Genomic constellations of RVA detected in Brazil from 1986 to 2016: a temporal and geographical distribution and occurrence of reassortments

ABCS health sci; 48 (), 2023
INTRODUCTION: Species A rotavirus (RVA) infections are a major cause of severe gastroenteritis in children of <5 years worldwide. In Brazil, before vaccination, RVA was associated with 3.5 million episodes of acute diarrheal disease per year. Due to the segmented nature of their genomes, rotaviruses can ...

Inversiones cromosómicas (anomalías estructurales poco frecuentes) asociadas a fenotipo normal, dudoso y patológico

Prensa méd. argent; 104 (10), 2018
Las inversiones son reordenamientos intracromosómicos originados por dos rupturas en un cromosoma seguidas de la reinserción del fragmento rotado en 180º. Dependiendo si involucra o no al centrómero pueden ser pericén tricas o paracéntricas. La incidencia es 0.09 a 0.49/1.000. Las inversiones son r...

A pioneering RET genetic screening study in the State of Ceará, Brazil, evaluating patients with medullary thyroid cancer and at-risk relatives: experience with 247 individuals

ABSTRACT Objective: Initial diagnosis of medullary thyroid carcinoma (MTC) is frequently associated with advanced stages and a poor prognosis. Thus, the need for earlier diagnoses and detection in relatives at risk for the disease has led to increased use of RET genetic screening. Subjects and methods:...

Minimal residual disease detection in Tunisian B-acute lymphoblastic leukemia based on immunoglobulin gene rearrangements

Braz. j. med. biol. res; 50 (1), 2017
IGH gene rearrangement and IGK-Kde gene deletion can be used as molecular markers for the assessment of B lineage acute lymphoblastic leukemia (B-ALL). Minimal residual disease detected based on those markers is currently the most reliable prognosis factor in B-ALL. The aim of this study was to use clona...

Immunoglobulin heavy chain gene rearrangement in non B-cell haematological malignancies

West Indian med. j; 62 (8), 2013
PURPOSE: Clonality detection through amplifying immunoglobulin heavy chain (IGH) gene rearrangements by polymerase chain reaction (PCR) is a useful tool in diagnosis of various B-lymphoid malignancies. Immunoglobulin heavy chain gene rearrangement can be an optimal target for clonality detection in B-lym...

Chemical transformations of neolignans

Mem. Inst. Oswaldo Cruz; 86 (supl.2), 1991
Neolignans, generated by oxydative dimerization of propenylphenol and/or allylphenol, undergo further modifying steps. These biosynthetic reactions, confirmed in vitro, include Cope, retro-Claisen and Claisen rearrangements. Additionally acid catalysis effects convertions of bicyclo [3.2.1] octanoid neol...
