Circadian Behavioral Responses To Light And Optic Chiasm-Evoked Glutamatergic Epscs In The Suprachiasmatic Nucleus Of Iprgc Conditional Vglut2 Knock-Out Mice, Michael G. Moldavan, Patricia J. Sollars, Michael R. Lasarev, Charles N. Allen, Gary E. Pickard

School of Veterinary and Biomedical Sciences: Faculty Publications

Intrinsically photosensitive retinal ganglion cells (ipRGCs) innervate the hypothalamic suprachiasmatic nucleus (SCN), a circadian oscillator that functions as a biological clock. ipRGCs use vesicular glutamate transporter 2 (vGlut2) to package glutamate into synaptic vesicles and light-evoked resetting of the SCN circadian clock is widely attributed to ipRGC glutamatergic neurotransmission. Pituitary adenylate cyclase-activating polypeptide (PACAP) is also packaged into vesicles in ipRGCs and PACAP may be coreleased with glutamate in the SCN. vGlut2 has been conditionally deleted in ipRGCs in mice [conditional knock-outs (cKOs)] and their aberrant photoentrainment and residual attenuated light responses have been ascribed to ipRGC PACAP release. However, …

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine respiratory disease complex (BRDC) is one of the most significant diseases of cattle. Bacterial pathogens involved in BRDC include Mannheimia haemolytica, Mycoplasma bovis, Histophilus somni, and Pasteurella multocida. We developed and evaluated a multiplexed real-time hydrolysis probe (rtPCR) assay using block-based Peltier and rotary-based thermocycling on lung tissue, nasal swabs, and deep nasopharyngeal swabs. The rtPCR results were compared to culture or a gel-based M. bovis PCR using statistical analysis to determine optimum quantification cycle (Cq) cutoffs to maximize agreement. The limits of detection were 1.2–12 CFU/reaction for each pathogen. M. haemolytica was the most prevalent organism detected …

Coordinated Regulation Of Transcription By Ccpa And The Staphylococcus Aureus Twocomponent System Hptrs, Joseph M. Reed, Sean Olson, Danielle F. Brees, Caitlin E. Griffin, Ryan A. Grove, Paul J. Davis, Stephen D. Kachman, Jiri Adamec, Greg A. Somerville

School of Veterinary and Biomedical Sciences: Faculty Publications

The success of Staphylococcus aureus as a pathogen is due in part to its ability to adapt to changing environmental conditions using signal transduction pathways, such as metaboliteresponsive regulators and two-component systems. S. aureus has a two-component system encoded by the gene pair sav0224 (hptS) and sav0223 (hptR) that regulate the hexose phosphate transport (uhpT) system in response to extracellular glucose-6-phosphate. Glycolytic intermediates such as glucose-6-phosphate are important carbon sources that also modulate the activity of the global metabolite-responsive transcriptional regulator CcpA. Because uhpT has a putative CcpA binding site in its promoter and …

The goals of this study were to identify SNPs from a collection of geographically diverse and epidemiologically unlinked M. bovoculi strains from the eyes of IBK positive cattle (n = 183) and another from the eyes …

Differential Modulation Of Human Gabac‑Ρ1 Receptor By Sulfur‑Containing Compounds Structurally Related To Taurine, Lenin David Ochoa‑De La Paz, Martin González‑Andrade, Herminia Pasantes‑Morales, Rodrigo Franco, Rubén Zamora‑Alvarado, Edgar Zenteno, Hugo Quiroz‑Mercado, Roberto Gonzales‑Salinas, Rosario Gulias‑Cañizo

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: The amino acid taurine (2-Aminoethanesulfonic acid) modulates inhibitory neurotransmitter receptors. This study aimed to determine if the dual action of taurine on GABAC- ρ1R relates to its structure. To address this, we tested the ability of the structurally related compounds homotaurine, hypotaurine, and isethionic acid to modulate GABAC- ρ1R.

Results: In Xenopus laevis oocytes, hypotaurine and homotaurine partially activate heterologously expressed GABAC- ρ1R, showing an increment in its deactivation time with no changes in channel permeability, whereas isethionic acid showed no effect. Competitive assays suggest that hypotaurine and homotaurine compete for the GABA-binding site. In addition, their effects were …

School of Veterinary and Biomedical Sciences: Faculty Publications

Sarcoplasmic/endoplasmic reticulum Ca²⁺ adenosine triphosphatase (SERCA)2a, a critical regulator of calcium homeostasis, is known to be decreased in heart failure. Patients with myocarditis or dilated cardiomyopathy develop autoantibodies to SERCA2a suggesting that they may have pathogenetic significance. In this report, we describe epitope mapping analysis of SERCA2a in A/J mice that leads us to make five observations: 1) SERCA2a contains multiple T cell epitopes that induce varying degrees of myocarditis. One epitope, SERCA2a 971–990, induces widespread atrial inflammation without affecting noncardiac tissues; the cardiac abnormalities could be noninvasively captured by echocardiography, electrocardiography, and magnetic resonance microscopy imaging. 2) SERCA2a …

To Live And Fly In La: Using Bird Strike And Management Program Information To Improve Safety At Airports In The Los Angeles Basin, Todd J. Pitlik, Elizabeth Hermann, Eric Peralta, Brian E. Washburn

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife-aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Wildlife strikes can be evaluated at different levels, include efforts to examine these problems at the national, regional, or state level, or for an individual airport. Similarly, wildlife strikes involving individual wildlife species or guilds can be examined at varying scales. Although wildlife strike analyses at the national, regional, or species/guild level are valuable, airport-specific analyses are essential for the effective implementation and evaluation of integrated wildlife damage management programs as these actions are conducted at the airport level. The species that present hazards to safe aircraft operations varies …

Isolation Of Multidrug Resistant Coliforms And Their Bacteriophages From Swine Slurry, Adrian Augustyniak, Bartlomiej Grygorcewicz, Pawe? Nawrotek

Turkish Journal of Veterinary & Animal Sciences

Slurry management is a contemporary agricultural problem. Although liquid manure is a valuable fertiliser, it may pose a microbiological threat due to spreading of bacteria resistant to various antibiotics. Fermentation has been proposed as a solution to this problem, although it does not fully eliminate the antibiotic-resistant strains. The presence of gram-negative rods resistant to antimicrobials may cause an uncontrolled transmission of resistance factors and genes in the natural environment. Therefore, a biocontrol system is necessary to prevent this phenomenon. The aim of this study was to detect multidrug-resistant (MDR) bacteria and their lytic bacteriophages in raw swine slurry. For …
