Light-Induced Fos Expression In Intrinsically Photosensitive Retinal Ganglion Cells In Melanopsin Knockout (Opn4-/-) Mice, Gary E. Pickard, Scott B. Baver, Malcolm D. Ogilvie, Patricia J. Sollars Jan 2009

Light-Induced Fos Expression In Intrinsically Photosensitive Retinal Ganglion Cells In Melanopsin Knockout (Opn4-/-) Mice, Gary E. Pickard, Scott B. Baver, Malcolm D. Ogilvie, Patricia J. Sollars

School of Veterinary and Biomedical Sciences: Faculty Publications

Retinal ganglion cells that express the photopigment melanopsin are intrinsically photosensitive (ipRGCs) and exhibit robust synaptically driven ON-responses to light, yet they will continue to depolarize in response to light when all synaptic input from rod and cone photoreceptors is removed. The light-evoked increase in firing of classical ganglion cells is determined by synaptic input from ON-bipolar cells in the proximal sublamina of the inner plexiform layer. OFF-bipolar cells synapse with ganglion cell dendrites in the distal sublamina of the inner plexiform layer. Of the several types of ipRGC that have been described, M1 ipRGCs send dendrites exclusively into the …

Ovine Progressive Pneumonia Provirus Levels Are Unaffected By The Prion 171r Allele In An Idaho Sheep Flock, Robert D. Harrington, Lynn M. Herrmann-Hoesing, Stephen N. White, Katherine I. O'Rourke, Donald P. Knowles Jan 2009

Ovine Progressive Pneumonia Provirus Levels Are Unaffected By The Prion 171r Allele In An Idaho Sheep Flock, Robert D. Harrington, Lynn M. Herrmann-Hoesing, Stephen N. White, Katherine I. O'Rourke, Donald P. Knowles

Zoonotics and Wildlife Disease: Publications

Selective breeding of sheep for arginine (R) at prion gene (PRNP) codon 171 confers resistance to classical scrapie. However, other effects of 171R selection are uncertain. Ovine progressive pneumonia/Maedi-Visna virus (OPPV) may infect up to 66% of a flock thus any affect of 171R selection on OPPV susceptibility or disease progression could have major impact on the sheep industry. Hypotheses that the PRNP 171R allele is 1) associated with the presence of OPPV provirus and 2) associated with higher provirus levels were tested in an Idaho ewe flock. OPPV provirus was found in 226 of 358 …

Validation Of Use Of Rectoanal Mucosa-Associated Lymphoid Tissue For Immunohistochemical Diagnosis Of Chronic Wasting Disease In White-Tailed Deer (Odocoileus Virginianus), Delwyn Keane, Daniel Barr, Rebecca Osborn, Julie Langenberg, Katherine I. O'Rourke, David Schneider, Phillip Bochsler

Zoonotics and Wildlife Disease: Publications

The examination of rectoanal mucosa-associated lymphoid tissue (RAMALT) biopsy specimens for the diagnosis of transmissible spongiform encephalopathies has been described in sheep, elk, and small numbers of mule and white-tailed deer. Previous sample numbers have been too small to validate examination of this type of tissue as a viable antemortem diagnostic test. In this study, we examined RAMALT collected postmortem from 76 white-tailed deer removed from a farm in Wisconsin known to be affected by chronic wasting disease (CWD) and from 210 free-ranging white-tailed deer harvested from an area in Wisconsin where the overall prevalence of CWD among the deer …

Vaccination With Mycobacterium Bovis Bcg Strains Danish And Pasteur In White-Tailed Deer (Odocoileus Virginianus) Experimentally Challenged With Mycobacterium Bovis, M. V. Palmer, T. C. Thacker, W. R. Waters

Michigan Bovine Tuberculosis Bibliography and Database

Wildlife reservoirs of Mycobacterium bovis represent serious obstacles to the eradication of tuberculosis in domestic livestock and the cause for many faltering bovine tuberculosis eradication programs. One approach in dealing with wildlife reservoirs of disease is to interrupt inter-species and intraspecies transmission through vaccination of deer or cattle. To evaluate the efficacy of BCG vaccination in white-tailed deer, 35 deer were assigned to one of three groups; one s.c. dose of 107 CFU of M. bovis BCG Pasteur (n = 12); 1 s.c. dose of 107 CFU of M. bovis BCG Danish (n = 11); or unvaccinated deer …

The Effects Of Dietary Conjugated Linoleic Acid (Cla) On Fatty Acid Composition And Key Enzymes Of Fatty Acid Oxidation In Liver And Muscle Of Geese, Xuhui Zhang, Baowei Wang, Fangyu Long, Lei Wang, Zhigang Yang Jan 2009

