Published: January 2025

Brucellosis remains a critical zoonotic infection with profound implications for public health across diverse regions, including the Middle East, Asia, the Arabian Peninsula, the Mediterranean, Africa, and South and Central American countries. This global threat necessitates ongoing investigation and surveillance. Accordingly, this study aimed to elucidate the presence and characteristics of Brucella spp. isolated from patients in a province of eastern Türkiye. A combination of conventional and molecular techniques was employed to achieve comprehensive species and biovar determination. A total of 189 human Brucella spp. strains isolated from blood cultures at Bitlis State Hospital between 2010 and 2020 were included in the study. Identification tests for the isolates comprised assessing serum requirement for growth, oxidase and urease production, as well as lysis testing with Tbilisi phage and R/C phage. Additional conventional biotyping tests involved evaluating hydrogen sulfide (H2S) production, carbon dioxide (CO2) requirement for growth, and growth in media containing thionin, basic fuchsin, and safranin. Furthermore, agglutination with Brucella A and M type monospecific antisera was performed. The isolates also underwent multiplex PCR, specifically the Bruce–Ladder PCR method, for biotyping. The results demonstrated the predominance of Brucella melitensis strains in human brucellosis cases, as identified by both conventional and molecular methods. Specifically, 185 isolates were classified as B. melitensis biovar 3, with the remaining 5 isolates classified as B. melitensis biovar 1. In conclusion, this distribution underscores the significant role of B. melitensis in the epidemiology of human brucellosis in the region. The current study highlights the efficacy of both conventional and molecular methods in Brucella spp. identification, with particular emphasis on the Bruce–Ladder PCR method’s superiority in terms of rapidity and compatibility with traditional techniques. Continued research and surveillance efforts are imperative to deepen our understanding of the epidemiology and dynamics of this zoonotic disease.

This study was conducted to determine the mohair quality characteristics of Eskisehir, Lalahan and Siirt variety Angora goats. In the study, mohair samples were taken from the shoulder, rump and rib regions of each Angora goat of Eskisehir, Lalahan and Siirt varieties during the mohair shearing period. A total of 57 samples from 19 heads of Angora goats were analyzed in terms of quality characteristics such as clean weight, dirty weight, yield, length, fineness, elasticity and tenacity. According to the results obtained, the effect of variety and gender on the dirty weight, clean weight and yield variables was statistically significant (P<0.05), while the effect of the region was found to be insignificant (P>0.05). The effect of variety and region on the length variable was found to be statistically significant, while the effect of gender was found to be insignificant. The effect of variety and gender on the fineness variable was found to be statistically significant, while the effect of region was found to be statistically insignificant. The effects of variety, gender and region on the elasticity variable were found to be statistically insignificant. The effect of variety on the tenacity variable was found to be statistically significant, while the effect of gender and region was found to be statistically insignificant. According to the information obtained from this study, variety, region and gender variables have various effects on mohair characteristics. It is thought that these characteristics will contribute to studies on breeding Angora goats and improving mohair quality.

Las betalactamasas de espectro extendido (BLEE) son enzimas bacterianas que confieren resistencia a antibióticos betalactámicos, como penicilinas y cefalosporinas de diversas generaciones, a excepción de cefamicinas y carbapenémicos. Estas enzimas pueden ser inhibidas por el ácido clavulánico. Aunque inicialmente se asociaron con Klebsiella pneumoniae, actualmente Escherichia coli es uno de los principales productores de BLEE en ambientes hospitalarios y comunitarios. Las cepas de E. coli productoras de BLEE están clasificadas como patógenos prioritarios por la Organización Mundial de la Salud (OMS) debido a su capacidad de desarrollar resistencia a múltiples antibióticos (MDR). Este fenómeno se debe a la transmisión de genes mediante plásmidos, lo que facilita su diseminación entre humanos y animales. El contacto estrecho entre humanos y perros domésticos es un posible factor de riesgo para la diseminación de estas cepas multirresistentes. A nivel mundial, se estima que alrededor del 6,9 % de los perros son portadores de E. coli productora de BLEE, mientras que en Ecuador, algunos estudios han reportado presencia de E. coli productora de BLEE hasta un 40 % en muestras fecales de caninos. Este estudio se centró en evaluar la prevalencia de cepas de E. coli productoras de BLEE en 114 perros atendidos en la Clínica Veterinaria de la Universidad de Machala. Las muestras se tomaron mediante hisopados rectales y fueron cultivadas en agar cromogénico, lo que permitió identificar 39 cepas de E. coli productoras de BLEE, representando un 34,2 % del total. Las cepas mostraron alta resistencia a monobactámicos, cefalosporinas y tetraciclinas, aunque todas fueron sensibles a carbapenémicos como imipenem y meropenem. Estos hallazgos destacan la necesidad de una mayor vigilancia de la resistencia antimicrobiana en animales domésticos, ya que el uso indiscriminado de antibióticos en medicina veterinaria podría estar contribuyendo a la selección de cepas resistentes, con implicaciones importantes para la salud pública.

