The success of pollen-pistil interaction in Mauritia flexuosa (buriti), a palm adapted to the humid ecosystems, 'veredas', within the Cerrado, is influenced by intrinsic and environmental factors. Its supra-annual flowering, dioecy, and adverse climate conditions pose challenges for fertilization, therefore information on floral biology is essential. This study aimed to ascertain stigma receptivity, and elucidate structural, cytochemical, and ultrastructural aspects of the pollen-pistil relationship.

Retinal ischemia-reperfusion (IR) injury is a major cause of vision loss worldwide, with ferroptosis, oxidative stress, and inflammation playing key roles in its pathogenesis. Currently, treatments targeting multiple aspects of this condition are limited. This study introduces a supramolecular nanoparticle combining the phosphodiesterase 4 (PDE4) inhibitor crisaborole and the ferroptosis inhibitor deferoxamine to address these pathological processes.
