Design And Fabrication Of Tpms-Based Bone Scaffolds: A Cost-Effective Approach Using Plga-Nha And 3d-Printed Pva Molds, Yasser Ahmed

Theses and Dissertations

This thesis introduces a new cost-effective method for fabricating bone scaffolds from triply periodic minimal surface (TPMS) geometries—namely Gyroid and Diamond structure—using a poly(lactic-co-glycolic acid)-nanohydroxyapatite (PLGA-nHA) composite and 3D-printed polyvinyl alcohol (PVA) molds. Current TPMS scaffold fabrication techniques depend on costly laser-based techniques like selective laser sintering and thus remain inaccessible. Herein, we reveal a cost-effective and repeatable indirect approach via fused deposition modeling (FDM) for printing water-soluble PVA molds, which are then iteratively cast filled with a PLGA-nHA solution. The protocol was optimized through concentration modulation and controlled evaporation of the solvent for optimum infiltration and uniformity in the …

Hillslope Degradation: Coarse Sands May Move Faster But Fines Dominate Flux, Robert Chance

Theses and Dissertations

Hillslopes are one of the most pervasive landforms on Earth yet the details of the processes that drive their evolution are not completely understood. Excluding boulders, the majority of mass and volume in soil-mantled hillslopes is composed of sand-sized and finer grains. Understanding the transport rates and governing transport mechanisms of these grains is therefore key to advancing our knowledge of hillslope evolution.This research investigates sand-sized sediment transport through field experiments at 20 sites tracking surface sediment motion and 11 sites measuring depth-dependent transport. These empirical results are compared against outputs from a novel grain-based hillslope diffusion simulation (GBHDS), which …

Inorganic Arsenite [I-As (Iii)] Represses Human Renal Progenitor Cell Characteristics And Induces Neoplastic-Like Transformation, Md Ehsanul Haque

Theses and Dissertations

Studies on populations exposed to inorganic arsenic (iAs) have shown an association between this particular exposure and the development of chronic kidney disease (CKD) and renal cell carcinoma (RCC). However, there are few studies addressing how acute exposure of the human kidney to iAs might lead to long-term alterations that might lead to CKD or RCC. This study’s hypothesis is that renal exposure to iAs might alter the renal cells responsible for the repair and regeneration of nephrons damaged by iAs exposure or other renal toxicants. The kidney possesses a minority epithelial cell population that co-express PROM1 and CD24 that …

Mendoza-Santiesteban, Nicolás Cuenca, Frances Lefcort

Biology Faculty Publications

Familial dysautonomia (FD) is a rare genetic neurodevelopmental and neurodegenerative disorder. In addition to the autonomic and peripheral sensory neuropathies that challenge patient survival, one of the most debilitating symptoms affecting patients' quality of life is progressive blindness resulting from the steady loss of retinal ganglion cells (RGCs).Within the FD community, there is a concerted effort to develop treatments to prevent the loss of RGCs. However, the mechanisms underlying the death of RGCs are not well understood. To study the mechanisms underlying RGC death, Pax6-cre;Elp1loxp/loxp male and female mice and postmortem retinal tissue from an FD patient were used to …

Spectrometric Detection Of Microplastics In The Environment: A Novel Approach Using Hyperspectral Imaging System, Mansurat Abdulmalik Ali

Theses and Dissertations

Microplastics (MPs), defined as plastic particles ranging from 1 μm to 5 mm, have emerged as one of the significant environmental contaminants due to their widespread presence in terrestrial and aquatic ecosystems. MPs originate from primary sources, such as industrial pre-production pellets and microbeads in personal care products, or secondary sources, such as the breakdown of larger plastic particles. Their persistence in the environment is due to their resistance to degradation and capacity to transport toxic substances and pathogens. These characteristics raise concerns about their ecological impacts and potential entry into food chains, ultimately affecting human health. Despite extensive research …