Published: January 2025

Stress response of the horse may be related to the behavioral and physiologic factors e.g., stress hormones. The aim of this study was to evaluate the different rider contact on the stress hormones of the horses that are used for javelin sport in a local riding club. Seven Arabian horses were ridden by familiar riders with the horses in the first and second weeks and by additional unfamiliar riders with the horses in the third and fourth weeks. Cortisol, oxytocin and beta–endorphin levels in sera samples and cortisol levels in saliva were measured before and after the riding. There was no statistical difference in serum cortisol and β–endorphin and salivary cortisol values between the groups with regard to the familiarity (P>0.05). Behavioral scoring did not differ between the groups. However, there was an increase in the oxytocin level of the horses ridden by the familiar riders in the second week compared with the first week (P<0.05). The horses did not respond stressfully associated with the hormone levels and behavioral changes; besides, they responded well to the familiar riders by elevating the oxytocin level. In conclusion, the horses used herein responded well to the familiar and unfamiliar riders with regard to potential stress factors. It has been therefore suggested that the familiarity towards the interaction between the human and the horse may not alter the physiological stress of the horses that are regularly ridden by various people in a riding club.

Lipopolysaccharide (LPS), known as a stimulant of inflammation, causes acute liver injury by inducing the production of inflammatory mediators and oxidative stress. The purpose of this study is to determine whether of a nonsteroidal anti–inflammatory drug (NSAID) Flunixin meglumine (FM) and herbal an medicine Ginkgo biloba L. extract (GBE) show antioxidative, anti–inflammatory or antiapoptotic effects in liver tissue in LPS–induced hepatotoxicity. Animals were separated to 6 groups as control, sepsis (1 mg·kg-1, 7th day single dose, intraperitoneal (ip)), sepsis + FM (1 mg·kg-1, 7th day single dose, ip + 2.2 mg·kg-1 day, ip), sepsis + GBE (1 mg·kg-1, 7th day single dose, ip + 50 mg·kg-1 day, gavage), FM and GBE and the study continued for 7 days. Liver tissues taken from rats sacrificed were analyzed biochemically, histologically and immunohistochemically. Accordingly, LPS caused liver function markers alteration, inflammation, oxidative stress, and apoptosis, as well as histopathological changes in liver tissue. However, it was observed that LPS–induced changes were regulated by FM and GBE application. FM and GBE was demonstrated to have antioxidant, antiinflammatory and anti–apoptotic properties in LPS–induced hepatotoxicity.
Local and global stability of a fractional viral infection model with two routes of propagation, cure rate and non-lytic humoral immunity
Authors: Naim Mouhcine , Zeb Anwar , Mohsen Ahmed Ali , Sabbar Yassine , Yıldız Mustafa
Published: January 2025

