The combined effect of 1‐methylcyclopropene and citral suppressed postharvest grey mould of tomato fruit by inhibiting the growth of Botrytis cinerea
Authors: Shenglong Du , Jihong Zhang , Shaoyang Chen , Shuang Ma , Li Zeng 
Published: December 2018

Abstract1‐Methylcyclopropene (1‐MCP, 1 μl/L) and 1 × minimum fungicidal concentration (MFC) citral alone and in combination were used to treat on postharvest tomato fruits to investigate their influence on disease incidence and postharvest quality during fruit storage, which were stored at 90%–95% relative humidity and 25 ± 2°C. Weight loss, pH, hue angle (Hue°), total soluble solid (TSS), ascorbic acid content, firmness and antioxidant enzyme activities were evaluated after each storage period. 1 μl/L 1‐MCP or 1 × MFC citral reduced weight loss, retarded peel colour changes and retained postharvest fruit quality. 1 μl/L 1‐MCP + 1 × MFC citral could better maintain firmness and ascorbic acid content and increase antioxidant enzyme activities, compared to other treatments. Disease incidence of tomato fruit was significantly decreased, and spore germination and mycelia growth of Botrytis cinerea were suppressed by the combined treatment with 1 μl/L 1‐MCP and 1 × MFC citral. These results indicate that the combined treatment could effectively delay postharvest tomato fruits senescence and inhibit postharvest pathogens in vitro.

Authors: Wei Wanrui , Niu Yunchao , Ge Xiaohua 
Published: December 2018

ABSTRACTBackgroundCore competencies of intensive care unit (ICU) nurses were defined as the essential capability to influence patient safety and interdisciplinary collaboration; however, there has been no research conducted that relates to core competencies of ICU nurses at Chinese tertiary‐A hospitals in Shanghai.Aims and objectivesTo investigate the current state of core competencies and the factors that influence this key capability in ICU nurses in Chinese tertiary‐A hospitals.DesignThis was a multicentre, cross‐sectional study.MethodsA convenient sampling method was used to investigate 451 ICU nurses at five tertiary‐A hospitals in Shanghai. Data were collected using self‐administered questionnaires.ResultsThe core competencies of ICU nurses were above average, and the scores of seven dimensions, ranked from first to last, were medical ethics, clinical practice, nurse–nurse co‐operation, assessment and decision‐making, personal and professional development, teaching and research and nurse–physician co‐operation. Multivariate linear regression analysis showed that the factors exerting an influence on the core competencies of ICU nurses were title, role incumbent and ICU department.ConclusionThis study showed an above‐average level of core competencies among ICU nurses in tertiary‐A hospitals in Shanghai; however, competencies related to nurse–physician co‐operation and the translation of research into practice were underdeveloped.Relevance to clinical practiceNursing managers should implement targeted interventions to improve nurse–physician co‐operation and translate research into practice competencies, such as high‐fidelity simulation, inter‐professional education, scientific research training and innovative skills tutorials. Moreover, this study demonstrated the influencing factors that can be used to improve core competences of ICU nurses.
Dynamical behavior of fractional‐order energy‐saving and emission‐reduction system and its discretization
Authors: Chen Zhijing , Liu Wenjun 
Published: December 2018

AbstractThis paper attempts to explore dynamical behavior and mathematical properties of the three‐dimensional fractional‐order energy‐saving and emission‐reduction system. Theoretically, the conditions of local stability of fractional‐order system's equilibrium points are obtained. Numerical investigations on the dynamics of this system are carried out, and the existence of the asymptotically stable attractor is found. Combined with the fractional‐order subsystem, we discuss the relationship between energy‐saving and emission‐reduction and economic growth, and carbon emissions and economic growth. Furthermore, we discretize the fractional‐order system and give necessary and sufficient conditions of its stabilization. It is shown that the stability of the discretization system is impacted by the system's fractional parameter. Numerical simulations show the richer dynamical behavior of the fractional‐order system and verify the theoretical results.Recommendations for Resource Managers

The impact of carbon emissions on economic growth is one of the main reasons for energy‐saving and emission‐reduction.
Control measures on people's low‐carbon life through government intervention are required to protect the natural environment.
New energy‐saving and emission‐reduction technologies should be implemented to achieve sustainable social and economic development.

