Construction Trade Work Is Associated With Accelerated Decline in Kidney Function
ABSTRACT Background Construction workers are exposed to airborne particulates, organic solvents, and metals—agents linked to elevated risk of chronic kidney disease (CKD). Few studies have evaluated whether construction trade work is associated with longitudinal changes in estimated glomerular filtration rate (eGFR), a key indicator of kidney function.

Abstract Macaúba (Acrocomia aculeata), a native species from Brazilian biomes, has emerged as a sustainable alternative to vegetable oil production. Its fruit presents high oil yield (3–6 ton/ha), extracted from its kernel and pulp. While the kernel is suitable for food and cosmetics application, the pulp oil has been considered as a promising ...
