Authors: IŞIK Aynur , GÜNER Güneş , ZEYNELOĞLU Can , DEMİRKOL CANLI Seçil , TASTAN Hakki , AKYOL Aytekin
Published: August 2023

Background: Claudin 18.2 (CLDN18.2) is a tight junction protein expressed especially in gastric adenocarcinomas. The prognostic and clinicopathologic implications of CLDN18.2 expression is currently unknown. Zolbetuximab monoclonal antibody against CLDN18.2 is under investigation as a potential treatment for advanced gastric cancer (GC). We aimed to investigate the impact of CLDN18.2 expression in GC on prognosis and tumor features in a large Turkish cohort.

Methods: Seven tissue microarrays (TMAs) containing 263 cases of GC were constructed. Assessment of CLDN18.2 expression was performed by immunohistochemistry, where it was scored as negative and positive.

Results: 14.3% (37/258) of GCs were stained with anti-CLDN18.2 antibody. While 7.8% (20/258) of all cases were positive, 92.2% (238/258) were scored as negative. There was no statistically significant difference between the two groups in terms of patient features such as age or sex, tumor grade, TNM stage, histologic subtype or overall survival.

Conclusion: CLDN18.2 expression was not associated with patient prognosis in the Turkish cohort. However, as this molecule is a potential therapeutic target, information about the impact of CLDN18.2 expression will be important in managing patients, therefore more studies are needed to learn more on the outcomes of CLDN18.2 expression on clinicopathologic features in GC.

The effect of consumer-based authenticity on attachment and social networks in digital context: Case of Moroccan’s terroir products
Authors: Ouboutaib Fatima E
Published: August 2023

The focus of this paper is to conceptualize and measure consumer-based authenticity as well as its effects on social networks (SN) and attachment. In addition, it explores the effect of consumer attachment. In order to address this focus, it suggests a framework for analyzing this relationship by using the Partial Least Squares Equation Modeling. This study utilizes applied quantitative research in the Moroccan context. The results showed that consumer-based authenticity represents a marketing tool that can influence purchase intention. The key contribution of this research is the feature of consumer authenticity that influences social network confidence. Consumers need to feel the connection with the terroir product goes beyond the digital interface as they look for a more human relationship. The virtual context may display a high risk of deficient relationships; hence, the low consumer-based authenticity.

Authors: Baleia Isabel , Santos Hugo , Almeida Patrícia , Brandão Rita , Luís Adriana , Rento Ana , Mesquita Lara , Rocha Juliana , Trindade Pedro
Published: August 2023

Introduction: Stroke presents multiple associated consequences. Due to diminished functionality, post-stroke individuals often exhibit low engagement in moderate to vigorous physical activity (PA), not reaching recommended minimum levels. PA, apart from its additional benefits, is crucial as a non-pharmacological preventative strategy, providing neuroprotective effects against neurological diseases, mitigating their impact, delaying their progression, and potentially preventing recurrences. Objective: To review and analyse studies assessing PA levels in hospitalized individuals diagnosed with stroke, via either interval or continuous monitoring for a minimum duration of six hours during the most active periods of the day. Methodology: A literature search was conducted in PubMed, PEDro, and CENTRAL databases using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. We included any types of studies that monitored PA levels in individuals aged over 18 years with stroke, who were hospitalized, and whose outcomes were not related to specific intervention effects. Results: After applying the inclusion criteria, 27 studies were included. Of these, 14 monitored PA via device-based methods, and 13 used behavioural mapping. Due to the methodological heterogeneity of the studies, it was not feasible to conduct a meta-analysis. Conclusion: Hospitalized post-stroke individuals spend large periods of time inactive and sedentary, potentially not meeting the established recommendations for PA levels in this condition.
MiR-28-3p regulates high glucose-induced endothelial dysfunction by targeting CXXC5
Authors: Wang Linjun , Fang Xin , Dong Yangmin , Wang Songmao , Pan Jun , Wu Ziheng , Qiu Chenyang
Published: August 2023

Introduction

Introduction: Data from the CEO database shows microRNA (miR) -28-3p levels are elevated in diabetic patients. Nevertheless, the role of miR-28-3p in peripheral artery disease with diabetes have not been investigated.

