Algae-Based Feed Ingredient Protects Intestinal Health During Eimeria Challenge And Alters Systemic Immune Responses With Differential Outcomes Observed During Acute Feed Restriction, K. Fries-Craft, M. M. Meyer, Elizabeth A. Bobeck

Animal Science Publications

Compounds in microalgae-derived feed ingredients in poultry diets may improve intestinal physiology and immunity to protect against damage induced by physiological and pathogen challenges, but mechanisms are examined sparingly. The study objective was to evaluate changes to intestinal morphology, permeability, and systemic immunity in broilers fed a proprietary microalgae ingredient during 2 separate challenge studies. In study 1, two replicate 28 d battery cage trials used 200 Ross 308 broilers each (n = 400) fed a control diet ± 0.175% algae ingredient. Half of the birds were subjected to a 12 h feed restriction challenge and fluorescein isothiocyanate dextran (FITC-D) intestinal ...


Eradicating Zebra Mussels: What Works?, Elijah Davies 2021 Kennesaw State University

Eradicating Zebra Mussels: What Works?, Elijah Davies

Symposium of Student Scholars

The invasion of U.S lakes and rivers by the invasive species of zebra mussels called Dreissena polymorpha has caused catastrophic harm to the local ecosystem by reproducing and outcompeting native mussel species as well as harm to pipes leading into water sources by binding to surfaces and reproducing to the point that the mussels clog pipes. In addition, recreation areas must be closed due to the sharp shells making areas unusable. In the past, research has focused on individual molluscicides and their eradication of zebra mussels, as well as their effect on native flora and fauna. My research will ...


Anything For A Cheerio: Brown Capuchins (Sapajus [Cebus] Apella) Consistently Coordinate In An Assurance Game For Unequal Payoffs, Lauren M. Robinson, Mayte Martínez, Kelly L. Leverett, Mattea S. Rossettie, Bart J. Wilson, Sarah F. Brosnan 2021 University of Veterinary Medicine Vienna

Anything For A Cheerio: Brown Capuchins (Sapajus [Cebus] Apella) Consistently Coordinate In An Assurance Game For Unequal Payoffs, Lauren M. Robinson, Mayte Martínez, Kelly L. Leverett, Mattea S. Rossettie, Bart J. Wilson, Sarah F. Brosnan

ESI Publications

Unequal outcomes disrupt cooperation in some situations, but this has not been tested in the context of coordination in economic games. To explore this, we tested brown capuchins (Sapajus [Cebus] apella) on a manual version of the Stag Hunt (or Assurance) Game, in which individuals sequentially chose between two options, Stag or Hare, and were rewarded according to their choices and that of their partner. Typically, coordination on Stag results in an equal highest payout, whereas coordinating on Hare results in a guaranteed equal but lower payoff and uncoordinated play results in the lowest payoff when playing Stag. We varied ...


To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand 2021 University of Maine

To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand

Electronic Theses and Dissertations

Ever since the eighteenth century, experts have tried to tell farmers how to farm. The agricultural enlightenment in Europe marked the beginning of a long arc of new experts aiming to change agricultural knowledge and practice. This dissertation analyzes the pivotal period in the late nineteenth and early twentieth century in Germany and the United States when scientists, improvers, and market agents began to develop comprehensive ways to communicate agricultural innovation to farmers. In a functional approach to analyzing the negotiation of agricultural knowledge through its communication in things, words, and practices, this dissertation argues that the process of change ...

Livestock is an important commodity playing a major role in the global economy. Red meat plays an important role in human life, as it is a good source of animal protein and energy. The fatty acid content of beef has been shown to impact the eating experience and nutritional value of beef. Therefore, this study aimed to identify genomic regions which can account for genetic variation in meat fatty acid content. Genotypes imputed to the Illumina BovineHD 770K BeadChip were used in this study. Thirty-six 1-Mb genomic regions with a posterior probability of inclusion (PPI) greater than 0.90 were ...


Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino 2021 Missouri State University

Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino

MSU Graduate Theses

Recent insights into the pathological role of Nucleotide P2Y2 receptor suggest P2Y2R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y2R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y2R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y2 in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological ...

