The Use Of Nanoparticles And Electrospun Fibers For Intravaginal Delivery To Treat Viral And Bacterial Infections And Electrophysiological Measurements Of Synthetic Chloride Channels., Farnaz Minooei
Electronic Theses and Dissertations
Female reproductive viral and bacterial infections affect millions of women worldwide. Given the diversity and magnitude of these unmet reproductive health challenges, topical administration of antiretrovirals (ARVs) and antibiotics have emerged as promising approaches to maintain and restore reproductive health. However, currently available intravaginal dosage forms often suffer from low user adherence and the need for frequent, daily administration to achieve therapeutic effect. To address these challenges, the broad goal of this research was to focus on the development of new localized nanoparticle (NP) and electrospun fiber dosage forms to prolong the delivery and enhance the efficacy of active agents …
Polymeric Nanoparticles As An Antioxidant Delivery System For Age-Related Eye Disease, Sean M. Swetledge
Polymeric Nanoparticles As An Antioxidant Delivery System For Age-Related Eye Disease, Sean M. Swetledge
LSU Doctoral Dissertations
Advantages of polymeric nanoparticles as ocular drug delivery systems include controlled release, enhanced drug stability and bioavailability, and specific tissue targeting. Nanoparticle properties such as hydrophobicity, size, and charge, mucoadhesion, as well as administration route and suspension media affect their ability to overcome ocular barriers and distribute in the eye, and must be carefully designed for specific target tissues and ocular diseases. A review was conducted to serve as a guide to optimizing polymeric nanoparticle delivery systems for ocular drug delivery by discussing the effects of nanoparticle composition and administration method on their ocular penetration, distribution, elimination, toxicity, and efficacy, …
Thermoresponsive Nanogels Based On Different Polymeric Moieties For Biomedical Applications, Sobhan Ghaeini-Hesaroeiye, Hossein Razmi Bagtash, Soheil Boddohi, Ebrahim Vasheghani-Farahani, Esmaiel Jabbari
Thermoresponsive Nanogels Based On Different Polymeric Moieties For Biomedical Applications, Sobhan Ghaeini-Hesaroeiye, Hossein Razmi Bagtash, Soheil Boddohi, Ebrahim Vasheghani-Farahani, Esmaiel Jabbari

Nanogels, or nanostructured hydrogels, are one of the most interesting materials in biomedical engineering. Nanogels are widely used in medical applications, such as in cancer therapy, targeted delivery of proteins, genes and DNAs, and scaffolds in tissue regeneration. One salient feature of nanogels is their tunable responsiveness to external stimuli. In this review, thermosensitive nanogels are discussed, with a focus on moieties in their chemical structure which are responsible for thermosensitivity. These thermosensitive moieties can be classified into four groups, namely, polymers bearing amide groups, ether groups, vinyl ether groups and hydrophilic polymers bearing hydrophobic groups. These novel thermoresponsive nanogels …

Pilot Study Exploring The Effect Of Targeted Cox-2 Inhibition In Macrophages Responding To Neuronal Injury; Promoting Enhanced Axonal Regeneration, Alyssa Brauckmann
Pilot Study Exploring The Effect Of Targeted Cox-2 Inhibition In Macrophages Responding To Neuronal Injury; Promoting Enhanced Axonal Regeneration, Alyssa Brauckmann
Electronic Theses and Dissertations
Celecoxib nanoemulsion (CXB-NE) has been developed as a macrophage targeted analgesics by Dr. Janjic and her team at Duquesne University, (Janjic et al, 2018; Liu et al, 2020; Saleem et al, 2019b; Vasudeva et al, 2014). The CXB-NE nanoemulsion carrying a Nonsteroidal Anti-inflammatory (NSAID) inhibitor of COX-2 activity result in a reduction in PGE2 expression in macrophages. Using CXB-NE in rats that have peripheral nerve injury constricting the sciatic nerve relieves hypersensitivity, a pain-like behavior. The treatment also decreases inflammation associated with this chronic constriction injury (Janjic et al, 2018; Saleem et al, 2019b; Stevens et al, 2019). In this …
Preparation Of Intra-Articular Drug Delivery Systems For The Treatment Of Osteoarthritis, Ian Villamagna
Preparation Of Intra-Articular Drug Delivery Systems For The Treatment Of Osteoarthritis, Ian Villamagna
Electronic Thesis and Dissertation Repository
Osteoarthritis (OA) is a degenerative disease of the articular joints that affects over 240 million people globally. Despite its overwhelming prevalence, there is no disease modifying agent currently available to treat the disease, and many treatment options remain palliative in nature. Potentially effective treatments for OA are limited by probable systemic side effects. Intra-articular drug delivery systems present a new opportunity for the treatment of OA; encapsulated therapeutics can be injected directly into the joint, at the area of injury, thereby bypassing systemic administration and diminishing the chance for side effects. This thesis describes the research and development of novel …
Surface Modification Of Titanium For Orthopedic And Drug Delivery Applications, Prantik Roy Chowdhury
Surface Modification Of Titanium For Orthopedic And Drug Delivery Applications, Prantik Roy Chowdhury
Graduate Research Theses & Dissertations
Titanium is one of the most attractive metal used in orthopedic and drug delivery applications because of its excellent mechanical properties, biocompatibility and high corrosion resistance. However, due to its bio-inertness, fibrous tissue forms between the bone and implant which causes loosening of implant. Surface modification can play an important role to enhance interaction between implant and the surrounding tissues which reduces the implant failure. The aim of this study is to a) incorporate magnesium (Mg) into modified titanium surface by different deposition methods for bone-implant interaction, b) modify the surface of titanium by alkali treatment, and c) investigate the …
