Dionisio,Fernando Carrasco Ferreira; Oliveira,Larissa Santos; Hernandes,Mateus de Andrade; Engel,Edgard Eduard; Azevedo-Marques,Paulo Mazzoncini deAbstract Objective: To evaluate the degree of similarity between manual and semiautomatic segmentation of soft-tissue sarcomas on magnetic resonance imaging (MRI). Materials and Methods: This was a retrospective study of 15 MRI examinations of patients with histopathologically confirmed soft-tissue sarcomas acquired before therapeutic intervention. Manual and semiautomatic segmentations were performed by three ...
Perineal trauma after vaginal delivery in healthy pregnant women
Oliveira,Larissa Santos; Brito,Luiz Gustavo Oliveira; Quintana,Silvana Maria; Duarte,Geraldo; Marcolin,Alessandra CristinaCONTEXT AND OBJECTIVE:Despite all the medical care provided during delivery labor, perineal injury is still prevalent and may lead to diverse pelvic floor disorders. The aim here was to investigate the prevalence of obstetric and anal sphincter injuries (OASIS) in healthy pregnant women after vaginal delivery.DESIGN AND SETTING:Cross-sectional study involving 3,034 patients with singletons in a secondary hospit...
Genetic diversity between improved banana diploids using canonical variables an...
Pereira,Valquíria Martins; Borges,Cristine Vanz; Brandão,Lívia Pinto; Oliveira,Larissa Santos; Souza,Cintia Paula Feitosa; Gonçalves,Zalmar SantanaThe objective of this work was to estimate the genetic diversity of improved banana diploids using data from quantitative analysis and from simple sequence repeats (SSR) marker, simultaneously. The experiment was carried out with 33 diploids, in an augmented block design with 30 regular treatments and three common ones. Eighteen agronomic characteristics and 20 SSR primers were used. The agronomic characteristi...
