SciELO - Scientific Electronic Library Online (52.285 recursos) SciELO (Scientific Electronic Library Online) is an electronic library covering a selected collection of Brazilian scientific journals. The objective of the site is to implement an electronic virtual library, providing full access to a collection of serial titles, a collection of issues from individual serial titles, as well as to the full text of articles. The project envisages the development of a common methodology for the preparation, storage, dissemination and evaluation of scientific literature in electronic format.
2. A new allele of peptidase-B in cattle - Lara,Maria Aparecida Cassiano; Contel,Eucleia Primo B. Electrophoretic analyses of peptidase-B were carried out on red cell hemolysates from Holstein, Mantiqueira and Gyr cattle, using cornstarch, known in Brazil as Penetrose-30.
6. Chromosome number in germplasm accessions of Paspalum notatum (Gramineae) - Pozzobon,Marisa T.; Valls,José Francisco M. Chromosome numbers are reported for 127 germplasm accessions of Paspalum notatum maintained by EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária) in two research centers in Brazil.
8. Callus induction and plant regeneration by Brazilian triticale and wheat genotypes - Dornelles,A.L.C.; Carvalho,F.I.F.; Federizzi,L.C.; Handel,C.L.; Bered,F.; Sordi,M.E.B.; Schneider,F. In order to determine the in vitro behavior of Brazilian triticale, 16 triticale genotypes, and three wheat genotypes used as checks, were sown in June 1994.
10. Genetic control of characters associated with bean golden mosaic geminivirus resistance in Phaseolus vulgaris L. - Pessoni,Luis Alberto; Zimmermann,Maria José de O.; Faria,Josias Corrêa de Seedlings of the four parents, six F1 hybrids, 12 backcrosses, and F2 generations for each combination were inoculated on the eighth day after sowing by exposure to a viruliferous whitefly (Bemisia tabaci Genn.) population for 24 h, in a glasshouse, prior to transplantation to field conditions.
12. Multivariate genetic divergence and hybrid performance of cacao (Theobroma cacao L.) - Dias,Luiz Antônio dos Santos; Kageyama,Paulo Yoshio Over a five-year period (1986-1990), five cultivars of the S1 generation, pertaining to the Lower Amazon Forastero and Trinitario racial groups and 20 crosses between the corresponding S0 parents were analyzed, based upon five yield components - number of healthy and collected fruits per plant (NHFP and NCFP), wet seed weight per plant and per fruit (WSWP and WSWF), and percentage of diseased fruits per plant (PDFP).
13. Mapping of a novel viviparous unstable mutant of maize (vp 12) - Araujo,Paula G.; Silva,William J. da; Maluf,Mirian P.; Prioli,Laudenir M. A new viviparous mutant of maize (Zea mays L.), associated with genetic instability and designated viviparous-12 (vp12), was identified in a synthetic Tuxpeño adapted to tropical regions.
14. Intra and interspecific variability of in vitro culture response in Lycopersicon (tomatoes) - Pratta,Guillermo; Zorzoli,Roxana; Picardi,Liliana Amelia Intra and interspecific variability was measured in the genus Lycopersicon for the traits: productivity rate (PR, total number of regenerated shoots/total number of cultures), regeneration percentage (%R, number of cultures regenerating shoots or primordia/total number of cultures) and callus percentage (%C, number of cultures only producing callus/total number of cultures).
15. Chromosome sensitivity to bleomycin in G2 lymphocytes from Down syndrome patients - Bartholomei-Santos,Marlise Ladvocat; Lucca,Edmundo José de Several studies have demonstrated that lymphocytes from patients with Down syndrome (DS) exhibit an increased frequency of chromosome aberrations when they are exposed to ionizing radiation or to chemicals at the G0 or G1 phases of the cell cycle, but not at G2, when compared to normal subjects.
16. Cytogenetic study of 50 Brazilian patients with primary myelodysplastic syndrome - Fernandez,Teresa de Souza; Silva,Maria Luiza M.; Souza,Jamison M. de; Tabak,Daniel; Abdelhay,Eliana Patients with refractory anemia, or refractory anemia with ringed sideroblasts, presented normal karyotypes or single abnormalities such as del(5q) or -Y, while patients with refractory anemia with an excess of blasts, refractory anemia with an excess of blasts in transformation or chronic myelomonocytic leukemia showed complex karyotypes and single abnormalities involving chromosomes 7 or 8, which are related to a bad prognosis and an elevated risk of evolution to acute myeloid leukemia.
17. Family names and the length of the Y chromosome in Brazilian blacks - Barbosa,Ana A.L.; Cavalli,Iglenir J.; Abé,Kiyoko; Santos,Maria G.; Azevêdo,Eliane S. The variability of the lengths of the heterochromatic and euchromatic segments of the human Y chromosome was studied by a quantitative method of densitometric measurement in 60 normal and unrelated black individuals (30 with and 30 without devotional surnames), living in Salvador, Bahia, northeastern Brazil.
