Oxidants and Antioxidants in Medical Science, 2012
This study aimed to elucidate whether inhalation of particulate matter 10 (PM10) coal dust change oxidative stress and peroxidative index in rats. A total of 42 Wistar male rats were randomly divided into seven groups including one control group, three groups exposed to coal dust for 14 days, and three groups exposed to coal dust for 28 days. The three

REFRACTIVE INDEX OF HYDROGEN PEROXIDE SOLUTIONS. A REVISION
Canadian Journal of Research, 1949Values for the refractive index of aqueous solutions of hydrogen peroxide reported some years ago by the senior author have been found in error by more than the estimated accuracy of measurements. The error is proportional to the concentration of the solutions and amounts to about 5 × 10−4 for the pure peroxide.

Red wine effects on peroxidation indexes of rat plasma and erythrocytes
International Journal of Food Sciences and Nutrition, 1996Moderate wine intake has been associated with low risk for cardiovascular disease, possibly due to its polyphenol content. We investigated the influence of these compounds on peroxidative indices of blood. Forty Sprague-Dawley rats were divided into four groups given the same AIN-76 diet but different types of isocaloric beverage: red wine, alcohol and

Some deuterium peroxide containing less than 0.3% ordinary hydrogen was produced both by the persulphate and the electric discharge methods. By means of fractional distillation, solutions of deuterium peroxide in deuterium oxide of various concentrations up to 90% were obtained, of which the following properties were measured: refractive index at 25°C,

In vivo breath alkane as an index of lipid peroxidation
Free Radical Biology and Medicine, 1991Interaction of active oxygen species with polyunsaturated fatty acids (PUFA) results in a series of reactions called lipid peroxidation. During the process of peroxidation of polyunsaturated fatty acids there is a scission of an alkane fragment extending from the methyl end of the fatty acid to the double bond.

Excretion of F2-isoprostanes in bile: A novel index of hepatic lipid peroxidation
Hepatology, 1995Lipid peroxidation is believed to be an important mechanism of liver injury caused by some xenobiotics. However, it has been difficult to demonstrate and quantify this process in vivo. Moreover, little is known about the disposition of lipids oxidized in the liver.

Body mass index changes and lipid peroxidation in adults with Down's syndrome
International Medical Review on Down Syndrome, 2012Introduction and objective Trisomy 21 or Down's syndrome (DS) is the most common cause of mental retardation of chromosomal origin, in which obesity is a public health problem. Obesity is a pro-oxidant state associated with lipid peroxidation and alterations of antioxidant mechanisms. The effect of gene dosage has been linked to oxidative stress in DS.

An accelerated stability test using the peroxide value as an index
Oil & Soap, 1933A quick stability test for lard is described which depends on the peroxide content for identification of the rancid point. By its use ordinary samples of lard can be evaluated for stability in a working day. Oleo oil also is being tested by this method. It is applicable to edible fats and oils and hydrogenated shortenings.

Hydrogen peroxide metabolism as an index of water stress tolerance in jute
Physiologia Plantarum, 1985Two species of jute plants Corchorus capsularis L. (cv. JRC 212) and C. olitorius L. (cv. JRO 632) were subjected to water stress for 2 and 4 days by withholding water. The relative water content (RWC) decreased in both plants under water stress but to a greater extent in C. olitorius. The C. olitorius seedlings also showed greater membrane injury than