The Effects Of Dietary Conjugated Linoleic Acid (Cla) On Fatty Acid Composition And Key Enzymes Of Fatty Acid Oxidation In Liver And Muscle Of Geese, Xuhui Zhang, Baowei Wang, Fangyu Long, Lei Wang, Zhigang Yang

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to determine the influence of conjugated linoleic acid (CLA) on fatty acid composition and key enzymes of fatty acid oxidation in liver and muscle of geese. A total of 192 1-day-old geese were randomly assigned to 1 of 4 dietary groups, and were fed for 56 days on diets containing 2.5% soybean oil (group A, control group) or 2.0% soybean oil with 0.5% CLA (group B), 1.0% soybean oil with 1.5% CLA (group C), and 2.5 % CLA (group D). Geese fed CLA had a decreased abdominal fat percentage (AFP) (P < 0.01) compared with the control. It was observed that dietary CLA levels had a significant effect on the body weight, weight gain, feed conversion rate (FCR) (P < 0.05), and feed intake (P < 0.01). Fatty acid composition showed a significant increase of the biologically active cis-9, trans-11 and trans-10, and cis-12 CLA isomers in both liver and muscle of geese fed CLA (P < 0.01). Dietary CLA led to an increase (P < 0.01) in saturated fatty acid (SFA) and a reduction in monounsaturated fatty acid (MUFA) (P < 0.05) concentrations in both liver and muscle. In liver, dietary CLA increased (P < 0.05) acyl CoA oxidase (ACO) activity, but did not affect carnitine palmitoyltransferase-I (CPT-I) activity compared with the control. CPT-I activity was significantly increased by 2.5% dietary CLA in muscle, where ACO activity was decreased at 1.5% CLA level. The results obtained suggested that geese can successfully incorporate CLA in both liver and muscle, which could be beneficial in the human diet, through provision of bioactive fatty acids with no detrimental effects on n-3 PUFA levels.

Pathogenesis Of Influenza A Virus: Inhibition Of Monocyte Differetiation Into Dendritic Cell, Saikat Boliar Jan 2009

Pathogenesis Of Influenza A Virus: Inhibition Of Monocyte Differetiation Into Dendritic Cell, Saikat Boliar

University of Kentucky Doctoral Dissertations

Dendritic cells (DC) are a heterogeneous population of hematopoietic cells that play a versatile role in orchestrating immune responses against an array of invading pathogens, including influenza virus. These cells reside in lymphoid organs as well as in non-lymphoid tissues such as mucosal surfaces of respiratory and gastro-intestinal system. Recent investigations have suggested that in the steady state, dendritic cells are derived mainly from bone marrow precursor cells without a monocytic intermediate whereas during inflammation or infection, monocytes readily differentiate to generate monocyte derived dendritic cells (MoDC). The ability of virus infected monocytes to differentiate into MoDC was investigated and …

Pyrilamine In The Horse: Detection And Pharmacokinetics Of Pyrilamine And Its Major Urinary Metabolite O-Desmethylpyrilamine, L. Dirikolu, A. F. Lehner, J Daniel Harkins, W. E. Woods, W. Karpiesiuk, R. S. Gates, M. Fisher, Thomas Tobin Jan 2009

Pyrilamine In The Horse: Detection And Pharmacokinetics Of Pyrilamine And Its Major Urinary Metabolite O-Desmethylpyrilamine, L. Dirikolu, A. F. Lehner, J Daniel Harkins, W. E. Woods, W. Karpiesiuk, R. S. Gates, M. Fisher, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Pyrilamine is an antihistamine used in human and veterinary medicine. As antihistamines produce central nervous system effects in horses, pyrilamine has the potential to affect the performance of racehorses. In the present study, O-desmethylpyrilamine (O-DMP) was observed to be the predominant equine urinary metabolite of pyrilamine. After intravenous (i.v.) administration of pyrilamine (300 mg/horse), serum pyrilamine concentrations declined from about 280 ng/mL at 5 min postdose to about 2.5 ng/mL at 8 h postdose. After oral administration of pyrilamine (300 mg/horse), serum concentrations peaked at about 33 ng/mL at 30 min, falling to <2 ng/mL at 8 h postdose. Pyrilamine was not detected in serum samples at 24 h postdosing by either route. After i.v. injection of pyrilamine (300 mg/horse) O-DMP was recovered at a level of about 20 ̄g/mL at 2 h postdose thereafter declining to about 2 ng/mL at 168 h postdose. After oral administration, the O-DMP recovery peaked at about 12 ̄g/mL at 8 h postdose and declined to <2 ng/mL at 168 h postdose. These results show that pyrilamine is poorly bioavailable orally (18%), and can be detected by sensitive enzyme-linked immunosorbent assay tests in urine for up to 1 week after a single administration. Care should be taken as the data suggest that the withdrawal time for pyrilamine after repeated oral administrations is likely to be at least 1 week or longer.

