EFFECTS OF THE COMBINATION OF PROPOLIS AND HYDROXYAPATITE ON BONE REGENERATION (AN EXPERIMENTAL ANIMAL STUDY)

INTRODUCTION: The surgeon is always working to replace lost bone and obtaining enough bone quantities to do his/her surgical operations. In the present study we examined propolis in order to determine the bone healing capacity of it. OBJECTIVES: Comparing histologically & histomorphometrically the bone healing rate of the combination of hydroxyapatite plus propolis extract versus hydroxyapatite. METHODOLOGY: Eighteen New Zealand white male rabbits were used. Bilateral designed critical-size bone defects were prepared in the right and left tibia of 12 Rabbits . Defect in the right tibia (positive control) & received hydroxyapatite, while defect in the left tibia (study) & received (hydroxyapatite + propolis). Bilateral critical-size bone defects were prepared in both tibia of the other 6 Rabbits (negative control) & left empty. Sacrificing were done at 3, 6 weeks postoperatively. RESULTS: In the positive control group, at 3 weeks, specimens revealed formation of new bone covering the defect area. While, in the study group, bone consisted of thicker trabeculae with more regularly arranged osteocytes and relatively smaller bone marrow spaces. At 6 weeks, specimens revealed higher percentage of the formed bone in the defect area in both groups. However, in the negative control group, the regenerated bone was lower than in the other groups. Histomorphometrically, the mean percentage of bone surface area in study group was higher than positive control group through all experimental periods but the difference was statistically non-significant (P 3 = 0.155, 0.136) respectively. CONCLUSION: Study revealed that histologically HA plus propolis showed better convenient results.
Seroprevalence and Associated Factors of HBV and HCV among Pregnant Women Attending Antenatal Care at Debre Tabor Comprehensive Specialized Hospital, Northwest Ethiopia: A Cross-Sectional Study

Background Infections with the hepatitis B virus (HBV) and the hepatitis C virus (HCV) are worldwide problems that particularly place a heavy burden on developing nations. HBV and HCV infections during pregnancy have a high rate of vertical transmission and harmful consequences for both the mother and the child. Therefore, this study was carried out to assess the seroprevalence and associated factors of HBV and HCV infections among pregnant women attending antenatal care at Debre Tabor Comprehensive Specialized Hospital in Ethiopia. Methods A cross-sectional study was conducted from March 15th to September 16th, 2022, at the Debre Tabor Comprehensive Specialized Hospital antenatal care clinic. Five milliliters of venous blood were collected from 422 pregnant women selected using a simple random sampling method. Data on sociodemographic characteristics and risk factors were collected using a prestructured questionnaire. A chi-square test, bivariate, and multivariate analyses were used to evaluate the association between dependent and independent variables. p values less than 0.05 were considered statistically significant. Results The seroprevalence of HBV and HCV infections was found to be 13% and 0.5%, respectively. Undertaking blood transfusion (AOR = 14.2, CI = 5.81–34.526, p = 0.001), tattooing (AOR = 3.99, CI = 1.1–14.36, p = 0.034), and dental therapy (AOR = 4.9, CI = 1.41–17.025, p = 0.012) were significantly associated with HBV infection. Conclusion HBV infection in pregnant women was shown to have a high endemicity (13%) in this investigation, whereas the seroprevalence of HCV infection was low (0.5%). HBV infection was significantly associated with a history of blood transfusions, tattooing, and dental therapy. Screening pregnant women for HBV and HCV infections and providing effective therapy would ensure better outcomes for the newborn. In addition, health education must be used to increase knowledge of screening and modes of transmission.
Psychometric Analysis of the Rapid Eating Assessment for Participants-Short Form to Evaluate Dietary Quality in a Pre-Surgical Bariatric Population

Dietary quality and eating behaviors are essential to evaluating bariatric surgery candidates. The Rapid Eating Assessment for Participants–Short Form (REAP-S) is a previously validated measure of dietary quality suited for use in primary care. This study aimed to evaluate the psychometric properties of the REAP-S in a pre-surgical bariatric population. This study included data from one academic medical center from August 2020 to August 2022. Variables included socio-demographics, the REAP-S, mental health, and assessments of appetitive traits. Statistical methods included Cronbach’s alpha, confirmatory factor analysis (CFA), and multivariable analyses. A total of 587 adult patients were included in this analysis. The mean score for the REAP-S was 28.32 (SD: 4.02), indicative of relatively moderate dietary quality. The internal consistency of the REAP-S was moderate, with a Cronbach’s alpha of 0.65. The three-factor CFA model resulted in a comparative fit index of 0.91. Race (p = 0.01), body mass index (p = 0.01), food fussiness (p < 0.0001), food responsiveness (p = 0.005), and socially desirable responses (p = 0.003) were significantly associated with the total REAP-S score. Although the REAP-S’s original purpose was to assess dietary quality within a primary care population, it shows promise for application within a bariatric surgery-seeking population.
THE ROLE OF QUALITY OF WORK-LIFE AS MEDIATOR IN EFFECT OF PSYCHOLOGICAL CAPITAL ON WORK ENGAGEMENT AMONG EMPLOYEES IN COMPANY X IN BATAM, INDONESIA

