Authors: Huang Xiaoshan , Li Shan , Wang Tingting , Lajoie Susanne P. 
Published: January 2024

Abstract
In this study, we explored the relationships among students’ perceived challenges in collaborative learning, emotion regulation strategies (i.e., reappraisal and suppression), and emotion synchrony (i.e., valence synchrony and arousal synchrony) in natural classroom settings. We performed the partial least squares structural equation modeling (PLS-SEM) method for data analysis. The results revealed a positive and direct effect of cognitive reappraisal on arousal synchrony, and a negative and direct effect of cognitive reappraisal on valence synchrony. Moreover, students’ perceived challenges in collaborative learning had a negative effect on their arousal synchrony. Students’ perceived challenges also played a mediating role in the relationship between cognitive reappraisal and arousal synchrony. As a total effect, cognitive reappraisal still positively and significantly predicted arousal synchrony. This study provided insights into students’ emotional responses in collaborative learning and informed the design of collaborative learning environments. This study has also methodological implications regarding the analysis of emotion synchrony.
Evaluating the Underreporting of Diseases in the Philippines During the COVID-19 Pandemic through Comparative Forecast Analysis
Authors: Parreño Samuel John 
Published: January 2024

Abstract

Background
The COVID-19 pandemic has significantly impacted global health systems, particularly in the Philippines. The redirection of healthcare resources towards COVID-19 has raised concerns about the potential underreporting and surveillance of other communicable diseases. This study explores whether the pandemic has led to the underreporting of these diseases.
Methods
The study employs Predictive Mean Matching (PMM) for data completeness and uses Seasonal Autoregressive Integrated Moving Average (SARIMA), Neural Network Autoregressive (NNAR), and Holt-Winters (HW) models for disease forecasting. The actual reported cases of diseases for the years 2020 and 2021 are compared with the forecasts to identify discrepancies.
Results
Significant underreporting was observed for most diseases studied, with notable exceptions such as AFP. NNAR models outperformed SARIMA and HW in forecasting accuracy. Diseases like Measles, Diphtheria, and Rubella showed substantial underreporting, while vector-borne diseases like Dengue and Chikungunya, and waterborne diseases such as Typhoid Fever and Cholera, also indicated underreporting.
Conclusions
The study reveals significant underreporting of various diseases in the Philippines during the COVID-19 pandemic. The effective use of advanced predictive models underscores the potential of these tools in enhancing disease surveillance and highlights the need for robust health systems capable of sustaining surveillance during crises.

Published: January 2024

Abstract
The corrosion method offers a viable means to fabricate efficient electrocatalysts for electrochemical reactions, ensuring strong adhesion between the substrate and the formed material and minimizing resistance between the catalyst and the electrode. This study introduces a method for synthesizing a high-performance oxygen evolution reaction (OER) catalyst by cultivating a transition metal-based multimetallic hydroxide on Ni foam via corrosion. The hydroxide, comprising Ni, Fe, Co, Mn, and Cr, uniformly coated the Ni foam, ensuring even distribution of each transition metal within the catalyst. The resultant NiFeCoMnCr hydroxide catalyst demonstrated enhanced OER performance, evidenced by reduced overpotential and improved stability, outperforming binary, ternary, and quaternary hydroxides.
Severity assessment of central nervous system infections by determining the level of myeloperoxidase protein in neutrophil extracellular traps (NETs) in cerebrospinal fluid: a retrospective case-control study
Authors: Han Song , Yang Suge , Wang Yun 
Published: January 2024

Abstract
Background and objectives:
Central nervous system (CNS) infections, represented by encephalitis, are life-threatening conditions frequently encountered by neurologists. Timely and accurate diagnosis is essential for implementing effective treatment. The objective of this study is to explore the impact of central nervous system infectious diseases on patient prognosis through the detection of myeloperoxidase (MPO) protein in neutrophil extracellular traps (NETs) in cerebrospinal fluid.
Methods
This retrospective case-control study was conducted in the Neurology Ward of Shandong University Second Hospital, involving patients diagnosed with infectious encephalitis confirmed by PCR and other methods from January 2018 to January 2024. The presence of MPO protein in the cerebrospinal fluid of the patients was measured using an ELISA method.
Results
We enrolled 50 patients diagnosed with infectious encephalitis by means of PCR testing and divided them into three groups: purulent meningitis (n = 25), viral encephalitis (n = 25), and a control group of non-infectious disease patients (n = 25). After normalality testing, there was a significant difference in the MPO content between the purulent meningitis group and the other two groups (P<0.0001). We subsequently analyzed the general data of the purulent meningitis group and the control group, and found that blood leukocyte count, cerebrospinal fluid (CSF) leukocyte count, and CSF protein content were also different between the two groups. Correlation analysis revealed a high correlation between MPO and blood leukocyte count (R2 = 0.36, P = 0.0015), CSF leukocyte count (R2 = 0.53, P<0.0001), and CSF albumin content (R2 = 0.34, P = 0.0019), indicating that MPO could serve as one of the diagnostic indicators for purulent meningitis. Using the ROC curve analysis, we found that when MPO ≥ 14.625ng/ml, the prognosis of purulent meningitis was poor, with slow patient recovery, and an accuracy of 98.7%.
Conclusion
The measurement of MPO levels in cerebrospinal fluid samples obtained after admission can aid in the diagnosis of Suppurative meningitis.
Modeling distribution and evolution of loess pore structure by two- dimensional distinct element method analyses
Authors: Zhu Yongfeng , Fan Wen 
Published: January 2024

