Clinical Characteristics, Dynamic Profile of Radiology and Laboratory Findings in Coronavirus Disease 2019

Background Since December 2019, when coronavirus disease 2019 (Covid-19) emerged in Wuhan city and rapidly spread throughout China, more and more data from different area and different stages of disease have been needed.Methods In this retrospective, single-centre study, we included all 38 confirmed cases of Covid-19 in Weihai from Jan 24 to Feb 24, 2020. Patients were divided into group A by normal Oxygenation Index (OI), group B by abnormal OI (less than 400 mmHg). The dynamic changes in clinical laboratory parameters were tracked from day 1 to day 32 after the onset of the disease at 4-day intervals. Cases were analyzed for clinical, radiological features and laboratory data. Outcomes were followed up until Feb 24, 2020.Results 38 patients with Covid-19 were included in this study, 68.42% patients were family clustered, and 97.37% patients had a history of exposure. The mean days between exposure and onset were about 5 days. Most patients were men, mean age was 43 years, 52.6% patients had chronic diseases. Most patients had fever or cough, about a third of patients had expectoration or fatigue, and 5 (13.16%) patients had shortness of breath.
Full-length transcriptome sequencing of the identified fruit shape-related genes of the Olecranon honey peach

Background: The Olecranon honey peach shaped like an eagle’s beak. In this study, full-length transcriptome sequencing of the Olecranon honey peach and its bud mutant variant was performed by Oxford Nanopore Technologies to comparatively analyze the differentially expressed genes and the transcriptome to identify important fruit shape-related genes. Results: Full-length transcriptome sequencing was performed to analyze the two peaches. A consensus isoform was obtained and compared to the reference genome for an elimination of redundancy analysis. As a result, a final set of 58 596 transcript sequences was obtained. A total of 21 745 simple sequence repeats were obtained, and 18 322 alternative splicing (AS) events were identified. The comparative analysis of the non-redundant transcript revealed 2530 new gene loci and 37 364 novel transcripts. A total of 457 genes were differentially expressed in the two groups, including 169 up-regulated genes and 288 down-regulated genes. A total of 1519 transcripts were differentially expressed, of which 552 were up-regulated and 997 were down-regulated. Conclusions: In the case of the plant hormone signal transduction pathway identified by the KEGG annotation, our analyses revealed that differential expression of genes 9229 , 26004 , 22504 , 2822 , 2826 , 2824 , ONT.1953 , ONT.1950 , and ONT.1953 was related to the shape of the peach and may regulate the production of large fruit, via endogenous hormones, secondary metabolites, and signal transduction. This study provides useful information on the shape-related genes and transcripts in the Olecranon honey peach.
EFFECT OF SELENIUM ON SALT TOLERANCE IN MAIZE PLANTS

Two pot experiments during the seasons of 2017 and 2018 were conducted to investigate the effect of Se as Na2SeO4 (2.5 and 5 μM) as foliar applications on growth, photosynthetic pigments, Na/K homeostasis and eventually the yield of maize plants grown under three different levels of salinity (0, 50 and 100 mM NaCl). The results indicated that Se at 2.5 μM recorded the highest significant values in leaves and stem dry weights, total grain yield plant and grain filling as indicated by the weight of 100 kernels; As well as, Chl a, Chl b and K concentrations. On contrary, there was a significant decrease in Na concentration and Na/K ratio. Additionally, carotenoids did not reveal any significant changes between Se-treated plants and the untreated ones.
Elaboration of wide bandgap CIGS on silicon by electrodeposition of stacked metal precursors and sulfur annealing for tandem solar cell applications

A method was developed for the electrodeposition of Cu-In-Ga precursor layers to elaborate Cu(In,Ga)(S,Se)2 (CIGS) thin films on silicon substrates for future application as silicon/wide-gap CIGS tandem solar cells. An underlayer of Ag was first deposited on silicon substrates to ensure a good adhesion of the electrodeposited stack and to serve as cathode during the deposition process. Cu, In and Ga layers were then sequentially electrodeposited. Ag-Cu-In-Ga precursor layers were finally subjected to elemental sulfur annealing at 600 °C. Formation of compact and adherent AgCIGS is observed. X ray diffraction and photoluminescence analyses confirm the formation of wide-gap CIGS of about 1.6 eV, with a spontaneous gallium grading over the depth of the sample leading to the formation of a bi-layer structure with a gallium rich layer at the interface with silicon.
Peer-Led Team Learning (PLTL), Student Achievement and Engagement in Learning Chemistry

