1. Influence of sonication and in vitro evaluation of nifedipine self-nanoemulsifying drug delivery system
In order to develop a self-nanoemulsifying system, three components, olive oil, Tween 80, and Capmul, were used to construct a ternary phase diagram that helped to find the optimum formulation, which was loaded with nifedipine. The effect of sonication on drug loading was also evaluated. After that, measurement of the droplet size, size distribution, zeta po

5. Influence of the composition and shades of ceramics on light transmission and degree of conversion of dual-cured resin cements
Abstract Objective Since the transmittance of ceramics can influence the degree of conversion (DC) of resin cements, ceramics composition and shade should be considered in the selection of resin cement. This in vitro study aimed to evaluate the effect of the transmittance of different composition, opacities and shades of ceramics on the degree of conversio

6. Micropropagation and Cellular Behaviour Changes During in vitro Flowering of Impatiens balsamina
RESUMO: Neste estudo, a micropropagação de Impatiens balsamina foi estabelecida a partir de explantes de caule e parte aérea. Os efeitos do GA3 e da glutationa na morfogênese dessa espécie também foram investigados, de modo a induzir o florescimento in vitro. Verificou-se que a melhor regeneração in vitro de plantas foi obtida em meio MS adicionado c

10. Efficiency of polymerization of bulk-fill composite resins: a systematic review
Abstract This systematic review assessed the literature to evaluate the efficiency of polymerization of bulk-fill composite resins at 4 mm restoration depth. PubMed, Cochrane, Scopus and Web of Science databases were searched with no restrictions on year, publication status, or article’s language. Selection criteria included studies that evaluated bulk-fil

11. Preparation of Two Maleic Acid Sulfonamide Salts and Their Copper(II) Complexes and Antiglaucoma Activity Studies
Two novel proton transfer compounds (HAP)+(SAMAL)- and (HBI)+(SAMAL)-.H2O were obtained from (E)-4-oxo-4-(4-sulfamoylphenylamino)but-2-enoic acid (HSAMAL) and 2-aminopyridine (AP) or 1H-benzimidazole (BI), respectively. Copper(II) complexes of salts and of HSAMAL have also been prepared. They have been characterized by elemental, spectral, thermal analyses,

12. TiF4 and NaF varnishes as anti-erosive agents on enamel and dentin erosion progression in vitro
Objective This study assessed the effect of fluoride varnishes on the progression of tooth erosion in vitro. Material and Methods: Forty-eight enamel and 60 root dentin samples were previously demineralized (0.1% citric acid, pH 2.5, 30 min), leading to a baseline and erosive wear of 12.9 and 11.4 µm, respectively. The samples were randomly treated (6 h) w
