Published: October 2019

AbstractThe diallel cross constitutes an informative genetic design for choosing genitors and crosses in breeding programmes since it provides estimates of general (GCA) and specific (SCA) combining abilities. Because the breeding programme for Urochloa humidicola ([Rendle] Morrone & Zuloaga; syn. Brachiaria humidicola [Rendle] Schweick) at Embrapa Beef Cattle is recent, these estimates are still unknown. Thus, the aim of this study was to obtain the estimates of GCA and SCA from the partial diallel cross design between sexual and apomictic parents. The crosses involved nine sexual and ten apomictic parents. Seventy‐one full‐sib progenies were obtained and evaluated in an incomplete block design, using all parents and the cv. BRS Tupi as a check. The agronomic and forage quality traits were evaluated using seven harvests. Statistical analysis was performed using the mixed model approach. Significant variations were associated with GCA among sexual parents for biomass yield and forage quality traits. However, this cannot be observed for apomictic parents for GCA. The SCA effect was not significant for the assessed traits. These results showed the predominance of additive effects. Sexual parents SEX3 and SEX4 presented the highest potential for contributing favourable alleles in hybrid combinations. The absence of GCA among apomictic parents and SCA suggests the need to increase genetic variability for the generation of breeding populations of U. humidicola.
Applying theory to the black box: A model for empirically scoring biodata
Authors: Speer Andrew B. , Siver Sydney R. , Christiansen Neil D. 
Published: October 2019

AbstractDespite being an effective predictor of job performance, empirically keyed biodata assessments have been criticized as black box empiricism unlikely to generalize to new contexts. This paper introduces a model that challenges this perspective, explicating how biodata content, job demands, and criterion variables collectively influence the construct validity, and generalizability of empirically scored biodata. Across two field studies, expected changes in scale correlations with external measures were found that coincided with changes in the contextual similarity between calibration and holdout contexts, the criteria used, and the content validity of biodata items. Collectively, this paper offers a framework that helps understand and optimize empirical biodata keying in practice, furthering confidence for their use in applied settings.

Authors: Hyde Robin , MacVicar Sonya , Humphrey Tracy 
Published: October 2019

AbstractAimTo critically appraise and synthesise the current evidence related to the advanced practice nurse (APN) in the children and young people's healthcare setting.BackgroundA complex landscape of demand and change has influenced the healthcare delivery for children and young people. In the United Kingdom and internationally, governments have endorsed the need for workforce innovation with APN roles introduced to counter these challenges. However, little is known about the impact of these initiatives in the context of children and young people's health care.DesignSystematic review and narrative summary.Data sourcesCINAHL, MEDLINE, DARE, PubMed, Prospero and Cochrane Database of Systematic Reviews were searched for studies published in English language from July 1998 to 2018. Studies were selected based on key search terms and eligibility criteria.Review methodsThe selected studies were appraised using the Effective Public Health Practice Project for quantitative studies. An adapted version of the JBI data extraction tool for experimental/observational studies was used to extract the relevant key findings. This was conducted independently by two researchers.ResultsNine studies were included in the review. The review demonstrated roles were comparable in their clinical practice to medics yet offered higher levels of patient satisfaction, role modelling for staff and led practice initiatives to improve health literacy.ConclusionThis review demonstrates that APN roles in children and young people's health care provide clinical, organizational and professional benefits, with added value to organizations and patients, acting as role models and educators.ImpactThe findings from this review indicate further research is required to ascertain contextual issues that may influence the implementation of APNs. This research will impact APNs working with children and young people. Equally, it supports the evidence base for service commissioners outlining areas for future research.
Variation of QRS morphology of premature ventricular contractions originate from the left‐ventricular outflow tract during ablation
Authors: Qifang Liu , Ye Tian , Zhi Jiang , Jing Huang , Yidong Zhao , Long Yang 
Published: October 2019

AbstractIdiopathic ventricular arrhythmias originating from the aortic sinus of Valsalva often show preferential conduction to the right‐ventricular outflow tract, which may render radiofrequency ablation more difficult. We describe a patient with symptomatic premature ventricular contractions of left‐ventricular outflow tract origin presenting with a variation of QRS morphology during ablation. The correlation between the characteristics of local voltage potentials and the real origin site of the ventricular arrhythmia is discussed.
The future of fish‐based ecological assessment of European rivers: from traditional EU Water Framework Directive compliant methods to eDNA metabarcoding‐based approaches

