A multilevel analysis of factors affecting kindergartners’ creative dispositions in relations to child-level variables and teacher-level variables
Authors: Kang Eun Jin 
Published: September 2020

AbstractKindergarteners’ creative dispositions are not only affected by their individual characteristics, but also by the organizational creative climate of their kindergartens. Using the Hierarchical Linear Models (HLM), this study examined a correlation between a 5-year-old child’s variables (e.g. child’s creativity and their perceptions of creative classroom climate), teacher’s variables (e.g. the types of kindergarten, teacher’s perceptions of organizational creative climate, and teacher’s creative dispositions) and child’s creative dispositions. The study sample included a total number of 20 kindergarten teachers who teach 5-year-old children and a total number of 195 kindergarteners selected from 10 exemplary kindergartens (i.e. kindergartens recognized by the Ministry of Education in Korea for their outstanding curriculum) and 10 average kindergartens of similar size. The findings of the study are as follows. First, the levels of children’s creative thinking and their creative dispositions both were higher in the exemplary kindergartens than those in the average kindergartens. Furthermore, in terms of the levels of teachers’ creative dispositions and their perceptions of the organizational creative climate, teachers working in the exemplary kindergartens scored higher than those in the average kindergartens. Next, despite that no direct correlations existed between kindergarteners’ creative dispositions and teachers’ creative dispositions, kindergarteners’ creative dispositions were affected by the types of the kindergartens (e.g. the outstanding curriculum of the exemplary kindergartens) and teachers’ perceptions of organizational creative climate. In conclusion, this study indicates the significance of building an organizational creative climate of kindergartens not only for the children but for the teachers to foster children’s creative dispositions.

Abstract
Background
Social and cultural norms, operating through social networks, may influence an individual’s dietary choices. We examined correlations between social network characteristics and dietary patterns among South Asians in the United States (U.S.)

Methods
Data from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Social Network study were analyzed among 756 participants (mean age = 59 y standard deviation [SD] = 9 y; 44% women). A culturally adapted, validated food frequency questionnaire was used for dietary assessment. A posteriori dietary patterns using principal component analysis were named 1) animal protein, 2) fried snacks, sweets and high-fat dairy, and 3) fruits, vegetables, nuts and legumes. Social network characteristics were assessed using a standard egocentric approach, where participants (egos) self-reported data on perceived dietary habits of their network members. Partial correlations between social network characteristics and egos’ dietary patterns were examined.

Results
The mean social network size of egos was 4.2 (SD = 1.1), with high proportion of network members being family (72%), South Asian ethnicity (89%), and half having daily contact. Animal protein pattern scores were negatively correlated with fruits and cooked vegetables consumption of network. Fried snacks, sweets and high-fat dairy pattern scores were positively correlated with sugar-sweetened beverages, South Asian sweets, fried/fast foods and ghee (clarified butter) consumption of network. Fruits, vegetables, nuts and legumes pattern scores were positively correlated with vegetables, fruits, and brown rice/quinoa consumption of network.

Conclusions
Network member characteristics and their perceived dietary behaviors were correlated with dietary patterns of egos. Dietary intervention studies among South Asians should consider social network characteristics as candidate components for dietary intervention.
An Investigation into the Relationship Between Heart Rate Recovery in Small-Sided Games and Endurance Performance in Male, Semi-professional Soccer Players
Authors: Reinhardt Lars , Schulze Stephan , Kurz Eduard , Schwesig René 
Published: September 2020

Abstract
Background
The ability to recover in the shortest possible time plays an important role especially in intermittent sports such as soccer. Evidence suggests that a well-developed endurance performance has positive effects on the repeated-sprint ability and thus also on the short-term recovery. However, it has not been clarified whether these relationships still exist in a soccer-specific situation. Therefore, the purpose of this investigation was to evaluate the ability of semi-professional soccer players to recover during standardized small-sided games (SSGs) as an endurance performance indicator.

Methods
Eighteen male semi-professional soccer players (age, 23.5 ± 3.7 years) performed an incremental treadmill test (ITT) to determine their running velocity and heart rate at a fixed lactate threshold of 4 mmol L−1 (v4). Two days later, the players carried out six bouts of 4 vs. 4 SSGs (duration, 90 s; load to rest ratio, 1:1). A GPS-based tracking system was used to determine distances covered at four fixed speed zones (i.e., < 7.2 km/h, 7.2–14.4 km/h, 14.4–19.8 km/h, > 19.8 km/h) and total distance covered during the SSGs. Furthermore, the frequency of occurrence of accelerations (> 1.54 m s−2) was calculated. SSGs’ internal load was quantified by average heart rate and blood lactate concentration after the SSGs. Their recovery ability was evaluated using heart rate recovery (HRR) after the last bout of the SSGs.