Today workforces encounter challenging situations. Experts and leaders stated that we currently live in a volatile, unstructured, complex, and ambiguous (VUCA) environment. Moreover, external factors outside organizational circumstances including psychological and emotional state might influence work engagement. However, PsyCap was found to buffered and combat these negative reactions in the workplace. Quality of Work Life (QWL) was also found to be affecting work engagement. Therefore, this study aimed to explore the role of QWL among the effects between PsyCap and work engagement among employees in Company X in Batam, Indonesia. This cross-sectional study used a quantitative design and obtained the data using questionnaires. The data was analyzed using PROCESS Version 4.1. by Hayes (2020) in SPSS Version 25.0. The result shows PsyCap and QWL effects work engagement positively. Moreover, PsyCap was also found to positively effects QWL. Lastly, the result also shows that QWL partially mediated the effect between PsyCap and work engagement.
Correlative study on retinal microvascular changes and sex hormones in male patients with central serous chorioretinopathy

Central serous chorioretinopathy (CSC) is a disease in which the outer retinal barrier is damaged with high incidence in young adult males. We aimed to analyze the correlations between retinal microvascular changes and sex hormone levels. The vascular density of the superficial retinal capillary plexus (SCP), deep retinal capillary plexus (DCP), foveal avascular zone (FAZ) area, choriocapillary blood flow area, and the subfoveal choroidal thickness (SCT) were investigated by optical coherence tomography angiography (OCTA). We also determined the levels of sex hormones (adrenaline (AD), norepinephrine (NE), dopamine (DA), corticosteroids (Cor), aldosterone (ALD), estradiol (E2) and total testosterone (TT)). The relationship between sex hormone levels and OCTA parameters was then determined. We detected significantly higher levels of NE, Cor and TT in serum from the observation group than in the control group (p < 0.05). Significant correlations were identified between SCT and choriocapillary blood flow area in the affected eyes, contralateral eyes and healthy eyes in the control group (p < 0.05). SCT levels of both eyes in the observation group were higher and the choriocapillary blood flow area was smaller than in the control group. The SCT in affected eyes from the observation group were higher than the contralateral eyes (p < 0.05). The choriocapillary blood flow area was significantly smaller than in the contralateral eyes (p < 0.05). Correlation analysis unveiled that NE, Cor and TT levels were positively correlated with SCT in CSC patients and negatively correlated with choriocapillary blood flow area (p < 0.05). The serum levels of sex hormone levels in male CSC patients were different from those in healthy men of the same age. Our findings suggest that the serum levels of NE, Cor and TT levels may influence the pathogenesis of CSC by affecting SCT thickness and choriocapillary blood flow.
Mental health literacy of Chinese nurses from public general and psychiatric hospitals: a cross-sectional study

Background Mental health literacy (MHL) is crucial to address issues related to mental illness. Nurses’ MHL is even more important because they are expected to deal with both the physical and psychological consequences of mental disorders. Objective This study investigated the level, discrepancy, and characteristics of MHL among Chinese nurses from both public general and psychiatric hospitals; identified influential factors; and explored the relationship between MHL and mental health status. Methods Using a stratified cluster sampling method to select participants, a cross-sectional survey was conducted to describe the MHL of 777 nurses from 13 general and 12 psychiatric hospitals using the Chinese version of the Mental Health Literacy Scale, Patient Health Questionnaire-2, Generalized Anxiety Disorder-2, and a demographic questionnaire. A multiple regression analysis was used to determine the factors influencing MHL among the nurses recruited. Results The participants’ total score on the Chinese version of the Mental Health Literacy Scale was 93.25 (SD = 10.52). Multiple regression analysis revealed that nurses who worked in psychiatric or higher-level hospitals, with higher professional titles or higher education had higher levels of overall MHL and core MHL, while those working in general hospitals, with shorter work duration, or who were unmarried had higher social acceptance of patients. Nurses’ MHL was closely correlated with their mental health status. Conclusion The overall and core MHL of Chinese nurses were at a moderate level, with social acceptance remaining at a relatively low level. There is an urgent need for MHL promotion programs to improve the MHL of clinical nurses. The focus must be given to overall MHL, especially core MHL, for non-psychiatric nurses to enhance their competence in mental health promotion and identification; more emphasis should be placed on the social acceptance of patients with mental illnesses for psychiatric nurses to improve their provision of professional services. Better MHL would be a formula for improving nurses’ own mental health and their mental health service competence.
Comparative Analysis of Prokaryotic Extracellular Vesicle Proteins and Their Targeting Signals

