Comparative Structural Behavior of Sustainable Fibrous Voided Ferrocement Slabs Incorporating Waste Glass Powder and Different Void Formers

Ferrocement slabs, being lightweight and sustainable, can help in achieving resource-efficient construction by reducing material consumption while maintaining satisfactory structural performance. The flexural behavior of environmentally friendly ferrocement slabs with recycled ma...

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...

Holistically benchmarked optimization-assisted green spectrophotometric–chemometric approach for simultaneous determination of piroxicam and venlafaxine in pharmaceutical formulations and spiked human plasma

The recent clinical introduction of the piroxicam (PIR) and venlafaxine hydrochloride (VEN) combination has highlighted the need for analytical methodologies capable of simultaneously quantifying both drugs while minimizing the environmental burden of routine pharmaceutical analy...

Natural Biodegradable Polymer-Based Microneedles for Controlled Drug Delivery: A Rational Design Framework and Translational Perspectives

Microneedle (MN) technology has emerged as a promising minimally invasive platform for transdermal drug delivery, enabling efficient transport of therapeutic agents across the stratum corneum while improving patient compliance. In recent years, natural biodegradable polymers have...

Does patient death and suffering deplete or energize ICU healthcare professionals? Daily interaction of harmonious and obsessive passion

This study examined the moderating role of daily harmonious passion (HP) and obsessive passion (OP) in the association between daily contact with patient death and suffering, and daily burnout and vitality. Grounded in job demands-resources theory, HP was expected to serve as a p...

Molecular modeling characterization of cellulose and chitosan metal oxide hybrid interfaces

Abstract The interfacial electronic structure of biopolymer–metal oxide hybrids determine their stability, yet this structure is still not well understood. Here, we report a density functional theory study of 10 model systems consisting of cellulose and chitosan functionalized wi...

Clinical consequences, treatment status, and parental awareness of traumatic dental injuries among high school students: a cross-sectional study in Cairo

Abstract Background This study assessed the current clinical consequences and treatment status of previous traumatic dental injuries (TDIs) affecting permanent anterior teeth among adolescents aged 15–17 years in Cairo, Egypt, and evaluated parental awareness and knowledge regard...

Bioactive goldenseal (Hydrastis canadensis) fraction suppresses multidrug-resistant Pseudomonas aeruginosa in a rat burn wound model: oral and topical administration

Abstract Multidrug-resistant (MDR) Pseudomonas aeruginosa is a prominent pathogen implicated in burn wound infections, creating substantial therapeutic obstacles due to its antibiotic resistance and enhanced virulence mediated by quorum sensing (QS). This study explored the anti-...

Safety and efficacy of ertugliflozin on heart failure outcomes across cardiovascular diseases: a systematic review and meta-analysis

Sodium-glucose cotransporter-2 inhibitors (SGLT2is) improve cardiovascular outcomes in patients with heart failure (HF) and type 2 diabetes (T2D). However, the efficacy of individual SGLT2is, particularly ertugliflozin, remains less defined. This systematic review and meta-analys...

Reducing Peak Load Underprediction Through Risk-Aware Upper Quantile Forecasting: A University Laboratory Case Study

Underprediction of high electrical demand can be more operationally consequential than an equally sized overprediction, yet standard point forecasting models are optimized primarily for average error. This case study evaluates a multivariate quantile Transformer as a safety-orien...

Improvement of Rock Grouts Using Eco-Friendly Lightweight Geopolymer Mortar Modified with Castor Oil-Based Rigid Polyurethane Foam

Conventional cement-based grouts used to stabilize fractured rock slopes and fill large cavities are heavy, carbon-intensive, and can impose excessive dead load on weakened rock masses. This study addresses these limitations by integrating bio-based rigid polyurethane—particularl...

Passive surveillance of infectious bursal disease virus circulating in Egyptian chicken flocks in 2025

Abstract Infectious bursal disease virus (IBDV) causes severe immunosuppression diseases in poultry, resulting in substantial economic losses for the global poultry industry. This study aimed to characterize circulating IBDV strains in Egyptian chicken flocks and assess their pot...
