Breeding Season Ecology And Demography Of Lesser Scaup (Aythya Affinis) At Red Rock Lakes National Wildlife Refuge, Jeffrey M. Warren 2018 Utah State University

Breeding Season Ecology And Demography Of Lesser Scaup (Aythya Affinis) At Red Rock Lakes National Wildlife Refuge, Jeffrey M. Warren

All Graduate Theses and Dissertations

It is hypothesized that individuals make reproductive decisions based on current assessments of their physiological condition and environmental conditions. For female lesser scaup (Aythya affinis), breeding occurs after an energetically costly spring migration. Increasing fat reserves (i.e., ‘body condition’) prior to breeding allows a female to produce a larger clutch of eggs, but time spent gaining body condition is costly in terms of time allowed to raise ducklings before freezing conditions in the fall. In Chapter 2 I explored rate of pre-breeding body condition gain in female lesser scaup, and how that rate influenced clutch size. Spring phenology, measured ...

Mouse Aorta-Derived Mesenchymal Progenitor Cells Contribute To And Enhance The Immune Response Of Macrophage Cells Under Inflammatory Conditions, Jodi F. Evans Ph.D., Veronica Salvador, Sheela George, Cristina Trevino-Gutierrez, Catherine Nunez 2018 Molloy College

Mouse Aorta-Derived Mesenchymal Progenitor Cells Contribute To And Enhance The Immune Response Of Macrophage Cells Under Inflammatory Conditions, Jodi F. Evans Ph.D., Veronica Salvador, Sheela George, Cristina Trevino-Gutierrez, Catherine Nunez

Jodi Evans

Abstract Introduction: Mesenchymal progenitor cells interact with immune cells and modulate inflammatory responses. The cellular characteristics required for this modulation are under fervent investigation. Upon interaction with macrophage cells, they can contribute to or suppress an inflammatory response. Current studies have focused on mesenchymal progenitors derived from bone marrow, adipose, and placenta. However, the arterial wall contains many mesenchymal progenitor cells, which during vascular disease progression have the potential to interact with macrophage cells. To examine the consequence of vascular-tissue progenitor cell-macrophage cell interactions in an inflammatory environment, we used a recently established mesenchymal progenitor cell line derived from the ...


Mouse Mesenchymal Progenitor Cells Expressing Adipogenic And Osteogenic Transcription Factors Suppress The Macrophage Inflammatory Response, Jodi F. Evans Ph.D., Natalie Fernandez, Heather Renna, Lauren McHugh, Katie Mazolkova, William Crugnola 2018 Molloy College

Mouse Mesenchymal Progenitor Cells Expressing Adipogenic And Osteogenic Transcription Factors Suppress The Macrophage Inflammatory Response, Jodi F. Evans Ph.D., Natalie Fernandez, Heather Renna, Lauren Mchugh, Katie Mazolkova, William Crugnola

Jodi Evans

Mesenchymal progenitor cell characteristics that can identify progenitor populations with specific functions in immunity are actively being investigated. Progenitors from bone marrow and adipose tissue regulate the macrophage (MΦ) inflammatory response by promoting the switch froman inflammatory to an anti-inflammatory phenotype.Conversely,mesenchymal progenitors fromthe mouse aorta (mAo) support and contribute to the MΦ response under inflammatory conditions.We used cell lines with purported opposing immune-regulatory function, a bonemarrow derivedmesenchymal progenitor cell line (D1) and amouse aorta derived mesenchymal progenitor cell line (mAo). Their interaction and regulation of the MΦ cell response to the inflammatory mediator, lipopolysaccharide (LPS), was examined ...


High Glucose Enhances The Proliferation Effects Of Stress Hormones In Mesenchymal Stem Cell Cultures, Jodi F. Evans Ph.D., Nancy Abrego, Louis Ragolia 2018 Molloy College

High Glucose Enhances The Proliferation Effects Of Stress Hormones In Mesenchymal Stem Cell Cultures, Jodi F. Evans Ph.D., Nancy Abrego, Louis Ragolia

Jodi Evans

Mesenchymal stem cells (MSC) are the progenitor cells to connective tissue cells, epithelial cells, and smooth muscle cells. These cells are currently being investigated as a cellular source for tissue regeneration and repair. The systemic and local tissue environment may have significant influence on the success of such efforts. We hypothesized that elevated glucose and exposure to stress hormones would influence the proliferation of MSC. MSC from the bone marrow of Wistar-Kyoto (WKY) rats were grown under both low glucose (5 mM) and high glucose (20 nM) conditions in the presence and absence of the synthetic glucocorticoid, dexamethasone, and adrenocorticotropin ...

Vascular Tissue-Resident Mesenchymal Stem Cells; Friend Or Foe?, Jodi F. Evans Ph.D., Heather Renna, Lauren Mchugh, Eddie Bochynski, Victoria Flemm

Jodi Evans

Mesenchymal stem cells (MSC) are ideal candidates for stem cell-based therapies of vascular inflammation. They are progenitor cells that can replace damaged cells and they can modulate immune response cells. MSC from bone marrow and adipose tissue regulate inflammation by promoting the switch of macrophage cell from an inflammatory to an anti-inflammatory phenotype. Much less is known about the tissue resident MSC’s and their interaction with macrophage cells. We hypothesized that aortaderived mesenchymal stem cells (mAo MSC) would also promote the expression of the antiinflammatory phenotype among macrophage cells. The interaction of mAo MSC with the macrophage was examined ...


