Activated carbon and their nanocomposites derived from vegetable and fruit residues for water treatment.

Water pollution remains a pressing environmental issue, with diverse pollutants such as heavy metals, pharmaceuticals, dyes, and aromatic hydrocarbon compounds posing a significant threat to clean water access. Historically, biomass-derived activated carbons (ACs) have served as effective adsorbents for water treatment, owing to their inherent porosity and expansive surface area. Nanocomposites have emerged as a means to enhance the absorption properties of ACs, surpassing conventional AC performance.

Knowledge, Attitude, and Barriers Toward Deceased Organ Donation Among Health Care Professionals and Medical Students in Southern Saudi Arabia: A Cross-Sectional Study.

Objectives: Knowledge and attitude of health care professionals and medical students are crucial to promoting positive outcomes of organ donation. This study aimed to evaluate knowledge and attitudes of health care professionals and medical students on organ donation in Southern Saudi Arabia.

Materials And Methods: We conducted a cross-sectional study of consented tertiary hospital health care professionals (n = 200) (group A) and medical students (n = 200) (group B) in Southern Saudi Arabia from December 2022 to April 2023.

Anterior segment optical coherence tomography meibography compared with keratograph meibography.

Purpose: The aim of this study was to determine the feasibility of using readily accessible technology, anterior segment optical coherence tomography (AS-OCT), to detect and grade meibomian gland dropout and examine its interchangeability with the Oculus Keratograph 5M (K5M).

Methods: A total of 30 participants (30 eyes) with a median age of 21 (range = 19-28 years) were recruited. Meibography was performed using two commercially available imaging devices to look at the structure of the meibomian glands and grade them subjectively in real time, and image analysis was used to quantify meibomian gland loss objectively.

Facile one pot microwave-assisted green synthesis of FeO/Ag nanocomposites by phytoreduction: Potential application as sunlight-driven photocatalyst, antibacterial and anticancer agent.

Herein, we report a one-pot microwave assisted method to prepare an efficient FeO/Ag nanocomposites (NCs) using Aloe vera (A. vera) gel extract as a mild, safe, renewable and active stabilizer without any harmful reagent. The advanced characterization techniques including XRD, FT-IR, UV-DRS, PL, TGA, SEM-EDX, TEM, DLS, Elemental mapping, VSM and BET were applied to analyze the morphology and structure of the prepared FeO/Ag NCs.

Tumor grading of soft tissue sarcomas using MRI-based radiomics.

Background: Treatment decisions for multimodal therapy in soft tissue sarcoma (STS) patients greatly depend on the differentiation between low-grade and high-grade tumors. We developed MRI-based radiomics grading models for the differentiation between low-grade (G1) and high-grade (G2/G3) STS.

Methods: The study was registered at ClinicalTrials.
