heavy metal accumulation in plants causes induction of oxidative stress. plants have severaldefense systems involved in detoxifying free radicals. in the present research we treated the 15 d.seedlings of b. napus grown in pots with different concentrations of cadmium (0, 10, 50 and 100 μm) ascdcl2. after 3 weeks we measured malondealdehyde (mda) content in leaves of treated plants as anindicati...

  Background: The dried fruits of Silybum marianum (L.) Gaertn (Compositae) contain silymarin, an isomeric mixture of flavonolignans. Silymarin acts as a strong anti -hepatotoxic. This fruits contains a high amount of oil .  Objective: The objective of this study was to determine total lipid content, fatty acid composition and content of different kind of tocopherols in seed oils of S. marianum...

background: this study examined the effect of grape seed proanthocyanidin extract (gspe) on lipid peroxidation content and activity of tissue antioxidant enzymes, including catalase, superoxide dismutase and glutathione peroxidase in diabetic rats. methods: thirty male rats were divided into three groups of 10 rats each: control, diabetic and diabetic groups that received 500 mg/kg gspe for 6 w...

The lipid composition of cells of Pseudomonas aeruginosa strains resistant to polymyxin was compared with the lipid composition of cells of polymyxin-sensitive strains as to their content of readily extractable lipids (RELs), acid-extractable lipids, the fatty acid composition of RELs, and the contents of various phospholipids in the REL fraction. The polymyxin-resistant strains had an increase...

In the current study the possible relationship between the Ca(2+)/Mg(2+) ratio of human syncytiotrophoblast plasma membranes and their lipid peroxidation and Ca(2+)-ATPase activity was determined. Syncytiotrophoblast plasma membranes of placental explants cultured under hypoxia increased their lipid peroxidation and Ca(2+) content, diminished their Ca(2+)-ATPase activity, and kept their Mg(2+) ...

The effects of dietary lipid and carbohydrate, and their interaction, on growth performance and body composition of juvenileblunt snout bream Megalobrama amblycephala were investigated. Fish were fed one of eight isonitrogenous (32% crude protein) diets containing 4% or 7% lipids and 25%, 30%, 35%, or 40% carbohydrate for nine weeks. Weight gain, feed conversion ratio, protein efficiency ratio,...

resistance of the weanling rat to acetaminophen (ap ap)-induced hepatotoxicity is manifested with regard to a surge in apap-glutathione (osh) conjugate formation in the liver [allameh et al. mech aging dev 95(1997)71]. the present study was conducted to assess the role of this detoxification pathway in apapinduced lipid per6xidationin the liver. lipid peroxidation measured as thiobarbituric aci...

Problem statement: In today’s scenario, microalgae are widely recognized as a promising source for biofuel production as a renewable source of energy. They are exceedingly rich in oil, which can be converted to biofuel. This paper deals with one of the method to enhance the lipid content in microalgae. Approach: Microalga, Chlorella pyrenoidosa, was grown autotrophically in batch culture and th...

Hepatic steatosis frequently complicates total parenteral nutrition (TPN). Some of the mechanisms responsible were examined in rats receiving calories as dextrose (CHO-TPN) or dextrose plus lipid emulsion (Lipid-TPN). Hepatic triglyceride content increased approximately threefold after CHO-TPN and twofold after Lipid-TPN (P less than 0.02). Hepatic triglyceride fatty acid composition reflected ...
