Authors: Diem My Tran Ngoc , Quang Ha Tran Le , Song Nhi La Duong
Published: July 2023

Zooplankton plays a role as a living food source in the food web of water bodies, determining the growth and development of many aquatic species, especially at the larval stage. The study has recorded 52 species of 29 genera, 21 families, 6 classes, 4 phylum and 7 types of larvae in 28 sampling sites of 3 areas for co-management of coastal fisheries. The density of plankton individuals ranged from 49300 individuals/m3 to 272812 individuals/ m3. The number of species and density of plankton individuals in Thanh An area is higher than in the other areas (Long Hoa and Can Thanh). The similarity of the zooplankton communities showed that at 40% of the sampling sites, they were divided into 2 groups as follows: group 1 of water bodies in the co-management model area in Long Hoa and Can Thanh, group 2 included the water bodies of Thanh An area. The Copepoda class is the highest proportion in the sampling sites, showing that it will be an abundant food source for the growth and development of aquatic species that are cultured or live naturally in this ecosystem. It is also an important biological factor that needs to be managed and conserved to create a natural habitat for the sustainability of fish stocks in the area.

Authors: Tran Thanh Thang , Nguyen Thi Thuy Linh
Published: July 2023

Perilla frutescens (L.) is a popular medicinal plant cultivated primarily for its pharmacological benefits. Research has recently focused on boosting crop yield without using excessive chemical fertilizers and plant growth regulators which could harm the environment and human health. One of them, methionine, has been discovered to play a crucial role in synthesizing growth-regulating compounds and accumulating secondary compounds in some plants. This study investigated the effects of methionine concentrations (0, 50, 100 and 150 mg/L) on the growth of Perilla frutescens. Agronomic, physiological and biochemical parameters were assessed. The results of the variance analysis show that spraying methionine increases the agronomic parameters. Additionally, methionine spraying increased photosynthetic and respiration rates. Compared to the control, spraying 150 mg/L of methionine increased phenolic and flavonoid accumulation by 89% and 115% respectively. These findings might provide a rationale from a scientific standpoint for cultivating Perilla frutescens to increase polyphenol content.

Published: July 2023

Denotarisia linguifolia (De Not.) Grolle, or D. linguifolia, collected from LangBiang was used to make fraction extracts used for the evaluation of biological activity. Four extracts (n-hexane, chloroform, ethyl acetate and ethanol) were assessed for antioxidant (ferric reducing power, DPPH and lipid peroxidation), enzymatic inhibition (tyrosinase, α-glucosidase and hyaluronidase), cytotoxicity against MCF-7 and phytochemistry screening. For antioxidant assays, ethyl acetate extract had the highest antioxidant capacity ferric reducing power and DPPH scavenging, while chloroform extract had the highest antioxidant capacity in lipid peroxidation. For enzyme inhibition evaluation, D. linguifolia ability in anti-tyrosinase was insignificant while its ability in anti-α-glucosidase and anti-hyaluronidase was exceptional, chloroform extract had the best ability against α-glucosidase and ethyl acetate extract had the best ability against hyaluronidase. Unexpectedly, the n-hexane extract had the best potential for preventing the proliferation of MCF-7. Finally, the phytochemistry screening revealed the presence of important secondary metabolites within the liverwort extracts such as phenolic compounds (phenols, quinones, coumarins and flavonoids) and glycosides (saponins and cardiac glycosides).

