Our data support a disproportion between free radicals levels and scavenging systems activity in different cerebral regions of the aging rat. We investigated total reactive antioxidant potential reactivity levels, which represent capacity, rat (cortex, striatum, hippocampus cerebellum). In addition, we have determined several oxidative stress parameters, specifically macromolecules damage (lipid peroxidation carbonyl content), as well enzymes activities areas from young (2 months-old),...
Objective: To evaluate the nutritional status of crack users and to analyze its correlation with drug use profiles. Methods: Cross-sectional study 108 users. Anthropometric data were assessed through body mass index (BMI) bioimpedance (BIA) measurements. A blood test hematocrit, hemoglobin, glucose, lipid profiles was also performed. Crack determined a standardized interview. Results: Based on BMI BIA, most individuals eutrophic (about 70%). Regarding hematological parameters, we found that...
Abstract Excessive salt intake is a common feature of Western dietary patterns, and has been associated with important metabolic changes including cerebral redox state imbalance. Considering that little known about the effect on progeny excessive during pregnancy, present study investigated high-salt diet pregnancy lactation mitochondrial parameters brains resulting offspring. Adult female Wistar rats were divided into two groups ( n 20 rats/group): control standard chow (0·675 % NaCl) or...
This study analyzed and compared the content of isoflavones in 2 soy products, effectiveness as antioxidants, vitro, demonstrated antioxidant effect a diet rats with myocardial infarction (MI). Isoflavone was soybean hypocotyl (SH) isolated protein (ISP). The quality (TAR) quantity (TRAP) antioxidants present samples quantified. amount daidzin higher SH (9 times) genistein ISP (5 times). presented 3-fold increase TAR, while both products exhibited same TRAP. were fed an for 9 weeks. Animals...
Monosialoganglioside (GM1) is a neuroprotective agent that has been reported to scavenge free radicals generated during reperfusion and protect receptors enzymes from oxidative damage. However, only few studies have attempted investigate the effects of GM1 on enzymatic antioxidant defenses brain. In present study, we evaluate systemic administration activity superoxide dismutase (SOD), catalase (CAT) glutathione peroxidase (GSH-Px), spontaneous chemiluminescence total radical-trapping...
Thawing is a complex process that changes the physical and chemical conditions of substance can significantly affect quality food. Thus, this study aimed to evaluate effect different thawing (room temperature, refrigerated temperature microwave) on content bioactive compounds in broccoli (Brassica oleracea var. Avenger) identify which method provides better retention these substances. In methodology, carotenoids, flavonoids vitamin C were analyzed by high-performance liquid chromatography;...
The objective of this study was to evaluate the changes induced by isolated soy protein (ISP)-based diet on glycemia and oxidative stress biomarkers in diabetic rats. Fifteen male Wistar rats (35 ± 4 g, aged 21 days) were assigned three groups: Casein (C group), which received casein-based during experimental protocol; Diabetic treated with (D + C group) that before after diabetes induction; ISP S induction ISP-based for protocol. Diabetes a single dose streptozotocin (50 mg/kg body weight...
Determine associations between the quality of life mothers and nutritional status children.case-control study involving 152 children aged zero to five years, living in coverage area a basic health unit city Porto Alegre. The calculation sample size was estimated as - 76 with at risk/malnutrition (cases) eutrophic (controls). Information collected regarding mothers, measured by instrument World Health Organization, association maternal examined.In relation psychiatric realm, for each child...
Aims: To evaluate the effect of caloric and non-caloric soft drink intake on food consumption, body weight composition, metabolic parameters in rats.Methods: Controlled experimental study which 30 male Wistar rats were divided into three groups given beverage ad libitum during 17 weeks. The as follows, according to offered food: Control group – standard chow water; Caloric chow, drink, Non-caloric water.Results: There was no statistical difference total energy intake, weight, fat deposition...
Resumo Objetivos: analisar a influência da duração do aleitamento materno no comportamento alimentar em crianças de dois seis anos. Métodos: esta revisão foi conduzida acordo com as diretrizes PRISMA. As bases dados SciELO, Lilacs, Embase e PubMed foram pesquisadas usando uma sintaxe específica, para estudos publicados 2000 2020. O Joanna Briggs Institute Critical Appraisal checklist utilizado avaliar o risco viés estudo. Resultados: identificados 26.211 artigos, dos quais sete incluídos Os...
O Programa Nacional de Alimentação Escolar é uma das mais importantes políticas Segurança Alimentar e Nutricional no Brasil, viabilizando a oferta alimentação saudável adequada todos os estudantes matriculados na rede pública da educação básica criando mercados para agricultores familiares. Nesse sentido, partindo do entendimento que inserção alimentos dialoguem com sustentabilidade cultura alimentar escolar poderiam desencadear diversos efeitos positivos contexto local, este artigo busca...
Objetivo: Analisar as situações de risco notificadas para o serviço nutrição em um hospital público do sul Brasil. Método: Estudo retrospectivo das risco, acordo com a Classificação Internacional Segurança Paciente (CISP), registradas no ano 2017 sistema notificações hospital. As análises foram realizadas programa estatístico SPSS versão 21.0. Resultados: Das 172 notificações, 70,3% envolveram pacientes adultos. A maioria aconteceu dias úteis (84,9%); turno da manhã (39,5%). Foram mais...
A obesidade e uma doenca que se caracteriza pelo acumulo em excesso de gordura, prejudicando a saude dos individuos gerando diversas comorbidades como cardiopatias, diabetes mellitus, alguns tipos cânceres ate mesmo efeitos no sistema nervoso central com prejuizo desempenho cognitivo. Dada relevância do assunto, esse artigo busca expor os resultados alcancados um projeto extensao objetiva criar canal comunicacao periodico por meio redes sociais entre academicos profissionais da usuarios...
