1. Maternal exposure to trace cadmium affects gonadal differentiation and development in male offspring rats though a star pathway
Abstract To investigate effect and mechanism of maternal exposure to trace cadmium on the differentiation and development in testis of male offspring rats. Thirty-two pregnant female SD rats were randomly divided into 4 groups: CdCl2 treated group (group A) was intraperitoneally injected with CdCl2 (1.5 mg/kg.d); DES group(group B) was subcutaneously injecte

3. The Influence of Light Exposure in Ambiance during Pregnancy inMaternal and Fetal Outcomes: An Experimental Study
Resumo Objetivo Avaliar se a exposição a diferentes luminosidades no ambiente afeta parâmetros reprodutivos de camundongos fêmeas prenhas e o desenvolvimento de sua prole. Métodos Foram selecionados para o estudo 15 camundongos fêmeas albinas prenhas. Os camundongos foram separados em grupos: luz/escuro, luz e escuro. As fêmeas foram eutanasiadas

4. Cardio-respiratory development in bird embryos: new insights from a venerable animal model
ABSTRACT The avian embryo is a time-honored animal model for understanding vertebrate development. A key area of extensive study using bird embryos centers on developmental phenotypic plasticity of the cardio-respiratory system and how its normal development can be affected by abiotic factors such as temperature and oxygen availability. Through the investiga

5. Mild reproductive effects of the Tityus bahiensis scorpion venom in rats
BackgroundScorpion envenoming is a public health problem in Brazil, whereTityus serrulatus and T. bahiensisare considered the most dangerous scorpions. They are well adapted to urbanized environments, and there is an increasing probability of human exposure to these venoms, including during pregnancy. Not much is known about the effects of prenatal exposure

6. HLA-G polymorphism in mother-child transmission of HIV-1 / Polimorfismo do HLA-G na transmissão materno-infantil do HIV-1
The main way of HIV-1 infection in children is mother-child transmission (MTCT). TMI rates estimates for HIV-1 are 3% in pregnant women in antiretroviral therapy and 25 to 30% for untreated ones. Despite the viral exposure during pregnancy, most newborns are not vertically infected, suggesting the existence of protective barriers to TMI of HIV-1. Several fac

7. Gestacional protein restriction triggers hiperanxiety in adulthood due to changes in the bed nucleus of stria the terminalis (BNST) / Avaliação de parâmetros comportamentais e da estrutura tridimensional de neurônios do núcleo da estria terminal de ratos machos adultos expostos à restrição protéica gestacional
In developed and developing countries maternal and child malnutrition has obvious repercussions on the population health f. This is due to changes in ontogenetic development, linked to the manifestation of programmed changes in morphological and functional development of organs and systems. The fetal programming by malnutrition or protein deficiency leads to

8. Maternal drinking behavior and Fetal Alcohol Spectrum Disorders in adolescents with criminal behavior in southern Brazil
Prenatal alcohol exposure can have serious and permanent adverse effects. The developing brain is the most vulnerable organ to the insults of prenatal alcohol exposure. A behavioral phenotype of prenatal alcohol exposure including conduct disorders is also described. This study on a sample of Brazilian adolescents convicted for criminal behavior aimed to eva

9. Embryotoxicity following repetitive maternal exposure to scorpion venom
Although it is a frequent accident in a few countries, scorpion envenomation during pregnancy remains scarcely studied. In the present study, the effects of repetitive maternal exposure to Buthus occitanus tunetanus venom are investigated and its possible embryotoxic consequences on rats. Primigravid rats received a daily intraperitoneal dose of 1 mL/kg of s

10. Prenatal alcohol exposure did not affect impulsivity in rats that performed delay or probability discounting tasks
Individuals who fall under the spectrum of the Fetal Alcohol Syndrome have a higher prevalence of several cognitive disturbances, including a greater probability of being diagnosed with attention-deficit hyperactivity disorder (ADHD). Some of these effects, such as hyperactivity and attentional impairments, are already well established in the literature. The

11. Exposição pré-natal ao etanol: toxicidade, biomarcadores e métodos de detecção
CONTEXTO: A exposição pré-natal ao etanol pode produzir diversos efeitos adversos no desenvolvimento fetal denominados doença espectral do alcoolismo fetal (DEAF). A detecção precoce de exposição ao etanol permite que medidas preventivas sejam tomadas para minimizar os efeitos adversos da exposição. OBJETIVOS: O presente trabalho teve como objetivo

12. Tomada de decisão mediada por tempo e probabilidade em ratos expostos ao álcool antes do nascimento / Decision making mediated by time and probability in rats prenatally exposed to ethanol
Fatores como o tempo de espera ou o risco a ser enfrentado por uma recompensa maior têm um efeito importante e, por vezes, paradoxal no processo de tomada de decisão. O Capítulo I apresenta uma discussão teórica sobre a tomada de decisão mediada por esses dois fatores, bem como sua interligação com o conceito de impulsividade e o Transtorno de Défic