Published: July 2023

Breast cancer is the most commonly occurring malignant neoplasm among the female population. This study aims to ascertain novel biomarkers that may prove advantageous in the early detection of breast cancer. The present investigation involved a comparative analysis of the plasma expression of four distinct microRNA (namely, miR-425-5p, miR-142-3p, miR-9-3p and miR-15b-5p) in a cohort of 80 Vietnamese patients who were newly diagnosed with breast cancer. The expression levels of these microRNA were compared with those of 80 healthy individuals who served as controls. The plasma total RNA was extracted and the miRNA expression levels were assessed using Stem-loop RT-qPCR followed by statistical analysis. According to the findings of our study, the plasma levels of four microRNAs namely miR-425-5p, miR-142-3p, miR-9-3p and miR-15b-5p, were significantly reduced in both breast cancer patients in stage 0-I and the general breast cancer patient population as compared to healthy controls. The diagnostic accuracy of both miR-9-3p levels and miR-15b-5p levels was satisfactory with 74% and 88% values respectively. The combined effect of miR-425-5p/miR-142-3p/miR-9-3p/miR-15b-5p revealed the highest level of diagnostic precision, attaining a rate of 98% and an area under the curve value of 0.98 (with a sensitivity of 87.5% and specificity of 100%). In summary, the microRNAs miR-425-5p, miR-142-3p, miR-9-3p and miR-15b-5p exhibit potential as non-invasive diagnostic biomarkers for breast cancer, particularly in the initial stages of the disease.
Dynamic surface reconstruction of perovskite oxides in oxygen evolution reaction and its impacts on catalysis: a critical review
Authors: Hu Zhonghui , Yan Qian , Wang Yuanqing
Published: July 2023

Perovskite oxides have gained significant attention in recent years due to their superior catalytic activity in the oxygen evolution reaction (OER). However, the identification of the active structure and corresponding catalytic mechanism for these oxides still remains elusive, particularly for complex perovskite oxides. This is due to the intricate surface reconstruction that may occur under working conditions and the differing reaction mechanisms. This paper aims to address these issues by providing an overview of OER, perovskite oxides, characterization methods, and factors affecting surface reconstruction during OER. Specifically, the paper reviews in-situ and operando characterization studies conducted over the last decade, focusing on the surface dynamic structural evolution of simple and complex perovskite oxides such as SrIrO3 and Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF). The paper concludes by presenting an overview of reported active structures on perovskite oxides so far, and providing guiding principles for the design of highly active and stable catalysts. By addressing these issues, this paper provides valuable insights into the design and development of effective catalysts for OER.
Directed Crystallization of a Nanoscale Quasi-1D van der Waals Topological Insulator
Authors: Allison Steven , Cordova Dmitri Leo , Hasib Maham , Aoki Toshihiro , Arguilla Maxx
Published: July 2023

Anisotropy often yields unexpected structures and properties in the solid state. In van der Waals (vdW) solids comprised of 1D or quasi-1D (q-1D) chains, anisotropy in both intra- and inter-chain directions results in an abundance of packing motifs and altered physical states. Q-1D vdW solids with topologically protected states are most sought after due to their potential as building blocks for quantum and spintronic devices. Yet, access to such facet- and edge-specific states is limited by the stochastic nature of micromechanical exfoliation. Here, we demonstrate that Bi4I4, a q-1D vdW topological insulator, can be crystallized from the vapor phase either into nanowires or quasi-2D nanosheets. We find that gold nanoparticles (Au NPs) on the growth substrate, in conjunction with the anisotropic structure of Bi4I4, direct the dimensionality of Bi4I4 nanostructures. Systematic variation of Au NP diameters, Bi:I precursor ratios, and growth-deposition temperatures reveal that Au NPs generally act as nucleation sites for vapor-solid growth of nanowires. Post-synthesis analyses of 20 nm Au NPs show that the 1:1 ratio of Bi to I within the Au NPs uniquely triggers the vapor-liquid-solid growth of [001]-oriented nanosheets from laterally-ordered [Bi4I4]n chains along the [100] direction. We rationalize the bimodal growth pathways and the morphologically distinct nanostructures based on crystallization habits of the nanostructures, Bi:I ratios in the Au NPs post-synthesis, and orientation of stereochemically active Bi lone pairs between adjacent chains. We anticipate that these pathways are adaptable to other halide- and chalcogen-based 1D vdW nanocrystals with diverse physical and quantum properties.

Published: July 2023

Sulfilimines, the aza-analogues of sulfoxides, are of increasing interests in medicinal and agrochemical research programs. However, the development of efficient routes for their synthesis remains relatively unexplored. In this study, we report a transition metal-free, selective S-arylation reaction between sulfenamides and arynes, enabling the facile preparation of structurally diverse sulfilimines under mild and redox-neutral condition in good yields. The application value of our method was further demonstrated by scale-up synthesis, downstream derivatization, and robustness screen.