Abstract
The macroscopic mechanical properties of loess are greatly influenced by its microstructure. In this study, the pore structure evolution of loess was investigated by using the distinct element method (DEM). And image processing techniques were employed to quantify the distribution and evolution of pore structure during shearing. The results indicate that the failure process of the numerical sample was mainly controlled by the shear stress and force chains located in the shear band rotated from the initial vertical direction to the shear band inclination under the biaxial compression. The increase of the porosity within the shear band is the main reason of the local volumetric dilation of the shear band. With the increasing axial strain, the proportion of small pores gradually increases, while the proportion of mesopores gradually decreases. The distribution of the pore axis ratio changes slightly, but the distribution of pore orientation is consistent in the evolution of the shear band. Meanwhile, the pores within the shear band are enlarged and then divided into smaller pores gradually, but the upper and lower pores of the shear band have a slight difference. These results provide a deeper insight into the distribution and evolution of pore structure in the loess sample with a shear band during shearing.

Published: January 2024

Abstract

Defects, such as scratches, cleavage fracture, and cleavage pit, occur during surface processing and affect the surface integrity of β-Ga2O3(100) substrates. This study analyzed the effects of polishing materials (polyurethane, lead, and copper) and substrate surface temperatures (25, 10, and 0 ℃) on the polishing results to overcome the effects of such defects on the substrates. Vickers indentation test was used to detect the effects of the material and surface temperature on the hardness of the disc and substrate, respectively. Machining was verified by conducting ball-disk friction wear and polishing experiments. The experimental results indicate that the material of the polished optical disc significantly affected β-Ga2O3(100) during surface processing. The higher the hardness of the polished optical disc, the greater is the material removal rate (MRR) of substrate surface, and more serious is the surface cleavage phenomenon. A lead disc with lower hardness can be used to process β-Ga2O3(100) for realizing a higher MRR, thereby effectively avoiding cleavage fractures and obtaining a surface roughness (Ra) and scratch depth of 3.4 nm and 18 nm, respectively. The hardness and mechanical strength of the substrate can be enhanced at low temperatures, and the indentation depth becomes smaller under the action of external forces, effectively inhibiting the formation of scratches and pits on the surface of the substrate during polishing. After polishing the substrate at 0 ℃, the Ra, scratch depth, and total number of cleavage pits were 2.2 nm, 14.3 nm, and 246, respectively. Compared with 25℃, Polishing the substrate at 0 ℃ decreased the Ra, scratch depth, and number of cleavage pits by 35.3, 20.6, and 34.9%, respectively. At 0 ℃, the substrate effectively avoided cleavage fracture and inhibited scratch and pit formation, thereby significantly improving the polishing effect.

Authors: Abraham Jessy , Therese A Maria 
Published: January 2024

Abstract
Background
The world-wide COVID-19 pandemic was brought on by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) coronavirus outbreak1. Its rapid spread, virulence, fatality in severe cases, and lack of a known cure make it a serious threat to human life and health and have a detrimental impact on people's mental health. There is a unique risk of exposure to environmental and occupational hazards in the nursing profession2. During COVID19, nurses who were responding to a health emergency encountered numerous difficulties. A significant nursing concern is that nurses experienced psychological distress, high workloads during uncertain times, and burnout, which can result in symptoms of depression and anxiety3. Objective of the study were to assess the level of professional quality of life of nursing officers who worked in covid19 units. Methodology: Quantitative research approach and a simple random sampling technique used to select 110 samples. The data collection tool used was the Professional quality of life scale (PQOLS).
Results
The findings of the study reveals that among 110 samples majority 67.3% of the nursing officers show low levels of compassion satisfaction. 90% of them, exhibit moderate burnout. Moderate secondary traumatic stress was present in 86.4% of the nursing officers.
Conclusion
The COVID-19 pandemic has had a significant impact on nursing officers' professional quality of life4. They need to be enabled and encouraged to take care of themselves in order to continue offering uninterruptible, high-quality care5.

