Intestinal Stem Cells To Advance Drug Development, Precision, And Regenerative Medicine: A Paradigm Shift In Translational Research, Jonathan P. Mochel, Albert E. Jergens, Dawn Kingsbury, Hyun Jung Kim, Martín G. Martín, Karin Allenspach 2018 Iowa State University

Intestinal Stem Cells To Advance Drug Development, Precision, And Regenerative Medicine: A Paradigm Shift In Translational Research, Jonathan P. Mochel, Albert E. Jergens, Dawn Kingsbury, Hyun Jung Kim, Martín G. Martín, Karin Allenspach

Biomedical Sciences Publications

Recent advances in our understanding of the intestinal stem cell niche and the role of key signaling pathways on cell growth and maintenance have allowed the development of fully differentiated epithelial cells in 3D organoids. Stem cell-derived organoids carry significant levels of proteins that are natively expressed in the gut and have important roles in drug transport and metabolism. They are, therefore, particularly relevant to study the gastrointestinal (GI) absorption of oral medications. In addition, organoids have the potential to serve as a robust preclinical model for demonstrating the effectiveness of new drugs more rapidly, with more certainty, and at ...


Concurrent Renal Amyloidosis And Thymoma Resulting In A Fatal Ventricular Thrombus In A Dog, Jennifer M. Loewen, Rachel E. Cianciolo, Liwen Zhang, Michael Yaeger, Jessica L. Ward, Jodi D. Smith, Dana N. LeVine 2018 Iowa State University

Concurrent Renal Amyloidosis And Thymoma Resulting In A Fatal Ventricular Thrombus In A Dog, Jennifer M. Loewen, Rachel E. Cianciolo, Liwen Zhang, Michael Yaeger, Jessica L. Ward, Jodi D. Smith, Dana N. Levine

Veterinary Clinical Sciences Publications

Thymoma‐associated nephropathies have been reported in people but not in dogs. In this report, we describe a dog with thymoma and concurrent renal amyloidosis. A 7‐year‐old castrated male Weimaraner was presented for progressive anorexia, lethargy, and tachypnea. The dog was diagnosed with azotemia, marked proteinuria, and a thymoma that was surgically removed. Postoperatively, the dog developed a large left ventricular thrombus and was euthanized. Necropsy confirmed the presence of a left ventricular thrombus and histopathology revealed renal amyloidosis. We speculate that the renal amyloidosis occurred secondary to the thymoma, with amyloidosis in turn leading to nephrotic syndrome ...

This poster presentation will discuss the pros and cons of spaying or neutering household pets. Many animals are euthanized annually due to overpopulation issues, so pet owners have been urged to neuter/spay their household pets to limit overpopulation. Recent research suggests that early neutering may have negative consequences for companion animals. The goal of the presentation is to educate the public about the benefits and risks associated with pet reproductive procedures.

Veterinary Diagnostic and Production Animal Medicine Publications

Background

A method of quantifying clinical bleeding in dogs with immune thrombocytopenia (ITP) is needed because ITP patients have variable bleeding tendencies that inconsistently correlate with platelet count. A scoring system will facilitate patient comparisons and allow stratification based on bleeding severity in clinical trials.

Hypothesis/Objectives

To develop and evaluate a bleeding assessment tool for dogs, and a training course for improving its consistent implementation.

Animals

Client‐owned dogs (n = 61) with platelet counts <50,000/μL; 34 classified as primary ITP, 17 as secondary ITP, and 10 as non‐ITP.

Methods

A novel bleeding assessment tool, DOGiBAT, comprising bleeding grades from 0 (none) to 2 (severe) at 9 anatomic sites, was developed. Clinicians and technicians ...


Grace Peterson Research Colloquium, Emma Pfeiffer 2017 DePaul University

Grace Peterson Research Colloquium, Emma Pfeiffer

Grace Peterson Nursing Research Colloquium

Mental illness is commonly under-diagnosed, misdiagnosed, or untreated, particularly in the elderly population. An expected population increase for those 65 years and older, increased in health care expenses coupled with the moral and ethical obligation of health care providers to promote quality of life at all ages makes investigation to alternative treatments in this population is worth investigating. The purpose of this literature review is to synthesize existing studies to clarify the following questions: What are the effects of pet therapy on those experiencing signs and symptoms of depression and anxiety? Why is pet therapy still lagging in validated studies ...


