Characterization Of Molecular Communication Based On Cell Metabolism Through Mutual Information And Flux Balance Analysis, Zahmeeth Sayed Sakkaff
Characterization Of Molecular Communication Based On Cell Metabolism Through Mutual Information And Flux Balance Analysis, Zahmeeth Sayed Sakkaff
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Synthetic biology is providing novel tools to engineer cells and access the basis of their molecular information processing, including their communication channels based on chemical reactions and molecule exchange. Molecular communication is a discipline in communication engineering that studies these types of communications and ways to exploit them for novel purposes, such as the development of ubiquitous and heterogeneous communication networks to interconnect biological cells with nano and biotechnology-enabled devices, i.e., the Internet of Bio-Nano Things. One major problem in realizing these goals stands in the development of reliable techniques to control the engineered cells and their behavior from the …
Alginate Hydrogels As Three-Dimensional Scaffolds For In Vitro Culture Models Of Growth Plate Cartilage Development And Porcine Embryo Elongation, Taylor D. Laughlin
Alginate Hydrogels As Three-Dimensional Scaffolds For In Vitro Culture Models Of Growth Plate Cartilage Development And Porcine Embryo Elongation, Taylor D. Laughlin
Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research
The establishment of in vitro culture models utilizes tissue engineering principles to design functional mimics of in vivo environments in vitro. Advantages for the use of in vitro culture models include ethical alleviation of animal models for therapeutic testing, cost efficiency, and a greater ability to study specific mechanisms via a systematic, ground-up approach to development. In this thesis, alginate hydrogels are utilized in the development of in vitro culture models of porcine embryo elongation and growth plate cartilage development. First, the effect of scaffold and modifications to the scaffold were explored in both projects. In order to modulate …
Interaction Of Fibrinogen With Fibronectin: Purification And Characterization Of A Room Temperature-Stable Fibrinogen-Fibronectin Complex From Normal Human Plasma, Ayman E. Ismail
Department of Chemical and Biomolecular Engineering: Theses and Student Research
A fibrinogen-fibronectin complex (γγ’pdFI-pdFN) was purified from normal human plasma using a sequence of cryoprecipitation, ammonium sulfate fractionation, and DEAE Sepharose chromatography. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) under reducing condition showed both a 1:1 stoichiometric ratio of fibrinogen (FI) to fibronectin (FN) as well as a stoichiometric ratio of 1:1 of γg to gγ’. The γγ’pdFI-pdFN complex was non-covalent in nature as it was disrupted by affinity adsorption to Gelatin Sepharose where pdFN bound strongly and the disrupted γγ’pdFI fell through the chromatographic column. Surprisingly, the purified γγ’pdFI-pdFN complex was more broadly thermally stable than plasma FI (pdFI) …

The growth plate has an intricate architecture, and this architecture is necessary for directional growth of bones. Specifically, the cells align in longitudinal columns. As the growth plate expands with this pattern, the bone elongates with the same alignment pattern. The purpose of this research is to mimic this single celled, columnar alignment in vitro. In developing this alignment in vitro, this research will contribute to the overall study of growing growth for the development of improved therapeutic treatments and engineered tissues for transplants.

In the continued absence of an effective anti-HIV vaccine, approximately 2 million new HIV infections occur every year, with over 95% of these in developing countries. Calls have been made for the development of anti-HIV drugs that can be formulated for topical use to prevent HIV transmission during sexual intercourse. Because these drugs are principally destined for use in low-resource regions, achieving production costs that are as low as possible is an absolute requirement. 5P12-RANTES, an analog of the human chemokine protein RANTES/CCL5, is a highly potent HIV entry inhibitor which acts by achieving potent blockade of the principal HIV …
