Terminal differentiation of muscle cells results in opposite effects on gene promoters: muscle-specific promoters, which are repressed during active proliferation of myoblasts, are turned on, whereas at least some proliferation-associated promoters, such as c-fos, which are active during cell division, are turned off. MyoD and myogenin, transcription factors from the basic-helix-loop-helix (bHL...

We propose to measure multiplicities and longitudinal double spin asymmetries for pions (π, π−, π) and kaons (K, K−, K s ) in Semi-Inclusive Deep Inelastic Scattering (SIDIS) from hydrogen and deuterium. The data will be used to extract the individual contributions of quarks and anti-quarks to the nucleon spin, in addition to measuring the x-dependence of the strange parton distribution functio...

The avian basilar papilla is composed of hair and supporting cells arranged in a regular pattern in which the hair cells are surrounded and isolated from each other by supporting cell processes. This arrangement of cells, in which the apical borders of hair cells do not contact one another, may be generated by contact-mediated lateral inhibition. Little is known, however, about the way in which...

The following are highlights from the series, Circulation: Cardiovascular Interventions Topic Review. This series summarizes the most important manuscripts, as selected by the editors, which have published in the Circulation portfolio. The studies included in this article represent the most noteworthy research in the areas of transcatheter aortic valve replacement and transcatheter aortic-valve...

I analyze an extension of the New Keynesian model that features overlapping generations finitely lived agents and (stochastic) transitions to inactivity. In contrast with standard model, proposed framework allows for existence rational expectations equilibria asset price bubbles. study conditions under which bubble-driven fluctuations may emerge type monetary policy rules prevent them. conclude...

18 An outbreak of human botulism was due to consumption of ham containing botulinum 19 neurotoxins B and E. Clostridium botulinum type E strain isolated from ham was assigned to 20 a new subtype (E12) based on bont/E gene sequencing and belongs to a new multi locus 21 sequence subtype as analyzed by whole genome sequencing. 22