Results
A very large correlation (r = − .91) with an explained variance of 84% was found between HRR and v4. Further, a better performance in the ITT was also related with a higher number of accelerations executed during SSGs (r = .60). The total distance and distances in predefined speed zones did not show any association to v4.

Conclusions
This study showed a strong relationship between HRR after standardized 4 vs. 4 SSGs and the soccer players’ endurance performance in a laboratory setting. Thus, besides being associated with endurance capacity, v4 seems sufficient to evaluate the sport-specific ability to recover in soccer players.
The impact of colors on human memory in learning English collocations: evidence from south Asian tertiary ESL students
Authors: Khan Jahangeer , Liu Chengyu 
Published: September 2020

AbstractThis paper aims to highlight the significance of color that captivates human attention in learning English collocations in an educational setting. In order to expedite the impact of color on memory, an empirical research was conducted, in which 30 South Asian ESL students of a local university in China were selected as participants, equally divided into the experimental and the control groups. All the participants were taught literal and context-based meanings of 30 English collocations for three consecutive days. A pre-test and a post-test were administered to assess the impact of color on the students’ working memory in learning English collocations. Prior to assessing the impact of color on memory, the participants in the experimental group were exposed to the underlined collocations as written on colorful papers (yellow), while same collocations were imprinted on simple white color papers for the controlled group. A t-test was administered for the statistical analysis of the data. Comparatively, in the post-test, the participants in the experimental group remarkably outperformed while retrieving English collocations and their meanings by the virtue of yellow color. The finding of the current paper lends support to the notion that color, as an environmental stimulus, may greatly affect human working memory in learning English collocations. The study is expected to provide implications to text and curriculum designers by supplementing ESL learners with colorful texts and images in order to harness their language efficiencies and performances.
#CardioOncology: Twitter chat as a mechanism for increasing awareness of heart health for cancer patients
Authors: Conley Claire C. , Goyal Neha G. , Brown Sherry-Ann 
Published: September 2020

AbstractConsideration of heart health for cancer survivors is increasingly important, as improved cancer survivorship has resulted in a growing number of survivors affected by cardiovascular disease. However, there is limited knowledge of cardio-oncology among both patients and a variety of health professionals. Thus, efforts are needed to increase awareness about cardio-oncology. Social media represents one potential opportunity to disseminate information about cardio-oncology to a large audience. We highlight one example of a social media educational/advocacy campaign conducted on Twitter (a “Twitter Chat”) that garnered nearly 1.2 million impressions (views by Twitter users) in just 24 h. We provide both quantitative and qualitative data to support the efficacy of using Twitter for such educational/advocacy campaigns, and describe key features that contributed to its success. Twitter Chats inexpensively utilize innovative technology to provide education and foster community. Long-term studies are needed to understand whether Twitter Chats can change knowledge and behavior related to cardio-oncology.

AbstractPatients with rheumatoid arthritis (RA) represent one of the fragile patient groups that might be susceptible to the critical form of the coronavirus disease − 19 (COVID-19). On the other side, RA patients have been found not to have an increased risk of COVID-19 infection. Moreover, some of the Disease-Modifying Anti-Rheumatic Drugs (DMARDS) commonly used to treat rheumatic diseases like Hydroxychloroquine (HCQ) were proposed as a potential therapy for COVID-19 with a lack of full understanding of their molecular mechanisms. This highlights the need for the discovery of common pathways that may link both diseases at the molecular side. In this research, we used the in silico approach to investigate the transcriptomic profile of RA synovium to identify shared molecular pathways with that of severe acute respiratory syndrome-corona virus-2 (SARS-COV-2) infected lung tissue. Our results showed upregulation of chemotactic factors, including CCL4, CCL8, and CCL11, that all shared CCR5 as their receptor, as a common derangement observed in both diseases; RA and COVID-19. Moreover, our results also highlighted a possible mechanism through which HCQ, which can be used as a monotherapy in mild RA or as one of the triple-DMARDs therapy (tDMARDs; methotrexate, sulphasalazine, and HCQ), might interfere with the COVID-19 infection. This might be achieved through the ability of HCQ to upregulate specific immune cell populations like activated natural killer (NK) cells, which were found to be significantly reduced in COVID-19 infection. In addition to its ability to block CCR5 rich immune cell recruitment that also was upregulated in the SARS-COV-2 infected lungs. This might explain some of the reports that showed beneficial effects.
Enhancing the roles of information and communication technologies in doctoral research processes
Authors: Stein Sarah J. , Sim Kwong Nui 
Published: September 2020

