1. Avaliação da atividade funcional dos neutrófilos sanguíneos em ovelhas primíparas e pluríparas da raça Lacaune
ABSTRACT This study aimed to evaluate the neutrophil oxidative metabolism and phagocytosis of Zymonsan particles of primiparous and pluriparous Lacaune ewes during the first 30 days after lambing. A total of 20 ewes were evaluated, 10 primiparous (GPR) and 10 pluriparous (GPL). Evaluation of basal oxidative metabolism was performed using the nitroblue tetraz

2. EFEITO DO PARASITISMO POR Haemonchus contortus SOBRE O METABOLISMO OXIDATIVO DE LEUCÓCITOS DE OVINOS
Resumo A resposta imune tardia direcionada para eliminação da hemoncose pode ser modulada pelo perfil Th2, sendo os eosinófilos as principais células efetoras responsáveis pela eficiente eliminação do parasita; ou modulada pelo perfil Th1, sendo os neutrófilos as principais células efetoras, que promovem eliminação parasitária mais deficiente, po

3. In vivo phagocytosis and hematology in Astyanax altiparanae, a potential model for surrogate technology
Resumo Apesar do potencial apresentado pela tecnologia de propagação mediada para a aquicultura e conservação de peixes Neotropicais, o pobre entendimento do sistema imune do hospedeiro pode resultar na rejeição e destruição do material do doador. Com isso, se fazem necessários o estudo e o desenvolvimento de métodos para análise tanto dos efeitos

4. Ultrastructure of phagocytes and oocysts of Nematopsis sp. (Apicomplexa, Porosporidae) infecting Crassostrea rhizophorae in Northeastern Brazil
Resumo Este trabalho descreve a morfologia ultraestrutural detalhada do fagócito encarcerando um oocisto de Nematopsis (Apicomplexa) encontrado em Crassostrea rhizophorae, na cidade de Maceió (AL), Brasil. Os hospedeiros muito infectados apresentavam valvas entreabertas com retração fraca e lenta dos músculos abdutores. Número variável de oócitos de

5. 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

6. What are the advantages of living in a community? A microbial biofilm perspective!
Biofilm formation is the preferred mode of growth lifestyle for many microorganisms, including bacterial and fungal human pathogens. Biofilm is a strong and dynamic structure that confers a broad range of advantages to its members, such as adhesion/cohesion capabilities, mechanical properties, nutritional sources, metabolite exchange platform, cellular commu

7. Generation of a triple-fluorescent mouse strain allows a dynamic and spatial visualization of different liver phagocytes in vivo
ABSTRACT Resident and circulating immune cells have been extensively studied due to their almost ubiquitous role in cell biology. Despite their classification under the “immune cell department”, it is becoming increasingly clear that these cells are involved in many different non-immune related phenomena, including fetus development, vascular formation,

8. MICROEMULSION OF BRAZIL NUT OIL AS A NATURAL PRODUCT TO IMPROVE SUPEROXIDE RELEASE IN HUMAN PHAGOCYTES
The aim of this study was to develop and characterize a Brazil nut oil microemulsion system and determine the effect of this microemulsion on the superoxide release in human phagocytes. The microemulsion was formulated using distilled water, Brazil nut as the oily phase, Sorbitan monooleate, Polysorbate 80, and butan-1-ol. Hydrophile-lipophile balance of Bra

9. Phagocytosis and nitric oxide production by peritoneal adherent cells in response to Candida albicans in aging: a collaboration to elucidate the pathogenesis of denture stomatitis
Abstract Elderly denture wearers are commonly affected by Candida-associated denture stomatitis (DS), an inflammatory process of the oral mucosa strongly associated with Candida spp and other microorganisms, as well as local and systemic factors. The impaired immune response against pathogens is among the inherent host factors that have been also associated

10. Decreased phagocytic function in neutrophils and monocytes from peripheral blood in periodontal disease
Phagocytosis by neutrophils and monocytes constitutes the main defense mechanism against bacterial challenges in periodontitis. Phagocytosis by neutrophils has already been evaluated, whereas phagocytic function of monocytes has hardly been addressed so far. Objectives: The aim of this study was to assess phagocytosis by neutrophils and monocytes in periodon

11. Expressão do receptor de macrófago com estrutura de colágeno (MARCO) em macrófagos, células dendríticas e células tumorais após internalização de nanotubos de carbono / Expression of macrophage receptor with collagen structure (MARCO) in macrophages, dendritic cells and tumor cells after internalization of carbon nanotubes
The aplication of nanotechnology emerges with potential for application in the biomedical area, pathological diagnosis and treatment, drug transport and intracellular transport of molecules. Among the nanoparticles, carbon nanotubes (NT) belong to a new class of material for application in the biomedical area. Due to its small size, the NT can be internalize

12. Composto homeopático reduz a liberação de ânion superóxido pelas células mononucleares de ema (Rhea americana)
The action of the "Stress Factor Ostrich (Arenales - Fauna and Flora)" was tested in the release of superoxide anion by cells in the peripheral blood of rhea (Rhea americana). Sixteen samples of 0.5mL of venous blood were collected through the jugular vein in the morning and placed in heparinized tubes. The leukocytes were separated into polymorphonuclear (P
