rRNAs are extensively modified during their transcription and subsequent maturation in the nucleolus, nucleus and cytoplasm. RNA modifications, which are installed either by snoRNA-guided or by stand-alone enzymes, generally stabilize the structure of the ribosome. However, they also cluster at functionally important sites of the ribosome, such as the peptidyltransferase center and the decoding...

We explore how nuclear modifications to the free nucleon structure functions (also known as shadowing) affect heavy quark production in collisions at different impact parameters. We assume that the nuclear modifications arise from a density dependent effect such as gluon recombination and are thus proportional to the local density. We calculate the dependence of charm and bottom quark productio...

peripheral blood stem cell transplantation (pbsct) is an effective treatment for hematological malignancies. mobilization of peripheral blood progenitor cells performs in different ways among transplantation centers. forceful mobilization schedules are comprised of growth factor alone, chemotherapy along with growth factor and also, a newly combination of novel agent such as plerixafor with any...
