Improved and efficient methods were developed for isolating high quality DNA and RNA from different sources of Iranian Yew (Taxus baccata L.). The methods were based on CTAB extraction buffer added with high levels of polyvinylpyrrolidone (PVP) and β-mercaptoethanol to properly remove polysaccharides and prevent oxidation of phenolics. The pellets obtained(More)
Taxol is one of the most effective anticancer drugs that isolated from Taxus sp. due to the slow growth of Taxus trees and low concentration of Taxol in the tissues, the biotechnological approaches especially plant cell culture have been considered to produce Taxol in commercial scale. We investigated the effects of basal medium type used in culture media(More)
The purple membrane of Halobacterium Salinarum carries out a protein, bacteriorhodopsin (bR), which is a model for structure-function studies of membrane proteins. The heterologous expression of integral membrane proteins (IMPS) is difficult. In this study, we reported the heterologous overexpression of bacterio-opsin (bO) in Escherichia coli BL21 (DE3).(More)
Taxol is an anticancer drug for treatment of a variety of human cancers. The effects of explant source and growth regulators were examined in order to optimize the induction and selection of fast growing callus lines of Taxus baccata. Explants were prepared from stems, needles and base of needle of yew tree. We used basal B5 medium with addition of(More)
VIGS (virus induced gene silencing) is considered as a powerful genomics tool for characterizing the function of genes in a few closely related plant species. The investigations have been carried out mainly in order to test if a pre-existing VIGS vector can serve as an efficient tool for gene silencing in a diverse array of plant species. Another route of(More)
BACKGROUND Ginger (Zingiber officinale Rosc.) belongs to the family Zingiberaceae. The health-promoting perspective of ginger is attributed to its rich phytochemistry. This study aimed to review the current evidence on ginger effects as an anti-inflammatory and anti-oxidative. METHODS We searched MEDLINE for related publications using "ginger" and(More)
The ability of a potent hydrophobic adsorbent, AC (activated charcoal), to induce total taxane synthesis and to improve the recovery of the products from suspension culture of Taxus baccata L. was examined. The results strongly showed that the application of encapsulated AC as an adsorbent not only led to improvement of in situ recover but also led to(More)
Human insulin-like growth factor I (hIGF-I) is a kind of growth factor with clinical significance in medicine. Up to now, E. coli expression system has been widely used as a host to produce rhIGF-1 with high yields. Batch cultures as non-continuous fermentations were carried out to overproduce rhIGF-I in E. coli. The major objective of this study is over-(More)
BACKGROUND The protein hormone granulocyte colony-stimulating factor (GCSF) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. METHODS An efficient process was developed for heterologous expression of the human GCSF in E. coli BL21 (DE3). The feeding rate was adjusted to achieve the maximum(More)
Organic salts of bismuth are currently used as antimicrobial agents against Helicobacter pylori. This study evaluated the antibacterial effect of elemental bismuth nanoparticles (Bi NPs) using a serial agar dilution method for the first time against different clinical isolates and a standard strain of H. pylori. The Bi NPs were biologically prepared and(More)