Prokaryotic extracellular vesicles (EVs) are vesicles that bud from the cell membrane and are secreted by bacteria and archaea. EV cargo in Gram-negative bacteria includes mostly periplasmic and outer membrane proteins. EVs are clinically important as their cargo can include toxins associated with bacterial virulence and toxicity; additionally, they have been proposed as efficient vaccine agents and as the ancestors of the eukaryotic endomembrane system. However, the mechanistic details behind EV cargo selection and release are still poorly understood. In this study, we have performed bioinformatics analysis of published data on EV proteomes from 38 species of bacteria and 4 archaea. Focusing on clusters of orthologous genes (COGs) and using the EggNOG mapper function, we have identified cargo proteins that are commonly found in EVs across species. We discuss the putative role of these prominent proteins in EV biogenesis and function. We also analyzed the published EV proteomes for conserved signal sequences and discuss the potential role of these signal sequences for EV cargo selection.
Environmental Concern: Antecedents of Ecotourism Visit Intention with Time Perspective and Destination Image as Determination Variables

Environmental damage and sustainability become the center of attention along with climate change today. One of the interesting things is the change in behavior in the consumption of products categorized as "green", including in terms of choosing tourism destinations. Environmentally friendly tourism destinations or ecotourism is increasingly becoming an option for those who care about the environment. Ecotourism is also used by many countries, including travel agents, to increase their economic value or profit. This study aims to investigate how the role of Environmental Concern as antecendent of Ecoturism Visit Intention mediates the influence of Future Time perspective and Destination Image toward Ecotourism visit Intention. This research involved 200 respondents who had visited ecotourism destinations at least twice, which was obtained using a convenience sample approach. The data were analyzed using Structural Equation Modelling (SEM) which were processed using the SmartPLS 4.0 statistical package. The result shows that Future Time perspective and Destination’s Image positively impact Ecotourism Intention. Future Time perspective and Destination’s Image also influence Ecotourism Intention indirectly through Environmental Concern as the mediating variable. As an implication, the government and travel agents improve service readiness and perception of high-value propositions to develop a better destination image.

Let f be a circle homeomorphism with countably many break points that is, differentiable except in countably many points where the derivatives have a jump. Assuming its rotation number ρ to be irrational, we provide a necessary condition for the absolute continuity of invariant measure with respect to the Lebesgue measure.
An Investigation into the Benefits and Challenges of International Student Exchange Programs: Perspectives from Student Teachers

This study explores the perspectives of student teachers from Can Tho University, Vietnam, on the benefits and challenges of engaging in student exchange programs. Utilizing a quantitative research approach, data was collected through a survey instrument consisting of multiple-choice and Likert-scale questions. The survey examined student teachers' perceptions of various advantages, including access to new knowledge, enhanced teaching skills, and valuable support from foreign partners and mentors. Additionally, it investigated challenges related to language differences, cultural norms, and time management. The findings shed light on the experiences of student teachers in exchange programs and reveal that one of the most significant reasons for their participation was the desire to expand their international networks and foster meaningful connections with students from other countries. These insights provide valuable guidance for educational institutions in developing effective strategies and support systems to optimize the participation and satisfaction of student teachers in these programs.
A local artificial‐boundary condition for simulating transient wave radiation in fluid‐saturated porous media of infinite domains

The dynamic problem of wave propagation in infinite fluid‐saturated porous media is usually solved using the finite element method. Therefore, proper artificial‐boundary conditions are required to be imposed on the truncated boundaries of the dynamic finite‐element model to consider the radiation damping effect of the truncated media. A local artificial‐boundary condition is proposed for the dynamic problems in fluid‐saturated porous media in the u−p formulation. It avoids making the unrealistic assumption of zero permeability that is widely used in the existing artificial‐boundary conditions. Moreover, the proposed method can be implemented easily into finite element or finite difference codes as stress and flow velocity boundary conditions. Numerical results obtained from the finite element model using the proposed artificial boundary indicate that the proposed method is stable for long time and is more accurate than several existing methods.

