Pollen-mediated gene flow in space is well documented and isolation distances are recommended to ensure genetic purity of Brassica napus seed crops. Isolation in time could also contribute to gene flow management but has been little investigated. We assessed the effects of asynchronous and synchronous flowering on intraspecific B. napus gene flow by seeding adjacent plots of transgenic spring c...

Background: The most devastating manifestations of diabetes mellitus are vascular complications. Although there are many factors involved in the pathogenesis of diabetic vasculopathy, many studies suggest a role for glucose–induced oxidative stress. Studies in animal models, have demonstrated that the administration of antioxidants restores normal endothelial functions. The study was designed t...

in order to study the effect of drought stress and harvesting stages on quantitative and qualitative yields of coriander (coriandrum sativum l.) this experiment was conducted on split plot based on a randomized completely block design with 3 replications in torbat-e heydariyeh university, iran, during growing season of 2010-2011. treatments were drought stress (in three levels no stress: contro...

Astaxanthin, a carotenoid without vitamin A activity, may exert antitumor activity through the enhancement of immune responses. Here, we determined the effects of dietary astaxanthin on tumor growth and tumor immunity against transplantable methylcholanthrene-induced fibrosarcoma (Meth-A tumor) cells. These tumor cells express a tumor antigen that induces T cell-mediated immune responses in syn...

This experiment was conducted, to study the effect of planting time and planting density on savory (Satureja sahendica Bornm.) in 2012 in Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was carried out in split plot in time in the form of a randomized complete block design with three replicates. The main plots were planting times in two levels ...

Recently a potent anti-inflammatory effect of hydroalcoholic extract of the aerial parts of the sterile stems of Stachys inflata has been reported. This study examined whether hydroalcoholic extract isolated from aerial parts of non-flowering stems of Stachys inflata (standardized to contain 4.5% caffeic acid derivatives) reduce myocardial infarct size arising from coronary artery occlusion (30...

It is frequently observed that males of dioecious plant species flower earlier in the season than females, although the generality of this pattern has not been quantified. One hypothesis for earlier male flowering is that females require more time for resource acquisition before reproduction; another is that selection for access to unfertilized ovules favors early-flowering males. Here I show t...
