Development Of C5ar-Targeted Nanoparticles For Delivery Of Vaccines, Shailendra Bharadwaj Tallapaka Venkata Sesha

Theses & Dissertations

Since the early attempts of Benjamin Jesty at inducing immunity against smallpox and the pioneering work of Edward Jenner, vaccination has been, and continues to remain, the principal method of protection from diseases. However, most of the successful vaccines have been against pathogens that do not have major mechanisms to evade the immune system. So far, many life-threatening diseases like hepatitis C, HIV infection, malaria etc., have been resistant to existing vaccination strategies. Thus, there is an urgent need to develop new vaccination strategies that can generate long-lived protective immunity against such pathogens.

The purpose of this thesis is to …

An Investigation Into Formulation And Therapeutic Effectiveness Of Nanoparticle Drug Delivery For Select Pharmaceutical Agents, Dustin Cooper

Electronic Theses and Dissertations

Drug based nanoparticle (NP) formulations have gained considerable attention over the past decade for their use in various drug delivery systems. NPs have been shown to increase bioavailability, decrease side effects of highly toxic drugs, and prolong drug release. Furthermore, polymer based, biodegradable nanodelivery has become increasing popular in the field of NP formulation because of their high degree of compatibility and low rate of toxicity. Due to their popularity, commercially available polymers such as poly lactic acid (PLA), poly glycolic acid (PGA) and polylactic-co-glycolic acid (PLGA) are commonly used in the development and design of new nano based delivery …

Multifunctional Hydroxyapatite And Poly(D,L-Lactide-Co-Glycolide) Nanoparticles For The Local Delivery Of Cholecalciferol, Nenad Ignjatović, Vuk Uskoković, Zorica Ajduković, Dragan Uskoković

Cholecalciferol, vitamin D3, plays an important role in bone metabolism by regulating extracellular levels of calcium. Presented here is a study on the effects of the local delivery of cholecalciferol (D3) using nanoparticulate carriers composed of hydroxyapatite (HAp) and poly(D,L-lactide-co-glycolide) (PLGA). Multifunctional nanoparticulate HAp-based powders were prepared for the purpose of: (a) either fast or sustained, local delivery of cholecalciferol, and (b) the secondary, osteoconductive and defect-filling effect of the carrier itself. Two types of HAp-based powders with particles of narrowly dispersed sizes in the nano range were prepared and tested in this study: HAp nanoparticles as direct cholecalciferol delivery …
