Dicer controls the biogenesis of microRNAs (miRNAs) and is essential for neurogenesis. Recent reports show that the levels and substrate selectivity of DICER result in the preferential biogenesis of specific miRNAs in vitro. However, how dicer expression levels and miRNA biogenesis are regulated in vivo and how this affects neurogenesis is incompletely(More)
A large number of microRNAs (miRNAs) are grouped into families derived from the same phylogenetic ancestors. miRNAs within a family often share the same physiological functions despite differences in their primary sequences, secondary structures, or chromosomal locations. Consequently, the generation of animal models to analyze the activity of miRNA(More)
We present the results of a survey of the analogs of weak Mgii absorbers (rest– frame equivalent width W r (2796) < 0.3 ˚ A) at 0 < z < 0.3. Our sample consisted of 25 HST/STIS echelle quasar spectra (R = 45, 000) which covered Siii 1260 and Cii 1335 over this redshift range. Using those similar transitions as tracers of Mg ii facilitates a much larger(More)
1 Introduction Despite much interestin the areaof Scientific Database Systems [2, 11], a major problem that many experimental scientists are still facing today is that there are no adequate experiment management tools that are powerful enough to capture the complexity of the experiments and at the same time are natural and intuitive to the non-expert. Over(More)
