Alec Talin is a Senior Scientist in the Chemistry, Combustion and Materials Science Department at Sandia National Laboratories and an Adjunct Associate Professor of Materials Science and Engineering at the University of Maryland, College Park. He is a Fellow of the American Physical Society and a member of Science Board of Reviewing Editors. Prior to joining Sandia in 2002, he spent 6 years as a research scientist and manager at Motorola Labs in Phoenix, AZ, and 3 years (2009-12) as a project leader at the National Institute of Standards and Technology in Gaithersburg, MD. His seminal scientific achievements include first demonstration of high efficiency Si metal-insulator-semiconductor photocathodes with spillover-assisted evolution of hydrogen, first demonstration of guest-induced electronic conductivity in metal-organic frameworks, and first demonstration of tuning of electronic conductivity of metal oxides and polymers through electrochemical ion insertion for achieving high efficiency analog switches for artificial neural networks, a concept now widely referred to as ECRAM.

DnaSP, DNA Sequence Polymorphism, is a software package for the analysis of DNA polymorphisms using data from a single locus (a multiple sequence aligned -MSA data), or from several loci (a Multiple-MSA data, such as formats generated by some assembler RAD-seq software). DnaSP can estimate several measures of DNA sequence variation within and between populations in noncoding, synonymous or nonsynonymous sites, or in various sorts of codon positions), as well as linkage disequilibrium, recombination, gene flow and gene conversion parameters. Moreover, DnaSP can conduct a number of neutrality tests, such as (among other), the Hudson, Kreitman and Aguadé (1987), Tajima (1989), McDonald and Kreitman (1991), Fu and Li (1993), and Fu (1997), Ramos-Onsins and Rozas (2002), Achaz (2009) tests, and compute their confidence intervals by the coalescent. The results of the analyses are displayed on tabular and graphic form.

This is because, indeed, a great part of the artistic production identified as “Mexican” in the post-revolutionary period (1920-1940)1 -which would found the bedrock of the Mexican School of Painting-, consciously adopted Posada as the “prophet of modern Mexican art”-2. This occurred in the midst of a complex panorama, where many interests and agents played, with political, economic, artistic and nationalist ideologies. On the contrary, Posada in life did not have much recognition. At that time, the job of engraver, as illustrator, unlike the “artist engraver” (such as Julio Ruelas, for example), was a worker who was part of the “productive” and daily activities of society, who worked for publishing houses and the dissemina Myocardial infarction is a leading cause of death, since the human heart, like that of most adult mammals, lacks the ability to replace cardiomyocytes (CMs) lost to injury. In contrast, adult zebrafish and a few other highly regenerative animals can repair heart injuries via dedifferentiation and proliferation of spared, mature CMs located at the wound border. Zebrafish CM regeneration is remarkably efficient and complete; in response to cryoinjuries that kill 1/3 of the ventricular CMs, pre-injury CM numbers are restored within 30 days. Many signaling pathways have been found to promote zebrafish CM dedifferentiation and cell cycling. We have previously shown that BMP signaling is required for CM dedifferentiation and proliferation during heart regeneration, but not for CM proliferation during physiological heart growth. This suggests that BMP signaling primarily acts on regeneration-specific cellular processes. Here we show that BMP signaling promotes CM regeneration by alleviation of replication stress. Replication stress and other forms of DNA damage are considered leading causes of declining tissue renewal and repair in aged mammals. Cells experience replication stress when DNA replication forks slow down or stall, due to unresolved DNA lesions like DNA strand breaks, collisions with transcriptional machinery or insufficient nucleotide supplies. Replication stress can arise from the high cell cycling demands imposed by oncogenes or when aged stem cells are challenged to repair a tissue. While cells can use several mechanisms to bypass or tolerate hindrances to replication, unresolved replication stress results in reduced tissue turnover and repair, functional decline of stem cells, cellular senescence, and apoptosis. Here, we find that cycling CMs experience replication stress duri Fig. 1. Diego Rivera, detail from the mural painting Sueño de un paseo dominical en la Aalameda Central. 1947.
