Crataegi folium have been used as medicinal and food materials worldwide due to its pharmacological activities. Although the leaves of Crataegus songorica (CS), Crataegus altaica (CA) and Crataegus kansuensis (CK) have rich resources in Xinjiang, China, they can not provide insights into edible and medicinal aspects. Few reports are available on the qualitative and quantitative analysis of flavonoids compounds of their leaves. Therefore, it is necessary to develop efficient methods to determine qualitative and quantitative flavonoids compounds in leaves of CS, CA and CK. In the study, 28 unique compounds were identified in CS versus CK by qualitative analysis. The validated quantitative method was employed to determine the content of eight flavonoids of the leaves of CS, CA and CK within 6 min. The total content of eight flavonoids was 7.8–15.1 mg/g, 0.1–9.1 mg/g and 4.8–10.7 mg/g in the leaves of CS, CA and CK respectively. Besides, the best harvesting periods of the three species were from 17th to 26th September for CS, from 30th September to 15th October for CA and CK. The validated and time-saving method was successfully implemented for the analysis of the content of eight flavonoids compounds in CS, CA and CK for the first time.

AbstractThe aim of this systematic review was to perform qualitative and quantitative analysis on the toxic effects of chloroquine (CQ) and hydroxychloroquine (HCQ) on skeletal muscles. We designed the study according to PRISMA guidelines. Studies for qualitative and quantitative analyses were selected according to the following inclusion criteria: English language; size of sample (> 5 patients), adult (> age of 18) patients, treated with CQ/HCQ for inflammatory diseases, and presenting and not presenting with toxic effects on skeletal muscles. We collected data published from 1990 to April 2020 using PubMed, Cochrane Library, EMBASE, and SciELO. Risk of bias for observational studies was assessed regarding the ROBIN-I scale. Studies with less than five patients (case reports) were selected for an additional qualitative analysis. We used the software Comprehensive Meta-Analysis at the confidence level of 0.05. We identified 23 studies for qualitative analysis (17 case-reports), and five studies were eligible for quantitative analysis. From case reports, 21 patients presented muscle weakness and confirmatory biopsy for CQ/HCQ induced myopathy. From observational studies, 37 patients out of 1,367 patients from five studies presented muscle weakness related to the use of CQ/HCQ, and 252 patients presented elevated levels of muscle enzymes (aldolase, creatine phosphokinase, and lactate dehydrogenase). Four studies presented data on 34 patients with confirmatory biopsy for drug-induced myopathy. No study presented randomized samples. The chronic use of CQ/HCQ may be a risk for drug-induced myopathy. There is substantiated need for proper randomized trials and controlled prospective studies needed to assess the clinical and subclinical stages of CQ/HCQ -induced muscle myopathy.

Retranslations of the Qur’an constitute an intriguing site of research with particular premises governing their production, dissemination and/or reception in Turkey. Its inherently religion-oriented context is accompanied by discussions on the sacred status of the source text, arguments on its untranslatability, translatorial human agency vis-à-vis the Holy creator, acknowledged Arabicity of the source text, etc. In this regard, each new translation of the Qur’an in Turkish is released with a motivation to justify its necessity amid abundant retranslations available in the target repertoire. Various approaches towards the conceptualization and instrumentalization of these Qur’anic translations create a meta-narrative on its own right. This study aims at exploring this particular discourse on the retranslations of the Qur’an with a bi-faceted study design composed of quantitative and qualitative analyses. The quantitative analysis focuses on the numeric changes of Qur’anic retranslations in respective decades, whereas the qualitative analysis concentrates on the statements of the translatorial agents on the motives behind their translational production. By shedding light on the discursive narrative postulated upon these retranslations, it is claimed that social, political, cultural and financial concerns have prevailingly governed the reproductions of this canonical work in Turkey. Keywords: Qur’an translation, religious-text translation, retranslation, discourse analysis.