Published: December 2018

AbstractBackgroundA left ventricular (LV) endocardial lead implant to achieve cardiac resynchronization therapy (CRT) is feasible when a conventional implant failed due to anatomical or technical issues or when the venous implant was performed but the patient did not respond to the therapy.MethodsData about the implantation procedure (age, sex, clinical characteristics, anticoagulant use, and previous devices), patient characteristics (indication, technique used, lead model, complications), and follow‐up (clinical and echocardiographic outcome, LV lead electrical measurements) were analyzed for all CRT systems implanted using LV endocardial lead, due to failed conventional implant or nonresponse, between April 2011 and November 2016.ResultsThirty‐five patients were implanted with an active fixation LV endocardial lead during the study period, without significant complications. There were no dislodgements or severe complications related to the implant procedure in the follow‐up period (36 ± 20 months) and a high percentage of patients responded to therapy, as assessed by several indicators.ConclusionsAn LV endocardial lead implant was feasible when the conventional technique had previously failed or was not effective. A high rate of response was achieved without any significant complications.
Discrete emotions linking abusive supervision to employee intention and behavior
Authors: Peng Ann Chunyan , M. Schaubroeck John , Chong Sinhui , Li Yuhui 
Published: December 2018

AbstractDrawing on appraisal theories of discrete emotions, we propose and test a model in which abusive supervision directed toward oneself and toward work unit peers (coworker abusive supervision) are interactively related to generalized feelings of shame, anger, and fear. These discrete emotions, in turn, tend to precipitate distinct responses that do not directly target the supervisor. We tested our hypotheses with a three‐wave, time‐lagged survey of 285 full‐time workers from 55 work units. Consistent with our theorizing, supervisory abuse was associated with stronger feelings of shame while at work when the abusive supervision reported by one's coworkers was lower (vs. higher), whereas abuse had a stronger association with anger when coworkers also perceived relatively high levels of abuse. The distinct action tendencies associated with shame and anger are related to employees engaging in less voice behavior and more interpersonal deviance, respectively, and fear is related to higher turnover intentions. We discuss the study's implications for theory development concerning abusive supervision.

Published: December 2018

AbstractObjective/DesignWell documented asthma disparities in Chicago pose a continual challenge for the Chicago Public Schools (CPS). Coordinated Healthcare for Complex Kids (CHECK) is a health care demonstration project funded by a Centers for Medicare and Medicaid Services Health Care Innovation Award. A collaborative partnership was formed between CHECK and CPS. With CHECK support, CPS administered a survey to 160 nurses to understand the asthma problems nurses perceived and interest in intervention.ResultsSeventy‐five per cent (n = 120) completed the survey. While asthma was the top diagnosis managed by 95%, 72% reported gaps in asthma understanding. Appropriate communication between school nurses and providers occurred 33% of the time; 18% believed they received sufficient support to follow‐up on deficient paperwork. The barriers mentioned were lack of medications (73%), time (67%), and communication with providers (61%). When asked their opinions on potential interventions, 78% of nurses supported web‐based applications, 66% community health workers (CHW), and 66% stock albuterol in schools.ConclusionsThe greatest barriers for CPS nurses with asthma management are time and communication. Potential interventions such as web‐based communication applications and CHW in schools were well received.
What Mechanisms Underlie Implicit Statistical Learning? Transitional Probabilities Versus Chunks in Language Learning
Authors: Perruchet Pierre 
Published: December 2018

AbstractIn a prior review, Perrruchet and Pacton (2006) noted that the literature on implicit learning and the more recent studies on statistical learning focused on the same phenomena, namely the domain‐general learning mechanisms acting in incidental, unsupervised learning situations. However, they also noted that implicit learning and statistical learning research favored different interpretations, focusing on the selection of chunks and the computation of transitional probabilities aimed at discovering chunk boundaries, respectively. This paper examines the state of the debate 12 years later. The link between contrasting theories and their historical roots has disappeared, but a number of studies were aimed at contrasting the predictions of these two approaches. Overall, these studies strongly question the still prevalent account based on the statistical computation of pairwise associations. Various chunk‐based models provide much better predictions in a number of experimental situations. However, these models rely on very different conceptual frameworks, as illustrated by a comparison between Bayesian models of word segmentation, PARSER, and a connectionist model (TRACX).

SummaryReactive oxygen species (ROS) produced by NADPH oxidases, called respiratory burst oxidase homologs (Rbohs), play crucial roles in development as well as biotic and abiotic stress responses in plants. Arabidopsis has 10 Rboh genes, AtRbohA to AtRbohJ. Five AtRbohs (AtRbohC, ‐D, ‐F, ‐H and ‐J) are synergistically activated by Ca2+‐binding and protein phosphorylation to produce ROS that play various roles in planta, although the activities of the other Rbohs remain unknown. With a heterologous expression system, we found a range of ROS‐producing activity among the AtRbohs with differences up to 100 times, indicating that the required amounts of ROS are different in each situation where AtRbohs act. To specify the functions of AtRbohs involved in cell growth, we focused on AtRbohC, ‐H and ‐J, which are involved in tip growth of root hairs or pollen tubes. Ectopic expression of the root hair factor AtRbohC/ROOT HAIR DEFECTIVE 2 (RHD2) in pollen tubes restored the atrbohH atrbohJ defects in tip growth of pollen tubes. However, expression of AtRbohH or ‐J in root hairs did not complement the tip growth defect in the atrbohC/rhd2 mutant. Our data indicate that Rbohs possess different ranges of enzymatic activity, and that some Rbohs have evolved to carry specific functions in cell growth.

