امروزه یکی از مهم ترین علل شایع مرگ در سطح جهان بیماری سرطان بوده که شیوع و میزان مرگ و میر آن در ایران، قابل توجه می باشد. از طرف دیگر، با توجه به بومی بودن گیاه زعفران در منطقه خراسان جنوبی، در مطالعه حاضر خواص ضد توموری کلاله زعفران و برخی از مکانیسم های عمل آن در مدل های مختلف ماکرومولکولی، سلولی و حیوانی مرور شده است. در طب سنتی از کلاله زعفران به عنوان ترکیب دارویی در درمان بسیاری از بیما...
Maize rough dwarf disease (MRDD), caused by several Fijiviruses in the family Reoviridae, is a global disease that is responsible for substantial yield losses in maize. Although some maize germplasm have low levels of polygenic resistance to MRDD, highly resistant cultivated varieties are not available for agronomic field production in China. In this work, we have generated transgenic maize lin...
Spectinomycin, an inhibitor of plastid protein synthesis, can be used to mark specific cell layers in the shoot meristem of Brassica napus. Pale yellow-green (YG) plants resulting from spectinomycin-treatment can be propagated indefinitely in vitro. Microscopic examination showed that YG-plants result from inactivation of plastids in the L2 and L3 layers and are composed of a pale green epiderm...
The use of medicinal plants as a fundamental component of the African traditional healthcare system is perhaps the oldest and the most assorted of all therapeutic systems. In many parts of rural Africa, traditional healers prescribing medicinal plants are the most easily accessible and affordable health resource available to the local community and at times the only therapy that subsists. Nonet...
Due to its ability to be rapidly generated and propagated over long distances, H2O2 is an important second messenger for biotic and abiotic stress signaling in plants. In response to low water potential and high salt concentrations sensed in the roots of plants, the stress hormone abscisic acid (ABA) activates NADPH oxidase to generate H2O2, which is propagated in guard cells in leaves to induc...
in a preliminary study carried out in a simple field laboratory in bandar-abbas, southern iran, five isolates of p. falciparum collected from the patients was cultured in rpmi 1640 medium with human serum in the tightly closed screw capped vials without any devised system for adjustment of co2 and o2 mixture. the same isolates were also cultured, simultaneously, in petri-dishes using jensen-tra...
An efficient and reproducible in vitro protocol for largescale multiplication of Liquorice (Glycyrrhiza glabra L.)has been described. Multiple shoots formation was significantly influenced by growth regulators, photoperiod,explant position, season of explant collection and culture passage. Nodal explants were collected atmonthly intervals to initiate in vitro cultures. The hig...
