Abstract

Obesity and headache are conditions associated with a substantial personal and societal impact. This study aims to evaluate the association between body mass index (BMI) and Headache among adults in Gharyan City, Libya. This was a descriptive cross-sectional study, conducted at Gharyan city, Libya, during the period from December 2024 to March 2025. Two hundred (200) participants, including 94 males (47%) and 106 females (53%), were enrolled in this study. Data were collected by using a structured questionnaire. The participants were divided into four categories, based on BMI: underweight (<18.5), normal weight (18.5 to 24.9), overweight (25 to 29.9), and obese (>30). A total of 200 participants, both gender males and females, were enrolled in this study during the study period. The study indicates that high percentage of headache in age was 43 -56 years, and severe obesity BMI > 30 kg/m2 were observed of high percentage in females n=27 (25.47%) compared to males n=17 (18.08%), although the severe obesity and headache found in females n=37 (34.90%), rather than males n=30 (31.91%) Obesity and headache are both, slightly more common in females than males, we recommend that more studies among obesity and headache in large patients should be done, although small sample size and lack of long-term flow-up of patients, were the main limitations of our study and results suggested a need for monitoring by X-ray and MRI diagnosis of patients have obesity

Abstract Classroom presentations represent an important aspect of activities that help English as a Second Language learners showcase their language skills, particularly speaking in front of others, and reveal the educational and psychological obstacles and challenges they face in performing these presentations at the best possible level. The study aims to identify the impact of language anxiety on classroom presentations by applying it to English as Foreign Language learners at Gharian University, which helps to investigate the level and type of anxiety that English as a Foreign Language students at the university suffer from during presentations. The study was conducted on various students of different semesters at University. The sample consisted of 100 students of both genders, divided into two groups (45 males and 45 females), during the academic year 2025-2026. The study relied on a questionnaire as the data collection tool, and the collected data was statistically analyzed using SPSS software. The results showed a high level of anxiety about learning English among the participating students for various reasons. A statistically significant inverse relationship was found between the level of English language anxiety among University students and the quality of their classroom presentations. Statistically significant differences were also found in language anxiety levels among students during classroom presentations, while no statistically significant differences were found between gender and anxiety levels in terms of their impact on the quality of classroom presentations. The stuconcluded with recommendations and suggestions to enhance the

Abstract

Natural dentin repair is a biologically mediated process that preserves tooth vitality through odontoblast activity and intracellular signaling pathways. This study employed a mixed methods design, combining laboratory experiments with descriptive analytical surveys of dentists in Egypt, to investigate the mechanisms of odontoblast differentiation and assess clinical knowledge and practices related to regenerative dentistry. Laboratory analyses included microscopic and molecular techniques to evaluate cellular signaling during dentin repair, while questionnaires were distributed to 100 dentists across public and private sectors. Data were analyzed using quantitative statistics, qualitative assessments, and integrative interpretation of laboratory and clinical findings. Results revealed significant positive correlations between dentists’ knowledge of intracellular signaling and their clinical practices, with Spearman correlation coefficients ranging from 0.52 to 0.65 (p = 0.01). A majority of respondents (80%) reported experience with mesenchymal stem cell therapy for craniofacial bone remodeling or dental tissue regeneration, and 70% observed improvements in bone density, while 65% reported enhanced dental tissue regeneration. Imaging studies were widely used, with 85% of participants undergoing radiographic or CT evaluations to monitor progress. Despite these encouraging outcomes, only 35% of dentists were familiar with molecular techniques targeting signaling pathways, and just 40% reported applying clinical strategies to enhance odontoblast differentiation. Notably, 75% expressed interest in specialized training to improve their knowledge and practices in regenerative dentistry. The study concludes that while theoretical awareness of dentin repair mechanisms is relatively strong, clinical application remains limited. Bridging this gap through structured training and evidence-based protocols will be essential for integrating molecular insights into routine dental practice, thereby improving dentin repair outcomes and long-term tooth vitality.

Abstract

The proper management of biological waste in laboratory settings is a critical aspect of biosafety in microbiological and biomedical laboratories. Beyond protecting lab workers, biological waste management safeguards public health, protects the environment, and ensures compliance with legal and regulatory frameworks. Segregation, decontamination of liquid waste, decontamination of solid waste, and techniques for inactivating toxins are all main aspects of biological waste management that will be outlined, aligned, and summarized with the main institutional biosafety protocols for biological waste management, published by major authorities, including CDC and WHO. This research found that the information from the two institutions complements each other. Therefore, this brief review aimed to compile and unify information from both institutions to construct a single, coherent text that provides a practical summary for medical laboratory professionals seeking to enhance the implementation of international, harmonized protocols that strengthen biosafety, environmental stewardship, and regulatory compliance

Antimicrobial Susceptibility Testing (AST) is essential for guiding appropriate antibiotic therapy. The disk diffusion method is widely used in Libya due to its low cost, yet deviations from standardized protocols can compromise result accuracy, affecting clinical decisions and patient outcomes. This study evaluated the performance of the disk diffusion AST method in medical laboratories in Gharyan, Libya, using EUCAST guidelines (version 12.0) as a benchmark. Seventy-five AST plates representing 122 clinical specimens were randomly collected from three pathology centers between September and November 2025. Plates were analyzed for the type of culture media, number of specimens per plate, number of antibiotic disks, and readability of results. All plates were 90 mm in diameter. Nutrient agar was used for 118 specimens, and blood agar for two; none used Mueller-Hinton agar as recommended. Only 17% of plates tested a single specimen per plate; the majority tested one specimen on half or a quarter of a plate. The number of antibiotic disks per specimen often exceeded EUCAST limits (up to 20 disks per plate), and only 8% of plates yielded readable results. Widespread deviations from EUCAST protocols—including inappropriate media, specimen overloading, and excessive disks—compromise AST reliability. These errors may lead to incorrect antibiotic prescriptions, delayed recovery, and increased antimicrobial resistance. Strict adherence to standardized guidelines is urgently required to ensure accurate, clinically meaningful AST results. Moreover, raising awareness of the importance of following standard guidelines is crucial for correcting the course

Despite the critical demand for advanced English proficiency in Libyan 

higher education, primary public schools, particularly in rural areas, have 

been neglected. This qualitative study investigates the imperative for 

implementing improved methodologies in Teaching English as a Foreign 

Language (EFL) in Libyan primary public schools, using the post-conflict 

rural municipality of Al Gwaleesh as a case study. Data were collected by 

questionnaires and classroom observations from ten teachers and ten third

year pupils. The findings reveal a systemic reliance on traditional Grammar

Translation Methods, a stark deficiency of resources (including basic 

teaching aids and ICT), and minimal student engagement. Teachers 

demonstrated limited application of Communicative Language Teaching 

(CLT) principles, focusing predominantly on rote memorization and written 

exercises. Consequently, pupils reported low motivation and a failure to 

grasp the language's practical utility. The study concludes that a 

fundamental overhaul of EFL pedagogy in Libya is urgently required, 

recommending the integration of audio-visual aids, activity-based learning, 

and 

strategic 

incorporation 

of 

Information and Communication 

Technologies (ICTs) to foster intrinsic motivation and build a sustainable 

foundation for English proficiency.
