Quercetin protective potential against nanoparticle-induced adverse effects.

The rapid development of nanotechnology has resulted in the widespread use of nanoparticles (NPs) in various sectors due to their unique properties and diverse applications. However, the increased exposure of humans to NPs raises concerns about their potential negative impact on human health and the environment. The pathways through which NPs exert adverse effects, including inflammation and oxidative stress, are primarily influenced by their size, shape, surface charge, and chemistry, underscoring the critical need to comprehend and alleviate their potential detrimental impacts.

Inulin or xylooligosaccharide addition to dulce de leche affects consumers' sensory experience and emotional response.

The growing interest in reducing sugar and fat in processed foods has led to the use of fibers with prebiotic potential, such as inulin and xylooligosaccharide (XOS), as substitutes capable of enhancing nutritional value and sensory quality. Using an innovative approach with Free Just-About-Right (FREE JAR) to obtain Drivers of Liking, this study evaluated consumer perception (n = 129) regarding the impact of adding inulin and XOS to Dulce de Leche with or without fat reduction. The term "Too Greasy" was significant for the product made with whole milk; however, adding inulin and XOS mitigated this effect and promoted the sensation of JAR sweetness.

Presence of multidrug-resistant bacteria on ready-to-use laryngoscope blades and handles: a cross-sectional study.

Background: The presence of microorganisms in laryngoscopes emphasizes the risk to patient safety during orotracheal intubations.

Methods: Cross-sectional study was carried out in university hospital in the inpatient, emergency, intensive care and surgical center sectors. Microorganisms were recovered from the blades using a filter membrane and from the handles using swab.

Overcoming resistance to arginine deprivation therapy using GC7 in pleural mesothelioma.

Pleural mesothelioma is a highly chemotherapy-resistant cancer. Approximately 50% of mesotheliomas do not express argininosuccinate synthetase 1 (ASS1), the rate-limiting enzyme in arginine biosynthesis, making arginine depletion with pegylated arginine deiminase (ADI-PEG20) an attractive therapeutic strategy. We investigated whether combinatory treatment composed of ADI-PEG20 and polyamine inhibitors constitutes a promising novel therapeutic strategy to overcome ADI-PEG20 resistance in mesothelioma patients.

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.
