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...

In paragraph two, page 1, they imply mediation (â##â#¦strongly influenced by SES..â##) but in paragraph three, confounding is implied (â##....competing factorsâ#¦â##). This...

Data envelopment analysis (DEA) is a methodology for measuring the relative efficiency of decision making units (DMUs) which ‎consume the same types of inputs and producing the same types of outputs. Believing that future planning and predicting the ‎efficiency are very important for DMUs, this paper first presents a new dynamic random fuzzy DEA model (DRF-DEA) with ‎common weights (using...

The aggregation of the â-peptide into amyloid is a key pathological event in Alzheimer’s disease. This process (â-amyloidosis) involves the conversion of soluble random coil, R-helical or â-sheet conformations into insoluble, aggregated â-pleated sheet structures. The pH is a significant extrinsic factor that influences â-amyloidosis, which must be related to the presence of ionizable groups in...
