The fatty acid composition of Morris Hepatoma 7777 cells was modified by exposure to culture media that were supplemented with 0.1 to 0.36 mM oleic or linoleic acid for 5 days. Changes occurred in the fatty acid composition of both the cellular phospholipid and the neutral lipid fractions. Exposure to linoleic acid caused a large increase in the polyunsaturated fatty acid content of the cell li...

Introduction: Free radicals cause several human diseases. Antioxidants decrease the risk of cardiovascular diseases and heart attack, and prevent the development of cancers through neutralization of free radicals. This study set out to determine the antioxidative properties of Citrullus colocynthis growing in Khuzestan. This plant is traditionally used for the treatment of type II diabetes. ...

The oxidation processes of linoleic acid in the presence of ferulic acid, and 1-pentyl, 1-hexyl and 1-heptyl ferulates were observed at various temperatures and different molar ratios of each additive to linoleic acid. The processes were analyzed based on a kinetic equation of the autocatalytic type to evaluate the oxidative rate constant, k, and the kinetic parameter, Y(0), by which the initia...

A colorimetic assay for lipoxygenase activity has been developed. The assay is based on the detection of the lipoxygenase reaction product, linoleic acid hydroperoxide, by the oxidative coupling of 3-methyl-2-benzothiazolinone (MBTH) with 3-(dimethylamino)benzoic acid (DMAB) in a hemoglobin-catalyzed reaction. This test reaction is rapid and sensitive, and it offers advantages over other method...

The best health and nutrition results can be achieved not only from the consumption of fruits and vegetables with high antioxidant capacities, but also from medicinal plants and herbs. Therefore, in the present investigation, the bioactive compounds (polyphenols and flavonoids) and the radical scavenging capacities of Prolipid, a mixture of herbs, were studied. Water extracts showed relatively ...

Background: Considering the wide consumption of some synthetic antioxidants and their probable negative health effects, in this study, the protective effects of Satureja hortensis L. extracts in stabilizing soybean oil against oxidation at different concentrations (200 and 400 ppm) were tested. Methods: The aerial parts of S. hortensis L. were collected from Isfahan province and extracted with...

objective: menopause is the condition when regular menstrual periods cease and may be accompanied by psychological and physical symptoms. the purpose of current study was to determine nigella sativa effects on reproductive system in experimental menopause animal models. materials and methods: a series of experiments wasconducted to investigate the effects of different dosages of n. sativa (firs...

Background: Feeding unsaturated fatty acids sources in dairy cows is considered as a strategy to improve animal health during postpartum period and milk fatty acid profile. OBJECTIVES: This study aimed to investigate the effects of conjugated linoleic acid supplement and combination of sesame meal and oil on performance and milk fatty acid composition of dairy cows during transition period. MET...

Maize shows wide differences in linoleic acid due both to total lipid content and to fatty acid profile. Therefore, diets containing the same high maize percentage (up to 55%) can differ in linoleic acid content and lead to subcutaneous fats of differing suitability for raw ham curing. Two trials were performed on heavy pigs; in the first, 60 pigs (body weight 48.7+/-5.1 kg) were fed three diet...

The present study evaluated thephenolics composition and biological activities of various extracts Cyclamen coum. antioxidant properties these plant wasdetermined using the scavengingmethods (DPPH andABTS), total test systems (β-carotene/linoleic acid), reducing power (FRAP) assays.The antibacterial effect was examined with MIC method. phenolics were identified HPLC brine shrimp lethality used ...