The Stress Of Public Speaking Increases Cortisol Levels In Undergraduates: Is Increased Preparation Really The Best Remedy?, Jodi F. Evans Ph.D., Erin Clinton, Grace Cookson, Stephanie Brown, Daniel Woods 2018 Molloy College

The Stress Of Public Speaking Increases Cortisol Levels In Undergraduates: Is Increased Preparation Really The Best Remedy?, Jodi F. Evans Ph.D., Erin Clinton, Grace Cookson, Stephanie Brown, Daniel Woods

Jodi Evans

Perceived stress is prevalent among the undergraduate population. When this stress persists, it has the potential to lead to mental health illnesses. Recent research shows 85% of students experience overwhelming anxiety from academic pressures. Physiologically, during stressful events, cortisol levels rise in the body which disrupts homeostasis. The anticipation prior to a class presentation, a form of public speaking, is a common source of perceived stress among undergraduates. The focus of this experiment was to determine if there is a correlation between factors such as increased preparedness, sleep, level of understanding, perceived anxiety and physiological stress parameters. Twenty-eight student volunteers ...


Stress Axis Hormones Induce Triglyceride Filled Nodule Formation In Vascular Smooth Muscle Cells, Jodi F. Evans Ph.D., Michelle Vigliotti, Pamela Tello 2018 Molloy College

Stress Axis Hormones Induce Triglyceride Filled Nodule Formation In Vascular Smooth Muscle Cells, Jodi F. Evans Ph.D., Michelle Vigliotti, Pamela Tello

Jodi Evans

Homeostatic stress, such as that which occurs in diabetes, is associated with increased risk for the development of atherosclerosis. Atherosclerotic plaques of the artery wall are associated with both lipid accumulation and fibrous and/or calcified tissue accumulation. Vascular smooth muscle cells (VSMC) are derived from mesenchymal stem cells (MSC) which are capable of differentiating into adipocytes, chondrocytes and osteoblasts. MSC of the bone marrow are pushed toward the chondrogenic and adipogenic phenotypes in the presence of the stress hormones glucocorticoid and adrenocorticotropin (ACTH). This led us to hypothesize that the proliferative VSMC of the Goto-Kakizaki (GK) diabetic rat, when ...


Effect Of Circular Motion Exercise On Bone Modeling And Bone Mass In Young Rats: An Animal Model Of Isometric Exercise, Jodi F. Evans Ph.D., J. K. Yeh, Q. Niu, J. Iwamoto, J. F. Aloia 2018 Molloy College

Effect Of Circular Motion Exercise On Bone Modeling And Bone Mass In Young Rats: An Animal Model Of Isometric Exercise, Jodi F. Evans Ph.D., J. K. Yeh, Q. Niu, J. Iwamoto, J. F. Aloia

Jodi Evans

The aims of the study are to develop a non-invasive animal model of circular motion exercise and to evaluate the effect of this type of exercise on bone turnover in young rats. The circular motion exercise simulates isometric exercise using an orbital shaker that oscillates at a frequency of 50 Hz and is capable of speeds from 0-400 rpm. A cage is fixed on top of the shaker and the animals are placed inside. When the shaker is turned on, the oscillatory movement should encourage the animals to hold on to the cage and use various muscle forces to stabilize ...


Acth Enhances Lipid Accumulation In Bone-Marrow Derived Mesenchymal Stem Cells Undergoing Adipogenesis, Jodi F. Evans Ph.D., Thomas Rhodes, Michelle Pazienza 2018 Molloy College

Acth Enhances Lipid Accumulation In Bone-Marrow Derived Mesenchymal Stem Cells Undergoing Adipogenesis, Jodi F. Evans Ph.D., Thomas Rhodes, Michelle Pazienza

Jodi Evans

ACTH is a major hormone of the stress axis or hypothalamic-pituitary-adrenal (HPA) axis. It is derived from pro-opiomelanocortin (POMC) the precursor to the melanocortin family of peptides. POMC produces the biologically active melanocortin peptides via a series of enzymatic steps in a tissue-specific manner, yielding the melanocyte-stimulating hormones (MSHs), corticotrophin (ACTH) and β-endorphin. The melanocortin system plays an imperative role in energy expenditure, insulin release and insulin sensitivity. Bone marrow derived mesenchymal stem cells circulate in the blood stream and as progenitor cells have the potential to differentiate into many cell types such as osteoblasts, chondrocytes and adipocytes. Here we ...


