Small RNAs of Opposite Sign… but Same Absolute Value
نویسنده
چکیده
In ciliates, small RNAs have been shown to target foreign sequences for silencing via elimination from the somatic genome. Fang et al. now reveal a set of Piwi-interacting RNAs (piRNAs) in Oxytricha trifallax that likewise enable genomic self versus nonself discrimination, this time by specifying self sequences for genome retention.

Correlation of the Circular Dichroism of Unsubstituted and Ring - Substituted Chiral Phenylcarbinamines with Their Absolute Configurations
The sign of the 1~ Cotton effects (CEs) at about 250-27D nm of the benzene chromophore of unsubstituted chiral phenylcarbinamines and their salts is determined by vibronic borrowing from the lBb-allowed transition at shorter wavelength. For these chiral phenylcarbinamines and their salts of the same generic absolute configuration, the sign of their lLb CEs is the same. On ring substitution, how...
متن کاملTransducer model produces facilitation from opposite-sign flanks
Small spots, lines and Gabor patterns can be easier to detect when they are superimposed upon similar spots, lines and Gabor patterns. Traditionally, such facilitation has been understood to be a consequence of nonlinear contrast transduction. Facilitation has also been reported to arise from non-overlapping patterns with opposite sign. We point out that this result does not preclude the tradit...
متن کاملSex-induced silencing operates during opposite-sex and unisexual reproduction in Cryptococcus neoformans.
Cryptococcus neoformans is a human fungal pathogen that undergoes a dimorphic transition from yeast to hyphae during a-α opposite-sex mating and α-α unisexual reproduction (same-sex mating). Infectious spores are generated during both processes. We previously identified a sex-induced silencing (SIS) pathway in the C. neoformans serotype A var. grubii lineage, in which tandem transgene arrays tr...

متن کاملCUSUM rules for detecting a regime change in the Brownian Motion model with multiple alternatives
This work examines the problem of sequential change detection in the constant drift of a Brownian motion in the case of multiple alternatives. As a performance measure an extended Lorden’s criterion is proposed. When the possible drifts, assumed after the change, have the same sign, the CUSUM rule designed to detect the smallest in absolute value drift, is proven to be the optimum. If the drift...
