Changes in the salivary proteome 12 horses with two diseases included equine gastric ulcer syndrome (EGUS), glandular disease (EGGD) (n = 6) and squamous (ESGD) 6), were evaluated using a high-resolution LC-MS/MS analysis of TMT-labelled peptides compared to 10 healthy control horses. Serum was also analysed for comparative purposes. The comparison between EGGD controls showed significant changes proteins, whereas 36 proteins differently abundant ESGD groups. most upregulated case related...

Equine gastric ulcer syndrome (EGUS) is a highly prevalent disease that affects horses worldwide. Within EGUS, two different forms have been described: equine squamous (ESGD) and glandular (EGGD). The associated clinical signs cause detrimental activity performance, reducing the quality of life animals. Saliva can contain biomarkers for EGUS could be potentially used as complementary tool diagnosis. objective this work was to evaluate measurements calprotectin (CALP) aldolase in saliva...

Non-alcoholic steatohepatitis (NASH) is part of the spectrum non-alcoholic fatty liver disease (NAFLD), currently most common cause abnormal tests. Given difficulty studying all factors involved in it human populations, studies animal models might provide crucial insights pathogenesis steatohepatitis. Several physiological features predispose birds to fat deposition liver. The present study was conceived explore possibilities chicken fed a cholesterol and enriched diet as model for We used...

Changes in the oxidative status of blood horses suffering from gastric ulcers and colic intestinal aetiology (CIE) have been reported. However, saliva can also be a source biomarkers status. Therefore, this study aims to validate automated assays for measurement (ferric reducing ability saliva/serum-FRAS/FRAP, cupric antioxidant capacity-CUPRAC, Trolox equivalent capacity-TEAC, uric acid, advanced oxidation protein products-AOPP) serum horses, assess their changes different ulcer diseases...

Equine gastric ulcer syndrome (EGUS) is currently one of the more frequent diseases in horses. We aimed to identify changes salivary proteome horses with EGUS at diagnosis and after successful treatment by using gel proteomics. Saliva samples were collected from nine before matched healthy controls. SDS-PAGE (1DE) two-dimensional electrophoresis (2DE) performed, significantly different protein bands spots identified mass spectrometry. Horses had increases proteins such as adenosine deaminase...

The mean duration and amplitudes of the lead II electrocardiogram were determined in peregrine falcon (Falco peregrinus brookei) using 10 birds ranging age from 1 to 5 yr. Electrocardiograms performed on unanesthetized falcons order avoid anesthesia effect electrocardiogram, by a method which seems induce tonic immobility–like reaction. All had normal sinus rhythm, with heart rate 268 beats per minute. Mean durations PR, ST, QT, RR intervals higher (but not statistically significant) females...

Abstract Objective —To study the pharmacokinetics of difloxacin (5 mg/kg) following IV, IM, and intragastric (IG) administration to healthy horses. Animals —6 mature Procedures —A crossover design with 3 phases was used (15-day washout periods between treatments). An injectable formulation (5%) administered IV IM in single doses mg/kg); for IG administration, an oral solution prepared via nasogastric tube. Blood samples were collected before at intervals after each administration. A...

The duration of electrocardiograph wave forms and intervals were determined in 179 Spanish-bred (Andalusian) horses aged from 1 month to 17 years. values compared with those other breeds, the relationship between electrocardiographic data age was examined. High correlation coefficients found PR, ST QT horses, an inverted relation heart rate found. A multiple range analysis made results suggest that significant changes occurred at 6 months second year life.

High levels of circulating lipids contribute to both the development non-alcoholic liver steatosis (NALS) and peripheral arterial disease, leading increased thrombotic risk. However, effects hyperlipidemia on hepatic proteins have barely been studied. Antithrombin is a serpin with anticoagulant anti-inflammatory roles. The conformational flexibility antithrombin renders it susceptible both, genetic posttranslational modifications. Thus, mutations environmental factors shown alter this...
