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 grading …

Tissue Restricted Splice Junctions Originate Not Only From Tissue-Specific Gene Loci, But Gene Loci With A Broad Pattern Of Expression, Matthew S. Hestand, Zheng Zeng, Stephen J. Coleman, Jinze Liu, James N. Macleod

Maxwell H. Gluck Equine Research Center Faculty Publications

Cellular mechanisms that achieve protein diversity in eukaryotes are multifaceted, including transcriptional components such as RNA splicing. Through alternative splicing, a single protein-coding gene can generate multiple mRNA transcripts and protein isoforms, some of which are tissue-specific. We have conducted qualitative and quantitative analyses of the Bodymap 2.0 messenger RNA-sequencing data from 16 human tissue samples and identified 209,363 splice junctions. Of these, 22,231 (10.6%) were not previously annotated and 21,650 (10.3%) were expressed in a tissue-restricted pattern. Tissue-restricted alternative splicing was found to be widespread, with approximately 65% of expressed multi-exon genes containing at least one tissue-specific splice junction. …

Jackson, Merlin D. Lindemann, James A. Boling, James C. Matthews

Animal and Food Sciences Faculty Publications

Previously, we reported the effects of fescue toxicosis on developing Angus-cross steer growth, carcass, hepatic mRNA, and protein expression profiles of selected serum proteins, and blood clinical and chemical profiles, after summer-long grazing (85 days) of high endophyte (HE)- vs. low endophyte (LE)-infected fescue pastures. We now report the temporal development of acute, intermediate, and chronic responses of biochemical and clinical blood analytes determined at specified time intervals (period 1, day 0–36; period 2, day 37–58; and period 3, day 59–85). Throughout the trial, the alkaloid concentrations of the HE forage was consistently 19–25 times greater (P ≤ 0.002) …

Autonomic Nervous System Reactivity In A Free-Ranging Mammal: Effects Of Dominance Rank And Personality, Elodie F. Briefer, James A. Oxley, Alan G. Mcelligott

Ethology Collection

Modulation of the autonomic nervous system (ANS) activity allows animals to effectively respond to internal and external stimuli in everyday challenges via changes in, for example, heart and respiration rate. Various factors, ranging from social such as dominance rank to internal such as personality or affective states can impact animal physiology. Our knowledge of the combinatory effects of social and internal factors on ANS basal activity and reactivity, and of the importance that each factor has in determining physiological parameters, is limited, particularly in nonhuman, free-ranging animals. In this study, we tested the effects of dominance rank and personality (assessed …

Evaluation Of Bacillus Spp Candidates For Aflatoxin B1 Biodegradation In Broiler Chickens, Rosario Galarza Seeber

Graduate Theses and Dissertations

Poultry health has been traditionally maintained by hygenic measures, vaccinations, and the use of antibiotics. Modern husbandry management considers the use of probiotics as a natural way to protect birds against many everyday pathogens. Different strains of Bacillus spp. have proved to have beneficial effects in poultry production. However, the most used bacterium in commercial probiotics is Lactobacillus, a vegetative cell. In contrast, Bacillus spp are bacterial spores, highly resistant to harsh conditions, which makes them preferable, in some cases, to Lactobacillus because of shelf life and storage conditions. There is published information regarding mycotoxin detoxification by bacteria. Mycotoxins are …

A Synthetic Porcine Reproductive And Respiratory Syndrome Virus Strain Confers Unprecedented Levels Of Heterologous Protection, Hiep Vu, Fangrui Ma, William W. Laegreid, Asit K. Pattnaik, David Steffen, Alan R. Doster, Fernando Osorio

School of Veterinary and Biomedical Sciences: Faculty Publications

Current vaccines do not provide sufficient levels of protection against divergent porcine reproductive and respiratory syndrome virus (PRRSV) strains circulating in the field, mainly due to the substantial variation of the viral genome. We describe here a novel approach to generate a PRRSV vaccine candidate that could confer unprecedented levels of heterologous protection against divergent PRRSV isolates. By using a set of 59 nonredundant, full-genome sequences of type 2 PRRSVs, a consensus genome (designated PRRSV-CON) was generated by aligning these 59 PRRSV full-genome sequences, followed by selecting the most common nucleotide found at each position of the alignment. Next, the …

Induction Of Parturition In Sows, Roy N. Kirkwood

The Thai Journal of Veterinary Medicine

When levels of neonatal mortality are considered too high or there is a need for relatively high levels of cross fostering, a protocol of induced farrowing should be implemented to facilitate farrowing supervision. Before implementing an induction protocol the normal gestation length for the farm should be established and sows not induced more than 2 days in advance. Earlier injections will result in low birthweight pigs with potentially compromised lung development. For optimal induction, inject prostaglandin or an analogue into the vulva at the label or 50% dose in the morning and again 6 to 8 hours later. Do not …

Reproductive Effects Of Pg600 In Female Pigs, Narathon Innamma, Attaporn Roongsitthichai

The Thai Journal of Veterinary Medicine

PG600 is a synthetic gonadotropin comprising 400 IU equine chorionic gonadotropin (eCG) and 200 IU human chorionic gonadotropin (hCG). Major responsibilities of PG600 were to stimulate follicle growth and induce ovulation. In replacement gilts, a number of large follicles were found after PG600 treatment. Nevertheless, the number of good quality follicles was not different between treatment and control gilts. In primiparous sows, the number of those returning to estrus within 10 days after weaning from PG600 were higher than those in control group. In addition, the administration of PG600 enhanced the number of piglets born alive per litter in the …
