Breath alkanes as an index of lipid peroxidation.
Formation of free radicals and lipid peroxidation are mechanisms that are involved in many conditions including cellular damage. In a human body, there are many antioxidant systems likely to limit the production of free radicals and to reduce their deleterious effect. The peroxidation of polyunsaturated fatty acids, such as linoleic acid and linolenic acid which are cell membrane components, in...
متن کاملLipid Peroxidation: an Overview
Lipid peroxidation (LPO) in cellular membranes is associated with changes in physicochemical properties and impairment of protein functions located in membrane environment. Recent studies shows involvement of LPO in biological signaling and various diseases. Lipids are oxidized by three distinct mechanisms: enzymatic oxidation; non-enzymatic, free radical-mediated oxidation and non-enzymatic, n...
متن کاملAlcohol-induced generation of lipid peroxidation products in humans.
To address the hypothesis that elevated blood alcohol increases systemic oxidant stress, we measured urinary excretion of isoprostanes (iPs), free radical-catalyzed products of arachidonic acid. Ten healthy volunteers received acute doses of alcohol (Everclear-R) or placebo under randomized, controlled, double-blind conditions. Urinary iPF2a-III increased in a time- and dosage-dependent manner ...
متن کاملIncreased ethane exhalation, an in vivo index of lipid peroxidation, in alcohol-abusers.
Ethane exhalation was measured in 42 control subjects, 52 patients with various non-alcoholic liver diseases, and 89 alcohol abusers who had been admitted to hospital for alcohol withdrawal and assessment of liver disease (six with normal liver tests, 10 with steatosis with or without fibrosis, six with alcoholic hepatitis, 29 with cirrhosis, 34 with both cirrhosis and alcoholic hepatitis, and ...
متن کاملLipid Spectrum of Membranes and Lipid Peroxidation and Proteins in the Liver Echinococcosis in Humans
The pressure of hydatid cysts on liver tissue causes ischemia leading to disruption of metabolic processes in it. For this reason studies on revealing and improving dysfunctions in the mechanisms of oxygendependent processes allow to explain and adjust the characteristics of toxic liver damage in general [2]. Addressing these issues is closely related to fundamental research in general biologic...
