Interleukin-10 (IL10) is an immune regulatory cytokine. Single nucleotide polymorphisms (SNPs) in IL10 promoter have been associated with prognosis in adult classical Hodgkin lymphoma (cHL). We analyzed IL10 SNPs −1082...

This article asks to what extent the political mobilization promoted by peasant organizations in Argentina, Chile and Brazil can be inscribed in new forms of “peasant unionization.” Based on a qualitative and ethnogr...

The little known geophilomorph centipede Chilenophilus corralinus (Attems, 1903) (Myriapoda: Chilopoda, Geophilidae), a large geophilid species from South America is herein redescribed and illustrated based on new specim...

Morphology of the shell, radula, jaw, anatomy and sculpture of the inner wall of the reproductive system are described and compared for three species belonging to the Bostryx tortoranus species complex. On the basis of t...

The outbreak of COVID-19, the disease caused by SARS-CoV-2, continues to affect millions of people around the world. The absence of a globally distributed effective treatment makes the exploration of new mechanisms of ac...

Background: Retinoblastoma is a hereditary cancer of childhood caused by mutations in the RB1 tumor suppressor gene. An early diagnosis is critical for survival and eye preservation, thus identification of RB1 mutations ...

We have shown that mice infected with mouse hepatitis virus A59 develop autoantibodies (autoAb) to liver and kidney fumarylacetoacetate hydrolase (FAH). Because it has been proposed that the immune system is stimulated b...

Introduction: Vaccination against foot-and-mouth disease virus is regarded as the most effective way to prevent disease. Selection of appropriate vaccine strains is challenging due to lack of cross-protection between ser...

This paper offers a critique on state formation theories used in the explanation of the rise of the biblical United Monarchy. The last three decades of archaeological and biblical research have shown that there is no fir...

En la Región Oriental del Paraguay se encuentran los humedales del Complejo Ypoá, declarados como sitio RAMSAR y categorizados como Reserva de Recursos Manejados. Pese a estas categorías de protección, su biodiversid...

We report the first results of a shooting experiment performed with lithic point replicas of Fishtailpoints hafted as darts pursuing the aim to estimate the points’ use-lives and related size changesusing survival and ...

Information on the variability of wild bean populations and landraces is essential to set conservation strategies and design breeding programmes aimed at enlarging the genetic base of commercial beans. Nineteen Argentine...

In this review, we highlight the evolution of our knowledge about the way Mg2+ participates in the activation of heterotrimeric G proteins, beginning with its requirement in hormonal stimulation of fat cell adenylyl cycl...

The palynological characterization of 157 honey samples from three northwesternregions of Argentina (Prepuna, Yungas and Chaco) are presented todetermine their botanical origin and species associations to be able to defi...

The interest in transition metal complexes as antitumor agents started in the 1960s with the serendipitous dis- covery of cisplatin. This drug was appr ov ed by the US FDA in the 1970s for its use as a chemotherapeutic a...

There has been much debate surrounding the way in which Ptolemy handled the observations that are behind his planetary models. This article aims at presenting an interesting case of manipulation of observational data wit...

The presence of apoplastic proteins without predicted signal peptide in the gene sequence suggests the existence of protein secretion independent of the ER/Golgi classical route. In animals, one of the pathways proposed ...

Autophagy is a well-conserved process of self-digestion of intracellular components. T. cruzi is a protozoan parasite with a complex life-cycle that involves insect vectors and mammalian hosts. Like other eukaryotic orga...

Chemokine network is central to the innate and adaptive immunity and entails a variety of proteins and membrane receptors that control physiological processes such as wound healing, angiogenesis, embryo growth and develo...

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...

The floral nectary of Bertholletia excelsa was studied through permanent, histological cross-sections. The flower showed two rings of androecial vascular bundles, the inner for the fertile stamens and the outer for the a...

Species limits in the Poospiza nigrorufa/whitii complex are not well understood. Three taxa formally described as species are now considered as subspecies (nigrorufa, whitii and wagneri) of a widespread species. The heav...

Microvertebrates are a major component of many assemblages recovered from the Quaternary of the Argentine Pampas. The main goal of this paper is to analyse the taphonomic history of a Holocene microfossil bonebed, recove...

The lithic assemblages recorded from shell middens along the northern coast of Santa Cruz, Argentine Patagonia, reveal some common trends. In general terms, abundant debris, and a few tools and cores have been identified...
