Quality control of propolis plays a pivotal role in ensuring the appropriate concentrations of active compounds, limiting unwanted substances, verifying authenticity, and adhering to regulatory standards. This study aimed to assess the identity and quality standards, the individual phenolic composition (LC-ESI-MS/MS), and the antioxidant and antiglycemic potential of commercial propolis extracts (CPEs) from , , and bees. CPEs met wax content and oxidation activity criteria, surpassing minimum thresholds for total phenolic content (TPC) and flavonoid content (TFC), although stingless bee CPE did not test positive for 10% lead acetate.

Dietary supplementation of mineral nanoparticles for channel catfish (Ictalurus punctatus).

Fish Physiol Biochem

December 2024

Thad Cochran National Warmwater Aquaculture Center, Stoneville, MS Agriculture and Forestry Experiment Station, Mississippi State University, Stoneville, MS, 38776, USA.

This study evaluated the supplementation of iron and copper nanoparticles in channel catfish diets and their influences on growth and health. A comparative feeding trial was carried out for 9 weeks to evaluate combinations of iron and copper nanoparticles: only iron nanoparticles (IronNP), only copper nanoparticles (CopperNP), CopperNP + IronNP, and a control diet supplemented with inorganic iron and copper (FeSO and CuSO). After a 9-week feeding trial, growth performance, hematological parameters, whole-body proximate composition, and intestinal microbiota were evaluated, and fish were subjected to a bacterial challenge against Edwardsiella ictaluri to evaluate the contribution of the experimental treatments to fish health status.

Sugarcane straw removal for bioenergy production will increase substantially in the next years, but this may deplete soil organic carbon (SOC) and exacerbate greenhouse gas (GHG) emissions. These aspects are not consistently approached in bioenergy life cycle assessment (LCA). Using SOC modeling and LCA approach, this study addressed the life cycle GHG balance from sugarcane agroindustry in different scenarios of straw removal, considering the potential SOC changes associated with straw management in sugarcane-cultivated soils in Brazil.