Synthesis of large monolayer single crystal MoS2 nanosheets with uniform size through a double-tube technology

Two-dimensional MoS2 attracts much attention because of its potential application in electronic and optoelectronic devices at present. However, the preparation of large and uniform single crystal MoS2 nanosheets is still a challenge, which restricts its further application. Herein, monolayer single crystal MoS2 nanosheets with large and uniform grain size have been synthesized by chemical vapor deposition using a double-tube system. Within the main growth area, the grain size reaches 146 μm on the substrate of SiO2/Si, and the portion of MoS2 nanosheets with grain size between 50 μm and 100 μm is up to 78%. Meanwhile, the grain size keeps constant in the direction perpendicular to the tubes and changes slightly in the parallel direction. This is attributed to the concentration distribution of intermediate product MoO3−x in the one-side sealed inner tube set in a quartz tube, i.e., the double-tube system, which provides a way to the controllable and uniform synthesis of large monolayer single crystal MoS2 .
The Treatment of Argument Structure Constructions in Online English Learners' Dictionaries: The Case of V N ADJ ASCs

Despite their diversity and complexity in structure and meaning, little research has been conducted into the systematic presentation of argument structure constructions (ASCs) in English learners' dictionaries (ELDs). To fill in the gap, this paper focused on the treatment of V N ADJ ASCs in the "Big Five" online ELDs against usage data. First a list of 40 target verbs was obtained using two measures of contingency (i.e., faithfulness and collostruction strength) through collo­structional analysis of V N ADJ ASCs in the British National Corpus, and then the related ASCs regarding their macro- and micro-structural presentation in selected dictionaries were examined. It was found that most ELDs attach importance to ASCs, notably LDOCE, which assigns many of them the status of phrases. Nevertheless, the treatment of ASCs in current ELDs is inadequate. First, the inclusion of ASCs in most ELDs is far from sufficient. Second, in some cases, there is a mismatch between a valency pattern illustration and an illustrative example. Last but not least, most ELDs are not consistent with respect to their policy of listing and encoding ASCs, and assigning them the status of phrases. We proposed, in the framework of the usage-based construc­tion grammar, some suggestions for optimizing the treatment of ASCs. Keywords: argument structure constructions, online English learners' dictionary, phraseology, collostructional analysis, usage-based con­struction grammar

Understanding Quiet and Storm Time EMIC Waves—Van Allen Probes Results

Geomagnetic indices have been used as a proxy for studying electromagnetic ion cyclotron (EMIC) wave occurrences under different geomagnetic conditions. However, the drivers of EMIC waves are different during non‐storm, storm time and during individual storm phases. Using ∼7 years of data from the twin Van Allen Probes, we demonstrate that the occurrence probability of EMIC waves are not well captured by a specific geomagnetic activity index alone, but is rather well manifested by considering individual storm phases. We show EMIC wave occurrence statistics during different storm phases (pre‐onset, main and recovery) for geomagnetic activity indices Sym‐H, AE, and Kp and solar wind dynamic pressure Pdyn, illustrating that the occurrence rates vary significantly during different storm phases even for a given geomagnetic index. We also utilize this large database to show EMIC wave occurrence distribution, and how various wave and plasma parameters behave under different geomagnetic conditions. EMIC waves occur 2.9 times more often during geomagnetic storms than during non‐storm times. The majority (72%) of storm time EMIC waves occur during the recovery phase due to long recovering time, while the highest occurrence rates are in the pre‐onset phase, followed by main and recovery phases. EMIC waves in the main phase have occurrence peaks in the dusk to pre‐midnight sectors while recovery phase events spread to more Magnetic Local Time (MLT) sectors with peaks in the morning sector. Wave amplitudes are found to be evenly distributed across different MLT sectors during all geomagnetic conditions.
A Multilayered Magnetoelectric Transmitter with Suppressed Nonlinearity for Portable VLF Communication

Acoustically actuated magnetoelectric (ME) antenna based on the efficient oscillation of magnetic dipoles has recently been considered as a promising solution for portable very-low-frequency communications. However, the severe nonlinear dynamic behavior in the case of strong-field excitation results in insufficient radiation capability and poor communication performance for a conventional ME antenna. In this work, we propose to suppress the nonlinearity of an ME antenna by neutralizing the spring-hardening effect in amorphous Metglas and the spring-softening effect in piezoelectric ceramics through an ME multilayered transmitter (ME-MLTx) design. With a driving voltage of 50 Vpp at the resonance frequency of 21.2 kHz, a magnetic flux density as high as 108 fT at a distance of 100 m is produced from a single ME-MLTx. In addition, ME-MLTx performs a decreased mechanical quality factor (Q m) less than 40.65, and, thus, a broadened bandwidth of 500 Hz is generated. Finally, a communication link transmitting binary American Standard Code for Information Interchange-coded message is built, which allows for an error-free communication with a distance of 18 m and a data rate of 300 bit/s in the presence of heavy environment noise. The communication distance can be further estimated over 100 m when using a femtotesla-class-inductive magnetic field receiver. The obtained results are believed to bring ME antennas one step closer to being applicable in very-low-frequency communications.
