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...

The lipid content and composition of the reef-building coral Acropora downingi, the largest coral reef of Hengam Island, were examined throughout a year. The results showed that the lipid content of A. downingi significantly differs in different seasons (t-test, P< 0.05). Depending on the season and spawning times, the lipid content of A. downingi ranged from 16.5 to 37.7 % (dry weight). The to...

background: this study aimed at determining the appropriate method for dewatering and drying biomass and selecting a suitable organic solvent for lipid extraction. methods: nannochloropsis oculata was cultured in gillard f/2 medium and after reaching the end of the stationary growth phase, algal biomass was separated from aqueous by centrifuge and dried through three methods: oven, air-dried an...

abstract this experiment was carried out to determine the effects of proline and ascorbic acid on chilling injury, electrolyte leakage, lipid peroxidation, peroxide hydrogen and antioxidant enzymes activity of thompson grape (vitis vinifera l.) fruit. grape fruits were treated by 0 (control), 250 and 500 µm proline and 0 (control), 2 and 4% ascorbic acid and their combinations, then stored at 1...

the present study was carried out to examine the effects of a vitamin premix (vp) reduction or withdrawal from finisher diet (29-43 days) on performance, immuno-competence, and characteristics of leg bones and meat lipid oxidation of chickens fed on corn-soybean meal based diet. a total of 900 male broiler chickens (ross 308) were allocated to five treatment groups (0, 33%, 66%, 100% and 133% v...

to evaluate the effect of intravenous infusion of a soybean based lipid emulsion (lipovenoes 10%) on some blood constituents in sheep, a replicated 2 × 2 latin square design experiment was conducted in four clinically healthy ewes. lipid emulsion (le group) or normal saline (ns group) was infused intravenously at a rate of 0.025 ml kg-1 per min for 6 hr and the concentrations of blood triglycer...

this study was carried out to evaluate the effects of red onion (allium cepa l.) juice and green tea (camellia sinenses) extract on lipid oxidation and sensory characteristics of refrigerated (4ºc) sturgeon fillets (acipenser persicus). fresh fillets were tumbled in 1%, 2.5%, and 5% (v/v) aqueous solutions of onion juice (oj) and tea extract (te), and then stored for up to 8 days at 4°c in a re...

introduction: ramadan is the ninth month of the lunar islamic calendar, during which muslims are obliged to perform specific rites and rituals. fasting is considered the most important ritual during the holy month of ramadan. fasting variably influences the health of individuals, which could be attributed to the changes in the concentrations of certain biochemical markers. this study aimed to e...

background: despite almost the three decades passed since the chemical attacks of iraqi’s army against the iranian troops, some veterans are still suffering from long-term complications of sulfur mustard (sm) poisoning, including certain skin complaints specially dryness, burning, and pruritus. we thus aimed to evaluate the skin’s water and lipid content in patients with a disability of >25% du...

background: obesity and metabolic syndrome are serious public health problems. it is suggested that high calcium diet can improve lipid profile, blood pressure and insulin resistance. methods: in this clinical trial, 75 healthy overweight or obese premenopausal women were randomly allocated to one of the following dietary regimens for 8 weeks: 1) a control diet 2) a calcium-supplemented diet co...
