Can isoprostanes be used to predict survival in horses with colic?
… year. The outcome is fatal in 11% of cases. F2-isoprostanes are the "gold standard" for assessment of oxidative stress in vivo and have been used extensively to quantify lipid peroxidation in association with risk factors in various diseases in humans. Because horses with colic may have …

Phytoprostane F1
Isoprostane F2 sind Autoxidationsprodukte der Arachidonsäure, die über radikal-katalysierte Oxidation entstehen. Bei einigen Erkrankungen im Tier konnte gezeigt werden, daß die Konzentration von Isoprostanen F2 mit dem verstärkten Vorkommen von freien Radikalen korreliert, weshalb Isoprostane heute …

F₂-isoprostanes study after exposure to selected nanoparticles by liquid chromatography/tandem mass spectrometry and investigation of nanoparticles on the cytotoxicity effect of arsenic in vitro
… in human lung epithelial cells (A549). F₂-isoprostanes are novel reliable biomarkers for lipid peroxidation. In the first part of this work, total free F₂-isoprostanes were quantified by high performance liquid chromatography/mass spectrometry followed by the exposure of SiO₂ (15 nm), CeO₂ …

Time-restricted eating on inflammation and oxidative stress in overweight, older adults
… C-reactive protein) and oxidative stress (8-isoprostane) in older adults with overweight. No significant differences were found in the outcomes of interest compared to baseline after four-week TRE (16:8) intervention. A short-term TRE intervention produced reductions in TNF-α [43.2 (11.2) …

Effect of acute dietary nitrate consumption on submaximal oxygen consumption and oxidative stress in hypoxia
… exercise, compared to rest, catalase and 8-isoprostane increased at 3500m in both the placebo and nitrate rich groups (p<0.05). There was no difference between groups (placebo vs nitrate rich) for either of these markers of oxidative stress. Our findings suggest that acute nitrate …

The Acute And Chronic Effects Of Resveratrol On Renal Function And Blood Pressure
… stress, as measured by urinary excretion of 8-isoprostane, in either model. Notable, short term exposure to fructose (2 weeks), independent of blood pressure or salt, increased oxidative stress. It is well-defined from our data that resveratrol has distinct physiological actions on nitric oxide …

Cardiovascular function in animal models of metabolic syndrome and type 2 diabetes : the role of inducible nitric oxide synthase (iNOS)
… blood pressure elevation and the increase of 8-isoprostane formation in the fructose-fed rats. We conclude that heart function is compromised and regional blood flow is altered in the ZDF rats. Activation of iNOS plays an important role in suppressing heart dysfunction but does not affect …

The effects of two modes of exercise training on plasma biomarkers of inflammation and oxidative stress in patients with symptomatic peripheral artery disease
… Analysis of plasma for TNF alpha, IL-10, and F2 Isoprostane were performed at baseline and following 12 weeks of moderate intensity, claudication inducing treadmill training (T), upper body ergometry training (UBE), or usual care (C). Analysis of covariance was used to evaluate changes among …

Nitrates and Left Ventricular Dysfunction
… measured by plasma malondialdehyde (MDA) and 8-isoprostane were not increased in patients with LV dysfunction treated with standard HF therapy. No positive correlations to the markers of severity of HF were found. Long-term IS-5-MN therapy did not influence P-MDA concentrations. Results from …

Role of Oxidative Stress in Behavioral, Cognitive and Biochemical Impairment in a Rat Model of Social Stress
… (systemic marker of stress), and plasma 8-isoprostane (marker of OS). Furthermore, GP treatment significantly increased SD-induced decrease in cellular pool of key antioxidant enzymes such as glyoxalase-1, glutathione reducatse-1 and superoxide dismutases in specific regions of the brain …

The effects of polyphenol rich chocolate on cardiovascular risk and glycaemic control in type 2 diabetes mellitus

Feeding peroxidized soybean oil to finishing pigs: Effects on performance, nutrient digestibility, carcass characteristics, and the shelf-life of loin chops and commercially manufactured bacon
… had the greatest (P < 0.01) concentrations of F2-Isoprostane in plasma and urine TBARS compared to the other SO treatments. Carcasses of 90°C pigs weighed 6.0, 8.6, and 6.9 kg less than (P < 0.03) 22.5°C, 45°C, and 180°C carcasses, respectively. Livers of 90°C and 180°C pigs were 14.3 and 11.7%, …

Biomarkers of oxidative stress and inflammation in biological samples collected from recurrent airway obstruction (RAO)-affected horses and their controls