The focus of the paper is on the frequency, distribution patterns and semantic profile of the necessitive impersonal reik(ė)ti ‘need’ in old and contemporary Lithuanian texts. The study employs corpus based quantitative and qualitative analysis to investigate the patterns of use of reik(ė)ti ‘need’ in the Database of Old Writings (16th-17th centuries) as well as the fiction sub-corpus of the Corpus of the Contemporary Lithuanian Language and the humanities and biomedical sciences sub-corpora of the Corpus of Academic Lithuanian (CorALit). The study follows van der Auwera and Plungian’s (1998) modality framework. The quantitative analysis shows that the present tense form reikia ‘need.PRS.3’ is the dominating one across all the sub-corpora analysed. The results of the qualitative study indicate that the deontic sub-type of participant external modality is prevailing in the old Lithuanian texts as well as in the fiction sub-corpus and in the biomedical sciences texts of the contemporary Lithuanian. The discourse of the humanities displays a fairly frequent employment of reik(ė)ti ‘need’ for discourse organising functions alongside the deontic uses. Although the usage patterns of reik(ė)ti ‘need’ in the biomedical sciences and the humanities share certain common features, they also point to discipline specific trends of argumentation. It is also important to observe that the objective deontic reik(ė)ti ‘need’ seems to gradually acquire the features of subjective deontic modality over time, which corresponds to the typical subjectification cline (cf. Traugott 1989).

The goal of this pre-study was to prescribe a solution to a perceived decrease in student engagement in an elective course on additive manufacturing. The objectives were to:identify in what activities the students are engaging; identify causes for lack of engagement in their studies, if any;identify possible changes to the additive manufacturing course.A mixed (quantitative and qualitative) triangulation interpretivist approach was used to address the first two objectives. Approximately half (1/2) the students stated that their studies was not their priority, two thirds (2/3) reported that they attended university primarily to earn a diploma rather than to learn and again two thirds (2/3) said that they had difficulty concentrating, signs that most students are not fully engaged in learning. The qualitative analysis provided insight and nuance to the quantitative analysis. It made it possible to identify sources for lack of engagement. Apart from the presence of electronic devices which distract attention, teaching methods, course content and evaluation modalities were often cited. Based on the findings, three changes are suggested to the course

The objective of this research were to know the factors that influence the students’ difficulties in retelling a movie. The subject of this research consists of 14 students at second semester STKIP Insan Madani Airmolek. The method used in this study was Descriptive Analysis Research. The data of this research was gathered through retelling a movie test and giving questionnaire. The techniques of data analysis used quantitative and qualitative analysis. The quantitative analysis was used to count the percentage of student’s score test and students answer the questionnaire. On the other hand, the qualitative analysis used to describe or interpret the result of quantitative analysis result. The researcher obtained the scores of the test result were 43, 57%. It was categorized less. And then the factors that influence students’ difficulties based on indicators of retelling a movie are English movie media, limited educational background to watch English movie and students’ less practice.The factors that influence difficulties from the internal factor was intelligence got 54%, interest got 78% and fatigue got 3%. The most factors that influence is interest. It got 78% of the students felt uninterested to watch the movie and retell it. The factors that influence difficulties from the external factors were family (56%), school (24%), society (57%). Society factors most influences the students’ difficulties in retelling a movie because the students have more interaction with it. The result of the research showed the factors that influence students’ difficulties occurred because of inappropriate media, students’ bad study habit, students’ point of view, laziness, and bad action negative activities inside and outside them.

This article examined the personal profiles of the Heads of Government of countries in South/North America and how they communicated with their audiences on institutional measures to contain COVID-19. Analyses were carried out on data collected from Twitter from November-2019 to November-2020. This study includes: i)quantitative analysis, measuring categories and emphases in the communication of tweets, retweets, likes, and comments on matters relevant to the pandemic; ii)qualitative analysis that allowed evaluating speeches to identify political interference and the effectiveness of communication at critical moments of the pandemic. It was possible to infer that each president has his singularities and understanding about Social Media’s use as a more direct communication tool with his audience. It was also found that successful communication is not directly proportional to the volume of messages on Twitter, but to socio-political aspects and institutional leadership that can make a difference in Social Media in combating COVID-19.
