1. Accident involving a 2-year-old child and Lonomia obliqua venom: clinical and coagulation abnormalities
Poisons of caterpillars have different effects on inflammatory and coagulation systems. This is a case report of a 2-year-old child that accidentally came in contact with several caterpillars of the species Lonomia obliqua. At first, the patient's exams presented abnormal coagulation and decreased fibrinogen, but the patient did not evolve to active bleeding

2. Angiogenesis and schistosomiasis
Angiogenesis has been recognised as a precursor of fibrosis in several pathologic conditions. Its participation has been demonstrated in schistosomiasis, both during periovular granuloma formation and in the genesis of schistosomal periportal fibrosis. Paradoxically, proliferation of new blood vessels, accompanied by production of vascular-endothelial growth

3. Engenharia de tecidos com células-tronco de dentes decíduos e scaffolds injetáveis e a formação de polpa dental funcional / Stem cells from exfoliated deciduous teeth and self-assembling nanofiber and recombinant human collagen I scaffolds allows for the engineering of a functional dental pulp
A translação da regeneração pulpar com células tronco para a clinica requerirá o uso de scaffolds injetáveis. O objetivo foi estudar o comportamento de células tronco obtidas de dentes decíduos exfoliados (SHED) injetados em canais radiculares de pré-molares humanos com ápice aberto com scaffold de colágeno recombinante humano tipo I (rhC-I) e a

4. Análise estrutural do colágeno do tipo I - correlação estrutura : atividade biológica / Structural analysis of type I collagen : structure activities relationships
Além das funções mecânicas, sabe-se que o colágeno do tipo I é um dos componentes mais ativos na modulação das atividades biológicas que ocorrem na matriz extracelular (MEC) tais como a adesão celular, a coagulação e a mineralização do osso. Estes eventos ocorrem nos limites do período D, que é provavelmente o domínio funcional que mais prev

5. Tomographic evaluation of the small airways in the interstitial lung diseases / Avaliação tomográfica do acometimento das pequenas vias aéreas nas doenças intersticiais do pulmão
The pathogenesis of idiophatic pulmonary fibrosis (IPF), the most common form of idiopathic interstitial pneumonias, is not completely understood. It is related to a type I pneumocyte injury with loss of basement membrane integrity and failure of normal re-epithelialization and re-endothelialization leading to fibroblast proliferation and extra cellular matr

6. Histomorphometric evaluation of the female reproductive system of Tropidacaris collaris (Stoll,1813) (Orthoptera: Romaleidae) submitted to three photoperiods / Avaliação histomorfométrica do aparelho reprodutor feminino de Tropidacris collaris (Stoll,1813) (Orthoptera : Romaleidae) submetido a três fotoperíodos
In Brazil, the presence and the increase of the population of grasshoppers are linked, certainly, to the deforestation and to the new types of manipulation of agroforestry cultures, implanted in the cerrado and other regions. Among the species of grasshoppers of economic importance, the Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae) is highlight

7. Resorbable extracellular matrix grafts in urologic reconstruction
PURPOSE: There is an increasingly large body of literature concerning tissue-engineering products that may be used in urology. Some of these are quite complex (such as multilayer patient-specific cell-seeded implants) yet the most simple and successful products to date are also the most uncomplicated: resorbable acellular extra-cellular matrices (ECMs) harve

8. Extra-cellular matrix changes in Schistosoma mansoni-infected Biomphalaria glabrata
Reactivity of snails against parasites exhibits a primitive focal reaction, with encapsulation, phagocytosis and destruction of parasite larvae by macrophage-like cells - the hemocytes. This reaction mimics granulomatous inflammation seen in higher animals. However, different from the latter, little is known about the participation of extra-cellular matrix i

9. Trypanosoma cruzi interaction with the extra-cellular matrix: modeling the TC85-11 protein and mapping the laminin-binding site / Trypanosoma cruzi e a interação com a matriz extracelular: modelagem da proteína Tc85-11 e determinação do sítio de ligação a laminina
Trypanosoma cruzi expresses the Tc85 proteins, a set of surface glycoproteins belonging to the gp85/trans-sialidase supergene family. In this report we show a structure model for Tc85-11 a member of this family, which has adhesive properties to laminin and to the host cell surfaces. That structure consists in an N-terminus β-propeller and a C-terminus &

10. Desenvolvimento do tendão elastico de aves : caracteristicas estruturais e aspectos ultra-estruturais relacionados a região elastica e a fibrocartilagem
Tendons are "usua11y suited for the transmission of mechanical forces from the musc1e of origin the bone of insertion. However, in many instances there are additionaI funCtiODS and properties difrering from the tendon ordinary anay, facing different biomechanical demands. The elastic tendon of the chicken wing has an elastic region that outspends to a large

11. Comportamento das celulas musculares lisas nos carcinomas da prostata humana : variações fenotipicas ultraestruturais
The smooth muscle cells of the human prostate were studied at the electron microscopy level from samples of radical prostatectomy in cases of prostate carcinomas. The smooth muscle cells are found in bundies, in which they are intimately associated to each other and with fused basement membrane. With the tumor progression, in the areas of glandular prolifera

12. Estudo imunocitoquimico das catepsinas D e B em celulas trofoblasticas gigantes de camundongos
The trophoblastic giant cells (TGC) differentiate from trophectoderm sheets or from the ectoplacental cone of mouse embryos and are committed to blastocyst implantation and placentation. It has attributed a high invasive capability and phagocytosis to the TGC which degenerate and remove the maternal tissues. However, the exact mechanism controlling their inv
