YAP activation promotes the transdifferentiation of cardiac fibroblasts to myofibroblasts in matrix remodeling of dilated cardiomyopathy

Braz. j. med. biol. res; 52 (1), 2019
Yes-associated protein (YAP) is an important regulator of cellular proliferation and transdifferentiation. However, little is known about the mechanisms underlying myofibroblast transdifferentiation in dilated cardiomyopathy (DCM). We investigated the role of YAP in the pathological process of cardiac ma...

Efeitos da arginina na reparação cicatricial da parede abdominal em ratos Wistar

Rev. Col. Bras. Cir; 46 (6), 2019
RESUMO Objetivo: avaliar os efeitos da arginina na cicatrização da parede abdominal de ratos Wistar. Métodos: vinte ratos Wistar foram submetidos à laparotomia e separados em dois grupos (arginina e controle), que receberam tratamento diário por via intraperitoneal com arginina (300mg/kg/dia) e so...

Effects of cyclosporin, nifedipine and phenytoin on gingival myofibroblast transdifferentiation in monkeys

J. appl. oral sci; 27 (), 2019
Abstract Objective: Myofibroblasts have been associated with the development of several pathologic fibrotic conditions. This longitudinal study aims to assess the proliferative and antiapoptotic effects of cyclosporin, nifedipine and phenytoin on gingival connective tissue cells of nonhuman primate, as ...

Diferenciação de miofibroblastos em feridas após uso tópico do metronidazol: estudo experimental

Rev. Col. Bras. Cir; 46 (1), 2019
RESUMO Objetivo: avaliar os efeitos da administração tópica do metronidazol na diferenciação de fibroblastos e na contração da ferida durante cicatrização experimental por segunda intenção em ratos. Métodos: cento e oito animais foram submetidos a uma ferida circular no dorso, com 2cm de di...

Healing effect of andiroba-based emulsion in cutaneous wound healing via modulation of inflammation and transforming growth factor beta 3

Acta cir. bras; 33 (11), 2018
Abstract Purpose: To evaluate the effects and mechanisms of andiroba-based emulsion (ABE) topical treatment on full-thickness cutaneous wounds in rats. Methods: The wounds were harvested on days 3, 7, 15, and 20 post-surgery. Wound contraction rate, quantitative immunohistochemistry [macrophages, myofi...

The influence of nicotine in healing of small bowel anastomoses in rats: angiogenesis and miofibroblasts

Rev. Col. Bras. Cir; 43 (2), 2016
ABSTRACT Objective: to know the effect of nicotine on angiogenesis and myofibroblast formation in anastomoses of the small bowel of rats. Methods: we randomly divided 60 Wistar rats into the groups Nicotine (N) and control (C), according to the proposed treatment. Each group was subdivided into three ...

Aplicação da mitomicina C na cirurgia refrativa

Rev. bras. oftalmol; 74 (6), 2015
RESUMO A mitomicina C teve seu uso profilático e terapêutico estabelecido, ao longo dos anos, para diminuir o haze depois da ablação superficial. A mitomicina C é segura e eficaz como uma terapia adjuvante aplicada após um procedimento primário de ceratectomia fotorrefrativa ou após um retratamen...