Material and methods

The level of miR-28-3p, CXXC5, CXXC-type zinc finger protein 5, and CXXC5’s downstream molecules as well as endothelial function were investigated. Dual luciferase analyses were used to confirm the binding site of miR-28-3p and CXXC5.

Results

Results: Under high-glucose condition, miR-28-3p expression is increased whereas CXXC5 expression is downregulated. Overexpression of miR-28-3p increased cell apoptosis and inhibited cell proliferation, migration, and vessel formation, whilst inhibiting its expression had the opposite effect. The overexpression and inhibition of miR-28-3p could also influence both the mRNA and protein levels of CXXC5 and its known downstream molecules. Analysis of bioinformatics data revealed a potential binding site for miR-28-3p and CXXC5. Dual luciferase analyses demonstrated that miR-28-3p suppressed CXXC5 expression by targeting the 3'-untranslated region (3'-UTR) of CXXC5. Following that, we overexpressed both miR-28-3p and CXXC5. The level of CXXC5 and its known downstream signaling molecules decreased with miR-28-3p overexpression alone. As anticipated, co-overexpression of miR-28-3p and CXXC5 partially reversed the effect of miR-28-3p mimics.

Conclusions

Conclusion: These findings indicated that miR-28-3p regulated high glucose-induced endothelial dysfunction by targeting CXXC5.

EFL Instructors’ Occupational Wellbeing during the COVID-19 Pandemic in Turkey: A Study of Burnout and Work Engagement
Authors: ÇAM Esra
Published: August 2023

The COVID-19 pandemic and the following online education experiences have caused significant changes in educators’ work lives and working conditions and brought extra stress factors. This mixed-methods study examined the well-being of English instructors trying to continue their teaching activities through online teaching during the pandemic in Turkey, based on the Job Demands-Resources (JD-R) Theory. Quantitative data were collected from 69 English instructors through an inventory. Semi-structured interviews were conducted with 12 instructors. The results reveal an average level of burnout and work engagement in the study sample. Uncertainty and the limitations of technology are emerging as two new job demands faced by instructors in online teaching during the pandemic. The findings also provide evidence for the possibility of adding a fourth dimension to the JD-R: personal demands. E-teaching readiness and openness to interaction as personal resources and security as a job resource have emerged as three new resources specific to the online teaching mode. Student-related factors, which were found to be causes of poor well-being in general in previous studies, have been found to be sources that promote higher well-being among instructors in online education. The study reveals important implications for school administrators and teacher educators.

Abstract. Carbon monoxide (CO) is an air pollutant that plays an important role in atmospheric chemistry and is mostly emitted by forest fires and incomplete combustion in, for example, road transport, residential heating, and industry. As CO is co-emitted with fossil fuel CO2 combustion emissions, it can be used as a proxy for CO2. Following the Paris Agreement, there is a need for independent verification of reported activity-based bottom-up CO2 emissions through atmospheric measurements.
CO can be observed daily at a global scale with the TROPOspheric Monitoring Instrument (TROPOMI) satellite instrument with daily global coverage at a resolution down to 5.5 × 7 km2. To take advantage of this unique TROPOMI dataset, we develop a cross-sectional flux-based emission quantification method that can be applied to quantify emissions from a large number of cities, without relying on computationally expensive inversions. We focus on Africa as a region with quickly growing cities and large uncertainties in current emission estimates. We use a full year of high-resolution Weather Research and Forecasting (WRF) simulations over three cities to evaluate and optimize the performance of our cross-sectional flux emission quantification method and show its reliability down to emission rates of 0.1 Tg CO yr−1.
Comparison of the TROPOMI-based emission estimates to the Dynamics–Aerosol–Chemistry–Cloud Interactions in West Africa (DACCIWA) and Emissions Database for Global Atmospheric Research (EDGAR) bottom-up inventories shows that CO emission rates in northern Africa are underestimated in EDGAR, suggesting overestimated combustion efficiencies. We see the opposite when comparing TROPOMI to the DACCIWA inventory in South Africa and Côte d'Ivoire, where CO emission factors appear to be overestimated. Over Lagos and Kano (Nigeria) we find that potential errors in the spatial disaggregation of national emissions cause errors in DACCIWA and EDGAR respectively. Finally, we show that our computationally efficient quantification method combined with the daily TROPOMI observations can identify a weekend effect in the road-transport-dominated CO emissions from Cairo and Algiers.

