Este estudo investigou a produção de nanopartículas de hidroxiapatita a partir de escamas de peixe calcinadas em diferentes temperaturas (400, 600, 800 e 1000 °C), com o objetivo de avaliar o efeito da temperatura de calcinação na cristalinidade e sua influência na liberação de...

Abstract Background: Obesity in cats is a complex metabolic condition, and understanding its metabolic processes is e ssential for gaining new insights into nutrition. Hypothesis/Objectives: Investigate the effects of enzymatically-hydrolyzed poultry byproduct meal (EHPM-c) on the serum metabolomic p&...

The continuous increase in global energy consumption is primarily driven by the rapid expansion of urban areas and acccelerated industrialization. This has led to a need for the integration of renewable energy systems, aimed at enhancing sustainability, alongside the demand for more eff...

In semiarid regions, soil organic carbon (SOC) stocks and soil organic matter (SOM) pools are often low due to limited biomass input and inadequate management. This study evaluated SOC stocks and SOM fractions in a forage cactus–sorghum intercropping system irrigated with treated sewage...

The widespread use of antibiotics has raised concerns about their residues in dairy products, meat, fish, and poultry, which can pose risks to human health and lead to substantial economic losses. Therefore, the rapid, sensitive, and cost-effective detection of low concentrations of var...

Gullies are erosive features developed through water erosion processes, which combine runoff and subsurface water flow, which can mobilize great volumes of soil and cause severe impacts to both rural and urban areas. The south of Minas Gerais (Brazil) has been affected by soil ...

The uncontrolled discharge of synthetic dyes into aquatic environments poses severe environmental and public health risks due to their high stability, persistence, and toxicity. Moreover, most existing treatment technologies are inefficient, costly, or unsustainable for recalcitrant dyes, particularly azo&...

Copaiba oil-resin (CO), extracted from trunks of various copaiba species, has several therapeutic and cosmetic properties and is a valuable non-timber forest product that contributes to preservation of the Amazon rainforest. Unfortunately, adulteration of this oil-resin with cheaper vegetable oils...

Chitinases catalyze the hydrolysis of β-1,4-glycosidic bonds in chitin, a structural biopoly mer synthesized by numerous organisms. Although these enzymes have been widely investigated, studies focusing on insect-derived chitinases remain limited. In this study, three recombinant chitinases from the l...
