Periwinkle (Catharanthus roseus L., Apocynaceae) contains more than 130 different terpenoid indole alkaloids (TIAs), of which two dimeric alkaloids, Vinblastine and Vincristine, have antineoplastic activity and are useful in treatment of various cancers. Specific production of some alkaloids in differentiated tissues such as leaf and stem led to use direct regeneration of explants in order to i...
In order to optimize the micropropagation of Qare-Qat (Vaccinium arctostaphylus J.J.Sm), samples were collected from two regions of Iran (Asalem and Kelardasht). Anderson (AN) media containing different concentrations of zeatin (0, 0.5, 1, 2 and 4 mg L-1) and different levels of pH (4.5, 5 and 5.5) were compared. The in vitro shoots were transferred on AN media supplemented with zeatin (1 and 2...

taxus chinensis var. mairei is a rare and endangered medicinal plant species distributed in china. in order to promote fast propagation and preserve the natural resources, conditions for in vitro germination and seedling development of embryos of t. chinensis var. mairei from anhui or zhejiang were investigated. results showed that in vitro germination rate of excised embryos cultured under 14 ...
chromium (cr) is one of the elements presents in crust of the earth. due to its toxicity, chromium is considered as water contaminant that may disturb metabolic activity. in the present study, adsorption of dissolved chromium (vi) onto elaeagnus angustifolia fruit charcoal, jujube fruit charcoal and the standard granular activated carbon (gac) has been investigated and compared. the effect of c...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...

this study evaluated the effects of 0.25% activated charcoal added to sesame seed meal (ssm) in partial replacement of soybean meal (sbm) of juvenile clarias gariepinus diet on growth and haematological parameters for 70 day experimental period. six experimental diets were formulated as: control diet 1 (100% ssm without activated charcoal), control diet 2 (100% ssm plus 0.25% activated charcoal...
