Soil salinity is a widespread stress in semi-arid forests worldwide, but how to manage nitrogen (N) nutrition improve plant saline tolerance remains unclear. Here, the cuttings of widely distributed poplar from central Asia, Populus russikki Jabl., were exposed either normal or low (LN) concentrations for two weeks semi-controlled greenhouse, and then they added with moderate salt solution not ...

Sapodilla is one of the important fruit crops in tropical area which has problem with seed germination. So Manilkara hexandra (kherol) is generally used as a rootstock for sapodilla. This experiment was performed to assess the morphological changes and antioxidant enzymatic activity of Manilkara hexandra seedling under salinity condition. A pot experiment was carried out in a greenhouse using d...

background and objectives:scrophularia variegata m. beib. (scrophulariaceae) is a medicinal plant, used for various inflammatory diseases in iranian traditional medicine. in the present study, we evaluated the immune modulation and antioxidant effects of the hydroalcoholic extract of s.  variegata. methods: the splenocytes were harvested from the spleen of balb/c mice and were cultured. the spl...

Long-term use of inorganic fertilizers can increase soil acidity, be harmful to the environment, and leaving bad effects on human health. Organic fertilizer application is one safer alternatives with numerous benefits, such as supplying nutrients for plant growth. Sunflower most important grown oilseed crops in world. plants need a supply essential their optimal As result, aim this research exp...

to determine the importance of q 10 h 2 as an antioxidant in cancer, we measured the activity of lipoamide dehydrogenase (q 10 h 2 recycling enzyme) in hl-60 and normal lymphocyte. the cultured cells of hl-60 and human normal lymphocytes were assayed in cell lysate of given number of both hl-60 and normal lymphocyte. the activity of lipoamide dehydrogenase and the protein concentration were det...

Three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (WSSV) and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei. Each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...

Osmolytes are low molecular weight organic molecules accumulated by organisms to assist proper protein folding, and to provide protection to the structural integrity of proteins under denaturing stress conditions. It is known that osmolyte-induced protein folding is brought by unfavorable interaction of osmolytes with the denatured/unfolded states. The interaction of osmolyte with the native st...

Osmolytes have been reported to stabilize biomolecules and even whole organisms against exposure to adverse environmental conditions. In this work, we report for the first time the use of some of these osmolytes, viz., the disaccharides trehalose and sucrose, in the stabilization of bovine trypsin against exposure to the anionic detergent sodium dodecyl sulfate and autolysis. Exposure of trypsi...

This study was performed to investigate the effect of Ag+ as an elicitor on the activity of antioxidant enzymes, content of H2O2, accumulation of total tocopherol and antioxidant activity in hairy root cultures of Silybum marianum (L.) Gaertn. The hairy roots were treated with 2 mM Ag+. The treated and non-treated hairy roots were harvested in the same time and data on H2O2 content, DPPH, tocop...
