El siglo XVI americano fue escenario de la lucha de partidos entre los españoles que defendieron con vigorosa fidelidad a sus respectivos líderes. En la Conquista del Perú se encuentra el caso que mejor demuestra el nivel de violencia que alcanzaron las rivalidades partidarias. Fue en la singular, difícil y posteriormente violenta relación entre Diego de Almagro y Francisco Pizarro desde la salida de Panamá en 1524 hasta la lucha por la dominación de la ciudad del Cuzco en 1538.

Although many immigrants enter the United States with a healthy body weight, this health advantage disappears the longer they reside in the United States. To better understand the complexities of obesity change within a cultural framework, a community-based participatory research (CBPR) approach, PhotoVoice, was used, focusing on physical activity among Muslim Somali women. The CBPR partnership was formed to identify barriers and resources to engaging in physical activity with goals of advocacy and program development. Muslim Somali women (n = 8) were recruited to participate, trained and provided cameras, and engaged in group discussions about the scenes they photographed. Participants identified several barriers, including safety concerns, minimal culturally appropriate resources, and financial constraints. Strengths included public resources and a community support system. The CBPR process identified opportunities and challenges to collaboration and dissemination processes. The findings laid the framework for subsequent program development and community engagement.

Resumen: El presente trabajo es un análisis individual de cada Oración Patriótica enunciada en el título. En cada una de ellas se destaca, como eje de estudio, el lenguaje utilizado y el orden dialéctico que cada personaje propone. El tiempo histórico en que cada uno de los discursos fue pronunciado es también analizado como relación directa a la naturaleza del mensaje. Se busca remarcar además la preeminencia que tuvo el clero criollo como uno de los actores sociales fundamentales del proceso revolucionario.

Resumen: El anarquismo encontró en el internacionalismo un elemento esencial para la unión del movimiento libertario, pues consideraba que una alianza universal se lograría sólo atravesando las fronteras. Fueron numerosos los pensadores ácratas que buscaron cumplir este objetivo y que, desde su papel de teóricos-militantes, no sólo contribuyeron a la conformación del universo intelectual anarquista en Buenos Aires en las primeras décadas del siglo XX sino que, a través de su rol de agentes activos en el proceso de gestación, recepción y circulación de ideas, intentaron relacionar el anarquismo local con el latinoamericano y el europeo. Dentro de este grupo se destacó, entre los años 1920 y 1930, Diego Abad de Santillán quien, tanto en su papel de teórico como de militante, periodista, escritor, editor y traductor, constituyó una pieza fundamental para el engranaje intelectual libertario desplegado entre Europa y América Latina, e integró el conjunto de pensadores que lideraron el anarquismo argentino. Al cruzar ambos movimientos, no sólo actuó como nexo sino que también buscó representar, y dar respuestas, a los múltiples y variados intereses de la clase trabajadora.

Phosphoglucose isomerase (PGI) catalyzes the reversible isomerization of glucose-6-phosphate and fructose-6-phosphate. It is involved in glycolysis and in the regeneration of glucose-6-P molecules in the oxidative pentose phosphate pathway (OPPP). In chloroplasts of illuminated mesophyll cells PGI also connects the Calvin-Benson cycle with the starch biosynthetic pathway. In this work we isolated pgi1-3, a mutant totally lacking pPGI activity as a consequence of aberrant intron splicing of the pPGI encoding gene, PGI1. Starch content in pgi1-3 source leaves was ca. 10-15% of that of wild type (WT) leaves, which was similar to that of leaves of pgi1-2, a T-DNA insertion pPGI null mutant. Starch deficiency of pgi1 leaves could be reverted by the introduction of a sex1 null mutation impeding beta-amylolytic starch breakdown. Although previous studies showed that starch granules of pgi1-2 leaves are restricted to both bundle sheath cells adjacent to the mesophyll and stomata guard cells, microscopy analyses carried out in this work revealed the presence of starch granules in the chloroplasts of pgi1-2 and pgi1-3 mesophyll cells. RT-PCR analyses showed high expression levels of plastidic and extra-plastidic beta-amylase encoding genes in pgi1 leaves, which was accompanied by increased beta-amylase activity. Both pgi1-2 and pgi1-3 mutants displayed slow growth and reduced photosynthetic capacity phenotypes even under continuous light conditions. Metabolic analyses revealed that the adenylate energy charge and the NAD(P) H/NAD(P) ratios in pgi1 leaves were lower than those of WT leaves. These analyses also revealed that the content of plastidic 2-C-methyl-D-erythritol 4-phosphate (MEP)-pathway derived cytokinins (CKs) in pgi1 leaves were exceedingly lower than in WT leaves. Noteworthy, exogenous application of CKs largely reverted the low starch content phenotype of pgi1 leaves. The overall data show that pPGI is an important determinant of photosynthesis, energy status, growth and starch accumulation in mesophyll cells likely as a consequence of its involvement in the production of OPPP/glycolysis intermediates necessary for the synthesis of plastidic MEP-pathway derived hormones such as CKs.

Between 1889 and 1916, the U. S. Fish Commission steamer Albatross made numerous trips to waters off southern California, particularly in and near San Diego Bay. The typical pattern for many years was to conduct cruises in waters off the Pacific Northwest or Alaska in summer months and waters off southern California in winter months. The Albatross conducted the first depth soundings and benthic profiles for southern California waters and secured the first samples of many endemic marine animals of this region. Albatross collections formed the basis for numerous definitive monographs of invertebrates and vertebrates that were published in subsequent years. The Albatross anchored in San Diego Bay in 1894, conducting the first biological investigations of the bay, and returned to sample again in many subsequent years. The ship and its crew also examined Cortez and Tanner banks for exploitation potential and conducted the first biological investigations of southern California’s tuna stocks in 1915 and 1916.

A través de esta serie intentaremos conocer diferentes facetas personales de los integrantes de nuestra “comunidad”. El cuestionario, además de su principal objetivo, con sus respuestas quizás nos ayude a encontrar entre nosotros puntos en común que vayan más allá de nuestros temas de trabajo y sea un aporte a futuros estudios históricos. Esperamos que esta iniciativa pueda ser otro nexo entre los ictiólogos de la región, ya que consideramos que el resultado general trascendería nuestras fronteras.
