Sodium arsenate induce changes in fatty acids profiles and oxidative damage in kidney of rats.

Six groups of rats (n = 10 per group) were exposed to 1 and 10 mg/l of sodium arsenate for 45 and 90 days. Kidneys from treated groups exposed to arsenic showed higher levels of trans isomers of oleic and linoleic acids as trans C181n-9, trans C18:1n-11, and trans C18:2n-6 isomers. However, a significant decrease in eicosenoic (C20:1n-9) and arachidonic (C20:4n-6) acids were observed in treated rats.

Effects of sodium arsenate exposure on liver fatty acid profiles and oxidative stress in rats.

The present study aimed to evaluate the effect of arsenic on liver fatty acids (FA) composition, hepatotoxicity and oxidative status markers in rats. Male rats were randomly devised to six groups (n=10 per group) and exposed to sodium arsenate at a dose of 1 and 10 mg/l for 45 and 90 days. Arsenate exposure is associated with significant changes in the FA composition in liver.

Profiles of volatile compounds from nine new hybrids obtained by controlled crossings on olive Chemlali cultivar and Mediterranean varieties.

Virgin olive oil is a unique oil that can be consumed directly without any refining process. This particularity is due to the exceptional quality and flavour formed by the presence of more than 100 volatile compounds. Nine new hybrids obtained by controlled crossing of the Chemlali and seven ancient Mediterranean varieties cultivated in the same orchard under identical agronomic and pedoclimatic conditions were characterised by their main volatile compounds quantified by dynamic headspace-gas chromatography-MS.