Authors: Khanafer Ali , Henkes Hans , Bücke Philipp , Hennersdorf Florian , Bäzner Hansjörg , Forsting Michael , von Gottberg Philipp 
Published: January 2024

Abstract
Background
Acute stroke treatment with intracranial thrombectomy and treatment of ipsilateral carotid artery stenosis/occlusion (“tandem lesion”, TL) in one session is considered safe. However, the risk of stent restenosis after TL treatment is high, and antiplatelet therapy (APT) preventing restenosis must be well balanced to avoid intracranial hemorrhage. We investigated the safety and 90-day outcome of patients receiving TL treatment under triple-APT, focused on stent-patency and possible disadvantageous comorbidities.
Methods
Patients receiving TL treatment in the setting of acute stroke between 2013 and 2022 were analyzed regarding peri-/postprocedural safety and stent patency after 90 days. All patients received intravenous eptifibatide and acetylsalicylic acid and one of the three drugs prasugrel, clopidogrel, or ticagrelor. Duplex imaging was performed 24h after treatment, at discharge and 90 days, and digital subtraction angiography was performed if restenosis was suspected.
Results
176 patients were included. Periprocedural complications occurred in 2.3% of the patients at no periprocedural death, and in-hospital death in 13.6%. Discharge mRS score was maintained or improved at the 90-day follow-up in 86%, 4.54% had an in-stent restenosis requiring treatment at 90 days. No recorded comorbidity considered disadvantageous for stent patency showed statistical significance, the duration of the endovascular procedure had no significant effect on outcome.
Conclusion
TL treatment with triple APT resulted in a lower restenosis rate, comparable rates of sICH and mRS in comparison to single and dual APT. Aggressive APT in the initial phase may therefore prevent recurrent stroke better than restrained platelet inhibition. Comorbidities did not influence stent patency.
Study on the mechanism and control of strong ground pressure in the mining of shallow buried close-distance coal seam passing through the loess hilly region
Authors: He Yanpeng , Huang Qingxiang , Ma Li 
Published: January 2024

Abstract
Shallow buried close-distance coal seam (SBCCS) is widely found in northern Shaanxi, China. In the process of mining under the loess hilly area (LHA) in SBCCS, many accidents of strong ground pressure have occurred. Taking the in the Zhangjiamao Coal Mine as the background, this study revealed the mechanism of high ground pressure when the working face of lower coal seam passes through the surface loess hilly region. On-site measurements, physical similarity simulation, numerical calculation, and theoretical analysis were combined to study the mining process of SBCCS. The movement characteristics of the activated structure of the interval strata of the lower coal seam were analyzed. The dynamic load and the change pattern of the front abutment pressure (FAP) of the support during the loading stage of entering and exiting the loess hilly were determined. A coupled structural mechanics model of the overlying activated voussoir beam and the step voussoir beam rock beam of the interval strata was established, revealing the dynamic loading mechanism of strong ground pressure during passing through the LHA . The results showed that the dynamic load of the working face was the highest in areas affected by the load of the LHA, followed by the load while entering the LHA , the peak value of the FAP in the load-influenced LHA was high, which was approximately 1.12 times that after leaving the load-influenced LHA and 1.61 times that before entering this area. By establishing a mechanical model of the roof coupling structure when entering and exiting the load-influenced LHA, it was revealed that the dynamic load of the support while mining under the goaf in the LHA is mainly due to the synchronous movement of the activated structure of the collapsed roof of the upper coal seam and the interval rock structure. The load in the LHA was transmitted to the interval rock structure through the activated structure, resulting in a high dynamic load on the support. The study concluded that the determination of the support resistance of the working face should be based on the high-period compressive load of the synchronous movement of the roof structure in the loess hilly beam area. Through the engineering practice of hydraulic fracturing, the roof structure of the interval strata is changed, which can effectively reduce the dynamic pressure disaster of the working face. The research provides a scientific basis for the safe and efficient mining of shallow coalfields, and it provides reference for similar mining.
Quantitative Analysis of Ganglion Cell-Inner Plexiform Layer Thickness, Inner Plexiform Layer Integrity, and Macular Vascular Density in High Myopia Using Optical Coherence Tomography Angiography
Authors: Wang Lu , Lin Bin-wu , Zhang Can-yang , Pang Long 
Published: January 2024

