Actomyosin contraction powers the sealing of epithelial sheets during embryogenesis and wound closure; however, the mechanisms are poorly understood. After laser ablation wounding of Madin-Darby canine kidney cell monolayers, we observed distinct steps in wound closure from time-lapse images of myosin distribution during resealing. Immediately upon wounding, actin and myosin II regulatory light...

In this study we evaluated the performance of forward osmosis (FO) at the pilot scale to achieve simultaneous seawater desalination and wastewater reclamation. The investigation was performed with a commercial spiral wound FO membrane element for approximately 1300 h of continuous operation, processing 900,000 L of wastewater effluent and producing 10,000 L of purified water through a hybrid FO...

Reverse osmosis (RO) spiral wound membrane generation reached 93.5% in 2020, resulting 14,000 tons of used RO membranes being discarded annually into landfills, which is unprecedented. The current study aims to chemically convert the end-of-life membrane, followed by its performance evaluation and microbial removal efficiency on three different sources water, i.e., tap water (TW), integrated co...

This review article aimed to study chitosan as a material based in wound dressing preparation. The method this is the approximation method. articles were obtained from national and international journals such Scopus, PubMed, Google Scholar by using keywords "Chitosan", "Wound Healing", "Biomedical Application". inclusion criteria of are: books contains as, published last ten years, not article....

In this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. A polyamide spiral wound RO membrane followed by three filters as RO pretreatment (two activated carbon and one cartridge filter) and samples of Tehran refinery treated waste water have been used. The effect of operating conditions such as pressure differ...

Wound healing remains a clinical problem, with cases of atrophic, hypertrophic, or keloid scars. Three-dimensional scaffolds have been used to restore skin function, facilitating cell migration, adhesion, and proliferation. Collagen is the most common, presenting low antigenicity, decreased inflammation, replacement by autologous tissue. It as sheets/films, sponges, membranes, sprays, hydrogels...

Electrospun membranes of polycaprolactone are widely used for biomedical applications like wound dressings and tissue engineering scaffolds. It is important to sterilize this material using the most accepted method, the gamma irradiation. In this study, we have evaluated the sterilizability of electrospun polycaprolactone membranes with gamma radiation of varying doses. The irradiated materials...

The clinical application of the fetal membranes dates back to nearly a century. Their use has ranged from superficial skin dressings to surgical wound closure. The applications of the fetal membranes are constantly evolving, and key to this is the uncovering of multiple populations of stem and stem-like cells, each with unique properties that can be exploited for regenerative medicine. In addit...
