Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes 2018 University of Maine

Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes

Electronic Theses and Dissertations

Bacterial uterine infections inflict major losses on the equine breeding industry. These infections usually arise from bacteria introduced at breeding. Micro-currents propelled by ciliated cells between the folds of the uterus and cervix have been proposed as a means by which contaminants are expelled. Previous data have shown possible ciliary micro-currents propelling carbon particles, occasionally rotating, through cervical folds. However, adherence to the epithelium may have interfered with movement of carbon in these studies. Therefore, we tested potentially non-adherent substances to reveal ciliary micro-currents on the equine cervix under high magnification video-endoscopy. We hypothesized that polyethylene green microspheres 1 - 5 ...


Human Induced Rotation And Reorganization Of The Brain Of Domestic Dogs, Taryn Roberts, Paul McGreevy, Michael Valenzuela 2018 University of Sydney

Human Induced Rotation And Reorganization Of The Brain Of Domestic Dogs, Taryn Roberts, Paul Mcgreevy, Michael Valenzuela

Paul McGreevy, Ph.D.

Domestic dogs exhibit an extraordinary degree of morphological diversity. Such breed-to-breed variability applies equally to the canine skull, however little is known about whether this translates to systematic differences in cerebral organization. By looking at the paramedian sagittal magnetic resonance image slice of canine brains across a range of animals with different skull shapes (N = 13), we found that the relative reduction in skull length compared to width (measured by Cephalic Index) was significantly correlated to a progressive ventral pitching of the primary longitudinal brain axis (r = 0.83), as well as with a ventral shift in the position of ...


Long-Term Outcome And Complications Of 32 Distal Femoral Osteotomies Performed For Correction Of Mpl In Dogs Without Cranial Cruciate Disease, Nicholas Crawfis 2018 The University of Akron

Long-Term Outcome And Complications Of 32 Distal Femoral Osteotomies Performed For Correction Of Mpl In Dogs Without Cranial Cruciate Disease, Nicholas Crawfis

Honors Research Projects

Many canines suffer severe, grade I-IV, medial patella luxation causing a persistent lameness, severely reducing the quality of life for the dog (Linney et al 2011). For these patients surgical intervention is recommended to alleviate these symptoms. The procedure used to do so is a distal femoral osteotomy (DFO). This procedure allows for correction of torsion in the femur and quadriceps mechanism, and frontal plane abnormalities at the same time. The present study aims to describe the long-term outcome and related complications of 32 DFOs, without concomitant Cranial Cruciate Ligament rupture (CCLR), in a large private practice referral hospital based ...

Developing Learning Models To Teach Equine Anatomy And Biomechanics, Zandalee E. Toothaker 2017 University of Maine

Developing Learning Models To Teach Equine Anatomy And Biomechanics, Zandalee E. Toothaker

Honors College

Animal owners and professionals benefit from an understanding of an animal’s anatomy and biomechanics. This is especially true of the horse. A better understanding of the horse’s anatomy and weight bearing capabilities will allow people to treat and prevent injuries in equine athletes and work horses. Currently, teaching anatomy is based on dissection of cadavers and study of figures in textbooks. Dissection is expensive and presents logistical difficulties associated with sourcing, storage, and disposal of cadavers. Also, post mortem tissue changes obscure how the muscles support the bones and make the specimens unsuitable for representing biomechanical principles. Cadavers ...

The reporting of observational studies in veterinary research presents many challenges that often are not adequately addressed in published reporting guidelines. A consensus meeting of experts was organized to develop an extension of the STROBE statement to address observational studies in veterinary medicine with respect to animal health, animal production, animal welfare and food safety outcomes. The consensus meeting was held 11–13 May 2014 in Mississauga, Ontario, Canada. Seventeen experts from North America, Europe and Australia attended the meeting. The experts were epidemiologists and biostatisticians, many of whom hold or have held editorial positions with relevant journals. Prior to ...

The STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement was first published in 2007 and again in 2014. The purpose of the original STROBE was to provide guidance for authors, reviewers and editors to improve the comprehensiveness of reporting; however, STROBE has a unique focus on observational studies. Although much of the guidance provided by the original STROBE document is directly applicable, it was deemed useful to map those statements to veterinary concepts, provide veterinary examples and highlight unique aspects of reporting in veterinary observational studies. Here, we present the examples and explanations for the checklist items included ...

Potential For Meta-Analysis In The Realm Of Preharvest Food Safety, Jan M. Sargeant, Annette M. O'Connor

Veterinary Diagnostic and Production Animal Medicine Publications

Meta-analysis, the statistical combination of results from multiple studies, can be used to summarize all of the available research on an intervention, etiology, descriptive, or diagnostic test accuracy question. Meta-analysis should be conducted as a component of a systematic review, to increase transparency in the selection of studies and to incorporate an evaluation of the risk of bias in the individual studies included in the meta-analysis. The process of meta-analysis may include a forest plot to graphically display the study results and the calculation of a weighted average summary effect size. Heterogeneity (differences in the effect size between studies) can ...

Social Deprivation Of Infant Rhesus Monkeys Alters The Chemoarchitecture Of The Brain: I. Subcortical Regions, Lee J. Martin, Dawn M. Spicer, Mark H. Lewis, John P. Gluck, Linda C. Cork

John P. Gluck, Ph.D.

Rhesus monkeys (Macaca mulatta) reared during the first year of life without social contact develop persistent stereotyped movements, self-directed behaviors, and psychosocial abnormalities, but neurobiological mechanisms underlying the behaviors of socially deprived (SD) monkeys are unknown. Monkeys were reared in total social deprivation for the first 9 months of life; control monkeys were reared socially (SR) with mothers and peers. Subjects were killed at 19-24 yr of age. Because the behaviors of SD monkeys are reminiscent of changes in striatal or amygdalar function, we used immunocytochemistry for substance P (SP), leutine-enkephalin (LENK), somatostatin, calbindin, and tyrosine hydroxylase (TH) to evaluate ...

The Relationship Between Canine Nasal Length And Second-Hand Smoke Cotinine Levels, Sierra Wilson, Terry Derting 2016 Murray State University

The Relationship Between Canine Nasal Length And Second-Hand Smoke Cotinine Levels, Sierra Wilson, Terry Derting

Scholars Week

Second-hand smoke (SHS) has been associated with respiratory cancers in canines, with the predisposed locations determined by the cephalic ratio (head length / head width). Exposure to SHS is frequently measured by analyzing urine or blood samples for the nicotine by-product cotinine. We investigated the suitability of saliva as an alternative source for cotinine analyses in dogs because obtaining saliva is less invasive and cotinine concentrations from SHS exposure are instantaneously measurable in saliva compared to other collection methods. Specifically, we tested for a quantitative relationship between cephalic ratio and the salivary concentration of cotinine. Our null hypothesis was that there ...
