Aldehydes are relevant analytes in a wide range of samples, in particular, food and beverages but also body fluids. Hydrazines can undergo nucleophilic addition with aldehydes or ketones giving origin to hydrazones (a group of stable imines) that can be suitably used in the identification of aldehydes. Herein, 4-hydrazinobenzoic acid (HBA) was, for the first time, used as the derivatizing agent in analytical methodologies using liquid chromatography aiming the determination of low-molecular aldehydes. ...

This study investigated the anti-inflammatory activity of the extract (LEG) and purified (LPG) lycopene from guava (Psidium guajava L.), as well as some mechanisms possibly involved in this effect. The anti-inflammatory activity was initially assessed using paw edema induced by Carrageenan, Dextran, Compound 48/80, Histamine and Prostaglandin E2 in Swiss mice. A peritonitis model was used to evaluate neutrophil migration, the activity of myeloperoxidase (MPO) and reduced glutathione (GSH) concentration; ...

In the present work, an artificial neural network hybridized with a genetic algorithm (ANN-GA) has been applied to optimize Penicillium roqueforti ATCC 10110 lipase production in solid-state fermentation (SSF). For such a purpose, a feed-forward ANN with polynomial configuration 3-49-1 (i.e. 3 neurons in the input layer, 49 neurons in the hidden layer and 1 neuron in the output layer) was used to computationally model the experiment and a GA was used to optimize lipase production through the ANN model. ...

Insufficient housing quality is associated with stress and mental health impacts. Crowding, pollution, noise, inadequate lighting, lack of access to green spaces, and other environmental factors associated with slums can exacerbate mental health disorders, including depression, anxiety, violence, and other forms of social dysfunction. The studies were identified using large-sized newspapers with international circulation. Experts say that people who sleep in shelters or on the streets already have ...

Aracaju foi uma cidade planejada com simplicidade e rigor geométrico. Desde a sua fundação, ela vem passando por constantes alterações, havendo cada vez menos áreas verdes no ambiente urbano. A arborização urbana bem planejada é muito importante, pois as árvores trazem benefícios à cidade nos processos de ordens ecológica (clima e poluição), biológica (saúde física do homem) e psicológica (saúde mental do homem). Porém, a falta de planejamento dessa arborização e o uso inadequado de algumas espécies ...

In this document we describe the development of a remote lab and two user interfaces for teaching programming and fundamentals of robotics using Arduino boards. One of the interfaces uses visual language to make the experience more attractive for those who are beginning their studies. The second interface provides an environment similar to the original Arduino's one for those users who have some background to use textual programming language. In addition, we present an usability evaluation of the ...

Poecilia velifera is a popular fish in freshwater aquarism that naturally inhabits aquatic habitats with a wide range of salinities. Nonetheless, the effects of different salinities on the reproductive success and sex ratio of the species remain unknown. Male sex characters, sex ratio and reproductive success of P. velifera were evaluated by maintaining 160 juveniles (0.078 ± 0.011 g) in four different salinities (0; 12; 24; 36 g/L), with four replicates. The only modification observed in males was ...

Cross-laminated timber (CLT) has been widely discussed as a relevant industrialized construction solution. Numerous publications have considered CLT as a structural wood-based panel, but other documents have mentioned it as a building or even a construction system. Many authors address its application in multistory buildings, although single-family houses and lower building applications have become desirable topics as well. Given these gaps, this review study addresses a systematic method to evince ...

Human papillomavirus (HPV) and Trichomonas vaginalis (TV) infections are the most common sexually transmitted infections (STIs) globally. The latter has contributed to a variety of adverse outcomes for both sexes. Moreover, in Brazil, epidemiological studies on patients with STIs are limited. Therefore, this study aimed to determine the prevalence of TV and its association with HPV in women undergoing cervical cancer screening.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive disorder caused by pathogenic variants in CYP27A1, leading to a deficiency in sterol 27-hydroxylase. This defect results in the accumulation of cholestanol and bile alcohols in various tissues, including the brain, tendons and peripheral nerves. We conducted this review to evaluate lipid profile abnormalities in patients with CTX. A search was conducted in PubMed, Embase and the Virtual Health Library in January 2023 to evaluate studies ...

For personal protection against high kinetic energy projectiles, multilayered armor systems (MAS) are usually the best option. They combine synergistically the properties of different materials such as ceramics, composites and metals. In the present work, ballistic tests were performed to evaluate multilayered armor systems (MAS) using curaua non-woven fabric epoxy composites as second layer. A comparison to a MAS using aramid (Kevlar™) fabric laminates was made. The results showed that the curaua ...

In agricultural production, nitrogen (N) deficiency reduces yield, while overapplication may have an unwanted impact on the natural environment and farm finances. Frequent field N monitoring is impractical due to the time and cost required for traditional laboratory analysis. However, remotely sensed data are an alternative to evaluate and monitor crop nutrition status throughout the growing season. This study evaluates the spatial distribution of N in pasture fields cultivated under an integrated ...

Coffee (Coffea arabica L.) is an important global commodity grown in tropical areas where increased drought severity and frequency are believed to become progressively important due to climate changes. Nonetheless, elevated air [CO2] is thought to be able to mitigate heat and drought stresses. In this study, we tested how carbon assimilation and use are affected by elevated [CO2] in combination with a progressive drought, and how this could impact shifts on biomass accumulation and partitioning.

The excess level of carbon dioxide in the atmosphere has contributed a lot to global warming, occasioning several damages to the planet. Therefore, it is urgent to find ways to capture this gas. Then, the present work analyzed the temperature effect in CO2 absorption through deep eutectic solvents (DESs) based on urea and choline chloride using an in silico approach. The Molecular Dynamics (MD) simulations indicated that the increased temperature reduced the interaction potential of carbon dioxide ...

Precision Agriculture (PA) commonly uses interpolation to generate maps for site-specific management. Semivariogram modeling with kriging interpolation considerers several parameters such as trend and anisotropy, which require proper estimation to return reliable maps. Often present in agricultural fields, these directional effects can also account for machine traffic and crop/soil management. Despite modeling trend and anisotropy being desirable for creating soil fertility maps, these effects are ...
