Cyclosporine A impairs bone repair in critical defects filled with different osteoconductive bone substitutes

Abstract The aim of this study was to assess the influence of cyclosporine administration on the repair of critical-sized calvaria defects (CSDs) in rat calvaria filled with diverse biomaterials. Sixty animals were divided into two groups: the control (CTR) group (saline solution) and the cyclosporine (C...

Effect of ScLL and 15d-PGJ2 on viability and cytokine release in LPS-stimulated fibroblasts: an in vitro study

Abstract This study evaluated the effect of a cyclopentenone-type PG, 15-Deoxy-Δ12,14-PG J2 (15d-PGJ2), and lectin (ScLL) on the viability of human gingival fibroblasts (HGFs), and on IL-6 and TGFβ-1 release by these fibroblasts, stimulated with lipopolysaccharide (LPS). HGFs were stimulated wi...

Morphometric and molecular muscle remodeling after passive stretching in elderly female rats

Clinics; 75 (), 2020
OBJECTIVES: To determine the effects of three sessions of a passive stretching exercise protocol on the muscles of elderly female rats. METHODS: The effects of the stretching exercises on the soleus muscle were analyzed using immunohistochemistry [tissue inhibitors of matrix metalloproteinases (TIMP), t...

Estrogen attenuates TGF-β1-induced EMT in intrauterine adhesion by activating Wnt/β-catenin signaling pathway

Braz. j. med. biol. res; 53 (8), 2020
Although estrogen has crucial functions for endometrium growth, the specific dose and underlying molecular mechanism in intrauterine adhesion (IUA) remain unclear. In this study, we aimed to investigate the effects of estrogen on epithelial-mesenchymal transition (EMT) in normal and fibrotic endometrium,...

The overexpression of lncRNA H19 as a diagnostic marker for coronary artery disease

SUMMARY OBJECTIVE: Our study aimed to investigate the diagnostic value of lncRNA H19 for coronary artery disease (CAD) and to explore its possible mechanisms. Methods: A total of 30 CAD patients and 30 healthy individuals, as well as patients with different cardiovascular diseases, were included in thi...

Salvianolic acid A alleviates the renal damage in rats with chronic renal failure

Acta cir. bras; 34 (2), 2019
Abstract Purpose: To investigate the protective effects of salvianolic acid A (SAA) on renal damage in rats with chronic renal failure (CRF). Methods: The five-sixth nephrectomy model of CRF was successfully established in group CRF (10 rats) and group CRF+SAA (10 rats). Ten rats were selected as sha...

The role of KDR in intrauterine adhesions may involve the TGF-β1/Smads signaling pathway

Braz. j. med. biol. res; 52 (10), 2019
The aim of this study was to investigate the role of kinase-insert domain-containing receptor (KDR) in intrauterine adhesions (IUA) and its mechanism. The Case group consisted of 92 patients diagnosed with IUA, and the Control group included 86 patients with uterine septum who had normal endometrium veri...

Beneficial effects of Oltipraz, nuclear factor - erythroid - 2 - related factor 2 (Nrf2), on renal damage in unilateral ureteral obstruction rat model

Int. braz. j. urol; 44 (6), 2018
ABSTRACT Introduction: We investigated whether Oltipraz (OPZ) attenuated renal fibrosis in a unilateral ureteral obstruction (UUO) rat model. Materials and Methods: We randomly divided 32 rats into four groups, each consisting of eight animals as follows: Rats in group 1 underwent a sham operation and ...

Expressions of transforming growth factor β1 signaling cytokines in aortic dissection

Abstract Objective: To demonstrate the underlying mechanisms of aortic dissection compared to those of coronary artery disease in terms of the transforming growth factor-beta (TGF-β) signaling pathway. Methods: Twenty consecutive aortic dissection patients and 20 consecutive coronary artery diseas...