Spotlight On The Perioperative Use Of Maropitant Citrate, Bonnie L. Hay Kraus 2017 Iowa State University

Spotlight On The Perioperative Use Of Maropitant Citrate, Bonnie L. Hay Kraus

Veterinary Clinical Sciences Publications

Neurokinin-1 (NK-1) receptors are present in both the central nervous system and peripheral tissues. Substance P (SP) is the major ligand and is involved in multiple processes including pain transmission, vasodilation, modulation of the inflammatory response, as well as the sensory neuronal transmission involved in stress, anxiety, and emesis. The involvement of NK-1 and SP in the vomiting reflex has led to the development of NK-1 antagonists to prevent and treat vomiting in human and veterinary medicine. Maropitant is a potent, selective neurokinin (NK-1) receptor antagonist that blocks the pharmacologic action of SP in the central nervous system. Maropitant is ...


The Effects Of Reward-Based Training On The Behavioral Assessment Of The Domestic Dog, Shelby Vandergraff, Shelby K. Vandergraff 2017 Murray State University

The Effects Of Reward-Based Training On The Behavioral Assessment Of The Domestic Dog, Shelby Vandergraff, Shelby K. Vandergraff

Murray State Theses and Dissertations

Contrary to popular belief, pet overpopulation is caused more by owners failing to keep their dog than with accidental or intentional breeding (Moulton et al., 1991). Factors related to relinquishment have been researched, and concluded that behavioral problems are the most reoccurring reasons observed (Bailey, 1992; Miller at al., 1996; Patronek et al., 1996; Serpell, 1966; Salman et al., 1998, 2000; Scarlett et al, 1999; New et al., 2000; Shore et al., 2003, 2005; Mondelli 2004, Blackwell et al., 2008). When animals are relinquished to the shelter, the likelihood of the animal being euthanized increases. The purpose of this research ...

Animal Science Publications

State-of-the-art health care includes genome sequencing of the patient to identify genetic variants that contribute to either the cause of their malady or variants that can be targeted to improve treatment. The goal was to introduce state-of-the-art health care to cats using genomics and a precision medicine approach. To test the feasibility of a precision medicine approach in domestic cats, a single cat that presented to the University of Missouri, Veterinary Health Center with an undiagnosed neurologic disease was whole-genome sequenced. The DNA variants from the cat were compared to the DNA variant database produced by the 99 Lives Cat ...

African black-footed cats (Felis nigripes) are endangered wild felids. One male and full-sibling female African black-footed cat developed vision deficits and mydriasis as early as 3 months of age. The diagnosis of early-onset progressive retinal atrophy (PRA) was supported by reduced direct and consensual pupillary light reflexes, phenotypic presence of retinal degeneration, and a non-recordable electroretinogram with negligible amplitudes in both eyes. Whole genome sequencing, conducted on two unaffected parents and one affected offspring was compared to a variant database from 51 domestic cats and a Pallas cat, revealed 50 candidate variants that segregated concordantly with the PRA phenotype. Testing ...

A 10-year-old Labrador Retriever who had been undergoing therapy for a recurrent hemangiopericytoma of the right flank presented to the Kansas State University Ophthalmology service for evaluation of a painful left eye. Examination revealed secondary glaucoma and irreversible blindness of the affected eye and multifocal chorioretinal lesions in the fellow eye. Therapeutic and diagnostic enucleation of the left eye was performed and histopathologic examination demonstrated the presence of a presumed metastatic spindle cell sarcoma. Further immunohistochemical staining confirmed the intraocular neoplasia to be metastatic spread from the previously removed flank mass. Rapid progression in size and number of chorioretinal lesions ...


Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala 2017 University of Helsinki

Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala

Animal Sentience

It is not possible to demonstrate that dogs (Canis familiaris) feel emotions, but the same is true for all other species, including our own. The issue must therefore be approached indirectly, using premises similar to those used with humans. Recent methodological advances in canine research reveal what dogs experience and what they derive from the emotions perceptible in others. Dogs attend to social cues, they respond appropriately to the valence of human and dog facial expressions and vocalizations of emotion, and their limbic reward regions respond to the odor of their caretakers. They behave differently according to the emotional situation ...

Veterinary Diagnostic and Production Animal Medicine Publications

The intestinal microbiota is increasingly linked to the pathogenesis of idiopathic inflammatory bowel disease (IBD) in dogs. While studies have reported alterations in fecal (luminal) microbial populations, only limited information is available about the mucosal microbiota of IBD dogs at diagnosis and following medical therapy. Our aim was to characterize the mucosal microbiota and determine the clinical, microbiological, and mucosal homeostatic effects of probiotic treatment in dogs with IBD. Thirty four IBD dogs were randomized to receive standard therapy (ST = diet + prednisone) with or without probiotic. Tissue sections from endoscopic biopsies were evaluated by fluorescence in situ hybridization (FISH) on ...