Published: October 2019

AbstractMost of the present EU Water Framework Directive (WFD) compliant fish‐based assessment methods of European rivers are multi‐metric indices computed from traditional electrofishing (TEF) samples, but this method has known shortcomings, especially in large rivers. The probability of detecting rare species remains limited, which can alter the sensitivity of the indices. In recent years, environmental (e)DNA metabarcoding techniques have progressed sufficiently to allow applications in various ecological domains as well as eDNA‐based ecological assessment methods. A review of the 25 current WFD‐compliant methods for river fish shows that 81% of the metrics used in these methods are expressed in richness or relative abundance and thus compatible with eDNA samples. However, more than half of the member states' methods include at least one metric related to age or size structure and would have to adapt their current fish index if reliant solely on eDNA‐derived information. Most trait‐based metrics expressed in richness are higher when computed from eDNA than when computed from TEF samples. Comparable values are obtained only when the TEF sampling effort increases. Depending on the species trait considered, most trait‐based metrics expressed in relative abundance are significantly higher for eDNA than for TEF samples or vice versa due to over‐estimation of sub‐surface species or under‐estimation of benthic and rare species by TEF sampling, respectively. An existing predictive fish index, adapted to make it compatible with eDNA data, delivers an ecological assessment comparable with the current approved method for 22 of the 25 sites tested. Its associated uncertainty is lower than that of current fish indices. Recommendations for the development of future fish eDNA‐based indices and the associated eDNA water sampling strategy are discussed.
Pareuchiloglanis (Teleostei: Sisoridae) from the Pearl River, China with description of three new species
Authors: Dao Wei , Li Xu , Yang Hong‐Fu , Zhou Wei 
Published: October 2019

AbstractWe describe three new species of Pareuchiloglanis. Based on a comparison of 17 valid species of Pareuchiloglanis, the genus can be divided into two groups contingent on their gill opening size and the anus position. One group, which we call the large gill opening group, has a large gill opening extending to the base of the first pectoral‐fin element; the anus is obviously closer to pelvic‐fin insertion than the anal‐fin origin; this group includes five species distributed in the Red and Pearl Rivers, China. The other group has a small gill opening extending only to the middle base of the pectoral‐fin elements; the anus is usually located at the midpoint of the pelvic‐fin insertion to the anal‐fin origin or slightly behind. This group includes the other 12 species, which are distributed in the Mekong and Yangtze Rivers. The large‐gill‐opening group can be divided into two sub‐groups based on the length of the caudal peduncle. One sub‐group has a long caudal‐peduncle and the distance from the anal‐fin origin to caudal‐fin base is greater than distance from the pelvic‐fin insertion. This sub‐group is only distributed in the Pearl River drainage. Another sub‐group has a short caudal peduncle and the distance from the anal‐fin origin to the caudal‐fin base is typically smaller than the distance from the pelvic‐fin insertion. This sub‐group is only distributed in the Red River basin of China and Vietnam. The former will be called the large‐gill‐opening group with long caudal peduncle in the text and only includes one species P. longicauda. During our ongoing taxonomic work of specimens collected from Nanpan‐jiang and Beipan‐jiang (upper Pearl River drainage in Yunnan, China), some Pareuchiloglanis specimens that had the characters of the large‐gill‐opening group with long caudal peduncle represent three undescribed species.

AbstractIn this study, a quick‐freezing plate filled with low‐temperature phase‐change material (PCM) with a mass fraction of 15% was applied in household refrigerator. A single smooth quick‐freezing plate significantly reduced the amount of time required for food to pass through the maximum ice crystal generation zone, and this amount of time was 1/6 or 3/5 of that for the refrigerator in natural convection or air blast freezing. The rate of water loss using air blast freezing was 4.26% compared with that of the a single smooth quick‐freezing plate at only 1.60%. For various thicknesses of the experimental pork, the quick‐freezing effect of the double‐layer surface plate was better than those of the other conditions. For pork thickness of less than 6 mm, the quick‐freezing effect of the single smooth surface plate was better than that of air blast freezing.Practical ApplicationsIn this study, a new quick‐freezing plate with a phase‐change material (PCM) was developed specifically for a domestic refrigerator. The quick‐freezing effect can be equivalent to that of air blast freezing if food thickness does not exceed the specified range. The plate in this study consisted of an aluminum lid, a plastic shell, a cold‐storage agent, and a cold‐storage bag.