The oxidative coupling of methane (OCM), which offers a direct route for converting methane into higher-value ethylene. Despite the development of selective catalyst formulations, kinetic and reactor design studies have been hampered by a lack of data for truly isothermal, relevant. Because of exothermicity issues, the temperature of a fixed-bed reactor filled with Mn-Na2WO4/SiO2 catalysts show a sudden temperature run-away accompanied with a drastic loss of selectivity. The objective of this study is to measure catalyst activity under relevant reaction conditions of pressure (3 bar), biogas composition (no dilution) and contact time, while keeping the process as isothermal as possible. To this aim, we have synthesized and shaped a trilobed Mn-Na2WO4/α-Al2O3 catalyst, which may be used as is at industrial scale, and measured its performance in a single-pellet reactor. We found that the presence of CO2 does not degrade catalyst performance, even on long run, which should enable the use of a CO2-rich stream such as biogas. Actually, higher methane conversions have been obtained in the presence of CO2, likely due to a possible contribution of methane dry reforming reaction. We also noticed a slow catalyst activation over the first 100 hours while selectivity was kept constant.

Authors: Jin Ping , Yin Bao-Min
Published: July 2023

Background: The study aimed to assess the efficacy and safety of dinoprostone vaginal insert in labor induction following optimization of standard operating procedure (SOP) and to discover independent predictors of vaginal delivery. Methods: This study comprised 551 pregnant women who required cervical ripening with dinoprostone before induction of labor. Using univariate and multivariate analyses, independent predictors of vaginal delivery were identified. Results: 443 of the 551 women (80.4%) gave birth vaginally. Vaginal delivery was predicted by maternal age (24–30 vs. < 24, P < 0.001; 30–35 vs. < 24, P = 0.03), gestational age (P = 0.005), birth weight (P < 0.001), parity (P = 0.001), pre-pregnancy BMI (P < 0.001), premature rupture of membranes (P = 0.001), meconium-stained amniotic fluid (P < 0.001), fundal height (P < 0.001) and the Bishop score (P < 0.001). None of the women exhibited severe postpartum hemorrhage. Conclusions: The maternal age, gestational age, birth weight, parity, body mass index, premature membrane rupture, amniotic fluid contamination, fundal height, and the Bishop score were independent predictors of vaginal delivery. These may guide the clinical use of dinoprostone for induction of labor.

Published: July 2023

Diesel poisoning is a rare clinical condition. On September 27, 2021, a 55-year-old male who mistakenly inhaled 20 mL of diesel through a siphon was admitted to our hospital. The main symptoms were cough and asthma. Chest computed tomography (CT) showed both lungs scattered with patchy consolidation, ground-glass shadow, exudation, and pleural effusion. After 61 days of lung rehabilitation training and other supportive treatment, including oxygen therapy, postural drainage, ventilator support, bronchoalveolar lavage, hemoperfusion, continuous renal replacement therapy (CRRT), hormones, and antibiotics, the patient’s condition improved, and the patient was discharged. Through literature review, we found that lung consolidation, ground-glass shadow, nodular lesions, and pleural effusion can be observed on chest images of patients with lipoid pneumonia, with severe cases showing diffuse lesions involving both lungs, possibly secondary to respiratory failure. Children with acute critical illness deteriorates rapidly and have poor prognosis, whereas adults or patients with chronic poisoning have better prognosis after active treatment.

Published: July 2023

Objective: To explore the work experience of medical staff in the emergency department of a general hospital in the triage of patients with non-traumatic acute abdomen to formulate corresponding intervention measures and branch evaluation tools. Methods: With descriptive phenomenology as the research method, semi-structured interviews were conducted with the medical staff in a tertiary hospital in Nanjing from February 1st to 10th, 2023, and Colaizzi seven-step analysis was used to analyze the data. Results: A total of 17 emergency medical staff were interviewed in this study. Four themes were derived from the analysis of the data: the etiology of acute abdomen is complex, so it is difficult to categorize them: acute abdomen requires immediate treatment, but the treat will be delayed if the categorization is inaccurate; the high pressure of nurses and the accuracy in categorizing the patients are problems that should be addressed. Conclusion: The categorization of patients with non-traumatic acute abdomen is challenging. Therefore, it is necessary to carry out corresponding intervention and formulate appropriate departmental evaluation tools to improve the accuracy of categorization of patients with acute abdomen.

