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) …

Determination Of Sugars, Amino Acids, Ph And Alcohol In Bamboo Beverage From Southern Highlands, Tanzania, Lilian D Kaale

Tanzania Journal of Science

The amounts of sugars and amino acids play significant roles in defining the fermentation process and quantifying the alcohol levels in beverages, while pH affects the biological stability, colour, oxidation rate, and protein stability of alcoholic beverages. This study investigated the sugar content, amino acids, alcohol levels, and pH of bamboo beverage from Tanzania's southern highlands. During storage, the sugars significantly decreased (p < 0.05), especially when kept at room temperature from 52.96 to 0.00 (source 1), 53.35 to 0.00 (source 2) and 53.57 to 0.00 (source 3) g/L for fructose, from 47.93 to 14.78 (source 1), 47.23 to 14.91 (source 2) and 47.61 to 14.77 (source 3) g/L for glucose, and from 0.40 to 0.00 (source 1), 0.36 to 0.00 (source 2) and 0.37 to 0.00 (source 3) g/L for sucrose after six days of storage. A total of 15 amino acids were determined from the bamboo beverage with tyrosine being the most prevalent (597.68 mg/L for source 1, 599.44 mg/L for source 2 and 597.83 mg/L for source 3), followed by valine (261.13 mg/L for source 1, 261.24 mg/L for source 2 and 262.54 mg/L for source 3), threonine (76.69 mg/L for source 1, 76.91 mg/L for source 2 and 77.13 mg/L for source 3), and serine (66.37 mg/L for source 1, 67.23 mg/L for source 2 and 66.68 mg/L for source 3). After six days of storage at room temperature, there was a significant decrease in pH from 4.04 to 3.63. Alcohol content ranged from 3.11 to 9.05% v/v at the room temperature storage. These results might facilitate the optimal use of bamboo beverages, which have been neglected due to lack of scientific information such as amino acid and sugar levels. Keywords:    Bamboo beverage, ulanzi, amino acids, sugars, alcohol content.

Fool Me Once: Characterizing The Response Of Notophthalmus Viridescens To Multiple Exposures Of Batrachochytrium Salamandrivorans, Julia A. Mccartney

Graduate Masters Theses

The repertoire of defenses a host may use against a pathogen is often thought of in the context of innate and adaptive immunity. However, the role of host symbionts such as the microbiome are being examined potentially as part of an individual’s defense against disease. Chytridiomycosis, caused by the fungal pathogens Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal), is characterized by an infection of the skin often leading to osmotic imbalance and mortality, and has resulted in losses in global amphibian biodiversity. Understanding what may influence the development of resistance to or tolerance of infection is critical to developing prevention …

Host-Pathogen Interactions In A Changing World: Microbes, Mucosal Defenses, And Multiple Hosts, Brandon C. Labumbard

Graduate Doctoral Dissertations

As fungal diseases continue to emerge, research increasingly focuses on host-microbiome interactions and links to disease. Certain skin-associated microbes may benefit hosts by protecting them from invading pathogens. Seasonal changes in the host environment can also result in shifts in the microbial community and pathogen virulence – potentially influencing disease dynamics. I investigated how cutaneous microbial communities differ across hosts, seasons, and Batrachochytrium dendrobatidis (Bd) infection status by sequencing the microbial communities of 1,100 leopard frogs at five locations across the US. Percent anti-Bd function varied seasonally and with Bd infection status. Bacterial communities also varied across locations and time. …

Quantifying Life History Energetics Of An Oviparous Elasmobranch Subject To Future Warming Water, Carolyn R. Wheeler

Graduate Doctoral Dissertations

Marine ectothermic fishes – fishes that do not regulate internal body temperature independent from the water temperature – are some of the most vulnerable organisms to rapid and alarming increases in environmental temperature occurring due to climate change mediated-ocean warming. For tropical fish species that live near their thermal maxima, this warming could be of grave consequence to individuals, populations, and whole marine ecosystems. Certain key life stages such as embryos and reproducing adults may be particularly vulnerable to warming given the excess energetic costs of these life stages, which may disallow compensation for extreme changes in temperature. One taxonomic …

Cancer metastasis is a major cause of cancer-related mortality. Strategies to reduce metastases are needed especially in lung cancer, the most common cause of cancer mortality. We previously reported increased ubiquitin-specific peptidase 18 (USP18) expression in lung and other cancers. Engineered reduction of USP18 expression repressed lung cancer growth and promoted apoptosis. This deubiquitinase (DUB) stabilized targeted proteins by removing the complex interferon-stimulated gene 15 (ISG15). This study explores if the loss of USP18 reduced lung cancer metastasis. USP18 knock-down in lung cancer cells was independently achieved using small hairpin RNAs (shRNAs) and small interfering RNAs (siRNAs). USP18 knock-down reduced …
