1. Acrylamide reduces plasma antioxidant vitamin levels in rats due to increased oxidative damage
RESUMO Objetivo A acrilamida é um químico potencialmente neurotóxico e carcinogênico, sendo naturalmente criada durante o processo de aquecimento de alimentos ricos em carboidratos, como batatas fritas e cereais matinais. Dado que o composto pode ser ingerido através do consumo de alimentos, o presente trabalho teve por objetivo investigar o seu efeito

2. Avaliação espacial e temporal de aspectos sanitários de reservatórios com captação de água para abastecimento em SP com ênfase em cianobactérias e cianotoxinas
RESUMO A presença de cianobactérias e cianotoxinas em reservatórios no estado de São Paulo constitui um desafio para produção de água potável. Sete reservatórios utilizados para abastecimento público, monitorados pela Companhia Ambiental do Estado de São Paulo (CETESB), foram analisados em relação a cianobactérias, microcistina e indicadores de

3. Propranolol inhibits myocardial infarction-induced brown adipose tissue D2 activation and maintains a low thyroid hormone state in rats
Considering the recognized role of thyroid hormones on the cardiovascular system during health and disease, we hypothesized that type 2 deiodinase (D2) activity, the main activation pathway of thyroxine (T4)-to-triiodothyronine (T3), could be an important site to modulate thyroid hormone status, which would then constitute a possible target for β-adrenergic

4. Short-term use of resveratrol in alloplastic graft material applied with calvarial bone defects in rats
Abstract Purpose: The effects of resveratrol administration on calvarial bone defects with alloplastic graft material was investigated for osteoinductive reaction and bone development in rats. Methods: Healthy male rats were randomly divided into 3 groups consisting of 10 rats. Groups were as follows: control (defect) group, defect + graft group, and defec

5. Remoção do 2,4-D em amostras de águas pela adsorção em leitos fixos de carvão ativado granular em escala reduzida
RESUMO O objetivo deste trabalho foi avaliar, por meio dos testes rápidos de coluna em escala reduzida, a capacidade de adsorção do carvão ativado granular (CAG) na remoção do ácido 2,4-diclorofenoxiacético (2,4-D) em amostras de água ultrapura e de água filtrada proveniente de estação de tratamento de água. Os valores da capacidade de adsorçã

6. Assessment of a Fully Optimized DPX-Based Procedure for the Multiclass Determination of Pesticides in Drinking Water Using High-Performance Liquid Chromatography with Diode Array Detection
In this study, a disposable pipette extraction (DPX)-based procedure was fully optimized for the multiclass determination of 12 pesticides, with significant differences in their physicochemical properties, using high-performance liquid chromatography coupled with diode array detection (HPLC-DAD). The variables optimized were type of extraction phase, sample

8. Eucalyptus oil to mitigate heat stress in broilers
ABSTRACT The objective of this study was to evaluate performance, hematological parameters, leukocyte counts, and respiratory microbiota of broilers under heat stress receiving eucalyptus oil supplementation. Cobb broilers (n = 1200) were randomly distributed on the first day of life in a factorial arrangement with additional treatment (2 × 2 + 1) with two

9. Guideline values and human risk assessment for the presence of anti-inflammatory drugs remaining in drinking water after lab scale treatment
Abstract This study aimed to determine whether the anti-inflammatory drugs that are most commonly consumed in Brazil, including diclofenac, ketoprofen, naproxen, indomethacin, ibuprofen and acetaminophen, are present in drinking water and to derive guideline values to characterize the human risk. These pharmaceuticals were quantified in surface waters by LC-

10. Risk factors of Helicobacter pylori infection in an urban community in Northeast Brazil and the relationship between the infection and gastric diseases
Abstract INTRODUCTION: Helicobacter pylori, a water contaminant, is the primary pathogenic agent associated with gastric diseases in humans. Exposure to H. pylori is more likely higher in developing countries. This study aimed to evaluate the risk factors associated with H. pylori infection in patients undergoing endoscopy to validate the cause of dyspeptic

11. Efficacy of Zinc/Creatine Supplementation on Improving Growth Performance of Local Balady Chicks
ABSTRACT An experiment was designed to study the efficacy of Zinc and or creatine monohydrate (CMH) supplementation, either alone or in combination, on improving growth performance of Balady chicks. A total number of 144 Balady chicks were randomly divided into four equal groups. The first treatment was fed the basal diet and served as control, while groups

12. High consumption of sucrose induces DNA damage in male Wistar rats
ABSTRACT The purpose of this study was to determine the effects of the high consumption of sucrose on the levels of DNA damage in blood, hippocampus and bone marrow of rats. Male Wistar rats were treated for 4 months with sucrose (10% for 60 initial days and 34% for the following 60 days) in drinking water, and then, glycemia and glycated hemoglobin (A1C) we