AbstractWhile information and communication technologies (ICT) are prominent in educational practices at most levels of formal learning, there is relatively little known about the skills and understandings that underlie their effective and efficient use in research higher degree settings. This project aimed to identify doctoral supervisors’ and students’ perceptions of their roles in using ICT. Data were gathered through participative drawing and individual discussion sessions. Participants included 11 students and two supervisors from two New Zealand universities. Focus of the thematic analysis was on the views expressed by students about their ideas, practices and beliefs, in relation to their drawings. The major finding was that individuals hold assumptions and expectations about ICT and their use; they make judgements and take action based on those expectations and assumptions. Knowing about ICT and knowing about research processes separately form only part of the work of doctoral study. Just as supervision cannot be considered independently of the research project and the student involved, ICT skills and the use of ICT cannot be considered in the absence of the people and the project. What is more important in terms of facilitating the doctoral research process is students getting their “flow” right. This indicates a need to provide explicit support to enable students to embed ICT within their own research processes.

AbstractBackgroundThe Y chromosome polymorphism has been widely studied for human migrations, population genetics, forensic applications, and paternity analysis. However, studies regarding genetic lineage and population genetic structure of the Y chromosome in different regions of Saudi Arabia are limited.AimThis study aimed to analyze the distribution of Y chromosome haplotypes in a sample of 125 native Saudi males from different geographic regions of Saudi Arabia and compare to previously published Y chromosome haplotype data from Saudi Arabia and some neighboring Arab populations.Materials and methodsBuccal swabs were collected from 125 healthy unrelated native Saudi males from different geographic regions of Saudi Arabia. Genomic DNA was extracted by Chelex®100; 17 Y-STR loci were amplified using the AmpFℓlSTR Yfiler PCR amplification kit and detected on the 3130 Genetic AnalyzerTM. Allele frequency and gene diversity were calculated with online tool STRAF. The Saudi population data were compared with the neighboring populations using pairwise genetic distances and associated probability values were calculated using the Y Chromosome Haplotype Reference Database Website (YHRD) software.Results and conclusionOne hundred six YSTR haplotypes and 102 YSTR alleles (excluding 4 null alleles) were identified having a discrimination capacity (DC) of 85.8%. The highest haplotype diversity (HD) and gene diversity (GD) were observed at the loci DYS 458 (0.817) and DYS385b (0.807), respectively. According to our results, the Iraqi and Qena (Egypt) populations appeared to have closer relatedness to the Saudi population as compared with Yemen. The UAE and Kuwait populations showed the same degree of relatedness to the Saudi population followed by Bahrain. On the contrary, the Adnanit and Qahtanit populations of Jordan demonstrated low genetic distance from the Saudi population. In short, studying a population sample of pure Saudi ethnicity enabled us to identify a unique set of haplotypes which may help in establishing genetic relatedness between Saudi and the neighboring Arab populations. The present paper, therefore, highlights the importance of ensuring ethnic originality of the study sample while conducting population genetics studies.

Published: September 2020

Abstract
Background
Bacterial wilt caused by Ralstonia solanacearum is one of the most devastating diseases in tomato cultivation. This study aimed to evaluate the effect of Bacillus and Trichoderma isolates to manage the bacterial wilt disease.

Main body of the abstract
Field experiments were conducted in a randomized complete block design at Mwea and Kabete sites in Kenya. The treatments included 3 Trichoderma; 2 Bacillus isolates; a mixture of T1, T2, and T4; chemical standard; and distilled water as control. Trichoderma and Bacillus isolates were grown on sterilized sorghum grain and cow manure carriers respectively. Antagonist’s inoculation was carried out by dipping tomato plants for 30 min in each treatment suspension. Each treatment was then applied at a rate of 150 ml/plant hole and this was repeated after 35 days. All the treatments significantly reduced bacterial wilt incidence and severity at P ≤ 0.05 than the control at both sites. Trichoderma isolate T1, followed by Bacillus isolate CB64, was the best in reducing the disease incidence by more than 61.66 and 53%, respectively at both sites. Treatment CB64 and T1 had the highest reduction of R. solanacearum population in the soil by 93.17 and 92.07%, respectively. However, control had a pathogen increase of 20.40%. CB64 and T1 performed significantly better compared to the standard, while the mixture of isolates T1, T2, and T4 performed the poorest in all parameters. The treatments also increased the yield of tomato.

