United States Department of Agriculture Wildlife Services: Staff Publications

Duration of efficacy and prevalence of side-effects associated with GonaCon Immunocontraceptive Vaccine (GonaCon) in free-ranging female elk (Cervus elaphus) are unknown. In January 2008, we captured 120 mature female elk in Rocky Mountain National Park (CO, USA), determined pregnancy status, and randomly assigned them to treated (n=60; 1.5 mL of GonaCon) or control (n=60; 1.5 mL of saline) groups. During the following 3 winters we recaptured, collected blood for antibody concentrations, and euthanized 10–20 elk in each group. At necropsy, we determined pregnancy and collected tissues from organs associated with the hypothalamic–pituitary–gonadal axis. We …

Habitat Coupling In A Large Lake System: Delivery Of An Energy Subsidy By An Offshore Planktivore To The Nearshore Zone Of Lake Superior, Jason Stockwell, Daniel Yule, Thomas Hrabik, Michael Sierszen, Edmund Isaac

United States Geological Survey: Staff Publications

1. We hypothesised that the autumn spawning migration of Lake Superior cisco (Coregonus artedi) provides a resource subsidy, in the form of energy-rich cisco eggs, from the offshore pelagic to the nearshore benthic community over winter, when alternate prey production is likely to be low.

2. We tested this hypothesis using fish and macroinvertebrate surveys, fish population demographics, diet and stable isotope analyses, and bioenergetics modelling.

3. The benthic, congeneric lake whitefish (C. clupeaformis) was a clear beneficiary of cisco spawning. Cisco eggs represented 16% of lake whitefish annual consumption in terms of biomass, but 34% of energy (because of …

Potential Use Of Perennial Sunflower To Reduce Blackbird Damage To Sunflower, George M. Linz, Brent Hulke, Michael Kantar, Jeffrey Homan, Robert Stupar, Donald Wyse

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife Conservation Sunflower Plots (WCSP) have shown potential to reduce blackbird (Icteridae) damage in commercial sunflower. Also known as lure, decoy, or trap crops, WCSP are strategically placed food plots that provide an easily available and proximate food source that entices blackbirds away from valuable commercial crops. By providing an alternative food source, WCSP reduce direct damage to commercial fields, while also lowering indirect costs that producers incur attempting to prevent blackbird damage. However, cost inefficiencies have deterred widespread use of WCSP. Cost-benefit ratios of using WCSP would be greatly improved if a perennial sunflower were used instead of the …

Impact Of Whole Grains On The Gut Microbiota: The Next Frontier For Oats?, Devin J. Rose

Department of Nutrition and Health Sciences: Faculty Publications

The gut microbiota plays important roles in proper gut function and can contribute to or help prevent disease. Whole grains, including oats, constitute important sources of nutrients for the gut microbiota and contribute to a healthy gut microbiome. In particular, whole grains provide NSP and resistant starch, unsaturated TAG and complex lipids, and phenolics. The composition of these constituents is unique in oats compared with other whole grains. Therefore, oats may contribute distinctive effects on gut health relative to other grains. Studies designed to determine these effects may uncover new human-health benefits of oat consumption.

Processing Of Oats And The Impact Of Processing Operations On Nutrition And Health Benefits, Eric A. Decker, Devin J. Rose, Derek A. Stewart

Department of Nutrition and Health Sciences: Faculty Publications

Oats are a uniquely nutritious food as they contain an excellent lipid profile and high amounts of soluble fiber. However, an oat kernel is largely non-digestible and thus must be utilised in milled form to reap its nutritional benefits. Milling is made up of numerous steps, the most important being dehulling to expose the digestible groat, heat processing to inactivate enzymes that cause rancidity, and cutting, rolling or grinding to convert the groat into a product that can be used directly in oatmeal or can be used as a food ingredient in products such as bread, ready-to-eat breakfast cereals and …

We are concerned that readers of the IOC paper will be confused and misled by the poorly referenced statements and frank (and sometimes dangerous) errors in the paper. The IOC authors should publish a correction of these and other errors noted. Broadening research of low energy availability in other groups, such as the male athlete, athletes of diverse ethnicities and the disabled athlete may help to advance science and may one day warrant introduction of a specific term for whatever serious clinical sequelae of energy deficiency may be discovered in future research on men.

