Canine testes thin section culture
Testes tissue culture systems would provide a tool to elucidate spermatogenesis mechanisms, with the aim of genetic preservation of mammals, especially endangered species. Our experiment aims to develop a culture system capable of producing viable mammalian sperm cells in vitro.
Dogs were chosen as the model organism because testes are readily available. Canine testes were obtained from a local veterinary clinic. Thin sections were generated using a commercial electric slicer. They then were cleaned using Dulbecco’s Phosphate-Buffered Saline (DPBS) supplemented with antibiotics then cultured in a modified Tissue Culture Medium 199 (TCM-199). Sections were …

Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas
Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas
MSU Graduate Theses
The first line of defense against bodily insults, like pathogen invasion, is the innate immune system. Innate immunity sets in motion countless cascades that result in inflammation. Inflammation simultaneously affects multiple biological processes like metabolism and gene expression. Males and females react differently to inflammation. To understand both molecular and physiological sex differences in inflammation, we examined how inflammation affects gene expression and glucose metabolism. Adenosine deaminase acting on RNA (ADAR1) is upregulated by inflammation and catalyzes RNA editing, a process where nucleotides encoded by the genome are modified. ADAR1 also controls the innate immune reaction by decreasing activity of …
Perception Of Illness And Its Association With Willingness To Adhere To Treatment In Chronic Hepatitis C Patients With New Diagnosis Of Nonalcoholic Fatty Liver Disease, Carmel Kruse
The Eleanor Mann School of Nursing Capstone Projects
Chronic liver disease is becoming the most common cause of mortality, morbidity, and utilization of healthcare services globally. Both nonalcoholic fatty liver disease (NAFLD) and chronic hepatitis C (CHC) are frequent causes of chronic liver disease. Recently, there have been significant findings on the relationship between NAFLD and CHC; patients with CHC have a higher incidence of NAFLD. The introduction of direct-acting antivirals has cured more CHC patients than ever before. Unfortunately, the current interventions for NAFLD requiring behavioral change remain ineffective. Patient’s ability to follow advice depends largely on their health beliefs; therefore, understanding their illness perception is an …
Effectiveness Of Take-Home Naloxone Programs In Athletic Training: An Evidence-To-Practice Review, Michael J. Palm, Amanda N. Flanscha, Zachary K. Winkelmann
Effectiveness Of Take-Home Naloxone Programs In Athletic Training: An Evidence-To-Practice Review, Michael J. Palm, Amanda N. Flanscha, Zachary K. Winkelmann
Clinical Practice in Athletic Training
The number of opioid overdoses (ODs) has risen in recent years and has become more complex due to the co-involvement of both prescription and illicit opioid drug use. Provisional programs for take-home naloxone (a medication designed to rapidly reverse opiate OD symptoms) kits have been distributed to combat this potentially fatal epidemic. Although there is strong evidence to support the efficacy of naloxone in the reversal of opiate OD, there is limited evidence to support the efficacy of take-home naloxone (THN) kits. The purpose of this evidence-to-practice review was to summarize a systematic review on the efficacy of THN programs. …

Community Opioid Overdose Prevention And Naloxone Distribution Programs: An Evidence-To-Practice Review, Madison M. Hauge, Kathryn C. Downs, Zachary K. Winkelmann
Clinical Practice in Athletic Training
According to the Centers for Disease Control and Prevention, 100 people die of drug overdose in the United States every day. This frighteningly high mortality rate has created the need for community-based opioid overdose prevention programs (OOPPs). Currently, there are more than 188 community-run programs operating in the United States. These programs teach individuals how to distribute naloxone and respond properly to a drug overdose situation. This guiding systematic review depicts the current literature available on OOPPs and their effectiveness. The authors performed an article search to discover the most relevant and recent articles, which were graded using a quality …
Non-Invasive Method For Leptin Supplementation In Zebrafish (Danio Rerio), Regan Mcnamara
Non-Invasive Method For Leptin Supplementation In Zebrafish (Danio Rerio), Regan Mcnamara
Williams Honors College, Honors Research Projects
I tested the hypothesis that recombinant leptin protein can be introduced to zebrafish in vivo through non-invasive soaking in a solution containing the protein. One way to study various molecules’ effects in vivo is through intraperitoneal or intracerebroventricular injections during the embryonic or larval stage, which is invasive, difficult to administer, and can have a high mortality rate. 48 hours post fertilization (hpf) zebrafish were soaked in a His-tagged recombinant leptin protein solution at 10 nM and 100 nM concentrations (produced by Genscript). After soaking, zebrafish larvae were washed extensively to remove all recombinant protein on their exterior before homogenization. …

