Background and Objective: Due to progressive increase in the number of cases of cancer, there is a need to develop anti- tumor compounds. Statins have a variety of different effects on proliferation, migration and survival of cells and have been suggested as proper candidates for the inhibition of this disease. The aim of this study was to determine cytotoxicity effects of Atorvastatin with var...
aquatic plants have been used prevalently in china since 3000 years ago due to having various chemical compounds for diseases prevention and cure. dunaliella salina is one of the micro algae in marine ecosystems containing beta-carotene, retinal, apocarotenoides, ketones, aldehydes and epoxides which enable it to absorb free radicals and produce singlet oxygen. in many studies, the anti-cancer...
different explants of crocus sativus l. such as corm, style, ovary, petal, anther and leaf were cultured on ls and ms media supplemented with naa and bap or 2,4-d plus bap at different combinations. shoot and corm induction occurred in addition to the formation of other organs. efficient plantlet regeneration with strong roots occurred at 1 mg 1-i of both naa and bap. an increase in 2,4-d level...
Alkaloids of the aerial parts of chelidonium were extracted in the salt form, and their aqueous solutions were prepared in different concentrations. Rat hepatocytes were obtained by liver perfusion. The alkaloidal solutions were added to suspensions of hepatocytes in petri dishes and the mixtures were incubated. Two types of controls have been used in one type. no alkaloidal extract was ad...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
The present investigation was carried out to study the In vitro shoot multiplication and callogenesis in Gladiolus. For this purpose, cormel, meristem and leaf explants were chosen. Different concentrations of BAP i. e., 0.5, 1.0, 1.5, 2.0 or 2.5 mgL (2.22, 4.44, 6.66, 8.88 or 11.10 μM) were supplemented to MS medium. Both cormel and meristem explants showed maximum multiplication on MS medium ...
abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
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...
Background and objectives: A modern biotechnological technique to obtain useful natural products from plants is to isolate them from their callus. Zataria multiflora is a bushy herb of the Lamiaceae family known for its stimulant, antibacterial, antioxidant and expectorant effects in Iranian folk medicine. The present study has investigated the induction of callus tis...
an experiment was conducted to study the micropropagation of satureja khuzistanica. the seeds were planted in 1/2ms medium. after germination and growth of plantlets, they were subcultured in fresh medium. then, they cultured into medium supplemented by different concentrations of ba and kinetin. results showed that, the highest proliferation (2.4 shoots) was observed at concentrations of 0.5 m...
