Olfactory Enrichment In California Sea Lions (Zalophus Californianus), 2015 The University of Southern Mississippi
Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson
In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in their native ...

Wildlife In U.S. Cities: Managing Unwanted Animals, 2015 The Humane Society of the United States
Wildlife In U.S. Cities: Managing Unwanted Animals, John Hadidian
Wildlife, Conservation, and Endangered Species
Conflicts between people and wild animals in cities are undoubtedly as old as urban living itself. In the United States it is only of late, however, that many of the species now found in cities have come to live there. The increasing kind and number of human-wildlife conflicts in urbanizing environments makes it a priority that effective and humane means of conflict resolution be found. The urban public wants conflicts with wildlife resolved humanely, but needs to know what the alternative management approaches are, and what ethical standards should guide their use. This paper examines contemporary urban wildlife control in ...

Application Of Ichip To Grow “Uncultivable” Microorganisms And Its Impact On Antibiotic Discovery, 2015 Chapman University
Application Of Ichip To Grow “Uncultivable” Microorganisms And Its Impact On Antibiotic Discovery, Rinzhin T. Sherpa, Caretta J. Reese, Hamidreza Montazeri Aliabadi
Pharmacy Faculty Articles and Research
Purpose. Antibiotics have revolutionized modern medicine, allowing significant progress in healthcare and improvement in life expectancy. Development of antibiotic resistance by pathogenic bacteria is a natural phenomenon; however, the rate of antibiotic resistance emergence is increasing at an alarming rate, due to indiscriminate use of antibiotics in healthcare, agriculture and even everyday products. Traditionally, antibiotic discovery has been conducted by screening extracts of microorganisms for antimicrobial activity. However, this conventional source has been over-used to such an extent that it poses the risk of “running out” of new antibiotics. Aiming to increase access to a greater diversity of microorganisms, a ...
Physiological And Behavioural Responses To Noxious Stimuli In The Atlantic Cod (Gadus Morhua), 2015 University of Oslo
Physiological And Behavioural Responses To Noxious Stimuli In The Atlantic Cod (Gadus Morhua), Jared R. Eckroth, Øyvind Aas-Hansen, Lynne U. Sneddon, Helena Bichão, Kjell B. Døving
Animal Sentience, Intelligence, and Behavior
In the present study, our aim was to compare physiological and behavioural responses to different noxious stimuli to those of a standardized innocuous stimulus, to possibly identify aversive responses indicative of injury detection in a commercially important marine teleost fish, the Atlantic cod. Individual fish were administered with a noxious stimulus to the lip under short-term general anaesthesia (MS-222). The noxious treatments included injection of 0.1% or 2% acetic acid, 0.005% or 0.1% capsaicin, or piercing the lip with a commercial fishing hook. Counts of opercular beat rate (OBR) at 10, 30, 60, 90 and 120 min ...
Negative Skeletal Effects Of Locally Produced Adiponectin, 2015 Chapman University
Negative Skeletal Effects Of Locally Produced Adiponectin, Marcia J. Abbott, Theresa M. Roth, Linh Ho, Liping Wang, Dylan O'Carroll, Robert A. Nissenson
Health Sciences and Kinesiology Faculty Articles
Epidemiological studies show that high circulating levels of adiponectin are associated with low bone mineral density. The effect of adiponectin on skeletal homeostasis, on osteoblasts in particular, remains controversial. We investigated this issue using mice with adipocyte-specific over-expression of adiponectin (AdTg). MicroCT and histomorphometric analysis revealed decreases (15%) in fractional bone volume in AdTg mice at the proximal tibia with no changes at the distal femur. Cortical bone thickness at mid-shafts of the tibia and at the tibiofibular junction was reduced (3–4%) in AdTg mice. Dynamic histomorphometry at the proximal tibia in AdTg mice revealed inhibition of bone formation ...
Corn Fungicides: To Spray Or Not To Spray?, 2015 Iowa State University
Corn Fungicides: To Spray Or Not To Spray?, Alison E. Robertson, John M. Shriver
Integrated Crop Management News
Across the state of Iowa, much of the crop is reaching V5 to V6 and thoughts of an early fungicide application have probably crossed some people’s minds. Every year, we evaluate and compare registered fungicides applied at either V5 to V6, R1 alone, or At V5 to V6 plus R1 for foliar disease management and effects on yield. In 2014, we tested 8 products at 6 locations in Iowa (Table 1). A randomized complete block design with 4 replications was used. At each location, two non-sprayed checks were included.
Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, 2015 The University of Western Ontario
Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, Shahab Meshkibaf
Electronic Thesis and Dissertation Repository
The pleiotropic cytokine granulocyte-colony stimulatory factor (G-CSF) is mainly required for the generation of neutrophils, but its role in macrophage generation has also been reported. In addition, G-CSF is effective for the down-regulation of inflammatory cytokines and ameliorating gut disorders, such as colitis. However, the G-CSF function in macrophage generation and gut immunity remains unclear. The first focus of this thesis was to assess the role of G-CSF in macrophage generation and its contribution to gut immunity. G-CSF was found to promote the generation of Gr-1high/F4/80+ macrophages in macrophage (M)-CSF-treated bone marrow cells, most likely through suppressing ...
Soybean Seedling Damage: Is There An Interaction Between The Ilevo Seed Treatment And Pre-Emergence Herbicides?, Kiersten Wise, Daren S. Mueller, Yuba Kandel, Bryan Young, Bill Johnson, Travis Legleiter
Integrated Crop Management News
Farmers who were lucky enough to plant soybeans and spray pre-emergence herbicides in between rain events may now be seeing discolored or injured seedlings. Reports of fields with these issues are widespread across Indiana, Iowa, and surrounding areas, and many farmers and crop advisors are questioning if damage is more severe when pre-emergence herbicides are applied to fields that have been planted with seed treated with the new fluopyram fungicide seed treatment ILeVO.
The Effects Of A Caloric Restrictive Diet On Bone Mineral Density And Bone Strength In Male And Female Rats, Haley Folta
Student Research Day Abstracts and Posters
The purpose of this study was to determine the existence of sex differences following a 40% caloric restrictive diet and its impact on tibial bone mineral density (BMD) and bone strength between male and female rats. Thirty-two, six-week old Sprague Dawley rats (16 males and 16 females) were randomly divided into an ad libitum fed control group (MC, n=8 and FC, n=8) and a pair fed diet group placed on the 40% caloric restriction (MD, n=8 and FD, n=8) for a 6 week period. The caloric restrictive diet was equivalent to the normal fed diet in ...

