Standardizing Free-Text Data Exemplified by Age and Data-Location Fields in the Immune Epitope Database
Authors: Duesing Sebastian , Bennett Jason , Overton James A. , Vita Randi , Peters Bjoern
Published: November 2024

Background
While unstructured data, such as free text, constitutes a large amount of publicly available biomedical data, it is underutilized in automated analyses due to the difficulty of extracting meaning from it. Normalizing free-text data, i.e., removing inessential variance, enables the use of structured vocabularies like ontologies to represent the data and allow for harmonized queries over it. This paper presents an adaptable tool for free-text normalization and an evaluation of the application of this tool to two different sets of unstructured biomedical data curated from the literature in the Immune Epitope Database (IEDB): age and data-location.
Results
Free text entries for the database fields for subject age (4095 distinct values) and publication data-location (251,810 distinct values) in the IEDB were analyzed. Normalization was performed in three steps, namely character normalization, word normalization, and phrase normalization, using generalizable rules developed and applied with the tool presented in this manuscript. For the age dataset, in the character stage, the application of 21 rules resulted in 99.97% output validity; in the word stage, the application of 94 rules resulted in 98.06% output validity; and in the phrase stage, the application of 16 rules resulted in 83.81% output validity. For the data-location dataset, in the character stage, the application of 39 rules resulted in 99.99% output validity; in the word stage, the application of 187 rules resulted in 98.46% output validity; and in the phrase stage, the application of 12 rules resulted in 97.95% output validity.
Conclusions
We developed a generalizable approach for normalization of free text as found in database fields with content on a specific topic. Creating and testing the rules took a one-time effort for a given field that can now be applied to data as it is being curated. The standardization achieved in two datasets tested produces significantly reduced variance in the content which enhances the findability and usability of that data, chiefly by improving search functionality and enabling linkages with formal ontologies.
Unveiling the Hidden Link: Stomach Disease as a Risk Factor for Knee Osteoarthritis
Authors: Yang Xing , Yang Xi , Li Ping , Liu Hong
Published: November 2024

Background
The knee joint is one of the most frequently affected joints in osteoarthritis (OA). However, the specific connection between gastric diseases and the occurrence of knee osteoarthritis (KOA) is currently unclear. The objective of this study is to explore the potential association between gastric diseases and KOA using the China Health and Retirement Longitudinal Study (CHARLS) database.
Methods
A total of 1053 subjects with complete information in 2018 from CHARLS database were included. First, the baseline characteristics of these subjects (covariates such as gender, residence, and smoke) were compared. Then, the relationship between stomach diseases and KOA was explored through 3 weighted multivariate logistic regression models. Afterwards, risk stratification analyses were taken to further confirm the stability of the correlation between stomach disease and KOA risk in different populations. The receiver operating characteristic (ROC) curve of model 3 was plotted to verify the predictive efficiency of stomach disease in KOA risk.
Results
we divided the subjects into 2 groups: the KOA group (n = 71) and the control group (n = 982). The baseline characteristics table revealed that substantial differences in heart attack, kidney illness, stomach disease, as well as health status between the KOA and control groups. Model 1 had an odds ratio (OR) of 3.05 (95% confidence interval (CI) = 1.75–5.30, P < 0.001). After adjusting for location, gender, and smoke, model 2's OR was 3.02 (95% CI = 1.73–5.28, P < 0.001), while model 3's OR was 2.48 (95% CI = 1.37–4.47, P = 0.002). The 3 models demonstrated that stomach disease and KOA were significantly associated and stomach disease was a risk factor for KOA, and the other covariates did not change the relationship. Risk stratification analyses indicated a stable association between stomach disease and KOA risk across populations. The area under the curve (AUC) was 0.722, indicating that model 3 had a good predictive accuracy.
Conclusion
In this study, we furtherly explored the correlation between stomach disease and KOA, and certified that stomach disease was a risk factor for KOA, which provided a reference for the correlation analysis between them.

