This paper provides empirical evidence of the long-and short-term eects of exposure to political violence on human capital accumulation. Using a novel data set that registers all the violent acts and fatalities during the Peruvian civil conict, I exploit the variation in conict location and birth cohorts to identify the eect of the civil war on educational(More)
The interactions between stem cells and extracellular matrix (ECM) mediated by integrins play important roles in the processes that determine stem cell fate. However, the role of ECM/integrin interaction in the formation of embryoid bodies (EBs) during cardiogenesis from murine induced pluripotent stem cells (miPSCs) remains unclear. In the present study,(More)
BACKGROUND Embryonic Stem Cells (ESCs) can differentiate into cardiomyocytes (CMs) in vitro but the differentiation level from ESCs is low. Here we describe a simple co-culture model by commercially available Millicell™ hanging cell culture inserts to control the long-term differentiation of ESCs into CMs. METHODOLOGY/PRINCIPAL FINDINGS Mouse ESCs were(More)
Environmental factors are important for stem cell lineage specification, and increasing evidence indicates that the nanoscale geometry/topography of the extracellular matrix (ECM) directs stem cell fate. Recently, many three-dimensional (3D) biomimetic nanofibrous scaffolds resembling many characteristics of the native ECM have been used in stem cell-based(More)

We identify critical stocks-to-use ratios (SURs) for major grains and for an index of total calories from these grains. The latter appears to be a promising indicator of vulnerability to large price spikes when the current price shows no cause for concern. More generally, our results suggest that stocks data, though no doubt unreliable, can be valuable(More)
We previously reported that the pluripotent stem cells can differentiate into cardiomyocytes (CMs) by co-culture with neonatal CMs (NCMs) in vitro. However, the involving mechanism is not clear. Mouse induced pluripotent stem cells (iPSCs) were cultured in hanging drops to form embryoid bodies (EBs) and to induce myocardial differentiation. Co-culture of(More)
