The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud
Open Access Theses
Attention-deficit/hyperactivity disorder (ADHD) is the most diagnosed behavioral disorder in children. It affects around 5% of children worldwide and 11% of children in the United States, with rates increasing. Pharmaceutical treatments, such as amphetamines and methylphenidates, are not effective for everyone and are known to have unwanted side effects. While the etiology of the disorder is not yet fully understood, there are clear genetic and environmental components. Nutritional insufficiencies have recently become a popular environmental risk factor under investigation. Essential fatty acids (EFA), omega-3 polyunsaturated fatty acids (PUFA) in particular, are needed for proper brain development and function. Our lab …
The Effects Of Heat Stress On Immunity In Laying Hens And Dairy Cattle, Rebecca Ann Strong
The Effects Of Heat Stress On Immunity In Laying Hens And Dairy Cattle, Rebecca Ann Strong
Open Access Theses
With the increase in global climate change and the population growth driving the high demand for additional food production, heat stress (HS) is a major concern in the livestock industry across all species. Animals experience HS when exposed to high environmental temperatures outside their thermal neutral zone. The level of the effects can vary due to the length and intensity of HS to which the animal is exposed to. In experiment one, laying hens with access to cooled perches during HS had a lower heterophil to lymphocyte ratio compared to the control hens after 4 h of acute heat stress, …
Iron Nutriture Following Roux-En-Y Gastric Bypass Surgery, Breanne N. Wright
Iron Nutriture Following Roux-En-Y Gastric Bypass Surgery, Breanne N. Wright
Open Access Theses
Roux-en-Y gastric bypass surgery (RYGB) is effective for weight loss, but is commonly associated with iron deficiency and its clinical manifestation, anemia. Diagnosing iron deficiency is complex because iron status depends on other nutrients; additionally, anemia following surgery is not specifically due to deficiency in iron, as it can be due to deficiencies in other nutrients including zinc, copper, vitamin B6, folate, and vitamin B 12. In patients who have undergone RYGB, our aims were to 1) conduct a comprehensive assessment of nutrients involved in iron homeostasis, 2) determine the contribution of dietary intake to iron deficiency, …
Efficacy Of Cleaning Method For Removal Of Exogenous Welding Fume Contamination From Nail Tissue Prior To Use As A Biomarker For Welding Fume Manganese Exposure, Jeffrey Corral Bainter
Efficacy Of Cleaning Method For Removal Of Exogenous Welding Fume Contamination From Nail Tissue Prior To Use As A Biomarker For Welding Fume Manganese Exposure, Jeffrey Corral Bainter
Open Access Theses
Nail tissue has been proposed as a biomarker for body burden of occupational exposure to manganese from welding fumes. Though recent studies have shown correlation between manganese exposure and both nail tissue concentration as well as concentrations in dopaminergic regions of the brain, concerns of the validity of nail tissue as a biomarker have arisen due to the potential for exogenous contamination of Mn to undermine the quantization of endogenous Mn in nail. Previous studies have used a cleaning method of 1% Triton X-100 surfactant plus sonication in order to attempt to remove exogenous welding fume contamination. Determination of the …
1,25-Dihydroxyvitamin D Alters Lipid Metabolism And Epithelialto- Mesenchymal Transition In Metastatic Epithelial Breast Cancer Cells, Alle Nicole Barnard
1,25-Dihydroxyvitamin D Alters Lipid Metabolism And Epithelialto- Mesenchymal Transition In Metastatic Epithelial Breast Cancer Cells, Alle Nicole Barnard
Open Access Theses
Evidence suggests that high vitamin D status (marked by serum 25-hydroxyvitamin D, 25(OH)2 D) is associated with a decreased risk of breast cancer. It has been established that 1,25-dihydroxyvitamin D (1,25(OH) 2 D) can alter glycolysis and the Krebs cycle of breast cancer cells (Jiang et al., 2010; Zheng et al., 2013) but little information is available on 1,25(OH) 2 D's alterations of lipid metabolism in breast cancer cells. Thus, the current research investigates if there was an effect of 1,25(OH) 2 D on proteins that regulate lipid metabolism in MCF10A, MCF10A-ras, MCF10CA1h, and MCF10CA1a epithelial breast cancer cells. While …
The Combined Effects Of Anthropogenic And Environmental Stressors On Fundulus Grandis Development, Christopher Jacob Klinkhamer
