho‐Oncology. Copyright © 2015 John Wiley & Sons, Ltd.
Stranger than fiction in the archives: The controversial death of William Cowbridge in 1538
Authors: Freeman Thomas S. , Royal Susan 
Published: September 2015

AbstractThis essay considers the life, death, and afterlife of William Cowbridge a religious eccentric executed for heresy in 1538. It explores the significance of his religious beliefs, which became the source of a heated controversy between the Protestant martyrologist John Foxe and the Catholic polemicist Nicholas Harpsfield. The case casts light on a range of issues, including the dynamic between Protestant and Catholic controversialists, the use of the label of ‘madness’ in argument, and the value of archival documentation alongside the use of oral sources in Reformation-era polemic. It also yields insight into Thomas Cromwell’s authority over the English Church during the late 1530s, and highlights his position among Henrician evangelicals as a source of influence and aid. Finally, it offers a critique about interpretations of early modern belief and the designation of the label ‘Lollard’.
16Stimator: statistical estimation of ribosomal gene copy numbers from draft genome assemblies
Authors: Perisin Matthew , Vetter Madlen , Gilbert Jack A , Bergelson Joy 
Published: September 2015

Abstract
The 16S rRNA gene (16S) is an accepted marker of bacterial taxonomic diversity, even though differences in copy number obscure the relationship between amplicon and organismal abundances. Ancestral state reconstruction methods can predict 16S copy numbers through comparisons with closely related reference genomes; however, the database of closed genomes is limited. Here, we extend the reference database of 16S copy numbers to de novo assembled draft genomes by developing 16Stimator, a method to estimate 16S copy numbers when these repetitive regions collapse during assembly. Using a read depth approach, we estimate 16S copy numbers for 12 endophytic isolates from Arabidopsis thaliana and confirm estimates by qPCR. We further apply this approach to draft genomes deposited in NCBI and demonstrate accurate copy number estimation regardless of sequencing platform, with an overall median deviation of 14%. The expanded database of isolates with 16S copy number estimates increases the power of phylogenetic correction methods for determining organismal abundances from 16S amplicon surveys.
Tunable Valley Polarization and Valley Orbital Magnetic Moment Hall Effect in Honeycomb Systems with Broken Inversion Symmetry

Published: September 2015

AbstractIn this Letter, a tunable valley polarization is investigated for honeycomb systems with broken inversion symmetry such as transition-metal dichalcogenide MX2 (M = Mo, W; X = S, Se) monolayers through elliptical pumping. Compared to circular pumping, elliptical pumping is a more universal and effective method to create coherent valley polarization. When two valleys of MX2 monolayers are doped or polarized, a novel anomalous Hall effect (called valley orbital magnetic moment Hall effect) is predicted. Valley orbital magnetic moment Hall effect can generate an orbital magnetic moment current without the accompaniment of a charge current, which opens a new avenue for exploration of valleytronics and orbitronics. Valley orbital magnetic moment Hall effect is expected to overshadow spin Hall effect and is tunable under elliptical pumping.

Published: September 2015

AbstractHere we report the first demonstration for centro-apical self-organization of organic semiconductors in a line-printed organic semiconductor: polymer blend. Key feature of this work is that organic semiconductor molecules were vertically segregated on top of the polymer phase and simultaneously crystallized at the center of the printed line pattern after solvent evaporation without an additive process. The thickness and width of the centro-apically segregated organic semiconductor crystalline stripe in the printed blend pattern were controlled by varying the relative content of the organic semiconductors, printing speed and solution concentrations. The centro-apical self-organization of organic semiconductor molecules in a printed polymer blend may be attributed to the combination of an energetically favorable vertical phase-separation and hydrodynamic fluids inside the droplet during solvent evaporation. Finally, a centro-apically phase-separated bilayer structure of organic semiconductor: polymer blend was successfully demonstrated as a facile method to form the semiconductor and dielectric layer for OFETs in one- step.

AbstractCell-free protein synthesis is used to produce proteins with various structural traits. Recent bioinformatics analyses indicate that more than half of eukaryotic proteins possess long intrinsically disordered regions. However, no systematic study concerning the connection between intrinsic disorder and expression success of cell-free protein synthesis has been presented until now. To address this issue, we examined correlations of the experimentally observed cell-free protein expression yields with the contents of intrinsic disorder bioinformatically predicted in the expressed sequences. This analysis revealed strong relationships between intrinsic disorder and protein amenability to heterologous cell-free expression. On the one hand, elevated disorder content was associated with the increased ratio of soluble expression. On the other hand, overall propensity for detectable protein expression decreased with disorder content. We further demonstrated that these tendencies are rooted in some distinct features of intrinsically disordered regions, such as low hydrophobicity, elevated surface accessibility and high abundance of sequence motifs for proteolytic degradation, including sites of ubiquitination and PEST sequences. Our findings suggest that identification of intrinsically disordered regions in the expressed amino acid sequences can be of practical use for predicting expression success and optimizing cell-free protein synthesis.
What Patients with Addiction Disorders Need from Their Primary Care Physicians: A Qualitative Study

Published: September 2015

Background Although strong relationships between primary care providers (PCPs) and patients with addictive disease are essential for care, these relationships are often strained. Providers frequently have negative attitudes about treating these patients, in part due to the practical and psychosocial challenges that come with addictive disease. Resulting hostility frequently causes avoidance of primary care by patients with potentially increased morbidity. However, gaining knowledge of patient perspectives on these relationships could improve physician attitudes toward patients with addictive disease and relatedly improve care. Methods The authors conducted 18 semistructured interviews of patients with current or prior debilitating addictive disease recruited from a primary care practice in East Baltimore. Interview transcripts were analyzed using editing analysis to reveal major themes. Results Participants elucidated several provider characteristics that were essential for successful relationships. Providers needed to be knowledgeable about addiction, feel responsible for treating these patients, emphasize overall health, and engage patients in their own care. Additionally, participants strongly desired providers who treated them as “people” that they cared about. Interestingly, interviewees also frequently cited patient characteristics that could affect the strength of patient-provider relationships. These included being concerned about their health, feeling deserving of care, and having appropriate psychiatric care for concomitant mental health conditions. Practical obstacles and a disorganized mindset impeded patient-provider relationships. Conclusions The interpersonal dynamics of the patient-provider relationship are particularly important for patients with addictive disease, as this relationship may be one of the most stable and rewarding in their lives. Patients felt that greater understanding of the practical and psychosocial challenges of addiction enabled providers to more effectively address their health concerns and to be more caring and less judgmental. It is hoped that this work will contribute to providers’ understanding of patients with addictions, thus allowing them to form stronger relationships and ultimately provide better care.
Implicit measures of beliefs about sport ability in swimming and basketball
Authors: Mascret Nicolas , Falconetti Jean‐Louis , Cury François 
Published: September 2015

AbstractSport ability may be seen as relatively stable, genetically determined and not easily modified by practice, or as increasable with training, work and effort. Using the Implicit Association Test (IAT), the purpose of the present study is to examine whether the practice of a particular sport (swimming or basketball) can influence automatic beliefs about sport ability in these two sports. The IAT scores evidence that swimmers and basketball players automatically and implicitly associate their own sport with training rather than genetics, whereas non‐sportspersons have no significant automatic association. This result is strengthened when perceived competence and intrinsic motivation in swimming or basketball are high.
