Work Perception and Perceived Stress Among Nurses and Interns Working in the Critical Care Units in Jeddah, Kingdom of Saudi Arabia

Objectives Work perception is a very important component that has both positive and negative influences on the stress perceived by the employees of any organisation. This study was carried out to examine the correlation and association between work perception and stress levels am...

Application of in vitro digestion and dialysability procedure for bioavailability evaluation of toxic elements in green leafy vegetables: a realistic health risk assessment by Monte Carlo simulation

Green leafy vegetables (GLVs), which are vital and widely consumed worldwide, require monitoring for contaminants, including toxic elements (TEs). This study measured total concentrations (TC) and bioavailable concentrations (BC) of arsenic (As), cadmium (Cd), lead (Pb), chromium...

Theoretical Investigation of Linear Polarization Effects on Electron—Positron Pair Production in the Electromagnetic Field of Be49 Nucleus

Electron–positron pair production is one of the fundamental quantum electrodynamical (QED) processes and provides an important framework for investigating photon–matter interactions. In this work, the influence of linear photon polarization on electron–positron pair production in...

Sustainable Leadership, Workplace Integration, and Resilience Among Staff Nurses: A Cross-Sectional Correlational Study

Background: Sustainable leadership has emerged as a critical approach for promoting long-term organizational effectiveness and workforce well-being in healthcare settings. However, empirical evidence linking sustainable leadership to workplace integration and resilience among nur...

Tailored novel nanocomposites for advanced elimination of methylene blue dye from water

Novel SrCO 3 /CuO/MgO/C (Abbreviated as CSM600) and SrCO 3 /CuO/MgO/Sr 2 CuO 2 CO 3 /Cu 2 SrO 3 /SrCuO 2 /C (Abbreviated as CSM800) multiphase nanocomposites were successfully synthesized through a Pechini sol–gel route followed by calcination at 600 and 800 °C. Structural analys...

Predicting the Unwelcome Return: Insights From a Cohort of Postoperative Haemorrhoid Patients

AIM: Recurrence after haemorrhoid surgery is a clinical concern, but the factors associated with recurrence have not yet been fully elucidated. In particular, the effects of external haemorrhoids and postoperative complications on long-term outcomes have not been clearly defined....

Phytochemical profile and in vitro antimicrobial, antiviral, and anticancer activities of Echium angustifolium ethanolic extract

Echium angustifolium is traditionally valued for its therapeutic properties; yet comprehensive studies on its biological activities are limited. Aerial flowering parts were sequentially extracted with solvents of varying polarity. Extracts were analyzed for yield, phytochemical c...

Effect of Different Metal Doping of ZnO Nanoparticles on Photocatalytic Degradation of Dye Wastewater

Undoped ZnO and metal-doped ZnO (ZnO:M) nanoparticles (NPs), with M [Formula: see text] Ca, V and Al, have been synthesized, with the same metal content ([Formula: see text]%), by the sol–gel method. The M-doping effects on the ZnO NPs properties are studied by a variety of techn...

A numerical study of non-Newtonian blood-based hybrid nanofluid flow over a stretching cylinder with Cattaneo–Christov heat flux and homogeneous heterogeneous reactions

Non-Newtonian hybrid nanofluids have attracted considerable attention in biomedical and industrial thermal systems because of their superior heat transfer performance and complex transport characteristics. In particular, blood-based hybrid nanofluids containing copper (Cu) and al...

Combined Omeprazole and Glycyrrhiza glabra L. Extract Attenuate Ethanol-Induced Gastric Ulceration Through Modulation of TLR4/NF-κB/NLRP3 Signaling and Upregulation of PI3K/AKT/mTOR Gene Expression

Ethanol (EtOH)-induced gastric ulcer (GU) is a common model used to investigate mechanisms of mucosal injury and repair. Omeprazole (OMP) is a conventional anti-ulcer drug that effectively suppresses gastric acid secretion, but its efficacy may be enhanced by combining it with bi...

Machine learning and deep learning techniques for effective supply chain management

The growth in data volume and complexity of decision-making create the need for new data analytics methods, such as machine learning (ML) and deep learning (DL), which are critical for improving various tasks in supply chain management (SCM). Recent studies have highlighted the b...

A multiplicative additive bias variational framework for accurate and interpretable brain MRI segmentation in cloud-based medical imaging systems

Abstract Accurate brain magnetic resonance imaging (MRI) segmentation remains challenging due to intensity inhomogeneity, acquisition-related bias fields, and ambiguous tissue boundaries. To address these challenges, a Multiplicative–Additive Bias Single-Function Dual-Level-Set (...

Can Carica papaya Serve as an Adjunct to Semaglutide in Mitigating Diabetes-Induced Testicular Injury Through Modulation of Oxidative Stress, Inflammation, Apoptosis, and the miR-34c/miR-155–SIRT1/FOXO1 Axis? An Experimental and Chem-Bio-Informatics Study

Diabetes mellitus (DM) induces significant endocrine disruption and oxidative stress (OS) within the testes, resulting in impaired spermatogenesis, increased sperm abnormalities, and compromised reproductive function. This study aimed to evaluate the combined protective effects o...

Digital epidemiology investments, Saudi Arabia.

Problem: Traditional epidemiological surveillance methods are often limited by delays in reporting and fragmented data systems. Saudi Arabia faces additional public health challenges from mass gatherings during Hajj and Umrah, an increasing burden of noncommunicable diseases and...
