13. Avaliação do papel diagnóstico e prognóstico da expressão imunoistoquímica de NDRG1, osteonectina, VEGF-A, VEGF-C, Flk-1/KDR, HIF-1 e galectina-3 em espécimes tireoideanos por tissue microarrays / Study of the diagnostic and prognostic role of immunohistochemical expression of NDRG1, osteonectin, VEGF-A, VEGF-C, Flk-1/KDR, HIF-1 and galectin-3 in thyroid specimens by tissue microarray
INTRODUÇÃO: O crescimento e a progressão de diversos tipos de tumores dependem da angiogênese, isto é, a formação de novos vasos sanguíneos. Fatores da família do VEGF (VEGF-A, VEGF-C, Flk-1/KDR) são potentes mediadores da angiogênese e níveis elevados destes fatores podem ser detectados em vários tumores humanos. Outras proteínas como NDRG1, o

14. AvaliaÃÃo da biocompatibilidade do cimento portland, em polpas humanas, apÃs capeamento pulpar direto: estudo morfolÃgico e imunoistoquÃmico. / Evaluation of the biocompatibility of the Portland cement, in human pulp, after direct dental pulp capping: a morphological and imunohistological study
The present study evaluated dental implants with no primary stability and with uncovered threads, inserted in rabbit’s tibias, in the presence of BMP through the value of removal torque and radiographic’s analysis. It was used 6 adult male New Zealand White rabbits, divided in test (4 animals) and control group (2 animals). Two implants (Neodent�

15. Análise da expressão diferencial de genes do folículo ovariano de fêmeas pré-púberes e púberes Bos primigenius indicus (Nelore) por meio da Análise Serial de Expressão Gênica (SAGE) / Analysis of differential gene expression of ovarian follicle from prepubertal and pubertal Bos primigenius indicus (Nelore) females by Serial Analysis of Gene Expression (SAGE)
Puberty is the stage where any mammal, male or female, becomes able to produce viable gametes and manifest complete sexual behavior. These are results from the gradative adjustment between the increase in gonadotrophic activity and the ability of gonads in undergoing simultaneously both steroidogenesis and gametogenesis. One of the major factors interferring

16. Osteonectin mRNA: distribution in normal and transformed cells.
Overlapping cDNA clones encoding bovine osteonectin were isolated from a lambda gt11 expression library constructed from bovine bone cell mRNA. The longest clone, lambda On 17 (insert size 2.0 kb) was studied in detail. The clone was shown to encode osteonectin by hybrid select translation experiments and by DNA sequence analysis. Northern analysis of bone c

17. Human platelets contain and secrete osteonectin, a major protein of mineralized bone.
We have developed a solid-phase competitive radioimmunoassay for human osteonectin, using a monoclonal antibody to bovine osteonectin. The assay is both specific and sensitive, being capable of measuring as little as 10 ng of osteonectin. Osteonectin measurements in parallel serum and plasma samples obtained from healthy individuals showed the plasma level t

18. Osteopenia and decreased bone formation in osteonectin-deficient mice
Bone continuously remodels in response to mechanical and physiological stresses, allowing vertebrates to renew bone as adults. Bone remodeling consists of the cycled synthesis and resorption of collagenous and noncollagenous extracellular matrix proteins, and an imbalance in this process can lead to disease states such as osteoporosis, or more rarely, osteop

19. Osteonectin cDNA sequence reveals potential binding regions for calcium and hydroxyapatite and shows homologies with both a basement membrane protein (SPARC) and a serine proteinase inhibitor (ovomucoid).
Osteonectin is a prominent noncollagenous protein of developing bone. A 2150-base-pair cDNA coding for osteonectin, isolated from a bovine bone cell lambda gt11 expression library, was sequenced and identified by comparison with protein sequence data. The nucleotide sequence predicts that osteonectin contains 304 amino acids, including a 17-residue signal pe

20. Presence of osteonectin/SPARC in mandibular condylar cartilage of the rat.
Osteonectin/SPARC was most abundantly present in adherent osseous tissue of the cartilage explants. In cartilage explants with ossification fronts, it appears to be present in hypertrophic chondroblasts and in the mineralised extracellular cartilage matrix. In a number of cartilage explants it could be demonstrated in the fibroblastic cells of the perichondr