A fractional viral model is proposed in this work, as fractional-order calculus is considered more suitable than integer-order calculus for modeling virological systems with inherent memory and long-range interactions. The model incorporates virus-to-cell infection, cell-to-cell transmission, cure rate, and humoral immunity. Additionally, the non-lytic immunological mechanism, which prevents viral reproduction and reduces cell infection, is included. Caputo fractional derivatives are utilized in each compartment to capture long-term memory effects and non-local behavior. It is demonstrated that the model has nonnegative and bounded solutions. Three equilibrium states are identified in the improved viral model: the virus-clear steady state $\mathcal{G}^{\circ }$, the immunity-free steady state $\mathcal{G}_{1}^{\star}$ and the infection steady state with humoral immunity $\mathcal{G}_{2}^{\star }$. The local stability of the equilibria is investigated using the Routh-Hurwitz criteria and the Matignon condition, while the global stability is shown through the Lyapunov approach and the fractional LaSalle invariance principle. Finally, the theoretical conclusions are validated by numerous numerical simulations.

Published: January 2025

In this work, the bifurcation and hysteresis phenomena of the Euler beam problem are focused on from the singularity theory viewpoint. Confirming the continuity of the problem is a necessary condition for performing a bifurcation and hysteresis analysis. A bifurcation problem is transformed from an infinite dimension to a finite dimension by applying the Lyapunov equations. A suitable central force minimizes our considered model and makes the problem stable. Moreover, we perform numerical investigations and interpret the results obtained from the bifurcation and hysteresis analysis geometrically with suitable values of the new unfolding parameters and with different lengths.

Published: January 2025

The integration of technology into teaching and learning processes is highly relevant in today’s educational landscape, as technology has become essential for facilitating student learning. However, in practice, technology has not been fully optimized to develop students' critical thinking skills. The TPACK framework, which guides teachers in integrating technology into the learning process, must be continuously refined through relevant strategies. This study aims to describe how elementary school teachers' TPACK can be improved through collaborative, practical, and reflective approaches. A mixed methods design with an embedded experimental approach was employed. The study involved 84 teacher participants, randomly assigned to experimental and control groups. Data were collected using a 21st-century TPACK questionnaire and interviews. The findings indicate that collaborative, practical, and reflective approaches significantly enhanced elementary school teachers' TPACK. Statistical tests revealed a significant difference between the experimental and control groups, with the experimental group achieving higher average TPACK scores. Training that incorporates teacher collaboration, real-world classroom practices, and self-reflection effectively enhanced Technological Pedagogical Knowledge (TPK), contributing to the overall improvement of TPACK.

Authors: Rokayah Rokayah , Rahayu Ai Hayati
Published: January 2025

Teachers' reflective ability is a critical factor in improving the quality of learning in elementary schools. Reflection enables teachers to critically evaluate their teaching practices, identify strengths and weaknesses, and develop more effective strategies to address students' needs. This study aims to assess the level of self-reflective ability among elementary school teachers using a survey method and to explore how reflection contributes to enhancing teaching quality. The survey included 316 elementary school teachers from various regions in Indonesia and was conducted online using a teacher self-reflection questionnaire. The results revealed that teachers' reflective abilities were generally categorized as good. While most teachers acknowledge the importance of reflection, challenges remain in implementing deep and structured reflective practices. Key barriers include high workloads, limited time, and insufficient professional support. Furthermore, a lack of understanding of the reflective process and the absence of supportive tools to guide teachers through this process hinder the effective application of reflection.

Published: January 2025

Critical literacy has become an essential approach in education, yet research on its perception and implementation at the primary school level, particularly in EFL contexts, still needs to be completed. This study examines primary school teachers' perceptions of critical literacy in English as a Foreign Language (EFL) classroom in West Java. Using a mixed-methods approach, data were collected from 50 primary school teachers through structured surveys and open-ended questionnaires. Quantitative data were analyzed using descriptive statistics, while qualitative responses were analyzed thematically. Findings indicate a limited understanding of critical literacy, although teachers are strongly willing to incorporate it into their teaching. Key challenges include inadequate professional development, insufficient resources, and rigid curriculum constraints, emphasizing the need for targeted training to enhance students' learning experiences. Limitations include the small sample size and focus on one region. Future research should explore broader contexts and the longitudinal impacts of critical literacy practices. However, it is still expected that the study could give primary school teachers insight into critical literacy as one of the approaches in education.

