Ion Exchange Zeolite Case Study
Evaluation of the effects of Ag exchanged zeolite nanocomposite on excisional wound healing in rats.
Introduction
Skin is often injured by wounding or physical trauma. Damages to skin initiate a series of complicated and well-orchestrated events of repair processes ending with complete reestablishment of the penetrate deep in the skin remain a major clinical problem because of morbidity associated with prolonged periods required for repair and regeneration of the injured tissue, bleeding, risk for infections and septicemias, keloids and scar formation 1. Although new therapeutic approaches for such a large and full thickness skin defect treatment have made progress, there is still need for better methods to enhance wound healing and recovery especially in severely wounded patients. One of the approaches for treating wounds is the use of biocompatible composites incorporated with antibacterial agent to improve wound healing and diminish the wound infection risk 2. Ion-exchange zeolite has gained attention due to its renewable nature, good biocompatibility and excellent

MCF-7 cells (9×103 cell/well) were incubated in 96-well plates each containing 200 ml of supplemented cell culture media for 24 h at 37°C and 5% Co2. The cells were divided in 4 groups in quadruplicates: blank and the Ag+-Zeolite/gelatin different concentrations of 0.1, 0.5, and 1 mg/ml were treated. After an incubation period of 24 h, the spent media were removed and the plate wells were washed with Phosphate buffered solution. Briefly, 50 IL of 2 mg/ml MTT and 150 IL culture medium were added to each well. The cells were incubated at 37 °C and 5% Co2 for 4 h. Then the media was discarded and dimethyl sulfoxide and Sorenson buffer was added to each well as solubilizer buffer. Finally, absorbance was read using an ELISA plate reader (BioTeck, Bad Friedrichshall, Germany) at 570 nm

    The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4, 0.8, 1.2, 1.6, 2.0 mg/ml of bovine serum were used to determine absorbance with a spectrophotometer. Two additional samples were made; one was blank and the other was for the specific homogenate sample. Then 3 microliters of bradford assay reagent, which indicates the amount of protein present by color, was added to all samples. The spectrophotometer was zeroed at 595 nm. A standard curve was made with the different absorbencies and concentrations. After the linear equation was formed, the unknown sample concentration was determined using the standard curve equation. A Gel Electrophoresis was used to perform a qualitative analysis. The use of 5 microliters of the homogenate was heated to 80 degrees Celsius. Then the homogenate was transferred to a 2-microliter-protein gel sample buffer. Samples loaded on to the gel was run at 100 v and stained with comassie blue; observations were made next lab.

    Ion exchange is the process in which materials exchange one ion for another, hold it temporarily, and release it to a regenerating solution. These materials are widely used to treat raw water supplies that contain dissolved salts. Today, the most commonly used material is an ion exchange resin. Resins are plastic beads to which a favorable ion has been chemically attached which can be exchanged for unwanted ions dissolved in the raw in the water supply. Once the resin has given up or exchanged most of its favorable ions, it is said to be exhausted and needs to be regenerated by coming in contact with a strong solution of ions called the regenerant.…

    Often times the management of chronic wounds can become challenging for clinicians. In the article by Sibbald et al (1) they emphasize that wound healing should be achieved through an interprofessional team approach where the focus is holistic, focusing not only on the patient’s wound but on the patient as a whole. Once the cause of the wound is identified, the wound can be classified into three categories: healable, maintenance and non healable (1). Referring to the wound bed preparation paradigm discussed in Sibbald et al (2) I will discuss a management approach for each wound category.…

    The aim of topical antimicrobial treatment is to control microbial colonization and their consequent proliferation. Today, silver sulfadiazine is the most widely used topical antimicrobial for burn treatment. Silver sulfadiazine has numerous clinical advantages, including a broad antimicrobial spectrum and low toxicity. Silver sulfadiazine has in vitro activity against many burn wound pathogens including Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Klebsiella, Proterus, Enterobacteriaceae and Candida albicans. The frequency of resistance development with silver sulfadiazine is considerably lower than with other antimicrobials. So in the majority of burn patients the drug of preference for prophylaxis is silver sulfadiazine…
