Breastfeeding Attitudes and Early Postpartum Breastfeeding Practices Among Turkish and Syrian Immigrant Mothers: A Comparative Study

Breastfeeding is a key public health practice that promotes the health and well-being of both mothers and infants. However, migration-related experiences, socioeconomic conditions, and access to breastfeeding support may influence breastfeeding attitudes and practices among immig...

Gendered career motivations of female preservice mathematics and science teachers: a qualitative study

Although extensive research has examined women’s participation in mathematics- and science-related fields and motivations for entering the teaching profession, considerably less is known about how women choose mathematics and science teaching, which lies at the intersection of th...

Protocol for genome-wide differential methylation using long-read DNA sequencing in the cortex of a mouse model of Alzheimer’s disease

Third-generation sequencing enables direct detection of genome-wide 5-methylcytosine without bisulfite conversion. Here, we present a protocol for generating long-read DNA sequencing from mouse cortex and performing genome-wide differential methylation analysis. We describe steps...

Examining Peer Bullying, Empathy, and Social Anxiety in Gifted and Typically Developing Students

This present study aims to examined differences in peer bullying, empathy, and social anxiety between gifted and typically developing students. A correlational survey design was employed within a quantitative research framework. The sample consisted of 161 children and 406 adoles...

Vitamin A and D Status, Selected Genetic Variants, and Allergy-Related Phenotypes: An Exploratory Retrospective Study

Background/Objectives: Vitamins A and D are critical regulators of immune function, and genetic variation in their metabolic pathways may influence vitamin status and immune responses. This study investigated the combined nutrigenetic roles of vitamins A and D and their associati...

Investigation of arterial blood flow changes according to compression level in a practical blood flow restriction training method: A cross-sectional experimental study

Background Blood flow restriction (BFR) training is used to partially restrict limb blood flow during exercise. Practical blood flow restriction (pBFR) applications often rely on subjective pressure scales; however, the extent to which perceived compression levels influence arter...

Performance of Large Language Models in Answering Juvenile Systemic Lupus Erythematosus Questions: A Blinded Expert-based Comparative Study

Background: Large language models are increasingly used to obtain medical information, but their performance in juvenile systemic lupus erythematosus remains insufficiently characterized. Objective: To compare expert-rated response quality and clinical relevance across 4 artifici...

Perceived criminal behavior in frontotemporal dementia: A 10‐year retrospective analysis of forensic cases in Türkiye

Abstract Frontotemporal dementia (FTD) is associated with a disproportionately high risk of behavior perceived as criminal, yet systematic forensic data from non‐Western settings remain scarce. This retrospective descriptive study characterized the sociodemographic, clinical, and...

Beyond permission: Reconsidering anatomy education through a contemporary Islamic fatwa in Türkiye

Abstract The ethical use of human body donors in anatomy education is shaped by scientific and professional standards as well as cultural, societal, and religious contexts. In Türkiye, body donation remains limited, and anatomical institutions continue to rely partly on unclaimed...

Heart sound classification using machine learning approaches based on mel-frequency cepstrum coefficients (MFCCs) and statistical features

Heart sounds provide a valuable non-invasive source of information for the early detection of cardiac abnormalities. However, reliably distinguishing normal from abnormal heart sounds remains challenging in routine clinical practice because interpretation depends strongly on expe...

Investigation of polyetheretherketone as secondary crown material with an occlusal gap in double crowns

The use of polyetheretherketone (PEEK) in double crowns has gained increasing attention but the effect of an occlusal gap on various double crown assemblies involving PEEK material has not been thoroughly investigated although it has a critical influence on the retention mechanis...

Association of Gastric Microbiota with Gastric Cancer in Patients Infected with Helicobacter pylori

Background: The association between Helicobacter pylori and the resident gastric microbiota plays a critical role in gastric carcinogenesis; however, the specific microbial alterations accompanying the transition from chronic inflammation to malignancy remain to be fully elucidat...

Prediction of Ultra-High-Performance Concrete (UHPC) Compressive Strength in Structural Applications Using Machine Learning: A Comprehensive Evaluation via Multiple Random Seeds and Hyperparameter Optimization

Ultra-high-performance concrete (UHPC) is increasingly being used in academic and commercial applications due to its superior mechanical properties, high durability, and long service life. To ensure that UHPC can be reliably used in structural applications, it is important to pre...

“It’s not just the pain” understanding fear of childbirth through the lens of body and mind

This study investigated the relationship between haptotherapeutic well-being and fear of childbirth and examined the influence of sociodemographic factors on these variables. A cross-sectional analytical study was conducted with 567 pregnant women receiving antenatal care in east...

Artificial Intelligence for Distinguishing Glaucoma From Its Mimickers: A Narrative Review of Diagnostic Pitfalls, Validation Gaps, and Clinical Translation

ABSTRACT Artificial intelligence (AI) has advanced rapidly in glaucoma, but many models remain optimized for case‐control detection rather than the clinically harder task of distinguishing glaucoma from its mimickers. This narrative review primarily examined literature published...

Fresh-semen proAKAP4 concentration predicts sperm cryotolerance independently of conventional semen quality across three goat breeds

Abstract Cryopreservation compromises sperm quality, yet conventional semen analysis poorly predicts which ejaculates will withstand freezing. proAKAP4, a sperm-specific structural protein, is a candidate freezability biomarker, but is usually measured after thawing. We tested wh...
