Protein Expression Of G-Protein Inwardly Rectifying Potassium Channels (Girk) In Breast Cancer Cells, Madhu S. Dhar, Howard K. Plummer

Faculty Publications and Other Works -- Large Animal Clinical Sciences

Background

Previous data from our laboratory has indicated that a functional link exists between the G-protein-coupled inwardly rectifying potassium (GIRK) channel and the beta-adrenergic receptor pathway in breast cancer cell lines, and these pathways were involved in growth regulation of these cells. Alcohol is an established risk factor for breast cancer and has been found to open GIRK. In order to further investigate GIRK channels in breast cancer and possible alteration by ethanol, we identified GIRK channel protein expression in breast cancer cells.

Results

Cell pellets were collected and membrane protein was isolated to determine GIRK protein expression. GIRK protein …

Disease Risks Associated With Increasing Feral Swine Numbers And Distribution In The United States, Thomas Hutton, Thomas J. Deliberto, Sheldon Owen, Bruce Morrison

Michigan Bovine Tuberculosis Bibliography and Database

Feral hogs or “wild boars” come from several sources and include released or escaped domestic swine and the truly wild European boar. When free-roaming in North America, all are included in the term “feral swine,” as are hybrids of the two types. Although morphologically distinct, both the feral swine and European wild swine are recognized as Sus scrofa. The physical damage caused by feral swine has been well documented and includes damage to vehicles, vineyards, tree plantings, archaeological sites, agricultural crops, turf, soils, rare plant communities, and wildlife habitat (Seward et al. 2004). In addition they compete with livestock …

The Ethics Of Referral, Bernard Rollin

Professional Veterinary Ethics Collection

The rapid growth of veterinary specialty practices has created a number of vexatious ethical issues relevant to veterinary medicine. The preeminent question pertains to “the duty to refer.” Do primary care practitioners have such a moral duty? If so, when does this duty arise? Does it pertain in all cases where specialized knowledge is relevant to a disease?

This raises the fundamental question of “Veterinary Ethics” — namely, does the veterinarian ideally have primary obligation to the client/owner or the animal? (1) There are 2 possible ideal types that a veterinarian can aim for — the Garage Mechanic Model or …

Visualization Of Intracellular Transport Of Vesicular Stomatitis Virus Nucleocapsids In Living Cells, Subash C. Das, Debasis Nayak, You Zhou, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The phosphoprotein (P) of vesicular stomatitis virus (VSV) is a subunit of the viral RNA polymerase. In previous studies, we demonstrated that insertion of 19 amino acids in the hinge region of the protein had no significant effect on P protein function. In the present study, we inserted full-length enhanced green fluorescent protein (eGFP) in frame into the hinge region of P and show that the fusion protein (PeGFP) is functional in viral genome transcription and replication, albeit with reduced activity. A recombinant vesicular stomatitis virus encoding PeGFP in place of the P protein (VSV-PeGFP), which possessed reduced growth kinetics …

Significance Of Heat-Stable And Heat-Labile Enterotoxins In Porcine Colibacillosis In An Additive Model For Pathogenicity Studies, Weiping Zhang, Emil M. Berberov, Jessica Freeling, D. He, Rodney A. Moxley, David H. Francis

School of Veterinary and Biomedical Sciences: Faculty Publications

Although heat-stable (ST) and heat-labile (LT) enterotoxins produced by enterotoxigenic Escherichia coli (ETEC) have been documented as important factors associated with diarrheal diseases, investigations assessing the contributions of individual enterotoxins to the pathogenesis of E. coli infection have been limited. To address the individual roles of enterotoxins in the diarrheal disease caused by K88-positive ETEC in young pigs, enterotoxin-positive and -negative isogenic E. coli strains were constructed by using pBR322 to clone and express LT and STb. Four strains, K88⁺ astA, K88⁺ astA/pBR322, K88⁺ astA STb⁺, and K88⁺ astA LT⁺, were constructed …