Published: November 2024

Simulation and simulation-assisted methods have a large impact for product development in many industrial fields. Multibody dynamics (MBD) simulation, for instance, is an established method used for durability analysis and energy efficiency calculations in vehicle engineering, based on its ability to provide accurate prediction of interaction forces. In the domain of off-road vehicles and heavy machinery, such considerations need to be expanded by a method to model the soil and its interaction with the vehicle, i.e., the soil-tool interaction, as the resulting forces may drastically influence the durability and energy efficiency of the machine. Therefore, the model must be chosen carefully to maintain the high accuracy in the force prediction for the soil-tool interaction, as required for a reliable and robust product development.
In this contribution, we present a workflow to tackle this topic, based on a co-simulation scheme between an MBD-based vehicle model and a particle simulation realized in the Discrete Element Method (DEM). The simulated soil is parametrized and validated by matching simulation results from a virtual experiment with measurement data from real-world soil laboratory experiments as the triaxial compression test. Using this process, the applicability and performance of the numerical methods can be determined.

Published: November 2024

A fundamental question in oral science is elucidating the factors that underpin the distinct tissue characteristics of human keratinized and non-keratinized mucosa. Clinical autotransplantation and large animal studies have observed that intrinsic regulation within connective tissue defines mucosal phenotypes, emphasizing the need for in-depth molecular characterization, which remains largely unexplored. This study aimed to map the molecular blueprints of in situ connective tissues and isolated fibroblasts of human keratinized oral mucosa (gingiva, GIN) and non-keratinized oral mucosa (alveolar mucosa, ALV). Distinct variations were observed in extracellular matrix composition, retinoic acid metabolism (closely associated with keratinization), and immune function between GIN and ALV. GIN displayed higher expression of collagen-related genes (notably COL1 and COL3) and lower expression of elastin-related genes. In GIN, the retinol metabolism pathway was enriched, with downregulation of retinoic acid synthesis and upregulation of its catabolism. In contrast, the complement and coagulation cascade were notably upregulated in ALV, with significantly elevated expression of C3. This study is the first to systematically dissect and compare the molecular profiles of connective tissue in GIN and ALV providing foundational insights that could drive future advancements in mucosal phenotype modulation and regenerative therapies.

Published: November 2024

The proposed work described a new Multiple Delay Signal Cancellation (MDSC) control technique for power quality improvement including harmonic cancellation and power factor improvement for a three-phase self-excited induction generator (SEIG)-Distributed Static Compensator (DSTATCOM) based system. A detailed design and stability analysis is being carried out. The MDSC possesses multiple variable length delay signals so as to extract the positive and the negative sequence components (PSC and NSC) so as to generate sinusoidal reference currents for the source. An extensive simulation analysis is being executed to illustrate the controller's efficiency using MATLAB/SIMULINK. A hardware prototype is being developed in the laboratory including SEIG and DSTATCOM. The hardware results prove the effectiveness of the proposed control filter.
Integrated organic geochemical and palynological study of Eocene Kopili Shale in North Cachar Hills, Assam, India: Source rock potential, depositional environment and paleoclimate implications

Published: November 2024

We conducted this first-ever integrated organic geochemical and palynological study of the Kopili Shale (KS) in North Cachar Hills (NCHs) of Assam, India, aiming to assess its source rock potential, depositional environment and palaeoclimate conditions. Organic geochemical study reveals that majority of the samples exhibit low total organic carbon content (TOC) (0.11–1.83 wt. %; average: 0.5%), implying poor hydrocarbon source potential. S1 (0.01–0.11 mg HC/g rock; average: 0.03 mg HC/g rock) and S2 (0.04–3.51 mg HC/g rock; average: 0.36 mg HC/g rock) contents are poor, which indicate poor source rock quality. Low Genetic potential (GP) values (0.05–3.62 mg HC/g, average: 0.39 mg HC/g) suggest poor, gas/non generative source rock. The samples contain terrigenous organic matter (OM) with predominant type III (gas-prone) and IV (inert) kerogen, hence are expected to produce gas, or the kerogens are inert or thermally overmature. Tmax values (370–471°C) imply thermally immature to post-mature source rock. Our current organic geochemical study divulges that the KS in the NCHs has poor source rock potential for producing hydrocarbon. Regionally, the source rock potential of the KS in the NCHs aligns with those found in the contiguous surface regions, the Shillong Plateau (SP), Meghalaya, and in Bengal Basin (BB), Bangladesh. Conversely, KS in the subcrops of the Upper Assam Shelf (UAS) has fair to good potential for producing hydrocarbon. Comprehensive palynological study discloses that the KS in the NCHs, adjacent areas, sub crops of UAS, SP, and BB was deposited in a shallow marine environment (SME) under suboxic - anoxic basin (SAB) conditions. The paleoclimate during deposition of the KS was tropical - subtropical (TST) with warm - humid (WH) palaeoclimatic condition. This pioneering investigation can guide future exploration in larger areas including contiguous surface as well as subsurface regions. This analysis is crucial for companies in the energy sector to optimize extraction techniques and manage resources efficiently.