Animal Science Publications

Sow mortality, as the result of pelvic organ prolapse (POP), has been increasing in the last decade in the U.S. swine industry. The objective of this study was to identify potential biological markers associated with risk of POP in sows. We hypothesized that sows differing in perineal score (PS) from PS1–PS3 (PS1—a presumed low POP risk; PS2—a presumed moderate POP risk; and PS3—a presumed high POP risk) would differ in circulatory biomarkers of inflammation and hormonal profiles. On gestation week 15, 2,864 individual sows were assigned a PS, and subsequently, 1.0%, 2.7 ...


The Analysis Of Ginsenosides In Ginseng Garden Soil, Karina Marie Kaberi 2021 The University of Western Ontario

The Analysis Of Ginsenosides In Ginseng Garden Soil, Karina Marie Kaberi

Electronic Thesis and Dissertation Repository

American ginseng (Panax quinquefolius L.) produces natural products called ginsenosides. The biggest challenge Ontario commercial ginseng farmers face is ginseng replant disease. To understand the function of ginseng root exudates, ginsenoside accumulation and persistence over time were investigated. Currently, no reliable ginsenoside specific extraction method, characterizing the changes in soil chemistry exists. Ginsenoside extraction protocol optimization was required to determine how ginsenoside composition changed over time. Overall, protocol optimization resulted in a 30% increase in yield of ginsenosides compared to previous extraction protocols. In the ginseng gardens, ginsenoside accumulation occurs slowly and did not reach significantly measurable amounts until the ...

Flow Cytometry For Identification Of Prdm1-Eyfp Transgenic Mice, Kayla M. Hufford, Olyvia D. Weaver, Nicole M. Young, Aspen E. King, Gregory K. Dekrey

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

The goal of this study was to determine if flow cytometry could be used to identify transgene carrier mice [B6.Cg-Tg(Prdm1-EYFP)1Mnz/J] by their expression of the enhanced yellow fluorescent protein (eYFP) in peripheral blood lymphocytes. In these mice, eYFP expression is under the control of the Prdm1 gene promoter. Littermates were identified as being either wild type or transgene carriers using a polymerase chain reaction (PCR) analysis of tail tissue. Peripheral blood leukocytes were isolated from each of the mice, and both the percent and mean fluorescence intensity (MFI) were determined for eYFP expression by lymphocytes. We ...


Developmental Environment Shapes Honeybee Worker Response To Virus Infection, Alexander Walton, Amy L. Toth, Adam G. Dolezal 2021 Iowa State University

Developmental Environment Shapes Honeybee Worker Response To Virus Infection, Alexander Walton, Amy L. Toth, Adam G. Dolezal

Ecology, Evolution and Organismal Biology Publications

The consequences of early-life experiences are far reaching. In particular, the social and nutritional environments that developing animals experience can shape their adult phenotypes. In honeybees, larval nutrition determines the eventual social roles of adults as reproductive queens or sterile workers. However, little is known about the effects of developmental nutrition on important adult worker phenotypes such as disease resilience. In this study, we manipulated worker developmental nutrition in two distinct ways under semi-natural field conditions. In the first experiment, we restricted access to nutrition via social isolation by temporarily preventing alloparental care. In the second experiment, we altered the ...


21°C Is The Emerging Ideal Temperature For Kidney Preservation In The Presence Of Hydrogen Sulfide, Smriti Juriasingani 2021 The University of Western Ontario

21°C Is The Emerging Ideal Temperature For Kidney Preservation In The Presence Of Hydrogen Sulfide, Smriti Juriasingani

Electronic Thesis and Dissertation Repository

Kidney transplantation is the treatment of choice for patients with end-stage kidney disease. However, the shortage of transplantable kidneys has led to ever-increasing waiting lists. As a result, kidneys obtained via donation after cardiac death (DCD) are being used more frequently for transplantation. However, they exhibit poorer outcomes due to ischemia-reperfusion injury (IRI) and cold preservation methods, such as static cold storage (SCS). Supplementing cold preservation solutions with hydrogen sulfide donors, such as AP39, has been shown to improve renal IRI and graft outcomes, but the injury associated with cold preservation remains. This thesis evaluates the effect of subnormothermic kidney ...


