BACKGROUND The identification of novel biomarkers for early breast cancer detection would be a great advance. Because of their role in tumorigenesis and stability in body fluids, microRNAs (miRNAs) are emerging as a promising diagnostic tool. Our aim was to identify miRNAs deregulated in breast tumors and evaluate the potential of circulating miRNAs in(More)
Emerging evidence suggests that BRCA1 pathway contributes to the behavior of sporadic triple negative breast cancer (TNBC), but little is known about the mechanisms underlying this association. Considering the central role that microRNAs (miRNAs) play in gene expression regulation, the aim of this study was to identify miRNAs specifically deregulated in(More)
We conduct a controlled field experiment in 52 communities in rural Bolivia to investigate the effect that local authorities have on voluntary public good provision when they lead by example. In our study, community members pool resources to provide environmental education material for local schools. We find that democratically elected local authorities(More)
Market based mechanisms are proliferating around the globe as a means to offer direct economic incentives for protecting and conserving ecosystem services. Among the ecosystem services being marketed, payments for watershed services (PWS) are the most difficult to establish clear service provision. Most PWS use a land-based compensation method, assuming(More)
INTRODUCTION Prader-Willi syndrome (PWS), a neuroendocrine disorder could be due to: a large paternally derived chromosome deletion of 15q11-13, to maternal uniparental disomy (UPD), or imprinting mutation (IC); amongst this last group five families, with inherited microdeletion encompassing SNRPN were described; in these families excluded a typical large(More)
