231 Laparoscopic Cholecystectomy in Ambulatory: What Results?
Goulart, André; Serviço de Cirurgia Geral. Hospital de Braga. Braga. Portugal.Introduction: Laparoscopic cholecystectomy is the gold standard procedure for the treatment of lithiasic gallblader pathology and acute cholecystitis. Whether or not it should be done as ambulatory surgery is still being discussed. The present study aims to analyze the quality and safety of laparoscopic cholecystectomy conducted by the Ambulatory Unit of Hospital de Braga and compare the results with those from...
Rye Bs disclose ancestral sequences in cereal genomes with a potential role in ...
Pereira, H. Sofia; Barão, Augusta; Caperta, A.; Rocha, João; Viegas, Wanda; Delgado, MargaridaResearch Article ; Two sequence families, E3900 and D1100, are amplified on the subtelomeric domain of the long arm of rye B chromosomes, the region that controls its drive mechanism. In this work, polymerase chain reaction (PCR) with a number of primers spanning E3900 shows that the organization and nucleotide sequence of E3900-related portions are present and highly conserved on rye A chromosomes as well as ...
Interplay of ribosomal DNA Loci in nucleolar dominance: dominant NORs are up-re...
Silva, Manuela; Viegas, Wanda; Pereira, H. Sofia; Bento, Miguel; Santos, Ana Paula; Shaw, Peter; Delgado, Margarida; Neves, NunoBackground: Chromatin organizational and topological plasticity, and its functions in gene expression regulation, have been strongly revealed by the analysis of nucleolar dominance in hybrids and polyploids where one parental set of ribosomal RNA (rDNA) genes that are clustered in nucleolar organizing regions (NORs), is rendered silent by epigenetic pathways and heterochromatization. However, information on the...
Transcriptionally active heterochromatin in rye B chromosomes
Carchilan, Mariana; Delgado, Margarida; Ribeiro, Teresa; Nunes, Pedro Costa; Caperta, A.; Morais-Cecílio, L.; Jones, R. Neil; Viegas, WandaB chromosomes (Bs) are dispensable components of the genomes of numerous species. Thus far, there is a lack of evidence for any transcripts of Bs in plants, with the exception of some rDNA sequences. Here, we show that the Giemsa bandingpositive heterochromatic subterminal domain of rye (Secale cereale) Bs undergoes decondensation during interphase. Contrary to the heterochromatic regions of A chromosomes, this...
Avaliação dos recursos hospitalares para assistência perinatal em Belo Horizont...
Costa,José Orleans; Xavier,César Coelho; Proietti,Fernando Augusto; Delgado,Margarida SOBJETIVO: Verificar a adequação de recursos hospitalares no atendimento às gestantes/neonatos, no ano de 1996. MÉTODOS: Trata-se de um estudo transversal abrangendo 28 hospitais-maternidade em funcionamento no município de Belo Horizonte, MG. Utilizou-se um modelo de avaliação denominado "níveis de complexidade e segurança em potencial de unidades perinatais de hospitais-maternidade", elaborado a partir da aval...
Variability of soybean germplasm in relation to phosphorus uptake and use effic...
Furlani,Ângela Maria Cangiani; Furlani,Pedro Roberto; Tanaka,Roberto Tetsuo; Mascarenhas,Hipólito Assunção Antonio; Delgado,Margarida das Dores PaesPlant efficiency for phosphorus uptake and utilization may contribute to improve crop yield potential in situations of low P availability. Twenty nine soybean [Glycine max (L.) Merr.] cultivars were evaluated and classified in relation to the response to phosphorus (P) levels in nutrient solution. P uptake and use efficiency were estimated by the variables: shoot and root dry matter (DM) yield, P-concentrations...
