Evaluating UCE Data Adequacy and Integrating Uncertainty in a Comprehensive Phylogeny of Ants.

While some relationships in phylogenomic studies have remained stable since the Sanger sequencing era, many challenging nodes remain, even with genome-scale data. Incongruence or lack of resolution in the phylogenomic era is frequently attributed to inadequate data modeling and analytical issues that lead to systematic biases. However, few studies investigate the potential for random error or establish expectations for the level of resolution achievable with a given empirical dataset and integrate uncertainties across methods when faced with conflicting results.

Tailoring Mesalazine Nanosuspension Using Chitosan Polyelectrolyte Complexes with Alginate and Alginate/Hydroxypropyl-Methylcellulose Phthalate.

: This study evaluated how the relative proportion of chitosan (CS) to the polyanions alginate (ALG) and hydroxypropyl-methylcellulose phthalate (HP) affects the colloidal properties of mesalazine (MSZ) nanosuspensions as a strategy to produce particles with specific characteristics. : Nanosuspensions were prepared using a bottom-up approach based on acid-base reactions and were modified with CS in a binary mixture with ALG or a ternary mixture with ALG and HP. The particle size, polydispersity index (PDI), zeta potential, morphology, and drug association efficiency were analyzed.
