Cross-laboratory replication of pseudomyxoma peritonei tumor microbiome reveals reproducible microbial signatures.

Recent work has demonstrated that cancer-specific microbial communities often colonize tumor tissues. However, untangling low-biomass signals from environmental contamination makes this research technically challenging. We utilize pseudomyxoma peritonei (PMP), a cancer characterized by the spread of mucus-secreting cells throughout the peritoneal cavity, to develop a robust workflow for identifying reproducible tumor microbiomes.

Microarray patches likely to reduce the operational costs of immunization: A Monte Carlo simulation study.

Development of microneedle array patches (MAPs) for potential use in immunization is ongoing, but the cost of manufacturing is expected to be higher than that of existing needle-and-syringe vial systems. The potential benefits of MAPs in reaching previously unvaccinated populations have been touted, but affordability, especially in low- and middle-income countries, remains an open question. In this study, we quantify the expected impact on operational costs of switching to MAPs for immunization for measles-rubella, human papilloma virus, and typhoid in both routine and campaign-based delivery modes.

Gratitude for Bystander Action Varies by Peer Intervention and Social Norms.

Gratitude is associated with increased social integration, which may counter the loneliness stemming from repeated peer victimization. The gratitude youth feel after different types of bystander action may depend on which behaviors are most congruent with personal beliefs. Face and honor cultures provide social norms for expectations and interpretations of behavior, including how to act during and after interpersonal conflict.

Curvature Perception of Mesenchymal Cells on Mesoscale Topographies.

Cells can sense geometrical cues with sizes of several tens of micrometers in their vicinity. Recent in vitro studies show that cells can adapt their shape, align along specific directions, or regulate other cellular functions when grown on surfaces with curvatures larger than their size. Although possible mechanisms for such responses like the alignment along axial cues have been suggested, a detailed understanding of the involved cellular processes remains open.
