Avaliação clínica, morfológica e molecular do carcinoma epidermoide oral com envolvimento mandibular

O carcinoma epidermóide (CEC) é a neoplasia maligna mais frequente em cavidade oral, representando aproximadamente 90% de todos os cânceres da boca. Esta neoplasia tem origem no epitélio de revestimento bucal, e a depender do subtipo e da sua localização, pode apresentar tendência marcante de inva...

Association between genetic polymorphisms in rank, rankl and opg and peri-implant diseases in patients from the Amazon Region

Braz. dent. j; 31 (1), 2020
Abstract The present study evaluated polymorphisms in RANK, RANKL and OPG-encoding genes to assess whether they are associated with mucositis and peri-implantitis in a population from the Brazilian Amazon region. One hundred and fourteen patients with dental implants were included in the study. After cli...

Avaliação dos níveis séricos e salivares de RANKL, OPG, IL-1?, IL-6 e TNF-? e sua relação com o índice da cortical mandibular em pacientes com cirrose hepática

Pacientes com cirrose hepática podem desenvolver osteoporose como complicação relacionada ao déficit funcional hepático. O objetivo desse estudo é o de avaliar a presença de proteínas relacionadas ao metabolismo ósseo (RANKL, OPG, IL-1?, IL-6 e TNF-?) na saliva e no sangue de pacientes cirrótic...

Receptor Activator of Nuclear Factor-Kappa Ligand and Osteoprotegerin Expressions on Hyperglycemic Wistar Rats (Rattus Novergicus) During Orthodontic Tooth Movement

Abstract Objective: To investigate the differences of receptor activator of nuclear factor-κB ligand (RANKL) and Osteoprotegerin (OPG) expressions between normoglycemic and hyperglycemic Wistar rats (Rattus Novergicus) during Orthodontic Tooth Movement (OTM). Material and Methods: This study was t...

Impact of history of periodontitis on gene expression of bone-related factors in young patients

Abstract Although dental implants and bone regenerative procedures are important approaches for the reestablishment of esthetics and function in young patients with a history of generalized aggressive periodontitis (GAP), no predictable outcomes have been reported, and the host osteo-immunoinflammatory r...

Effect of enhanced masticatory force on OPG, RANKL and MGF in alveolar bone of ovariectomized rats

J. appl. oral sci; 28 (), 2020
Abstract Menopause induces oral bone loss, leading to various oral diseases. Mastication importantly affects bone metabolism in the jawbone. Objective: To analyze the effect of enhanced masticatory force on osteoprotegerin (OPG), receptor activator of nuclear factor kappa B ligand (RANKL), and mechano-g...

Intercellular mediators in bone remodeling regulation in the experimental renal pathology

Actual. osteol; 15 (3), 2019
Bone metabolism disorders are characterized by an imbalance of bone resorption and formation in the bone remodeling process. Glucocorticoids that are used to treat kidney diseases exacerbate these disorders. P-selectin and galectin-3 are molecules involved in the sclerotic process in kidney, whereas bone...

Clinical attachment loss and molecular profile of inflamed sites before treatment

J. appl. oral sci; 27 (), 2019
Abstract Objective: To monitor early periodontal disease progression and to investigate clinical and molecular profile of inflamed sites by means of crevicular fluid and gingival biopsy analysis. Methodology: Eighty-one samples of twenty-seven periodontitis subjects and periodontally healthy individual...

Effect of risperidone on proliferation and apoptosis of MC3T3-E1 cells

Braz. j. med. biol. res; 52 (3), 2019
This aim of this study was to assess the molecular mechanism of osteoporosis in schizophrenia patients with risperidone use. Here, we investigated the effects of risperidone on cellular proliferation and apoptosis of a preosteoblast cell line, MC3T3-E1. Cell viability and apoptotic rate of MC3T3-E1 were ...

Beneficial effects of Cuscuta chinensis extract on glucocorticoid-induced osteoporosis through modulation of RANKL/OPG signals

Braz. j. med. biol. res; 52 (12), 2019
Cuscuta chinensis Lam. (Convolvulaceae) is an important herbal medicine widely used to improve sexual function, treat osteoporosis, and prevent aging, and has been reported to exhibit anti-osteoporotic effects in vitro. However, the activity of Cuscuta chinensis Lam. on glucocorticoid-induced osteoporosi...
