Well-developed replacement heifers provide a central foundation for the continued success of the dairy industry. Emphasis on improving pre-weaned calf nutrition has predominated in the industry, but opportunities exist to improve post-weaning heifer nutrition and management. We aimed to evaluate common feed management strategies seen in the industry and their effects on growth, feed efficiency (G:F), and rumen development of calves from birth to 8 mo of age using pen- and individually-fed animal trials. Little information exists regarding post-weaning performance and rumen development of calves fed conventional or high planes of nutrition pre-weaning; therefore, we evaluated two milk replacer ...


The Effects Of Including Almonds In An Energy-Restricted Diet On Weight, Body Composition, Visceral Adipose Tissue, Blood Pressure And Cognitive Function, Jaapna Dhillon Aug 2016

The Effects Of Including Almonds In An Energy-Restricted Diet On Weight, Body Composition, Visceral Adipose Tissue, Blood Pressure And Cognitive Function, Jaapna Dhillon

Open Access Dissertations

Inclusion of almonds in an energy restricted diet has been reported to enhance or have no effect on weight loss. Their effects specifically on visceral fat stores during energy restriction have not been widely examined. Additionally, almond consumption has been associated with reduced blood pressure, but whether this is linked to or is independent of changes of body composition has not been examined. Moreover, almond consumption during energy restriction may be an effective strategy for reversing the negative effects of dieting on cognitive performance. The unique nutrient profile of almonds also has the potential to influence cognitive function post-prandially. The ...

Effect Of Hydration Status On Thermoregulatory Responses In Non-Obese And Obese Males, Matthew Tucker Aug 2016

Effect Of Hydration Status On Thermoregulatory Responses In Non-Obese And Obese Males, Matthew Tucker

Theses and Dissertations

During heat stress the human body thermoregulates via cutaneous vasodilation and sweating. Hypohydration can impair thermoregulatory responses that stem from the central nervous system (CNS), but it is unknown if impairments also occur post-synaptically in the microcirculation. Moreover, obese individuals may have impaired thermoregulation, possibly due to microvascular dysfunction. Purpose: The purpose of these studies was two-fold: 1) to determine if obese (OB) individuals exhibit impairments in thermoregulatory responses during exercise heat-stress (centrally-mediated) and intradermal infusion of vasoactive substances (peripherally-mediated) versus non-obese (N-OB), and 2) to determine if hypohydration subsequently affects these thermoregulatory responses differently between groups. Methods: Twenty-one healthy ...


Eucalyptus In Kenya; Impacts On Environment And Society, Brandy M. Garrett Kluthe Aug 2016

Eucalyptus In Kenya; Impacts On Environment And Society, Brandy M. Garrett Kluthe

Theses and Dissertations

Eucalyptus trees were introduced to Kenya a little over a century ago. European colonization along with the development of a railway system increased the demand for a fast growing wood source. The expansion of the tree across the fertile lands in Kenya raises concerns about the environmental impact on ecosystems where it has been introduced. These concerns include degraded soils, loss of water resources, co-introduction of ectomycorrhizal species, and allelopathy. Economic benefits to local landowners were also explored as well as the potential for large Eucalyptus woodlots to maximize the sequestration of CO₂ from the atmosphere. This was examined through ...

The Effect Of Protein Quantity And Quality At Breakfast On Energy Metabolism, Appetite And Metabolic Health, Brianna Lynne Neumann May 2016

The Effect Of Protein Quantity And Quality At Breakfast On Energy Metabolism, Appetite And Metabolic Health, Brianna Lynne Neumann

Theses and Dissertations

Obesity is a global health concern and, within the United States, the current obesity rate is 36% and projected to double within the next two decades. Obesity is linked to many chronic diseases such as cancer, heart disease and type 2 diabetes. In young females, weight gain (5-11 kg) between the ages of 20-30 years increases the risk of developing type 2 diabetes and cardiovascular disorders later in life. The cause of obesity is multifactorial in nature, however fundamentally weight gain occurs when energy intake is greater than energy expended (i.e. calories in > calories out). Therefore, identifying and validating ...

Immune Modulating Functions By Soypeptide Lunasin In Cancer Immunotherapy, Chun-Yu Tung May 2016

Immune Modulating Functions By Soypeptide Lunasin In Cancer Immunotherapy, Chun-Yu Tung

Open Access Dissertations

Chemotherapy is currently the mainstay of treatment for most cancer patients. Despite its efficacy in eliminating cancer cells, a high percentage of chemotherapy patients eventually relapse or suffer progression of the disease. Immunosurveillance is capable of recognizing and eliminating continuously arising transformed mutant cells, and thus cancer immunotherapy is one of the emerging therapeutic strategies that harnesses the power of the immune system to eradicate chemotherapy-resistant cancerous cells. However, the adverse side effects of chemotherapy impede the therapeutic effects of immunotherapy. Our previous studies demonstrate that lymphoma patients are refractory to clinical immunotherapy because of chemotherapy-induced immune dysfunction. In addition ...

The Effect Of Fluid Balance On Exercise Performance In The Heat, Yasuki Sekiguchi May 2016

The Effect Of Fluid Balance On Exercise Performance In The Heat, Yasuki Sekiguchi

Theses and Dissertations

Introduction: In dehydrated individuals thirst seems to disappear after ingestion of small amount of water before full rehydration. This phenomenon has been linked to oropharyngeal receptors. However, some researchers suggest that drinking to satisfy thirst is enough for optimal performance. It is well established that water deficit greater than 2% of body weight decreases exercise performance in the heat. No study has ever examined the effect hydration on exercise performance in the absence of thirst via oropharyngeal stimulation. Purpose: The purpose of this study is to examine the effect of dehydration on exercise performance and thermoregulation during exercise in the ...