Published: July 2023

Background. Diabetic retinopathy as a complication of diabetes mellitus and age-related macular degeneration are the most common causes of vision loss in the working population. The main features of these diseases include their asymptomatic course in the early stages of development. Early diagnosis of retinal pathologies and, as a result, early complex treatment, can greatly slow down the progression. The diagnosis is made by highly qualified specialists, but with the development of machine learning, there is the possibility of automated screening of retinal pathologies on digital images of optical coherence tomography of the eye. The purpose of this study is to develop a mathematical model for diagnosing retinal pathology in optical coherence tomography images of the eye. Materials and methods. An open database of images of optical coherence tomography of the eye was used as materials. All images were classified into four classes, of which three classes are different retinal pathologies. The following models were used as multidimensional models: logistic regression, naive bayes classifier, random forest, nearest neighbors, support vector machine, neural network, convolutional neural network. Results. Most of the models showed accuracy below 70%. The best result is obtained by the convolutional neural network with a result of 89.7%, followed by the support vector machine with an accuracy of 71.1% and the neural network with 70.8%. Conclusion. As a result, the use of multidimensional models, in particular convolutional neural networks, can show a high accuracy value, which allows using this model as a program to support medical decision making.

The modern lifestyle of young people is reflected in the state of hearing. Using gadgets and listening to loud music leads to the early development of hearing loss. The purpose of the study is to assess the condition of the auditory analyzer in students. The results of our own research allowed us to identify the main factors leading to hearing loss and assess the condition of the auditory analyzer in 20 students aged 20-22 years. Data collection was carried out on the basis of comprehensive surveys, questionnaires and reports. To assess hearing, anamnesis was collected, external examination of the ear, palpation, otoscopy, whispering and colloquial speech, tests with tuning forks, tonal threshold audiometry at four typical frequencies. The results of the study of the condition of the auditory analyzer showed that in 10% of cases sulfur plugs were detected in the external auditory canal, in 5% of cases – the presence of scars and pathological color of the membrane. The study of auditory function revealed that in 20% of cases, whispered speech was detected from a distance of 4 meters, and not from 6. The values of air and bone conduction during the Rinne test in all cases did not reach the standard values, in 20% of cases the test on the right ear was negative, and on the left ear – in 10%. In Federici's experiment, it was revealed that in 15% of cases, bone conduction was higher than air. The results of the Weber test showed that in 45% of cases the sound was shifted and uneven. The data obtained using a high-frequency tuning fork 2048 showed that in 85% of cases, the air conductivity values of both the right and left ears were below normal values. The study of hearing acuity demonstrated that in 15% of cases the values reached the upper limit of the norm. The results of the questionnaire to identify the determining factors showed that 30% of students noticed hearing impairment. More than 50% of students answered that they often listen to loud music and use headphones. Thus, the main risk factors and the first signs of hearing loss in students were identified.

Published: July 2023

Introduction: Autism spectrum disorder is a widespread disorder characterized by changes in various body systems. Sensory area of patients: It is a heterogeneous neuropsychiatric disorder with a deficit of perception of sensory information, and with expressed disorders in the sphere of communication and speech underdevelopment and limited interests. Motor skills of children: unexpected, spontaneous movements of various parts of the body, and violations of the sequence of basic, habitual actions. Impaired psychomotor development in autism: There is a possibility that the distortion of the mirror neuron system may lead to a lack of speech function, which may cause a lack of ability to learn through imitation mechanisms. Identification, diagnosis of mental development, organization of help: Observations, conversations and medical documentation make it possible to draw a conclusion about the affective development of the child. Principles of medication correction: consist in individual selection of remedies and methods in each individual case and are determined by the child's behavior. Regular and long-term work of qualified specialists consists in selecting the necessary therapy, which includes neuroleptics-risperidone and aripiprazole to reduce negativity, aggression, but they have side effects in the form of carbohydrate metabolism disorders. Conclusion: The article points out the main general task of supporting children with autism spectrum disorders, which is the pursuit of achieving the highest possible level of social adaptation and socialization, which involves knowing the attitudes toward children with autism of different layers of society - from family members to outsiders.

