Despite the popularity of eye tracking technology, there is little emphasis in literature concerning the development of benchmarks of aggregate …

Behavioral, Functional, And Shape Assessment For Temporomandibular Joint, Feng Wei

All Dissertations

Temporomandibular joint (TMJ) disorders affect over 10 million people in the US with an annual economic cost of more than $4 billion. Due to intriguing etiological factors of TMJ disorders, objective and accurate diagnosis is difficult and so is with the treatment. Consequently, there is the high recurrence rate. To make the situation even worse, many other types of diseases, including cancer, share symptoms and signs with TMJ disorders. Early non-invasive, objective, subject-specific and accurate diagnosis is vital because incorrect or delayed diagnosis can cause patients to miss optimal treatment times, increase unnecessary therapy expenses and even endanger patients’ lives. …

Evaluation Of Animal Manure-Based Compost As An Environmental Source Of Clostridium Difficile, Muthu Dharmasena

All Dissertations

The number of Clostridium difficile infection (CDI) cases associated with healthcare and community is increasing. Increased isolation of this pathogen from environmental samples of soil, water, livestock animals and their feces, and produce suggests its dissemination in the environment. Identification, molecular characterization, and revealing the relationship of those isolates with human pathogenicity would be very helpful in understanding the epidemiology of CDI. Livestock manure is a rich source of nutrients for the growth of many crops, and composted manure is widely used as a fertilizer in organic farming. Microbial activities increase the temperature of composting materials, providing sufficient heat to …

High Precision Fret To Study Bimolecular Dynamics With High Temporal Resolution, Junyan Ma

All Dissertations

Förster Resonance Energy Transfer (FRET) is a promising methodology which is used by researchers in determining structural information of biomolecules. Other methodologies such as X-ray diffraction, nuclear magnetic resonance (NMR) and electron microscopy (EM), and X-ray scattering (SAXS) and circular dichroism (CD) can only give snapshots of the functional conformers. In the applications of most cases, FRET can only be used to give a qualitative result such as “yes” or “no” pattern. In our lab, we are able to expand this ability by applying FRET to quantitatively determine the structure and dynamic information in the biological system with high accuracy. …

Neonatal Subventricular Zone Neural Stem Cells Release Extracellular Vesicles That Act As A Microglial Morphogen, Mary C. Morton, Victoria N. Neckles, Caitlin M. Seluzicki, Jennie C. Holmberg, David M. Feliciano

Publications

Subventricular zone (SVZ) neural stem cells (NSCs) are the cornerstone of the perinatal neurogenic niche. Microglia are immune cells of the nervous system that are enriched in the neonatal SVZ. Although microglia regulate NSCs, the extent to which this interaction is bi-directional is unclear. Extracellular vesicles (EVs) are cell-derived particles that encase miRNA and proteins. Here, we demonstrate that SVZ NSCs generate and release EVs. Neonatal electroporated fluorescent EV fusion proteins were released by NSCs and subsequently cleared from the SVZ. EVs were preferentially targeted to microglia. Small RNA sequencing identified miRNAs within the EVs that regulate microglia physiology and …

Towards A Better Understanding Of The Molecular Mechanisms Underlying Plant Development And Stress Response, Peipei Wu

All Dissertations

The spectacular array of diverse plant forms as well as the predominantly sessile life style of plants raises two questions that have been fascinating to scientists in the field of plant biology for many years: 1) how do plants develop to a specific size and shape? 2) how do plants respond to environmental stresses given its immobility?