AbstractVernonia amygdalina is an herb commonly used in folk medicine; It possesses various compounds with therapeutic capabilities. Traditional extraction approaches applied to this plant may destroy its bioactive compounds and inherently contaminate them with toxic organic solvents. In this study, ultrasound‐assisted extraction combined with gas‐bubble flotation was applied to increase V. amygdalina extraction yield. The efficiency of water maceration was increased by 200%, without the drawbacks of the conventional extraction methods. The total phenolic content yield was 189 ± 12.7 (mg GAE/g dry weight) with a condensation efficiency of 115 ± 5.7%; and the total flavonoid content was 6.44 ± 1.68 (mg QE/g dry weight). Additionally, the antioxidant activity of the condensed foam was enhanced up to 120%. Analysis of the extract by FTIR revealed the presence of extractable chemical families: sesquiterpene lactones, saponins and flavonoids, and that the chemical characteristics of the extract were also preserved due to mild extracting conditions. Overall, this method is effective for extracting bioactive compounds from herbs with appealing advantages: no thermal degradation, organic solvent free extraction, and low energy consumption.Practical ApplicationsThe utilization of ultrasound‐assisted extraction and gas bubble flotation has been proven to be effective in condensing the aqueous extract of Vernonia amygdalina. Gas bubble flotation was shown to condense the herb extract by 120%, which is considered efficient given the simplicity and energy consumption of the process.

Published: October 2019

AbstractDiaphragmatic ectopic pregnancy is a rare status during the perinatal period. We reported that a 24‐year‐old woman with diaphragmatic ectopic pregnancy successfully received ultrasound‐guided percutaneous microwave ablation. It found that beta‐human chorionic gonadotropin level decreased showing 1067, 311.3 and 118.4 mIU/mL within five postoperative days, and P level reduced from 3.64 to 1.59 nmol/L. Contrast‐enhanced ultrasonography image on the third day after ablation indicated that there was no enhancement in the lesion. This case indicated that ultrasound‐guided percutaneous microwave ablation could be critical for a good outcome in diaphragmatic ectopic pregnancy.
The Emergence of Proto‐Institutions in the New Normal Business Landscape: Dialectic Institutional Work and the Dutch Drone Industry
Authors: Smolka Katrin M. , Heugens Pursey P. M. A. R. 
Published: October 2019

AbstractIn the current business landscape, in which technology‐enabled entrepreneurship is part of the New Normal, regulatory institutional structures are in constant flux. Previous studies have framed the challenges facing entrepreneurs in mature organizational fields as avoiding the power of overbearing regulators long enough to establish the legitimacy of their ventures. In fields typified by New Normal conditions, however, regulatory frameworks for evaluating new technology‐enabled ventures are often still lacking. Regulators may choose to actively reach out to entrepreneurs to arrive at a better understanding of the radical technological changes and high‐frequency entrepreneurial behavioural adaptations that occur in these settings. To grasp how novel regulatory institutional structures come about in the New Normal business landscape, we conducted a processual study of the emergence of a new technology that is the Dutch remotely piloted aircraft systems (drone) industry between 2000 and 2018. Our findings show that regulatory proto‐institutions result from dialectic institutional work in the form of structured interactions between entrepreneurs and regulators. Specifically, we present a process model that reveals how new regulatory structures evolve in contexts where high levels of technological and behavioural change induce systemic uncertainty, and enlarge the interdependence between entrepreneurs and regulators. We suggest that our process theory of proto‐institutional emergence generalizes towards other organizational fields in which technology‐enabled entrepreneurship has become the main driver of growth. Theoretically, our findings speak to the literatures on institutional work, proto‐institutional emergence, and the New Normal business landscape.
Accretion of differentiated achondritic and aqueously altered chondritic materials in the early solar system—Significance of an igneous fragment in the CM chondrite NWA 12651
Authors: Ebert Samuel , Patzek Markus , Lentfort Sarah , Bischoff Addi 
Published: October 2019

AbstractOne approach to decipher the dynamics of material transport and planetary accretion in the early solar system is to investigate xenolithic fragments in meteorites. In this work, we examined an igneous fragment from the NWA 12651 meteorite—the first igneous fragment found in any CM chondrite—by analyzing its mineralogy, rare earth elements (REEs), and O‐isotopes. The study shows that the exsolution lamellae of the igneous fragment consist of Fe‐rich and Ca‐rich pyroxene. Thus, the fragment was part of a progressive crystallization in a closed system, such as in a depleted magma reservoir or mantle. In this environment, the pyroxene co‐crystallized with plagioclase, resulting in a negative Eu anomaly and enrichment of the heavy REEs compared to the light REEs. The O‐isotopes of the fragment are more 16O‐enriched than the mafic minerals in the matrix or in other bulk CM chondrites; therefore, the fragment was formed in a different region than the NWA 12651 parent body. The iron meteorites Tucson and Deep Springs, the pallasite Milton, and the CB chondrites have similar O‐isotopes as the igneous fragment. However, no direct connection can be drawn and it is questionable if the fragment shares a same parent body with one of these meteorites. The close formation region to the CB chondrites may suggest a formation of the fragment in the carbonaceous chondrite region. Thus, a wide transport through the nebula of the early solar system may not have been necessary to move the fragment to the CM chondrite formation region.

