Pérez, Hernán; Soto Moyano, Rubén; Ruiz, Samuel; Hernández, Alejandro; Sierralta, Walter; Olivares, Ricardo; Núñez, Héctor; Flores, Osvaldo; Morgan, Carlos; López Valladares, Luis; Gatica, Arnaldo; Flores, Francisco J. (2010)Prenatal undernutrition induces hypertension later in life, possibly by disturbing the hypothalamo-pituitary-adrenal axis through programming decreased expression of hypothalamic glucocorticoid receptors. We examined the ...

Soto Moyano, Rubén; Hernández, Alejandro; Ruiz, Samuel; Pérez, Hernán; Paeile, Carlos (1978)The influence of pentazocine on primary cortical evoked potentials was studied in guinea pig under pentobarbital anesthesia. Pentazocine (10 mg/kg, i.v.) increased the latency time of evoked responses to posterior limb ...

Soto Moyano, Rubén; Fernández, Victor; Sanhueza, Miguel; Belmar, Jorge; Kusch, Claudia; Pérez, Hernán; Ruiz, Samuel; Hernández, Alejandro (1999)There is evidence that severe malnutrition started during gestation and continued through lactation affects adversely the morphologic development of the neocortex leading to increased neuronal cell packing density and ...

Environmental deprivation delays the maturation of motor pyramids during the early postnatal period Pascual, Rodrigo; Fernández, Victor; Ruiz, Samuel; Kuljis, Rodrigo O. (1993)The effects of environmental deterioration upon the development of motor cortex was studied in 30 Sprague-Dawley albino rats during lactation (1st-18th postnatal days). The use of Golgi-Cox-Sholl methodology allowed ...

Pérez, Hernán; Ruiz, Samuel; Hernández, Alejandro; Soto Moyano, Rubén (1985)Susceptibility to strychnine of somatosensory responses evoked in the prefrontal cortex was studied in normal and protein-malnourished rats in three groups. (a) The normal group was from mothers fed a 21% casein diet. (b) ...

Pérez, Hernán; Ruiz, Samuel (1995)The effect of electrical and L-glutamate stimulation of the nucleus locus coeruleus (LC) and nucleus raphe magnus (NRM) on multiunit activity evoked in the nucleus tractus solitarius (NTS) by activation of arterial ...

Ruiz, Samuel; Pérez, Hernán; Hernández, Alejandro; Ramirez, Maritza; Fernandez, Monica; Soto Moyano, Rubén (Informa Healthcare, 1986)The effect of early postnatal malnutrition on the responsiveness of the rat prefrontal cortex was studied by determining excitability thresholds and fatigability to direct cortical stimulation. Malnutrition imposed during ...

Soto Moyano, Rubén; Alarcon, Sergio; Hernández, Alejandro; Pérez, Hernán; Ruiz, Samuel; Carreño, Paz; Kusch, Claudia; Belmar, Jorge (1998)Prenatal malnutrition results in increased concentration and release of central noradrenaline, a neurotransmitter that is an important regulator of normal regressive events such as axonal pruning and synaptic elimination. ...
-
Pérez, Hernán; Ruiz, Samuel; Soto Moyano, Rubén (2002)Prenatal malnutrition-induced fetal growth retardation in the rat results in elevated arterial blood pressure at adulthood. To test the contribution of cardiovascular sensory C fibers in the hypertensive state, arterial ...

Navarrete, Mario; Núñez, Héctor; Ruiz, Samuel; Soto Moyano, Rubén; López Valladares, Luis; White Ortiz, Allan; Pérez, Hernán (2007)Prenatal undernutrition is known to disturb the hypothalamo-pituitary-adrenal (HPA) axis, possibly through the programming of decreased expression of hypothalamic and pituitary glucocorticoid receptors. To test this ...

Pérez, Hernán; Ruiz, Samuel; Inostroza, Hector; Perretta, Marco (1992)The effects of intracerebroventricular (i.c.v.) administration of substance P (SP) and γ-aminobutyric acid (GABA) on responses evoked in the nucleus tractus solitarii (NTS) by electrical stimulation of the ipsilateral ...
