Encapsulation And Controlled Release Of Rhu-Erythropoietin From Chitosan Biopolymer Nanoparticles, Cody Bulmer
Encapsulation And Controlled Release Of Rhu-Erythropoietin From Chitosan Biopolymer Nanoparticles, Cody Bulmer
Electronic Thesis and Dissertation Repository
The objective of this research project was to develop a drug delivery system for recombinant human erythropoietin (rHu-EPO), a glycoprotein hormone used in the treatment of renal anaemia and chemotherapy induced anaemia, using the biopolymer chitosan as the base component. Two types of chitosan nanoparticles were produced through ionotropic gelation using flush mixing with either tripolyphosphate (TPP) or carrageenan polymer. Chitosan-TPP and chitosan-carrageenan nanoparticles were generated under a variety of conditions to evaluate the effects of chitosan concentration, chitosan to anion mass ratio and solution pH on the nanoparticle characteristics of particle diameter, surface charge and particle size distribution. A …

Abdominal aortic aneurysms (AAAs) typically manifest as localized wall weakening and dilation of the infrarenal aorta, which grows gradually, and ultimately leads to fatal rupture. It is caused due to overexpression of proteolytic enzymes (matrix metalloproteases or MMPs) resulting into disruption of tissue structure, especially elastic matrix, which cannot be regenerated by adult vascular cells. On account of post-operative complications associated with their surgical repair, there is a critical need for developing non-surgical strategies for slowing and even regressing AAA growth. Recent studies in our laboratory have demonstrated that 1 ng/mL of transforming growth factor-β1 (TGF-β1) enhances regenerative repair by …