One hundred and twenty 1-day-old-malelayer chickens were raised in separate isolation rooms and equally allocated into 4 separated groups. When 4 weeks old, groups 1, 2, 3 and 4 served as a negative control, a MG commercially inactivated vaccine group, a MG commercially live vaccine group and a MG infected group, respectively. In each group, ten birds were swabbed and bled when 4, 5, 6, 7, 8, 9 and 11 weeks old. Swab samples were …

Oral Medication With Florfenicol For Black Tiger Shrimps Penaeus Monodon, Nutcharnart Tipmongkolsilp, Yanin Limpanon, Benjamas Patamalai, Pischa Lusanandana, Janenuj Wongtavatchai

The Thai Journal of Veterinary Medicine

Florfenicol (FF) and Chloramphenicol (CAP) were tested for their in vitro antimicrobial activity against 102 Vibrio isolates from clinical cases. The Minimum Inhibitory Concentration (MIC) for both antimicrobials was ≤ 8 μg/ml suggesting that all of the tested isolates were susceptible to both antimicrobials. The observed MIC range of FF (0.5-4.0 μg/ml) was more potent than that of CAP (0.5-8.0 μg/ml). The activity of both antimicrobials was not substantially influenced by the addition of sea water (5 ppt salinity) to the test system. When considering the best type of antimicrobial for food producing animals and in vitro antivibrio activity, FF …

The Zoonotic Potential Of Enterocytozoon Bieneusi In Thailand, Mathirut Mungthin, Ittisak Subrungruang, Saovanee Leelayoova

The Thai Journal of Veterinary Medicine

Enterocytozoon bieneusi is the most common microsporidia that causes disease in immunocompromised hosts, especially in AIDS patients. E. bieneusi has been reported in a wide range of animals, including domestic, wild and farm animals. Using molecular typing and phylogenetic analysis, the zoonotic potential of E. bieneusi to cause disease is indeed a threat. Transmission from animals to humans should be investigated and whether it occurs naturally, before we can address the whole subject of zoonotic transmission of E. bieneusi infection.

A Comparative Study Of Steroid Hormone Levels And Oestrogen Receptor Alpha (Erα) Between Normal Bitch Uteri And Pyometra During Dioestrus, Sayamon Srisuwatanasagul, Kongkiat Srisuwatanasagul, Sudson Sirividayapong

The Thai Journal of Veterinary Medicine

Ovarian steroid hormones and their receptors play an important role in both physiological as well as pathological changes seen in the uterus. For the further understanding of the mechanism of pyometra, in relation to steroid hormones and their receptors in the bitch, the difference between the expression of the oestrogen receptor alpha (ERa) between normal and pyometra bitches during dioestrus was investigated. Uterine samples were collected during dioestrus from normal and pyometra bitches. Immunohistochemistry was used to investigate the expression of ERa in the different compartments of the uterus. The results showed that the levels of steroid hormones in the …

Herpes Simplex Virus Type 1 Icp0 Localizes In The Stromal Layer Of Infected Rabbit Corneas And Resides Predominantly In The Cytoplasm And/Or Perinuclear Region Of Rabbit Keratocytes, Naoyuki Morishige, James V. Jester, Julie Naito, Nelson Osorio, Andrew Wahlert, Clinton J. Jones, Roger D. Everett, Steven L. Weschler, Guey Chuen Perng

School of Veterinary and Biomedical Sciences: Faculty Publications

Herpes stromal keratitis (HSK) results from the reactivation of herpes simplex virus type-1 (HSV-1) in the cornea. The subsequent corneal inflammation and neovascularization may lead to scarring and visual loss. The cellular and molecular mechanisms underlying HSK remain unknown. The presence of stromal HSV-1 viral proteins or antigens in the HSK cornea remains a subject of debate. It was recently reported that HSV-1 ICP0 rapidly diffuses out of infected rabbit corneas. To investigate further the presence of HSV-1 ICP0 in the infected cornea, particularly in the corneal stroma, ex vivo confocal microscopy was used to scan rabbit corneas infected with …

