1. Use of Inert Gases for the Preservation of Nuclear Blood Cells
Abstract The subject of the study was the stability of human white blood cell membranes subject to noble gases (xenon ad krypton, 0.6 mPa) clathrate cryoanabiosis (‒80°C). A unique portable stainless steel low pressure container with a compartment for flexible plastic container was designed to ensure that the cells are saturated with gases. The samples we

2. Desenvolvimento placentário em quatis: evolução filogenética em carnívoros? / Placental development in quati: phylogenetic evolution in carnivores?
The importance of preservation of brazilian wild species is based on knowledge of their distribution, behavior in the wild and in captivity, and the detailed description of their reproductive biology in order to perpetuate the specie. One of the main impacts of this study is the scientific details of the uterine environment versus the process of placentation

3. Isolation and characterization of detergent-reinstant membranes from erythrocytes / Isolamento e caracterização de membranas eritrocitaria resistentes a detergentes
Detergentes constituem uma das ferramentas mais importantes no estudo de membranas biológicas. A eficiência de um detergente em solubilizar biomembranas e suas proteínas depende de suas propriedades físico-químicas e a solubilização parcial pode resultar em membranas resistentes a detergentes (DRMs). A resistência a detergentes dessas frações membr

4. Actin-interacting and flagellar proteins in Leishmania spp.: bioinformatics predictions to functional assignments in phagosome formation
Several motile processes are responsible for the movement of proteins into and within the flagellar membrane, but little is known about the process by which specific proteins (either actin-associated or not) are targeted to protozoan flagellar membranes. Actin is a major cytoskeleton protein, while polymerization and depolymerization of parasite actin and ac

5. Identification and characterization of genes differentially expressed during arbuscular mycorrhiza development in sugarcane / Identificação e caracterização de genes com expressão diferencial durante o desenvolvimento de micorrizas arbusculares em cana-de-açúcar
Arbuscular mycorrhizae (AM) are mutualistic symbiotic associations between fungi of the order Glomales and most of the terrestrial plants. The molecular mechanisms regulating AM development and efficiency are not well understood so that agricultural large scale application is so difficult. Although so many approaches are being used to the identification of d

6. Study of the interaction between Gal-1 and mast cell / Estudo da interação de galectina-1 e mastócitos
Galectin-1 (Gal-1) belongs to a family of ?-galactoside-binding proteins and is involved in several biological processes, including modulation of the inflammatory response. Mast cells play a critical role in allergic and inflammatory events, however, little is known about the impact of Gal-1 on mast cell biology. In this study, we examined the role of Gal-1

7. Obtençao e caracterização de membranas de PLDLA em aplicação como protese para regeneração nervosa periferica / Obtention and characterization of PLDLA membranes for application as peripheral nervous regenation prosthesis
Nas últimas décadas, polímeros biorreabsorvíveis têm sido utilizados em experimentos biomédicos a fim de buscar materiais com propriedades físicas e mecânicas cada vez mais adequados para a sua aplicação no corpo humano. Com intuito de obter um material polimérico adequado para aplicação como prótese tubular para regeneração do nervo ciático

8. Desenvolvimento osseo e dentario : aspectos biologicos, bioquimicos e moleculares da remodelação da matriz extracelular regulada pelas metaloproteinases de matriz e seus inibidores / Dental and bone development : biology, biochemistry, and molecular aspects of the matrix metalloproteinases and their inhibitors during extracellular matrix remodeling
Our objective was to analyse the spatial-temporal distribution of MMP-2, MMP-9, TIMP-1, TIMP-2 and RECK during development of mineralized tissue (bone, enamel, and dentine) in embryos, newborn, and adult mice by immunohistochemistry and in situ hybridization. During rat amelogenesis, at the secretion phase, MMPs and RECK were immunostained in the ameloblast

9. Efeito do PSI na inibição do proteassoma 20S de Trypanosoma cruzi
In recent decades the proteases of protozoa parasites have emerged as potential therapeutic targets. One of them, the 20S proteasome, is a self-compartimentalizing protease that plays a crucial role in cell biology regulating several cellular processes including proteins degradation, cell-cycle control, and antigens presentation. In this sense, the main obje

10. Perfil de expressão genica de leucemias agudas por tecnica de microarranjo (microarrays) / Study of gene expression profile in acute leukemias by microarray assay
The development of gene expression assays, such as cDNA microarrays, has permitted the simultaneous study of several genes; one of this methods is the cDNA microarrays. These investigations contribute to the classification of diseases, comprehension of tumoral biology and, finally, the determination of genetically related prognostic factors. In this present

11. Anopheles albitarsis Embryogenesis: Morphological Identification of Major Events
Anopheles albitarsis embryogenesis was analyzed through confocal microscopy of clarified eggs. Using Drosophila melanogaster as reference system, the major morphogenetic events (blastoderm, gastrulation, germ band extension, germ band retraction, dorsal closure) were identified. The kinetics of early events is proportionally similar in both systems, but late

12. Preparação e caracterização de dispersões de anfifílicos sintéticos / Preparation and characterization of dispersions of synthetic amphiphiles
Dioctadecyldimethylammonium chloride (DODAC) liposomes with 0.51µ mean external diameter and sharp phase transitions were obtained by chloroform vaporization and compared with (small) sonicated DODAC vesicles. Sucrose was impermeant through large DODAC liposomes and sonicated vesicles and was used for internal volume determinations. The apparent interna