Published: November 2024

Introduction: Kidney cancer is an immunogenic tumor and inflammation plays a role in tumor formation and progression. The aim of this study was to investigate the effect of biochemical markers in predicting treatment response in patients with metastatic renal cell carcinoma (RCC) receiving nivolumab treatment.
Method: Patients aged ≥18 years who received nivolumab treatment for metastatic RCC between February 2022 and January 2024 were evaluated. Cellular blood count was evaluated at the diagnosis of metastatic disease and periodically during nivolumab treatment. We measured the cell count in peripheral blood at admission and calculated the inflammation indices obtained from the blood cell count as follows: MCVL (mean corpuscular volume/lymphocytes) and IIC ((mean corpuscular volume * width of erythrocyte distribution * neutrophils / (lymphocytes*1000)).
Results: The study included 99 patients. The mean age of the patients was 58.32±11.95 (19-87). 75.8% of the patients had clear cell and 8.1% had papillary type pathology. When the disease control status was evaluated at 3 months after nivolumab treatment, it was seen that 48 patients had partial response and 18 patients remained stable. The 3rd month disease control rate (DCR) was 68.7%. When the ICIC and MCVL rates of the patients were examined, it was determined that the ICC and MCVL values of the patients who showed progression were higher (p=0.038 for ICC, p=0.040 for MCVL). The ICC cutoff value was determined as 15.50. With this cutoff value, disease control can be predicted with 77% sensitivity and 64% specificity (AUC: 0.743 CI 95% [0.647-0.838]; p<0.001). MCVL cutoff value was determined as 65.15. This cutoff value can predict disease control with 65% sensitivity and 61% specificity (AUC: 0.674, CI95% [0.564-0.783], p=0.006).
Conclusion: ICC and MCVL have a significant effect on disease-free survival and overall survival in predicting success of nivolumab treatment for metastatic renal cell carcinoma.

AN INTERNAL STRUCTURE OF THE CHEMISTRY FIELD IN BRAZIL. This article investigates the configuration of the internal structure of the field of chemistry in Brazil, with an emphasis on the positions occupied by dominant and dominated agents. Utilizing the theoretical framework by Pierre Bourdieu, specifically his approach to fields of power and capital, the study proposes a detailed analysis of the distribution of specific capital among Brazilian chemists. The research was divided into two main methodological stages: firstly, configuring the field through the localization of agents in the academic space based on their volume of specific capital; secondly, an analysis focused on the agents occupying the extreme positions in this space, identified as dominants and dominated. This type of analysis contributes to understanding the field, its values and how its power structure is distributed. This information helps agents to understand and move within this configuration with a view to its conservation or subversion.

Knowledge, Attitudes and Practices Related to Viral Hepatitis Among Professionals in a Brazilian Health Foundation
Authors: Scarponi Cristiane Faria Oliveira , Souza-Silva Gabriel , Mol Marcos Paulo Gomes
Published: November 2024

Awareness of viral hepatitis is a key factor in the suppression of this health condition, particularly among healthcare professionals. This study aimed to evaluate the level of knowledge, attitudes, and practices related to viral hepatitis in a Brazilian public health foundation. A self-administered questionnaire, addressing was electronically available to all professionals in December 2020. Descriptive and inferential analyses were performed using OpenEpi software. The response rate of the viral hepatitis questionnaire was 99.2%. The accuracy index for knowledge was less than 70%, encompassing basic concepts, modes of transmission, and vaccination. Most professionals reported accurate preventive attitudes, except for the decontamination of work surfaces, hygiene, and cooking of food. A high rate of unsafe actions was identified, such as engaging in unprotected sex, sharing personal objects when caring for nails, incomplete use of personal protective equipment, and incomplete vaccination. There is a general lack of awareness regarding viral hepatitis, especially among healthcare professionals. The poor understanding of risks and prevention methods has led many professionals to act imprudently or negligently. These findings provide concrete subsidies for the formulation of more effective educational actions and institutional training, given that the mere provision of information does not produce effective changes in professional behavior.

