1. Impressions of the chronic 900-MHz electromagnetic field in the prenatal period on Purkinje cells in male rat pup cerebella: is it worth mentioning?
SUMMARY OBJECTIVE: The aim of this study was to examine the changes on the Purkinje cells in the cerebella of male rat pups born to pregnant dams that were exposed to an electromagnetic field in the prenatal period. METHODS: The first stage of the study involved 12 Sprague-Dawley rats, 6 male and 6 female, weighing between 180 and 250 g. The female rats in

2. Environmental enrichment reduces brain excitability in adult rats overnourished during lactation
RESUMO Objetivo: Este estudo analisou se a exposição ao ambiente enriquecido durante a fase juvenil da vida interferiria na atividade elétrica do cérebro de ratos adultos. Além disso, a presente pesquisa também investigou se esse provável efeito na atividade elétrica cerebral poderia ser afetado pela hipernutrição durante a lactação. A eletrofis

3. Evaluation of the effects of Uncaria rhynchophylla alkaloid extract on LPS-induced preeclampsia symptoms and inflammation in a pregnant rat model
Excessive pro-inflammatory cytokines result in adverse pregnancy outcomes, including preeclampsia-like phenotypes, and fetal growth restriction. Anti-inflammation might be an effective therapy. The aim of this research was to investigate whether Uncaria rhynchophylla alkaloid extract (URE), a highly safe anti-inflammation constituent of the herb, can inhibit

4. Neonatal tobacco smoke reduces thermogenesis capacity in brown adipose tissue in adult rats
Maternal smoking is a risk factor for progeny obesity. We have previously shown, in a rat model of neonatal tobacco smoke exposure, a mild increase in food intake and a considerable increase in visceral adiposity in the adult offspring. Males also had secondary hyperthyroidism, while females had only higher T4. Since brown adipose tissue (BAT) hypofunction i

5. Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats
Abstract Reports have indicated that serotonin plays an important role in cell migration and differentiation during the organogenesis of several tissues, including the oral types. Administration of selective serotonin reuptake inhibitor (SSRI) drugs during pregnancy could affect the delivery of serotonin to embryonic tissues altering its development. Object

6. Maternal Exercise during Pregnancy Increases BDNF Levels and Cell Numbers in the Hippocampal Formation but Not in the Cerebral Cortex of Adult Rat Offspring
Clinical evidence has shown that physical exercise during pregnancy may alter brain devel- opment and improve cognitive function of offspring. However, the mechanisms through which maternal exercise might promote such effects are not well understood. The present study examined levels of brain-derived neurotrophic factor (BDNF) and absolute cell num- bers in

7. Temporal profile of intestinal tissue expression of intestinal fatty acid-binding protein in a rat model of necrotizing enterocolitis
OBJECTIVES: Necrotizing enterocolitis is a severe multifactorial intestinal disorder that primarily affects preterm newborns, causing 20-40% mortality and morbidity. Intestinal fatty acid-binding protein has been reported to be a biomarker for the detection of intestinal injuries. Our aim was to assess intestinal tissue injury and the molecular expression o

8. Effect of postnatal intermittent hypoxia on locomotor activity and neuronal development in rats tested in early adulthood
The present study evaluated the effects of postnatal intermittent hypoxia on locomotor activity and neuronal cell survival in early adulthood rats. During a critical period of brain development on postnatal day (PD) 7-11, male rat pups were exposed to intermittent hypoxia and randomly assigned to three experimental groups: (1) intermittent hypoxia, (2) normo

9. L-FABP and I-FABP expression in newborn rats changes inversely in the model of necrotizing enterocolitis
PURPOSE: To determine the expression of hepatic L-FABP and intestinal I-FABP in an experimental model of necrotizing enterocolitis (NEC) in neonatal rats.METHODS: Newborn Sprague-Dawley rats were divided into four groups: Control (C1) - exclusive breastfeeding at the first and sixth procedures (C6), NEC1 - fed formula milk and submitted to hypoxia and hypoth

10. Mild environmental intervention in mother-infant interactions reduces social play behavior in rats
During early life, animals are sensitive to environmental events that may lead to short-term and long-lasting changes in their neurobiology and behavior, which could be related to increased risk for psychopathology. Neonatal handling is an experimental intervention in the mother-infant relationship. Based on previous studies, it is known to decrease rat pups

11. AÇÃO FARMACOLÓGICA DO 3-ALQUINIL SELENOFENO EM MODELOS DE CONVULSÃO EM RATOS JOVENS / PHARMACOLOGICAL ACTION OF 3-ALKYNYL SELENOPHENE ON MODELS OF SEIZURES IN RAT PUPS
As convulsões têm conseqüências importantes em termos de mortalidade e qualidade de vida da população afetada, sendo um fator de risco para o desenvolvimento de alterações cognitivas e anormalidades comportamentais. Tendo em vista as promissoras propriedades farmacológicas das moléculas contendo selênio, no artigo 1 avaliamos a ação anticonvulsi

12. Estresse pré-natal e suas repercussões sobre o cuidado maternal e comportamento de ratos a curto e a longo prazo
In humans and rodents, stress during pregnancy has produced offspring with high levels of anxiety, impaired learning and memory, changes in maternal care and social behavior deficits. Most prenatal stress protocols have attributed their results to the vulnerability of the intrauterine period. However, studies show that the consequences caused by this action
