1. MECANISMO DE EVOLUÇÃO DE HIDROGÊNIO DURANTE A CORROSÃO DA LIGA 2198-T8 EM MEIO CONTENDO CLORETO: UMA ABORDAGEM ELETROQUÍMICA
Corrosion is still one of the most serious and frequent problems in industries. The phenomena involved in the corrosion mechanism of Al-alloys may be explained by formation of galvanic cells between the metal matrix and heterogeneities, such as precipitates, intermetallic phases leading to potential differences and electrochemical reactions. In the cathodic

2. Separation of gadolinium and europium from chloride media by the solvent extraction technique
Abstract Obtaining rare earth elements (REE) is a complicated task, due mainly to the difficulty of separating and purifying them. Solvent extraction is the most widely used technique for separating REE, and the most common extractants used are organophosphorus acids. The low selectivity of this technique leads to the need for a high number of extraction cel

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. Synthesis, Molecular Modelling and Anticancer Activities of New Molecular Hybrids Containing 1,4-Naphthoquinone, 7-Chloroquinoline, 1,3,5-Triazine and Morpholine Cores as PI3K and AMPK Inhibitors in the Metastatic Melanoma Cells
Three molecular hybrids containing 1,4-naphthoquinones, 1,3,5-triazines, morpholine and 7-chloroquinoline, which have recognized contributions to the biological activity of many drugs, were synthesized in yields ranging from 43-84%. All hybrids were obtained in three steps starting from readily available reactants: lawsone, cyanuric chloride, morpholine and

5. Increased whitening efficacy and reduced cytotoxicity are achieved by the chemical activation of a highly concentrated hydrogen peroxide bleaching gel
Abstract Objective This study was designed for the chemical activation of a 35% hydrogen peroxide (H2O2) bleaching gel to increase its whitening effectiveness and reduce its toxicity. Methodology First, the bleaching gel - associated or not with ferrous sulfate (FS), manganese chloride (MC), peroxidase (PR), or catalase (CT) - was applied (3x 15 min) to

6. Effects of benzalkonium chloride and cyclosporine applied topically to rabbit conjunctiva: a histomorphometric study
RESUMO Objetivo: A instilação crônica de cloreto de benzalcônio, um conservante, tem efeitos inflamatórios na superfície ocular. No entanto, a adição do agente anti-inflamatório ciclosporina a um protocolo terapêutico pode atenuar esses efeitos. Este estudo comparou os efeitos tóxicos de uma solução de cloreto de benzalcônio a 0,1% e o possív

8. Evaluation of cytotoxicity and wound healing activity of Avicennia schaueriana in cream
Abstract:Avicennia schaueriana is found in Brazilian mangrove coast. The cytotoxicity in vitro of the Aqueous Extract of Leaves of Avicennia schaueriana (AELAs) and the healing activity of the plant in cream on mice skin wounds were evaluated in this study. The cytotoxic evaluation was performed on Vero cells. The healing activity was evaluated on mice treat

9. 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

10. Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats
Abstract Reports have indicated that serotonin plays an important role in cell migration and differentiation during the organogenesis of several tissues, including the oral types. Administration of selective serotonin reuptake inhibitor (SSRI) drugs during pregnancy could affect the delivery of serotonin to embryonic tissues altering its development. Object

11. Immunohistochemical Expression of TGF-β1 and Osteonectin in engineered and Ca(OH)2-repaired human pulp tissues
Abstract The aim of the present study was to evaluate the expression of transforming growth factor-β1 (TGF-β1) and osteonectin (ON) in pulp-like tissues developed by tissue engineering and to compare it with the expression of these proteins in pulps treated with Ca(OH)2 therapy. Tooth slices were obtained from non-carious human third molars under sterile p
