Published: July 2017

AbstractBACKGROUNDCitrus fruit flavor is an important attribute prioritized in variety improvement. The present study compared juice volatiles compositions from 13 selected citrus genotypes, including six mandarins (Citrus reticulata), three sour oranges (Citrus aurantium), one blood orange (Citrus sinensis), one lime (Citrus limonia), one Clementine (Citrus clementina) and one satsuma (Citrus unshiu).RESULTSLarge differences were observed with respect to volatile compositions among the citrus genotypes. ‘Goutou’ sour orange contained the greatest number of volatile compounds and the largest volatile production level. ‘Ponkan’ mandarin had the smallest number of volatiles and ‘Owari’ satsuma yielded the lowest volatile production level. ‘Goutou’ sour orange and ‘Moro’ blood orange were clearly distinguished from other citrus genotypes based on the analysis of volatile compositions, even though they were assigned into one single group with two other sour oranges by the molecular marker profiles.CONCLUSIONSThe clustering analysis based on the aroma volatile compositions was able to differentiate mandarin varieties and natural sub‐groups, and was also supported by the molecular marker study. The gas chromatography–mass spectrometry analysis of citrus juice aroma volatiles can be used as a tool to distinguish citrus genotypes and assist in the assessment of future citrus breeding programs. The aroma volatile profiles of the different citrus genotypes and inter‐relationships detected among volatile compounds and among citrus genotypes will provide fundamental information on the development of marker‐assisted selection in citrus breeding. © 2017 Society of Chemical Industry

AbstractBACKGROUNDThe naturally occurring polyphenol resveratrol has been acknowledged with many beneficial biological effects. The aim of this study was to evaluate the influence of dietary resveratrol supplementation on meat quality, muscle antioxidative capacity and mitochondrial biogenesis of broilers. One hundred and eighty 21‐day‐old male Cobb broilers were randomly assigned to two groups and fed on a 0 mg kg−1 or 400 mg kg−1 resveratrol‐supplemented diet for 21 days. Then, chickens were slaughtered and pectoralis major muscle (PM) samples were collected for analysis.RESULTSThe results showed that resveratrol not only tended to increase (P < 0.10) PM pH24h but also significantly decreased (P < 0.05) PM L*45min, pH decline, drip loss and lactate content. Meanwhile, PM total antioxidative capacity and catalase activity were significantly increased (P < 0.05) by resveratrol, while malondialdehyde content was decreased (P < 0.10). Moreover, resveratrol significantly increased (P < 0.05) PM peroxisome proliferator‐activated receptor γ coactivator 1α and nuclear respiratory factor 1 mRNA levels, along with increased (P < 0.05) citrate synthase activity.CONCLUSIONResveratrol can be used as a feed additive to improve meat quality of broilers, which may be associated with improved muscle antioxidative status and mitochondrial biogenesis. © 2017 Society of Chemical Industry
Landscape Connectivity in the Upper Mzimvubu River Catchment: An Assessment of Anthropogenic Influences on Sediment Connectivity
Authors: van der Waal Bennie , Rowntree Kate 
Published: July 2017

AbstractConnectivity has been altered in many landscapes world‐wide and impacts the routing of water and sediment. Diminished ecological infrastructure can result in a reduced ability to retain water and soil that will impede ecosystem health and sustainable use of land and water resources. In the northern Eastern Cape Province of South Africa, the headwaters of the Mzimvubu River, land use change and land degradation over the past 50–100 years has initiated increased sediment connectivity through features such as gullies and incised river channels. The water resources of this catchment are largely undeveloped, but future development will be threatened by high suspended sediment loads. The Vuvu catchment, a headwater tributary of the larger Mzimvubu River system, is used as a case study to assess how hillslope–channel and channel–valley fill sediment connectivity has changed over the past 100 years. From detailed mapping of gullies, roads and livestock tracks, it was concluded that downslope connectivity added 22% and across‐slope drainage 159% to the drainage network. As a result of increased drainage efficiency, the main channel was incised and straightened, in turn reducing channel–valley fill connectivity. A conceptual model of changes to sediment connectivity is presented with recommendations for future restoration. Copyright © 2017 John Wiley & Sons, Ltd.

Published: July 2017

Ferrocene‐based polymers have drawn much attention in the past decades due to their unique properties and promising applications. However, the synthesis of hyperbranched polymers is still a great challenge. Here, two ferrocene‐based hyperbranched polytriazoles with high molecular weights are facilely prepared by the click polymerization reactions of ferrocene‐containing diazides (1) and tris(4‐ethynylphenyl)amine (2) using Cu(PPh3)3Br as catalyst in dimethylformamide at 60 °C for 5 and 9 h in satisfactory yields of 54.0% and 52.3%. The resulting polytriazoles are soluble in common organic solvents and thermally stable, with 5% weight loss temperatures up to 307 °C. They can be used as precursors to produce nanostructured ceramics with good magnetizability by pyrolysis at elevated temperature.

