Effects of different remineralizing agents on color stability and surface characteristics of the teeth following vital bleaching

The aim of the study was to investigate the effects of various remineralizing agents on the color stability and surface characteristics of the teeth after vital bleaching. The extracted 96 human incisors were used for the study. Initially, the samples were randomly divided into two groups and exposed to in-office and at-home bleaching agents. Then, the groups were divided into six subgroups (n = 8), including the control group did not undergo remineralization after bleaching, according to five remineralizing agents (Gelato APF Gel, Remin Pro, Tooth Mousse, MI Paste Plus, Curodont Protect). Surface roughness was assessed at baseline, after bleaching and remineralization procedures. Color measurements of the samples were obtained at baseline, after bleaching and then after immersion in the staining solution following remineralization process. Scanning electron microscopy and atomic force microscopy (AFM) analyzes were carried out in order to examine the morphological changes on the surface of the enamel. The independent t-test, paired-samples t-test, and one-way ANOVA was used to compare the data and post-hoc LSD test to compare the difference among the study groups (alpha = .05). Surface roughness increased following in-office and at-home bleaching in all groups, and reduced after application of remineralizing agents in all groups. Significant differences were found among the groups with respect to changes in surface roughness and color values following treatment with remineralizing agents (p <.05). AFM analyses revealed increased surface roughness after bleaching and a reduction of rough surfaces following treatment with remineralizing agents. Remineralizing agents can be used to reduce postbleaching increase in surface roughness and to maintain color stability after bleaching

SUCCESS OF ENSEMBLE ALGORITHMS IN CLASSIFICATION OF ELECTRICAL IMPADENCE SPECTROSCOPY BREAST TISSUE RECORDS

In this study was performed by using records from breast tissue electrical impedance spectroscopy analysis. The aim of the study is to reveal the impact of ensemble algorithms on success of the classification performance in the classification of normal and pathological breast tissue classification. For this purpose have been used three different ensemble algorithms they are bagging, adaboost, random subspaces and three main basic classifiers, which are RF, YSA, DVM. The results obtained are supplemented with performance analysis and ensemble algorithms have been demonstrated to increase classification performance results. The results obtained by the combined use of adaboost ensemble algorithm with RF basic classifier demonstrate, that the success rate was higher than the others (%89.62)

Intermolecular heterocyclization of alkynones with 2-mercaptoacetaldehyde under metal-free conditions: synthesis of 2,3-disubstituted thiophenes

WOS: 000362533900004A concise and regioselective approach for the synthesis of 2,3-disubstituted thiophene derivatives has been developed. The synthetic strategy relies on the reaction of an in situ generated 2-mercaptoacetaldehyde with various alkynones. Furthermore, we calculated the energy gap between the HOMO and the LUMO orbitals of all compounds and observed that the introduction of a strong electron-withdrawing group decreased the HOMO-LUMO energy gap.

Do ANCA-associated vasculitides and IgG4-related disease really overlap or not?

Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and immunoglobulin G4-related disease (IgG4-RD) have some common features. The co-occurrence/concurrence of AAV and IgG4-RD was recently published by the collaborative European Vasculitis Study Group. First, we aimed to investigate ANCA positivity of our IgG4-RD cohort. Second, a literature review of co-occurrence/concurrence of AAV and IgG4-RD was done. Methods: Data of 62 patients with IgG4-RD in Hacettepe Vasculitis Center Database were used. Patient dataset was designed to include demographic data, clinical characteristics, imaging and IgG4-RD, AAV and ANCA test results. At the next step, we performed a systematic literature review in PUBMED database covering the time period from 1976 until April 2018. Relevant publications were searched using these MeSH terms ''IgG4-related disease and Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis'', "IgG4-related disease and Eosinophilic Granulomatosis with Polyangiitis", "IgG4-related disease and Microscopic Polyangiitis" and "IgG4-related disease and Granulomatosis with Polyangiitis". Results: Three (10.3%) of 29 patients had low titer ANCA positivity. These three patients didn't have any findings of vasculitis and no granuloma was seen in biopsy. In the literature review, we found 17 cases had features of both IgG4-RD and AAV. These cases were re-evaluated according to the Comprehensive Diagnostic Criteria for IgG4-RD. ANCA were positive in 15 of 17 patients (88%). Conclusion: None of our IgG4-RD patients overlapped with AAV. Only two patients in the literature review seemed to be fully compatible with both diseases. Even though AAV and IgG4-RD share similar clinical features, we think this might be a co-occurrence instead of a histopathological link.PubMe

Improvement of Hot Air Dried Bitter Gourd (<i>Momordica charantia</i> L.) Product Quality: Optimization of Drying and Blanching Process by Experimental Design

Bitter gourd (Momordica charantia L.) is a plant species belonging to the Cucurbitaceae family, growing in tropical regions and containing health-promoting beneficial compounds. In the current study, bitter gourds prepared for drying were sliced in three different thicknesses (6, 8 and 10 mm) and dried in a hot-air dryer at three different temperatures (60, 70 and 80 °C) to preserve their medicinal efficacy. In the experiments, the samples were subjected to blanching at 93.5 °C and 2% salt water for 0, 2.5 and 5 min, and drying processes were conducted. After the drying process, drying time, total color change (∆E), total phenolic content (TPC), total antioxidant activity (TAA), and vitamin C properties were examined. The highest levels of TPC and TAA were found at lower drying air temperatures (DATs), and while these values increased with longer blanching times at lower DATs, they decreased with longer blanching times at higher DATs. According to the different drying temperatures used, it was discovered that the total color change peaked at 70 °C and that vitamin C levels declined as DAT rose. The optimal drying conditions for the 3D response surface methodology include 60 °C DAT, a slice thickness of 10 mm, and without blanching to maximize TPC, TAA and vitamin C content and minimize drying time and ∆E
