1. In vitro Evaluation of PHBV/PCL Blends for Bone Tissue Engineering
The objective of this study was to evaluate Vero cells in in vitro biocompatibility tests with pure PHBV and PCL and 75/25 and 50/50 blends developed for bone tissue bioengineering in dense or porous forms. The biomaterials were characterized morphologically by scanning electron microscopy, (SEM) stereoscopic imaging (SI), and micrometer measurement. Cellula

2. Benefits of oxygen and nitrogen plasma treatment in Vero cell affinity to poly(lactide-co-glycolide acid)
Cell adhesion on materials surface is critical because this phenomenon occurs before other events, as cell spreading, cell migration and cell differentiation. it is commonly accepted that the adhesion of cells on solid substrate is influenced by several substratum surface properties, such as wettability, surface charge, roughness and topography. plasma techn

3. Analysis of the dynamic of origin and fate of trophoblast cells in the maternal-fetal interface of pregnant guinea pig uterus to elucidate inverted yolk sac organization / Análise da dinâmica da origem e destino das células trofoblásticas na interface materno-fetal do útero gestante do cobaio na elucidação da organização da placenta vitelina invertida
A implantação embrionária e a placentação em cobaios são caracterizadas pela presença trofoblastos que se destacam da placenta principal, semelhantes ao trofoblasto extra-viloso de humanos. Nestes animais ultrapassam os limites, e podem ser encontrados infiltrados no profundamente no endométrio e no em ambiente externo ultrapassando aos limites da pa

4. Tratamento com taurina e interferon beta influencia a expressão do complexo de histocompatibilidade principal de classe I (MHC I) e a formação de sinapses em células PC12 / Interferon beta and taurine treatment induce major histocompatibility complex class I (MHC I) upregulation and synapse plasticity in PC12 cells
It has been demonstrated that MHC I up regulation by exogenous treatment with interferon beta (IFN beta) influences the glial reaction and the synaptic elimination process. Also, the amino acid taurine has been shown to positively influence neuronal survival and plasticity. Nevertheless, the establishment of an in vitro model for studying the synaptic format

5. The expression of CD56 antigen is associated with poor prognosis in patients with acute myeloid leukemia
BACKGROUND: The expression of CD56 is considered a bad prognostic factor for overall survival, lower rates or short complete remission and extramedullary invasion but the results are controversial. The importance of validating new prognostic parameters in acute leukemias was the reason to investigate the CD56 expression in blast cells of patients with acute

7. Hematological, biochemical, morphological and cytochemical aspects of blood cells in neotropical Viperidae from Bothrops and Crotalus genus mantained in captivity / Aspectos hematológicos, bioquímicos, morfológicos e citoquímicos de células sangüíneas em Viperídeos neotropicais dos gêneros Bothrops e Crotalus mantidos em cativeiro
Este estudo apresenta um painel de dados hematológicos, bioquímicos, morfológicos e citoquímicos para um grupo de serpentes dos gêneros Bothrops e Crotalus mantidas em cativeiro no Instituto Butantan. Para tanto, amostras de sangue foram colhidas da veia coccígea ventral e processadas de acordo com métodos padronizados. Os resultados alcançados foram

8. Contribution to the studyof chemical comunication in Lutzomyia longipalpis AND Lutzomyia cruzi (Diptera: Psychodidae: Phlebotominae) / Contribuição ao estudo da comunicação química em Lutzomyia longipalpis e Lutzomyia cruzi (Diptera: Psychodidae: Phlebotominae)
Ultrastructural cytochemistry of sex pheromone gland cells in abdominal tergites of Lutzomyia cruzi males showed the presence of large amounts of lipid inclusions, peroxisomes, mitochondria and endoplasmic reticulum profiles. In L. longipalpis it was demonstrated that these lipid inclusions appear in the gland cell cytoplasm about 9 hours after adult emergen

9. Regulação hormonal da prostata de femeas do gerbilo : avaliação estrutural, citoquimica e imunocitoquimica / Hormonal regulation of the gerbil female propstate: morphology, cytochemistry and immunocytochemistry
The female prostate is a functionally active gland found in several species of mammals, including humans and rodents. In adult female gerbils, the prostate presents a paraurethral location, showing close contact with the wall of urethra in its median and distal portions. This gland is homologue to the ventral prostate of male rodents and it is formed by a cl

12. Painel racionalizado de anticorpos monoclonais para leucemias agudas : seu valor diagnostico e prognostico
Acute leukemia is characterized by a c1onal proliferation of haematopoietic stem cell substituting the normal bone marrow. The recent WHO c1assification for acute leukemia separates entities by recurrent cytogenetic abnormalities and immunophenotypic features presenting prognostic impact. We have examined the distribution and impact on survival of the expres
