Green Chiral HPLC Method for Lumefantrine Analysis: Method Development, Greenness Assessment, and Computational Studies

Chirality, Volume 38, Issue 8, August 2026.
A green chiral HPLC method was developed and validated for the determination of lumefantrine enantiomers. The method employs ethanol as a mobile phase as a sustainable and efficient alternative to hexane. The chiral recognition mechanism and elution order of the enantiomers were investigated using electronic circular dichroism and molecular docking ...

New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

Journal of Applied Toxicology, Volume 46, Issue 8, Page 2884-2894, August 2026.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Landscape configuration and soil properties shape ant‐mediated seed dispersal in tropical dry forest agricultural landscapes

Journal of Animal Ecology, Volume 95, Issue 8, Page 1476-1487, August 2026.
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Pesticide prioritization based on risk and model diet proposals for assessing cumulative exposure to pesticide residues in the Brazilian population through food consumption

Pest Management Science, Volume 82, Issue 4, Page 3853-3873, April 2026.
A risk classification of registered pesticides in Brazil was conducted, and the contribution of food to cumulative pesticide exposure was evaluated. Model diets were proposed, based on Brazilian consumption patterns. Abstract BACKGROUND Pesticide residue exposure assessments can be carried out during both the pre‐regulation and post‐regulation phases ...

The role of tropical forest fragment vegetation in maintaining arthropod diversity and spillover to adjacent sugarcane fields O papel da vegetação de fragmentos de floresta tropical na manutenção da diversidade de artrópodes e na sua disseminação para campos de cana‐de‐açúcar adjacentes

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 82-93, February 2026.
Tree diversity increases arthropod richness and the abundance of beneficial arthropod groups within Atlantic Forest fragments. Higher insect richness in forest fragments is associated with greater richness in adjacent sugarcane fields, and both habitats share insect families, suggesting spillover.
