Phase equilibria in binary systems of individually non-mesomorphic components: propionates, isobutyrates, butyrates and valerates of cesium and barium at temperatures from 20 to 400 °C have been investigated by the me­thods of differential thermal analysis and polarization polythermal microscopy. In all systems, the formation of intermediate li­quid-crystalline solutions of smectic modification (type A) was established. The tempe­rature-concentration regions of the formation of ionic liquid crystals and glasses are determined. The studies carried out show that in binary systems of cesium and barium alkanoates interme­diate liquid-crystal solutions are generated due to the latent mesomorphism of the correspon­ding cesium alkanoate and due to the eutectic decrease in liquidus temperatures in the binary systems. The thermal stability of the induced mesophase in the case of systems of the consi­dered type is influenced by the following factors: the degree of ordering of the melt, which correlates with the length of the alkyl chain of the alkanoate anion, and a decrease in the temperatures of the liquidus line relative to the latent clearing temperature. The possible influence of compounds melting congruently or incongruently, formed in binary systems, should also be taken into account. Experimental data indicate the largest temperature-concentration range of the mesophase in the butyrate system, where there are the most favorable conditions for the implementation of intermediate li­quid crystal solutions. Such conditions are the lar­gest decrease in liquidus temperatures in a series of systems relative to the latent clearing point, as well as an additional increase in thermal stability due to the formation of a congruently melting compound of anisometric structure. In the case of the valerate system, a certain increase in anisotropy in comparison with the butyrate system is leveled by high liquidus temperatures; here is the narrowest region of existence of the intermediate mesophase due to its thermal destabilization.

Background: The association between fibroblast growth factor 21 (FGF21) and cardiovascular disease (CVD) risk remains unclear. We conducted this systematic review and meta-analysis to evaluate the association between FGF21 and CVDs, and relevant vascular parameters.Methods: PubMed and Web of Science databases were systematically searched to identify relevant studies published before March 2021. The FGF21 concentration was compared between individuals with and without CVDs. The effect of FGF21 on CVD risk was assessed by using hazard ratio (HR) and odds ratio (OR). The association between FGF21 and vascular parameters was assessed by Pearson's r. Study quality was assessed using Newcastle–Ottawa Scale and Joanna Briggs Institution Checklist.Results: A total of 29,156 individuals from 30 studies were included. Overall, the serum FGF21 concentration was significantly higher in CVD patients (p &lt; 0.001), especially for coronary artery disease (CAD) (p &lt; 0.001) and hypertension (p &lt; 0.001). The pooled OR (p = 0.009) and HR (p &lt; 0.001) showed that the risk of CVDs increased with FGF21. The linear association between FGF21 and vascular parameters, including pulse wave velocity (r = 0.32), carotid intima-media thickness (r = 0.21), ankle-brachial index (r = 0.33), systolic blood pressure (r = 0.13), and diastolic blood pressure (r = 0.05), was insignificant. The incidence of overall CVDs (p = 0.03) was significantly higher in individuals with higher FGF21 levels.Conclusion: High-level serum FGF21 concentration is closely associated with an increased risk of CVDs, which may be independent of vascular parameters. A standard FGF21 classification threshold needs to be established before clinical use for CVD risk assessment.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=241968, identifier: CRD42021241968.

