1. Determinação da concentração inibitória mínima de antibióticos contra ureaplasmas isolados de bovinos pela inibição de crescimento e citometria de fluxo. / Determination of minimum inhibitory concentration of ureaplasmas isolated from cattle by inhibition of growth and flow citometry.
Os Mollicutes causam doenças em várias espécies animais de importância econômica, inclusive em bovinos. Neste estudo, foi avaliada por concentração inibitória mínima (CIM) e citometria de fluxo, a atividade de oito agentes antibacterianos (enrofloxacina, ciprofloxacina, gentamicina, claritromicina, cloranfenicol, oxitetraclina, tiamulina e tilosina)

2. Avaliação das características da motilidade (CASA), morfologia e funcionalidade da membrana plasmática (HOST) de espermatozóides bovinos sexados por cimetria de fluxo / Assesment of Motility Chacarteristics (CASA), morphology; plasmatic membrane funcionality (HOST) in flow citometry sex sorted bovine sperm
Sex selecting has a huge impact in dairy and beef production. The only way commercially viable to obtain sex selecting nowadays, is a flow citometry sex sorted sperm technique. Currently sex sorted sperm have been used regularly in Artificial Insemination programs. Meanwhile, there are limitations about non return rate in farm conditions, superficially expla

3. Possíveis efeitos antineoplásicos e mieloprotetores da Ipomoea carnea e de seu princípio ativo, a suainsonina, em camundongos / Possible antineoplastic and mieloprotective effects of Ipomoea carnea and its active principle swainsonine in mice
Ipomoea carnea is a toxic plant widely distributed in Brazil and other tropical countries. Among its active principles I. carnea has the indolizidine alkaloid swainsonine, which inhibits intracellular enzymes (the lysosomal α-mannosidase and the Golgi mannosidase II) and alters membrane receptors and adhesion molecules. It is known that swainsonine pre

4. Efeitos da separação materna sobre o comportamento, a imunidade inata e o crescimento tumoral / Maternal separation effects on the behavior, innate immunity and tumor growth
Maternal separation is one model of stress/anxiety induction. We know about it that the mammals normal emotional behavior development depends on the interaction between mother and younglet. Beside this, early life stressed events can induce deletery effects in immune response and to illness resistance for all life long. In this work we searched for the mater

5. Azidiol comprimido como conservante do leite cru destinado a contagem bacteriana por citometria de fluxo.
The objective of the present work was to compare preservative bacteriostatic azidiol in the liquid and compressed forms, sterilized or not for gamma radiation or ethylene oxide, in the preservation of raw milk for the analysis of microbial counting by flow citometry (Bactocount IBC 150®, Bentley Inc.). The results were automatically converted through a curv

6. Análise da variabilidade genética de Paspalum Notatum Flugge (Poaceae, Panicoideae) com o uso de marcadores moleculares, morfológicos e citometria de fluxo
O gênero Paspalum L. compreende aproximadamente 400 espécies no mundo e cerca de 220 no Brasil. Paspalum é ecologicamente e economicamente importante e tem sido utilizado como pastagem. Paspalum notatum Flügge (grama-forquilha) é uma valorosa gramínea forrageira nos subtrópicos. Esta espécie consiste de vários biótipos sexuais (diplóides) e apomí

7. Analise dos efeitos e dos mecanismos de ação do fator de crescimento transformante- beta 1, interferon gama e iclosporina A na transdiferenciação dos fibroblastos gengivais em miofibroblastos / Effects of transforming growth factor- beta 1, interferon gamma and cyclosporin A on transdifferentiation of gingival fibroblasts in myofibroblasts
Myofibroblasts are the main cellular type involved in extracellular matrix deposition in fibrotic diseases. Relatively little is known about the underlying mechanisms that regulate myofibroblast emergence (transdifferentiation), however the regulatory cytokine transforming growth factor-beta 1 (TGF- beta 1) has been traditionally considered an inducer of the

8. Efeitos agudos do exercÃcio resistido sobre linfÃcitos totais, CD4 e CD8 de idosas
Introduction - Physical exercise has been recommended to minimize the effects of the aging process and resistance training has been recognized as a type of exercise efficient in increase muscle strength and mass of older individuals. On the other hand, high intensity exercise is associated with a higher incidence of illness in athletes, particularly those of

9. Avaliação dos efeitos do extrato etanólico, resíduo butanólico e resíduo aquoso de Pfaffia paniculata sobre o crescimento do tumor de Ehrlich em suas formas ascítica e sólida / Evaluation of effects of the ethanolic extract, butanolic residue and aqueous residue of Pfaffia paniculata on the development of Ehrlich tumor in its ascitic and solid forms
The roots of Pfaffia paniculata have been popularly used for various purposes, as well as an adjuvant for cancer therapy. Recently we have shown that the powdered roots of Pfaffia paniculata promote an attenuation of the Ehrlich tumor growth in its ascitic form. The aims of the present study were to characterize the effects of the ethanolic extract, aqueous

10. Effect of Toxoplasma gondii infection on immune related tissue gene expression in pigs / Efeito da infecção pelo Toxoplasma gondii na expressão de genes associados à resposta imune em tecidos de suínos
Toxoplasmosis is a widespread zoonosis affecting humans and large range of animal species worldwide. Serological surveillance indicates high infection rates, but rarely is associated to severe disease. T. gondii (Tg) infection induces a strong IFN-γ dominated immune response that rapidly controls parasite replication. Pig resistance to toxoplasmosis was

11. Resposta imune de bovinos vacinados com peptídeo sintético SBm7462 com vistas ao controle do Boophilus microplus (Canestrini, 1887) / Immune response of vaccinated bovine with synthetic peptide SBm7462 to the control of the Boophilus microplus (Canestrini, 1887)
Bovines of three and four month of old age received monthly and subcutaneously, three immunizations of synthetic peptide SBm7462 emulsified in saponin. The development both cellular and humoral immune response were evaluated. Its was achieved identifying the IgG1 and IgG2 antigen specific isotypes, determining of the profile of circulating lymphocytes (CD4+,

12. Resposta imune em ratos com encefalomielite alergica experimental aguda tratados com a substancia P
Substance P centrally injected (ICV) in rats acts on the autonomic nervous system and the hypotha1amic-pituitary-adrenal axis (HPA) to moduJate innate llmnune function and iDf1ammatory response in autoimmune diseases. The effects of modulation in migration and in natural killer cell activity of splenocytes in these systems were studied in experimental allerg
