Carbon-dot pequi-nut in the development of immunosensor to detect pathogenic bacteria.

Carbon dots in biosensing have advanced significantly, adding improvements to different detection techniques. In this study, an amperometric immunosensor for Salmonella Thyphimurium was designed using antibodies labeled with carbon dots (Cdots) from pequi almond (Caryocar brasiliensis). Cdots were synthesized by pyrolysis and characterized by FTIR, UV/fluorescence, electrochemistry, zeta potential, and transmission electron microscopy (TEM).

Sodium hyaluronate microcapsules to promote antitumor selectivity of anacardic acid.

Anacardic acid (AA) is a phenolic lipid extracted from cashew nutshell liquid that has antitumor activity. Given the high hydrophobicity of this compound and aiming to create efficient vehicle for its administration in aqueous systems, the objective of the present work was to develop a microcapsule (MCAA) by spray dryer technique, based on the polysaccharide sodium hyaluronate (SH), containing AA as its core, encapsulated from nanoemulsion. The Encapsulation Efficiency of MCAA presented a value equal to 95.

Cascade reservoirs affect mercury concentrations in fish from Teles Pires river, Brazilian Amazon.

Hydroelectric reservoirs favor mercury contamination in biota, but the contamination in cascade reservoirs is not yet clear. We investigated total mercury (THg) contamination in fish in four cascade reservoirs in the Brazilian Amazon between August 2022 and April 2023. Overall, downstream predatory fish showed higher mercury concentrations than those upstream.

Engaging in cyber hygiene: the role of thoughtful decision-making and informational interventions.

Introduction: The effectiveness of human-centric cybersecurity largely depends on end-users' adherence to security and privacy behaviors. Understanding and predicting variations in the adoption of these safeguards is crucial for both theoretical advancement and practical application. While existing frameworks are often adapted from health science literature, there is potential to enhance these models by incorporating criminological constructs relevant to online victimization.

Relationship between Quality of Life and Swallowing in Hypertensive Individuals with Obstructive Sleep Apnea.

Introduction: Obstructive sleep apnea (OSA) is closely associated with resistant hypertension (RHTN). Individuals with OSA may have sensory and muscular alterations in pharyngolaryngeal structures, potentially resulting in oropharyngeal dysphagia.

Objective: One objective of this study was to assess and compare the quality of life (QoL) and swallowing ability of resistant hypertensive patients with and without OSA.
