Efeito de sistemas de embalagens na estabilidade da farinha de raspa de mandioca biofortificada.

Produtos de mandioca biofortificados com alto teor de carotenóides são fontes de vitamina A, mas devem ser acondicionado em sistemas de embalagem que retardem a degradação dos carotenóides para prolongar a vida de prateleira

Influência do acondicionamento na retenção de B-caroteno em farinha de raspa de mandioca biofortificada.

Neste estudo avaliou-se o uso de uma embalagem de PETmet/PEBD na retenção de carotenóides da farinha de raspa de mandioca sendo realizado o acondicionamento do produto com e sem vácuo com posterior estocagem a 25 °C/75% UR. Observa-se aos 45 dias de estocagem uma perda superior a 50% de ß-caroteno na embalagem PETmet/PEBD sem vácuo, e 30% no PETmet/PEBD com vácuo aos 118 dias de estocagem

Electrochemical chemically based sensors and emerging enzymatic biosensors for antidepressant drug detection: a review

Major depressive disorder is a widespread condition with antidepressants as the main pharmacological treatment. However, some patients experience concerning adverse reactions or have an inadequate response to treatment. Analytical chromatographic techniques, among other techniques, are valuable tools for investigating medication complications, including those associated with antidepressants. Nevertheless, there is a growing need to address the limitations associated with these techniques. In recent years, electrochemical (bio)sensors have garnered significant attention due to their lower cost, portability, and precision. Electrochemical (bio)sensors can be used for various applications related to depression, such as monitoring the levels of antidepressants in biological and in environmental samples. They can provide accurate and rapid results, which could facilitate personalized treatment and improve patient outcomes. This state-of-the-art literature review aims to explore the latest advancements in the electrochemical detection of antidepressants. The review focuses on two types of electrochemical sensors: Chemically modified sensors and enzyme-based biosensors. The referred papers are carefully categorized according to their respective sensor type. The review examines the differences between the two sensing methods, highlights their unique features and limitations, and provides an in-depth analysis of each sensor.info:eu-repo/semantics/publishedVersio

Motion of influential players can support cooperation in Prisoner's Dilemma

We study a spatial Prisoner's dilemma game with two types (A and B) of players located on a square lattice. Players following either cooperator or defector strategies play Prisoner's Dilemma games with their 24 nearest neighbors. The players are allowed to adopt one of their neighbor's strategy with a probability dependent on the payoff difference and type of the given neighbor. Players A and B have different efficiency in the transfer of their own strategy therefore the strategy adoption probability is reduced by a multiplicative factor (w < 1) from the players of type B. We report that the motion of the influential payers (type A) can improve remarkably the maintenance of cooperation even for their low densities.Comment: 7 pages, 7 figure
