BACKGROUND Agave species can grow well in semi-arid marginal agricultural lands around the world. Selected Agave species are used largely for alcoholic beverage production in Mexico. There are expanding research efforts to use the plentiful residues (bagasse) for ethanol production as the beverage manufacturing process only uses the juice from the central core of mature plants. Here, we investi...

Agave tequilana is an angiosperm species that belongs to the family Asparagaceae (formerly Agavaceae). Even though there is information regarding to some aspects related to the megagametogenesis of A. tequilana, this is the first report describing the complete process of megasporogenesis, megagametogenesis, the early embryo and endosperm development process in detail. The objective of this work...

This essay represents a first attempt to make sense of the mass of early modern English publications that deal with or refer to mathematics, using a bibliometric approach made possible by the new electronic databases: Early English books online and Eighteenth-century collections online. I present statistical information about references to mathematics in this corpus of books, perform some stati...

Pre-Columbian farmers cultivated several species of agave in central Arizona from ca. A.D. 600-1350. Because of the longevity and primarily asexual reproduction of these species, relict agave clones remain in the landscape and provide insights into pre-Columbian agricultural practices. We analyzed variation in allozyme allele frequencies to infer genetic effects of prehistoric cultivation on Ag...

The 20 biannual Meeting of the European Association of Cancer Research EACR-20 was held in Lyon, in July 2008. The Meeting successfully gathered researchers from basic, translational and clinical cancer research to exchange and discuss recent results in the areas of major interest. This review presents a meeting report and intends to be a portrait of the excellent research presented at EACR-20....