Published: July 2017

AimTo evaluate the association between lower urinary tract symptoms (LUTS) and incidental falls and fear of falling.MethodsWe used data obtained from the 2011 Korean Community Health Survey (KCHS) conducted between August and October 2011 in South Korea. The survey was carried out to estimate patterns of disease prevalence and morbidity in men >40 years old. The trained interviewers performed face‐to‐face sociodemographic questionnaires using computer‐assisted personal interviewing (CAPI) software, the International Prostate Symptom Score (IPSS), the Quality of Life score (EQ‐5D), and a questionnaire about past falls and fear of falling.ResultsData from 67 457 men were collected and analyzed. The subjects who had previously experienced a fall had slightly higher scores for IPSS, severity of LUTS, voiding LUTS, and storage LUTS than subjects with no prior fall history. A multivariate model of the relationship between falls and LUTS severity indicated that the relationship between the IPSS components and fall history was significant (mild, moderate, severe: OR = 1.00, 2.53, 3.91, respectively, P < 0.0001). A multivariate model of fear of falling and LUTS also showed a significant relationship between severity, voiding, and storage symptoms (severe IPSS: OR = 2.411, 95%CI: 2.2‐2.642, P < 0.001; voiding symptoms: OR = 1.766, 95%CI: 1.681‐1.856, P < 0.001; storage symptoms: OR = 1.705, 95%CI: 1.625‐1.789, P < 0.001).ConclusionThis study emphasizes the relationship between LUTS and falling. Furthermore, increased LUTS severity led to a higher risk of incidental falls. A high correlation between fear of falling and LUTS was also observed in this study.
Beware of the origin of numbers: Standard scoring of the SF‐12 and SF‐36 summary measures distorts measurement and score interpretations

Published: July 2017

ABSTRACTThe 12‐item Short Form Health Survey (SF‐12) is a generic health rating scale developed to reproduce the Physical and Mental Component Summary scores (PCS and MCS, respectively) of a longer survey, the SF‐36. The standard PCS/MCS scoring algorithm has been criticized because its expected dimensionality often lacks empirical support, scoring is based on the assumption that physical and mental health are uncorrelated, and because scores on physical health items influence MCS scores, and vice versa. In this paper, we review the standard PCS/MCS scoring algorithm for the SF‐12 and consider alternative scoring procedures: the RAND‐12 Health Status Inventory (HSI) and raw sum scores. We corroborate that the SF‐12 reproduces SF‐36 scores but also inherits its problems. In simulations, good physical health scores reduce mental health scores, and vice versa. This may explain results of clinical studies in which, for example, poor physical health scores result in good MCS scores despite compromised mental health. When applied to empirical data from people with Parkinson's disease (PD) and stroke, standard SF‐12 scores suggest a weak correlation between physical and mental health (rs.16), whereas RAND‐12 HSI and raw sum scores show a much stronger correlation (rs.67–.68). Furthermore, standard PCS scores yield a different statistical conclusion regarding the association between physical health and age than do RAND‐12 HSI and raw sum scores. We recommend that the standard SF‐12 scoring algorithm be abandoned in favor of alternatives that provide more valid representations of physical and mental health, of which raw sum scores appear the simplest.

AbstractThe development of organometal halide perovskite solar cells has grown rapidly and the highest efficiency of the devices has recently surpassed 22%. Because these solar cells contain toxic lead, a sustainable strategy is required to prevent environmental pollution and avoid healthy hazard caused by possible lead outflow. Here, in situ recycling PbI2 from thermal decomposition CH3NH3PbI3 perovskite films for efficient perovskite solar cells was developed. The thermal behavior of CH3NH3PbI3 perovskite and its individual components were examined by thermogravimetric analysis. By optimizing the process of thermal decomposition CH3NH3PbI3 film, the complete conversion from CH3NH3PbI3 to pure PbI2 layer with a mesoporous scaffold was achieved. The mesoporous structure readily promotes the conversion efficiency of perovskite and consequently results in high‐performance device. A perovskite crystal growth mechanism on the mesoporous PbI2 structure was proposed. These results suggest that in situ recycled PbI2 scaffolds can be a new route in manipulating the morphology of the perovskite active layer, providing new possibilities for high performance. Meanwhile, the risk of lead outflow can be released, and the saving‐energy fabrication of efficient solar cells can be realized.

