Copepods are among the most abundant and diverse groups of mesozooplankton in the world's oceans. Each species has a certain depth range within which different individuals (of the same life stage and sex) are found. Lipids are accumulated in many calanoid copepods for energy storage and reproduction. Lipid content in some species increases with depth, however studies so far focused mostly on te...

Wistar male rats were administrated Various Kinds of fats orally by a stomach tube, and each lipid content and fatty acid composition of each lipid fraction in the lung and liver were measured at time intervals of 3, 6 and 9 hours after administration. Both lung and liver showed increase of each lipid content, especially that of phospholipid content, 6 hours after the administration of safflowe...

Obesity is a main reason of type 2 diabetes and also chronic exposure to arsenic (As)can produce diabetic symptoms. In previous studies, the association between high-fat dietand arsenic in the incidence of diabetes was found, but the role of beta cells activity, livermitochondrial oxidative stress, and hepatic enzymes (leptin, adiponectin and beta amylase)was unclear. Thus, present study was co...

One mutant (HP-1) with higher growth rate was obtained from Nannochloropsis oceanica IMET1 by heavy-ion irradiation mutagenesis. Compared to the wild type, the biomass accumulation and maximum growth rate of HP-1 were individually increased by 19% and 6%, and its lipid productivity was increased by 28% from 211 to 271 mg L(-1) d(-1). Subsequently analysis indicated photosynthetic efficiency of ...

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...

We assessed changes in ultrastructure, membrane lipid peroxidation and antioxidant systems for cucumbner seedlings subjected to low temperature stress (day/night temperature of 8 oC /5 oC) that had been either pre-treated with 10% PEG for 2 days or not. We found extensive cell structure damage in the non-treated seedlings, whereas the seedlings pretreated with PEG to simulate drought remain...

The proximate composition and fatty acid (FA) profiles of five Brazilian freshwater fish species, namely Brycon cephalus (BC), Cichla ocellaris (CO), Prochilodus lineatus (PL), Leporinus friderici (LF) and Pseudoplatystoma corruscans (PCO), were investigated. CO and LF exhibited the highest (p < 0.05) moisture content, as well as one of the lowest (p < 0.05) lipid values, whereas BC presented t...

BACKGROUND We previously showed that the progression of atherosclerosis in the Reversa mouse (Ldlr(-/-Apob100/100Mttpfl/fl) Mx1Cre(+/+)) was arrested when the hyperlipidemia was normalized by inactivating the gene for microsomal triglyceride transfer protein. Here, we tested whether atherosclerosis would regress if the lipid levels were reduced after advanced plaques formed. METHODS AND RESUL...

Biologically derived fuels are viable alternatives to traditional fossil fuels, and microalgae are a particularly promising source, but improvements are required throughout the production process to increase productivity and reduce cost. Metabolic engineering to increase yields of biofuel-relevant lipids in these organisms without compromising growth is an important aspect of advancing economic...

Background: Medicinal plants with biologically active components such as antioxidant and antidiabetic are useful sources of novel therapeutics. In Iran, traditionally believed that the aqueous extract of berberry fruit (Berberis integerima F.) improved health, especially in people with diabetes. Objective: In this study, in vitro phytochemical and antioxidant activities of B. integerrima and...