Spatial Ecology Of Raccoons Related To Cattle And Bovine Tuberculosis In Northeastern Michigan, Todd Atwood, Thomas Deliberto, Holly Smith, Justin Stevenson, Kurt C. Vercauteren Jan 2009

Spatial Ecology Of Raccoons Related To Cattle And Bovine Tuberculosis In Northeastern Michigan, Todd Atwood, Thomas Deliberto, Holly Smith, Justin Stevenson, Kurt C. Vercauteren

Michigan Bovine Tuberculosis Bibliography and Database

In 1995, Mycobacterium bovis, the causative bacterium of bovine tuberculosis (bTB), was detected in 5 beef cattle operations in Alcona County, Michigan, USA. In accordance with Federal law, the operations were depopulated to prevent the spread of bTB. Subsequent wildlife surveillance programs identified high prevalence of M. bovis in mesocarnivores, including raccoons ( Procyon lotor), which suggested that raccoons may be complicit in vectoring the pathogen among livestock operations. Our goal was to develop an empirical basis for generating hypotheses about the likelihood for raccoons to mediate the transmission of bTB to livestock. We found intersexual differences in …

Economic Impact Of Bovine Tuberculosis On Minnesota’S Cattle And Beef Sector, Brian Buhr, Kyle Mckeever, Kenji Adachi

Michigan Bovine Tuberculosis Bibliography and Database

In September 2005, the first case of bovine tuberculosis (BTB) in 34 years was discovered in Minnesota and led to a loss of Minnesota’s bovine TB free status. In October 2007 and January and February 2008, four additional cattle herds and deer infected with BTB were discovered in Roseau and Beltrami counties and Minnesota’s BTB status was changed from “modified accredited advanced” to “modified accredited” in April 2008. Each of these designations has increased regulatory requirements (and costs) for animal testing, record keeping, eradication practices, slaughtering and shipments of cattle within state and across state lines.

Michigan Bovine Tuberculosis Bibliography and Database

Surveillance and control activities related to bovine tuberculosis (TB) in free-ranging, Michigan white-tailed deer (Odocoileus virginianus) have been underway for over a decade, with significant progress. However, foci of higher TB prevalence on private lands and limited agency ability to eliminate them using broad control strategies have led to development and trial of new control strategies, such as live trapping, testing, and culling or release. Such strategies require a prompt, accurate live animal test, which has thus far been lacking.

Michigan Bovine Tuberculosis Bibliography and Database

Tuberculosis continues to be an important disease both in humans and animals. It causes morbidity, mortality, and economic loss worldwide. The occurrence of Mycobacterium bovis disease in humans, domesticated and wild animals confirms the relevance of this zoonosis. M. bovis in humans continues to be reported in industrialized countries and in immigrants from regions of the world where tuberculosis in cattle is endemic. The real incidence of M. bovis in humans in developing countries continues to be roughly underestimated due to the scarcity of appropriate laboratory facilities to isolate and to differentiate M. bovis strains. In Latin America, less than …

Biomechanical Evaluation Of A 6.5-Mm Headless, Tapered Variable Pitch Screw (Acutrak Plus) In Equine And Synthetic Bone, Andrew James Czak Lewis

LSU Master's Theses

Objectives – To compare compression pressure (CP) of 6.5mm Acutrak Plus (AP) and 4.5mm AO cortical screws (AO) when placed in simulated lateral condylar fractures of variable thickness in cadaveric equine third metacarpal (MC3) bones, and to compare pullout force and strength of AP and AO screws when placed in a synthetic bone substitute. Results – The AO screw configurations generated significantly greater compressive pressure compared to the AP configurations. The ratio of mean CP for AP screws to AO screws at 20, 12, and 8-mm, were 21.6%, 26.2%, and 34.2% respectively. For the pullout study, the AP constructs generated …

Turkish Journal of Veterinary & Animal Sciences

Experiments were conducted to compare the efficacy of montmorillonite (M) and montmorillonite nanocomposite (MN) to reduce the toxicity of aflatoxin (AF) in broiler chicks from 0 to 42 days of age. A total of 240 chicks were assigned to 6 dietary treatment groups (0 g of adsorbents and 0 mg of AF/kg feed, 3 g of M/kg feed, 3 g of MN/kg feed, 0.11 mg of AF/kg feed, 0.11 mg of AF plus 3 g of M/kg feed, and 0.11 mg of AF plus 3 g of MN/kg feed). Compared to the control, AF alone significantly decreased ADG and feed …