The main purpose of this study was to determine the effects of Peer-Led Team Learning (PLTL) strategy on the achievement and engagement level students in Chemistry. It was conducted at Casimiro A. Ynares Sr. Memorial National High School, Taytay, Rizal during the third quarter period of the school year 2018-2019. The participants of this study were chosen using purposive sampling. The sample students belong to one intact section of Grade 9 composed of 36 students. This study utilized a one-group pre-experimental research design. The results revealed that there is a significant difference in the chemistry achievement and engagement level of the students before and after their exposure to Peer-Led Team Learning. Significant difference was found in all the CIP engagement factors which are; cooperation, interest and participation after the students were exposed to PLTL. In overall there is a significant difference in the engagement mean of students before and after the implementation of PLTL. It was concluded that the use of Peer-Led Team Learning had positive effects to the learning achievement in chemistry and engagement of students. The workshop participants revealed they are felt comfortable learning under the peer leaders because they approachable and they were able to execute the lessons properly and clearly. The students also enjoyed sharing ideas and working with each other that triggered cooperation among them.
From the Andes to the Rocky Mountains: A Historical View of High-Altitude Pulmonary Hypertension

The current understanding of high-altitude pulmonary hypertension (HAPH) is largely attributable to the work of a small cadre of international scientists. The present article discusses the discovery and early investigations into HAPH that now serve as the foundation of our modern understanding of the disease. Further, though HAPH is clearly a distinct entity, we highlight how this early work led to a broader understanding of pulmonary vascular disease—including pulmonary arterial hypertension (PAH)—through the development of translational clinical models of disease, elucidation of hypoxic signaling, and therapeutics applicable to PAH.
Physical Educators’ Intention and Confidence in Teaching Students with Disabilities in Physical Education

The purpose of this study was to examine physical educators’ teaching behavior in inclusive physical education settings. Two different models were proposed a) Theory of Planned Behavior (TPB) predicted intention and teaching behavior and b) Teachers’ Professional Attributes predicted competence and teaching behavior in inclusive physical education. Participants were 125 Korean physical educators and completed the questionnaire. Multiple regression revealed that the Theory of Planned Behavior significantly predicted physical educators’ intention, F (3, 121) = 42.25, p< . 01. However, only intention had direct effect on educators’ teaching behavior. Teachers’ Professional Attributes predicted physical educators’ competence F (3, 106) = 17.67, p< . 01. Professional knowledge followed by competence had direct effects on teaching behavior. Finally, Teachers’ Professional Attributes accounted for 32.5% of the total variance in teaching behavior, relatively high in comparison in with the Theory of Planned Behavior which showed 22.8% of the total variance in teaching behavior.
Basic Word Extraction Algorithm Based on Morphological Rules for Balinese Texts

Stemming is the process of extracting the root word of an affixed word. The process is intended to reduce the variations in the word. In this research, we are interested in applying stemming on Balinese language. Previous works on stemming of the Balinese language applied rule-based method but only prefix and suffix were considered. Moreover, the rules were constructed without providing much attention to the morphology of the Balinese language. Rule-based method can be verified and validated with ease on simple problem but fail to do so on problems with high complexity such as Balinese language. To overcome the weaknesses of rule-based stemming on Balinese language, we propose a method that reduce all variations of affix on Balinese language by combining the rule- based approach and the Balinese language morphology. Based on experiments carried out, our proposed method obtained an average stemming accuracy of 99% which is better than 96.67% achieved by the previous method. Keywords: Stemming, Balinese language, Rule-based
Virtual Screening of DPP-4 Inhibitors Using QSAR-Based Artificial Intelligence and Molecular Docking of Hit Compounds to DPP-8 and DPP-9 Enzymes

Background: Dipeptidyl Peptidase-4 (DPP-4) inhibitors are becoming an essential drug in the treatment of type 2 diabetes mellitus, but some classes of these drugs have side effects such as joint pain that can become severe to pancreatitis. It is thought that these side effects appear related to their inhibition against enzymes DPP-8 and DPP-9. Objective: This study aims to find DPP-4 inhibitor hit compounds that are selective against the DPP-8 and DPP-9 enzymes. By building a virtual screening workflow using the Quantitative Structure-Activity Relationship (QSAR) method based on artificial intelligence (AI), millions of molecules from the database can be screened for the DPP-4 enzyme target with a faster time compared to other screening methods. Result: Five regression machine learning algorithms and four classification machine learning algorithms were used to build virtual screening workflows. The algorithm that qualifies for the regression QSAR model was Support Vector regression with R 2 pred 0.78, while the classification QSAR model was Random Forest with 92.21% accuracy. The virtual screening results of more than 10 million molecules from the database, obtained 2,716 hit compounds with pIC50 above 7.5. Molecular docking results of several potential hit compounds to the DPP-4, DPP-8 and DPP-9 enzymes, obtained CH0002 hit compound that has a high inhibitory potential against the DPP-4 enzyme and low inhibition of the DPP-8 and DPP-9 enzymes. Conclusion: This research was able to produce DPP-4 inhibitor hit compounds that are potential to DPP-4 and selective to DPP-8 and DPP-9 enzymes so that they can be further developed in the DPP-4 inhibitors discovery. The resulting virtual screening workflow can be applied to the discovery of hit compounds on other targets.
Academic writing MOOCs – a blended learning approach