Adrenocorticotropin Hormone Expression In The Developing Chicken Limb, Jodi F. Evans Ph.D., Michelle Vigliotti 2018 Molloy College

Adrenocorticotropin Hormone Expression In The Developing Chicken Limb, Jodi F. Evans Ph.D., Michelle Vigliotti

Jodi Evans

In previous studies using mammalian models we have found both clinical and laboratory evidence of a role for melanocortins in endochondral ossification. The melanocortin system has remarkable conservation among vertebrates and melanocortin receptors are expressed with significant sequence homology in teleosts to mammals. The overall goal of these studies is to provide a more accessible model of melanocortin involvement in endochondral growth. We hope to determine if melanocortins play a role during endochondral ossification of the developing chicken limb. Like in mammals melanocortins are widely distributed throughout the body of chicken and participate in a wide range of physiological functions ...

Cd105 Deficieny In Mouse Aorta-Derived Mesenchymal Stem Cells Promotes An Enhanced Inflammatory Response To Lipolysaccharide., Jodi F. Evans Ph.D., Joseph Granata, Hugo Sanchez, Philip Loeschinger, Anthony Goez

Jodi Evans

Mesenchymal stem cells (MSCs) are being widely studied for their ability to regulate macrophage cell responses. Previous works have demonstrated that mouse aorta-derived MSC (mAo-MSC) support the macrophage inflammatory response. mAo-MSC have been characterized phenotypically for MSC-associated surface antigens and express CD90 and CD105 but do not express CD73. CD105, also known as endoglin, is a coreceptor in the TGFβ superfamily of receptors. Mouse adipose-derived MSC lacking CD105 have an increased capacity to regulate T-cells by reducing their proliferation while elevated CD105 expression is consistently associated with inflammatory disease. Therefore, we hypothesized that suppression of CD105 in mAo-MSC will reduce ...

A Quest For A Custom-Made Mesenchymal Stem Cell In The Treatment Of Inflammatory Diseases, Jodi F. Evans Ph.D., Natalie Fernandez, Caroline Winters, Maria Barandica, Abi Ocava, Michael Delsignore, Kristina Coppola

Jodi Evans

Mesenchymal stem cells (MSC) are multipotent cells that can differentiate into adipocytes, osteoblasts and chondrocytes. These cells are widely studied in tissue regeneration and for their therapeutic effects in inflammatory disease. MSC interact with cells of the innate and adaptive immunity to promote or suppress the inflammatory response. MSC from the bone marrow (D1 MSC) decrease inflammatory responses by lowering macrophage (Mᶲ) secretion of soluble factors such as nitric oxide (NO), interleukin-12 (IL-12) and tumor necrosis factor-α (TNFα). Aorta-derived MSC (mAo MSC) support the macrophage inflammatory response by contributing to NO secretion and enhancing secretion of TNFα by Mᶲ. Previous ...


When Extinction Is More Ethical Than Conservation: The Endangered Species Act And The Keystone Dilemma, Miranda F. Thomas 2018 Danville Community College

When Extinction Is More Ethical Than Conservation: The Endangered Species Act And The Keystone Dilemma, Miranda F. Thomas

Exigence

This paper examines how the Endangered Species Act's measures to protect endangered species have resulted in increased rates of extinction. The author summarizes the concept of endangered keystone species and explains the processes and operations of the environmental legislation enacted to protect the species. The paper discusses the harmful consequences that certain laws have had on both species and humans, such as misappropriating resources to species that are not as endangered as others, and abusing regulations in manners that punish people for conservation efforts. By examining opposing arguments that favor increased regulation, this paper explains through data from leading ...

Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D. 2018 Molloy College

Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D.

Dr. John T. Tanacredi

A periodic pause to intensely observe a singularly unique ecosystem sharpens one's awareness of this diverse world of ours, especially, as the author notes, if one observes a transitional ecosystem whose ecological treasures are hidden or maybe obscured by a tidal sediment's resemblance to a large, rotten cheese! "It smells, is slimy and sticky, is punched with holes and crowded with various worms." Sounds good to me! Reise's "pause" encompasses 10 years in which he investigated the Wadden Sea mudflats near the border between West Germany and Denmark. He uses this site to discuss the biotic and ...


Variability In Growth And Age Structure Among Populations Of Ribbed Mussels, Geukensia Demissa (Dillwyn) (Bivalvia: Mytilidae), In Jamacia Bay, New York (Gateway Nra), John Tanacredi Ph.D., David R. Franz 2018 Molloy College

Variability In Growth And Age Structure Among Populations Of Ribbed Mussels, Geukensia Demissa (Dillwyn) (Bivalvia: Mytilidae), In Jamacia Bay, New York (Gateway Nra), John Tanacredi Ph.D., David R. Franz

Dr. John T. Tanacredi

Growth rates, body weight, density and biomass of ribbed mussels, Geukensia demissa (Dillwyn), were determined at Spartina alterniflora marsh-flat sites in Jamaica Bay, New York (Lower Hudson Estuary). Cumulative growth and annual growth increments varied but rates were lower at sites within the central bay relative to peripheral sites. Local variability both in size at Ring-1 and size-specific annual growth rates probably account for the variability in cumulative length. No pattersn were noted in frequency distributions of shell size but congruence in age structure was observed among neighboring sites in some areas of the bay. Mussel densities were greater within ...
