El Rol de las Plantas Exóticas en la Homogeneización y Diferenciación Florística en Argentina
(Universidad de Ciencias Empresariales y Sociales, 2016-12)
La aparición de especies exóticas puede afectar la similitud biótica al comparar diversas áreas entre sí. A fin de analizar procesos de homogeneización y diferenciación florística en áreas de distintas ecorregiones argentinas, ...
A comparison of heterochromatic regions in three species ofneotropical canids
(Elsevier Gmbh, 2014-07)
Repetitive DNA varies in nature and abundance, and has had an important role in genome evolution of higher eukaryotes. In the present study we analyzed the dynamics of heterochromatic regions and telomeric sequences in ...
Analysis of the pX region of bovine leukemia virus in different clinical stages of Enzootic Bovine Leukemia in Argentine Holstein cattle
(Elsevier Science, 2013-01)
Bovine leukemia virus (BLV) infection in cattle causes Enzootic Bovine Leukemia (EBL). About 30% of infected cattle develop persistent lymphocytosis (PL), a 0.1–5% develops tumors, and a 70% remains asymptomatic in an ...
Epigeal arthropod communities in intensively farmed landscapes: effects of land use mosaics, neighbourhood heterogeneity, and field position
(Elsevier, 2014-05-10)
Trophic guilds of epigeal arthropods regulating insect pest populations may be affected by factors act-ing across spatial scales. Although the influence of landscape factors associated with farming effects onarthropod ...
Halogen bonding in biological context: a computational study of D2 dopamine receptor
(John Wiley & Sons Ltd, 2016-11)
In this work, Halogen Bond (X-bond) interactions formed by halogenated ligands (LX) at the Dopamine Receptor D2 (DRD2) binding pocket were studied by Molecular Dynamics (MD) and charge density analysis. The X-bonds were ...
Redescription of Hypoptopoma inexpectata, with notes on its anatomy (Siluriformes: Loricariidae)
(Asociación Argentina de Ciencias Naturales, 2000-03)
Se presenta una diagnosis y redescripción de Hypoptopoma inexspectata sobre la base del examen de material adicional y comparación con sus congéneres. Esta especie de Hypoptopoma, pobremente conocida, se distribuye en las ...
FIDEL—a retrovirus-like retrotransposon and its distinct evolutionary histories in the A- and B-genome components of cultivated peanut
(Springer, 2010-02-02)
In this paper, we describe a Ty3-gypsy retrotransposon from allotetraploid peanut (Arachis hypogaea) and its putative diploid ancestors Arachis duranensis (A-genome) and Arachis ipaënsis (Bgenome). The consensus sequence ...
Studies on electrostatic interactions within model nano-confined aqueous environments of different chemical nature
(Springer, 2017-09)
We study the potential of mean force for pairs of parallel flat surfaces with attractive electrostatic interactions by employing model systems functionalized with different charged, hydrophobic and hydrophilic groups.We ...

Drug Consumption in the Masculine School Population Using the Peer Methodology and the Standard Self Assessment Questionnaire
(2011)
The objective of this study is to compare the declared licit and illicit drug consumption, between paired methodology (MP) and self assessed questionnaire (CAR). We suggest that understatement of illicit drug use will be ...