The intercellular communication mediated by extracellular vesicles (EVs) has gained international interest during the last decade. Interfering with the mechanisms regulating this cellular process might find application particularly in oncology where cancer cell-derived EVs play a role in tumour microenvironment transformation. Although several mechanisms were ascribed to explain the internalization of EVs, little is our knowledge about the fate of their cargos, which are crucial to mediate their function. We recently demonstrated a new intracellular pathway in which a fraction of endocytosed EV-associated proteins is transported into the nucleoplasm of the host cell via a subpopulation of late endosomes penetrating …

Best Practices In Patellar Tendinopathy Management: An Evidence To Practice Review, Christopher J. Burcal, Adam B. Rosen, Tony Taylor, Mike Nicola
Clinical Practice in Athletic Training
Patellar tendinopathy (PT) is a degenerative condition that is common in sporting populations due to the loads placed on the tendon during dynamic activity. PT often occurs in overtraining situations; however, it may also occur in conjunction with and/or worsen through poor biomechanics, persistent inflammation, and altered movement patterns. Although sports medicine practitioners have evidence to support the prevalence of this injury, we do not have a strong base of evidence surrounding the contributing factors and pathophysiology that lead the pain and disability reported in patients with PT. The purpose of this evidence to practice review was to summarize a …
Loss Of Marv1 Promotes Chop Signaling In Mouse Liver, Shad Anthony Mitchell
Loss Of Marv1 Promotes Chop Signaling In Mouse Liver, Shad Anthony Mitchell
Graduate School of Biomedical Sciences Theses and Dissertations
Metabolic syndrome (MetS) is a term used to define a set of metabolic diseases: obesity, type 2 diabetes (T2D), hyperlipidemia, hypertension, nonalcoholic fatty liver disease (NAFLD), and nonalcoholic hepatosteatosis (NASH). Those with MetS have a higher incidence of cardiovascular disease and stroke. Current drug treatments for MetS treat the individual pathologies associated with the diseases, rather than directly targeting MetS as a whole. We hypothesize that the inhibition of a ubiquitous lipid transporter known as ARV1 can improve pathologies associated with MetS. To test this hypothesis, we utilized liver tissue from mARV1 knockout mice fed a high-fat diet and examined …
Regulation Of The Tubulin Homolog Ftsz In Escherichia Coli, Monika S. Buczek
Regulation Of The Tubulin Homolog Ftsz In Escherichia Coli, Monika S. Buczek
Dissertations, Theses, and Capstone Projects
Escherichia coli is a well-known pathogen, and importantly, a widely used model organism in all fields of biological sciences for cloning, protein purification, and as a model for Gram-negative bacterial species. And yet, researchers do not fully understand how this bacterium replicates and divides. Every year additional division proteins are discovered, which adds complexity to how we understand E. coli undergoes cell division. Due to their specific roles in cytokinesis, some of these proteins may be potential targets for development of antibacterials or bacteriostatics, which are much needed for fighting the current global antibacterial deficit. My thesis work focuses on …
The Effect Of Diet On Midgut And Resulting Changes In Infectiousness Of Acmnpv Baculovirus In Trichoplusia Ni, Elizabeth Chen
The Effect Of Diet On Midgut And Resulting Changes In Infectiousness Of Acmnpv Baculovirus In Trichoplusia Ni, Elizabeth Chen
Electronic Thesis and Dissertation Repository
The cabbage looper, Trichoplusia ni, a global generalist lepidopteran pest, has developed resistance to many synthetic and biological insecticides, requiring effective and environmentally acceptable alternatives. One possibility is the Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV). This baculovirus is highly infectious for T. ni, with potential as a biocontrol agent, however, its effectiveness is strongly influenced by dietary context. In this study, microscopy and transcriptomics were used to examine how the efficacy of this virus was affected when T. ni larvae were raised on different diets. Larvae raised on potato host plants had lower chitinase and chitin deacetylase transcript levels …
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Williams Honors College, Honors Research Projects
Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.
Objectives: To evaluate the use of biomarkers in children seen in the Emergency …

