The elaboration of solid and non- intrusive strategies for the assessment of oxidative worry in human body is a standout amongst the most critical strides towards perceiving the assortment of oxidative disorders apparently created by Reactive Oxygen Species (ROS). Lipid peroxidation is a standout amongst the most well-known components related with oxidative anxiety, and the estimation of lipid peroxidation items has been utilized to assess oxidative worry in vivo conditions. The estimation of conjugated dienes and lipid hydro peroxide, while the evaluation of optional final results incorporates thiobarbituric acid reactive substances, vaporous alkanes and prostaglandin F2-like items, named F2-isoprostanes (F2-iPs). As of late, F2-iPs have been viewed as the most significant, precise and solid marker of oxidative worry in vivo and their evaluation is suggested for surveying oxidant wounds in people. The motivation behind this paper is to give some data on organic chemistry of isoprostanes and their use as a marker of oxidative anxiety. Keywords: Lipid peroxidation; Prostaglandin F2; Conjugated undifferentiated from prostaglandins PGF2 to recognize upgraded rates products; Arachidonic acid metabolites of lipid peroxidation.

In particular, cardiac fibrosis is considered as a major factor causing myocardial infarction and heart failure. In particular, oxidative stress is a major cause of heart fibrosis. In order to control such oxidative stress, the importance of nuclear factor erythropoietin 2 related factor 2 (NRF2) has recently been highlighted. In this review, we will discuss the activation of NRF2 by docosahexanoic acid (DHA), eicosapentaenoic acid (EPA), and the specialized pro-resolving lipid mediators (SPMs) derived from polyunsaturated lipids, including DHA and EPA. Additionally, we will discuss their effects on cardiac fibrosis via NRF2 activation. Keywords: cardiac fibrosis; NRF2; lipoxins; resolvins; maresins; neuroprotectins 1. Introduction Cardiovascular disease is the leading cause of death worldwide [1]. Cardiac fibrosis is a major factor leading to the progression of myocardial infarction and heart failure [2]. Cardiac fibrosis is characterized by the net accumulation of extracellular matrix proteins in the cardiac stroma and ultimately impairs cardiac function [3]. Therefore, interest in substances with cardioprotective activity continues.

    Detection of F2-Isoprostanes and F4-Neuroprostanes in Clinical Studies

    Mini Review Detection of F2-isoprostanes and F4-neuroprostanes in Clinical Studies Hsiu-Chuan Yen Graduate Institute of Medical Biotechnology Department of Medical Biotechnology and Laboratory Science Chang Gung University, Taoyuan, Taiwan Detecting stable products of oxidative damage is the most reliable approach to access oxidative stress in vivo. F2-isoprostanes (F2-IsoPs) and F4-neuroprostanes (F4-NPs) are the most specific markers of lipid peroxidation, which is superior to other markers of oxidative damage for clinical studies in many ways. F2-IsoPs is formed from peroxidation of arachidonic acid that is abundant in all kind of cells, while F4-NPs is derived from docosahexaenoic acid enriched in neurons. Moreover, F2-IsoPs is known to exhibit biological activities, such as vasoconstriction and platelet aggregation. Gas chromatography/negative-ion chemical-ionization mass spectrometry (GC/NICI-MS) is the reference method and the method with highest sensitivity to quantify F2-IsoPs and F4-NPs. F2-IsoPs is not only a widely used gold marker of lipid peroxidation detectable in all types of body fluids, but also a cause of diseases due to its biological activities, a marker to evaluate severity or predict out- come of diseases, or a tool to monitor the effectiveness of antioxidant therapy. Clinical studies de- tecting F4-NPs are little because cerebrospinal fluid or brain tissues are needed, but it is more useful than F2-IsoPs in selectively evaluating neuronal oxidative damage.