Short conclusion
Results from this study showed that Trichoderma and Bacillus isolates are effective biological control agents for use in management of bacterial wilt.

Published: September 2020

Abstract
Background
Attempts based on increasing the efficacy of Baculovirus and/or reducing the application concentration of synthetic insecticides through integrated lepidopteran management are appreciated role for conserving the environment. Impact of the multiple nucleopolyhedrosis virus (SpliMNPV) with emamectin benzoate (Em) against the cotton leaf worm, Spodoptera littoralis, was examined to identify the effective strategy for applying both agents in the control program successfully.

Main body
The LC50 and LC90 were drastically decreased from 1.9 × 106 and 1.0 × 1010 PIB/ml in SpliMNPV treatment to reach 8.87 × 101 and 1 × 104 PIB/ml, respectively in the SpliMNPV concentrations + Em LC25 treatment. This interaction was considered as potentiation. Larvicidal activity of Em was highly increased by Em concentrations + SpliMNPV LC25 treatment than the separately Em treatment; however, this interaction was considered as additive. Moreover, the mixture treatment (SpliMNPV LC99 + Em LC50) provided almost full protection of viral pathogenicity up to 48 h at natural exposure periods. Furthermore, the mixture treatment had a negative impact on the insect survival and reproduction of treated individuals.

Conclusion
Results indicated that the virus infectivity was increased by a mixture treatment of SpliMNPV + Em in particular facing UV sunlight, which causes virus degradation as well as reduced the effective doses of Em. These findings suggest that this simultaneous treatment maybe an effective technique to be applied in S. littoralis control strategy.
Hyperbaric oxygen therapy after acute ischemic stroke with large penumbra: a case report

Published: September 2020

Abstract
Background
Hyperbaric oxygen therapy (HBOT) for the treatment of acute stroke has been under the radar for a long time. Previous studies have not been able to prove efficacy. Several factors might have contributed to such inconsistent results. The timing of delivering the hyperbaric oxygen in relation to the stage of stroke evolution may be an important factor. This was not taken into account in the previous studies as there was no feasible and standardized method to assess the penumbra in the acute phase. Now with the perfusion scan appearing as a key player in the acute stroke management, precise stroke patient selection for hyperbaric oxygen therapy deserves a second chance similar to mechanical thrombectomy.

Case presentation
A 62-year-old female patient who presented with acute large vessel stroke was not eligible for chemical or mechanical thrombectomy. There was a large penumbra on imaging. She got treated with several sessions of hyperbaric oxygen over a 2-week period immediately after stroke. The patient showed significant improvement on the follow-up perfusion imaging as well as some clinical improvement. The more impressive radiological improvement was probably due to the presence of relatively large core infarction at baseline affecting functional brain areas. The patient continued to improve clinically on her 6-month follow up visit.

Conclusion
Our case demonstrates immediate stroke-related penumbra improvement associated with HBOT. Based on that, we anticipate a potential role for HBOT in acute stroke management considering precise patient selection. Future randomized controlled trials are needed and should take that in consideration.

Published: September 2020

Abstract
Background
Emergency carotid artery stenting (CAS) is a frequent endovascular procedure, especially in combination with intracranial thrombectomy. Balloon guide catheters are frequently used in these procedures. Our aim was to determine if mechanical aspiration through the working lumen of a balloon occlusion catheter during the steps of a carotid stenting procedure achieve flow rates that may lead to internal carotid artery (ICA) flow reversal which consecutively may prevent distal embolism.

Methods
Aspiration experiments were conducted using a commercially available aspiration pump. Aspiration flow rates/min with 6 different types of carotid stents inserted into a balloon guide catheter were measured. Measurements were repeated three times with increasing pressure in the phantom. To determine if the achieved aspiration flow rates were similar to physiologic values, flow rates in the ICA and external carotid artery (ECA) in 10 healthy volunteers were measured using 4D-flow MRI.

Results
Aspiration flow rates ranged from 25 to 82 mL/min depending on the stent model. The pressure in the phantom had a significant influence on the aspiration volume. Mean blood flow volumes in volunteers were 210 mL/min in the ICA and 101 mL/min in the ECA.

Conclusions
Based on the results of this study, flow reversal in the ICA during common carotid artery occlusion is most likely achieved with the smallest diameter stent sheath and the stent model with the shortest outer stent sheath maximum diameter. This implies that embolic protection during emergency CAS through aspiration is most effective with these models.
