Studies on GSK3¥â expression in the kainate induced excitototoxic hippocampal injury model of mice Jung Hoon Lee Department of Anatomy Graduate School Seoul National University Glycogen synthase kinase 3¥â (GSK3¥â) is believed to play important roles in the regulation of synaptic plasticity, cell survival and circadian rhythms in the mature CNS. However, although several studies have been focus...

To elucidate the significance of tRNA modification for human lymphoid maturation and malignant transformation, the amount of tRNAs having guanosine in place of queuosine, i.e., (Q-)tRNA, was determined in several human lymphomas and leukemias by exchanging the respective unmodified guanosine residue for [3H]guanine, a reaction catalyzed by a specific tRNA transglycosylase from Escherichia coli....

Cholecystokinin (CCK) is a growth factor for normal pancreas. Nu merous studies also suggest that CCK promotes pancreatic carcinogenesis in the rat. Our previous studies suggested that growth of preneoplastic pancreatic foci was stimulated by CCK more than that of normal pan creas. We hypothesized that such differential growth might be due to increased numbers of CCK receptors in neoplastic tis...

â â â â â â â â â â â â â â â  â  abstract â  the effect of technology spillovers is widely considered as one of the main channels through which domestic firms benefit from fdi, and plays an important role in economic development of host countries. based on the analysis framework for technology spillovers established by borensztein et al. (1998), this paper will analyse and try to figure out th...

As this paper was a very close version of “Investigating task difficulty: learners’ and teachers’ perceptions” by Dr. Parvaneh Tavakoli (published in “International Journal of Applied Linguistics”, Vol. 19, No. 1) in terms of content, research design, analytic framework and research findings without appropriately referencing resources used or obtaining author's consent, the paper wa...

â â â  â  â â â â â â â  abstract â  the abtalkh formation in the kopeh-dagh basin in northeastern iran with an age of late cretaceous (turonian – santonian) is selected to evaluate resolution of magnetic susceptibility for assessing sea level fluctuations. thirty-nine shale samples were collected and studied for magnetic susceptibility and palynology. assuming the average ms magnitude as the...