Abstract

Background
A thinner ganglion cell-inner plexiform layer (GC-IPL) and inner plexiform layer (IPL) are indicative of several ophthalmic and central nervous system diseases. We aim to To investigate alterations in the thickness of the GC-IPL and IPL, as well as their relation to changes in macular microvasculature, in patients with high myopia.
Methods
Optical coherence tomography (OCT) and OCT-angiography (OCT-A) were performed on patients with high myopia (HM) and non-HM individuals. Comparative analysis was conducted to assess the thickness of the choroid, macula, GC-IPL, IPL, and macular superficial and deep vascular density (VD). Additionally, correlations between GC-IPL and IPL thickness with axial length or macular vascular density were examined.
Results
The results showed that HM eyes exhibited a significantly thinner subfoveal choroid and macular thickness (MT) in the 6 mm area than non-high myopia eyes (p < 0.05). In the 3 mm area, HM eyes had a lower average thickness of GC-IPL and IPL with some partial areas also showing reduced thickness (p < 0.05). Within the 6 mm area, HM eyes had significantly thinner GC-IPL and IPL overall. The ratios of GCIPL/MT and IPL/MT were smaller in HM eyes in both total and partial areas within the 6 mm area (all p < 0.05), but no difference was observed in the 3 mm area. The macular vascular density, both in the superficial and deep retinal layers, was lower in HM eyes (p < 0.05). Correlations were found between the macular vascular density and the GC-IPL and IPL within 6 mm (p < 0.005), but no linear relationship was observed between the thickness of the GC-IPL, IPL, and axial length.
Conclusion
High myopia eyes exhibited significant thinning of both the GC-IPL and IPL, possibly due to reduced vascular density in the retina. This thinning of the GC-IPL and IPL may indicate that neurodegenerative processes may commence prior to the development of maculopathy associated with high myopia.

Abstract

Background:
The pursuit of medical education is challenging and sometimes it can affect the overall quality of life of medical students. Assessing the quality of life of medical students is the first step to prepare efficient future healthcare professionals. This study used WHOQOL-BREF (World Health Organization Quality of Life Brief Version) questionnaire to evaluate the quality of life of medical students in Karachi, Pakistan.
Materials and Methods:
A cross-sectional study was conducted among 344 medical students belonging to different medical universities in Karachi, Pakistan. The WHOQOL-BREF (World Health Organization Quality of Life Brief Version) questionnaire was used to assess QOL, which included 26 items covering four domains: physical, psychological, social, and environmental. All scores for domains ranged from 4 to 20. Scoring was done according to the WHOQOL-BREF procedure manual. The questionnaire was disseminated using Google Forms among medical students. SPSS software was utilized to analyze the data. The reliability was evaluated by implementing Cronbach's alpha, and the validity was confirmed by applying the Kaiser-Meyer-Olkin (KMO) test. For each variable and QoL domain, descriptive statistics were computed, including frequencies, percentages, averages, and standard deviations. Domain scores were compared employing a t-test and one-way ANOVA, with p values less than 0.05 indicating statistical significance.
Results:
Among the 344 medical students, 56.7% (n = 195) were females while 43.3% (n = 149) were males. The WHOQOL-BREF demonstrated excellent reliability with Cronbach’s alpha value of 0.918. Most medical students rated their overall QOL (62.2%) and health satisfaction (46.8%) as good with being able to get around well (71.3%). No significant gender differences were found across the various QOL domains. Martial status significantly impacted the QOL scores with p < 0.005. Single students had significantly higher QOL scores than married/separated/divorced students. Overall, environmental domain had the highest mean score (26.81 ± 6.17), while social relationships had the lowest mean score (9.68 ± 2.93).
Conclusion:
The study findings provide valuable insights into the QoL of medical students. Most participants reported moderate satisfaction with their physical health while lower satisfaction with psychological, social and environmental components of QoL. Marital status was found to impact the quality of life significantly with single students having a greater QoL. These findings can help form targeted interventions to enhance medical students’ quality of life to prepare efficient future healthcare professionals.
Dufulin activates OsDUF6 protein against salt stress in rice plant
Authors: Ma Guangming , zhang Yong , Li Xiangyang Y. 
Published: January 2024

Abstract
Background
Dufulin is a chemical immune activator in rice plant. Soil salinity is one of the main environmental stresses in rice production. When plants are exposed to salt stress, a range of cellular equilibria will be disrupted. Previous studies have shown that Dufulin has a positive effect on salt tolerance in rice.
Results
In this study, we studied the mechanism of Dufulin in response to salt stress. Based on the transcriptome analysis of Dufulin in the process of salt tolerance in rice, we selected the OsDUF6 protein located on the cell membrane and studied its molecular function by overexpression of OsDUF6. The results showed that the salt-induced decreases in root, stem, and leaf length and increased leaf yellowing rate and Na+ concentration in the wild-type plant were improved in the overexpressed lines, and increased the enzyme activity of the SOD, POD, CAT and PAL. OsDUF6 played a positive role in Na + transport by comparing the growth of the salt-sensitive yeast mutant complemented with OsDUF6. In addition, RT-qPCR analysis confirmed that the overexpression of OsDUF6 significantly changed the expression level of genes related to growth and stress tolerance.
Conclusions
Combined with previously published data, our results supported that OsDUF6 is an important functional factor of Dufulin to promote salt stress resistance in rice and plays a role in promoting salt tolerance in rice.
