Open field exposure facilitates recovery from an aversive emotional event: Involvement of adrenergic and cholinergic transmitter systems
(Elsevier Ireland, 2016-10)
Successive negative contrast (SNC) is an incentive relativity procedure that has been widely used to model emotional reactivity in rodents. The reward downshift experienced during SNC is thought to result in frustration. ...
Consummatory suppression due to incentive downshift is not a consequence of enhanced search behavior
(Elsevier Science, 2013-06)
Rats shifted from 32% to 4% sucrose solution consume less from the 4% solution than rats that experience only the 4% solution. This consummatory suppression, a phenomenon known as consummatory successive negative contrast ...
Determination of the position of the N-O function in substituted pyrazine N-oxides by chemometric analysis of carbon-13 nuclear magnetic resonance data
(Elsevier Science, 2013-07)
Investigations were carried out app lying NMR spectroscopy for the unambiguous determinatio n of the position of the N-oxide function in a set of 2-substitute d pyrazine N-oxides synthesized in our group. Applying chemometric ...
Casos Clínicos Endometriosis diafragmática: a propósito de un caso
(Sociedad Chilena de Obstetricia y Ginecología, 2016)
Background: Endometriosis affects between 5 to 15% of women of reproductive age. Thoracic presentation entity is infrequent (less than 1% of all cases of endometriosis) and may be located in airway parenchyma, pleura or ...

Effect of open field exploration on frustration´s memory: Implications of the adrenergic system
(Sociedad Argentina de Investigación en Neurociencias, 2013)
When the subjects are exposed to a novel situation pre training or pre testing in a specific learning situation, its retrieval is modulated(Izquierdo & McGaugh,1985,1987). This phenomenon involves a complex series of ...
Sperm parameters associated to reproductive ecology in two snakes species
(Herpetologists League, 2011-03)
The effect of temperature on sperm dynamic parameters in ectotherms in general, and reptiles in particular, remains poorly understood due to the lack of consistent evidence. As a group, snakes show considerable variability ...
Maternal dietary carotenoids mitigate detrimental effects of maternal GnRH on offspring immune function in Japanese quail (Coturnix japonica)
(Wiley, 2013-12)
Maternal resources deposited in eggs can affect the development of several offspring phenotypic traits and result in trade-offs among them. For example, maternal androgens in eggs may be beneficial to offspring growth and ...
Between illusión and disenchantment: varieties of capitalism in Chile and argentina (1975-2010)
(2015)
During the last three decades, both Argentina and Chile have experienced capitailistrevolutions 'from above', which have transformed relationships between firms, workers and the state. These transformations have common ...