La rinosinusitis crónica (RSC) es una afección que incide en gran porcentaje sobre la población pediátrica y se define como la obstrucción o bloqueo nasal causado por secreción nasal en conjunto con dolor o presión facial y tos durante 12 semanas, que presenta signos endoscópicos o cambios en la tomografía computarizada (TC) compatibles con la enfermedad. El tratamiento es la terapia médica que consiste en antibióticos orales, esteroides intranasales e irrigaciones nasales con solución salinal. Sin embargo, en algunos casos, puede ser necesaria la cirugía cuando falla la terapia médica o en casos de rinosinusitis aguda complicada. Las intervenciones quirúrgicas que se emplean consisten en adenoidectomía con irrigación antral, sinuplastia con balón y cirugía endoscópica de senos paranasales (ESS). A pesar de que la (ESS) resulta ser la cirugía por excelencia por ser la más eficaz y con porcentajes en resultados positivos bastante significativos, es probable que no sean aprovechadas en su totalidad las capacidades de dicha intervención por el temor a las complicaciones que se presentan dada la anatomía tan pequeña. En tal sentido, por medio de la siguiente revisión de bibliografía se puntualizan los avances de este tipo de cirugía en niños.

The eight new concepts of picture fuzzy sets in UP (BCC)-algebras are introduced by Kankaew et al. in 2022. This idea is extended to the lower and upper level subsets of picture fuzzy sets in UP (BCC)-algebras. Moreover, we define a picture fuzzy set in the same way as a characteristic function and study its characterizations from the related subset.

COVID-19 Pandemic and the Use of Emergency Remote Teaching (ERT) Platforms: Lessons From a Nigerian University
Authors: Oyewole Olawale , Onaolapo Sodiq
Published: July 2023

Aim/Purpose: This study examines the use of the Emergency Remote Teaching (ERT) platform by undergraduates of the University of Ibadan, Nigeria, during the COVID-19 pandemic using the constructs of the UTAUT2 model. Five constructs of the UTAUT2 model were adopted to investigate the use of the ERT platform by undergraduates of the university.

Background: The Coronavirus (COVID-19) outbreak disrupted academic activities in educational institutions, leading to an unprecedented school closure globally. In response to the pandemic, higher educational institutions adopted different initiatives aimed at ensuring the uninterrupted flow of their teaching and learning activities. However, there is little research on the use of ERT platforms by undergraduates in Nigerian universities.

Methodology: The descriptive survey research design was adopted for the study. The multi-stage random sampling technique was used to select 334 undergraduates at the University of Ibadan, Nigeria, while a questionnaire was used to collect data from 271 students. Quantitative data were collected and analyzed using frequency counts, percentages, mean and standard deviation, Pearson Product Moment Correlation, and regression analysis.

Contribution: The study contributes to understanding ERT use in the educational institutions of Nigeria – Africa’s most populous country. Furthermore, the study adds to the existing body of knowledge on how the UTAUT2 Model could explain the use of information technologies in different settings.

Findings: Findings revealed that there was a positive significant relationship between habit, hedonic motivation, price value, and social influence on the use of ERT platforms by undergraduates. Hedonic motivation strongly predicted the use of ERT platforms by most undergraduates.

Recommendations for Practitioners: As a provisional intervention in times of emergencies, the user interface, navigation, customization, and other aesthetic features of ERT platforms should be more appealing and enjoyable to ensure their optimum utilization by students.

Recommendation for Researchers: More qualitative research is required on users’ satisfaction, concerns, and support systems for ERT platforms in educational institutions. Future studies could consider the use of ERT by students in different countries and contexts such as students participating in English as a Foreign Language (EFL) and the English for Speakers of other languages (ESOL) programs.

Impact on Society: As society faces increased uncertainties of the next global pandemic, this article reiterates the crucial roles of information technology in enriching teaching and learning activities in educational institutions.

Future Research: Future research should focus on how different technology theories and models could explain the use of ERT platforms at different educational institutions in other geographical settings and contexts.

