background: as moringa peregrina is a valuable medicinal plant in traditional medicine, it is necessary to determine responses of this plant to salinity.  objective: to determine some biochemical and growth responses of moringa peregrina to salinity at the seedling stage. methods: this experiment was conducted in institute of medicinal plants-acecr, on base of factorial experiment as completely...

The modification of typical age-related growth by environmental changes is poorly understood, In part because there is a lack of consensus at individual tree level regarding age-dependent growth responses to climate warming as stands develop. To increase our current understanding about how multiple drivers of environmental change can modify growth responses as trees age we used tree ring data o...

Background: Propolis, a honeybee product, has been used empirically for centuries and was always mentioned as an immunomodulatory. OBJECTIVES: In this study, the effects of propolis on growth indices, innate immune responses and haematological parameters of Barbus barbulus were investigated. METHODS: Three hundred and sixty juvenile Barbus barbulus, weighing 102±8.2g were randomly divided int...

Classical Darwinian adaptation to a change in environment can ensue when selection favours beneficial genetic variation. How plastic trait responses to new conditions affect this process depends on how plasticity reveals to selection the influence of genotype on phenotype. Genetic accommodation theory predicts that evolutionary rate may sharply increase when a new environment induces plastic re...

 Irrigation is an inevitable part of agriculture which determines crop yield and thus food security. In modern era of agriculture, crop yield is determined on the basis of crop production per unit of water-use instead of crop production per land unit area. Deficit irrigation is introduced as a strategy for controlling water resources that leads to water resource preservation. Date palm requires...

Background: Hydatid cyst is the larval stage of the tape worm parasite, Echinococcus granulosus. Human is infected by ingestion of parasite ova excreted in dog feces. The anticancer activity of different antigens of hydatid cyst has been reported in the previous works. In this research, the role of immune system in induction of this anticancer activity has been investigated.Materials and Method...

Soil salinity affects a large part of the region in Iran. Salinity covers 12.5% oftotal area of the country. Priming of seeds in sodium chloride and water (hydro-priming)has been reported to be a simple technique for enhancing the seedling establishment andgermination performance in the seeds of many crops and small seeded grasses under thestress conditions. Therefore, the aim of this research ...

in this study, responses of four canola genotypes to salt stress in germination test and callus culture stages were investigated. the response of genotypes under salinity levels was significantly different. higher salinity resulted in less germination and growth of seedling. after callus culturing on liquid saline media, callus fresh weight and callus induction efficiency were significantly dif...

regenerative medicine provides substitutes for organ transplantation, which is restricted in applicability due to immune responses against allograft and the large discrepancy between the need for organs and the number of available transplantation. an artificial environment is allowing cells to induce tissue regeneration. growth factors (gfs) play a significant role in the cell fates in their mi...
