1. O peróxido de hidrogênio (água oxigenada) tem efeito viricida eficaz, como bochecho pré-operatório (antes da realização de procedimentos odontológicos), no contexto da pandemia de COVID19?
Não, pois não há suporte na literatura científica para indicação de colutórios (bochechos) à base de peróxido de hidrogênio (água oxigenada) para controle da infecção viral como um todo, e do SARS COV2, em particular, associado com a falta de substantividade desses produtos, portanto, sua indicação em odontologia e protocolos de atendimento

2. Tailoring the properties of Y2O3 via synthesis parameters varied during the PVA-assisted sol-gel route
Abstract The effect of synthesis parameters on the microstructural behavior and morphology during the yttrium oxide (Y2O3) formation is reported. Y2O3 crystals were produced by a modified sol-gel route assisted by polyvinyl alcohol solution varying the calcination temperature and solution pH. The crystalline phase formation was investigated using X-ray powde

3. Honey of Tetragonisca angustula from Southwestern Bahia: Influence of Seasonality on the Physicochemical Profile and Glioma Cell Inhibitory Effect
This study aims to analyze Tetragonisca angustula honey from southwestern Bahia for its physicochemical characteristics, phenolic compounds and glioma cell inhibitory effect, in samples from different periods of the year, dry (DP) and rainy (RP) period. The analyses showed that samples obtained in the DP and RP are statistically different for the physicochem

4. Collector mixtures and their synergistic effect on quartz floatability
Abstract Sinergy is the interaction of two or more agents to produce a combined effect greater than the sum of their separate effects. Etherdiamine yields superior results for quartz floatability in a Hallimond tube and higher selectivity in the reverse bench scale cationic flotation of an iron ore, when compared to ethermonoamine. Blending these collectors

6. A New Approach for Histamine Functionalized Nanoparticles as Sorbent Phase for Bar Adsorptive Microextraction (BAµE) and Determination of Parabens in Water by HPLC-DAD
In this study, for the first time, histamine-functionalized magnetic nanoparticles (HIS-MNP) were used as sorbent phase combined with bar adsorptive microextraction (BAµE) for the determination of methylparaben (MP), ethylparaben (EP), propylparaben (PP), and butylparaben (BP) in water samples by high performance liquid chromatography coupled with diode arr

7. Effect of early awake prone positioning application on prognosis in patients with acute respiratory failure due to COVID-19 pneumonia: a retrospective observational study
Abstract Background: We evaluated the effect of early awake prone position administration on oxygenation and intubation requirements and short-term mortality in patients with acute respiratory failure due to coronavirus disease 2019 (COVID-19) pneumonia. Methods: This is an observational-cohort study. Patients receiving mask oxygen therapy in our intensive

8. Heterogeneous Fenton-like catalytic degradation of phenazine dye over CeO2 (CP-2) nanoscale powder
Abstract A heterogeneous Fenton-like process was explored for oxidation of phenazine dye using ceria polishing material (CP-2). XRD, SEM, FTIR, UV-vis DRS, and pHPZC techniques were applied to characterize the catalyst features. The performance of the heterogeneous Fenton-like process was investigated under various parameters (reaction time, pH, H2O2 concent

9. The use of white striped chicken breasts on the quality of nuggets and hamburgers
Abstract The objective of this study was to evaluate physically and chemically chicken breasts with different degrees of white striping (WS), as well as its effect on the process and quality of nuggets and hamburgers. Chicken breasts fillets were obtained from male chicken broilers weighing approximately 3 kg at the slaughterhouse and classified based on the

10. Effect of pH level and calcination on the production of calcium phosphates by acidic route of wet precipitation
Abstract Multiphasic calcium phosphate powders were synthesized by the acidic route, using lactic acid as a chelating agent that allows the production of a stable and rich solution of calcium and phosphate ions at room temperature. After pH adjusting, without varying the concentrations of precursor solution, XRD and FTIR analyses showed different CaP phases

11. Cashew nut-based beverage: development, characteristics and stability during refrigerated storage
Abstract A cashew nut-based beverage was obtained using broken cashew kernels and its composition and stability were evaluated during refrigerated storage for 60 days. Sensory tests were performed to define the formulation, testing the best proportion between kernels and water, the effect of kernel roasting, the ideal sweetness, the beverage attributes and t

12. Wine composition of Merlot and Cabernet Sauvignon vine clones under the environmental conditions of Serra Gaúcha, Brazil
Abstract This study aimed to evaluate the wine composition from vine clones of Merlot (181, 346, 347, 348) and Cabernet Sauvignon (R5, 18A, 163, 338, 341). The grapes were harvested between 2010 and 2012, then on the same day, taken to the winery facility for winemaking. After crushing and destemming the grapes, the musts were transferred to glass containers
