Variation in apparent wood density of Tachigali vulgaris as affected by tree diameter, height, forking, and soil conditions in Amazonian plantations

Abstract Tachigali vulgaris has potential for energy purposes in the Amazon, but the relationship between several silvicultural factors and wood quality requires further investigation. This study evaluated the variation in the apparent density of T. vulgaris wood in two pure plan...

Persistent Redox Imbalance in Post-COVID-19 Syndrome: Lipid Peroxidation, Antioxidant Enzyme Depletion, and Reduced Nitric Oxide Availability in an Amazonian Population

Post-COVID-19 syndrome (PCS) can persist even after mild acute illness, and oxidative stress has been proposed as a central mechanism for this persistence, although it remains poorly studied in the Amazon. This study characterized redox imbalance in patients with PCS through a co...
