The Antioxidant And Antimicrobial Activities Of Cornsilk Extract Encapsulated In Polysaccharide Nanoparticles, Maryam Mady
The Antioxidant And Antimicrobial Activities Of Cornsilk Extract Encapsulated In Polysaccharide Nanoparticles, Maryam Mady
Theses and Dissertations
Corn silk possess antibacterial and antioxidant activities due to its phenolic compounds but they are of low bioavailability that requires some innovative techniques to develop such active ingredients in a safe and less toxic manner. Accordingly, silk extract SE was encapsulated in chitosan nanoparticles CS NPs, which is a natural and abundant polymer derived from chitin. Among 15 experimental trials via design expert software, the optimum formula of SE x\CS NPs was prepared at 800 rpm, 5hrs. on magnetic stirrer, and by CS: TPP ratio was 2.5:1. Then SEM showed the majority of particles size diameter in the range of …
Nebulizer-Based Systems To Improve Pharmaceutical Aerosol Delivery To The Lungs, Benjamin M. Spence
Nebulizer-Based Systems To Improve Pharmaceutical Aerosol Delivery To The Lungs, Benjamin M. Spence
Theses and Dissertations
Combining vibrating mesh nebulizers with additional new technologies leads to substantial improvements in pharmaceutical aerosol delivery to the lungs across therapeutic administration methods. In this dissertation, streamlined components, aerosol administration synchronization, and/or Excipient Enhanced Growth (EEG) technologies were utilized to develop and test several novel devices and aerosol delivery systems. The first focus of this work was to improve the poor delivery efficiency, e.g., 3.6% of nominal dose (Dugernier et al. 2017), of aerosolized medication administration to adult human subjects concurrent with high flow nasal cannula (HFNC) therapy, a form of continuous-flow non-invasive ventilation (NIV). The developed Low-Volume Mixer-Heater (LVMH) …
