Naturally Derived Fibrous Scaffolds Containing Metabolic Factors For Bone Tissue Engineering, Apurva Limaye Dec 2022

Naturally Derived Fibrous Scaffolds Containing Metabolic Factors For Bone Tissue Engineering, Apurva Limaye

Dissertations

More than 500,000 bone grafting procedures are performed each year to treat bone defects, trauma, and non-unions. Current strategies, including autografts and allografts, face limitations that include donor site morbidity and poor integration, respectively. Treatments using the delivery of the growth factor, bone morphogenetic protein-2 (BMP2), result in ectopic bone formation and adverse effects at high doses. Tissue engineering strategies are utilized to combat these challenges. Natural biomaterials are commonly used as tissue engineering scaffolds due to their biocompatibility, biodegradability, and they can promote cellular function. However, animal-derived materials can have limitations in availability, lot to lot variability and potential …

Microplastics And Genetic Vectors Promoting The Dissemination Of Antimicrobial Resistance In Municipal Wastewater Treatment Processes, Ngoc Dung Pham

Dissertations

The spread of antimicrobial resistance in the environment and especially its transfer into human pathogens have emerged as global issues. Activated sludge units at municipal wastewater treatment plants are "hotspots" converging a multitude of contaminants, including antibiotics, antibiotic-resistant bacteria (ARB), human pathogens, and microplastics. The prevalence of antibiotics can induce stress response of sludge microbial communities and promote the development of new resistance mechanisms and transmission venues, through which the dissemination of antibiotic resistance genes (ARGs) arises as mediated by mobile genetic elements (MGEs). In this doctoral dissertation, the impacts of microplastics and genetic vectors (i.e., MGEs and bacterial hosts) …

Due Process Junior: Competent (Enough) For The Court, Tigan Woolson

Journal of Law and Health

There are many reports presenting expert policy recommendations, and a substantial volume of research supporting them, that detail what should shape and guide statutes for juvenile competency to stand trial. Ohio has adopted provisions consistent with some of these recommendations, which is better protection than relying on case law and the adult statutes, as some states have done. However, the Ohio statute should be considered a work in progress.

Since appeals courts are unlikely to provide meaningful review for the substance of a juvenile competency determination, the need for procedures for ensuring that the determination is initially made in a …
