lithium is widely used in medicine as an anti-depressive drug. in spite of abundant literature, questions on the side effects of lithium ions are far from being answered. in this study, the effects of lithium on biochemical parameters related to lipid metabolism were investigated. male wistar rats were treated with different doses of lithium for a period of up to 60 days. blood samples were col...

background: the lipid peroxides and their degradation products are highly toxic to spermatozoa and may play a major role in sperm dysfunction. the purpose of this study was to determine the level of lipid peroxidation as indicated by malondialdehyde (mda) in the spermatozoa and seminal plasma of asthenozoospermic and normozoospermic males. in addition, correlation of lipid peroxidation with mot...

fenpropathrin is a new pyrethroid insecticide used to control crop pests. the aim of this study was to evidence fenpropathrin-induced oxidative stress and alterations in biochemical parameters in the freshwater fish, alburnus mossulensi s. total antioxidant capacity, malondialdehyde (mda), catalase activity (cat), aspartate aminotransferase (ast), alanine aminotransferase (alt), alkaline phosph...

microbial lipids have a great similarity to the lipids obtained from plants and animals. triacylglycerol is the storage lipid in most of eukaryotic cells; this characteristic attracts a lot of attention for using these lipid sources in biodiesel production. accumulation of neutral lipid composed of triacylglycerol and sterylster is an induced response to environmental stresses in many living or...

this study was carried out to evaluate the effects of different dietary protein (30, 35, 40%) and lipid levels (10, 12, 14%) on growth performance and physiological changes of juveniles caspian kutum (rutilus frisii kutum). six hundred and seventy five fish (1.15 ± 0.01 g) were distributed into 27 aquaria (45 l) and were fed four times daily for 8 weeks. interaction between protein and lipid di...