The paper discusses a blended learning approach to teaching academic writing using an externally created MOOC fully incorporated into the existing pedagogic design. The authors intend to demonstrate potentials and limitations of mixed model learning in the ESP classroom. To this day there has been little research of repurposing MOOCs for language classes, as they are usually more practical and interactive. However, the authors believe that the online component of the blended course creates an additional dimension for language acquisition and allows to address numerous general issues on academic writing which are not traditionally discussed in ESP/EAP classes. Based on the results of the case study conducted at RUDN university, the study outlines numerous benefits of blended learning trajectory. However, the investigation revealed a few challenges, some of which can be easily remedied, whereas others are of more problematic nature.
Human Myeloid-­Derived Suppressor Cells in Solid Organ Transplantation

The balance between effector and regulatory immune cells needs a very exquisite balance in the context of solid organ transplantation to avoid the rejection of the organ while maintaining the more immune competence as possible. In the last two decades the role of regulatory immune cells has been extensively studied, mainly with regulatory T cells (Tregs), and in the last years another subset of regulatory cells, named myeloid derived suppressor cells (MDSC), has gained importance. These cells have different mechanisms of action and some of them are differentially regulated in a number of immune-mediated processes. Thus, MDSC, which play important roles in tolerance of experimental models of solid organ transplantation, have been proposed as biomarkers of the degree of immunosuppression and risk of rejection. Besides, they are also thought as therapeutic approach for the establishment of tolerance in human transplantation.
Sporoderm ultrastructure of Oedipodium griffithianum (Oedipodiopsida, Bryophyta)

Spores of Oedipodium griffithianum are studied under SEM and TEM, revealing a unique combination of characters: distinct trilete laesura, distal surface densely covered by club-shaped papillae often fused by their distal parts, perine mostly eroded and fallen off in the mature spores, and layer between exine and intine strongly variable in size and texture between distal and proximal hemisphere. This layer is homogeneous or occasionally totally absent at distal pole, lamellose in equatorial region in sections of fully developed spores, while indistinctly lamellose to homogeneous in a slightly premature spores; in the proximal hemisphere and in laesura it is thick and has complex structure. In somewhat premature spores an electron dense perine is observed upon exine, but it seems to easily fall off during spore maturation, so fully mature spores almost lack perine like in Bruchia brevifolia. Oedipodium is similar to Sphagnopsida in distinct laesura, unstable perine and complex multilaminate innermost layer of exine, a remnant of tripartite lamella.
Development of a Neuroscience Motifs-based Teacher Training Program for Pre-Service Teachers in Special Education in Israel

In the last two decades, there is an increasing interest in the connection between neuroscience and education. However, there is a gap between the declarative statements about the importance of implementation of neuroscience in education and the small number of suggested programs which actually present an implementation in practice. This study describes the development, design and the planning of implementation of a Neuroscience Teacher Based Teacher Training Program (NMTTP) for Pre-Service Teachers (PSTs) in special education track. In addition, this study presents the current literature addressing neuroeducation and curriculum, describes the gap in knowledge concerning it and focuses on the need for constructing a neuroeducational curriculum, specifically when dealing with learning disabilities. The structure of the neuroscience-based training program, its main topics and its originality are presented and discussed.
Thermochemical characteristics of dairy manure and its derived biochars from a fixed-bed pyrolysis

ABSTRACT Based on the data on the thermogravimetric analysis (TGA), oven-dried dairy manure was performed at moderate temperatures (673–1,073 K) with proper residence time of 60 min by a vertical fixed-bed pyrolyzer. The thermochemical properties of the dairy manure and its biochar products, such as elemental analysis and calorific value (higher heating value), were investigated to evaluate their potential use as biomass fuel. Furthermore, the true densities of the manure-derived biochars were also obtained to relate the property with their thermochemical properties. It showed that the calorific value of the dairy manure-derived biochar (denoted as DMBC) was on increasing trend with temperature, while its maximal increase occurred at around 873 K. This result was in high agreement with the data on the yields and carbon contents of DMBC products. By contrast, their contents of H, N, and O decreased slightly due to the devolatilization because of thermal decomposition reactions like depolymerization and carbonization. The optimal manure-derived biochar revealed an excellent characterization with high content of carbon (60 wt%) and calorific value (22.3 MJ/kg), low contents of nitrogen (0.5 wt%), and no traces of sulfur and heavy metals, suggesting that DMBC can be used as a solid fuel for energy use.
Drinking water from Chinese rivers: challenges of clarification