Identification Of Feline Tritrichomonas Foetus Surface Epitopes: Putative Targets For Development Of A Novel Diagnostic Test For Feline Trichomonosis, Emily Nissa Gould 2016 University of Tennessee - Knoxville

Identification Of Feline Tritrichomonas Foetus Surface Epitopes: Putative Targets For Development Of A Novel Diagnostic Test For Feline Trichomonosis, Emily Nissa Gould

Masters Theses

BACKGROUND: Tritrichomonas foetus (T. foetus) is a flagellated protozoa that infects the distal ileum and proximal colon of domestic cats and also induces reproductive failure in cattle. Although feline trichomonosis is recognized to have a global prevalence of up to 30%, it still poses a diagnostic and therapeutic challenge to veterinarians; thus, there is a need for both improved diagnostics and therapeutics. Despite differing organ tropism between genotypes, evidence exists for conserved virulence factors between feline and bovine T. foetus. Two epitopes (1.15 and 1.17) of the bovine T. foetus glycosylated surface antigen 1.15-1.17 have been ...

Introduction: Chemotherapy-induced nausea and vomiting (CINV) is a common side effect of chemotherapeutic treatment experienced by dogs that can lower quality of life and functionality. These symptoms are likewise found in people receiving chemotherapy; however, human oncology has well-established protocols for preventing these side effects, while veterinary medicine does not. The objective of this research is to establish a baseline regarding current standard of care to determine how veterinary specialists are managing CINV in dogs receiving chemotherapy.

Animal-Assisted Therapy For Military Veterans With Posttraumatic Stress Disorder: An Investigation On The Positive Effects Of Attachment And Affiliation Behaviors, Sara Miele 2016 Dominican University of California

Animal-Assisted Therapy For Military Veterans With Posttraumatic Stress Disorder: An Investigation On The Positive Effects Of Attachment And Affiliation Behaviors, Sara Miele

Scholarly & Creative Works Conference 2018

Posttraumatic stress disorder (PTSD) develops in people who have experienced a traumatic event (nimh.nih.gov, 2016). Because PTSD is a chronic disorder, it is associated with impaired quality of life (Stern et al., 2013). A specific population at high risk for developing PTSD is military veterans. It is estimated over half a million military veterans suffer from PTSD (Stern et al., 2013). Although there are psychological services and treatments for veterans, many do not seek help because fear of the negative stigma associated with mental illness (Lanning & Krenek, 2013). Recently, efforts have been made to implement veteran friendly treatment ...

Pharmacy Faculty Articles and Research

Objective—To investigate molecular mechanisms mediating anti-fibrotic effect of SAHA in the canine cornea using an in vitro model. We hypothesized that SAHA attenuates corneal fibrosis by modulating Smad-dependent and, to a lesser extent, Smad-independent signaling pathways activated by TGF-β1, as well as matrix metalloproteinase (MMP) activity.

Methods—Cultured canine corneal fibroblasts (CCF) were incubated in the presence/absence of TGF-β1 (5ng/ml) and SAHA (2.5μM) for 24hrs. Western blot analysis was used to quantify non-phosphorylated and phosphorylated isoforms of Smad2/3, p38 MAP kinase (MAPK), ERK1/2 and JNK1. Real-time PCR and zymography were utilized to quantify MMP1 ...

Pharmacy Faculty Articles and Research

The aim of this study was to develop a novel in vivo corneal model of fibrosis in dogs utilizing alkali burn and determine the ability of suberanilohydroxamic acid (SAHA) to inhibit corneal fibrosis using this large animal model. To accomplish this, we used seven research Beagle dogs. An axial corneal alkali burn in dogs was created using 1 N NaOH topically. Six dogs were randomly and equally assigned into 2 groups: A) vehicle (DMSO, 2 μL/mL); B) anti-fibrotic treatment (50 μM SAHA). The degree of corneal opacity, ocular health, and anti-fibrotic effects of SAHA were determined utilizing the Fantes ...


Anesthesia For Cesarean Section In The Dog, Bonnie Hay Kraus 2016 Iowa State University

Anesthesia For Cesarean Section In The Dog, Bonnie Hay Kraus

Veterinary Clinical Sciences Publications

The major goal in anesthesia for cesarean section (CS) is to minimize fetal effects of anesthetic drugs in order to minimize fetal respiratory, central nervous system and cardiovascular depression and deliver live, vigorous puppies. Of equal importance is to provide adequate analgesia to the dam and prevent anesthesia-related complications such as hypotension, hypoventilation, hypoxemia, hemorrhage and hypothermia, which will increase morbidity and mortality in both mother and puppies. The physiochemical properties which allow drugs to cross the blood-brain barrier also facilitate crossing of the placenta, therefore the assumption should be made (with very few exceptions) that anes- thetics, analgesics and ...