Department of Nutrition and Health Sciences: Faculty Publications

Objective

Lipid-soluble antioxidants are associated with a lower incidence for many chronic diseases of aging, possibly by preventing damage from chronic inflammation. In the current study, we compared serum levels of coenzyme Q₁₀ (CoQ₁₀), α-tocopherol, γ-tocopherol, and C-reactive protein (CRP) between adolescent girls and premenopausal women to assess changes from childhood to midlife.

Methods

Baseline serum CoQ₁₀, α-tocopherol, γ-tocopherol, and CRP levels were measured in 207 girls (13-19 years) and 183 premenopausal women (34-47 years) using standard methods and the two age groups were compared by t-test. The influence of age, body mass index (BMI) …

Egg Intake During Carbohydrate Restriction Alters Peripheral Blood Mononuclear Cell Inflammation And Cholesterol Homeostasis In Metabolic Syndrome, Catherine J. Andersen, Ji-Young Lee, Christopher N. Blesso, Timothy P. Carr, Maria Luz Fernandez

Department of Nutrition and Health Sciences: Faculty Publications

Egg yolk contains bioactive components that improve plasma inflammatory markers and HDL profiles in metabolic syndrome (MetS) under carbohydrate restriction. We further sought to determine whether egg yolk intake affects peripheral blood mononuclear cell (PBMC) inflammation and cholesterol homeostasis in MetS, as HDL and its associated lipid transporter ATP-binding cassette transporter A1 (ABCA1) reduce the inflammatory potential of leukocytes through modulation of cellular cholesterol content and distribution. Thirty-seven men and women classified with MetS consumed a moderate carbohydrate-restricted diet (25%–30% of energy) for 12 weeks, in addition to consuming either three whole eggs per day (EGG) or the equivalent amount …

Gene-Environment Interaction Of Body Mass Index And Apolipoprotein E Ε4 Allele On Cognitive Decline, Kumar B. Rajan, Kimberly A. Skarupski, Heather E. Rasmussen, Denis A. Evans

Department of Nutrition and Health Sciences: Faculty Publications

Genetic variation alone may not account for common chronic disease susceptibility. Rather, an interaction between genetic and environmental factors may clarify the underlying disease mechanism. Hence, we tested whether BMI modified the genetic association of the Apolipoprotein E (APOE) ε4 allele with cognitive decline. The data came from a longitudinal population-based sample of 4,055 participants interviewed at 3-year intervals from 1993 to 2012. Cognitive function was assessed using a standardized global cognitive score and BMI was assessed at baseline and classified as normal, overweight, and obese. There were 1,374 (34%) participants with the ε4 allele. In normal BMI participants, cognitive …

Evaluation Of Soilless Media Sensors For Managing Winter-Time Greenhouse Strawberry Production Using A Capmat System, George E. Meyer, Ellen T. Paparozzi, Stacy A. Adams, Diego Scacalossi Voltan

Department of Agronomy and Horticulture: Faculty Publications

It is important for a greenhouse strawberry grower to know that their capillary mat (CapMat™) fertigation system is working correctly and that plants are receiving the correct amounts of water and fertilizer. Pots with soilless mix are not expected to hold more than 70% water on a volumetric basis. Pots with less than 40% water content continuously are not supplied enough water and nutrients to the plants. Typically, pots located near the manifold distribution system get a little more water than those at the other locations, but water use will really vary according to the factors listed above as well …

Assessment Of Pediatric Primary Care Providers Behaviors And Procedures Regarding Pediatric Overweight And Obesity, Jessie N. Meiser

DNP Projects

CAPSTONE INTRODUCTION

Childhood overweight/obesity is a critical public health problem with devastating consequences. Many factors have combined to create the epidemic, and primary care providers can play an important role in addressing the problem by identifying overweight/obese children and encouraging them to engage in healthy behaviors. However, providers face a number of competing priorities making it difficult for them to provide these services effectively without outside support.