Despite an age-old preference in China to use spring or well water as drinking water, turbid waters from large rivers (Huanghe, Changjiang, Zhujiang, Hanjiang) have to be used for this purpose by the less privileged. Landslides and an increase in sediment loads in rivers are affected by population growth and deforestation. Clarification is required for shorter periods or throughout the year. Traditional clarifiers have been recorded since the 2nd century AD. Gelatinous and mucilaginous materials acting as adsorbents and coagulants of various efficiencies are identified and assessed. Some active substances are also known elsewhere. Certain materials contain toxic substances. Apricot kernels were later also used as a coagulant for turbid Nile water. Alum, also detected as a clarifier by humble Chinese, was chosen by engineers worldwide for use as a coagulant in waterworks. The need for clarified river water increases. Modern Chinese waterworks use aluminium polymers of their own production. Assistance is required for rural people in poor, remote counties without access to public water supplies. Primary school teachers could learn to monitor, in their communities, semi-quantitative clarification at the household level according to simplified water coagulation worked out for Moringa seeds.
Maternal knowledge and practices regarding childhood acute respiratory infections in Lubumbashi, DRC

Introduction Acute respiratory infections (ARIs) are a public health problem in the Democratic Republic of Congo (DRC) and cover a range of infections, from the common cold to pneumonia. ARIs are the leading cause of death in children under-5, with the majority of deaths occurring in developing countries. Objective To assess the knowledge and home-based practices used by mothers of children under-fives during episodes of ARI. Methods A cross-sectional study was carried out among mothers of children under-five who were selected in Lubumbashi (DRC). A pre-tested questionnaire administered by researchers was used for data collection. Results Of the 582 mothers interviewed, the majority had a good knowledge of the symptoms (87.46%), danger signs of severe ARIs (95.02%) and a good knowledge of the modes of transmission of ARIs (68.73%). Knowledge level was significantly associated with age and education level regarding modes of transmission. Three hundred and sixty-eight (63.23%) mothers indicated that they use traditional remedies: 252 (43.30%) apply palm oil to their children’s noses and as many mothers (n = 252; 43.30%) apply mentholatum ointment to the nose. Almost all of the mothers (n = 579; 99.48%) indicated that they dress the child with several layers of clothes. Oral self-medication was used by 575 mothers (98.80%). Conclusion The mothers’ knowledge of modes of transmission, symptoms and danger signs of ARIs was good in the community studied in Lubumbashi. Knowledge level was associated with age and level of education regarding modes of transmission.
On automorphisms of graded quasi-lie algebras

Let Z be the ring of integers and let K(Z,2n) denote the Eilenberg-MacLane space of type (Z,2n) for n ? 1. In this article, we prove that the graded group Am := Aut(? 2mn+1(? K(Z,2n))=torsions) of automorphisms of the graded quasi-Lie algebras ? 2mn+1(? K(Z,2n)) modulo torsions that preserve the Whitehead products is a finite group for m ? 2 and an infinite group for m ? 3, and that the group Aut(? *(K(Z,2n))=torsions) is non-abelian. We extend and apply those results to techniques in localization (or rationalization) theory.
Problems faced by the postgraduate scholars to access e-resources in Rajasthan

The present study aimed at identifying the constraints faced and suggestions as reported by the postgraduate scholars in the use of e-resources. In Rajasthan, out of five agricultural universities, three agriculture universities namely MPUAT (Udaipur), SKNAU (Jobner) and SKRAU (Bikaner) running postgraduate programmes for more than 20 yr were selected purposively. From each university, 60 respondents were selected randomly. The primary data were collected using questionnaire method and analysed using simple tabular analysis. The results revealed that the major constraints faced by the postgraduate scholars in use of e-resources were lack of trainings for e-resources, lack of professional & skilled persons in the library and lack of knowledge about information technology. As reported by the respondents to use e-resources the major suggestions were strengthening the library by employing the professional and technical staff by the university, training programmes must be organized for the students about use of e-resources and awareness generation by arranging different programmes for the users to educate them about e-resources. Hence, it was recommended that university should organize training programs for better use of e-resources. Besides, the facilities like improvement of internet speed, number of workstations with Wi-Fi facility and increasing the number of terminals and printers in the libraries, computer laboratories with access to internet should also be done.
