| 20100004325 | Use of Baicalein As Prolyl Hydroxylase 2 Inhibitor - The present invention is to prove a new molecular and cellular effect of baicalein, which is selected by a prolyl hydroxylase 2 (PHD2) inhibitor screening method using a compound library. Specifically, the present invention quantitatively analyzed the inhibitory effect of the baicalein against PHD2, confirmed the inhibitory effect against FIH (factor inhibiting HIF), analyzed the HIF (hypoxia inducible factor) protein expression induced by baicalein in a cell, and then, confirmed whether the VEGF is expressed by using reporter assay and ELISA. The above effect of baicalein proves that it can be used for a drug treating ischemic diseases, and, therefore, it can be used for other related diseases. | 01-07-2010 |

| 20120037970 | MICROELECTRONIC MEMORY DEVICES HAVING FLAT STOPPER LAYERS AND METHODS OF FABRICATING THE SAME - Memory devices comprise a microelectronic substrate including a cell array region and a peripheral region adjacent the cell array region, the cell array region including therein an array of memory cells and the peripheral region including therein peripheral circuits for the array of memory cells, the microelectronic substrate including a lower layer that extends across the cell array region and across the peripheral region and that includes a flat outer surface from the cell array region to the peripheral region. A signal transfer conductor layer extends in the cell array region beneath the flat outer surface of the lower layer and extends in the peripheral region above the flat outer surface of the lower layer. An insulating layer is provided on the lower layer, the insulating layer extending across the cell array region and the peripheral region and also including a flat outer surface from the cell array region to the peripheral region. A flat stopper layer is provided on the flat outer surface of the insulating layer and extending across the cell array region and the peripheral region. Finally, an array of memory cell capacitor storage nodes is provided in the cell array region that extend beyond the flat stopper layer and that penetrate through the flat stopper layer and the insulating layer. Related methods are also provided. | 02-16-2012 |