Objective: We aimed to use SARS-CoV-2 antibody tests to assess the asymptomatic seroprevalence of individuals in high-risk hospital cohorts who's previous COVID-19 exposure is unknown; staff, and patients requiring haemodialysis or chemotherapy after the first wave.Methods: In a single Center, study participants had five SARS-CoV-2 antibody tests done simultaneously; one rapid diagnostic test (RDT) (Superbio Colloidal Gold IgM/IgG), and four laboratory tests (Roche Elecsys® Anti-SARS-CoV-2 IgG [RE], Abbott Architect i2000SR IgG [AAr], Abbott Alinity IgG [AAl], and Abbott Architect IgM CMIA). To determine seroprevalence, only positive test results on laboratory assay were considered true positives.Results: There were 157 participants, of whom 103 (65.6%) were female with a median age of 50 years (range 19–90). The IgG component of the RDT showed a high number of false positives (n = 18), was inferior to the laboratory assays (p &lt; 0.001 RDT vs. AAl/AAr, p &lt; 0.001 RDT vs. RE), and had reduced specificity (85.5% vs. AAl/AAr, 87.2% vs. RE). Sero-concordance was 97.5% between IgG laboratory assays (RE vs. AAl/AAr). Specificity of the IgM component of the RDT compared to Abbott IgM CMIA was 95.4%. Ten participants had positivity in at least one laboratory assay, seven (9.9%) of which were seen in HCWs. Two (4.1%) hematology/oncology (H/O) patients and a single (2.7%) haemodialysis (HD) were asymptomatically seropositive. Asymptomatic seroprevalence of HCWs compared to patients was not significant (p = 0.105).Conclusion: HCWs (9.9%) had higher, although non-significant asymptomatic seroprevalence of SARS-CoV-2 antibodies compared to high-risk patients (H/O 4.1%, HD 2.7%). An IgM/IgG rapid diagnostic test was inferior to laboratory assays. Sero-concordance of 97.5% was found between IgG laboratory assays, RE vs. AAl/AAr.

The toxicity and disposal concerns of organic solvents used in conventional extraction purposes has entailed the need for greener alternatives. Among such techniques, supercritical fluid extraction (SFE) has gained popularity by yielding extracts of high purity in a much faster manner. Carbon dioxide (CO2) is generally preferred as a supercritical solvent because of its lower temperature requirements, better diffusivity and easy removal. The present study describes the characterization of supercritical CO2 extracts of Indian variety of Cordyceps sinensis (CS)- a high-altitude medicinal mushroom widely revered in traditional medicine for its extensive anti-hypercholesterolemic, anti-inflammatory, anti-proliferative and energy-enhancing properties. Experimental parameters viz. 300 and 350 bar of extraction pressure, 60°C of temperature, 0.4°L/h CO2 of flow rate and use of 1% (v/v) of ethanol as entrainer were optimized to prepare three different extracts namely, CSF1, CSF2 and CSF3. High-performance thin-layer chromatography (HPTLC) was used for assessing the quality of all the extracts in terms of cordycepin, the pivot biomarker compound in CS. Characterization by HPTLC and GC-MS confirmed the presence of flavonoids and nucleobases and, volatile organic compounds (VOCs), respectively. The chromatographic data acquired from metabolite profiling were subjected to chemometric analysis in an open source R studio which illustrated interrelatedness between CSF1 and CSF2 in terms of two major principal components. i.e. Dim 1 and Dim 2 whose values were 40.33 and 30.52% in variables factor map plotted using the HPTLC-generated retardation factor values. The factor maps based on retention times of the VOCs exhibited a variance of Dim 1 = 43.95% and Dim 2 = 24.85%. Furthermore, the extracts demonstrated appreciable antibacterial activity against Escherichia coli and Salmonella typhi by generation of reactive oxygen species (ROS), protein leakage and efflux pump inhibition within bacterial pathogens. CSFs were elucidated to be significantly cytoprotective (p &lt; 0.05) in a simulated hypobaric hypoxia milieu (0.5% oxygen). CSF2 showed the best results by effectively improving the viability of human embryonic kidney (HEK 293) cells to 82.36 ± 1.76% at an optimum dose of 100 µg/ml. Levels of hypoxia inducible factor-1 alpha (HIF-1α) were modulated four-fold upon supplementation with CSF2. The results collectively evinced that the CSF extracts are substantially bioactive and could be effectively utilized as mycotherapeutics for multiple bioeffects.