Published: November 2024

The venom of social wasps can be a natural promising product for the development of drugs, since in recent decades studies have investigated its antimicrobial potential, anti-inflammatory, antioxidant, anticarcinogenic, among others for its future applicability in the pharmacological industry. Although some studies have already highlighted the importance of venom for this role, few species of social wasps have had the potential of their venom investigation. In this sense, the aim of this study was to evaluate the cytotoxicity, mutagenicity and cell viability of Polybia sericea (Oliver) venom. Cytotoxicity tests using Artemia salina, cell viability test using non-tumor and tumor cell lines and Ames test that assesses genetic and cellular instability were performed. The results show that the venom presents cytotoxicity, with LD50 of 22.1 μg mL-1. Mutagenicity was not identified in the Ames test at the concentrations studied. The venom did not present cytotoxicity for MRC-5 cell line, but was cytotoxic for CHO and tumor cell line B16F10-Nex2. Therefore, these tests show that P. sericea venom may have potential for pharmacological use, although other studies of cytotoxicity and with more tumor cell lines need to be developed.
Ad majorem Dei gloriam. A contribution to education and formation by the Jesuit College in Płock in the 17th and 18th centuries
Authors: Graczyk Waldemar
Published: November 2024

Bishop Marcin Szyszkowski of Płock (1607-1616) founded the Jesuit College in his diocesan capital in 1611, later approved by the Sejm of the Polish-Lithuanian Commonwealth in 1616. The founder granted the Jesuits the house previously occupied by the collegiate school of St. Michael’s. The arrival of the Jesuits and the establishment of the school were met with great approval from the local nobility. The activities of the College in the years 1611 -1773 contributed significantly to the elevation of education in Mazovia, particularly in Płock, during the early modern period as well as the improvement of life, especially in terms of religion and culture. Thanks to those who taught rhetoric “for the greater glory of God,” who died in the service to the infected, who wrote theatrical plays, preached fervent sermons, and led the Sodality, a solid foundation was laid for the construction of a society conscious of its roots and responsible for the welfare of the Commonwealth.

Regestry podróżne, chociaż pojawiają się często w źródłach tej epoki, nie cieszą się zbyt wielką popularnością wśród badaczy ze względu na monotonię notatek i brak szerszych odniesień czy ciekawych opisów, które można spożytkować w opracowaniu nowożytnych podróży. Tymczasem stanowią one interesujące źródło do badań nad życiem codziennym dworów szlacheckich w dawnej Rzeczypospolitej. Niewiele wiadomo o podróżach handlowych, podejmowanych w interesach czy w celach innych niż turystyczne bądź edukacyjne, tymczasem regestry drogi przynoszą wiele cennych informacji o kosztach podróży, jej organizacji i aprowizacji czy bezpieczeństwie podróżujących.
Historia świecka i/a sakralna? Problem systematyzacji wiedzy o przeszłości w wybranych słownikach i encyklopediach długiego wieku osiemnastego
Authors: Orzeł Joanna
Published: November 2024

W długim wieku XVIII wśród uczonych modne było tworzenie dzieł encyklopedycznych mających popularyzować wiedzę. We francuskich, brytyjskich czy polskich słownikach i encyklopediach ich twórcy odnosili się do przeszłości: zarówno tej dotyczącej sacrum, jak i profanum. Kończono ze ślepym uwielbieniem dla tradycji i podkreślano potrzebę bardziej krytycznego podejścia do dzieł historycznych, ale i źródeł, w tym Pisma Świętego. Coraz częściej głównie francuscy filozofowie, a w ślad za nimi polscy uczeni, przestali włączać historię sakralną w skład pojęcia „historia”, tłumacząc to ostatnie jako opis dziejów ludzkości, oparty na rozumie, a nie wierze.
Giovanni Della Casa i jego An uxor sit ducenda jako przykład szesnastowiecznej literatury mizoginicznej i mizogamicznej
Authors: Misztal Mariusz
Published: November 2024

Giovanni Della Casa (1505-1556), arcybiskup i papieski dyplomata, był autorem łacińskiego traktatu znanego pod tytułem An uxor sit ducenda, który powszechnie uważany jest za niezaprzeczalny dowód na zajadłą mizoginię Della Casy. Obecna analiza utworu, oparta na najnowszych badaniach, proponuje przynajmniej częściową obronę Della Casy przed tą nie do końca sprawiedliwą opinią. Mizoginia Della Casy to często produkt uboczny jego mizogamii. Traktat opisuje trudną, zarówno dla mężczyzn, jak i kobiet, rzeczywistość życia w aranżowanym przez rodzinę związku oraz krytykuje zasady i konwenanse dotyczące zawierania małżeństw wśród wyższych warstw społecznych. Utwór ten był, być może, symbolicznym pożegnaniem ze świeckim życiem przed wstąpieniem na drogę kariery w Kościele.