Las patologías cardiacas son afecciones que comprometen el funcionamiento normal del corazón y de otros órganos del cuerpo, desencadenando problemas sistémicos que pueden llevar a la muerte del paciente a largo plazo. Debido a que son pocos los estudios de laboratorio que han valorado los electrolitos, la osmolaridad y la fracción de excreción renal de sodio en las diferentes etapas de la enfermedad cardiaca, en este proyecto se determinó la osmolaridad y la fracción de excreción de sodio buscando una posible correlación con la fracción de acortamiento ventricular en pacientes con patologías cardiacas y con esto desarrollar modelos de evaluación …

Does Diving Limit Brain Size In Cetaceans?, Lori Marino, Daniel Sol, Kristen Toren, Louis Lefebvre

Veterinary Science and Medicine Collection

We test the longstanding hypothesis, known as the dive constraint hypothesis, that the oxygenation demands of diving pose a constraint on aquatic mammal brain size.Using a sample of 23 cetacean species we examine the relationship among six different measures of relative brain size, body size, and maximum diving duration. Unlike previous tests we include body size as a covariate and perform independent contrast analyses to control for phylogeny. We show that diving does not limit brain size in cetaceans and therefore provide no support for the dive constraint hypothesis. Instead, body size is the main predictor of maximum diving duration …

Bovine Herpesvirus 1 Immediate-Early Protein (Bicp0) Interacts With The Histone Acetyltransferase P300, Which Stimulates Productive Infection And Gc Promoter Activity, Yange Zhang, Yunquan Jiang, Vicki Geiser, Joe Zhou, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

The immediate-early protein, bICP0, of Bovine herpesvirus 1 (BHV-1) transactivates viral promoters and stimulates productive infection. bICP0 is expressed constitutively during productive infection, as its gene contains an immediate- early and an early promoter. Like other ICP0 homologues encoded by members of the subfamily Alphaherpesvirinae, bICP0 contains a zinc RING finger located near its N terminus. Mutations that disrupt the bICP0 zinc RING finger impair its ability to activate transcription, stimulate productive infection, inhibit interferon-dependent transcription in certain cell types and regulate subnuclear localization. bICP0 also interacts with a cellular chromatin-remodeling enzyme, histone deacetylase 1 (HDAC1), and can relieve …

Effects Of Moraxella (Branhamella) Ovis Culture Filtrates On Bovine Erythrocytes, Peripheral Mononuclear Cells, And Corneal Epithelial Cells, Henry E. Cerny, Douglas G. Rogers, Jeffrey T. Gray, David R. Smith, Susanne Hinkley

School of Veterinary and Biomedical Sciences: Faculty Publications

Infectious bovine keratoconjunctivitis (IBK) is a highly contagious ocular disease that affects cattle of all ages and that occurs worldwide. Piliated hemolytic Moraxella bovis is recognized as the etiologic agent of IBK. According to data from the Nebraska Veterinary Diagnostic Laboratory System, however, Moraxella (Branhamella) ovis has been isolated with increasing frequency from cattle affected with IBK. The objective of this study was, therefore, to examine M. ovis field isolates for the presence of the putative virulence factors of M. bovis. Culture filtrates from selected M. ovis field isolates demonstrated hemolytic activity on bovine erythrocytes and cytotoxic activity on …

The Thai Journal of Veterinary Medicine

Malignant catarrhal fever (MCF) is a highly fatal disease of ruminants which has not been extensively studied in Thailand. The aim of this study was to describe the clinical signs and pathological findings of MCFaffected buffaloes (n = 13), in the Nakhonpathom province of Thailand. All cases were collected between May 1996 and August 2000. Before the 1998 outbreak, four clinically normal sheep were moved into a pen adjacent to the buffaloes’ pens. The animals developed clinical signs of severe depression, anorexia, high fever, hypersalivation, and corneal opacity-associated excessive lacrimation. Necropsy revealed severe haemorrhages in various organs including the oropharynx, …