Purpose: The purpose of this study was to determine the impact of a 20% and a 40% caloric restrictive diet on bone mineral density (BMD) and bone strength in male rats during the growth period. Methods: 32 male rats were randomly divided into: control groups (C20, n=8 and C40, n=8), a group fed the 20% caloric restrictive diet (D20, n=8), and a group fed the 40% caloric restrictive diet (D40, n=8). An animal in the caloric restrictive diet group was matched and pair fed with an animal in the control group for 6 weeks. Each caloric ...
Puffs And Tufts: A Comparison Of Trichodesmium Colony Formations And Nutrient Availability Across The North Atlantic Ocean Using Remote Sensing Methods, Marc Rosenfield
Student Research Day Abstracts and Posters
Trichodesmium, a genus of diazotrophic bacteria, has the capability and the population to produce a large percentage of the total oceanic N2-fixation. Though their population is known to be heavily dependent on two of the ocean’s largest limiting factors, phosphorus and iron concentrations, it is unknown what affect these factors have on the population. In this study two of the largest colony formations of Trichodesmium in the North Atlantic, tufts and puffs, are compared nutrient quality with respect to time and geographical location. Though very little nutrient in situ data was collected from the cruise, remote sensing data collected ...
Effects Of Human Recreational Activity On The Tameness Of Common Loons (Gavia Immer) In Northern Wisconsin, Seth Yund
Student Research Day Abstracts and Posters
The Common Loon (Gavia immer) is an aquatic diving bird that lives in freshwater habitats in Canada and the northern U.S.. Human activity on a loon’s resident lake may affect its fitness and behavior, yet few studies identify or quantify these effects. We modified existing techniques that measure escape distances in other species to measure tameness as the distance at which individual loons dove in response to human approach by canoe. Tameness was similar between pair members, suggesting that common lake conditions or the behavior of a mate might influence the behavior. Sex, size within sex, and human ...
Characterization And Investigation Of Fungi Inhabiting The Gastrointestinal Tract Of Healthy And Diseased Humans, 2015 University of Nebraska-Lincoln
Characterization And Investigation Of Fungi Inhabiting The Gastrointestinal Tract Of Healthy And Diseased Humans, Mallory J. Suhr
Dissertations & Theses in Food Science and Technology
Gastrointestinal microbiome studies have failed to include fungi in total community analyses. As a result, their diversity and function in the gut is poorly understood. Recent work has begun to uncover the role intestinal fungi play in diet, immune system development, interactions with other microorganisms in the gut, and pathogenesis of diseases. Advances in sequencing technologies allow for the ability to profile the fungal gut microbiome (“mycobiome”) in healthy and diseased states. This thesis explores the mycobiome in 1) healthy humans with a vegetarian diet and 2) pediatric small bowel transplant recipients that develop fungal bloodstream infections.
The gut mycobiome ...
Persister Cell Control Mechanisms In Uropathogenic Escherichia Coli, 2015 University of Rhode Island
Persister Cell Control Mechanisms In Uropathogenic Escherichia Coli, William H. Law Iii
Senior Honors Projects
Persister cells are a subpopulation of bacteria that demonstrate high tolerance to antibiotics, but revert to sensitivity after antibiotics are removed. The mechanism for induction of the persister cell state and antibiotic tolerance is not completely understood but likely occurs through the establishment of dormancy. Some of the suggested mechanisms for persister cell formation in Escherichia coli include: toxin-antitoxin systems, starvation, gene regulation by (p)ppGpp, and stochastic formation. In our study we examine the mechanisms behind persistence in the E. coli strain CFT073, a uropathogenic isolate, which forms elevated levels of persisters compared to the laboratory strain MG1655 ...

