The recognition of areas of endemism (AEs) is important for conservation biology and biogeographical regionalization. Our objective was to quantitatively identify AEs and distributional congruence patterns of native rode...

Intra-specific color variation is often underestimated by researchers, and among mammalian species, intra-specific differences in coloration are poorly documented for most species. The main goal of this study was to appl...

BackgroundNitric oxide (NO) is a signalling and physiologically active molecule in animals, plants and bacteria. The specificity of the molecular mechanism(s) involved in transducing the NO signal within and between cell...

In this paper, we demonstrate that circulating antibodies from chronic periodontitis patients reacting with atrial β1-adrenoceptors (β1-ARs) act as an inducer of soluble CD40 ligand (sCD40L) release and prostaglandin E...

Abstract Chimeric antigen receptor (CAR) T cell therapies have achieved clinical success in autologous treatment of hematological malignancies. However, their broader application remains limited. Beyond the biological ch...

The parotid gland participates in the digestive process by providing fluid, electrolytes and enzymes that facilitate the onset of digestion. Neurotransmitters, hormones and biologically active peptides regulate its activ...

Abstract Cardiac tissue from autoimmune myocarditis mice was studied to evaluate the expression and biological activity of mRNA encoding H(1) receptor and iNOS. BALB/c inbred mice were immunized with heart protein and s...

Fine scale patterns of genetic structure and dispersal in Triatoma infestans populations from Argentina was analysed. A total of 314 insects from 22 domestic and peridomestic sites from the locality of San Martín (Capay...

Molecular iodine was identified as an efficient catalyst for the cycloisomerization of conjugated dienals to substituted 2-cyclopentenones. DFT calculations suggested an unexpected concerted character for this cyclizatio...

Two Cu(II) complexes with cyanoguanidine (cnge) and o-phenanthroline, [Cu(o-phen)2(cnge)](NO3)2 · 2H2O (1) and [Cu(o-phen)(cnge)(H2O)(NO3)2] (2), have been synthesized using different experimental techniques and charact...

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...

In this work we study the polytope associated with a 0/1 integer programming formulation for the Equitable Coloring Problem. We find several families of valid inequalities and derive sufficient conditions in order to be ...

Borreria kelleri (Spermacoceae, Rubiaceae), is described as a new species from northeastern Argentina and Paraguay. The new species is morphologically similar to B. quadrifaria due to the presence of densely and notable ...

El sistema de complemento, es un sistema funcional de más de 30 proteínas séricas, que interaccionan entre sí de modo regulado formando una cascada enzimática, permitiendo una amplificación de la respuesta humoral....

Este estudio analiza la incidencia de las estrategias neurosensoriales en el fortalecimiento de la socialización de niños de 3 a 4 años en la Unidad Educativa Fiscomisional San Carlos Lwanga (Guayaquil), durante el pe...

En este artículo reflexionamos sobre la politización de los cuidados comunitarios en contextos urbanos populares, desde la experiencia de Población Juan Antonio Ríos, en Chile. Para ello, se trabajó con la técnica ...

Zinc phthalocyanines have demonstrated a wide range of applications as photosensitisers, particularly in organic synthesis, photocatalysis and photodynamic therapy. Although the introduction of ionic groups on the macroc...

Construir y validar, en el país, una escala para medir violencia hacia las mujeres por parte de la pareja masculina. Asimismo, construir un índice de severidad que permita establecer una dimensión del daño emocional ...

Tendo em perspectiva que o pesquisador que pretende investigar as crianças como sujeitos deve levar em conta quem são as crianças, como participam do processo de produção dos conhecimentos, que significados produzem...

Latin America exhibits one of the highest rates of biodiversity and ecosystem services (ES) loss worldwide along with a remarkable asymmetry in the access to ES benefits (ecosystem services inequality, ESI hereafter). Th...
