    • Annexin 1 localisation in tissue eosinophils as detected by electron microscopy 

      Oliani, Sonia Maria [UNIFESP]; Damazo, Amilcar Sabino [UNIFESP]; Perretti, M. (Hindawi Publishing Corporation, 2002-10-01)
      BACKGROUND: Human and rodent leukocytes express high levels of the glucocorticoid-inducible protein annexin 1 ( ANXA1) ( previously referred to as lipocortin 1). Neutrophils and monocytes have abundant ANXA1 levels.Aim: ...

    • Cell death and regeneration in the midgut of the mosquito, Culex quinquefasciatus 

      Okuda, Kendi; Almeida, Fabio de; Mortara, Renato A.; Krieger, Henrique; Marinotti, Osvaldo; Bijovsky, A. Tania (Elsevier B.V., 2007-12-01)
      Haematophagy, the utilization of blood as food, has evolved independently among insects such as mosquitoes, bedbugs, fleas, and others. Accordingly, several distinct biological adaptations have occurred in order to facilitate ...

    • Centronuclear myopathy: histopathological aspects in ten patients with chilfhood onset 

      Zanoteli, Edmar [UNIFESP]; Oliveira, Acary Souza Bulle [UNIFESP]; Kiyomoto, Beatriz Hitomi [UNIFESP]; Schmidt, Beny [UNIFESP]; Gabbai, Alberto Alain [UNIFESP] (Academia Brasileira de Neurologia - ABNEURO, 1998-03-01)
      Centronuclear myopathy is a rare congenital myopathy. According to the period of onset of signs and symptoms and the degree of muscular involvement three clinical forms are distinguished: severe neonatal; childhood onset; ...

    • Chondroitin sulfate proteoglycans are structural renewable constituents of the rabbit vitreous body 

      Goes, Rejane M.; Nader, Helena Bonciani [UNIFESP]; Porcionatto, Marimélia Aparecida [UNIFESP]; Haddad, Antonio; Laicine, Eduardo M. (Taylor & Francis Inc, 2005-05-01)
      Purpose: To characterize the vitreous intrinsic proteoglycans, investigate their dynamics, and examine their role in the supramolecular organization of the vitreous. Methods: Vitreous from normal rabbits was collected and ...

    • Colocalization of heparin and histamine in the intracellular granules of test cells from the invertebrate Styela plicata (Chordata-Tunicata) 

      Cavalcante, MCM; Andrade, L. R. de; Santos-Pinto, C. D.; Straus, A. H.; Takahashi, H. K.; Allodi, S.; Pavao, MSG (Elsevier B.V., 2002-03-01)
      In most ascidian species the oocytes are surrounded by two types of accessory cells called follicle cells and test cells. Test cells are located on the periphery of oocytes and remain in the perivitelline space during egg ...

    • Comparison of Fonsecaea pedrosoi sclerotic cells obtained in vivo and in vitro: ultrastructure and antigenicity 

      Silva, Jorge Pereira da; Alviano, Daniela Sales; Alviano, Celuta Sales; Souza, Wanderley de; Travassos, Luiz Rodolpho [UNIFESP]; Diniz, José Antonio Picanço; Rozental, Sonia (Elsevier B.V., 2002-03-25)
      The parasitic form of Fonsecaea pedrosoi from the hyperkeratotic layer of the skin was obtained from four patients with chromoblastomycosis. Primary cultures containing hyphae and conidia were successfully converted into ...

    • Development of granulocytes in haematopoietic tissues of Rhizoprionodon lalandii 

      Pacheco, F. J.; Pacheco, SOS; Segreto, HRC; Segreto, R. A.; Silva, MRR; Egami, Mizue Imoto [UNIFESP] (Elsevier B.V., 2002-10-01)
      Granulocytes of the epigonal and Leydig organs of Rhizoprionodon lalandii were identified and classified into three different cell types, type I and type II eosinophils and neutrophils. the development of these cells in ...

      Arana-Chavez, V. E.; Katchburian, Eduardo [UNIFESP] (Munksgaard Int Publ Ltd, 1998-01-01)
      We have examined freeze-fracture replicas of maxillary first molar tooth germs of newborn rat at early stages of dentinogenesis to study the development of tight junctions in the distal plasma membrane of differentiating ...