The Combined Effects Of Anthropogenic And Environmental Stressors On Fundulus Grandis Development, Christopher Jacob Klinkhamer
Open Access Theses
The 2010 Deepwater Horizon oil spill resulted in the release of ~ 5 million barrels of crude oil from the Macondo wellhead into the Gulf of Mexico. Oil from the spill was documented on 1,772km of shoreline with 847km of shoreline remaining oiled a year after the spill, and 687km of shoreline remaining oiled two years after the spill. Currently, there are few data available concerning long-term, sublethal effects associated with chronic exposure to crude oil in the Gulf of Mexico. In addition to the anthropogenic-induced stress of polycyclic aromatic hydrocarbon (PAH) exposure, aquatic organisms living in estuarial areas of …
Using The Microsoft Kinect To Assess Human Bimanual Coordination, Joshua James Liddy
Using The Microsoft Kinect To Assess Human Bimanual Coordination, Joshua James Liddy
Open Access Theses
Optical marker-based systems are the gold-standard for capturing three-dimensional (3D) human kinematics. However, these systems have various drawbacks including time consuming marker placement, soft tissue movement artifact, and are prohibitively expensive and non-portable. The Microsoft Kinect is an inexpensive, portable, depth camera that can be used to capture 3D human movement kinematics. Numerous investigations have assessed the Kinect's ability to capture postural control and gait, but to date, no study has evaluated it's capabilities for measuring spatiotemporal coordination. In order to investigate human coordination and coordination stability with the Kinect, a well-studied bimanual coordination paradigm (Kelso, 1984, Kelso; Scholz, & …
Investigation Into The Control Of Melittin Secondary Structure And Antimicrobial Activity, Zachary B. Molinets
Investigation Into The Control Of Melittin Secondary Structure And Antimicrobial Activity, Zachary B. Molinets
Open Access Theses
Antimicrobial resistance has been an exponentially growing problem since the discovery of antibiotics. Antibiotics have been misused for many years and this misuse has grown into a real problem for the medical community. While there are countless safeguards to prevent infection by a resistant strain of bacteria, there are still many plagued by it and must be treated with sometimes dangerous antibiotics. Melittin, along with many other peptides, contain potent antimicrobial properties, but are also toxic toward enthrocytes. The control of the secondary structure of peptides provides the key to adjusting their activity.
Clinical Investigation Of Plethysmographic Variability Index: A Derivative Index Of Pulse Oximetry In Anesthetized Dogs, Vaidehi V. Paranjape
Clinical Investigation Of Plethysmographic Variability Index: A Derivative Index Of Pulse Oximetry In Anesthetized Dogs, Vaidehi V. Paranjape
Open Access Theses
Plethysmographic Variability Index (PVI) is a derivative index of pulse oximetry that allows evaluating an individual's intravascular volume status. Perfusion Index (PI) represents the strength of pulse signal at the anatomic site of measurement from which PVI is calculated using changes in PI over respiratory cycles. Plethysmographic Variability Index has been used to detect hypovolemia and predict fluid responsiveness in mechanically ventilated human patients however, fewer studies are available in spontaneously breathing patients. The use of PVI has not been explored extensively in dogs so far. The goals of this study were to establish a common range for PVI and …

Pharmaceuticals And Personal Care Products: Emerging Contaminants In Aquatic Ecosystems, Jenny E. Zenobio
Pharmaceuticals And Personal Care Products: Emerging Contaminants In Aquatic Ecosystems, Jenny E. Zenobio
Open Access Theses
In recent years, the presence of pharmaceuticals and personal care products (PPCPs) in aquatic systems has led to research on their fate and effects. PPCPs have been found in mixture in wastewater effluents, surface, ground, and drinking water at low concentrations from areas of intense urbanization. Although adverse effects to human health from the current environmental concentrations are unlikely, the impacts to ecological receptors are not clear. We performed field and laboratory studies to quantify and evaluate effects of PPCPs on fish. First, a field study was conducted at the Baca National Wildlife Refuge, Colorado (2010-2012) because a portion of …
