In the present study, the anti-inflammatory action of lysophosphatidylethanolamine (lysoPtdEtn), orally administered, in zymosan A-induced peritonitis was examined. Oral administration of 2-DHA-lysoPtdEtn (ED(50), ~111 μg/kg) or 2-ARA-lysoPtdEtn (ED(50), 221 μg/kg) was found to inhibit the plasma
Recent studies suggest that CNS phospholipase A(2) (PLA(2) ) isoforms play a role in nociception, but until now, direct evidence of increased brain PLA(2) activity during allodynia or hyperalgesia is lacking. The present study was carried out, using lipidomics or systems wide analyses of lipids
The concentration of phospholipids and proteins was determined in 23 inflammatory synovial fluids obtained from human knee joints. The synovial fluid to plasma phospholipid ratio (0.48 and 0.37 at high and low inflammatory state) was lower than the value found for the total protein content (0.68 and
Vascular dementia is a transversal phenomenon in different kinds of neurodegenerative diseases involving acute and chronic brain alterations. Specifically, the role of phospholipids in the pathogenesis of dementia remains unknown. In the present study, we explored phospholipid profiles a month
Epidemiological studies have confirmed that PM2.5 could contribute to the development of atherosclerosis accompanied with lipids dysregulation. However, the lipids biomarkers involved in this progress remain largely unknown. In this study, a targeted lipidomic approach was used to find
Heightened threats for nuclear terrorism using improvised nuclear devices (IND) necessitate the development of biodosimetry assays that could rapidly assess thousands of individuals. However, the radiation exposures from an IND may be complex due to mixed fields of neutrons and photons (γ-rays),
Platelet-activating factor (PAF) is a potent lipid mediator that is implicated in numerous inflammatory diseases. C-reactive protein (CRP) is an acute-phase plasma protein that increases rapidly and dramatically in response to inflammation. In this study, we investigated the effect of the
The objectives of the present study were to (1) examine the effects of the phenotypic factors age, gender and BMI on the lipidomic profile and (2) investigate the relationship between the lipidome, inflammatory markers and insulin resistance. Specific ceramide, phosphatidylcholine and
OBJECTIVE
To determine whether circulating metabolic intermediates are associated with inflammation, oxidative stress and arterial stiffness in men with newly diagnosed type 2 diabetes and investigate the circulating metabolic intermediates that may predict the risk of developing
Sterile peritoneal exudates produced in rabbits injected with 1% glycogen contain a phospholipase A activity in a cell-free supernatant fraction that hydrolyzed a synthetic phospholipid (1,2-diacyl-sn-glycero-3-phospho-ethanolamine) and phospholipids of autoclaved Escherichia coli. This
Inflammatory liver diseases are associated with oxidative stress mediated particularly by neutrophilic granulocytes. At inflammatory loci, hypochlorous acid (HOCl) is generated by myeloperoxidase. HOCl reacts with a large variety of molecules and induces (among other reactions) the formation of
We have studied the molecular structure of platelet-activating factor" (P.A.F.), a mediator of inflammation obtained from blood leukocytes, macrophages, and platelets themselves. We have semi-synthetized a substance that possesses all the known physicochemical and biological characteristics of
Sporadic Alzheimer's disease (SAD) is the most common form of dementia, and cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most frequent hereditary ischemic small vessel disease of the brain. Relevant biomarkers or specific metabolic
Inhalation from ambient air and cigarette smoke is a common route of human exposure to polycyclic aromatic hydrocarbons (PAHs). Little information is available regarding hepatotoxicities of inhaled PAHs so for. In this study, we evaluated the toxic effects of intratracheally instilled benzo[a]pyrene
Inflammation has been suggested to play early and perhaps causative roles in Alzheimer's disease (AD) pathogenesis possibly in part by the overactivation of the aspartic acid protease named β-site amyloid precursor protein (APP) cleaving enzyme 1 (BACE1), which is responsible for the β-amyloid
