13. Trajetória de crescimento no Sistema de Crédito Cooperativo SICREDI : autoperpetuação e autodestruição
This Research has the objective of describing the growth trajectory and to identify indicators for the self-perpetuation or self-destruction noticed in the Credit Cooperative System ¿ SICREDI, which is now in 10 states in Brazil, with its headquarters in Porto Alegre, RIO GRANDE DO SUL State, from 1980 up to 2010, from its strategic decisions. For this reas

14. NOTICING E CONSCIOUSNESS-RAISING NA AQUISIÇÃO DA ESCRITA EM LÍNGUA MATERNA / NOTICING AND CONSCIOUSNESS-RAISING IN THE ACQUISITION OF WRITING IN MOTHER TONGUE
The competence in textual production and the consciousness about this process must reflect the work done in teacher training courses, in order to prepare them not only to be producers of text, but mostly to become good mediators of this activity. From this finding, it was determined the main problem of this thesis: how did the Letras freshman develop the met

15. Renovação Carismática Crioula: uma leitura do papel do animador litúrgico na Renovação Carismática Católica em Juiz de Fora sob a luz de Sacrosanctum Concilium 37-39
This dissertation aims to investigate the mechanisms of liturgical adaptation happening on the Roman Catholic Church in Brazil using a punctual investigation of the Commentator (or Animator) liturgical function on the location of Juiz de Fora MG, inserted on the ecclesial context known as Renovação Carismática Católica (a local translation and adaptation

16. O ser-tempo em Dogen e a educação transdisciplinar.
This research is constituted as a narrative of a path where we have walked through a hermeneutics in which body and mind are implied, theoretical and practical aspects, as part of an effort towards a self knowledge by the reading of the text. The thought of Eihei Dogen goes back to the XIII century, in the context of a medieval Japan, but his ideas have only

17. Effect of conditioned medium of mesenchymal stem cells on the in vitro maturation and subsequent development of mouse oocyte
Mesenchymal stem cells (MSCs) secrete a variety of cytokines and growth factors in addition to self-renewal and multiple forms of differentiation. Some of these secreted bioactive factors could improve meiotic maturation in vitro and subsequent embryo developmental potential. The aim of the present study was to determine whether in vitro maturation (IVM) of

18. Estudo da proliferação e diferenciação de células-tronco hematopoéticas provenientes de sangue de cordão umbilical na presença e ausência de mitógenos. / Proliferation and differentiation study of hematopoetic stem cells from umbilical cord blood in the presence and absence of mitogens.
Hematopoietic stem cells (HSC) from umbilical cord blood (UCB) have a great potencial for hematopoietic reconstitution. Although these stem cells have been well characterized by their functional and fenotipics properties, self-renewal regulation and genes involved are still unknown. Analyses of cell growth, clonogenic assay and flow cytometry revealed the ex

19. Identification of differentialy express genes during the differentiation of stem cells and characterization of mesenchymal progenitor cells / Identificação de genes diferencialmente expressos durante diferenciação de células-tronco e caracterização de células progenitoras mesenquimais
Diabetes mellitus (DM) defines a number of pathologies caused by the lack or deficient action of the insulin hormone. DM1 is caused by an auto-immune attack to insulin secreting β-pancreatic cells, while DM2 is related to ageing and obesity. Pancreas and islet allo-transplantation constitute therapeutic alternatives, but severe organ shortage and the ab

20. THE POPULAR SOLIDARY ECONOMY FRONT TO THE CONTEMPORANY TRANSFORAMATIOS IN THE WORLD OF THE WORK / A ECONOMIA POPULAR SOLIDÁRIA FRENTE ÀS TRANSFORMAÇÕES CONTEMPORÂNEAS NO MUNDO DO TRABALHO
The present work treats the recent process of transformations, many of them still in course, in the capitalist s way of production and of the formation of the popular solidary economy in Brazil starting from the years of 80s. The importance of approaching these themes in part starting from the critical reality of exploration and hesitation of the life condit

21. Redox state is a central modulator of the balance between self-renewal and differentiation in a dividing glial precursor cell
We have discovered that intracellular redox state appears to be a necessary and sufficient modulator of the balance between self-renewal and differentiation in dividing oligodendrocyte-type-2 astrocyte progenitor cells. The intracellular redox state of freshly isolated progenitors allows prospective isolation of cells with different self-renewal characterist

22. JAK2, complemented by a second signal from c-kit or flt-3, triggers extensive self-renewal of primary multipotential hemopoietic cells
Defining signals that can support the self-renewal of multipotential hemopoietic progenitor cells (MHPCs) is pertinent to understanding leukemogenesis and may be relevant to developing stem cell-based therapies. Here we define a set of signals, JAK2 plus either c-kit or flt-3, which together can support extensive MHPC self-renewal. Phenotypically and functio

23. Proliferative capacity of murine hematopoietic stem cells.
The present study demonstrates a decrease in self-renewal capacity with serial transfer of murine hematopoietic stem cells. Production of differentiated cell progeny is maintained longer than stem cell self-renewal. In normal animals the capacity for self-renewal is not decreased with increasing donor age. The stem cell compartment in normal animals, both yo

24. Evidence for structured variation in self-renewal capacity within long-term bone marrow cultures.
Bone marrow pluripotent stem cells (CFUs) demonstrate capacity for both proliferation and differentiation. The proliferative capacity of CFUs has been measured by serial transplantability and by the Rs, a measurement of CFU production in a single 14-day transfer. In the present study, the self-renewal capacity fo both adherent and nonadherent CFUs from long-