Obesity has reached an epidemic proportion in the nation’s youth. The Data Resource Center for Child and Adolescent Health (2011) found that 35.7% of children age 10 – 17 in Kentucky are overweight …

Theses and Dissertations--Plant and Soil Sciences

Ergovaline is produced by the endophyte Neotyphodium coenophialum (Morgan-Jones and Gams) in tall fescue (Schedonorus arundinacea (Schreb.) Dumort. = Festuca arundinacea Schreb.) and is blamed for a multitude of costly livestock disorders. Testing of pastures is common in both research and on farm situations. Since ergovaline is known to be unstable and affected by many variables, the objective of this study was to determine the effect of sample handling and storage on the stability of this compound. Homogeneous milled tall fescue sub-samples were analyzed for ergovaline concentration using HPLC after a range of sample handling procedures or storage. Ergovaline …

Switchgrass Yield And Quality With Multiple Fertilizer Applications And Harvest Dates, Thomas Clarkson Keene

Theses and Dissertations--Plant and Soil Sciences

Switchgrass (Panicum virgatum L.) is an important native warm-season grass for biomass and forage production in the U.S. This research determined the effect of fertilizer type (conventional, manure, and biosolids) and rate on switchgrass biomass yield and forage quality. Fertilizers were added at 0, 33, 67, 100, and 134 kg N ha^-1 on established stands of ‘Kanlow’ switchgrass in three northeastern Kentucky counties. Soils across sites ranged from recently cleared forestland (low pH, P, and K) to productive cropland (high pH, P and K). Stands were sampled for forage nutritive value in June, simulating a hay harvest. Nutritive …

C And N Cycling Dynamics And Microbial Community Composition In High Tunnel Production Systems, Kavita Lakshmi Mizin

Theses and Dissertations--Plant and Soil Sciences

Across the United States, high tunnels are used as a means of season extension and control over climatic variability in fruit and vegetable production. However, high tunnel systems are an intensive form of agricultural production which may compromise soil and crop quality over time. This study examined the effects of the varying environmental conditions, created in two types of tunnel system, movable and stationary, on the flow of nitrogen from amendment to plant and impact on crop and soil quality parameters. The way nutrients cycled through these systems was different and the nutrient treatments had no consistent effects on soil …

Evaluating The Effect Maturity On The Intake And Digestibility Of Switchgrass Hay Consumed By Beef Steers, David H. Davis

Theses and Dissertations--Plant and Soil Sciences

There has been increased interest in utilizing switchgrass (Panicum virgatum) as biomass. There are several challenges to developing this industry, and these have led to the potential use of switchgrass as hay for feeding beef cattle in Kentucky. The effect of increasing maturity on crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and nutritive values of switchgrass hay has been well documented, but few in vivo intake and digestibility trials have been conducted to assess this effect on animal performance when feeding beef cattle. Two in vivo intake and digestibility trials were conducted in 2011 …

Theses and Dissertations--Plant and Soil Sciences

To gain a better understanding of contaminating bacteria in bioethanol industry, we profiled the bacterial community structure in corn-based bioethanol fermentations and evaluated its correlation to environmental variables. Twenty-three batches of corn-mash sample were collected from six bioethanol facilities. The V4 region of the collective bacterial 16S rRNA genes was analyzed by Illumina Miseq sequencing to investigate the bacterial community structure. Non-metric multidimensional scaling (NMDS) ordination plots were constructed to visualize bacterial community structure groupings among different samples, as well as the effects of multiple environmental variables on community structure variation. Our results suggest that bacterial community structure is facility-specific, …

Effect Of Laser-Cut Slow-Flow Nipples On Preterm Feeding Performance, Katlyn Elizabeth Mcgrattan

MUSC Theses and Dissertations

Background: Dysphagia of prematurity is a highly prevalent condition that carries negative developmental, social, and financial implications. Although the modification of bottle nipple properties is a widely used treatment for dysphagia of prematurity, there have been a paucity of investigations examining the effect of this intervention on refined measures of feeding performance. Methods: Healthy preterm infants were evaluated for measures of milk ingestion and respiratory performance during oral intake on a laser-cut slow-flow and standard-flow nipple. Time to achieve hospital discharge milestones was recorded. Results: Few differences were observed in feeding performance between slow-flow and standard-flow nipples. Characteristics of respiration …
