- ItemSomente MetadadadosAgressividade em meninos e meninas: avaliações feitas por mães(Universidade Federal de São Paulo (UNIFESP), 2018-03-19) Araujo, Fernanda Ribeiro de [UNIFESP]; Oliveira-Monteiro, Nancy Ramacciotti de [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: Aggressiveness May Be Defined As Any Form Of Behavior Intended To Hurt / Injure A Living Being. It Can Be Differentiated Into Direct Aggressiveness (Manifested By Behaviors With The Use Of Force, Aiming To Physically Harm The Other) And Indirect / Hostile (Subtle And Veiled Behaviors To Inflict Damage On The Inner World Of The Other). Direct Aggression Is More Presented By Boys, While Hostile Is More Commonly Used By Girls. Authors Suggest The Interaction Of Biological, Social And Cultural Factors For The Determination Of These Differences Between The Sexes. The Greatest Demand For School Psychology Services In Brazil Is For School-Age Children With Complaints Of Aggression. Objective: To Describe And Compare The Frequency Of Direct Aggression In Children, Considering: Gender, Age Ranges (7 And 8 Years, 9 And 10 Years) And Parental Styles. Method: Were Investigated 47 Mothers Of Boys And Girls Who Live In A Municipality Of Santos (Sp) That Responded To The Child Behavior Checklist For Ages 6-18,
- ItemAcesso aberto (Open Access)Avaliação da relação entre a disponibilidade de chumbo, baixo rendimento acadêmico e agressividade em estudantes(Universidade Federal de São Paulo (UNIFESP), 2016-02-29) Tavares, Letícia Fátima da Silva [UNIFESP]; Assunção, Nilson Antonio de [UNIFESP]; http://lattes.cnpq.br/4183619506352119; http://lattes.cnpq.br/6411404982882021; Universidade Federal de São Paulo (UNIFESP)This study was conducted to quantify lead in the school environment and nails of students between 11 and 15 years of the city of Diadema - SP and the correlation between this data and socio-behavioral profile of these students. The focus was the neurocognitive system, where it aimed to verify the existence of correlation between the levels of lead present in the school environment and nails of students, and low academic achievement levels and aggressiveness of the same. A control group of students from the city of Varginha - MG was also analyzed in order to compare the lead of availability at school and nails of the students, in addition to academic performance and aggressiveness thereof to academic performance and aggressiveness of Diadema students - SP, always correlating this data to lead poisoning. The lead of this analysis the environment have been carried out by Fluorescence Spectroscopy portable X-ray and biological samples (nails) collected were quantified by Atomic Absorption Spectroscopy in Graphite Furnace. They were also applied social and behavioral questionnaires acquired by Achenbach System of empirically based Assessment (ASEBA) that are suitable for the needs of this study. The questionnaires were applied to students, parents and teachers of these students investigated, in order to correlate behavioral attitudes, academic performance and lead contamination levels. Lead concentrations found in the school environment were in the range 10-12089 mg kg -1 to school in Diadema - SP and in the range 0-1000 mg kg-1 for school Varginha - MG. In nails, lead concentrations were found in the range 0,11 to 16,74 ± 0,001-0,57 mg Pb / g nail in the school of Diadema - SP and 0,22 to 11,36 ± 0,00 ? 0,73 g Pb / g nail in school Varginha - MG. According to the behavioral methodology, students of Diadema - SP exhibit more aggressive behavior and poorer cognitive performance compared to students Varginha - MG. We hope, with this work, contribute to the development of public policies that assist in the elimination of lead contamination especially in children and adolescents, with lead as one of the possible causes for the low academic performance and aggressiveness of the same.
- ItemSomente MetadadadosDelayed physical and neurobehavioral development and increased aggressive and depression-like behaviors in the rat offspring of dams fed a high-fat diet(Elsevier B.V., 2013-12-01) Giriko, Catherine Assuka [UNIFESP]; Andreoli, Carla Albuquerque [UNIFESP]; Mennitti, Lais Vales [UNIFESP]; Hosoume, Lilian Fazion [UNIFESP]; Souto, Tayane dos Santos [UNIFESP]; Silva, Alexandre Valotta da [UNIFESP]; Mendes-da-Silva, Cristiano [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Early maternal exposure to a high-fat diet (HFD) may influence the brain development of rat offspring and consequently affect physiology and behavior. Thus, in the present study, we investigated the somatic, physical, sensory-motor and neurobehavioral development of the offspring of dams fed an HFD (52% calories from fat, mainly saturated) and the offspring of dams fed a control diet (CD - 14.7% fat) during lactation from the 1st to the 21st postnatal day (P). Maternal body weights were evaluated during lactation. in the progeny, somatic (body weight, head and lengths axes) and physical (ear unfolding, auditory conduit opening, eruption of the incisors and eye opening) development and the consolidation of reflex responses (palm grasp, righting, vibrissa placing, cliff avoidance, negative geotaxis, auditory startle response and free-fall righting) were determined during suckling. Depressive and aggressive behaviors were tested with the forced swimming test (FST) and the foot-shock test on days 60 and 110, respectively. the open field test was used to assess motor function. Compared to controls, the HFD-pups exhibited decreases in body weight (P7-P21) and body length (P4-P18), but by days P71 and P95, these pups were overweight. All indicators of physical maturation and the consolidation of the following reflexes, vibrissa placing, auditory startle responses, free-fall righting and negative geotaxis, were delayed in HFD-progeny. in addition, the pups from HFD dam rats also exhibited reduced swimming and climbing times in the FST and increased aggressive behavior. No changes in locomotion were observed. These findings show developmental and neurobehavioral changes in the rat offspring of dams fed the HFD during lactation and suggest possible disruption of physical and sensory-motor maturation and increased susceptibility to depressive and aggressive-like behavior.