Abstract. Increasing the marine CO2 absorption capacity by adding alkaline minerals into the world’s oceans is a promising marine carbon dioxide removal (mCDR) approach to increase the ocean’s CO2 storage potential and mitigate ocean acidification. Still, the biological impacts of dispersion of alkaline minerals needs to be evaluated prior to its field deployment. In this study, the toxicity effect on marine microalgae of two commonly used alkaline minerals, calcium hydroxide (Ca(OH)2) and sodium hydroxide (NaOH), was compared with magnesium hydroxide (Mg(OH)2), by applying the same concentration of hydroxyl radicals (OH-) for each component. Cultures of marine green microalgae Tetraselmis suecica were exposed to NaOH, Ca(OH)2 or Mg(OH)2 in concentrations mimicking dispersion scenarios from a ship which included short-term exposure with high alkaline mineral concentration called “dispersion phase” followed by a dilution and “regrowth” phase over six days. There was no detectable effect of Mg(OH)2 treatment on algae growth either after the dispersion phase or during the regrowth phase, compared to control treatments. The Ca(OH)2 treatment resulted in very few living algal cells after the dispersion phase, but a similar growth rate was observed during the regrowth phase as was for the Mg(OH)2 and control treatments. The NaOH treatment resulted in no surviving algae after the dispersion phase and during the regrowth phase. Standardized whole effluent toxicity (WET) tests were carried out with a range of Mg(OH)2 concentrations using a sensitive marine diatom, Skeletonema costatum, which confirmed the relative low toxicity effect of Mg(OH)2. Similar biological effects were observed on natural microalgae assemblages from a local seawater source when applying the same Mg(OH)2 concentration range and exposure time used in the WET tests. The results suggest that Mg(OH)2 is relatively safe compared to Ca(OH)2 and NaOH with respect to marine microalgae.
Effects of Intermittent Aerosol Forcing on the Stratocumulus-to-Cumulus Transition

Abstract. We explore the role of intermittent aerosol forcing (e.g., ship tracks, or injections associated with marine cloud brightening) on the stratocumulus-to-cumulus transition (SCT). We simulate a three-day Lagrangian trajectory in the north-east Pacific using a large-eddy simulation model coupled to a bin-emulating, two-moment, bulk microphysics scheme that captures the evolution of aerosol and cloud droplet concentrations. By varying the background aerosol concentration, we consider two baseline systems - pristine and polluted. We perturb the baseline cases with a range of aerosol injection strategies by varying the injection rate, number of injectors, and the timing of the aerosol injection. Our results show that aerosol dispersal is more efficient under pristine conditions due to a transverse circulation created by the gradients in precipitation rates across the plume track. Furthermore, we see that a substantial enhancement in the cloud radiative effect (CRE) is evident in both systems. In the polluted system, the albedo effect (smaller but more numerous droplets causing brighter clouds at constant liquid water) is the dominant contributor in the initial two days. The contributions from liquid water path (LWP) and cloud fraction adjustments are important on the third and fourth day, respectively. In the pristine system, cloud fraction adjustments are the dominant contributor to the CRE on all three days, followed by the albedo effect. In both these systems, we see that the SCT is delayed due to the injection of aerosol, and the extent of the delay is proportional to the number of particles injected into the marine boundary layer.
