Differential effect of environment enrichment and social isolation on depressive-like behavior, spontaneous activity and serotonin and norepinephrine concentration in prefrontal cortex and ventral striatum
(2008)
Dawley rats were reared from weaning in either social isolation, standard laboratory conditions, or environmental enrichment. Open-field activity
was assessed at postnatal days 37, 65, 93 and 107 and 1 h before the last ...
Maternal behavior as an early modulator of neurobehavioral offspring responses by Sprague-Dawley rats
(2013)
Maternal care plays an important role as an early modeler of neurodevelopment and brain function,
and its effects remain until adulthood. Such modeling or programming has shown to influence the
stress response and ...
The effect of chronic fluoxetine on social isolation-induced changes on sucrose consumption, immobility behavior, and on serotonin and dopamine function in hippocampus and ventral striatum
(2009-03-02)
This study examined the effect of fluoxetine, a selective serotonin (5-HT) reuptake inhibitor, on isolation-induced changes on sucrose consumption and preference, spontaneous open-field activity, forced swimming behavior, ...
Behavioral and neurochemical characterization of maternal care effects on juvenile Sprague–Dawley rats
(2013)
Maternal care represents a major constituent of early life environment and has the potential to modulate critical
neurobehavioral responses to stress. The aim of the present study was to determine the effects of naturally ...
Sub-chronic administration of St. John’s wort reverses anxiety- and depressive-like behaviors induced by two different protocols of chronic stress
La administración sub-crónica de hierba de San Juan revierte las conductas de ansiedad y depresión inducidas por dos protocolos distintos de estrés crónico
(2017-05-30)
Introduction. St. John’s wort (Hypericum perforatum, HP) is one of the most used herbal medicines. Here we investigated the putative antidepressive- and anxiolytic-like effects of HP, by using a well-validated rat model ...
Un método simple para la recolección, extracción y medición de catecolaminas en orina de adultos mayores
A simple method to collect, extract and measure urinary catecholamines in elderly people
(2007)
La medición de catecolaminas en orina ha sido utilizada tanto para diagnóstico
como para la investigación. Este trabajo propone algunas modificaciones
y condiciones estandarizadas para llevar a cabo la recolección ...
Environmental Enrichment and Physical Exercise Attenuate the Depressive-Like Effects Induced by Social Isolation Stress in Rats
(2020)
We assessed the antidepressant-like effects of environmental enrichment (EE) and
physical exercise (PE) compared with the selective serotonin reuptake inhibitor
fluoxetine against the depression-related neurobehavioral ...
Clinical and Genetic Analysis of Costa Rican Patients With Parkinson's Disease
(2021)
Background: Most research in genomics of Parkinson’s disease (PD) has been done
in subjects of European ancestry, leading to sampling bias and leaving Latin American
populations underrepresented. We sought to clinically ...
Efectos del cuidado materno temprano en el desarrollo del sistema nervioso
(2013)
Ambientes adversos tempranos pueden afectar el desarrollo del sistema nervioso e incluso favorecer la
aparición de desórdenes del estado de ánimo como la depresión y ansiedad. Esta hipótesis ha sido
corroborada a través ...
Diferencias individuales en modelos animales: un enfoque para el estudio de factores neurobiológicos relacionados con depresión
Individual differences in animal models: an approach to study neurobiological factors related to depression
(2014)
El estudio de las diferencias individuales en la prueba de nado forzado (PNF) en ratas permite la identificación
de factores de susceptibilidad o de resistencia en el desarrollo conductas relacionadas con la depresión. ...
