The Thai Journal of Veterinary Medicine

Lack of activities for dogs, that is, decreased body motion and lack of opportunities to exercise, can cause dogs to become overweight. Swimming is one of the best physical exercises for a dog that has been approved by a veterinary doctor, and it provides a form of supported exercise. Almost all the muscles are required for the movement that involves improving strength, working the cardiovascular and respiratory system, and increasing the metabolic rate withoutimpact on joints. One interesting aspect of swimming is its ability for weight and serum lipid control. The effect of frequency-controlled swimming activity on a dog’s weight …

Sera or plasma (n=343) were collected from live-capture T. m. latirostris through the US Geological Survey (USGS) manatee health assessment program and serosanguinous fluid (n=10) were collected from necropsies conducted by the Marine Mammal Pathobiology Laboratory (MMPL). Additionally, serum or serosanguinous fluid samples (n=5) were collected from rehabilitated or necropsied T. m. manatus …

Regulation Of Alpha-Herpesvirus Reactivation From Latency By Stress, Insun Kook

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Bovine herpes virus 1 (BHV-1) and Herpes simplex virus 1 (HSV-1) are crucial etiological viral agent of clinical diseases. HSV-1 and BHV-1 establish latent infection in sensory neurons. Periodically, reactivation from latency occurs resulting in virus excretion and transmission. Stress increases corticosteroid levels and the incidence of HSV-1 and BHV-1 reactivation from latency. The synthetic corticosteroid, dexamethasone (DEX) mimics stress and induces BHV-1 and HSV-1 reactivation. However, molecular mechanisms by which corticosteroid mediates viral reactivation are not well understood. My dissertation has focused on elucidating events that induce BHV- 1 or HSV-1 reactivation during the early stages of stress-induced escape …

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

Elodie Briefer, PhD

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 …

The Future Of Teratology Research Is In Vitro, Jarrod Bailey, Andrew Knight, Jonathan Balcombe

Jarrod Bailey, PhD

Birth defects induced by maternal exposure to exogenous agents during pregnancy are preventable, if the agents themselves can be identified and avoided. Billions of dollars and manhours have been dedicated to animal-based discovery and characterisation methods over decades. We show here, via a comprehensive systematic review and analysis of this data, that these methods constitute questionable science and pose a hazard to humans. Mean positive and negative predictivities barely exceed 50%; discordance among the species used is substantial; reliable extrapolation from animal data to humans is impossible, and virtually all known human teratogens have so far been identified in spite …

Animal Carcinogenicity Studies: Implications For The Reach System, Andrew Knight, Jarrod Bailey, Jonathan Balcombe

Jarrod Bailey, PhD

The 2001 European Commission proposal for the Registration, Evaluation and Authorisation of Chemicals (REACH) aims to improve public and environmental health by assessing the toxicity of, and restricting exposure to, potentially toxic chemicals. The greatest benefits are expected to accrue from decreased cancer incidences. Hence the accurate identification of chemical carcinogens must be a top priority for the REACH system. Due to a paucity of human clinical data, the identification of potential human carcinogens has conventionally relied on animal tests. However, our survey of the US Environmental Protection Agency’s (EPA’s) toxic chemicals database revealed that, for a majority of the …

Animal Carcinogenicity Studies: 1. Poor Human Predictivity, Andrew Knight, Jarrod Bailey, Jonathan Balcombe

Jarrod Bailey, PhD

The regulation of human exposure to potentially carcinogenic chemicals constitutes society’s most important use of animal carcinogenicity data. Environmental contaminants of greatest concern within the USA are listed in the Environmental Protection Agency’s (EPA’s) Integrated Risk Information System (IRIS) chemicals database. However, of the 160 IRIS chemicals lacking even limited human exposure data but possessing animal data that had received a human carcinogenicity assessment by 1 January 2004, we found that in most cases (58.1%; 93/160), the EPA considered animal carcinogenicity data inadequate to support a classification of probable human carcinogen or non-carcinogen. For the 128 chemicals with human or …

Cancerous Contradictions: The Mis-Regulation Of Human Carcinogens Based On Animal Data, Andrew Knight, Jarrod Bailey, Jonathan Balcombe

Jarrod Bailey, PhD

The regulation of human exposures to potential carcinogens constitutes society’s most important use of animal carcinogenicity data. However, for environmental contaminants of greatest U.S. concern, we found that in most cases (58.1%; 93/160) the U.S. Environmental Protection Agency (EPA) considered the animal data inadequate to support a classification of probable human carcinogen or noncarcinogen.

The World Health Organisation’s International Agency for Research on Cancer (IARC) is a leading international authority on carcinogenicity assessments. For chemicals lacking human exposure data (the great majority), IARC classifications of identical chemicals were significantly more conservative than EPA classifications (p

Histomonas meleagridis (H. meleagridis) is a protozoan parasite that may cause histomoniasis, a disease of special importance to the poultry industry and public health. The molecular characterization of H. meleagridis in China has not been established. The 5.8S and flanking ITS regions were amplified by polymerase chain reaction from 15 liver samples of chickens which were preliminarily diagnosed with H. meleagridis infection by observing clinical symptoms and macroscopic changes in the organs in Eastern China between 2012 and 2013. The obtained sequences were aligned and compared with other known sequences of H. meleagridis and related protozoan species based on ITS1-5.8S …

Rna Interference Targeting Glycoprotein D Inhibits Infectious Bovine Rhinotracheitis Virus Replication In Mdbk Cells, Lingling Song, Hui Zhang, Hongmei Wang, Peili Hou, Xianzhu Xia, Hongbin He

The Thai Journal of Veterinary Medicine

Infectious bovine rhinotracheitis (IBR) is an acute, febrile, contagious disease caused by infectious bovine rhinotracheitis virus (IBRV). IBRV vaccine is considered to be partially effective but not yet completely successful. Therefore, establishing a new antiviral approach is critical. RNA interference (RNAi) has been rapidly developed in recent years as an antiviral therapy for several viruses. This study showed that RNAi could suppress IBRV replication via knockdown of a virion glycoprotein. Two recombinant lentiviral vectors containing short hairpin RNAs (shRNAs) (H1-RNA-121, H1-RNA-304) against the glycoprotein gD of IBRV and a pcDNA3-gD vector containing a FLAG tag were constructed. pcDNA3-gD and the …

Evidence Of Kisspeptin Receptor Expression In Gnrh Neurons In The Preoptic Area And Arcuate Hypothalamic Nuclei In Cycling Buffaloes, Thuchadaporn Chaikhun-Marcou, Pongsiwa Sotthibandhu, Victoria Kyle, Shel Hwa Yeo, William Henry Colledge, Siriwat Suadsong

The Thai Journal of Veterinary Medicine

Our previous study reported the expression of kisspeptin in the preoptic area (POA) and arcuate nucleus (ARC) of the hypothalamus of cycling buffalo cows. In ruminants, POA and ARC are the main hypothalamic nuclei through which kisspeptin acts on the hypothalamic-pituitary-gonadal axis, due to their stimulation of gonadotropin releasing hormone (GnRH) secretion. In many species, kisspeptin activates GnRH neurons via its receptors (KISS1R or GPR54). The present study was designed to explore the expression of KISS1R by GnRH neurons in the POA and ARC hypothalamic nuclei in buffalo cow brains by double-labeling immunohistochemistry. In both the POA and ARC areas, …
