Calcium, light and the adaptable topography of pectin in the cell wall of the streptophyte alga, Penium margaritaceum​

This study demonstrates that the pectin lattice of the streptophyte alga *Penium margaritaceum* exhibits adaptable topography influenced by calcium levels and light-driven carbon availability, revealing dynamic recovery mechanisms and banding patterns that serve as a model for understanding plant cell wall dynamics.

Toward the use of simulated environments to evaluate sEMG-informed knee-angle prediction: RMSE predicts simulated instability only above a threshold error

This study demonstrates that while sEMG-informed knee-angle prediction improves numerical accuracy (RMSE), this improvement does not linearly correlate with reduced simulated instability, as the relationship between error and stability inverts below a threshold of approximately 13°, indicating that lower RMSE values do not universally guarantee more stable motion in the tested regime.

Rapid metabolism of the immuno-PET radioligand [68Ga]Ga-NOTA-GZP upon in vivo administration in mice

Despite demonstrating excellent stability in human plasma, the immuno-PET radioligand [68Ga]Ga-NOTA-GZP undergoes rapid in vivo metabolism in mice, leading to significant degradation and distinct biodistribution patterns that necessitate cautious interpretation of imaging data and improved chelation strategies.

Distinct Evolutionary Selection Patterns in Temperate and Filamentous Phages of Phocaeicola vulgatus in Health and IBD

This study reveals that inflammation in Crohn's disease imposes distinct evolutionary selection pressures on *Phocaeicola vulgatus* phages, causing a loss of genetic diversity in tailed phages and a shift in diversification patterns for filamentous phages, thereby highlighting the complex dynamics between phages, bacteria, and the human host in health and disease.

Facial region-specific visual attention in children with attention-deficit/hyperactivity disorder: an eye-tracking study

This eye-tracking study reveals that children with ADHD exhibit distinct facial region-specific attention patterns during emotional face viewing, characterized by quicker attention to the mouth and prolonged focus on the nose, rather than a generalized avoidance of the eye region.

Piezo1-ADAM axis promotes inflammatory alveolar-capillary crosstalk resulting in transendothelial leukocyte migration

This study reveals that mechanical stress-induced activation of the Piezo1 ion channel in lung epithelial cells triggers the release of ADAM protease-dependent inflammatory factors, which subsequently activate endothelial cells to promote leukocyte transmigration across the alveolar-capillary barrier.

Phylogenetic and Genomic Analysis of Multi-resistance in Salmonella Enterica

This study analyzes 20 African *Salmonella enterica* genomes to reveal that multidrug resistance is driven by a complex interplay of regional phylogenetic history, horizontal gene transfer, and the co-selection of antibiotic resistance by environmental biocides and heavy metals, necessitating a unified One Health approach for mitigation.
