Pathology And Osteological Observations Of Early Pliocene Rhinoceros, Teleoceras Aepysoma (Perissodactyla, Rhinocerotidae) From Gray Fossil Site, Tennessee, Thomas Scaife

Electronic Theses and Dissertations

Rhinoceroses were an important part of North America’s Paleogene and Neogene ecosystems, with Teleoceras aepysoma being one of the last representatives of this family. Specimens of T. aepysoma from the Gray Fossil Site (GFS) possess distinct/peculiar pathologies: including a pair of fused ribs and ankylosed phalanges. A qualitative description of the pathologies in the GFS T. aepysoma, including new material, was conducted to accurately identify pathologies and make interpretations about the life history of the GFS rhinos. Analysis suggests that rheumatoid arthritis is common in the lower limb bones of GFS rhinos. Additionally, the rib and toe pathologies are more …

Pathological, Ultrastructural And Haematological Studies On The Simultaneous Effect Of Dietary Supplementation With Lauric And Benzoic Acids On Nile Tilapia, Abdelaziz M. Rabea, Iman Ibrahim, Hebatallah A. Mahgoub, Ahmed El- Shaieb

Mansoura Veterinary Medical Journal

Objective: To evaluate the simultaneous effect of dietary acidifier lauric and benzoic acids on immunohematological parameters and histopathological changes in O. niloticus.

Design: Randomized controlled study.

Animal Models: The experiment was performed on 120 juvenile Nile tilapia weighing (50 ± 6.14 g).

Procedures: Fish were divided into four experimental groups (30 fish/group): Control group received normal diet; Benzoic Acid group was supplemented with benzoic acid 1 g/kg diet); Lauric Acid group was supplemented with lauric acid (1 g/kg diet); combination group was supplemented with benzoic acid (1 g/kg diet) and lauric acid (1 g/kg diet). Supplements were applied for 30 …

Type X Strains Of Toxoplasma Gondii Are Virulent For Southern Sea Otters (Enhydra Lutris Nereis) And Present In Felids From Nearby Watersheds, Karen Shapiro, Elizabeth Vanwormer, Andrea Packham, Erin Dodd, Patricia A. Conrad, Melissa Miller

School of Veterinary and Biomedical Sciences: Faculty Publications

Why some Toxoplasma gondii-infected southern sea otters (Enhydra lutris nereis) develop fatal toxoplasmosis while others have incidental or mild chronic infections has long puzzled the scientific community. We assessed robust datasets on T. gondii molecular characterization in relation to detailed necropsy and histopathology results to evaluate whether parasite genotype influences pathological outcomes in sea otters that stranded along the central California coast. Genotypes isolated from sea otters were also compared with T. gondii strains circulating in felids from nearby coastal regions to assess land-to-sea parasite transmission. The predominant T. gondii genotypes isolated from 135 necropsied sea otters were atypical Type …

The Role Of Nadph Oxidase 2 (Nox2) In High-Fat Diet-Induced Adiposopathy And Brain Dysfunction In A Mouse Model, Jennifer Kathleen Pepping

LSU Master's Theses

Obesity can have numerous detrimental consequences, namely metabolic syndrome, type 2 diabetes, cardiovascular disease, cancer, and Alzheimer’s disease. The pathogenesis and physiologic consequences of obesity are unknown, but they are often associated with increased inflammation and oxidative stress in both the body and in the brain. One factor that has been implicated in causing inflammation associated with a high fat diet is the enzyme NADPH oxidase, or NOX, specifically the subunit NOX2. Two studies were performed in order to assess the effects of a high fat diet in combination with a universal NOX2 deficiency and a NOX2 deficiency targeted to …

On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The "walking disease" of Northwestern Nebraska is essentially an enzootic necrobiosis and cirrhosis of the liver due to a toxic agent and does not materially differ from similar disorders occurring in other regions or countries. The disease affects horses and cattle but it is most commonly encountered in the former. The disease in all its clinical and pathological manifestations may be reproduced with the utmost fidelity by the feeding with plants of Senecio riddellii.
