Approaches To Canine Health Surveillance, Dan G. O'Neill, David B. Church, Paul D. Mcgreevy, Peter C. Thomson, Dave C. Brodbelt

Epidemiology Collection

Effective canine health surveillance systems can be used to monitor disease in the general population, prioritise disorders for strategic control and focus clinical research, and to evaluate the success of these measures. The key attributes for optimal data collection systems that support canine disease surveillance are representativeness of the general population, validity of disorder data and sustainability. Limitations in these areas present as selection bias, misclassification bias and discontinuation of the system respectively. Canine health data sources are reviewed to identify their strengths and weaknesses for supporting effective canine health surveillance. Insurance data benefit from large and well-defined denominator populations …

Evidence Of Positive Selection In Mitochondrial Complexes I And V Of The African Elephant., Tabitha M. Finch, Nan Zhao, Dmitry Korkin, Katy H. Frederick, Lori S. Eggert

CVM Publications

As species evolve, they become adapted to their local environments. Detecting the genetic signature of selection and connecting that to the phenotype of the organism, however, is challenging. Here we report using an integrative approach that combines DNA sequencing with structural biology analyses to assess the effect of selection on residues in the mitochondrial DNA of the two species of African elephants. We detected evidence of positive selection acting on residues in complexes I and V, and we used homology protein structure modeling to assess the effect of the biochemical properties of the selected residues on the enzyme structure. Given …

School of Veterinary and Biomedical Sciences: Faculty Publications

It is generally accepted that CD8 T cells play the key role to maintain HSV-1 latency in trigeminal ganglia of ocularly infected mice. Yet, comparably little is known about the role of innate immunity in establishment of viral latency. In the current study, we investigated whether CD8α DCs impact HSV-1 latency by examining latency in the trigeminal ganglia (TG) of wildtype (WT) C57BL/6 versus CD8α^‒/‒ (lack functional CD8 T cells and CD8α⁺ DCs), CD8β^‒/‒ (have functional CD8α⁺ T cells and CD8α⁺ DCs), and β2m^‒/‒ (lack functional CD8 T cells but have CD8α^{+ …}

The Role Of Sirtuin 1 And Ceramide In T10C12 Conjugated Linoleic Acid Induced Delipidation In 3t3-L1 Adipocytes, Wei Wang

Department of Animal Science: Dissertations, Theses, and Student Research

Project 1: Trans-10, cis-12 conjugated linoleic acid (t10c12 CLA) reduces triglyceride (TG) levels in adipocytes through multiple pathways, with AMP-activated protein kinase (AMPK) generally facilitating, and peroxisome proliferator-activated receptor γ (PPARγ) generally opposing these reductions. Sirtuin 1 (SIRT1), a histone/protein deacetylase that affects energy homeostasis, often functions coordinately with AMPK, and is capable of binding to PPARγ, thereby inhibiting its activity. This study investigated the role of SIRT1 in the response of 3T3-L1 adipocytes to t10c12 CLA by testing the following hypotheses: 1) SIRT1 is functionally required for robust TG reduction; …

Overexpression Of Thioredoxin Binding Protein (Tbp-2) Increases Oxidation Sensitivity And Apoptosis In Human Lens Epithelial Cells, Yibo Yu, Kuiyi Xing, Rilwan Badamas, Charles A. Kuszynski, Hongli Wuand, Marjorie F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

Thioredoxin (Trx) is an important redox regulator with cytosolic Trx1 and mitochondrial Trx2 isozymes. Trx has multi-physiological functions in cells and its bioavailability is negatively controlled through active site binding to a specific thioredoxin binding protein (TBP-2). This paper describes the delicate balance between TBP-2 and Trx, and the effect of overexpression of TBP-2 in the human lens epithelial cells. Cells overexpressing TBP-2 (TBP-2 OE) showed a 7- fold increase of TBP-2, and a nearly 40% suppression of Trx activity but no change in Trx expression. The TBP-2 OE cells grew slower and their population decreased to 30% by day …

Veterinary and Biomedical Sciences Faculty Publications

We have recently reported the isolation of a novel virus, provisionally designated C/swine/Oklahoma/1334/2011 (C/OK), with 50% overall homology to human influenza C viruses (ICV), from a pig in Oklahoma. Deep RNA sequencing of C/OK virus found a matrix 1 (M1) protein expression strategy that differed from that of ICV. The novelty of C/OK virus prompted us to investigate whether C/OK virus could exist in a nonswine species. Significantly, we found that C/OK virus was widespread in U.S. bovine herds, as demonstrated by reverse transcription (RT)-PCR and serological assays. Genome sequencing of three bovine viruses isolated from two herds in different …

Prevalence Of Disorders Recorded In Dogs Attending Primary-Care Veterinary Practices In England, Dan G. O'Neill, David B. Church, Paul D. Mcgreevy, Peter C. Thomson, Dave C. Brodbelt

Epidemiology Collection

Purebred dog health is thought to be compromised by an increasing occurence of inherited diseases but inadequate prevalence data on common disorders have hampered efforts to prioritise health reforms. Analysis of primary veterinary practice clinical data has been proposed for reliable estimation of disorder prevalence in dogs. Electronic patient record (EPR) data were collected on 148,741 dogs attending 93 clinics across central and south-eastern England. Analysis in detail of a random sample of EPRs relating to 3,884 dogs from 89 clinics identified the most frequently recorded disorders as otitis externa (prevalence 10.2%, 95% CI: 9.1–11.3), periodontal disease (9.3%, 95% CI: …

Relationship Between Rr And Qt Intervals In Normal And Pacing-Induced Heart Failure Dogs, Vudhiporn Limprasutr, Nakkawee Saengklub, Suwanakiet Sawangkoon, Chollada Buranakarl, Narongsak Chaiyabutr, Anusak Kijtawornrat

The Thai Journal of Veterinary Medicine

This study was conducted to determine the effects of rapid ventricular pacing on cardiac function and hemodynamics, and to determine the most suitable QTc formula for the effects of alterations in the RR interval on the QT interval of conscious dog with heart failure (HF). Electrocardiograms were acquired from dogs (n=18) at baseline and after rapid ventricular pacing (6, 9, 12 weeks). RR and QT intervals were measured and QTc intervals were calculated using 3 common formulae (Bazett, Fridericia and Van de Water). HF was confirmed by reduced left ventricular fractional shortening (p<0.05), significantly faster heart rate (p<0.001) and significantly changed QT and QTc intervals (p<0.001) when compared to the baseline. This model also demonstrated decreased systolic arterial pressure (p<0.01) and increased BNP (p<0.05). The appropriate regression equations were QT = 152.4+0.08RR for normal dogs and QT = 32.3 (RR) 0.29 for HF dogs. In normal dogs, the Van de Water formula reveals the least dependency of QTc on RR interval. In HF dogs, the Fridericia formula appears to be the best equation to remove the influence of heart rate.
