Activated polymorphonuclear leukocytes generate a cascade of reduced oxygen metabolites. In addition to their antimicrobial role, hydrogen peroxide (H2O2) and hypochlorous acid (HOCl) function as inflammatory mediators increase the protein permeability vascular endothelium. The objectives present study were compare effects H2O2 HOCl with respect relative potencies time course magnitude changes in cell shape endothelial monolayers derived from bovine pulmonary artery, determine if produced by...

Summary A retrospective study of 69 bronchoalveolar lavages (BAL) on horses was done to investigate the relationship between cell types and clinical signs in with small airway disease. Horses were grouped according findings. The groups as follows: I. cough only (n = 14), II. mucopurulent secretions trachea III. cough, abnormal lung sounds 24) IV., all above plus dyspnea at rest 17). An asymptomatic group formed from same population serve control 8). There a significant difference cytological...

Abstract The aim of the study was to analyze impact melatonin on brain oxidative stress in experimental biliary obstruction. Cholestasis done by a double ligature and section extrahepatic duct. Melatonin injected intraperitoneally (500 μg/kg/day). Malondialdehyde (MDA), reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), peroxidase (GPx) contents were determined tissue. Biliary obstruction raised MDA GSH cortex, cerebellum, hypothalamus areas. Moreover, scavenger enzyme...

Hepatic lipidosis and ketosis are frequent metabolic disorders in dairy cows during the transition period. The 2-methyl-2-phenoxy propionic acid (MFPA) is an activator of energy metabolism. objective this study was to evaluate effect administration MFPA 10 days prepartum day 36 postpartum on serum lipid profile, ovarian reactivity, milk yield. Fifty seven multiparous Holstein were divided into four groups. groups 1 (n = 14) 2 had body condition score (BCS) above 4; BCS 3 15) 4 between 3.25...

In a previous study, we demonstrated the therapeutic efficacy of subcutaneous injection GK1 peptide in melanoma mouse model, effectively increasing mean survival time by 42.58%, delaying tumor growth, and intratumoral necrosis compared with control. As first approach to investigate anti-melanoma effect GK1, this study was carried out determine hematological effects along both serum lung cytokine profiles metastatic model.Thirteen C57BL6 female mice were transfected lateral tail vein 2×10(5)...

Abstract The Southwestern U.S. has experienced frequent drought over the past 30 yr, and wildfire frequency intensity been increasing which threatens western rangelands. In west, livestock grazing systems often involve a combination of private, state, federal land, managers must comply with designated plans. 2022, Black Fire in southern NM was second largest state history burned hundreds thousands hectares rangeland including fencing impeded ability to management Local extension agents along...

Abstract Bovine respiratory disease (BRD) is the most significant health problem associated with newly received cattle in beef industry. Serum concentrations of extracellular histones increase a variety diseases and are known to be cytotoxic mammalian cells. Work our lab indicated that failure protect against effects may component severe cases cattle. The mechanisms or proteins neutralize not fully elucidated, but C-reactive protein complement activity have been reduced effect histones....

Abstract Distinguishing pregnant from non-pregnant ewes in early pregnancy allows for more efficient flock management by producers. While detection techniques like ultrasonography and hormone quantification are well established, these often not adaptable to field conditions or require specialized equipment training. The objective of this study was evaluate a validated bovine commercial on-farm test on efficacy detecting distinct blood constituents ewes. Rambouillet [n = 30; average body...

Abstract Infectious disease caused by exposure to Gram-negative bacterial endotoxin lipopolysaccharide (LPS) is recognized suppress female fertility. However, the effect of varying low dose during distinct stages follicle development on immune response, reproductive performance and lamb has yet be elucidated. Therefore, objective this study was evaluate acute phase mRNA abundance inflammatory markers, growth characteristics ewes challenged with subclinical doses LPS. Rambouillet (n = 36;...

Non-Hodgkin’s lymphomas are common canine cancers with variable demographic and clinical presentations. Their pathological characterization treatment lag far behind those of humans. We describe consecutive lymphoma patients detected over a one-year period at the National Autonomous University Mexico (UNAM). Of 4,512 dogs: 220 (4.9%) had cancer diagnosis, which 27 (0.6%) (12% patients). found an association Miniature Schnauzers, represented 18.5% (5/27) patients, but it was only 6.4%...

The aim of this study was to determine the values and changes in conventional optimised clotting tests, as well selected biochemical analytes during hepatic lipidosis postpartum dairy cows. Ten healthy ten Holstein cows with were based upon clinical history, examination, liver biopsy, flotation test histological analysis tissue. Prothrombin time (PT) partial thromboplastin (PTT) determined non-diluted diluted blood plasma samples. Clotting times samples prolonged there a difference PT value...

Hepatic lipidosis is a metabolic disorder that occurs frequently in dairy cattle. Its clinical evaluation on farms complex, as it based physi­cal, chemical and biological tests. The present study evaluates the practical use of hepatic cytology cattle suggests overall health production rates animals are not compromised with this procedure. Cell blood samples were obtained from 25 randomly selected multipa­rous Holstein cows at three different times during transition period (at calving 10 21...

Abstract Acute inflammation induced by chronic infection or a single intravenous administration of the bacterial endotoxin, lipopolysaccharide (LPS) induces immune responses capable depressing female fertility. However, effect dose and repeated endotoxin exposure during estrous cycle on response reproductive performance has yet to be investigated. To investigate effects varying doses LPS delivered at distinct stages follicular maturation, thirty-six Ramboulliet ewes (68.2 ± 1.1 kg; age 3 7...
