Biomarkers Of Inflammation, Metabolism, And Oxidative Stress In Blood, Liver, And Milk Reveal A Better Immunometabolic Status In Peripartal Cows Supplemented With Smartamine M Or Metasmart, J. S. Osorio, E. Trevisi, P. Ji, J. K. Drackley, D. Luchini, G. Bertoni, J. J. Loor
Biomarkers Of Inflammation, Metabolism, And Oxidative Stress In Blood, Liver, And Milk Reveal A Better Immunometabolic Status In Peripartal Cows Supplemented With Smartamine M Or Metasmart, J. S. Osorio, E. Trevisi, P. Ji, J. K. Drackley, D. Luchini, G. Bertoni, J. J. Loor

The peripartal dairy cow experiences a state of reduced liver function coupled with increased inflammation and oxidative stress. This study evaluated the effect of supplementing basal diets with rumen-protected Met in the form of MetaSmart (MS) or Smartamine M (SM) (both from Adisseo Inc., Antony, France) during the peripartal period on blood and hepatic biomarkers of liver function, inflammation, and oxidative stress. Thirty-seven multiparous Holstein cows were fed the same basal diet from −50 to −21 d relative to expected calving [1.24 Mcal/kg of dry matter (DM); no Met supplementation]. From −21 d to calving, the cows received diets …
Generation And Use Of Monoclonal Antibodies To Ldentify Subpopulations Of Post Thaw Stallion Sperm, Sarah Abdulaziz Almuhanna
Generation And Use Of Monoclonal Antibodies To Ldentify Subpopulations Of Post Thaw Stallion Sperm, Sarah Abdulaziz Almuhanna
Masters Theses
Artificial insemination (AI) is commonly used for breeding of horses. Selecting high quality semen is critical to AI success but is difficult to achieve. In this study, we investigate the potential of generating antibodies against stallion sperm to identify subpopulations of post-thaw sperm based on surface markers. Female Balb/C mice are immunized with semen from a 24-year-old fertile stallion followed by booster immunizations each week for at least six weeks. Monoclonal antibodies are generated by fusion of myeloma cells to mouse spleen cells. Eight monoclonal antibodies resulting from these fusions are subdivided into four immunostaining patterns. These patterns differentially recognize …
Clinical Investigation Of Plethysmographic Variability Index: A Derivative Index Of Pulse Oximetry In Anesthetized Dogs, Vaidehi V. Paranjape
Clinical Investigation Of Plethysmographic Variability Index: A Derivative Index Of Pulse Oximetry In Anesthetized Dogs, Vaidehi V. Paranjape
Open Access Theses
Plethysmographic Variability Index (PVI) is a derivative index of pulse oximetry that allows evaluating an individual's intravascular volume status. Perfusion Index (PI) represents the strength of pulse signal at the anatomic site of measurement from which PVI is calculated using changes in PI over respiratory cycles. Plethysmographic Variability Index has been used to detect hypovolemia and predict fluid responsiveness in mechanically ventilated human patients however, fewer studies are available in spontaneously breathing patients. The use of PVI has not been explored extensively in dogs so far. The goals of this study were to establish a common range for PVI and …

In the present study, our aim was to compare physiological and behavioural responses to different noxious stimuli to those of a standardized innocuous stimulus, to possibly identify aversive responses indicative of injury detection in a commercially important marine teleost fish, the Atlantic cod. Individual fish were administered with a noxious stimulus to the lip under short-term general anaesthesia (MS-222). The noxious treatments included injection of 0.1% or 2% acetic acid, 0.005% or 0.1% capsaicin, or piercing the lip with a commercial fishing hook. Counts of opercular beat rate (OBR) at 10, 30, 60, 90 and 120 min and observations of …

Effect Of Confinement On Water-Borne And Whole Body Cortisol In Wild And Captive-Eared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Culum Brown, Sinan Ali
Effect Of Confinement On Water-Borne And Whole Body Cortisol In Wild And Captive-Eared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Culum Brown, Sinan Ali
Physiology Collection
Whole body and water-borne cortisol levels were measured in captive reared and wild Rainbowfish (Melanoteania duboulayi Castelnau 1878) subjected to social isolation by confining them in a beaker for 30 min to induce an acute stress response. Wild fish had higher levels of cortisol before and after exposure to a mild stressor and also showed the greatest stress response. The differences in stress responses are likely the result of artificial selection in the captive environment. Importantly, there was a strong linear relationship between whole body and water-borne cortisol in wild and captive reared populations (r2 =0. 95 and 0.84, …
Stress And Reproductive Hormones Reflect Inter-Specific Social And Nutritional Conditions Mediated By Resource Availability In A Bear–Salmon System, Heather M. Bryan, Chris T. Darimont, Paul C. Paquet, Katherine E. Wynne-Edwards, Judit E. G. Smits

Food availability can influence the nutritional and social dynamics within and among species. Our investigation focused on grizzly and black bears in coastal British Columbia, Canada, where recent and dramatic declines in their primary prey (salmon) raise concerns about potentially negative effects on bear physiology. We examined how salmon availability relates to stress and reproductive hormones in coastal grizzly (n = 69) and black bears (n = 68) using cortisol and testosterone. In hair samples from genotyped individuals, we quantified salmon consumption using stable isotope analysis and hormone levels by enzyme immunoassay. To estimate the salmon biomass available to each …