Plant organ development to a specific size and shape is controlled by cell proliferation and cell expansion. While the cell proliferation process is extensively studied, the cell expansion process remains largely unknown, and can be affected by several factors, such as cell wall …

Accounting For Soil Inorganic Carbon In The Ecosystem Services Framework For United Nations Sustainable Development Goals, Garth Raymond Groshans

All Theses

Soil inorganic carbon (SIC) is currently not included in the list of key soil properties related to ecosystem services (e.g., provisioning, regulating, cultural, and supporting services). Soil inorganic carbon is a dynamic key soil property used in soil classification, taxonomy and fertility, therefore its inclusion in the framework of ecosystem services is important. With soils rapidly changing due to human use and climate change, the soil ecosystem services framework should not include only soil organic carbon (SOC), but SIC as well since it is of global importance to soil fertility and the long-term carbon cycle, especially in semiarid and arid …

Neonatal Growth Measurements, Umbilical Concentrations, And Differential Gene Expression In The Placenta Of Swine In Relation To Placental Efficiency, Shanice Katelin Krombeen

All Theses

Placental efficiency (PE) describes the relationship between placental and fetal weights and is defined as fetal weight divided by placental weight. Within pig litters, PE can vary drastically, resulting in similarly sized pigs associated with very different placenta, up to a 50% weight difference. However, the means enabling the smaller placenta to grow a similarly sized littermate is unknown. The main objectives of this study were to (1) determine the concentration of glucose and cortisol in venous umbilical blood of pigs at birth and evaluate if a relationship existed between concentration and PE, and (2) determine the expression level of …

Precision Agriculture Technology Development And Utilization For Hay Production, Perry Jonathan Loftis

All Theses

Mass flow sensor algorithms were developed for a hay yield monitoring system using ultrasonic sensors to measure windrow height. The algorithms indicated accuracies of 17.34% to 9.51%, with a wide tolerance to mounting positions. The developed mass flow algorithms were used in a nitrogen rate strip test on a 25 ac irrigated Tifton 85 bermudagrass field. Results suggested that yield, crude protein content and profit was maximized with the highest nitrogen rate only during the first harvest of 2017. All other harvest suggested a lower rate of nitrogen should be applied in order to maximize profit. A second method of …

Persistence Of Escherichia Coli O157:H7 And Listeria Monocytogenes On The Exterior Of Common Packaging Materials, Duleeka Prasadani Kuruwita Arachchige

All Theses

Acute gastroenteritis (AGE), a major cause of illness, results in 179 million AGE cases every year in the United States. AGE bacteria that have low-infectious dose include E. coli O157:H7 (<10-100 cells) and L. monocytogenes (<1000 cells). Because of their low-infectious dose and high environmental resistance, contaminated surfaces, such as the exterior surface of food packages, could be a source for disease transmission. Our aim was to determine the persistence of E. coli O157:H7 and L. monocytogenes on three packaging materials - oriented polyethylene terephthalate (OPET), oriented polypropylene (OPP), and nylon-6. Coupons (25 cm2) from each material were sterilized under ultraviolet light for 5 minutes. Spot and spread inoculation was done on treatment coupons with ca. 7 log CFU of a 3-strain-mixture of green fluorescent protein (GFP)-labeled E. coli O157:H7. All the coupons were incubated at Technical …

Interrelationships Between Carbohydrate Fractions, Starch Degradability, And Unsaturated Fatty Acids In The Rumen And The Effects On Milk Fat Depressing Conditions, Louisa E. Koch

All Dissertations

Diet-induced milk fat depression is a multifactorial disorder characterized by sustained reduction in milk fat. Feeding high amounts of starch and unsaturated fatty acids have been shown to reduce milk fat yield and concentration, and alter ruminal biohydrogenation. In addition, starch with high rates of degradability may lead to a decrease in ruminal pH and an increase in the outflow of ruminal biohydrogenation intermediates. It is possible that starch sources of high degradability could still be utilized in diets for the recovery of milk fat depression, provided the unsaturated fat level is reduced. Replacing a portion of the starch, especially …

Impacts Of Exposure To A High Concentrate Based Diet On Marbling Development In Beef Cattle, Brandon Michael Koch

All Dissertations

The value of a carcass is largely dependent on lipid deposition. The subcutaneous and visceral depots are often reported to develop and fill first. These depots also have little to no value, and often result in carcass price discounts. The intramuscular depot is well correlated with consumer palatability and carcass value. The ability to increase deposition of intramuscular lipid while minimizing the filling of low value fat depots provides ample opportunity to improve carcass value. Three studies were performed to investigate the ability to improve marbling deposition by altering the timing and duration of exposure to high concentrate diets. The …
