gavane-gaz-angubin (persian manna) belongs to astragalus genus (leguminosae). this plant is one of the most important species in iran for its medicinal value. considering the low propagation rate of this plant from seed and cutting, the feasibility of in-vitro propagation of this plant was investigated. effect of different types and concentrations of cytokinins such as bap, kin, and ze (0.5, 1,...

objective(s): binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. materials and methods: template free zsm-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/zsm-5 hybrid composites with nano chitosan...

two simple visible spectrophotometric methods are developed and validated for the quantification of modafinil using 1,2-naphthoquinone-4-sulphonic acid (nqs method) and 2,4-dinitrophenol (dnp method) as analytical reagents. the nqs method involves the reaction of modafinil with 1,2-naphthoquinone-4-sulphonate in alkaline medium at room conditions to form a yellow colored product exhibiting maxi...

diseased samples with root rot symptoms were collected from different sugar beet growing areas. from rotted roots, 20 fungal isolates were identified as fusarium solani based on morphological characteristics .pathogenecity of the isolates was studied in in vitro condition on sugar beet roots. the results showed pathogenic variability among the isolates. cluster analysis divided the isolates int...

introduction atmospheric circulation patterns leads to different weather conditions and rainfall regime change is controlled by seasonal and irregular variations of atmospheric circulation pattern. variety and climate change, such as drought and flood result in changes in the spatio-temporal of precipitation, one of the important parameters conditions mentioned, heterogeneity in moisture transm...

some drugs have low bioavailability due to their poor aqueous solubility and/or slowdissolution rate in biological fluids. stiripentol (stp) is a novel anticonvulsant drug that isstructurally unrelated to the currently available antiepileptics. it has poor aqueous solubilityand its solubility has to be enhanced accordingly. polyethyleneglycol 6000 (peg-6000) iscommonly utilized as a hydrophilic...

plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...

diabetes is a metabolic disorder specified by hyperglycemia following a defect in insulin secretion, insulin resistance or both. the aim of this study was to examine the effect of high-intensity interval training (hiit) on serum adiponectin levels and insulin resistance of women with type 2 diabetes. for this purpose, 35 overweight women with type 2 diabetes (age range 45-60 years, bmi 25-30 kg...
