1. Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats
Abstract Reports have indicated that serotonin plays an important role in cell migration and differentiation during the organogenesis of several tissues, including the oral types. Administration of selective serotonin reuptake inhibitor (SSRI) drugs during pregnancy could affect the delivery of serotonin to embryonic tissues altering its development. Object

2. La Innovación y la Migración calificada en la Encrucijada: Reflexiones a partir de la Experiencia Mexicana
Abstract Skilled migration is analyzed through an analytical framework that so far has been essentially ignored in the specialized literature on the subject: the deep restructuration process to which innovation systems have been subjected under the context of neoliberal globalization and the leadership of the United States. Besides unraveling the main transf

3. Tetrasomy 3q26.32-q29 due to a supernumerary marker chromosome in a child with pigmentary mosaicism of Ito
Abstract Pigmentary mosaicism of Ito (PMI) is a skin abnormality often characterized by hypopigmentation of skin, following, in most cases, the Blaschko lines, usually associated with extracutaneous abnormalities, especially abnormalities of the central nervous system (CNS). It is suggested that this pattern arises from the presence and migration of two cell

4. Effect of follicular fluid supplementation during in vitro maturation on total cell number in bovine blastocysts produced in vitro
This study evaluated the influence of follicular fluid (FF) added to the maturation medium on the quality of bovine embryos produced in vitro. In the first experiment, oocytes were matured in media containing five different FF concentrations with different maturation times and classified according to meiotic progression and migration of cortical granules. In

5. AvaliaÃÃo do potencial antitumoral e antiangiogÃnico de novos anÃlogos ftalimÃdicos da talidomida / EVALUATION OF THE ANTITUMOR AND ANTIANGIOGENIC POTENTIAL OF NEW FTHALIMIDES THALIDOMIDE ANALOGUES
The thalidomide was previously used to relieve gastric discomforts during pregnancy, and currently it is used for cancer treatment and inflammatory illnesses. Various phthalimides analogues of thalidomide have been researched for its antiangiogenic and immunemodulatory activity. In previous studies, these analogues showed absence of immunesuppressor activity

6. CCN2/CTGF silencing blocks cell aggregation in embryonal carcinoma P19 cell
Connective tissue growth factor (CCN2/CTGF) is a matricellular-secreted protein involved in extracellular matrix remodeling. The P19 cell line is an embryonic carcinoma line widely used as a cellular model for differentiation and migration studies. In the present study, we employed an exogenous source of CCN2 and small interference RNA to address the role of

7. Expression of beta 2 integrin (CD18) in embryonic mouse and chicken heart
Integrins are heterodimeric receptors composed of α and β transmembrane subunits that mediate attachment of cells to the extracellular matrix and counter-ligands such as ICAM-1 on adjacent cells. β2 integrin (CD18) associates with four different α (CD11) subunits to form an integrin subfamily, which has been reported to be expressed exclusively on leukoc

8. Emprego tópico de prostaglandina da família E ou de análogo com o intuito de acelerar a migração de embriões eqüinos para o útero e imunolocalização dos respectivos receptores / Topic application of prostaglandin E family or analogous aiming the acceleration of the migration of equine embryos to the uterus and immunolocalization of the respective receptors
Differently of any other ways of occurrence among the domestic animals, concerning mares, their embryos migrate in a delayed lapse of time to their uterus due to a correlation to the PGE2. Consequently, one extracts embryos which are already into some more advanced phase of their development (blastocyst and expanded blastocyst) normally exceeding 300 microme

9. Analysis of P2X2 e P2X4 receptors during neuronal differentiation / Análise dos receptores P2X2 e P2X4 durante a diferenciação neuronal
During the development of the nervous system, oscillations of intracellular calcium concentrations activate programs of gene expression resulting in proliferation, migration and neuronal differentiation of embryonic cells. In this thesis, the participation of ionotropic P2X2 and P2X4 receptor subtypes, whose receptor channels are highly permeable for calcium

10. The extracellular matrix provides directional cues for neuronal migration during cerebellar development
Normal central nervous system development relies on accurate intrinsic cellular programs as well as on extrinsic informative cues provided by extracellular molecules. Migration of neuronal progenitors from defined proliferative zones to their final location is a key event during embryonic and postnatal development. Extracellular matrix components play import

12. Distribution of microglial cells in the cerebral hemispheres of embryonic and neonatal chicks
The distribution, morphology and morphometry of microglial cells in the chick cerebral hemispheres from embryonic day 4 (E4) to the first neonatal day (P1) were studied by histochemical labeling with a tomato (Lycopersicon esculentum) lectin. The histochemical analysis revealed lectin-reactive cells in the nervous parenchyma on day E4. Between E4 (5.7 ± 1.3
