The construction of a network capturing the topological structure linked to the interactions among species and the analysis of its properties constitutes a clarifying way to understand the functioning of an ecosystem at ...

The effects of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) - widely used in the world and mainly excreted by the renal route in exposed humans - were studied on the virulence and surface characteristics of an ur...

Current hypotheses of early tetrapod evolution posit close ecological andbiogeographic ties to the extensive coal-producing wetlands of the Carboniferouspalaeoequator with rapid replacement of archaic tetrapod groups by ...

Daily morphological variations have been previously described in the viscacha (Lagostomus maximus maximus) retina. The aim of this work was to determine the effects of lithium administration on the histology of retinas f...

When polymers are irradiated with heavy ions new chemical groups are created in a few microns of the material. The irradiation changed the polarity and wettability on the surface so that could enhance the biocompatibilit...

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...

Robust Data Reconciliation strategies provide unbiasedvariable estimates in the presence of a moderate quantity of measurement grosserrors. Systematic errors which persist in time, as biases or drifts, overcome thisquant...

Relative changes in geomagnetic field intensity over the last 16,000 years BP were recovered from the study of four cores obtained from Lake Escondido (South Argentina). Rock magnetic analysis shows that the main magneti...

One of the largest silicic igneous provinces of the world, the Chon Aike Volcanic Province, is related to an extensional regime developed in Patagonia in Early to Middle Jurassic times. This work presents new geochemical...

Introducción: La primera Área Marina Protegida de mar abierto (no costera) en Argentina, llamada “Namuncurá I” (AMPN), fue creada en 2013 en el Banco Burdwood (BB), una plataforma sumergida ubicada unos 200 km al ...

Dengue virus RNA-dependent RNA polymerase specifically binds to the viral genome by interacting with a promoter element known as stem-loop A (SLA). Although a great deal has been learned in recent years about the functio...

The western coast of South America is one of the most seismogenic zones of the world, due to the subduction of the oceanic Nazca Plate below South America. The spatial distribution of large-magnitude earthquakes or of th...

Jürgen Habermas obchodził w 2019 roku 90. urodziny. Wykorzystaliśmy tę rocznicę jako okazję, aby porozmawiać z jednym z najbardziej wpływowych współczesnych intelektualistów o aktualnych wydarzeniach społeczn...

In this survey, the notion of a balanced best multipoint local approximation is fully exposed since they were treated in the Lp spaces and recent results in Orlicz spaces. The notion of balanced point, which was introduc...

Los estudios neotafonómicos de vertebrados proveen información sobre los mecanismos y procesos que pueden modificar las características originales de los elementos esqueléticos de vertebrados actuales, y pueden usars...

Metabolic syndrome (MetS) is defined by the concurrence of different metabolic conditions: obesity, hypertension, dyslipidemia, and hyperglycemia. Its incidence has been increasingly rising over the past decades and has ...

Trichomycetes, mainly from nonbiting midge (Chironomidae), mosquito (Culicidae) and black fly (Simuliidae) larvae (Insecta: Diptera), are reported from diverse freshwater environments principally from previously unexplor...

Palbociclib (PALBO), a CDK 4/6 inhibitor, is currently used in combination with endocrine therapy targeting estrogen receptors to treat advanced luminal breast cancer. However, with time tumors become resistant to these ...

The pattern of somatic growth reflects the variable allocation of energy and materials throughout ontogeny, with direct impact on an individual’s fitness, and is therefore expected to be adaptive with regard to the dif...

Ceratium furcoides is an invasive freshwater dinoflagellate that in the last three decades has expanded its geographic distribution in South America, being recently found in Paraná River floodplain (Argentina). Despite ...

The probiotic Gram-positive bacterium Lactobacillus casei BL23 is naturally confronted with salt- stress habitats. It has been previously reported that growth in high-salt medium, containing 0.8 M NaCl, leads to modifica...

Silicon dioxide (SiO2), a material known as “silica” presents properties that make it a good candidate as a biomaterial: it has a very labile surface for functionalization, it is easy to synthesize and it is biocompa...
