The present study was aimed to evaluate the moderating properties of lavender (Lavandula officinalis) essential oil (LEO) against immunotoxic effects of the organophosphate pesticide, malathion in rainbow trout, Oncorhynchus mykiss. For this purpose, fish were supplemented with LEO at dietary concentrations of 0.5, 1, 2 and 4 ml/kg diet LEO for 56 days. A non-LEO supplemented group was also considered as control. After 57 days feeding trial, biochemicals were assayed in the blood and kidney tissue and then fish exposed to a sub-lethal concentration of malathion [0.24 mg/l equal to 30% of LC50 (0.8 mg/L)]. After 57 days feeding trial, the serum total immunoglobulin, respiratory burst activity, lysozyme activity and complement activity significantly elevated in fish treated with 1 and 2 ml LEO/kg diet compared to non-LEO supplemented individuals (P0.01). Significant elevations were observed in the expression of the immune genes (iNOS and C3 genes) in fish treated with 0.2–2 mg LEO/kg diet compared to non-supplemented ones (P0.01). The expression of iNOS and C3 genes significantly reduced in control and fish fed 0.5, 1 and 4 ml LEO/kg diet in response to malathion (P0.01). The findings of the present study suggested an immunoprotective role for dietary LEO at optimized dietary concentrations of 1 and 2 ml LEO/kg diet against oxidative stress and toxicity induced by malathion. Nevertheless, LEO at high dietary concentration (4 ml/kg diet) had reducing effects on the fish immunity.

This study has focused on just synthesized materials that were produced from bacteriological practice. So, the density functional theory calculations with hybrid B3LYP at 6-31G sets of basis retain lived utilized to examine the properties of structural and electronic properties of biomaterial original. The determinations include been displayed thereof that is a lowering in the energy of total beyond merging the OH and CH3 with Phenazine. HOMO and LUMO levels of energy investigations exhibit that the estimation HOMO energy was boosted slightly at 1-Hydroxyphenazine and 2-Hydroxyphenazine but increasing more in 5-Methylphenazin-1(5H)-one, while the value for the LUMO level energy lowered greatly in these strategies of adding the OH at Phenazine. In addition, the lowering of the gap of energy between HOMO and LUMO ensures a bond of strongly between the hydroxyl group and Phenazine. Ultimately, the Biomaterial stability was investigated by estimating the reaction of chemical factors such as the potential of Ionization (I), Affinity (A), global hardness, and Electronegativity χ. As a result, the hydroxyl group and a methyl group can be considered as factors of important changes within biological systems in many chemical and physical properties.

The modes are arrangements of Maxwell’s conditions relying upon limit states of the waveguide(cylindrical waveguide n = n1 for core and n = n2 for cladding). In this paper, qualities of barrel shaped waveguides with metamaterials are contemplated. Likewise, just because, half breed modes are examined, and a few new ends in cross breed mode conduct are drawn. Especially, conditions under which the crossover mode isolates into the transverse electric and transverse attractive (n=0) modes are acquired. For incredibly isotropic round and hollow waveguide where the permittivity in medium (1) is negative while the penetrability in medium (2) is negative. At some random recurrence the waveguide bolsters an unending number of eigen-modes.

Analytical and numerical analysis of electromagnetic wave propagation in cylindrical waveguides filled with isotropic metamaterial is presented. Emphasis is given to the characteristics of power flux in the waveguide. In the structure of the waveguide, The characteristics equation for the modes in this waveguide is obtained. The behavior of the dispersion curves and the energy flux are examined theoretically. The negative energy flux propagation through the cylindrical waveguide is confirmed.
