Fenômeno de Marcus Gunn recidivado: relato de caso e revisão bibliográfica

Rev. bras. cir. plást; 29 (4), 2014
INTRODUÇÃO: O fenômeno de Marcus Gunn é uma ptose congênita rara e pouco conhecida, de origem neurogênica, de fisiopatogenia ainda não esclarecida. Os autores relatam um caso de ptose acentuada e recidivada após quatro correções cirúrgicas, e fazem uma breve revisão bibliográfica. RELATO DE ...

Mastoplastia redutora associada a implante de silicone: quando indico?

Rev. bras. cir. plást; 29 (4), 2014
Introdução: Insatisfação dos pacientes com resultado de mamoplastia redutora pode ser identificado em alguns casos, especialmente quando apresentam ptose acompanhada de flacidez excessive, estrias, e ainda, componente mamário mais gorduroso que glandular. Nesses tipos de pacientes, é muito difícil...

Reconstrução mamária com TRAM: uma técnica alternativa para o fechamento do defeito abdominal

Rev. bras. cir. plást; 29 (4), 2014
INTRODUÇÃO: O retalho do músculo reto abdominal, descrito por Drever em 1977, foi posteriormente modificado e, desde então, se tornou rapidamente uma importante alternativa para reconstrução da mama. Dentre as complicações do TRAM, citam-se os abaulamentos e hérnias abdominais na área doadora. ...

Reconstrução da parede torácica após a ressecção de extensos tumores

Rev. bras. cir. plást; 29 (4), 2014
INTRODUÇÃO: Nos estágios finais da reconstrução torácica, consequente a exéreses tumorais, são necessários procedimentos complexos e implantes. O que requer cuidados multidisciplinares, com a participação dos cirurgiões torácicos, plástico, radiologista e fisioterapeuta. O objetivo foi desc...

Study on vascular endothelial growth factor and its receptor in the vitreous of diabetic rats

West Indian med. j; 62 (9), 2013
OBJECTIVE: To investigate the vitreous level of vascular endothelial growth factor (VEGF) and kinase insert domain-containing receptor (KDR) in diabetic rats, and to explore the role of VEGF and KDR in diabetic retinopathy. METHODS: Eighty-four adult Wistar rats were randomly divided into two groups. Fif...

Role of interleukin-6, gamma interferon and adenosine deaminase markers in management of pleural effusion patients

West Indian med. j; 62 (9), 2013
OBJECTIVE: Pleural effusion is a common diagnostic and clinical problem. Neoplasms and tuberculosis are the most frequent diagnostic causes of such effusions. Conventional laboratory methods for diagnosis of such effusion are inefficient because tubercle bacilli are rarely seen in direct examinations of ...

Profiling carbohydrate composition, biohydrogen capacity, and disease resistance in potato

Electron. j. biotechnol; 16 (6), 2013
Background: Potato (Solanum tuberosum) is one of the most important sources of carbohydrates in human diet. Because of its high carbohydrate levels it recently has also received attention in biohydrogen production. To exploit the natural variation of potato with respect to resistance to major diseases, c...

Immobilization of cyclodextrin glucanotransferase on aminopropyl-functionalized silica-coated superparamagnetic nanoparticles

Electron. j. biotechnol; 16 (6), 2013
Background: Cyclodextrin glycosyltransferase (CGTase) from Amphibacillus sp. NPST-10 was successfully covalently immobilized on aminopropyl-functionalized silica coated superparamagnetic nanoparticles; and the properties of immobilized enzyme were investigated. The synthesis process included preparing of...

Evaluation of the hypoglycaemic activity of Petiveria alliacea (Guinea Hen Weed) extracts in normoglycaemic and diabetic rat models

West Indian med. j; 62 (8), 2013
OBJECTIVE: Petiveria alliacea (p alliacea) has ethno-traditional use as a hypoglycaemic agent in Jamaica and is yet to be scientifically validated as such. Therefore, extracts of aerial parts of the plant were evaluated for hypoglycaemic activity in normoglycaemic and diabetic rats. METHODS: Aqueous and ...
