The role of sequence duplication in transcriptional regulation and genome evolution
(Bentham Science Publishers, 2019-01-24)
Sequence duplication is nowadays recognized as an important mechanism that underlies the evolution of eukaryote genomes, being indeed one of the most powerful strategies for the generation of adaptive diversity by modulating ...
Esophageal duplication: a case report
(2010)
Se presenta el caso de una lactante de 11 meses con antecedentes de reflujo gastroesofágico y hernia hiatal que ingresa electivamente a la Sección de Cirugía Pediátrica, con el objetivo de realizar una fundoplicatura de ...
Cecal duplication causing a disappearing abdominal mass in an infant
(W B Saunders Co, 2001-10-01)
Duplications of the alimentary tract are rare malformations. A case of a 2-year-old girl with an intestinal intussusception caused by a cystic duplication of the cecum is presented. This case report is justified by its ...
Polymelia and duplication of the descending colon in a Poodle dog - a case report
(Univ Zagreb Vet Faculty, 2018-01-01)
This study describes a six-month old female Poodle dog born with a third hind limb and duplication of the descending colon. The extra limb was projected dorsally toward the coccygeal vertebrae and was slightly displaced ...
Multiple independent origins of mitochondrial control region duplications in the order Psittaciformes
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012-08)
mitochondrial genomes are generally thought to be under selection for compactness, due to their small size, consistent gene content, and a lack of introns or intergenic spacers. As more animal mitochondrial genomes are ...
Optimal design of multiproduct batch plants considering duplication of units in series
(Institution of Chemical Engineers, 2009-11)
A generalized disjunctive programming (GDP) model for the optimal design of multiproduct batch plants is presented. This general model manages the duplication of units in series to perform a given operation in the process, ...
Non-mosaic partial duplication 12p in a patient with dysmorphic characteristics and developmental delay
(2020-01-01)
Duplication of the short arm of chromosome 12 is a rare chromosomal abnormality that may arise de novo or result from malsegregation of a balanced parental translocation. This study comprises the clinical description, ...
Subfunctionalization reduces the fitness cost of gene duplication in human by buffering dosage imbalances
(BioMed Central, 2011-12)
Background
Driven essentially by random genetic drift, subfunctionalization has been identified as a possible non-adaptive mechanism for the retention of duplicate genes in small-population species, where widespread ...