SummaryThe cucurbit pathogenic bacterium Acidovorax citrulli requires a functional type III secretion system (T3SS) for pathogenicity. In this bacterium, as with Xanthomonas and Ralstonia spp., an AraC‐type transcriptional regulator, HrpX, regulates expression of genes encoding T3SS components and type III‐secreted effectors (T3Es). The annotation of a sequenced A. citrulli strain revealed 11 T3E genes. Assuming that this could be an underestimation, we aimed to uncover the T3E arsenal of the A. citrulli model strain, M6. Thorough sequence analysis revealed 51 M6 genes whose products are similar to known T3Es. Furthermore, we combined machine learning and transcriptomics to identify novel T3Es. The machine‐learning approach ranked all A. citrulli M6 genes according to their propensity to encode T3Es. RNA‐Seq revealed differential gene expression between wild‐type M6 and a mutant defective in HrpX: 159 and 28 genes showed significantly reduced and increased expression in the mutant relative to wild‐type M6, respectively. Data combined from these approaches led to the identification of seven novel T3E candidates that were further validated using a T3SS‐dependent translocation assay. These T3E genes encode hypothetical proteins that seem to be restricted to plant pathogenic Acidovorax species. Transient expression in Nicotiana benthamiana revealed that two of these T3Es localize to the cell nucleus and one interacts with the endoplasmic reticulum. This study places A. citrulli among the ‘richest’ bacterial pathogens in terms of T3E cargo. It also revealed novel T3Es that appear to be involved in the pathoadaptive evolution of plant pathogenic Acidovorax species.

Published: October 2019

AbstractSweet sorghum (Sorghum bicolor [L.] Moench) is a prospective bioethanol feedstock source. Four high‐biomass and sweet sorghum male lines and three grain sorghum female lines were intercrossed using Design II mating. Parents and hybrids were evaluated to (a) identify genetic sources to improve biofuel traits, and (b) determine the inheritance of biofuel and morpho‐agronomic traits. Total soluble sugars (TSS) per plant were determined using juice weight (JW) and Brix (°Bx). Plant height (PH), biomass (BM) and stalk diameter (SD) were also measured. Mean hybrid performance for PH, JW, TSS and BM was higher than the male parent means. Three male parents exhibited positive and significant general combining ability (GCA) for at least three traits. Among males, PI185672 showed the highest GCA for PH, °Bx and BM, while No. 08 exhibited the greatest GCA for JW and TSS. Most hybrids exhibited overdominance‐driven high‐parent heterosis for all traits except SD. Trait broad‐sense heritability ranged from 0.71 (BM) to 0.93 (PH). Results revealed that biofuel traits could be substantially improved through breeding, which will contribute to enhanced bioethanol production.

Published: October 2019

AbstractBackgroundRoughly, a fourth of all placental abruption cases have an acute aetiologic underpinning, but the causes of acute abruption are poorly understood. Studies indicate that symptoms of stress, depression, and anxiety during pregnancy may be associated with a higher risk of abruption.ObjectiveWe examined the rate of abruption in the 2 hours immediately following outbursts of anger.MethodsIn a multicentre case‐crossover study, we interviewed 663 women diagnosed with placental abruption admitted to one of the seven Peruvian hospitals between January 2013 and August 2015. We asked women about outbursts of anger before symptom onset and compared this with their usual frequency of anger during the week before abruption.ResultsThe rate of abruption was 2.83‐fold (95% confidence interval [CI] 1.85, 4.33) higher in the 2 hours following an outburst of anger compared with other times. The rate ratio (RR) was lower for women who completed technical school or university (RR 1.38, 95% CI 0.52, 3.69) compared to women with secondary school education or less (RR 3.73, 95% CI 2.32, 5.99, P‐homogeneity = .07). There was no evidence that the association between anger episodes and abruption varied by hypertensive disorders of pregnancy (ie preeclampsia/ eclampsia) or antepartum depressive symptoms.ConclusionThere was a higher rate of abruption in the 2 hours following outbursts of anger compared with other times, providing potential clues to the aetiologic mechanisms of abruption of acute onset.
