Electrochemical Magnetic Immunoassay for the Determination of the Fish Allergen β-Parvalbumin.

β-parvalbumin (β-PV) is the primary fish allergen responsible for most allergic reactions in individuals sensitive to fish. To ensure food safety, a sandwich-based magnetic immunoassay was developed using maleimide-functionalized magnetic beads (NH-MBs). Specific anti-β-PV antibodies were immobilized on these MBs, and a screen-printed carbon electrode was employed as the electrochemical transducer.

Metal concentrations, oxidative status and histopathological evaluation of fish species from Doce River, Brazil, after the Fundao dam collapse.

Eight years after the tailings dam collapse in Mariana, MG, Brazil, several aspects of this massive disaster are yet to be elucidated. Our goal was to investigate the impact of the mud flow on 16 fish species collected across 15 points from the Doce River, addressing 12 metal concentrations, tissue oxidative status (antioxidant enzymes and stress biomarkers), and histopathological analyses. The species Trachelyopterus striatulus, Prochilodus vimboides, Loricariichthys castaneus, Lophiosilurus alexandri, Hypostomus affinis, Hoplias intermedius were shown to be the most affected regarding the gills tissue integrity; Hypostomus affinis, Oligosarcus acutirostris, Lophiosilurus alexandri, Pygocentrus nattereri, Hoplosternum littorale, and Loricariichthys castaneus showed the highest levels of liver health.

Characterization and analysis of the bioactivity of the Piper rivinoides Kunth essential oil and its components myristicin and elemicin, against opportunistic fungal pathogens.

Candidiasis is an infectious disease caused by some fungi of the genus Candida. In Brazil, the incidence rate is higher than in European countries and the United States, and health problems occur mainly due to the virulence factors of the fungi, which have made treatment with commercial drugs difficult. Considering the context, plants rich in phenolic compounds, such as those of the genus Piper, have been studied due to their antimicrobial properties.

Numerical data for modelling pavement deflection behaviour under the TSD.

This dataset provides a numerical simulation of pavement mechanical behavior under Traffic Speed Deflectometer (TSD) measurements. It consists of simulated deflection slope data for various pavement structures and subgrade properties, generated using the Alizé-LCPC software, a standard tool in French pavement engineering. The dataset addresses limitations in traditional Falling Weight Deflectometer (FWD) methods, offering a more accurate and computationally efficient approach for estimating the Subgrade Resilient Modulus (M) using machine learning models.

Effects of the passive self-ligating system on alveolar bone thickness, dental inclinations, and arch dimensions.

Background: We aimed to evaluate changes in buccal bone thickness (BBT), buccolingual dental inclinations (BLI), and transversal widths (TW) after treatment using a passive self-ligating system.

Material And Methods: Pre- and posttreatment cone-beam computed tomography images (CBCT) of 21 Class I patients (initial mean age: 14.99 ± 1.