Anticipating Place in the Emergent Darkness of the Urban Night
Authors: Downey Claire
Published: November 2024

This paper explores the unfulfilled spatial potential of the darkening urban nightscape. And more specifically, how critical concepts of possibility might provide urban theorists access to a night that has yet to take form. In doing so, I build on the presumption that global movements to decrease energy consumption and light pollution will lead to a reduction in nighttime uses of artificial illumination. And that as cities transition to sober lighting technologies, nocturnal darkness can take a more active role in shaping urban space. To what extent this transition will be deployed, in what forms and with what outcomes, are open questions. The urban night remains a space and time of possibility. Its situation is fluid, and its parameters not yet fully drawn. In this state, I suggest that the darkening night lends itself to ontological considerations of what Ernst Bloch termed the anticipatory, or an analysis of what is both in process and on the way. It is an analysis that is firmly situated in the realities of the present urban night, while encouraging the projection of alternate imaginaries for a more sustainable future. Through the analysis of possibility, we can anticipate new ways of composing, and being in, nocturnal urban space.

Authors: Garcia-Ruiz Manuel
Published: November 2024

This paper explores the significance of urban light festivals and their role in contributing to transnational identities and narratives through a detailed study of the Mi-e Dor De Tine project. This public art project serves as an example of how light-based installations shape transnational affective experiences, particularly within the Romanian diaspora across various locations around the world. Through an ethnographic and netnographic study conducted from 2018 to 2024, this research critically engages with Mi-e Dor De Tine project within the frameworks of aesthetic capitalism, affect theory, and transnationalism. The paper emphasizes that urban light festivals not only serve as tools for urban regeneration and cultural diplomacy but also play a vital role in affirming and developing complex urban identities and affective experiences.

Published: November 2024

Learning continuously evolves, propelled by advancements in science and technology as well as the shifting needs and preferences of students. A critical question arises: Are prospective teachers adequately prepared to adapt to these evolving demands with the necessary competencies? This study addresses this question by investigating the effectiveness of an Integrated Learning Model (ILM) in enhancing key teaching competencies. The research focuses on teaching skills, analytical thinking abilities, academic integrity, and transformational leadership qualities among prospective teachers. The study employs an experimental research design, utilizing a one-group pre-test-post-test methodology to assess the impact of the ILM on 35 students selected through cluster sampling. Data collection instruments included the TPOG for evaluating teaching skills, the ATSI for assessing analytical thinking, the PAAIS-24 for measuring academic integrity, and the GTLS for gauging transformational leadership abilities. The data analysis involved descriptive statistics, paired samples t-tests, and N-gain score analysis. The results indicate a significant positive effect of the ILM on all measured competencies: teaching skills, analytical thinking skills, academic integrity, and transformational leadership. These findings underscore the ILM's potential as a robust framework for developing the competencies necessary for prospective teachers to meet the challenges of modern education. The study suggests that future research should explore the application of ILM in various social contexts, examine its effectiveness in fostering additional relevant competencies, and compare its outcomes with those of other instructional models. Such investigations will contribute to a deeper understanding of ILM's role in preparing teachers for the demands of 21st-century education.

Published: November 2024

Social support plays a crucial role in an individual's life. Individuals who experience strong, positive social relationships and feel supported by others tend to report lower levels of anxiety, depression, and psychological stress. Social support may come from family members, friends, and significant others in life. Looking at the importance of social support in university students’ lives, there have been a few scales to measure social support, and one of them is the Multidimensional Perceived Social Support Scale, which was developed in a Western country. This study examined the validity of the Malay version of the Multidimensional Perceived Social Support Scale in a sample of 443 Malaysian university students. Results support the high reliability and validity of this scale. Confirmatory factor analysis reported the expected three-factor structure and a high correlation between factors and scales. In addition, internal consistency was good, and correlation analysis with the Satisfaction with Life Scale proved the theoretical relations among the constructs. The findings suggest that MPSS-M is a reliable and valid tool to measure social support among students in higher education institutions. Campus leaders and student affairs professionals may use the scale to identify the source of support among students. Implication for university management is also discussed.

