Enhancement of the Functional Performance of Cotton and Polyester Fabrics upon Treatment with Polymeric Materials Having Different Functional Groups in the Presence of Different Metal Nanoparticles.

This work examined the functional properties of three different treated fabrics, cotton, polyester, and cotton/polyester, with different polymeric materials (polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), or chitosan) in the presence and absence of two synthesized metal nanoparticles to impart and enhance fabric properties. Both metal nanoparticles (silver nanoparticle (AgNPs) and Zinc oxide nanoparticles (ZnONPs)) were synthesized using Leaves and characterized using different techniques. The different treated fabrics were dyed with Reactive Dye (Syozol red k-3BS) and evaluated for their color strength, fastness properties, ultraviolet protection, antimicrobial activity, and mechanical properties.

Functional Recellularization of Acellular Rat Liver Scaffold by Induced Pluripotent Stem Cells: Molecular Evidence for Wnt/B-Catenin Upregulation.

Background: Liver transplantation remains the only viable therapy for liver failure but has a severely restricted utility. Here, we aimed to decellularize rat livers to form acellular 3D bio-scaffolds suitable for seeding with induced pluripotent cells (iPSCs) as a tool to investigate the role of Wnt/β-catenin signaling in liver development and generation.

Methods: Dissected rat livers were randomly divided into three groups: I (control); II (decellularized scaffolds) and III (recellularized scaffolds).

Postextubation Noninvasive Ventilation in Respiratory Distress Syndrome: A Randomized Controlled Trial.

Objective: Successful extubation and prevention of reintubation remain primary goals in neonatal ventilation. Our aim was to compare three modalities of postextubation respiratory support-noninvasive positive pressure ventilation (NIPPV), nasal bilevel positive airway pressure (N-BiPAP), and nasal continuous positive airway pressure (NCPAP)-using the RAM cannula in preterm neonates with respiratory distress syndrome (RDS). Our secondary aim was to define the predictors of successful extubation.

Loading of chitosan - Nano metal oxide hybrids onto cotton/polyester fabrics to impart permanent and effective multifunctions.

New and durable multifunctional properties of cotton/polyester blended fabrics were developed through loading of chitosan (Cs) and various metal oxide nanoparticles (MONPs) namely ZnO, TiO, and SiO onto fabric surface using citric acid/Sodium hypophosphite for ester-crosslinking and creating new anchoring and binding sites, COOH groups, onto the ester-crosslinked fabrics surface. The surface morphology and the presence of active ingredients (Cs & MONPs) onto selected - coated fabric samples were analyzed by SEM images and confirmed by EDS spectrums. The influence of various finishing formulations on some performance and functional properties such as wettability, antibacterial activity, UV-protection, self-cleaning, resiliency and durability to wash were studied.

Effectiveness of acupressure versus isometric exercise on pain, stiffness, and physical function in knee osteoarthritis female patients.

Osteoarthritis (OA) is the most common form of arthritis and a leading cause of disability in older adults. Conservative non-pharmacological strategies, particularly exercise, are recommended by clinical guidelines for its management. The aim of this study was to assess the effectiveness of acupressure versus isometric exercise on pain, stiffness, and physical function in knee OA female patients.
