Disability, Fatigue and Mental Health in Acute Versus Chronic Spinal Pain in the Gaza Strip: A Comparative Cross‐Sectional Study

ABSTRACT Background Spinal pain is a major contributor to disability, but evidence comparing multidomain outcomes across acute and chronic stages remains limited in conflict‐affected settings. This study aimed to compare disability, fatigue, psychological distress and sleep distu...

Biopolymer Silica Hybrids as Superior Nanocarriers for Anticancer Drug Delivery

Abstract Liposomal carriers are widely used for anticancer drug delivery due to their biocompatible nature in the biological milieu. Liposome-based drugs often face premature leakage, uncontrolled release, and insufficient control over long-term drug availability. Here, we presen...

Ethnopharmacological insights into type 2 diabetes management by traditional Moroccan herbal teas: HPLC-MS characterization of phenolic compounds and their related antioxidant and enzyme inhibitory activities

Abstract Background Traditional Moroccan herbal teas are widely consumed and have been traditionally used for managing chronic metabolic disorders, particularly type 2 diabetes mellitus (T2DM). Although these preparations have a long history of ethnomedicinal use, their phenolic...

Beyond symbolic: can SDGs disclosure mitigate the negative impact of ESG reputational risks on firm value? A firm-level analysis

Purpose Drawing on the substantive role of SDGs disclosure, this paper aims to examine the nexus between firm value, Environmental, Social and Governance (ESG) reputational risks and SDGs by investigating whether these SDGs disclosure practices can mitigate the negative impact of...

Limiting dengue transmission using a differential game approach

In this paper, a fundamental structural asymmetry in dengue fever epidemic control approaches is identified and formalized. We show that treatment and quarantine interventions must influence the sick compartment, whereas the majority of epidemic game models treat interventions as...

Influence of fin geometry on heat transfer and friction in plate fin heat exchangers: a CFD approach

Abstract Plate fin heat exchangers (PFHEs) are widely recognized for their compact design and high thermal efficiency, making them a popular choice in various heat transfer applications. Some common types of geometries which are used in the case of PFHEs are rectangular fins, tri...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

ABSTRACT The navigation and control of untethered magnetic robots (UMRs) within soft brain tissue critically depend on their ability to maintain synchronized rotation under applied rotational magnetic fields. The fundamental upper limit of this magnetic synchronization, known as...
