Synthesis And Functional Evaluation Of Peptide Modified Poly (Lactic-Co-Glycolic Acid) Nanoparticles To Inhibit Porphyromonas Gingivalis Biofilm Formation., Paridhi Kalia

Electronic Theses and Dissertations

Periodontal disease is an oral inflammatory disorder that afflicts roughly 46% of the adults in the U.S. Currently, treatment of periodontal disease involves the removal of plaque from the gingival pocket (with possible antibiotic treatment) and if necessary, gingival surgery. To our knowledge, no therapeutic approach exists that promotes host-biofilm homeostasis by limiting pathogen recolonization of the oral cavity after prophylaxis or treatment. The interaction of the pathogen Porphyromonas gingivalis with commensal streptococci is critical for initiation of periodontitis and represents a target for limiting P. gingivalis colonization of the oral cavity. Previous studies showed that a synthetic peptide …

Polymeric Nanocarriers For Treatment Of Melanoma And Genetically Modified Mesenchymal Stem Cells To Improve Outcome Of Islet Transplantation, Vaibhav Mundra

Theses & Dissertations

Melanoma is a lethal malignancy with limited treatment options for advanced metastatic stages. New targeted therapeutic options with discovery of BRAF and MEK inhibitors have shown significant survival benefit. Despite the recent progress, inefficient tumor accumulation and dose limiting systemic toxicity remains pressing challenges for treating metastatic melanoma and there is a need for drug delivery approach to improve therapeutic index of chemotherapeutics. Nanoparticle based drug delivery represents promising approach to enhance efficacy and reduce the dose limiting systemic toxicity. Nanoparticles can be formulated either by physical encapsulation of drugs or by covalent conjugation of drugs to the polymeric backbone. …

Conjugated Polymer Nanoparticles For Biological Labeling And Delivery, Eladio A. Mendez

FIU Electronic Theses and Dissertations

Cancer remains one of the world’s most devastating diseases, with more than 10 million new cases every year. However, traditional treatments have proven insufficient for successful medical management of cancer due to the chemotherapeutics’ difficulty in achieving therapeutic concentrations at the target site, non-specific cytotoxicity to normal tissues, and limited systemic circulation lifetime. Although, a concerted effort has been placed in developing and successfully employing nanoparticle(NP)-based drug delivery vehicles successfully mitigate the physiochemical and pharmacological limitations of chemotherapeutics, work towards controlling the subcellular fate of the carrier, and ultimately its payload, has been limited. Because efficient therapeutic action requires drug …

Nanoparticles are gaining immense popularity in the medical world, specifically in its use in drug delivery systems. The objective of this paper is to study, based on available published literature, how nanoparticles are utilized in drug delivery and more importantly to identify the potential toxic effects of nanoparticles. Based on textual research, it is clear that there are benefits to nanoparticle use, but new studies are showing that there are many potential hazards of nanoparticle-like particles. In order to fully determine the toxicity of the hundreds of types of nanoparticles, a clear method to categorize these particles is needed and …

Creation Of An Annotated Library On Fda Approved Nanomedicines, Marley R. Hodson, Tanin Izadi, Nastassja Lewinski Ph.D, Bridget T. Mcinnes Ph.D

Undergraduate Research Posters

Nanomedicine is a type of nanotechnology used in the medical field to limit the dosage amount and target drug delivery to specific cells. Nanomedicines that are approved and used tend to be extremely successful; however despite over a decade of research, only a limited number of nanomedicines have advanced for clinical use. A possible reason for the numerous nanomedicine failures is lack of easily accessible information and research on previous nanomedicines. In this project, we have compiled nanomedicine labeling information from the Drugs@FDA website. We have extracted phrases/sentences from labels relating to keywords on nanomaterial properties and drug profile characteristics. …