Published: November 2024

This study aims to examine the effect of the application of two different learning models (Sport Education and Traditional Teaching) by pre-service teachers on the empowerment and self-confidence of students in physical education classes at secondary schools. The research design used was a quasi-experimental pretest-posttest. The research sample was 429 high school students involving 8 schools in Jakarta, Indonesia. The sample consisted of 220 girls and 209 boys aged between 15 to 18 years old. The instruments used were the Psychological Empowerment Instrument and the Competitive State Anxiety Inventory-2 (CSAI-2). The results show that the Sport Education learning model can significantly increase student’s self-confidence and empowerment, while in the Traditional Teaching model student’s self-confidence and empowerment did not have a significant increase. The results of this study prove that the Sport Education model is better than the Traditional Teaching model.

Published: November 2024

Mathematical literacy assumes a significant role in assisting students in resolving everyday problems. The research design utilized in this study is a descriptive qualitative method, which aims to assess students' literacy skills by categorizing them as high, moderate, or low based on various mathematical literacy indicators on the spatial facets of geometry. Research results were analyzed and sorted into categories denoting high, moderate, and low mathematical abilities, with one research subject chosen from each category from a total of 32 students. The outcomes reveal that students with high mathematical test abilities could formulate and apply appropriate formulas, interpret and effectively communicate results, and draw accurate conclusions. Students with moderate abilities were only formulating and interpreting while needing more ability to effectively communicate, provide suitable conclusions, or evaluate the problems encountered. Lastly, the low ones needed help to solve the given problems and indicators.

Published: November 2024

This study investigates tutor-student interaction patterns in online learning environments, aiming to unveil effective strategies for optimising the online educational experience. Guided by a qualitative approach employing a case study design, this study delves into the interaction and written communication dynamics among 65 students and their tutors participating in four-course programs within the biology education study program. The observational and analytical phases focused on unravelling the nuances of online interactions. Subsequently, follow-up interviews were conducted to glean deeper insights and understanding into the observed patterns of communication and engagement between students and tutors. Through the qualitative analysis procedure, five distinct interaction patterns emerged from the analysis, ranging from tutor-initiated questions to collaborative exchanges among students and tutors. Each pattern offers unique insights into fostering engagement, feedback, and peer-to-peer learning dynamics.

This study examines the commitment of vocational teacher education students at Universitas Negeri Yogyakarta, Indonesia, and Universiti Tun Hussein Onn Malaysia (UTHM) in applying core character values. The global trend in teacher education links education and economic growth, emphasizing students' competence for the job market. However, teachers are also expected to address social and moral cohesion in the younger generation. The research involved 177 third- and fourth-year students at FPTV UTHM Malaysia and an equal number at FT-UNY, utilizing a questionnaire based on core character values. The findings indicate moderate commitment levels (58.75%) among university students. UTHM students scored slightly higher (2.42) than UNY students (2.28). The study shows that character education for vocational teacher education students in both Indonesia and Malaysia has not reached optimal levels, emphasizing the need to investigate more effective character education models for future vocational teachers.

The study aims to identify challenges teachers and students face in this process at an Islamic bilingual middle boarding school in Aceh, Indonesia. The participants included 27 boarding school students, one English teacher, and one Arabic teacher. The collected data underwent analysis using the interactive analysis model, which involves data reduction, display, and verification. The analysis focuses on specific activities within five categories: (1) mufradat (vocabulary), (2) controlling language use, (3) muhadasah (conversational activities), (4) competition, and (5) cooperation. The findings revealed that not all specified activities were consistently carried out, with each category featuring three implemented activities: daily vocabulary memorization, language festivals, and the application of punishments. The interviews brought forth challenges such as teachers’ language proficiency limitations, students’ low motivation, and a tendency to use the Indonesian language when unsupervised. These insights provide valuable guidance for similar boarding institutions that implement comparable language programs.