Published: January 2025

Over the years, teaching has changed dramatically as both an art and a science, responding to the demands of students as well as advances in knowledge and technology. "Innovative and Traditional Types of Teaching: Bridging the Gap," an article, examines the dynamic interaction between contemporary educational innovations and conventional teaching techniques. Disciplined learning and knowledge preservation have been made possible by traditional teaching methods, which are based on teacher-centered techniques, rote memorization, and direct instruction. But as technology has advanced and learner expectations have changed, cutting-edge approaches like flipped classrooms, immersive learning, and individualized instruction have become powerful forces in education.
The article explores the advantages and disadvantages of both strategies. While contemporary approaches improve engagement, critical thinking, and flexibility to meet a range of learning requirements, traditional approaches are excellent at promoting fundamental skills and cultural continuity. The discussion highlights the possibility of combining both paradigms to produce a hybrid strategy that blends the flexibility of innovation with the rigor of tradition through a comparative study.
Case studies and real-world examples show how teachers can successfully combine these approaches to maximize learning results while tackling the particular difficulties presented by today's diverse classrooms. The article ends by promoting a balanced approach to teaching methods that embraces the potential of contemporary innovations to enhance the educational process while still honoring the timeless significance of conventional methods. In order to prepare students to succeed in a complicated, interconnected world, this synthesis is crucial.

Authors:   Department of Zoology, University of Science and Technology, Meghalaya, Basumatary Raj Kusum
Published: January 2025

Tea (Camellia sinensis) is the world's most popular non-alcoholic beverage, with India being one of the largest producers. In Northeast India, tea cultivation is highly susceptible to damage from insect pests and mites, leading to significant economic losses. Two of the most problematic pests for tea are the Tea Mosquito Bug (Helopeltis theivora) and the Red Spider Mite (Oligonychus coffeae). These pests feed on the tender parts of the tea plant, such as leaves, buds, and young shoots, resulting in decreased yield and quality. This review discusses the biology, damage, and management strategies for both pests, focusing on cultural, mechanical, and biological control methods. Integrated Pest Management (IPM) strategies including the use of natural predators, entomopathogens, and botanical treatments are highlighted as effective and sustainable approaches to mitigate pest-related losses.

Objective: To evaluate the association between dynapenic abdominal obesity (DAO) and the following negative outcomes in older patients with type 2 diabetes (T2D): prolonged length of stay (LOS), readmission within 30 days, in-hospital mortality, and mortality within 1 year after hospital discharge. Methods: This prospective cohort study included hospitalized older patients with T2D. DAO was defined as a combination of abdominal obesity (high waist circumference [WC]: ≥ 102 cm for men and ≥ 88 cm for women]) and dynapenia (reduced hand grip strength [HGS]: < ≤27 kg for men and < 16 kg for women]). The association between clinical outcomes and DAO was evaluated using multivariate analyses adjusted for confounders. The Kaplan-Meier curve was used to compare 1-year survival in the presence of DAO. Results: We included 309 patients with T2D (mean age 73.3 ± 6.4 years; 50.5% female; 32.4% with DAO). In multivariate analyses, patients with DAO had a 5.29- and 4.71-fold increase in LOS (≥ 14 days) and 1-year mortality than those without DAO, respectively. Moreover, patients with DAO had a higher risk of 1-year mortality (log-rank test, p < 0.05). Conclusions: Older patients with T2D and DAO are more likely to have prolonged hospitalization and 1-year mortality compared to those without DAO.

