A multifunctional Tb3+–salicylic acid hydrazide phosphor for anti-counterfeiting, forensic fingerprint visualization, and biological applications

Abstract A novel terbium(III) complex, Tb(SAH) , derived from salicylic acid hydrazide ( SAH ), was successfully synthesized and fully characterized. Stoichiometric analysis confirmed a 1:2 metal-to-ligand ratio. X-ray diffraction and microscopic studies revealed a polycrystallin...

Briefing: From urban foresight to project bundles—the case of Huntsville, Alabama

Urban foresight and its project packages may follow linear temporality paths towards intended urban futures. Changes in conditions in one project package might affect the others. This briefing argues that project bundling can offer a more dynamic way to implement these visions. S...

Ebola Virus Persistence in Immune-Privileged Niches: Molecular Mechanisms, Host–Virus Interactions, and Therapeutic Opportunities

Ebola virus disease (EVD) has traditionally been conceptualized as an acute, fulminant illness culminating in either death or apparent systemic viral clearance. However, clinical, virological, and genomic evidence gathered since the 2013–2016 West African epidemic demonstrates th...

A biomimetic 3D printed gradient tri-layered scaffold stimulating osteochondral differentiation of mesenchymal stem cells for mandibular condyle regeneration

Abstract Objectives This study aimed to fabricate and assess the physical, mechanical, and in vitro biological properties of 3D printed single-layered scaffolds that simulate cartilage, calcified cartilage, and subchondral bone tissue. As well as a tri-layered osteochondral scaff...

Mapping the vulnerability of the Egyptian spiny-tailed lizard ( Uromastyx aegyptia ) in Egypt to climate change: Distributional shifts and conservation needs

Climate change has the potential to significantly impact species distributions and patterns of biodiversity, resulting in shifts, contractions in range and even extinction. The Egyptian spiny-tailed lizard (Uromastyx aegyptia), classified as a vulnerable species, faces threats pr...

Next-Generation Water Quality Monitoring via Artificial Intelligence-Coupled Nanozymes

Abstract Safe water management requires rapid and highly sensitive analytical platforms capable of detecting contaminants in complex environmental matrices. Nanozymes are nanomaterials with enzyme-mimicking catalytic activity that offer remarkable advantages for field-deployable...

Prophylactic administration of probiotic strains Weizmannia coagulans and Saccharomyces boulardii attenuates early dysplastic changes in an AOM/DSS-induced mouse model

Abstract Background Colorectal dysplasia represents an early stage of colorectal carcinogenesis and is closely associated with chronic inflammation and altered microRNA (miRNA) expression. Probiotic strains such as Weizmannia coagulans (formerly Bacillus coagulans) and Saccharomy...

Surgeons and Experts’ Perspectives in Concomitant Bariatric Surgery with Cholecystectomy: Bari-Chole Egypt Survey

INTRODUCTION: The management of gallbladder disease during metabolic and bariatric surgery (MBS) remains controversial. Cholelithiasis is common in patients with obesity, yet the approach to concomitant or prophylactic cholecystectomy varies, with limited data from Egypt. This st...

Celiac disease and gluten-free diet-related nutritional knowledge among medical students and internship doctors in Palestine: a cross-sectional training-needs assessment

Abstract Background Celiac disease management requires lifelong adherence to a gluten-free diet, alongside nutritional monitoring, diet-quality assessment, and dietitian support. Data on Palestinian medical trainees’ preparedness for these tasks are limited. This study assessed c...

An Interpretable XGBoost-SHAP framework for rapid regional assessment of liquefaction-induced lateral spreading in mildly sloping ground

Liquefaction-induced lateral spreading poses significant risks to infrastructure on mildly sloping ground during earthquakes. This study develops an interpretable machine learning (ML) framework for rapid regional-scale prediction of liquefaction-induced displacement using an Ext...

CrossCD-Eval: a unified framework with domain-aware feature normalization for cross-domain remote sensing change detection

Abstract Change detection (CD) in remote sensing imagery is essential for monitoring urban growth, land-use transformation, and environmental dynamics. However, cross-domain change detection remains challenging due to distribution shifts caused by differences in geographic region...

Omega-3 pretreatment modulates postmortem biochemical and histopathological changes following heat stroke: an experimental study on adult male albino rats

Abstract Background Accurate estimation of the postmortem interval (PMI) remains a major challenge in forensic science because postmortem changes are strongly influenced by environmental temperature. Increasing heat-wave frequency associated with global warming may alter these ch...

Cecal duplication cyst in an older child: a case report

Cecal duplication cysts are rare congenital gastrointestinal anomalies that are most commonly diagnosed in infancy. Presentation beyond early childhood is unusual and may lead to misdiagnosis because symptoms often mimic common pediatric gastrointestinal conditions. Reporting suc...

Prevalence of gastroesophageal reflux disease and associated risk factors among medical students in the MENA region: a multinational cross-sectional study

Abstract We aimed to assess the prevalence of gastroesophageal reflux disease (GERD) among medical students in Middle East countries and its associated risk factors. A multinational cross-sectional study was conducted among medical students in 8 Middle East countries. GERDQ and G...

Structure property and wear correlations in Al–Ni intermetallic coatings produced by atmospheric plasma spraying

Abstract Atmospheric plasma spraying (APS) is widely employed to fabricate protective coatings for engineering components requiring enhanced wear resistance and thermal stability. This study establishes structure property wear correlations in Al–Ni intermetallic coatings deposite...

Frequency of pathological gambling among Egyptian patients with substance use disorders: a cross-sectional study

Abstract Background Pathological gambling and substance use disorders (SUDs) share overlapping neurobiological pathways and clinical features. However, the prevalence of pathological gambling among Egyptian patients receiving treatment for SUDs remains insufficiently explored. Ob...

Microcomputed tomographic evaluation of root filling removal techniques in long oval mandibular premolar canals

Abstract This investigation evaluated the efficiency of various root canal filling removal techniques in removing gutta-percha (GP) and iRoot SP sealer in mandibular premolars with long-oval shaped canal using micro-computed tomography (micro-CT). Forty-eight mandibular premolars...

Carotid artery stenting utilizing self-expansion without post-stenting angioplasty in patients at high risk for reperfusion injury (a pilot study of a technical modification)

Carotid artery stenosis accounts for 15–20% of cerebrovascular ischemic strokes. Endovascular carotid artery stenting (CAS) has been recognized as an alternative treatment method for carotid artery stenosis with outcomes similar to carotid endarterectomy (CEA) [ 1 ]. One of the m...

BRCA1/2 variant profiling and HPV/HMTV DNA detection in a cohort of Egyptian women with breast cancer

Abstract Breast cancer (BC) is a multifactorial disease influenced by both genetic and environmental factors. Pathogenic variants in BRCA1 and BRCA2 significantly increase hereditary BC risk, while oncogenic viruses such as human Papillomavirus (HPV) and human mammary tumor virus...