Psychological conditions such as stress, anxiety, and depression can trigger sleep bruxism, a parafunctional activity. Dental students are one group that may experience psychological difficulties. Study workloads for dental students can cause stress and lead to sleep bruxism. This research aimed to identify the incidence of sleep bruxism among dental students. Participants were dental students of Universitas Muhammadiyah Yogyakarta (n = 200) aged 23–29 years, with 1–5 years of study periods. We adapted a questionnaire from the American Academy of Sleep Medicine to detect sleep bruxism. This questionnaire contains eight questions about the signs and symptoms experienced by respondents with sleep bruxism. The result of this study showed that only 18% of the participants had sleep bruxism. It can be concluded that the incidence of sleep bruxism in dental students is relatively low.

Complications during root canal therapy, such as perforation, might lead to failure of root canal therapy. A root perforation allows the root canal system and periradicular tissue to communicate, which may affect the treatment outcome. The ability of perforated sealing materials to stop microleakage is also crucial to the success of the treatment. The latest bioactive materials, such as bioactive calcium silicate cement (BCSC) and enhanced resin-modified glass ionomer (ERMGIC), are used. This study compares the microleakage of BCSC and ERMGIC as a material for sealing root perforations at different observation times. Thirty post-extraction premolars, no caries, and single roots were used in this study. Samples were divided into two different groups. The perforation simulation was created using cylindrical fissure round-end burs at a distance of 2 mm from the cervical line. Following the use of BCSC and ERMGIC to seal the perforation, the samples were separated into three subgroups and immersed in a simulated body fluid for different durations in an incubator set at 37°C. As soon as the samples reached the immersion period, all samples were immersed in 1% methylene blue for 24 hours. It was then divided into two parts and examined under a microscope at 50x magnification. The two-way ANOVA test demonstrated no significant variation in the microleakage of the root perforation seal, depending on the material type and the observation time. This study found that microleakage, a material used to seal root perforations, was unaffected by the types of materials used or the length of the observation period.

Titanium is the most widely used dental implant material, but it requires surface treatment to improve osseointegration. While coating implants with TiO2, residue can arise, which may lead to contamination. To address this, 10% HF etching is added. This study investigated the effect of TiO2 coating using sputtering and HF etching on platelet activation in titanium dental implants. Laboratory experiments were conducted on titanium implants (Ø = 4 mm; length = 12 mm) treated with TiO2 coating and 10% HF etching. Twenty-four samples were divided into four groups (n = 6): Group I (TiO2), Group II (TiO2 + HF 5 min), Group III (TiO2 + HF 10 min), and Group IV (TiO2 + HF 20 min). Platelet activation was assessed using CD41 and CD62P expression markers. Data analysis employed one-way ANOVA and post hoc LSD test (p = 0.05). Platelet activation ranged from 20.31 ± 1.78% to 35.90 ± 3.81%. One-way ANOVA revealed a significant effect (p < 0.05) of both TiO2 coating and acid etching on activation. LSD post hoc test showed significant differences (p < 0.05) between all groups except for the 10 and 20-minute etching periods. TiO2 coating with 10 minutes of HF etching resulted in the optimal activation level.

The most recent development in composite resin is bioactive resin, which replaces common resin. If ignored, the tendency for shrinking in bioactive composite resin could result in microleakage. Bonding material innovations that incorporate more filler have also been created to reduce this issue and lower the possibility of microleakage. The purpose of this study is to compare the microleakage of bioactive composite resin restorations with and without filled bonding material. Thirty-two maxillary first premolar samples were split into two groups: group A containing 16 samples repaired with unfilled OptiBondTM Universal (Kerr) and group B containing 16 samples restored with filled SingleBond Universal (3 M). Utilizing ACTIVATM BioACTIVE-Restorative (Pulpdent), the samples from both groups were restored.The specimens were subjected to a 24-hour artificial saliva incubation period, succeeded by an equivalent duration of exposure to 2% methylene blue. A USB digital microscope stereo was used to measure the microleakage by observing the methylene blue 2% penetration depth. Microleakage was 8.95% in group A and 8.83% in group B, according to the results. The findings of the the parametric test using the independent t-test showed that there was no significant difference (p > 0.05) in microleakage across the bioactive composite resin restoration groups. This indicates that the microlekeage of bioactive composite resin restoration is unaffected by the presence of filler in the bonding agent.