Bu çalışmada, düz bir yüzeye çarpan sınırlandırılmamış ve sınırlandırılmış türbülanslı dairesel hava jetlerinde çarpma yüzeylerindeki ısı transferi etkileri deneysel olarak incelenmiştir. Çarpma levhası yüzeylerinde termal kamera ile gerçekleştirilen sıcaklık ölçümlerinden, çarpma levhası orta ekseni boyunca sıcaklık dağılımları elde edilmiştir. Elde edilen sıcaklık dağılımlarından, Reynolds sayısının, lüle-levha arası açıklığın ve sınırlayıcı levha durumunun çarpma levhası üzerindeki Nusselt dağılımlarına etkisi araştırılmıştır. İncelenen tüm akış alanlarında, çarpma levhası üzerindeki Nusselt değerlerinin artan Reynolds sayısı ile arttığı, artan lüle-levha arası açıklık ile azaldığı görülmüştür. Akış alanlarında sınırlayıcı levhanın varlığı, çarpma levhası üzerindeki Nusselt değerlerini azaltmaktadır.

The current study empirically investigated the implementation of relational e-HRM practices in banks and examined their relationship with the overall organizational performance of the banks in Lahore during COVID-19 pandemic. It also highlighted the issues that managers face during the implementation of relational e-HRM practices. The mixed method approach was adopted to conduct this cross-sectional study. Commercial banks with their head offices in Lahore were chosen and 171 branches were selected randomly. The purposive sampling technique was used to collect qualitative data and semi-structured interviews of sixteen (16) branch managers were carried out online. Qualitative data was analyzed thematically while covariance-based structural equation modeling (CB-SEM) was used to understand the effect of e-HRM practices on organizational performance. Most of the banks were found to have implemented all the relational e-HRM practices except e-selection which was implemented only in two branches. Relational e-HRM practices showed a positive effect on the overall performance of banks during COVID-19 pandemic. Centralized decision- making, limited autonomy of bank branches, presence of senior, computer illiterate employees, and inadequate financial resources were found to obstruct the implementation of e-HRM practices. The current research added to the e-HRM literature and examined the association between relational e-HRM practices and overall organizational performance in the context of banks operating in Lahore which apparently was never done before. Only the top commercial banks operating in Lahore, one of the largest metropolitans in Pakistan, were included in this study. The generalizability of findings may be enhanced with further studies.

Kadar nitrit dalam sarang burung walet (SBW) telah menjadi perhatian dalam beberapa tahun terakhir. SBW yang diekspor dari Indonesia ke Negara Tiongkok harus memenuhi standar kadar nitrit (NO2), yaitu maksimum 30 ppm. Dinamika perkembangan teknologi dan jaman saat ini menuntut instrumen pengujian kadar nitrit secara akurat, diantaranya menggunakan spektrofotometer dan kromameter. Penelitian ini mengkaji kadar nitrit pada SBW bersih yang telah dilakukan pencucian asal Pulau Sumatera dengan menggunakan metode spektrofotometer dan mengevaluasi warna menggunakan kromameter berbasis sistem CIE pada parameter L*, a*, b*, C*, dan h*. Jumlah sampel ditentukan secara purposif dari rumah burung walet (RBW). Sebanyak 18 sampel SBW berasal dari berbagai wilayah di Sumatera. Sampel SBW diuji kadar nitritnya menggunakan spektrofotometer di Balai Besar Uji Standar Karantina Pertanian (BBUSKP) Jakarta dan kromameter diuji di laboratorium Ilmu Teknologi Pangan IPB, Bogor. Hasil kadar nitrit pada SBW menunjukkan bahwa persentase kadar nitrit di bawah 30 ppm adalah 72,22%. Nilai rata-rata L* pada grup A (kadar nitrit >30 ppm) dan B (kadar nitrit <30 ppm) secara berurutan adalah sebesar 67,65±1,97 dan 68,47±5,25. Hasil analisis statistik dengan uji-t menunjukkan tidak terdapat perbedaan yang signifikan (p>0,05) antara nilai L*, a*, b*, C* dan *h pada kedua grup. Metode kromameter tidak dapat digunakan sebagai metode tunggal dalam mengukur kadar nitrit pada SBW serta tidak dapat membedakan secara signifikan warna SBW yang berasal dari RBW yang berbeda.
