Esta produção tem o intuito de apresentar fotografias e textos, resultados de uma proposta de investigação sobre o ambiente e o cotidiano de idosos ribeirinhos amazônicos. Traz, na sua composição, elementos cultur...

The tropical tree Schizolobium amazonicum is native from the Amazonian forest, naturally occurring in Brazil, Peru and Colombia. This work aimed to study the veneer yield made from this species. For this purpose, 50 logs...

We use cosmological hydrodynamical simulations including star formation and metal enrichment to study the evolution of the chemical properties of galaxy-like objects at high redshift in the range 0.25 < z < 2.35 in a hie...

Interest in time-resolved connectivity in fMRI has grown rapidly in recent years. The most widely used technique for studying connectivity changes over time utilizes a sliding windows approach. There has been some debate...

Background: Copper (Cu) is an essential trace metal used as a catalytic cofactor for many enzymes. However, it can have nocive effects when it participates in the Fenton reaction, producing reactive oxygen species (ROS)....

The article shows dataset of the proteolysis of a natural variant of apolipoprotein A-I (apoA-I) with a substitution of a leucine by and arginine in position 60 (L60R), in comparison with the protein with the native sequ...

El artículo se propone reconstruir las reconfiguraciones que sufrió el periodismo político entre las décadas de 1960 y 1970, enfocándose en los roles del oficio y en los modelos de periodismo que se volvieron legít...

A positive relationship between protein concentration and yield has been documented in different combinations of genotype and environment, often under potential conditions. However, the ecophysiological bases underlying ...

Context. Meditation incorporation helps to fight against disorders such as depression, stress, and anxiety. Specifically, few studies have studied Osho's Active Meditation on young people, but observed evidence using pas...

Perinatal asphyxia (PA) remains as one of the most important causes of short-term mortality, psychiatric and neurological disorders in children, without an effective treatment. In previous studies we have observed that t...

El presente trabajo propone a partir de una serie de intervenciones en el campo de la teoría una cartografía de propuestas artísticas desde una flexión biopolítica considerando la elaboración de imágenes críticas...

The aim of this study is to investigate the folding reaction of human frataxin, whose deficiency causes the neurodegenerative disease Friedreich’s Ataxia (FRDA). The characterization of different conformational states ...

Physical dormancy enables plants that occur in temporally stochastic and harsh environments to survive; thus, within the distribution area of a species, the percentage of seeds with physical dormancy is expected to incre...

The hydatid disease parasite Echinococcus granulosus has a restricted lipid metabolism, and needs to harvest essential lipids from the host. Antigen B (EgAgB), an abundant lipoprotein of the larval stage (hydatid cyst), ...

La historia del género testimonial en la Argentina, cuyos orígenes se vinculan a la politización del campo cultural iniciada en la segunda mitad de la década de 1950, plantea una tarea aún pendiente para la crítica...

There is a growing interest in the potential of mesenchymal stem cells (MSCs) for implementing regenerative medicine in the brain as they have shown neurogenic and immunomodulatory activities. We assessed the effect of i...

This work presents an experimental study of the response of a liquid bridge formed between a sphere and a plane solid surface subjected to a vertical sinusoidal vibration. The amplitude and frequency of the oscillations ...

Advanced prostate cancer (PCa) represents the fifth cause of cancer death worldwide. Although survival has improved with second-generation androgen signaling and Parp inhibitors, the benefits are not long-lasting, and ne...

An on-line inorganic (InHg) and organomercury (OrHg) species separation, preconcentration and determination system consisting of cold vapor atomic absorption spectrometry (CV-AAS) coupled to a flow injection (FI) method ...

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...

Background and aims: The transition of macrophage to foam cells is a major hallmark of early stage atherosclerotic lesions. This process is characterized by the accumulation of large cytoplasmic lipid droplets containing...

Este trabajo se encuadra dentro de un proyecto general orientado al análisis del aprovechamiento de los ambientes fluviales por parte de los grupos cazadores-recolectores en el Holoceno tardío. El área de trabajo eleg...