Examining Phage Infection Utilizing Mycobacterium Smegmatis, 2015 LaSalle University
Examining Phage Infection Utilizing Mycobacterium Smegmatis, Tanya L. Riddick
Bacteriophages, also known as phages, are viruses that are ubiquitous and survive and replicate within the host of the bacterial cell, Mycobacterium smegmatis. They are considered one of the most abundant organisms on earth (1031). Structurally, they are 100-200nm in size and consist of a protein encapsulated head that contains DNA or RNA, a tail sheath and tail fibers. This research consisted of examining phage infection, by re-isolating a novel phage, Tango. Tango was originally isolated genetically in 2013 by a previous ISBT student, Anna Maccarrone. The phage was sent to genetic sequencing but two phages were discovered, instead ...

Hiv-1 Non-Macrophage-Tropic R5 Envelope Glycoproteins Are Not More Tropic For Entry Into Primary Cd4+ T-Cells Than Envelopes Highly Adapted For Macrophages, Thomas A. Musich, Olivia O'Connell, Maria Paz Gonzalez-Perez, Cynthia A. Derdeyn, Paul J. Peters, Paul R. Clapham
Open Access Articles
BACKGROUND: Non-mac-tropic HIV-1 R5 viruses are predominantly transmitted and persist in immune tissue even in AIDS patients who carry highly mac-tropic variants in the brain. Non-mac-tropic R5 envelopes (Envs) require high CD4 levels for infection contrasting with highly mac-tropic Envs, which interact more efficiently with CD4 and mediate infection of macrophages that express low CD4. Non-mac-tropic R5 Envs predominantly target T-cells during transmission and in immune tissue where they must outcompete mac-tropic variants. Here, we investigated whether Env+ pseudoviruses bearing transmitted/founder (T/F), early and late disease non-mac-tropic R5 envelopes mediated more efficient infection of CD4+ T-cells compared to ...
