Resumo Este artigo aborda os projetos de país desenhados por dois autores/atores entre o final do século XIX e as décadas iniciais do século XX: Rui Barbosa, expoente do pensamento liberal; e Alberto Torres, reconhec...

Objective: To provide information on the secular trend in age at menarche (AgM) in Argentinean girls in relation to excess weight (EW) and body adiposity.Methods: Two cohorts (C) (C1, 2005-2007 and C2, 2015-2019) of chil...

The aim of this study was to combine high hydrostatic pressure (HHP) and SFE-CO2 to extract bioactive compounds with antioxidant capacity (phenolics and β-carotene) from Cape gooseberry (Physalis peruviana L.) pulp. Ext...

The Fuegian thrust-fold belt (TFB) forms the thin-skinned outer wedge of the Andes in Tierra del Fuego. Using subsurface and outcrop data from two areas (Western and Eastern) of the TFB front in Argentina we aimed to ver...

The study of olive (Olea europea L.) genetic variability is important for the design of plant breeding programs. In Argentina, as in other regions of the world, there are local genetic materials with high agronomic value...

This study examines the fast pyrolysis of rosehip seed waste (RSW) in a fluidized bed reactor, evaluating its potential for syngas production and effective waste valorization. The fluidization behavior of sand/RSW mixtur...

The Chacoan peccary Catagonus wagneri is the rarest and most threatened of the three extant species of peccary. Its presence has been recorded in the northern Dry Chaco ecoregion, which spans northern Argentina, western ...

Phosphoenolpyruvate carboxykinase (PEPCK) catalyses the reversible reaction of decarboxylation and phosphorylation of oxaloacetate (OAA) to generate phosphoenolpyruvate (PEP) and CO2 playing mainly a gluconeogenic role i...

Dados de 36.755 primeiras lactações de vacas holandesas, filhas de 866 reprodutores, distribuídas em diferentes estados no período de 1980 a 1993, foram estratificados em rebanhos de acordo com o desvio-padrão fenot...

The fossils of the India Muerta Formation (Neogene, Tucumán Province, Northwestern Argentina) include several vertebrate groups, mainly metatherian, xenarthran, and notoungulate mammals. Nevertheless, these remains have...

Trypanosoma cruzi, the etiological agent of Chagas disease, has a digenetic life cycle. In itspassage from the insect vector to the mammalian host, and vice versa, it must be preparedto cope with abrupt changes in enviro...

Four members of the potato (Solanum tuberosum L.) calcium-dependent protein kinase (CDPK) family StCDPK22/23/24 and StCDPK27, present three functional EF-hands motifs in their calmodulin-like domain (CLD). StCDPK22/23/24...

Background: Mutations in the glucocerebrosidase (GBA) gene represent the most common genetic risk factor for Parkinson's Disease (PD) and are associated with a more aggressive motor phenotype at late stages. However, the...

St. Louis encephalitis virus (SLEV) is endemic in the Americas and its transmission networks involve Culex mosquitoes and avian species. In 2015, a human encephalitis outbreak took place in Arizona and California, indica...

We describe the functional properties of a nicotinic alpha9/serotonin subtype 3A (5HT3A) chimeric receptor expressed in Xenopus laevis oocytes. The chimera preserved ligand-binding properties of alpha9 and channel proper...

The organ of Corti, the auditory mammalian sensory epithelium, contains two types of mechanotransducer cells, inner and outer hair cells (IHCs and OHCs, respectively). IHCs are involved in conveying acoustic stimuli to t...

Electromagnetic driving in a honeycomb lattice can induce gaps and topological edge states with a structure of increasing complexity as the frequency of the driving lowers. While the high frequency case is the most simpl...

Intracellular levels of cyclic nucleotide second messengers are regulated predominantly by a large superfamily of phosphodiesterases (PDEs). Most of the different PDE variants play specific physiological functions; in fa...

Plant irritability for light stimuli becomes crucial to cope with ambient fluctuations in order to keep up homeostasis and accomplish the life cyclesuccessfully. Light environment governs plant development. Perception of...

The hair cells of the vertebrate inner ear posses an active mechanical process to amplify their inputs. The stereocilia bundle of various vertebrate animals can produce active movements. Though standard stereocilia-based...

Seedsnipes (family Thinocoridae, genera Attagis and Thinocorus with two species each) are strictly vegetarian shorebirds occurring in some of the coldest and driest habitats of southern South America. It has been hypothe...

In order to clarify the physiological role of ghrelin in gestation, we evaluated the effects of administration of exogenous ghrelin (2 or 4 nmol/animal per day) or its antagonist (6 nmol/animal per day of (D-Lys3)GHRP6) ...
