El bicarbonato (HCO3-) es el producto de desecho de la respiración mitocondrial. Las proteínas transportadoras de HCO3- (TB) facilitan el movimiento del HCO3- para acelerar el descarte de CO2, controlar el pH celular y...

Sterol regulatory element binding proteins (SREBP), encoded by the Srebf1 and Srebf2 genes, are important regulators of genes involved in cholesterol and fatty acid metabolism. Whereas SREBP-2 controls the cholesterol sy...

Aims. Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies and potentially enhance nuclear activity. However, the extent to which bars influence active galactic nuclei (A...

Desde diversas fuentes orales analizamos la conformación de dos colectivos obreros, construidos a partir de la implantación de polos de desarrollo en la Patagonia argentina y la Amazonia brasileña. Estos proyectos tra...

Este trabajo analiza el tratamiento de la emergencia en el sistema jurídico desde la perspectiva de la conjetura planteada por Henri Poincaré en el ámbito de la topología en 1904. Una conjetura que fue resuelta final...

La convivencia escolar constituye hoy en día un eje fundamental de reflexión en el ámbito de las Ciencias de la Educación, al tiempo que representa una preocupación prioritaria para los centros escolares y un criter...

Se presentan los resultados del trabajo realizado en la Estación Meteorológica de CARSUCRE, en bosque seco tropical del municipio de Colosó, departamento de Sucre (Colombia), donde se efectuaron transectos lineales de...

Coral reef systems on the southeastern Cuban shelf are exposed to rapid warming and increasingly frequent marine heatwaves (MHWs). However, the physical drivers of local sea-surface temperature (SST) variability remain...

Constitui-se o presente trabalho da transcrição integral da palestra realizada pelo Dr. Harald Sioli (1910-2004) no Seminário da Amazônia, em 10 de agosto de 1990, quando numa última viagem ao Amazonas, ao completar...

Fe–Mn based alloys with more 12% at. of Mn are usually called High-Mn steels. Several technological properties of High-Mn steels are explained by the presence of the fcc-hcp martensitic transformation. This transition ...

We present data about the synthesis of urea from different substrates, i.e., free ammonia, glutamine and alanine in primary cultured rat hepatocytes treated or untreated with the model hepatotoxic agent thioacetamide (TA...

Extracellular nucleotides and nucleosides activate signaling pathways that play major roles in the physiology and pathophysiology of the gastrointestinal tract. Ectonucleotidases hydrolyze extracellular nucleotides and t...

Commerson’s dolphins (Cephalorhynchus commersonii) are separated into the subspecies C. c. commersonii, found along southern South America (SA) and the Falkland Islands/Islas Malvinas (FI/IM), and C. c. kerguelenensis,...

Most alpine ecosystems are subject to non-native species invasion as climate warms and human disturbance increases. Therefore, it is important to identify the main barriers and facilitators of alpine plant invasions. Whi...

A green and sustainable approach to the direct synthesis ofthioesters has been developed using Fe3O4 as a low-cost, easilyprepared, reusable and environmentally safe catalyst. The crossdehydrogenative coupling (CDC) of v...

Trade-offs between yield and grain quality for dry milling are common in maize (Zea mays L.), but the magnitude of these correlations can differ depending on the specific quality trait. We aimed to quantify the relations...

Soy protein isolate (SPI) films reinforced with starch nanocrystals (SNC) were developed by simple casting method. The films were transparent and homogeneous. The opacity and degree of crystallinity increased with the am...

A new series of heterofused thiazolo/pyrazinedione hybridswere designed, synthetized and their cytotoxicity potential wasevaluated against different cancer cell lines. Besides, druglikenessand in silico ADME/Tox studies ...

En el marco de una investigación dedicada al campo literario argentino de 1969, se examinan episodios vinculados a la circulación de la literatura chilena en Buenos Aires. En particular, el artículo se detiene en una ...

El objetivo de este trabajo es realizar una re-evaluación de un PSA desarrollado en la ciudad de Salta, Argentina, con enfoque específico en el análisis de las medidas de control y el cálculo de los riesgos en el per...

Various systematic approaches have been applied to the Neogene planicostate carditids of Patagonia. Some authors have included these species within Venericor (known from the Eocene of North America and Europe) or in Mega...

The dataset of free-living soil nematodes from Colección Helmintológica of Museo de La Plata is presented. There is a large knowledge gap regarding soil nematodes especially in Argentina but also in the Neotropical reg...

Results on stress analysis for single-crystal diamonds are presented. Isolated crystals were studied by Raman mapping and depth profiling techniques, using confocal microscopy. Diamonds were deposited on molybdenum and t...
