Effects of lipids and (n-3) highly unsaturated fatty acids compositions of three artificial foods on survival, growth and body composition of common dentex’s fingerlings (Dentex dentex, L)

Dentex juveniles of initial live weight 5 - 6 g and 108 days old after hatching, were fed three different diets for ten weeks (moist pellet (MP), imported dry pellet (IDP) and locally dry pellet (LDP)) containing three different lipid levels (26, 21 and 10% respectively) and crude protein levels (46, 45 and 47% respectively). Fatty acid composition showed that, DHA and EPA contents of moist pellet are...

Gangliosides as potential inhibitors of Naja naja venom PLA2 (NV-PLA2) induced human erythrocyte membrane damage

We determined the ability of mixed gangliosides (16% GD1b, 19% GT1b, 21% GM1, and 40% GD1a) and individual gangliosides GM1 and GD1b to modulate the NV-PLA2 induced human erythrocyte ghost membrane damage. CM-Sephadex purification of crude Naja naja venom yielded eight peaks of which peak VII, a major phospholipase A2 (NV-PLA2) accounted for 22% of the total protein recovered and 8% of the total...

Trans-resveratrol as phenolic indicator of somatic embryogenesis induction in cotton (Gossypium hirsutum L.) cell suspensions

Trans-resveratrol is a phytoalexin which was found in some grapes and in many other plants. This phenolic compound has gained much attention, as it was indicated to be associated with fungus and disease resistance. Also, it has been shown that phenols compounds could play an important role in somatic embryogenesis induction of various plants. In cotton, embryogenic structures take place in cell suspension cultures....

Allethrin-induced biochemical changes and properties of human erythrocyte membrane

Erythrocyte membranes from twelve human volunteers exposed regularly to allethrin, a mosquito repellent of type-I pyrethroid, were analyzed for cholesterol (C), phospholipids (P), and individual phospholipid classes to assess changes induced by this toxicant. A decrease in C and P moieties with no change in C: P ratio was observed with allethrin exposure. A significant reduction in the amount of phosphotidyl serine (PS)...

Aeration as a factor in textile dye bioremoval by Aspergillus niger

Experiments were done to study the bioremoval/ biosorption of dis-azo dye byAspergillus niger strain 20 in two concentrations using 5 liter bioreactor at five aeration rates. The experimental results are compared for various operating conditions. The dye used was direct brown and the inlet air flow rate was: 1/8, ¼, ½, 1, 2 v/v/min. The aeration rate of ½ v/v/min yielded 9.2 g fungal...