Nutritional Deficiencies During The Harvest Season According To Household Consumption And Level Of Nutritional Knowledge: A Case Study Of Northern Mozambique, Maggie Jo Hansen

Theses and Dissertations

Mozambique is classified as a low income country, the lowest development classification defined by the World Bank. It is underdeveloped in food security, agricultural production, and nutritional status, and research shows its residents are not foreign to poverty and malnutrition. Low protein, starchy foods (maize, rice, wheat, cassava) comprise the majority of the Mozambican diet; these starchy foods are the most available for consumption. Although availability impacts diet, educational barriers may also threaten the knowledge of nutrition and perceptions of healthy foods. Illiteracy and lack of education are extreme challenges to disseminating nutritional education efforts in the rural Nampula region ...

Evaluation Of Rusle 2 To Estimate Soil Loss From Pastures, Stasha Katrina Balkissoon May 2016

Evaluation Of Rusle 2 To Estimate Soil Loss From Pastures, Stasha Katrina Balkissoon

Theses and Dissertations

The accurate estimation of soil erosion by the Revised Universal Soil Loss Equation version 2 (RUSLE2) is critical for several conservation assessments, least of which is its use in the Phosphorus Index (PI) to identify and rank the vulnerability of agricultural fields to phosphorus (P) runoff. Earlier versions of RUSLE reported a soil loss overestimation, which were revised to give RUSLE2, where biomass production in different climatic regions was more accurately represented. RUSLE version 2.0, which contains the new vegetative biomass production routine, was evaluated using two performance indices, the Nash Sutcliffe Efficiency Index (NSE) and Index of Agreement ...

Consonant Discrimination In The Inferior Colliculus Of Young And Aged Rats, Christopher S. Soverns Apr 2016

Consonant Discrimination In The Inferior Colliculus Of Young And Aged Rats, Christopher S. Soverns

Open Access Theses

Complex acoustic stimuli are thoroughly encoded and processed along the primary auditory pathway to give reliable and relevant information about the environment, and elucidating the neural coding mechanisms is essential to informing clinical attempts to combat auditory dysfuntion. Receiving a uniquely diverse set of ascending and descending inputs, the inferior colliculus (IC) is a site of intricate temporal processing. In this work, natural and modified human speech is used to investigate discrimination of voice onset time (VOT) in the spiking output of IC neurons. A template-matching classification model is proposed in which single stimulus presentation responses are correlated with aggregate ...


Failures In Adaptive Locomotion In Healthy Young Adults, Michel J. H. Heijnen Apr 2016

Failures In Adaptive Locomotion In Healthy Young Adults, Michel J. H. Heijnen

Open Access Dissertations

Young adults fall most frequently when walking, and trips account for 25% of these falls (Heijnen & Rietdyk, 2016). Common approaches to understanding tripping include the examination of behavior when a stationary obstacle is crossed successfully, or to deliberately trip the participant with a covert obstacle. However, these approaches do not establish the underlying cause of failure; examining inadvertent failures does, as this occurs most often in the field (Heijnen & Rietdyk, 2016). In order to identify the behavior that results in obstacle contact, this dissertation examined gait characteristics during inadvertent failures and manipulated the sensory information available to guide the limb trajectory. Manipulating the availability of sensory information is important to determine the information used to successfully guide the limbs, particularly the trail limb. Three experiments were conducted to systematically examine the role of visual and somatosensory information in young adults ...

Influence Of The 3d Microenvironment On Glioblastoma Migration And Drug Response, Ruth Marisol Herrera Perez

Open Access Dissertations

Glioblastoma (GBM) is a highly invasive brain cancer characterized by poor prognosis. Despite significant efforts by the basic and clinical research community our understanding of GBM progression and recurrence has been incremental. Improvements in therapeutic response have been dismal, and GBM continues to be the deadliest tumor of the central nervous system, with patient average survival rate of 12 months. Synergistic relationships that the tumor cells establish with the brain microenvironment have been proven fundamental for successful tumor progression and maintenance. Yet, many in vitro GBM studies are performed in formats that fail to recapitulate the most essential component of ...


Investigating The Role Of The Basic Helix-Loop-Helix Transcription Factor Mist1 In Pancreatic Diseases, Anju Karki Apr 2016

Investigating The Role Of The Basic Helix-Loop-Helix Transcription Factor Mist1 In Pancreatic Diseases, Anju Karki

Open Access Dissertations

Acinar cells of the exocrine pancreas are dedicated to synthesize, package and secrete immense quantities of pro-digestive enzymes to maintain proper metabolic homeostasis for the organism. Dysregulation of enzyme secretion in acinar cells can give rise to exocrine diseases including acute pancreatitis (AP), a disease that targets acinar cells, leading to acinar-ductal metaplasia (ADM), inflammation and fibrosis—events that can transition into the earliest stages of pancreatic ductal adenocarcinoma (PDAC). The focus of this thesis is to interrogate transcriptional regulatory networks that are susceptible to AP and the role that these networks play in acinar cell and exocrine pancreas responses ...
