(John Wiley & Sons Inc, 2021-03)
Alcohol (ethanol) use is almost normative by late adolescence, in most western countries. It is important to identify factors that distinguish those who progress from alcohol initiation to sustained use of the drug, from ...
Negative interactions between two SW Atlantic intertidal crabs in soft-bottom habitats
(Springer, 2007-12)
The intertidal crabs Chasmagnathus granulatus and Cyrtograpsus angulatus coexists across the SW Atlantic intertidal. Previous studies in this region suggest that C. granulatus displace C. angulatus in soft sediment where ...
The activation of histamine-sensitive sites of the ventral hippocampus modulates the consolidation of a learned active avoidance response in rats
(Elsevier Science, 2008-05)
Previous evidence from our laboratory has shown that histamine receptors located into the ventral hippocampus modulate learning and memory processes. Stimulation of histamine hippocampal sensitive receptors during the ...

Cerebrovascular disease with and without stroke: Cognitive and clinical profiles
(Research Trends, 2010-05)
Cerebrovascular disease (CVD) patients with and without stroke were compared using clinical and neurological criteria, Magnetic Resonance Imaging (MRI) and cognitive impairment including dementia. The sample comprised 143 ...
Effect of social isolation on 24-h pattern of stress hormones and leptin in rats
(Pergamon-Elsevier Science Ltd, 2006-03)
This work analyzes the effect of social isolation of growing male rats on 24-h changes of plasma prolactin, growth hormone, ACTH and leptin, and on plasma and adrenal corticosterone concentrations. At 35 days of life, rats ...

(Entomological Society of America, 2011-08)
The long-term effects of methoxyfenozide on the longevity and reproductive processes of beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), adults were assessed after exposure by ingestion. Methoxyfenozide ...
Reduction of skull size in South American sea lions reveals density-dependent growth during population recovery
(Inter-Research, 2010-12)
Craniometrical data of male and female skulls collected from 1974 to 2007 were used to test the hypothesis that the somatic growth of South American sea lions Otaria flavescens in northern Patagonia has been affected by a ...
Ancestral genetic legacy of the extant population of Argentina as predicted by autosomal and X-chromosomal DIPs
(Springer Heidelberg, 2021-02)
Aiming to determine their ancestry diagnostic potential, we selected two sets of nuclear deletion/insertion polymorphisms (DIPs), including 30 located on autosomal chromosomes and 33 on the X chromosome. We analysed over ...
