1. Splenic ischemic preconditioning attenuates oxidative stress induced by hepatic ischemia-reperfusion in rats
Abstract Purpose: To evaluate the effects of splenic ischemic preconditioning (sIPC) on oxidative stress induced by hepatic ischemia-reperfusion in rats. Methods: Fifteen male Wistar rats were equally divided into 3 groups: SHAM, IRI and sIPC. Animals from IRI group were subjected to 45 minutes of partial liver ischemia (70%). In the sIPC group, splenic ar

3. Description of training loads using whole-body exercise during high-intensity interval training
OBJECTIVES: To describe external training load and internal training load through sets of a single session of high-intensity interval training (HIIT) body work. METHODS: Twenty male individuals (24±3 years) performed a HIIT body work protocol consisting of a single bout of exercise with 1:1 stimuli. The exercises used were 30 min in duration with “all-o

4. Intraperitoneal Administration of Silymarin Protects End Organs from Multivisceral Ischemia/Reperfusion Injury in a Rat Model
Abstract Objective: To determine whether intraperitoneal silymarin administration has favorable effects on the heart, lungs, kidney, and liver and on oxidative stress in a rat model of supraceliac aorta ischemia/reperfusion injury. Methods: Thirty male Wistar albino rats were divided equally into three groups: sham, control, and silymarin. The control and

5. Evaluation of multidrug resistance-1 gene C>T polymorphism frequency in patients with asthma
OBJECTIVES:Asthma is a chronic inflammatory lung disease characterized by bronchial hyperresponsiveness and airflow obstruction. Genetic and oxidative stress factors, in addition to pulmonary and systemic inflammatory processes, play a pivotal role in the pathogenesis of asthma. The products of the multidrug resistance-1 gene protect lung tissue from oxidati

6. Tocotrienol supplementation in postmenopausal osteoporosis: evidence from a laboratory study
OBJECTIVE: Accelerated bone loss that occurs in postmenopausal women has been linked to oxidative stress and increased free radicals. We propose the use of antioxidants to prevent and reverse postmenopausal osteoporosis. This study aimed to examine the effects of tocotrienol, a vitamin E analog, on bone loss due to estrogen deficiency. Our previous study sh

7. Atividade antioxidante de extratos e compostos isolados de Eugenia umbelliflora e Rapanea ferrugínea / ANTIOXIDANT ACTIVITY OF ISOLATED COMPOUNDS AND EXTRACTS OF Eugenia umbelliflora and Rapanea ferruginea
Eugenia umbeliflora is popularly known as baguaçu, guapê or guaramirim in Portuguese and Brazilian Cherry in English. This species is used in popular medicine to treat diseases such as arthritis, rheumatism and diabetes, although there have been few biological studies to verify the effectiveness of these extracts. Rapanea ferruginea is popularly known as c

8. Estimativa de um índice de estresse hídrico para a cultura da cana-de-açúcar com base na temperatura foliar / Estimating of crop water stress index to sugarcane based on the canopy temperature
The objective of this work was to evaluate the behavior of leaf temperature and transpiration of sugarcane under different matric and meteorological conditions to estimate a crop water stress index (IEHC), which can be applied in irrigation management and estimates of productivity. Because of the need to apply water stress to plants, the experiment was condu

Medida da capacidade antioxidante de fluidos biologicos por voltametria de pulso diferencial associada ao uso de surfactante como resposta as adaptações geradas pelo exercicio / Antioxidant capacity measurement of biological fluids by differential pulse voltammetry associated to surfactant as respose to generated adaptations by the exercise
Aumento na formação de espécies reativas de oxigênio como conseqüência do aumento na demanda energética pode aumentar o estado de oxidação celular, contribuindo para um estado redox celular ótimo e o desenvolvimento máximo de força. O poder redutor de amostras biológicas reflete sua capacidade antioxidante, mantida em grande parte pelos antioxid

12. The role of platelet and plasma markers of antioxidant status and oxidative stress in thrombocytopenia among patients with vivax malaria
Malaria remains an important health problem in tropical countries like Brazil. Thrombocytopenia is the most common hematological disturbance seen in malarial infection. Oxidative stress (OS) has been implicated as a possible mediator of thrombocytopenia in patients with malaria. This study aimed to investigate the role of OS in the thrombocytopenia of Plasmo
