Two Major Ontario Hospital Labs Bought Research Dogs From U.S. Breeder With Troubled Pastdogs Bred For Scientific And Medical Testing Suffer Abuse As The Scientific Industry Increasingly Turns To Alternatives For Research., Allison Hunter, Mary Beech, Sami Marshak, Kate Morano

Capstones

The purpose-bred dog breeding industry for research is little known. Each year, thousands of dogs are bred for scientific and medical testing, supplied to research facilities by a handful of major commercial breeders. But gaps in enforcement and regulation have allowed abuses to persist, even as the industry increasingly turns to alternatives to animal testing. Animal rights advocates have been decrying the treatment of these dogs. A federal Inspector General report found lax oversight of the industry, raising further concerns about how dogs are treated. This story was reported in collaboration with the Investigative Journalism Bureau, based in Toronto, and …

The Thai Journal of Veterinary Medicine

This study aimed to investigate the computed tomography (CT) features of mast cell tumors (MCTs) and soft tissue sarcomas (STSs) in subcutaneous masses of dogs and to identify distinguishing characteristics between these two tumor types. This retrospective, multicenter study included 22 dogs with subcutaneous masses diagnosed as MCTs (n = 11) or STSs (n = 11) via fine needle aspiration or excisional biopsy. The CT features were evaluated based on four categories: location, morphological characteristics (including shape, margin, capsulation, size, and long axis to short axis (L/S) ratio of the lesion), internal parenchymal characteristics (including cavitation, vascularization, mineralization, homogeneity and …

Polyphenols For The Mitigation Of Vascular Calcification; In Vitro And In Vivo Studies, Abdullah Altuhami

All Theses

Globally, cardiovascular diseases, in most cases associated with calcification, are the main cause of death. However, currently, the only effective cure is to undergo surgery to augment or receive a healthy donor heart, which could be very difficult due to the long waiting list and the associated risks. The possibility of body rejection of the foreign organs is attributed to immunoreaction or the risk of infection, since the donor must be on immunosuppressant drugs that lower the body's immunity and facilitate the body's acceptance of the new organ as one of its own. Taking that into consideration, using tissue-engineered vascular …

Binary logistic regression models were used to …

Diagnosis, Treatment, Genetic Basis, And Prevention Of Canine Hip Dysplasia, Nathaniel R. Woody

Senior Honors Theses

Canine Hip Dysplasia (CHD) is a genetic disorder that results in an improper formation of the hip joint. This results in joint laxity, which eats away at the cartilage of the acetabulum. CHD causes arthritis, making normal walking painful for dogs. CHD is the result of many different genes and mutations working together. The best way to prevent CHD in dogs is to selectively breed animals who are not genotypic for the mutation. For dogs that already carry the mutation responsible for CHD the earlier the diagnosis and treatment the better chance they have of a full pain free life …

Digestibility, Palatability, And Nutrient Composition Of Three Species Of Whole Prey In Three Species Of Snakes, Morgan R. Kienzle

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

Snakes in human care often lack diversity in the diet. Rodents account for the majority of meals, while wild snakes are consuming a varied diet composed of multiple different whole prey species. By feeding only one species of prey, the chance of nutrient deficiencies and other health concerns increases. To promote variety in the managed diet, two commercially available whole prey species (mice (Mus musculus) and chicks (Gallus spp.)) and one novel species (Seba’s short-tailed bats (Carollia perspicillata)), were analyzed for their dry matter (DM), organic matter (OM), crude protein (CP), crude fat …

Proteomic Comparison Of Canine Gallbladder Versus Hepatic Neuroendocrine Neoplasms, Nadia Richmond

LSU Master's Theses

Hepatobiliary neuroendocrine neoplasms (HBNENs) are uncommon tumors in people and dogs, and the limited understanding of their biologic behavior often poses a diagnostic and prognostic challenge in the clinical setting. Though only a low number of cases have been described in dogs, there is evidence to indicate that primary gallbladder NENs may carry a more favorable prognosis compared to primary hepatic NENs. The emergence of liquid chromatography-mass spectrometry (LC-MS) in proteomic analysis has permitted large-scale analysis of neoplastic proteomes, allowing for better understanding of tumor pathophysiology while simultaneously enabling the rapid identification of protein biomarkers. Previous work in our laboratory …

Assessing The Feasibility Of Microneedle Patches For Gnrh Immunocontraception In Mixed-Breed Dogs (Canis Familiaris), Ai-Mei Chang, Hsiao-Hui Huang, Ding-Liang Hou, Zi-Yu Lin, Mei-Chin Chen, Chen-Chih Chen, Jai-Wei Lee

The Thai Journal of Veterinary Medicine

The overpopulation of free-roaming dogs poses significant risks to endemic species, public health, and the environment through predation and disease transmission. While surgical castration is effective, it raises ethical concerns regarding animal welfare. Immuno-castration offers a humane and effective alternative for population control, but a more easily administered and cost-efficient method is needed to enable widespread vaccination efforts. In this study, we aimed to employ self-dissolving microneedle patches for a simple and potentially cost-effective immunization of a recombinant GnRH-based vaccine to control fertility. Eight mongrel dogs were randomly divided into 2 groups (n=4 each) and immunized with the recombinant GnRH-based …

The Thai Journal of Veterinary Medicine

A 2-year-old, castrated male Jindo dog presented with 6 days of penile swelling and protrusion, suggesting priapism. Blood gas was analyzed by aspirating the corpus cavernosum to differentiate the type. However, the results were ambiguous. Ultrasound and computed tomography revealed a well-encapsulated mass ventral to the urethra. Magnetic resonance imaging showed a mass (T2-hyperintense, T1-hypointense, with no contrast enhancement) located ventral to the urethra. Cytology revealed only red blood cells, confirming a hematoma. Penile hematoma mimicking priapism was diagnosed. After 11 weeks of glucocorticoid administration, the hematoma and the protruded penis resolved. This case suggests that penile hematoma can be …

The Relationship Between Periodontal Disease Of Feline And Oral Core Microbiome, Ziyao Zhou

The Thai Journal of Veterinary Medicine

The microbiome of the oral cavity is complex with the average adult harboring about 50 to 100 billion bacteria which represent about 200 predominant bacterial species. There are a large number of microbes in the oral cavity of the feline, normally beneficial to oral health and safety maintenance. However, when the balance of bacteria lost, it may occur feline stomatitis and periodontitis, which seriously endanger local oral health. Environmental implication, feeding model, age and genetic factors may be main factors affecting oral composition of microbiome. Filifactor alocis, Porphyromonas gingivals, Tannerella forsythia and their interactions are main pathogen that …