Published: August 2021

Purpose: To explore the psychological problems (stress, depression, and anxiety) and the level of resilience among frontline healthcare workers (HCWs) who provide care for patients with coronavirus disease 2019 (COVID-19). Additionally, the current study identified the correlation among these problems, resilience, and demographics of participants. The study explored the main predictors of stress, depression, anxiety, and resilience.Methods: Both the descriptive cross-sectional correlational design and convenience sample technique were used to collect data from active Jordanian HCWs who directly deal with patients suspected or confirmed to be infected with COVID-19 and work at healthcare facilities in Jordan. Data were collected by using online questionnaires about the demographics, stress, anxiety, depression, and resilience of the participants.Results: Data were collected from 225 HCWs. Their mean age was 31.17 years (SD = 6.8). All the participants perceived different levels of stress, with most perceiving exposure to a high level of stress (distress) (46.2% with low level and 53.8% with high level of stress); approximately half of them (52.9%; n = 119) reported a high level of anxiety, and more than half (66.2%; n = 149) had a high level of depression. Additionally, an increased anxiety and depression level was significantly associated with the decreased resilience and increased stress level. Increased age and experience of HCWs are significantly correlated with increased stress levels. The participants having personal protection equipment (PPE) reduced anxiety and depression and increased resilience (p &gt; 0.05). The predictors of the main variables were varied in the study.Conclusion: Frontline HCWs involved in treating the patients with COVID-19 are liable to have a high level of stress that is associated with increased anxiety and depression levels. These high levels affect their mental well-being and resilience. Healthcare institutions in Jordan must tailor appropriate psychological interventions and support that are congruent with the needs of HCWs during and after caring for patients with COVID-19.
An Electronic Collaborative Learning Environment for Standardized Tests
Authors: Alyahya Sultan , Aldausari Asma 
Published: August 2021

The National Center for Measurement (Qiyas) was established for the purpose of conducting standardized tests in Saudi Arabia. The center has developed multiple Qiyas tests such as the General Aptitude Test (GAT) and the Scholastic Achievement Admission Test (SAAT). Qiyas tests are used as a pre-requisite requirement for applying to universities and to certain kinds of jobs in Saudi Arabia. Currently, students use traditional methods to prepare for these tests, e.g., studying from books and searching for available learning resources on the internet. These web-based resources are mostly static and only have general guidelines about the tests and a history of available test samples. This research proposes a computer-based collaborative learning (CL) environment that helps support learners during their preparation for the Qiyas tests. A four-stage approach is used in this research: (1) an intensive review of 30 CL platforms is carried out to investigate the available features, (2) two workshops are conducted to evaluate the appropriateness of the features identified in Stage 1 as well as to investigate what other features would be appropriate for Qiyas tests, (3) a CL platform is developed for Qiyas tests for a total of 21 features, (4) and, lastly, the platform is evaluated using two methods, in-depth interviews with experts and an empirical study with instructors and learners. The results show that the platform helps support learners in the participative, cognitive, interactive, and social dimensions of the learning processes. The results also help instructors promote the teaching experience.
Pathways to a Knowledge Society: A Proposal for a Hierarchical Model for Measuring Digital Literacy Among Israeli pre-service Teachers

Published: August 2021

This paper presents the results of an empirical study on validation of performance statements for an inventory of the digital literacy skills required for learning. These skills are used to determine digital readiness of pre-service teachers. The paper reports on validation of an adjusted set of 54 performance statements which were categorized into seven digital learning domains. The seven digital learning domains were validated based on structural equation modelling which was then confirmed by factor analysis using AMOS software. The results of the analysis indicate the existence of a multi-layered model where all digital learning domains are positively connected to each other. Our findings therefore suggest a strong statistical validity of the performance statement inventory. The findings also point to the fact that pre-service teachers are in a transit phase from digital immigrants to digital natives. That, in the context of Covid-19 pandemic, implies the need to invest in appropriate preparation and training of pre-service teachers to teach in an online environment. The inventory for measuring digital literacy can be used to assess teachers’ digital readiness on a regular basis, thereby enabling them to adjust the teaching materials and pedagogy to achieve the required level of digital readiness, as defined by the school.
