Low-dose paclitaxel modulates the cross talk between the JNK and Smad signaling in primary biliary fibroblasts

SUMMARY OBJECTIVE: The objective of this study was to explore the molecular mechanism underlying the occurrence of benign bile duct stricture and the target of low-dose paclitaxel in the prevention of benign bile duct stricture. METHODS: Under the stimulation of transforming growth factor beta 1, the e...

Effects of Physical Training on the Myocardium of Oxariectomized LDLr Knockout Mice: MMP 2/9, Collagen I/III, Inflammation and Oxidative Stress

Arq. bras. cardiol; 114 (1), 2020
Abstract Background: The emergence of coronary heart disease is increased with menopause, physical inactivity and with dyslipidemia. Physical training is known to promote the improvement of cardiovascular functions. Objective: To investigate the effects of aerobic physical training on the left ventricl...

Expression of specificity protein 1 and collagen I in primary pterygial tissues

Arq. bras. oftalmol; 82 (5), 2019
ABSTRACT Purpose: To determine the expression profiles of the transcription factor specificity protein 1 and collagen I in primary pterygial and normal conjunctival tissues, and to explore the role of specificity protein 1 and collagen I in pterygial development. Methods: The pterygial tissues of 20 pa...

Prediction of bone mass changes after successful parathyroidectomy using biochemical markers of bone metabolism in primary hyperparathyroidism: is it clinically useful?

ABSTRACT Objective To measure type 1 serum amino-terminal propeptide procollagen (P1NP) and type 1 cross-linked C-terminal telopeptide collagen (CTX) before parathyroidectomy (PTX) in PHPT patients, correlating these measurements with bone mineral density (BMD) changes. Subjects and methods 31 primar...

Notum attenuates HBV-related liver fibrosis through inhibiting Wnt 5a mediated non-canonical pathways

Biol. Res; 52 (), 2019
BACKGROUND: Non-canonical Wnt pathways play important roles in liver fibrosis. Notum is a newly discovered inhibitor to Wnt proteins. This study was to investigate anti-fibrotic effects of Notum. METHODS: 53 patients with hepatitis B virus (HBV) infection as well as a cell co-culture system of LX-2 and H...

Fluorofenidone inhibits apoptosis of renal tubular epithelial cells in rats with renal interstitial fibrosis

Braz. j. med. biol. res; 52 (11), 2019
This study aimed to investigate the mechanism of fluorofenidone (AKF-PD) in treating renal interstitial fibrosis in rats with unilateral urinary obstruction (UUO). Thirty-two male Sprague-Dawley rats were randomly divided into sham, UUO, UUO + enalapril, and UUO + AKF-PD groups. All rats, except sham, un...

Effects of the application of the amniotic membrane in the healing process of skin wounds in rats

Acta cir. bras; 33 (2), 2018
Abstract Purpose: To evaluate the efficacy of the application of the human amniotic membrane (HAM) on the inflammatory process, fibroblast proliferation, formation of collagenand reduction of skin wound areas in rats. Methods: Thirty six rats were submitted to a surgical injury induction and divided ...

Effects of renal dysfunction on healing of colonic anastomosis: experimental study in wistar rats

ABCD (São Paulo, Impr.); 31 (4), 2018
ABSTRACT Background: Chronic kidney disease affects more than 500 million people worldwide. In this context, the uremic toxins present are related to worsening in tissue healing. Aim: Evaluate on healing of colonic anastomosis in uremic rats, serum and anatomopathological indicators, which may be rela...

MicroRNA-98 inhibits the cell proliferation of human hypertrophic scar fibroblasts via targeting Col1A1

Biol. Res; 50 (), 2017
BACKGROUND: Hypertrophic scarring (HS) is a severe disease, and results from unusual wound healing. Col1A1 could promote the hypertrophic scar formation, and the expression of Col1A1 in HS tissue was markedly higher than that in the normal. In present study, we aimed to identify miRNAs as post-transcript...

Characteristics of the fibroplasia and collagen expression in the abdominal wall after implant of the polypropylene mesh and polypropylene/polyglecaprone mesh in rats

Acta cir. bras; 31 (5), 2016
ABSTRACT PURPOSE: To compare fibroplasia and the resistance of the abdominal wall when polypropylene meshes and polypropylene/poliglecaprone are used. METHODS: Seventy-seven male Wistar rats were divided into three groups: Control Group (for resistance); Group E (polypropylene mesh); and Group U (polyp...