AbstractObjectiveTo determine the influence of tissue preparation and long‐term storage methods on structural integrity and risk of bacterial contamination of equine amnion.Study designProspective experimental investigationSample populationAmniotic membranes from 8 healthy mares (n = 440 tested samples).MethodsSamples for baseline bacteriology and histology were taken after removal of debris. The remaining tissue was divided and processed with 0.05% chlorhexidine or 2% iodine/0.25% acetic acid. Processed amnion samples were assigned to 1 of 9 combinations of storage media (saline, chlorhexidine, acetic acid) and temperature (4 °C, −20 °C, −80 °C). Samples were submitted for quantitative bacteriology and histopathology at 1 week, 4 weeks, and 3, 6, 9, and 12 months.ResultsBaseline bacterial levels ranged from <200 to > 150 000 colony‐forming units (cfu)/mL. None of the potentially pathogenic bacteria in baseline samples were subsequently cultured throughout the study. Nonpathogenic bacteria (median 20 cfu/mL), most commonlyBacillussp, were cultured sporadically across storage conditions. Tissue architecture was minimally affected histologically by processing protocol, storage temperature, or storage duration.ConclusionThe 2 processing protocols tested here resulted in minimal bacterial contamination or loss of structural integrity of equine amnion stored for up to 12 months at 4 °C, −20 °C, or −80 °C.Clinical significanceAmnion collected during the foaling season may be stored for up to 12 months without significant bacterial contamination or structural alterations.
Regulation of cardiomyocyte maturation during critical perinatal window
Authors: Kannan Suraj , Kwon Chulan 
Published: December 2018

AbstractA primary limitation in the use of pluripotent stem cell‐derived cardiomyocytes (PSC‐CMs) for both patient health and scientific investigation is the failure of these cells to achieve full functional maturity. In vivo, cardiomyocytes undergo numerous adaptive structural, functional and metabolic changes during maturation. By contrast, PSC‐CMs fail to fully undergo these developmental processes, instead remaining arrested at an embryonic stage of maturation. There is thus a significant need to understand the biological processes underlying proper CM maturation in vivo. Here, we discuss what is known regarding the initiation and coordination of CM maturation. We postulate that there is a critical perinatal window, ranging from embryonic day 18.5 to postnatal day 14 in mice, in which the maturation process is exquisitely sensitive to perturbation. While the initiation mechanisms of this process are unknown, it is increasingly clear that maturation proceeds through interconnected regulatory circuits that feed into one another to coordinate concomitant structural, functional and metabolic CM maturation. We highlight PGC1α, SRF and the MEF2 family as transcription factors that may potentially mediate this cross‐talk. We lastly discuss several emerging technologies that will facilitate future studies into the mechanisms of CM maturation. Further study will not only produce a better understanding of its key processes, but provide practical insights into developing a robust strategy to produce mature PSC‐CMs.

Authors: Iturricastillo Aitor , Granados Cristina , Reina Raúl , Sarabia José Manuel , Romarate Ander , Yanci Javier 
Published: December 2018

Purpose: To analyze the relationship between mean propulsive velocity (MPV) of the bar and relative load (percentage of the 1-repetition maximum [%1RM]) in the bench-press (BP) exercise and to determine the relationship of power variables (ie, mean concentric power [MP], mean propulsive power [MPP], and peak power [PP]) in change-of-direction ability, linear sprint, and repeated-sprint ability. Methods: A total of 9 Spanish First Division wheelchair basketball players participated in the study. All participants performed an isoinertial BP test in free execution mode, a 505 change-of-direction ability test, linear sprint test (20 m), and repeated-sprint ability test. Results: A nearly perfect and inverse relationship was observed for the BP exercise between the %1RM and MPV (r = −.97, R2 = .945, P < .001). The maximum loads for MP, MPP, and PP were obtained between 48.1% and 59.4% of the 1RM. However, no significant correlations were observed between strength and wheelchair performance. Conclusions: Wheelchair basketball players with different functional impairments showed a nearly perfect and inverse relationship for the BP exercise between the %1RM and MPV; thus the MPV could be used to estimate the %1RM. This finding has important practical applications for velocity-based resistance training in that coaches would be able to prescribe and monitor training load. Conversely, the absence of association between BP performance and field tests might be due to other factors such as the wheelchair–user interface, trunk-muscle activity, or propulsion technique, apart from strength variables.

