Mesenchymal stem cells modulate pancreatic and splenic inflammation through PI3K/AKT/mTOR and TGF-β signalling in diabetic rats

Bone marrow-derived mesenchymal stem cells (MSC) can attenuate diabetic organ damage through immunomodulatory and paracrine mechanisms, yet the specific signalling pathways engaged in the pancreas and spleen remain poorly characterized. This study investigated the effects of a si...

Deciphering Precambrian Litho-structural settings and barite-associated mineralization through integrated hyperspectral and geophysical datasets

Effective lithological mapping and mineral exploration remain challenging in geologically complex and underexplored Precambrian terrains. This is particularly relevant to the Arabian–Nubian Shield (ANS), a Neoproterozoic orogenic belt extending across northeastern Africa and Arab...

Experimental Investigation on a Tubular Solar Still Using Custard Apple Seeds: A Sustainability Study

ABSTRACT This study investigates the thermodynamic and water‐production performance of a conventional tubular solar still (CTSS) compared with a tubular solar still (TSS) utilizing custard apple seeds (TSS–CAS). The cumulative distillate yield of the TSS–CAS reached 3.60 kg/day,...

Socioeconomic determinants of maternal and neonatal healthcare utilization among recently delivered women in Sudan

Armed conflict and economic instability can exacerbate socioeconomic inequalities in maternal and neonatal healthcare access and utilization. This study assessed the association between household income, healthcare costs, and maternal and neonatal healthcare utilization among wom...

Beyond Tokenism: The Role of Critical Mass of Female Directors, Female Chair Leadership, and Stakeholder Orientation on CSR Reporting Tone

ABSTRACT In this paper, we examine the association between the critical mass of female directors, female chair leadership, and the linguistic tone of CSR narratives, and whether country‐level stakeholder orientation moderates these relationships. Using a dictionary‐based textual...

ON PAIRWISE ALMOST QUASI-CONTINUOUS MAPPINGS IN BITOPOLOGICAL SPACES

Almost quasi-continuity, introduced by Popa (1978) in the setting of classical topological spaces, has played an important role in the development of generalized continuity concepts. Motivated by the increasing interest in continuity notions within bitopological frameworks, this...

Reinforcement learning for sustainable construction scheduling: a many-objective framework with adaptive search and multi-criteria decision support

Purpose Delivering construction projects sustainably requires reconciling duration, cost, carbon emissions and the stability and utilization of site resources, yet these objectives conflict and the choice among candidate schedules is seldom made on an explicit, data-driven basis....

Intracanal cryotherapy and postoperative pain relief in symptomatic apical periodontitis: a systematic review and meta-analysis

Postoperative pain remains a frequent complication following nonsurgical root canal treatment and is particularly associated with inflammatory pulpal and periapical conditions. Intracanal cryotherapy has been proposed as a simple and biologically plausible adjunctive strategy aim...

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...

A cell-free therapeutic strategy using MSC-derived exosomes and activated platelet lysate for acute kidney injury induced by rhabdomyolysis

Abstract Rhabdomyolysis-induced acute kidney injury (AKI) is primarily driven by myoglobin-mediated tubular toxicity, leading to pronounced oxidative stress, inflammation, and apoptosis. Given the limited availability of effective targeted therapies, this study aimed to evaluate...

Dietary dose-dependent effects of Ginkgo biloba leaf extract on growth, immunity, antioxidant status, and hepatic integrity in Nile tilapia

Abstract The increasing demand for sustainable alternatives to in-feed antibiotics has stimulated interest in phytogenic feed additives. This study investigated the dose-dependent effects of dietary Ginkgo biloba leaf extract (GBLE: 0, 6, 12, 18, and 24 g/kg diet) in Nile tilapia...

Cryoneurolysis as an effective spasticity treatment option : a case series

Abstract Background Achieving effective treatment for spasticity remains a clinical challenge. The commonly used available options are either physical therapy ( stretching, electric stimulation, local heat or cold therapy), medical treatment either oral or injectable therapy even...

Evaluating the Techno‐Economic Feasibility of Grid‐Connected Hybrid Renewable Energy and Storage System

ABSTRACT Focusing on the renewable energy potential of Hurghada, Egypt, this study analyzes a grid‐integrated system that utilizes DSSC technology, wind turbines, and battery storage. A multi‐dimensional assessment is conducted, encompassing techno‐economic modeling, environmenta...

Development and structural validation of the Artificial Intelligence Competency Scale for Nurse Educators (AI-CSNE): a three-domain measure of perceived AI competency

The rapid integration of artificial intelligence (AI) into healthcare and nursing education has created new competency requirements for nurse educators. Despite this growing demand, there is a notable lack of rigorously developed and psychometrically validated instruments specifi...

Effect of a structured nurse-led empowerment protocol on knowledge, practical skills, and self-care behaviours among patients with permanent pacemakers: a quasi-experimental study

Abstract Background Patients with permanent pacemakers frequently demonstrate insufficient knowledge and inadequate self-care behaviours, which increase the risk of avoidable post-implantation complications. Structured, theory-informed empowerment protocols may improve these outc...

Experimental and numerical investigations of UHPFRC-filled circular steel tubular columns under axial and lateral cyclic loads

Abstract This study investigates the seismic performance of ultra-high-performance fiber-reinforced concrete (UHPFRC)-filled circular steel tubular columns through experimental testing and numerical simulation. Eight specimens were tested under combined axial and lateral cyclic l...