Obesity Alters The Ovarian Proteomic Response To Zearalenone Exposure, M. Estefanía González-Alvarez, Bailey C. McGuire, Aileen F. Keating 2021 Iowa State University

Obesity Alters The Ovarian Proteomic Response To Zearalenone Exposure, M. Estefanía González-Alvarez, Bailey C. Mcguire, Aileen F. Keating

Animal Science Publications

Zearalenone (ZEN), a nonsteroidal estrogenic mycotoxin, is detrimental to female reproduction. Altered chemical biotransformation, depleted primordial follicles and a blunted genotoxicant response have been discovered in obese female ovaries, thus, this study investigated the hypothesis that obesity would enhance ovarian sensitivity to ZEN exposure. Seven-week-old female wild-type nonagouti KK.Cg-a/a mice (lean) and agouti lethal yellow KK.Cg-Ay/J mice (obese) received food and water ad libitum, and either saline or ZEN (40 μg/kg) per os for 15 days. Body and organ weights, and estrous cyclicity were recorded, and ovaries collected posteuthanasia for protein analysis. Body and liver ...

Evaluation Of Increased Fiber, Decreased Amino Acids, Or Decreased Electrolyte Balance As Dietary Approaches To Slow Finishing Pig Growth Rates, Emma T. Helm, John F. Patience, Matthew R. Romoser, Colin D. Johnson, Jason W. Ross, Nicholas K. Gabler

Animal Science Publications

In swine production, pig movement restrictions or packing plant closures may create the need to slow growth rates of finishing pigs to ensure they remain at a marketable body weight when packing plant access is restored. Although dietary formulations can be successful at slowing pig growth, precision is needed regarding how to best formulate diets to achieve growth rate reductions. Thus, the objective was to evaluate three dietary experimental approaches aimed at slowing growth rates in finishing pigs. These approaches consisted of either increasing neutral detergent fiber (NDF), reducing essential amino acids, or reducing the dietary electrolyte balance through the ...

Human blood innate lymphoid cells (ILCs), which include ILCs and natural killer (NK) cells, derive from a common CD117+ILC precursor (ILCP). Yet, the relationship among the ILC subsets remains unclear. Bulk and single cell RNA-Seq and ATAC-Seq showed that blood ILC subsets cluster into ILC2s, ILCPs, a mixed cluster of CD56dim and CD56 NK cells, and a separate cluster of CD56hiNK cells that share features with both ILCs and CD56dimNK cells. In surprising contrast to mice, tissue repair protein amphiregulin was produced by human NK cells, with higher levels in CD56hiNK cells ...

Towards Community-Driven Metadata Standards For Light Microscopy: Tiered Specifications Extending The Ome Model [Preprint], Mathias Hammer, Maximiliaan Huisman, Farzin Farzam, David Grünwald, Caterina Strambio-De-Castilla

University of Massachusetts Medical School Faculty Publications

Digital light microscopy provides powerful tools for quantitatively probing the real-time dynamics of subcellular structures. While the power of modern microscopy techniques is undeniable, rigorous record-keeping and quality control are required to ensure that imaging data may be properly interpreted (quality), reproduced (reproducibility), and used to extract reliable information and scientific knowledge which can be shared for further analysis (value). Keeping notes on microscopy experiments and quality control procedures ought to be straightforward, as the microscope is a machine whose components are defined and the performance measurable. Nevertheless, to this date, no universally adopted community-driven specifications exist that delineate the ...

Biodiversity Monitoring And Volunteer Motivations: A Case Study On The Imagined Communities Of Citizen Scientists In Meinung, Taiwan, Serena May Calcagno

Master's Projects and Capstones

The Asia Pacific’s biodiversity is under threat. One significant step that can improve conservation is gathering data on what species exist in different areas over time, which can provide insight into ecosystem health. This is especially important in biodiversity hotspots, where high levels of endemism and anthropogenic risk overlap. Though it is one of the few places in the Pacific not classified as a biodiversity hotspot, Taiwan has an unusually high saturation in terms of biodiversity data points. Investigating the motives of biodiversity monitoring volunteerism is already a topic of growing scholarly interest, but relatively few studies have focused ...
