Interest in astroglial cells is rising due to recent findings supporting dynamic neuron-astrocyte interactions. There is increasing evidence of astrocytic dysfunction in several brain disorders such as depression, schizophrenia or bipolar disorder; importantly these pathologies are characterized by the involvement of the prefrontal cortex and by significant(More)
Data from surnames and racial subgroups were obtained in 60 localities to reconstruct the history of population spread and mixing over the state of Bahia, Brazil. Using the historically significant location of Cachoeira and Sao Felix as central points, the sampled localities were distributed along 7 main paved roads. 20% of the elementary school children(More)
The ongoing racial admixture was studied in the island of Itaparica off the coast of the State of Bahia, in Brazil. The following gene frequencies were observed: Hb S = 0.039; Hb C = 0.022; PGD C = 0.024; Gd A = 0.217 and Gd A = 0.052, among 293 mixed school children whose black phenotype index (medium mulatto + dark mulatto + black/total) was 0.457. Data(More)
The effects of ABO blood groups and black admixture on the level of factor VIII:C are studied in healthy adults from Salvador, Bahia, Brazil. A racially mixed sample of 125 males was selected as follows: 25 whites, 25 light mulattoes, 25 medium mulattoes, 25 dark mulattoes, and 25 blacks. Levels of both factor VIII:C and K-PTT followed normal distributions.(More)
Human aconitase (ACONS) polymorphism was studied in three samples from northeastern Brazil. Two of the samples were collected in the State of Bahia and one in the State of Sergipe. The main characteristic of the samples was given by different degrees of Black admixture. The results showed that the more negroid the samples the higher the frequencies of the(More)
The long median survival time of patients with follicular non-Hodgkin's lymphoma (NHL), means that the efficacy of new treatments are difficult to assess in the short term. Bcl-2 is an inhibitor of apoptosis and overexpression of the bcl-2 gene in the blood or bone marrow is a feature in up to 85% of patients with follicular NHL. Levels of bcl-2(+) cells in(More)
PGM3 polymorphism was studied in 301 placenta samples from the Negroid population of Northeastern Brazil. The following gene frequencies were encountered: PGM3*1 = 0.545 and PGM3*2 = 0.455. They lie between European and African gene frequencies. The prevalent Black and White admixture of Northeastern Brazil populations fits well with the observed gene(More)
