Glutathione And Glutaredoxin In Redox Regulation And Cell Signaling Of The Lens, Marjorie F. Lou Oct 2022

Glutathione And Glutaredoxin In Redox Regulation And Cell Signaling Of The Lens, Marjorie F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

The ocular lens has a very high content of the antioxidant glutathione (GSH) and the enzymes that can recycle its oxidized form, glutathione disulfide (GSSG), for further use. It can be synthesized in the lens and, in part, transported from the neighboring anterior aqueous humor and posterior vitreous body. GSH is known to protect the thiols of the structural lens crystallin proteins from oxidation by reactive oxygen species (ROS) so the lens can maintain its transparency for proper visual function. Age-related lens opacity or senile cataract is the major visual impairment in the general population, and its cause is closely …


Intestinal Parasite Prevalence In Fecal Samples In Nebraska Dog Parks, Kristianna Muller Oct 2022

Intestinal Parasite Prevalence In Fecal Samples In Nebraska Dog Parks, Kristianna Muller

Honors Program: Senior Projects (Public)

From February to April 2022, fecal samples were collected from eight dog parks in the Omaha and Lincoln, NE areas. A total of 160 samples were collected and assessed for the presence of intestinal parasites. The zinc sulfate double centrifugal flotation technique was used to determine infection. Out of the 160 samples, ten were positive for parasite contamination (6.25% prevalence). The most observed parasites were hookworms, found in 3.75% of all samples (6/160). Cystoisospora, Giardia, Toxocara canis, and Toxascaris leonina were all found only once, for a prevalence of 0.625% each. Compared to other studies, our infection …


The Ethical Perceptions Of Dog Tail Docking Amongst Owners And Veterinarians In South Carolina, Hannah Ellen Steinberg Oct 2022

The Ethical Perceptions Of Dog Tail Docking Amongst Owners And Veterinarians In South Carolina, Hannah Ellen Steinberg

Senior Theses

This thesis aimed to discover, in depth, what tail docking of dogs is, why it is currently in practice, what the controversial opinions surrounding it are, how the opinions differ when taking into account the professionals of the field versus owners and breeders, and how it can be addressed in the future to treat our animals as humanely as possible.

Based on the surveying of South Carolinian owners, breeders, and veterinarians, it was discovered that dog tail-docking procedures are overwhelmingly used for cosmetic or aesthetic purposes, with the aim being to match breed standards. There was a disagreement amongst those …


Seasonal Habitat Selection By American White Pelicans, Frederick L. Cunningham, Guiming Wang, D. Tommy King Sep 2022

Seasonal Habitat Selection By American White Pelicans, Frederick L. Cunningham, Guiming Wang, D. Tommy King

United States Department of Agriculture Wildlife Services: Staff Publications

Resource utilization strategies of avian migrants are a major concern for conservation and management. Understanding seasonal habitat selection by migratory birds helps us explain the ongoing continental declines of migratory bird populations. Our objective was to compare the secondorder and third-order habitat selection by the American White Pelican (Pelecanus erythrorhynchos; hereafter pelican) between the breeding and non-breeding grounds. We tested the Lack hypothesis that habitat selection by migratory birds is stronger on the breeding grounds than on the nonbreeding grounds. We used random-effect Dirichlet-multinomial models to estimate the second-order habitat selection between the seasons with the GPS locations …


Effects Of Early‑Life Experience On Innovation And Problem‑Solving In Captive Coyotes, Andrew C. Garcia, Mitchell A. Parsons, Julie K. Young Sep 2022

Effects Of Early‑Life Experience On Innovation And Problem‑Solving In Captive Coyotes, Andrew C. Garcia, Mitchell A. Parsons, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Early-life experience often shapes behaviors like innovation and exploration. These behaviors are important to animals encountering novel food resources in diverse habitats, such as mesocarnivores in urban areas. To understand if early-life experiences impact later-life behavior, we examined how coyotes (Canis latrans) responded to a multi-access puzzle box at two life stages: pup (~ 7 weeks) and dispersal (~ 10 months). We first exposed pups, still living with their parents and littermates, to a baited puzzle box. At dispersal age, we again tested both these pups and an age-matched control group that was not exposed to the puzzle …

Therapeutic Effects Of Sildenafil Combined With Low-Dosage Imatinib On Pulmonary Hypertension In Five Dogs, Yu Sahashi, Yoshiaki Hikasa

