Nociception In Fish: Stimulus–Response Properties Of Receptors On The Head Of Trout Oncorhynchus Mykiss, Paul J. Ashley, Lynne U. Sneddon, Catherine R. Mccrohan

Veterinary Science and Medicine Collection

This study examined stimulus–response properties of somatosensory receptors on the head of rainbow trout, Oncorhynchus mykiss, using extracellular recording from single cells in the trigeminal ganglion. Of 121 receptors recorded from 39 fish, 17 were polymodal nociceptors, 22 were mechanothermal nociceptors, 18 were mechanochemical receptors, 33 were fast adapting mechanical receptors and 31 were slowly adapting mechanical receptors. Mechanical thresholds were higher in polymodal nociceptors than in either slowly adapting or fast adapting mechanical receptors, whereas thermal thresholds of mechanothermal nociceptors were higher than those of polymodal nociceptors. Polymodal nociceptors and mechanochemical receptors gave similar responses to topical applications of …

Rapid Phase Adjustment Of Melatonin And Core Body Temperature Rhythms Following A 6-H Advance Of The Light/Dark Cycle In The Horse, Barbara A. Murphy, Jeffrey A. Elliott, Dawn R. Sessions, Mandi M. Vick, Erin L. Kennedy, Barry P. Fitzgerald

Veterinary Science Faculty Publications

BACKGROUND: Rapid displacement across multiple time zones results in a conflict between the new cycle of light and dark and the previously entrained program of the internal circadian clock, a phenomenon known as jet lag. In humans, jet lag is often characterized by malaise, appetite loss, fatigue, disturbed sleep and performance deficit, the consequences of which are of particular concern to athletes hoping to perform optimally at an international destination. As a species renowned for its capacity for athletic performance, the consequences of jet lag are also relevant for the horse. However, the duration and severity of jet lag related …

Isotype-Specific Antibody Responses Against Escherichia Coli O157:H7 Locus Of Enterocyte Effacement Proteins In Adult Beef Cattle Following Experimental Infection, G. Bretschneider, E. M. Berberov, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Escherichia coli O157:H7 is an important food-borne pathogen and cause of hemorrhagic colitis and hemolytic uremic syndrome in humans. Cattle are an important reservoir of E. coli O157:H7, in which the organism colonizes the intestinal tract and is shed in the feces. Vaccination of cattle has significant potential as a pre-harvest intervention strategy for E. coli O157:H7; however, basic information about the bovine immune responses to important bacterial colonization factors resulting from infection has not been reported. The serum and fecal IgG and IgA antibody responses of adult cattle to E. coli O157:H7 intimin, translocated intimin receptor (Tir), E. coli …

Low Molecular Weight Protein Tyrosine Phosphatase (Lmw-Ptp) And Its Possible Physiological Functions Of Redox Signaling In The Eye Lens, Kuiyi Xing, Ashraf Raza, Stefan Lofgren, M. Rohan Fernando, Ye-Shih Ho, Marjorie F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

Low molecular weight protein tyrosine phosphatase (LMW-PTP) was cloned from human lens epithelial B3 cells (HLE B3) and the recombinant enzyme was purified to homogeneity. The pure enzyme reacted positively with anti-LMW-PTP antibody, displayed tyrosine-specific phosphatase activity and was extremely sensitive to H2O2. The inactivated LMW-PTP could be regenerated by thioltransferase (TTase)/GSH system as demonstrated by both activity assay and by mass spectrometry (MS). The MS study also showed that an intramolecular disulfide bond was formed between C13 and C18 at the active site, and was reduced by the TTase/GSH system. The putative role of LMW-PTP in regulating platelet derived …

Ethical Issues In Geriatric Feline Medicine, Bernard E. Rollin

Veterinary Science and Medicine Collection

Most veterinarians hold a ‘pediatric’ rather than ‘garage mechanic’ view of their function. In recent years, sophisticated medical modalities have allowed veterinarians to keep animals alive, and increased value of companion animals in society has increased demand for such treatment. But whereas humans can choose to trade current suffering for extended life, animals seem to lack the cognitive apparatus required to do so. Thus, veterinarians must guard against keeping a suffering animal alive for too long. Clients may be emotionally tied to the animal and blind to its suffering. Part of the veterinarian’s role, therefore, is to lead the client …

Cetacean Brains: How Aquatic Are They?, Lori Marino

Anatomy Collection

The adaptation of cetaceans to a fully aquatic lifestyle represents one of the most dramatic transformations in mammalian evolutionary history. Two of the most salient features of modern cetaceans are their fully aquatic lifestyle and their large brains. This review article will offer an overview of comparative neuroanatomical research on aquatic mammals, including analyses of odontocete cetacean, sirenian, pinniped, and fossil archaeocete brains. In particular, the question of whether a relationship exists between being fully aquatic and having a large brain is addressed. It has been hypothesized that the large, well‐developed cetacean brain is a direct product of adaptation to …

