3. Impact of calcium aluminate cement with additives on dental pulp-derived cells
Abstract Calcium aluminate cement (CAC) has been highlighted as a promising alternative for endodontic use aiming at periapical tissue repair. However, its effects on dental pulp cells have been poorly explored. Objective: This study assessed the impact of calcium chloride (CaCl2) and bismuth oxide (Bi2O3) or zinc oxide (ZnO) additives on odontoblast cell re

4. Influence of photobiomodulation therapy on root development of rat molars with open apex and pulp necrosis
Abstract This study aimed to evaluate the role of photobiomodulation (PBM) in apexification and apexogenesis of necrotic rat molars with an open apex. Rat molars were exposed to the oral environment for 3 weeks. Canals were rinsed with 2.5% NaOCl and 17% EDTA, filled with antibiotic paste and sealed. After 7 days, canals were rinsed and divided into six grou

5. A SERM increasing the expression of the osteoblastogenesis and mineralization-related proteins and improving quality of bone tissue in an experimental model of osteoporosis
Abstract Raloxifene is an antiresorptive drug, selective estrogen receptor modulator (SERM) used in the treatment of osteoporosis. Objective To evaluate proteins related to bone repair at the peri-implant bone in a rat model of osteoporosis treated with raloxifene. Material and Methods 72 rats were divided into three groups: SHAM (healthy animals), OVX (ov

6. Cultivo orgânico de cebola sob adubação com torta de mamona e lâminas de irrigação
RESUMO. Foram realizados dois experimentos com objetivo de avaliar o efeito de diferentes doses de torta de mamona (0, 200 e 300 g m-2) e lâminas de irrigação (204, 224, 278 e 321 mm, em 2014 e 278, 302, 397 e 444 mm, em 2015) na produtividade e qualidade de bulbos de cebola, nos anos de 2014 e 2015. Nos experimentos o delineamento experimental foi em blo

7. Physical properties and biological effects of mineral trioxide aggregate mixed with methylcellulose and calcium chloride
Abstract Objectives: Methylcellulose (MC) is a chemical compound derived from cellulose. MTA mixed with MC reduces setting time and increases plasticity. This study assessed the influence of MC as an anti-washout ingredient and CaCl2 as a setting time accelerator on the physical and biological properties of MTA. Material and Methods: Test materials were di

9. Human plasma fibronectin promotes proliferation and differentiation of odontoblast
Abstract Objective To assess the effect of fibronectin (Fn) and porcine type I collagen (PCOL) on odontoblast-like cells in vitro. Material and Methods Rat odontoblast-like cells (MDPC-23 cells) were inoculated and cultured on Fn-coated or type I collagen-coated substrates. Proliferation assay, alkaline phosphatase activity (ALP activity), mRNA expressio

10. DNA methylation modulates H19 and IGF2 expression in porcine female eye
Abstract The sexually dimorphic expression of H19/IGF2 is evolutionarily conserved. To investigate whether the expression of H19/IGF2 in the female porcine eye is sex-dependent, gene expression and methylation status were evaluated using quantitative real-time PCR (qPCR) and bisulfite sequencing PCR (BSP). We hypothesized that H19/IGF2 might exhibit a differ

11. Short term sodium alendronate administration improves the peri-implant bone quality in osteoporotic animals
Abstract Sodium alendronate is a bisphosphonate drug that exerts antiresorptive action and is used to treat osteoporosis. Objective The aim of this study was to evaluate the bone repair process at the bone/implant interface of osteoporotic rats treated with sodium alendronate through the analysis of microtomography, real time polymerase chain reactions and

12. Estudo comparativo da diferenciação osteogênica das células tronco mesenquimais da medula óssea e do tecido adiposo de cães adultos
Resumo: O objetivo deste estudo foi comparar o potencial osteogênico das células tronco mesenquimais extraídas da medula óssea (CTM-MO) com as do tecido adiposo (CTM-AD) de cães adultos. As células foram caracterizadas fenotipicamente quanto à expressão de CD29, CD90, CD34 e CD45 e submetidas à diferenciação adipogênica e condrogênica por 21 dia
