1. Oxidative stress and fish immune system: phagocytosis and leukocyte respiratory burst activity
Abstract Molecular oxygen is a necessary compound for all aerobic organisms, although oxygen is a potent oxidant, which can cause oxidative stress (OS). OS occurs when there is an imbalance between the production of oxidant and antioxidants components, are result of normal cell metabolism, and many of these compounds play a fundamental role in several metabo

3. Effect of hypertonic saline treatment on the inflammatory response after hydrochloric acid-induced lung injury in pigs
OBJECTIVES:Hypertonic saline has been proposed to modulate the inflammatory cascade in certain experimental conditions, including pulmonary inflammation caused by inhaled gastric contents. The present study aimed to assess the potential anti-inflammatory effects of administering a single intravenous dose of 7.5% hypertonic saline in an experimental model of

6. Fc?R e CR3 no lúpus eritematoso sistêmico: variantes polimórficas e sua influência na fagocitose e desgranulação dos neutrófilos / Fc?R and CR in systemic lupus erythematosus: polimorphisms and their influence in the phagocytosis and degranulation of neutrophils
Systemic lupus erythematosus (SLE) is an autoimmune disease in which disease-related and genetic factors and immunosuppressive and cytotoxic therapies all contribute to an increased susceptibility to infections. Factors predisposing to infection include defects in chemotaxis, abnormalities in neutrophil phagocytic activity, decreased immune complex (IC) and

7. Avaliação do efeito de contraceptivos hormonais sobre o sistema complemento / Evaluation of the effect of hormonal contraceptives on the complement system
The occurrence of thrombosis is often associated with the presence of one or more risk factors, which may be genetic and/or acquired, such as hormonal changes that occur during pregnancy, hormone replacement therapy and the use of combined hormonal contraceptives (CHC). The inflammation in turn, is an important body\ s response to the aggression and involves

8. Caracterização e possível papel da modulação oxidativa da parede celular em alterações na sensibilidade de células de tabaco cv. BY-2 a pH baixo durante a retomada do ciclo celular / Characterization and possible role of the oxidative modulation of the cell wall in changes in the sensitivity of tobacco BY-2 cells to low pH during restart of the cell cycle
A acidez do solo é um dos principais fatores limitantes à produção vegetal. Apesar da toxicidade por alumínio ter sido extensamente investigada, pouca atenção tem sido dada ao estresse causado pelo baixo pH em si. Existem diferenças marcantes entre células quanto à sensibilidade ao pH baixo que dependem do seu estado de crescimento e desenvolviment

9. Anti-Helicobacter pylori activity and oxidative burst inhibition by the naphthoquinone 5-methoxy-3,4-dehydroxanthomegnin from Paepalanthus latipes
Helicobacter pylori is a bacterium recognized as the major cause of chronic gastritis and peptic ulcers. Infection by H. pylori induces inflammatory responses and pathological changes in the gastric microenvironment. The host Keywords: immune cells (especially neutrophils) release inflammatory mediators and large 5-methoxy-3,4-dehydroxanthomegnin amounts of

10. Lipopolysaccharide-induced expression of cell surface receptors and cell activation of neutrophils and monocytes in whole human blood
Lipopolysaccharide (LPS) activates neutrophils and monocytes, inducing a wide array of biological activities. LPS rough (R) and smooth (S) forms signal through Toll-like receptor 4 (TLR4), but differ in their requirement for CD14. Since the R-form LPS can interact with TLR4 independent of CD14 and the differential expression of CD14 on neutrophils and monocy

11. Biological activities of extracts from brazilian marine algae / Atividades biológicas de extratos de algas marinhas brasileiras
Algae are important sources of raw material and biological active compounds used in pharmaceutical, cosmetic and food industries. Marine Brazilian red macroalge, Gracilaria birdiae e Gracilaria domingensis, are found in the Brazilian northeast coast and have high potential for industries. The aim of this work was to evaluate the antioxidant activity of the e

12. Evaluation on the involvement of Galatrox, a lactose binding lectin isolated from Bothrops atrox venom, on the inflammatory process / Avaliação do envolvimento da Galatrox, uma lectina ligante de lactodr isolada da peçonha de Bothrops atrox, no processo inflamatório
Lectins are proteins with no enzymatic activity and are able to bind specifically and non-covalently (reversible manner) to carbohydrates. In addition, these proteins are involved in several physiological and pathological events, as embryogenesis, immune response, cancer, and others. Galatrox, a lactose-binding protein, was purified from Bothrops atrox snake