Published: July 2017

AbstractSinglet fission solar cells combined with silicon photovoltaics allow the construction of parallel tandem solar cells, which benefit from better usage of high‐energy photons. A key limiting factor for the performance of such a tandem configuration is the transparency of the singlet fission front cell. Here we show highly transparent singlet fission solar cells with a top contact of thin Ca:Ag blends. The optimized contact leads to 81% average solar cell transmittance in the near‐infrared while maintaining more than half the short‐circuit current density compared with an opaque device. We simulate the performance of the parallel tandem stack and assess the improvements needed to fully realize the potential of singlet fission in this device configuration.

Published: July 2017

AbstractDespite the use of art therapy in clinical practice, its appreciation and reported beneficial results, no instruments are available to measure specific effects of art therapy among patients with personality disorders cluster B/C in multidisciplinary treatment. In the present study, we described the development and psychometric evaluation of the Self‐expression and Emotion Regulation in Art Therapy Scale (SERATS). Structural validity (exploratory and confirmatory factor analysis), reliability, construct validity and sensitivity to change were examined using two independent databases (n = 335; n = 34) of patients diagnosed with personality disorders cluster B/C. This resulted in a nine‐item effect scale with a single factor with a high internal reliability and high test–retest reliability; it demonstrated discriminant validity and sensitivity to change. In conclusion, the SERATS is brief and content‐valid and offers objective and reliable information on self‐expression and emotion regulation in art therapy among patients with personality disorders cluster B/C. Although more research on construct validity is needed, the SERATS is a promising tool to be applied as an effect scale and as a monitoring tool during art therapy treatment. © 2017 The Authors Personality and Mental Health Published by John Wiley & Sons Ltd

Published: July 2017

AbstractObjectivesFamily conflict has several adverse impacts on caregivers. Thus, there is significant value in determining the prevalence and predictors of family conflict, which can enable the health care provider to intervene if family conflict arises during end‐of‐life care. Accordingly, we aimed to explore the prevalence and predictors of conflict among the families of patients with advanced cancer who died in palliative care units.MethodsThis study was a nationwide multicenter questionnaire survey of bereaved family members of cancer patients who died in Japanese palliative care units participating in evaluation of the quality of end‐of‐life care.ResultsWe sent out 764 questionnaires, and 529 questionnaires (69.2%) were returned. As 70 family members refused to participate and we could not identify the answers in one questionnaire, we analyzed a total of 458 responses. The average Outcome‐Family Conflict score was 13.5 ± 4.9 (maximum score: 39.5), and 42.2% of family members reported at least one family conflict during end‐of‐life care. Greater family conflict was significantly associated with younger family age, with family members asserting control over decision making for patient care and with communication constraints among family members, although absent family members “coming out of the woodwork” reduced family conflict.ConclusionsMany families of patients with advanced cancer experienced conflict during end‐of‐life care. Family members asserting control over decision making and communication constraints among family members after diagnosis of cancer can predict the occurrence of family conflict. Absent family members “coming out of the woodwork” might reduce family conflict in particular cultures.
New Gaugings and Non‐Geometry

Published: July 2017

AbstractWe discuss the possible realisation in string/M theory of the recently discovered family of four‐dimensional maximal gauged supergravities, and of an analogous family of seven‐dimensional half‐maximal gauged supergravities. We first prove a no‐go theorem that neither class of gaugings can be realised via a compactification that is locally described by ten‐ or eleven‐dimensional supergravity. In the language of Double Field Theory and its M theory analogue, this implies that the section condition must be violated. Introducing the minimal number of additional coordinates possible, we then show that the standard S3 and S7 compactifications of ten‐ and eleven‐dimensional supergravity admit a new class of section‐violating generalised frames with a generalised Lie derivative algebra that reproduces the embedding tensor of the and gaugings respectively. The physical meaning, if any, of these constructions is unclear. They highlight a number of the issues that arise when attempting to apply the formalism of Double Field Theory to non‐toroidal backgrounds. Using a naive brane charge quantisation to determine the periodicities of the additional coordinates restricts the gaugings to an infinite discrete set and excludes all the gaugings other than the standard one.