In order to encourage rural development and sustainable management of shrimp ponds in the Mahakam Delta area, the government and other organizations have initiated a mangrove planting program in green belts, inside ponds, and abandoned ponds as barren and inactive ponds that are degraded by pond extension through a mangrove planting program since 1999. It is indicated that the program's impact on the community in the Mahakam Delta could be realized when those local people participate more. The research involved 272 pond farmers and 33 stakeholders as the respondents. Analytical techniques for this study were descriptive statistics by applying the scoring on the Likert scale, and employing the chi-square test. The objectives of the study were (1) to measure pond farmers’ and stakeholders’ satisfaction with the mangrove planting program, (2) to analyze variables that correlate with pond farmers’ satisfaction with the mangrove planting program. The results showed that most pond farmers and stakeholders were well satisfied with the mangrove planting program in the Mahakam Delta. Pond farmers’ satisfaction was 7.7% in the highest score, 53.8% in the high score, and only 38.5% were at a low score. Also, 7.7%, 38.5%, and 38.5%, 15.4% of stakeholders’ satisfaction fell into highest, high, moderate, and low scores, respectively. In the analysis, three variables, which were the farming system adoption (Z1), education (Z2), and length of stay in the Mahakam Delta area (Z3) were associated with pond farmers’ satisfaction with the mangrove planting program. Therefore, the local people's satisfaction and characteristics can be considered in developing a strategy for the sustainability-enhancing of mangrove-shrimp farming management. Where, the government needs to realize the policies to mangrove trees planting within ponds, distance setting of green belt area, and improvement of skill and knowledge of local people.

This study aimed to evaluate the effect of the natural exploration method  on senior high school students' interest and learning motivation on biodiversity concepts. This method is thought to provide a more interactive and enjoyable learning experience through student involvement with the surrounding environment. The study was conducted on grade X students at one of the senior high schools in Tangerang Regency, Indonesia with 145 grade X students as research subjects, using a qualitative descriptive approach in the form of Classroom Action Research (CAR). Data were collected through observation and Likert scale questionnaires. The results showed that the application of the natural exploration method increased students' interest and motivation. The highest percentage of interest in learning was found in the statement that the exploration method makes biodiversity learning more interesting (53.8%), while the highest learning motivation was seen in students who felt more enthusiastic about learning biodiversity after the exploration activity (53.8%). However, some students admitted that they had difficulty understanding the teacher's explanation (33.8%) and rarely looked for additional information (40.1%). In conclusion, the natural exploration method is effective in increasing students' interest and motivation in learning, although improvements are still needed in several aspects of learning.

This study examined the preparation and implementation of outdoor learning by integrating STEM concepts into Biology Education. It highlights the opportunity for further investigation into how the STEM approach can enrich students’ learning experiences in outdoor learning. The research uses a case study method with a qualitative approach, where data is collected through observations and interviews to understand the implementation of Outdoor STEM Learning in Biology Education at high schools. Data collection was conducted at two schools, with two Biology teachers as informants from one high school in Banten and Jakarta. The findings reveal that both schools have not yet implemented the Outdoor STEM Learning concept in Biology Education. However, both show a growing interest and curiosity to adopt it, especially with the implementation of the Merdeka Curriculum. Challenges such as limited resources, facilities, and teacher training pose obstacles, but it is hoped that this implementation could enhance learning experiences, strengthen the understanding of Biology, and develop students’ character.

This research aimed to develop a conservation e-book based on local potential to improve the eco-literacy of junior high school students. The development of the e-book is based on the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) which was conducted on 27 seventh-grade students using a one-group pretest-posttest design. The development instruments were in the form of validation forms, eco-literacy questions, and questionnaires as well as student response surveys to conservation e-books. Analysis was conducted on the results of validation of e-book feasibility, increase in gain value, and hypothesis testing. The results of data analysis showed that the developed conservation e-book was declared valid with a percentage of 93.20% from material experts and 93.39% from media experts. In addition, after using local potential-based conservation e-books, there is an increase in eco-literacy with an average N-Gain value of 0.65 (knowledge competency) and 0.46 (attitude competency, skills, and human relations with nature) respectively, including in the moderate category. The test of the effectiveness of eco-literacy knowledge competence using the Paired-T Test shows a sig. value of 0.000, as well as the competence of attitudes, skills, and human relations with a nature of 0.000. Students' response to the e-book was very good as indicated by a percentage value of 94%. Thus, conservation e-books based on local potential can improve students' eco-literacy and are effectively used in the science learning process.