Published: December 2018

Purpose: To investigate the effects of repeated-sprint training in hypoxia vs in normoxia on world-level male rugby union players’ repeated-sprint ability (RSA) during an international competition period. Methods: A total of 19 players belonging to an international rugby union senior male national team performed 4 sessions of cycling repeated sprints (consisting of 3 × eight 10-s sprints with 20 s passive recovery) either in normobaric hypoxia (RSH, 3000 m; n = 10) or in normoxia (RSN, 300 m; n = 9) over a 2-wk period. Before and after the training intervention, RSA was evaluated using a cycling repeated-sprint test (6 × 10-s maximal sprint and 20-s passive recovery) performed in normoxia. Results: Significant interaction effects (all P < .05, ) between condition and time were found for RSA-related parameters. Compared with Pre, maximal power significantly improved at Post in RSH (12.84 [0.83] vs 13.63 [1.03] W·kg−1, P < .01, ) but not in RSN (13.17 [0.89] vs 13.00 [1.01] W·kg−1, P = .45, ). Mean power was also significantly enhanced from Pre to Post in RSH (11.15 [0.58] vs 11.86 [0.63] W·kg−1, P < .001, ), whereas it remained unchanged in RSN (11.54 [0.61] vs 11.75 [0.65] W·kg−1, P = .23, ). Conclusion: As few as 4 dedicated specific RSH sessions were beneficial to enhance repeated power production in world-level rugby union players. Although the improvement from RSA to game behavior remains unclear, this finding appears to be of practical relevance as only a short preparation window is available prior to international rugby union games.

Published: December 2018

Purpose: To determine the discriminators as variables to select the under-16 national-team players and to examine the influence of biological age on physical/technical parameters among young basketball players. Methods: Thirty-four under-15 male basketball players performed several anthropometrical (height, wingspan, body mass, and fingers length) and physical (jumping, sprinting, throwing, flexibility, change-of-direction speed, and aerobic fitness) tests during the under-15 male national-team training camp. Maturity offset, lower-limb asymmetry index, and power outputs for jumping and sprinting were also computed. In addition, game performance was taken into consideration using game-related statistics (assists, turnovers, steals, rebounds, blocks, and points) of 5 games of during the previous regional tournament (April 2016). Cluster analysis was used to analyze the between-maturation status (prepubertal, pubertal, and postpubertal) differences in physical parameters. Results: The postpubertals showed a significantly better performance in power outputs (jumping and sprinting), throwing abilities, and blocks, whereas prepubertal performed significantly better in aerobic fitness and assists. Receiver-operating-characteristic curve confirmed maturational status (area under the curve [AUC] = 0.804; P < .05) and training experience (AUC = 0.789; P < .05) as the most important attributes in predicting under-16 national-team selection. Players with more than 5.5 years of training experience and less than 1.4 y to the age at peak height velocity were most likely to be selected. Conclusion: Maturational status seems to be a key variable that increases the probability of selection for the Portuguese under-16 national team.

Published: December 2018

Purpose: To predict the session rating of perceived exertion (sRPE) in soccer and determine its main predictive indicators. Methods: A total of 70 external-load indicators (ELIs), internal-load indicators, individual characteristics, and supplementary variables were used to build a predictive model. Results: The analysis using gradient-boosting machines showed a mean absolute error of 0.67 (0.09) arbitrary units (AU) and a root-mean-square error of 0.93 (0.16) AU. ELIs were found to be the strongest predictors of the sRPE, accounting for 61.5% of the total normalized importance (NI), with total distance as the strongest predictor. The included internal-load indicators and individual characteristics accounted only for 1.0% and 4.5%, respectively, of the total NI. Predictive accuracy improved when including supplementary variables such as group-based sRPE predictions (10.5% of NI), individual deviation variables (5.8% of NI), and individual player markers (17.0% of NI). Conclusions: The results showed that the sRPE can be predicted quite accurately using only a relatively limited number of training observations. ELIs are the strongest predictors of the sRPE. However, it is useful to include a broad range of variables other than ELIs, because the accumulated importance of these variables accounts for a reasonable component of the total NI. Applications resulting from predictive modeling of the sRPE can help coaching staff plan, monitor, and evaluate both the external and internal training load.