The Thioredoxin Trx-1 Regulates The Major Oxidative Stress Response Transcription Factor, Skn-1, In Caenorhabditis Elegans, Katie C. Mccallum
Dissertations & Theses (Open Access)
The ability to respond to hostile environmental conditions is critical for the survival of an organism. Oxidative stress is an adverse state in which reactive oxygen species (ROS) accumulate to a harmful level and, if left unresolved, can lead to cellular dysfunction and organismal disease. Sophisticated detoxification systems, characterized by a battery of enzymatic antioxidants, are utilized to neutralize ROS thereby reducing stress. However, ROS are also purposefully produced by designated cellular enzymes to facilitate the signaling and regulation of critical physiological processes. Therefore, both the production and neutralization of ROS must be tightly controlled. Indeed, the expression of detoxification …

Steroid hormones organize many aspects of development, including that of the nervous system. Steroids also play neuromodulatory and other activational roles, including regulation of sensitivity to painful stimuli in mammals. In Drosophila, ecdysteroids are the only steroid hormones, and therefore the fly represents a simplified model system in which to explore mechanisms of steroid neuromodulation of nociception. In this report, we present evidence that ecdysteroids, acting through two isoforms of their nuclear ecdysone receptor (EcR), modulate sensitivity to noxious thermal and mechanical stimuli in the fly larva. We show that EcRA and EcRB1 are expressed by third instar larvae in …

The Effects Of Ocean Acidification And Eutrophication On The Growth, Lipid Composition And Toxicity Of The Marine Raphidophyte Heterosigma Akashiwo., Julia Rose Matheson
Electronic Thesis and Dissertation Repository
Anthropogenic forcing, such as ocean acidification caused by rising carbon dioxide emissions, and eutrophication due to increased nutrient loadings in run-off, are causing major changes to the biogeochemistry of the oceans. As a consequence, coastal phytoplankton are susceptible to altered biogeochemical environments. This study examined the effect of a lower pH and increased levels of nutrients on the common coastal harmful alga, Heterosigma akashiwo. Growth rates, maximal cell yields, neutral lipid accumulation and toxicity of cells grown under various pH and nutrients regimes were measured. H. akashiwo growth was near maximal when grown at lower pH levels. There was …
Systematics Of Protosteloid Amoebae, Lora Lindley Shadwick
Systematics Of Protosteloid Amoebae, Lora Lindley Shadwick
Graduate Theses and Dissertations
Because of their simple fruiting bodies consisting of one to a few spores atop a finely tapering stalk, protosteloid amoebae, previously called protostelids, were thought of as primitive members of the Eumycetozoa sensu Olive 1975. The studies presented here have precipitated a change in the way protosteloid amoebae are perceived in two ways: (1) by expanding their known habitat range and (2) by forcing us to think of them as amoebae that occasionally form fruiting bodies rather than as primitive fungus-like organisms. Prior to this work protosteloid amoebae were thought of as terrestrial organisms. Collection of substrates from aquatic habitats …

Salmonids, such as Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss), are a staple economic, recreational, tribal, and environmental resource, yet many populations are unsustainable. This study was part of a broad scale effort to monitor the impact of downstream migration obstacles on juvenile salmonid health and survival, which is an essential step towards increasing Smolt-to-Adult Return ratios (SARs). The objective of this study was to determine if juvenile Chinook salmon and steelhead exhibit differing quantities of alphaII-Spectrin Breakdown Products (SBDPs) over two consecutive spring migration periods, indicative of neurogenesis rate and/or biological response to head …