Effects Of A Beta Adrenergic Antagonist Combined With Vasodilators On Cardiac Arrhythmia In Ischemic-Induced Rat Hearts, Promporn Raksaseri, Wuthichai Klomkleaw, Suwanakiet Sawangkoon

The Thai Journal of Veterinary Medicine

Sixty male Spraque-Dawley rats were used in this study. The hearts were isolated and placed on a constant-pressure Langendorff apparatus, and perfused with only Krebs-Henseleit buffer (control), atenolol, atenolol plus prazosin, and atenolol plus salbutamol. After that the left anterior descending artery was occluded for 8 minutes and reperfused for 30 minutes to induce cardiac arrhythmias. The left ventricular pressure and coronary flow rate were monitored, and ECGs were recorded to evaluate cardiac arrhythmias. The administration of atenolol (β1-adrenergic antagonist) combined with prazosin (α1-adrenergic antagonist) prolonged RR intervals whereas that of atenolol combined with salbutamol (β2-adrenergic antagonist) did not prolong …

Prevention And Control Of Respiratory Diseases Excluding Mycoplasma Hyopneumoniae, Stanley Done, David Burch

The Thai Journal of Veterinary Medicine

Significant changes in respiratory disease have occurred over the last 20 years. There are two primary reasons for this. In the first instance, there has been the occurrence of two major worldwide plagues-PRRS and PCV2-associated diseases. The second reason has been the considerable advances in vaccination, which have become available for some of the respiratory diseases, in particular Mycoplasma hyopneumoniae. Vaccines have also become available for porcine reproductive and respiratory syndrome virus (PRRS), influenza viruses (outside UK) and probably in the near future against porcine circovirus type 2 (PCV2).

Success Rate And Postoperative Complications Of Phacoemulsification In 25 Cataractous Eyes : A Retrospective Study In 20 Dogs (2003-2005), Pasakorn Brikshavana

The Thai Journal of Veterinary Medicine

Phacoemulsification was performed on 25 eyes of 20 dogs (7 females and 13 males) with a mean patient age ± SD at the time of surgery of 8.12 ± 2.76 years (range 4-14.5 years). The medical records were reviewed for surgical outcome and postoperative complications. Success rate was calculated by determining the number of successful eyes divided by the total number of the eyes in the studied group. The results showed that restoration of functional vision was noted in 24/25 eyes at the end of the study. The success rate of this study was 96%. The most frequently observed complication …

Cetaceans Have Complex Brains For Complex Cognition, Lori Marino, Richard C. Connor, R. Ewan Fordyce, Louis M. Herman, Patrick R. Hof, Louis Lefebvre, David Lusseau, Brenda Mccowan, Esther A. Nimchinsky, Adam A. Pack, Luke Rendell, Joy S. Reidenberg, Diana Reiss, Mark D. Uhen, Estel Van Der Gucht, Hal Whitehead

Anatomy Collection

We believe that the time is ripe to present an integrated view of cetacean brains, behavior, and evolution based on the wealth of accumulated and recent data on these topics. Our conclusions support the more generally accepted view that the large brain of cetaceans evolved to support complex cognitive abilities.

A Comparison Of Pyronin Y-Methyl Green Stain And Methylene Blue Stain For Somatic Cell Count In Sheep Milk, Emily Mirek, Stacey O’Donnell

Senior Honors Projects

Somatic cell count is a key method used to evaluate the quality of milk in today’s growing dairy sheep industry. Somatic cells are body cells, primarily the white blood cells, found in a milk sample. If an infection such as mastitis is present, the number of somatic cells in the milk increases (Gonzalo, et al. 1992). Producers routinely perform somatic cell counts on cow and goat milk. For dairy cattle in the United States, the somatic cell count can not exceed 750,000 cells per milliliter, for commercial milk. For dairy goats the accepted limit is 1,000,000 cells per mL of …

Spatial And Temporal Patterns Of Enzootic Raccoon Rabies Adjusted For Multiple Covariates, Sergio Recuenco, Millicent Eidson, Martin Kulldorff, Glen Johnson, Bryan Cherry

Zoonotics and Wildlife Disease: Publications

Background: With the objective of identifying spatial and temporal patterns of enzootic raccoon variant rabies, a spatial scan statistic was utilized to search for significant terrestrial rabies clusters by year in New York State in 1997–2003. Cluster analyses were unadjusted for other factors, adjusted for covariates, and adjusted for covariates and large scale geographic variation (LSGV). Adjustments were intended to identify the unusual aggregations of cases given the expected distribution based on the observed locations.

Results: Statistically significant clusters were identified particularly in the Albany, Finger Lakes, and South Hudson areas. The clusters were generally persistent in the Albany area, …