BackgroundBoth common and rare genetic variants may contribute to risk of developing prostate cancer. Genome‐wide association studies (GWASs) have identified ∼100 independent, common variants associated with prostate cancer risk. However, little is known about the association of rare variants (minor allele frequency [MAF] <1%) in the genome with prostate cancer risk.MethodsA two‐stage study was used to test the association of rare, deleterious coding variants, annotated using predictive algorithms, with prostate cancer risk in Chinese men. Predicted rare, deleterious coding variants in the Illumina HumanExome‐12 v1.1 beadchip were first evaluated in 1343 prostate cancer patients and 1008 controls. Significant variants were then validated in an additional 1816 prostate cancer patients and 1549 controls.ResultsIn the discovery stage, 14 predicted rare, deleterious coding variants were significantly associated with prostate cancer risk (P < 0.01). In the confirmation stage, Q1631H in TEX15 (rs142485241), a DNA repair gene, was significantly associated with prostate cancer risk (P = 0.0069). The estimated odds ratio (OR) of the variant in the combined analysis was 3.24 (95% Confidence Interval 1.85‐6.06), P = 8.81 × 10−5. Additionally, rs28756990 (V741F) at MLH3 (P = 0.06) and rs2961144 (I126V) at OR2A5 (P = 0.065) were marginally associated with prostate cancer risk in the replication stage.ConclusionsOur study provided preliminary evidence that the rare variant Q1631H in DNA repair gene TEX15 is associated with prostate cancer risk. This finding complements known common prostate cancer risk‐associated variants and suggests the possible role of DNA repair genes in prostate cancer development.

AbstractBACKGROUNDCarboxylesterases (CCEs) are one of three large detoxification enzyme families. Some CCEs are active on synthetic insecticides with ester structures. Anopheles sinensis is an important malaria vector in eastern Asia. This study identified and characterized the CCE genes in the A. sinensis genome and determined CCE genes associated with pyrethroid resistance using RNA sequencing (RNA‐seq) and quantitative reverse transcription − polymerase chain reaction (qRT‐PCR), in A. sinensis from Anhui, Chongqing, and Yunnan in China.RESULTSFifty‐seven putative CCEs were identified and placed into three classes, 12 subfamilies and 14 clades through phylogenetic and homology analyses. Exon sizes ranged from 31 to 4317 bp, with 49 CCEs having two to five exons and eight having six to 11 exons. A total of 183 introns were recognized with sizes ranging from 31 to 4317 bp. The 57 CCEs were located on 14 scaffolds, with 70% located on four scaffolds. The alpha‐esterase subfamily was significantly expanded compared with that of Anopheles gambiae. In a pyrethroid‐resistant strain, RNA‐seq detected five upregulated CCE genes and qRT‐PCR detected 12 upregulated CCE genes. The α‐esterase 10 (AsAe10) and acetylcholinesterase 1 (AsAce1) genes were the main CCE genes associated with pyrethroid resistance.CONCLUSIONThis information will be useful for further study of the CCE gene family and pyrethroid resistance mechanisms mediated by CCEs. © 2017 Society of Chemical Industry
Potential of migration of active compounds from protein‐based films with essential oils to a food and a food simulant

Published: July 2017

Migration tests at different temperatures and storage periods were performed to evaluate the release of active compounds from active whey protein films (WPFs) to a food and food simulants. Whey protein film incorporated with different levels of an optimized essential oils (EOs) blend (1%, 2%, 2.7%, and 5%, w/w) were prepared by casting. This blend contained EOs from rosemary and 2 species of cinnamon. Salami was packaged with WPF and stored during 180 days at 5°C. Temperature influenced significantly the migration of compounds (P<.1). It was observed that eucalyptol was the compound that presented the highest potential of migration into 95% ethanol (v/v). After contact of film with salami, it was observed that, in general, more than 50% of active compounds released from WPF to salami. It was observed that higher amounts of active compounds were released to salami than to fatty food simulant. Results suggested that the release of compounds depends on their affinity with the food/food simulant, temperature, their concentration in packaging, and composition of food. Active packaging may ensure the quality of food due the migration of compounds from EO with antimicrobial and antioxidant activity incorporated in the film to the foodstuff.
Nonparametric signed‐rank control charts with variable sampling intervals

Published: July 2017

AbstractVariable sampling interval (VSI) charts have been proposed in the literature for normal theory (parametric) control charts and are known to provide performance enhancements. In the VSI setting, the time between monitored samples is allowed to vary depending on what is observed in the current sample. Nonparametric (distribution‐free) control charts have recently come to play an important role in statistical process control and monitoring. In this paper a nonparametric Shewhart‐type VSI control chart is considered for detecting changes in a specified location parameter. The proposed chart is based on the Wilcoxon signed‐rank statistic and is called the VSI signed‐rank chart. The VSI signed‐rank chart is compared with an existing fixed sampling interval signed‐rank chart, the parametric VSI
‐chart, and the nonparametric VSI sign chart. Results show that the VSI signed‐rank chart often performs favourably and should be used.