The Thai Journal of Veterinary Medicine

Five dogs were diagnosed with pulmonary hypertension (PH) secondary to chronic degenerative mitral valve disease or ventricular septal defect. They were initially administered low-dose imatinib mesylate (3 mg/kg, q24h) without changes to the background therapy to treat PH. The low-dose imatinib improved the right ventricular (RV) function parameters including estimated systolic and mean pulmonary arterial pressures (sPA and mPAP) and clinical symptoms. On day 53 to day 168 after imatinib administration, as PH and clinical signs worsened, low-dose sildenafil (0.5 mg/kg, q12h) was administered in combination with imatinib. This combination greatly reduced the estimated sPA and mPAP, and improved clinical …

A Systematic Review: The Source Of Antimicrobial Resistance Pathogenic Bacteria On Slaughtered Meat, Cross-Contamination Or Self-Contamination?, Xin Wu, Fanan Suksawat, Sunpetch Angkititrakul, Chunlian Song, Jun Chai, Yifang Zhang, Xianghua Shu, Huiyan Xing, Wengui Li Sep 2022

A Systematic Review: The Source Of Antimicrobial Resistance Pathogenic Bacteria On Slaughtered Meat, Cross-Contamination Or Self-Contamination?, Xin Wu, Fanan Suksawat, Sunpetch Angkititrakul, Chunlian Song, Jun Chai, Yifang Zhang, Xianghua Shu, Huiyan Xing, Wengui Li

The Thai Journal of Veterinary Medicine

Slaughtered meat has been identified as one of the major vehicles for forming antimicrobial resistance (AMR). It is still believed that AMR pathogens introduced by overusing antimicrobials in the breeding industry are directly brought in from farm animals. This disregards however the fact that many gut pathogens do not settle on muscle parts; the presence of gut pathogens on muscle products does not directly correlate to farm feeding. To investigate whether the source of AMR bacteria on slaughtered meat was cross-contamination or self-contamination, many peer-reviewed publications were studied to assess if the observational studies focused on AMR pathogenic bacteria association …

Odor Detection Of Cancer Cell Metabolites By Scent-Detection Dogs, Geontae Park, Dongwook Kim, Seongsoo Jeong, Dongsun Park, Gonhyung Kim Sep 2022

Odor Detection Of Cancer Cell Metabolites By Scent-Detection Dogs, Geontae Park, Dongwook Kim, Seongsoo Jeong, Dongsun Park, Gonhyung Kim

The Thai Journal of Veterinary Medicine

Dogs have a superior olfactory system; thus, they have been trained and used to detect various nonbiological and biological scents. In addition, many studies have recently reported dogs’ ability to detect the odor of certain cancers or cancer cells. A previous study documented that a dog trained to detect a certain malignant cancer cell could also detect another, unfamiliar malignant cancer cell well, implying that these two cancer cells share a certain specific odor. Thus, given the hypothesis that malignant cancer cells of different origins may contain a common cancer-specific odor, the purpose of the present study was to evaluate …

Comparison Of Biomechanical Properties Associated With The Diameter And Insertion Depth Of Bone Anchors In The Femoral Condyle Of Toy Breed Cadaver Dogs, Yun-Hee An, Mu-Young Kim, Hun-Young Yoon Sep 2022

Comparison Of Biomechanical Properties Associated With The Diameter And Insertion Depth Of Bone Anchors In The Femoral Condyle Of Toy Breed Cadaver Dogs, Yun-Hee An, Mu-Young Kim, Hun-Young Yoon

The Thai Journal of Veterinary Medicine

The objective of the present study was to compare the biomechanical properties of implanted bone anchors based on diameter and insertion depth to yield selection criteria for bone anchor size in toy breed dogs. Twenty toy breed dog cadavers weighing < 5 kg underwent placement of five types of veterinary bone anchors (short diameter, short length [SDSL]; short diameter, medium length [SDML]; medium diameter, medium length [MDML]; medium diameter, long length [MDLL]; and long diameter, medium length [LDML]) at a predetermined femoral attachment site. Anchor screw depth/femoral condyle width (FCW) and anchor screw diameter/femoral condyle length (FCL) were measured using radiography. The yield load, Young’s modulus and failure load were measured and the causes of failure for each construct were recorded. The anchor screw depth/FCW was < 50%, 50%–75%, ~50%, and 75%–100% in the SDSL, SDML, MDML, and MDLL groups, respectively. The yield load, Young’s modulus and failure load were higher in the SDML and MDLL groups than in the SDSL and MDML groups. The anchor screw diameter/FCL was 12%–15% and 24%–30% in the SDML and LDML groups, respectively. No differences in biomechanical parameters were found between the SDML and LDML groups. The cause of failure in all constructs was pull-out of the bone anchor, except for distal femur fracture in five LDML constructs. In conclusion, when implanting bone anchors in toy breed dogs, the insertion depth should be > 50% of the FCW, regardless of diameter. Moreover, distal femur fracture can occur if the bone anchor diameter/FCL ratio exceeds 24%.
