Box C/D guide RNAs are abundant noncoding RNAs that primarily function to direct the 2'-O-methylation of specific nucleotides by base-pairing with substrate RNAs. In archaea, a bipartite C/D RNA assembles with L7Ae, Nop5, and the methyltransferase fibrillarin into a modification enzyme with unique substrate specificity. Here, we determined the crystal(More)
Fuzzy dominance is a relatively important and new concept for ranking fuzzy variables based on their credibility distributions. As a special case of ordering fuzzy variables, ranking trapezoidal fuzzy variables is a perennial subject of interest because of its foundation in practical application. In the paper, we rank trapezoidal fuzzy variables by(More)
Etiology of Alzheimer's disease (AD) is obscure, but neuroinflammation and accumulation of β-amyloid (Aβ) are implicated in pathogenesis of AD. We have shown anti-inflammatory and neurotrophic properties of obovatol, a biphenolic compound isolated from Magnolia obovata. In this study, we examined the effect of obovatol on cognitive deficits in two separate(More)
Deficits in cognitive functions lead to mental retardation (MR). Understanding the genetic basis of inherited MR has provided insights into the pathogenesis of MR. Fragile X syndrome is one of the most common forms of inherited MR, caused by the loss of functional Fragile X Mental Retardation Protein (FMRP). MicroRNAs (miRNAs) are endogenous,(More)
