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 ...
