common yew taxus baccata l. is an evergreen, slow growing   tree, indigenous of hyrcanian forests in iran. discovery of paclitaxel as an   anti tumor agent in the bark of taxus has increased importance of this   plant for treatment of breast and ovary cancer, especially 7000 women die annually   due to breast cancer in iran. regarding destructive method of paclitaxel   production and protection...

BACKGROUND We have previously shown that the medium used for culturing IVF embryos affects the birthweight of the resulting newborns. This observation with potentially far-reaching clinical consequences during later life, was made in singletons conceived during the first IVF treatment cycle after the transfer of fresh embryos. In the present study, we hypothesize that in vitro culture of embryo...

mycophenolic acid is a secondary extracellular metabolite of penicillium strains with numerous pharmaceutical properties such as antibiotic and immunosuppressive uses. the aim of this work is the survey of the effect of phenylglyoxal and n-ethylmaleimide concentration in culture medium on mycophenolic acid production by penicillium brevi-compactum atcc16024 was investigated. batch submerged fer...

in order to micropropagate of four vigorous rootstocks of pear, including pyrus betulifolia, konjuni, dargazi and gh1, effects of basic plant culture media (ms, ql and modified ql), cytokinins and auxins on productivity, proliferation and rooting were studied in seed and plant improvement institute, karaj. the highest amount of productivity for all rootstocks was observed in ql medium. among pe...

The composition of a culture medium is one of the most important parameters to be analyzed in biotechnological processes with industrial purposes, because around 30-40% of the production costs were estimated to be accounted for the cost of the growth medium [1]. Since medium optimization using a one-factor-at-a-time approach is time-consuming, expensive, and often leads to misinterpretation of ...

Oocytes and embryos are typically exposed sequentially to varying culture media in standard in-vitro protocols. Expenditures of energy may be required following each medium change to adjust to the changing environment. Therefore, a single base medium was evaluated for its ability to support in-vitro maturation, fertilization and pre-implantation development (IVM/F/C) of bovine oocytes and embry...

The study of large animal embryonic stem cells (ESCs) in vitro has implications for the understanding of lineage differentiation and transgenesis. The first step for ESC derivation is the attachment of the embryo to a substrate on which they can form outgrowths. However, the culture conditions for large animal embryo attachment and ESC derivation have not been studied extensively. Defining cult...

Candida auris is an emerging multidrug-resistant yeast causing nosocomial infections and associated with high mortality in immunocompromised patients. Rapid identification characterisation are necessary for diagnosis containing its spread. In this study, we present a selective culture medium all C. clades. This sensitive limit of detection ranging between 101 102 CFU/mL. The 100% specificity SC...
