Intracellular RNA cleavage by the hairpin ribozyme.
Studies involving ribozyme-directed inactivation of targeted RNA molecules have met with mixed success, making clear the importance of methods to measure and optimize ribozyme activity within cells. The interpretation of biochemical assays for determining ribozyme activity in the cellular environment have been complicated by recent results indicating that hammerhead and hairpin ribozymes can cl...

15 صفحه اولa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
INHIBITION OF14C UPTAKE BY CANDIDA ALBICANS: A NEW METHOD FOR INVESTIGATION OF INTRACELLULAR KILLING BY PHAGOCYTES
A radio assay employing 14C-uridine to measure the intracellular killing of Candida albicans by phagocytes is presented. The principle of this new method is that after killing of Candida albicans by phagocytes RNA synthesis stops and therefore uridine uptake is diminished whilst viable candida in cultures would take up uridine and as a result, high CPM counts can be obtained within 135 min...
متن کاملDistinct reaction pathway promoted by non-divalent-metal cations in a tertiary stabilized hammerhead ribozyme.
Divalent ion sensitivity of hammerhead ribozymes is significantly reduced when the RNA structure includes appropriate tertiary stabilization. Therefore, we investigated the activity of the tertiary stabilized "RzB" hammerhead ribozyme in several nondivalent ions. Ribozyme RzB is active in spermidine and Na(+) alone, although the cleavage rates are reduced by more than 1,000-fold relative to the...
