Graduate Theses and Dissertations
In plants, reactive oxygen species (ROS) are generated as a byproduct of normal metabolism, as well as in response to adverse conditions such as light stress, extreme temperatures, and exposure to pests and pathogens. Singlet oxygen (1O2) is a ROS that is formed during photosynthesis in photosystem II (PSII) of the chloroplasts. Levels of 1O2 and other ROS are tightly controlled in healthy plants, but some studies suggest that levels of fatty acid desaturase (FAD) activity in Arabidopsis thaliana can influence constitutive and/or stress-responsive ROS accumulation. In this study, a luciferase-based reporter gene that is selectively stimulated by 1O2 (AAA-ATPase: …

Islet amyloid polypeptide (IAPP) also called amylin is an amyloid-forming protein; IAPP is a proteinaceous hormone that comprises 37 amino acid residues. It is secreted along with insulin from the pancreatic β-cells to help it regulate the uptake and removal of glucose in the bloodstream. IAPP has been observed in the amyloid deposits found in pancreatic β-cells of most patients suffering from type II diabetes mellitus. This research project aims at producing recombinant amylin peptide. To achieve this goal, we used the pBAD plasmid vector which we introduced into Escherichia coli to express the peptide. Although the vector was successfully …
Local Modulation And Measurement Of Macrophage-Derived Bioactive Proteins From Implanted Biomaterials In Rat, Geetika Bajpai
Local Modulation And Measurement Of Macrophage-Derived Bioactive Proteins From Implanted Biomaterials In Rat, Geetika Bajpai
Graduate Theses and Dissertations
Fibrosis around the implanted medical devices is a severe problem that can plague long-term device reliability. Activation of macrophage phenotype (macrophage polarization) has emerged as a new and possible means for reducing fibrosis in the fields of biomaterials and regenerative medicine. Macrophages are phagocytic cells that respond to microenvironmental cues that direct their phenotype. Macrophage activation has been widely studied in mouse and human in the context of tumor biology, yet little information is available regarding how macrophage activation could be used in a biomaterials context. Further, rats rather than mice are the common subjects in biomaterials experiments. A significant …

In order to spread infections, bacterial collagenases methodically unravel collagen fibril in tissues. Collagen is the most abundant protein in the body, and can be found in the skin, bone and cartilage [1]. Two collagenases, ColG and ColH, synergistically dismantle collagen fibrils by seeking different weak links in the collagen structure. The collagen-binding domain (CBD) of these collagenases binds to most vulnerable regions in collagen [8]. Without CBDs, collagen fibril cannot be degraded. Cells express collagen receptors in order to anchor themselves, which is a critical step in cell proliferation. Binding sites for some collagen receptors, such as integrin and …
