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...

Purpose: To compare the results obtained for tumour control probability (TCP) in protracted treatments, we used two models which apply Poisson statistics for clonogenic cell distribution and a non-Poissonian model, empha...

Objective: The following pilot mixed-design study evaluate a novel intervention feasibility and acceptability to generate preliminary hypotheses considering its potential to promote responsible screen and book use, paren...

Desde 2004 implementamos una investigación colaborativa basada en talleres participativos, para indagar acerca de la construcción de una cooperativa de recicladoras/es y la organización de su proceso de trabajo. Acomp...

In fungal biocontrol strategies, the interaction between phytopathogenic and antagonistic fungi elicits diverse phenotypic and metabolic responses, influenced by the fungal isolates and culture conditions. This study aim...

In the past years, extracellular vesicles (EVs) have become an important field of research since EVs have been found to play a central role in biological processes. In pathogens, EVs are involved in several events during...

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...

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 ...

Mansonella ozzardi (Nematoda: Onchocercidae) is an understudied filarial nematode, originally described by Patrick Manson in 1897, that can be transmitted by two families of dipteran vectors, biting midges (most of them ...

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...

Hydrogen is widely considered a promising green energy vector. It may be produced by steam reforming of methane which may be obtained from renewable resources such as biogas or biomass gasification. Nickel catalysts supp...

Various systematic approaches have been applied to the Neogene planicostate carditids of Patagonia. Some authors have included these species within Venericor (known from the Eocene of North America and Europe) or in Mega...

We studied individual traits related with sexual reproduction of Lychnorhiza lucerna and review how sexual maturation has been studied for scyphomedusae, focusing on the particular case of non-brooding species. L. lucern...

The clam Neilonella sulculata is the dominant bivalve on muddy bottoms along the Argentine continental shelf (Southwest Atlantic). The medusa stage of the hydroid Bougainvillia macloviana is one of the most abundant spec...

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 ...

Tayassu pecari is widely distributed across the Neotropical region, from northern Argentina to south-eastern Mexico. However, its fossil record is scarce; it is recorded since the middle Pleistocene to Holocene in Argent...

New species of Cryptaulax and Procerithium (Procerithiidae, Caenogastropoda) are reported from the Lower Jurassic (Pliensbachian-Toarcian) marine deposits of west-central Chubut province, Argentinean Patagonia. Three new...

Objective: Both good therapeutic bond as well as extra-therapeutic social support seem to enhance treatment outcomes. Some features of the therapeutic bond are similar to experiences in extra-therapeutic relationships (e...

The Upper Miocene-Lower Pliocene Río Negro Formation (Río Negro Province, Argentina) contains diverse and abundant continental trace fossils. The purpose of this contribution is to recognize distinctive trace fossil as...

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...

Abstract The trajectory tracking control problem is addressed for autonomous underwater vehicle (AUV) in marine environment, with presence of the influence of the uncertain factors including ocean current disturbance, dy...

Abstract A numerical control (NC) tool path of digital CAD model is widely generated as a set of short line segments in machining. However, there are three shortcomings in the linear tool path, such as discontinuities of...
