plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. micropropagation allows rapid production of high quality, disease-free and uniform planting material. the micropropagation of high quality planting materials of ornamentals, and forest and fruit trees has created new opportun...

introduction & aim: the ethanol and aqueous extracts of alhagi camelorum fisch. (fabaceae) whole plant, scrophularia desertii del. (scrophulariaceae) whole plant and ethanol extracts of echinophora platyloba dc. (apiaceae) whole plant, teucrium polium l. (lamiaceae) whole plant and berberis integerrima bunge root brake were investigated for anti-brucella in-vitro and in-vivo conditions. exp...

the aim of this study was to assess the effect of several doses of spearmint essential oil (seo; 0, 250, 500, 750 or 1,000 µg ml-1 buffered rumen fluid) on the fermentation kinetic and digestibility using in vitro gas production technique. a total mixed ration (30% roughage: 70% concentrate) was incubated with buffered rumen fluid. in vitro gas production, asymptotic gas production (a), rate of...

salt stress negatively impacts crops yield throughout the world. nine varieties of potato (solanum tuberosum l.) were screened for salt stress tolerance by measuring in-vitro growth of the aerial plant parts, as well as roots. salt stress was evaluated by adding 25, 50, 75, 100, 125, 150 and 200 mm of nacl to murashige- skoog (ms) medium and compared to ms medium without nacl. plant length and ...

this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...

trichomoniasis is one of the most common urinary-genital tract disease. the causal agent of trichomoniasis is flagellate protozoan called trichomonas vaginalis. metronidazole and tinidazole are the drug of choice for treatment. carcinogenic and embryo-teratogenic effects of the mentioned drugs and resistance to metronidazole has been reported. according to cytotoxic effects of medicinal herbs i...

in the near future, design of a new generation of drugs targeting proteins will be required. considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. so far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. in these studies, use of spectroscopic method...

due to good biocompatibility, corrosion and mechanical properties, magnesium (mg) is considered promising degradable material for orthopedic applications. in this work, mg-mgznx (x= 1, 2, 3 and 4) nanocomposites scaffolds with different porosities were synthesized via powder metallurgy method. the microstructure, composition, in vitro corrosion and mechanical properties of porous magnesium-zinc...
