carbon is the most important greenhouse element which sequestrates by photosynthesis procedure and is the easiest and cheapest way of decreasing atmospheric gas level. the vegetation cover that has woody texture is more capable for carbon sequestration. the most plant species of arid rangelands are the shrub growth forms. the purpose of this research was to assess carbon sequestration potential...

Background: Regarding the strong differentiation and anti-leukemic activity of Dendrostellera lessertii extract, an active agent with similar capabilities was isolated from the crude extract of the plant leaves. The aim of this study was to determine whether the anti-proliferative effect observed for this compound, is differentiation-dependent among the drug-treated cells, using U937 cells. Me...

Dendrostellera lessertii (Thymelaeaceae) is a toxic plant that grows in parts of Iran. The anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-HK), have been established using several cancer cell lines. Methods: In a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...

Several mammalian enzymes are anchored to the outer surface of the plasma membrane by a covalently attached glycosylphosphatidylinositol (GPI) structure. These include acetylcholinesterase, alkaline phosphatase (AP) and 5'-nucleotidase among other enzymes. Recently, it has been reported that these membrane enzymes can be released into the serum by the GPI-dependent phospholipase D under various...

Several mammalian enzymes are anchored to the outer surface of plasma membrane by a covalently attached glycosyl-phosphatidylinisitol (GPI) structure. These include acetylcholinesterase, alkalinee phosphatase and 5´-nucleotidase. Recently, it has been reported that these membrane enzymes can be solubilized into the serum by GPI-dependent PLD, under various medical disturbances such as cancer an...