Thorax 2003;58:505–509 Background: Cysteinyl leukotrienes (Cys-LTs) and isoprostanes are inflammatory metabolites derived from arachidonic acid whose levels are increased in the airways of asthmatic patients. Isoprostanes are relatively stable and specific for lipid peroxidation, which makes them potentially reliable biomarkers for oxidative stress. A study was undertaken to evaluate the effect of a course of oral steroids on Cys-LT and 8-isoprostane levels in exhaled breath condensate of children with an asthma exacerbation. Methods: Exhaled breath condensate was collected and fractional exhaled nitric oxide (FENO) and spirometric parameters were measured before and after a 5 day course of oral prednisone (1 mg/kg/ day) in 15 asthmatic children with an asthma exacerbation. Cys-LT and 8-isoprostane concentrations were measured using an enzyme immunoassay. FENO was measured using a chemiluminescence ana- lyser. Exhaled breath condensate was also collected from 10 healthy children.

    Huber 1 My Favorite Protein: Cyclooxygenase By: Kristen Huber CH 791A - Biomolecular Structures Craig Martin and Jeanne Hardy December 9, 2005 The goal of pain management has been sought after for many years, meaning people are constantly striving to improve function, enabling individuals to participate in day-to-day activities. One specific aspect of this field lies within the area inflammation. Various diseases such as rheumatic disease and arthritis cause a great deal of pain due to inflammation. For this reason, the mechanism of this disorder needed to be determined so anti-inflammatory drugs could be developed in order to aid individuals with such a disease. In the 1930’s, the prostaglandin was determined to be a major component in pain and inflammation, allowing the mode of action of pain management to begin to take shape. Prostaglandins were discovered to be mediators in inflammation that can be found in virtually all tissues and organs. “They are autocrine and paracrine lipid mediators which act upon platelet, endothelium, uterine and mast cells among others.” 1 After this became known, the mechanism for these inflammation mediators was determined in order to try to find a way to inhibit the cycle. In doing this a fascinating enzyme was discovered called cyclooxygenase (otherwise known as COX) which would aid in their journey to anti-inflammatory drug discovery due to the fact that this enzyme catalyzes this conversion of arachidonic acid to PGG2, an vital step in the prostaglandin cycle. Now prostaglandins are synthesized in the cell from arachidonic acid. This component is released from membrane phospholipids by phospholipase A2, which is activated by various stimuli.

Lord,1* Sheri Anderson,1 and David W. Stanley2 Many studies have documented the involvement of eicosanoids in insect cellular immune responses to bacteria. The use of the fungal pathogen Beauveria bassiana as a nodulation elicitor, with inhibition of phospholipase A2 by dexamethasone, extends the principle to fungi. This study also provides the first evidence of involvement of the lipoxygenase (LOX) pathway rather than the cyclooxygenase (COX) pathway in synthesis of the nodulation mediating eicosanoid(s). The LOX product, 5(S)- hydroperoxyeicosa-6E,8Z,11Z,14Z-tetraenoic acid (5-HPETE), substantially reversed nodulation inhibition caused by dexam- ethasone and the LOX inhibitors, caffeic acid and esculetin.

Recently, metabololipidomic-based studies using advanced mass spectrometry have measured the oxylipins generated during acute and chronic physical exercise and described the related physiological effects. The objective of this systematic review was to provide a panel of the primary exercise-related oxylipins and their respective functions in healthy individuals. Searches were performed in five databases (Cochrane, PubMed, Science Direct, Scopus and Web of Science) using combinations of the Medical Subject Headings (MeSH) terms: “Humans”, “Exercise”, “Physical Activity”, “Sports”, “Oxylipins”, and “Lipid Mediators”. An adapted scoring system created in a previous study from our group was used to rate the quality of the studies. Nine studies were included after examining 1749 documents. Seven studies focused on the acute effect of physical exercise while two studies determined the effects of exercise training on the oxylipin profile. Numerous oxylipins are mobilized during intensive and prolonged exercise, with most related to the inflammatory process, immune function, tissue repair, cardiovascular and renal functions, and oxidative stress.
