Uno de los conceptos más divulgados por el Ateneo de la Juventud de México en 1910 fue "La Cultura de las Humanidades", y dos de sus mayores exponentes fueron Pedro Henríquez Ureña y Alfonso Reyes. Este último, just...

El artículo intenta estudiar, tanto en el Poema de Alfonso Onceno como en la Gran Crónica de Alfonso XI, cómo el dispositivo discursivo legendario se utiliza con un fin propagandístico de la figura del rey, pues se d...

El ideal del imperium, contenido en las obras escritas en el scriptorium de Alfonso X, no es meramente un concepto político o militar, sino cultural. Algunos aspectos de este ideal son el conocimiento regio, necesario p...

Al margen de la discusión acerca de la existencia del género "Crónicas rimadas", duda ya apuntada por estudiosos anteriores, nos proponemos demostrar que el Poema de Alfonso Onceno, catalogado por algunos críticos co...

El objetivo de este trabajo es mostrar cómo las variantes discursivas presentes en los diversos prólogos jurídicos de la obra alfonsí, con especial énfasis en Partidas, constituyen elementos particularmente revelado...

The etiology of obesity is multifactorial, and includes genetic, environmental, and dietary factors, where hypercaloric diets play a central role in the development of the disease. It is known that obesity in adulthood c...

I focus on the concept of the receptive field of a sensory neuron, taking it as a prominent case to address conceptual change in the history of neuroscience. I argue for an interpretation of its role and evolution based ...

Density functional theory (DFT) calculations were carried out on hydroxylated and solvated (H&S) Fe substrates. Fe (110) and (111) extended surfaces as well as clusters of 32 and 59 atoms, and a nanoparticle of 80 atoms ...

The knowledge and the ability to describe the phase equilibrium behavior of systems composed of transesterification products are very important in the optimization of biodiesel production and purification process. In thi...

This study address for the first time in Argentina and the South American continent the effect of water management on the presence of microplastics (MPs) in a shallow lake, assessing their contribution to the zooplankton...

En este trabajo se sintetizan resultados parciales de un proyecto de investigación y desarrollo centrado en la generación de tecnologías de inclusión social en territorios de extrema pobreza. Se propone contribuir al...

HOP (HSP70-HSP90 organising protein) is a conserved family of co-chaperones well known in mammals for its role in the folding of signalling proteins associated with development. In plants, HOP proteins have been involved...

Phosphorylated non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase (EC 1.2.1.9; GAPN) found in heterotrophic cells of wheat is activated by MgCl2. The divalent cation disrupts the interaction between GAPN and a ...

We assessed the influence of environmental factors in shaping the free-living bacterial community structure in a set of shallow lakes characterized by contrasting stable state patterns (clear-vegetated, inorganic-turbid ...

This study assesses for the first time the relationship between annual cycles of different biological indices with growth patterns of a marine pejerrey Odontesthes argentinensis population near its southern-distribution ...

The pejerrey, Odontesthes bonariensis, is being considered for aquaculture due to its high demand and market price. Reproduction and larviculture studies have demonstrated the feasibility of massive fingerling production...

M6a is a neuronal membrane glycoprotein whose expression diminishes during chronic stress. M6a overexpression in rat primary hippocampal neurons induces the formation of filopodial protrusions that could be spine precurs...

AbstractA simple, rapid and reliable procedure for permeabilizing cyanobacterial cells and measuring the glycogen synthetic pathway in situ, is presented. Cells from Anabaena sp. strain PCC 7120 were permeabilized with a...

With the advancement of personalized cancer immunotherapies, new tools are needed to identify tumor antigens and evaluate T-cell responses in model systems, specifically those that exhibit clinically relevant tumor progr...

Nonphosphorylating glyceraldehyde-3-phosphate dehydrogenase (np-Ga3PDHase) is a cytosolic unconventional glycolytic enzyme of plant cells regulated by phosphorylation in heterotrophic tissues. After interaction with 14-3...

El presente trabajo analiza los procesos de organización eclesiástica que tuvieron lugar en las villas nuevas reales de la diócesis de León a partir de la repoblación llevada a cabo en las últimas décadas del sigl...

The mechanisms behind phytoplankton diversity patterns in natural ecosystems still remain elusive. In two shallow lakes with contrasting river connectivity, we first explored how diversity within each sampling (alfa dive...

Gymnopilus pampeanus (GP) is a mushroom consumed in Argentina. Spent Populus sawdust (SPS) obtained from the cultivation of GP was used to test methane production. The effect of two substrate/inoculums (S/I) ratios was a...

We report a novel nanosecond laser ablation synthesis for spherical gold nanoparticles as small as 4 nm in only 5 s (532 nm, 0.66 J/cm 2), where the desired protecting agent can be selected in a protocol that avoids repe...
