Targeted Delivery of Indole‐3‐Pyruvic Acid Suppresses Macrophage Ferroptosis to Enhance CD8+ T Cell‐Mediated Immunotherapy Response in Bladder Cancer

open access: yesAdvanced Science, EarlyView.
A microbiota‐derived metabolite, indole‐3‐pyruvic acid, suppresses macrophage ferroptosis through the AHR–NF‐κB–SLC7A11 axis. This preserves CD8+ T cell function in bladder cancer. Macrophage‐targeted nanoparticles enhance indole‐3‐pyruvic acid delivery and overcome resistance to PD‐1 blockade.

Honey bees performing varroa sensitive hygiene remove the most mite-compromised bees from highly infested patches of brood [PDF]

open access: yesApidologie, 2018
Varroa destructor is a key contributor to honey bee (Apis mellifera L.) colony losses that threaten global economies. Some colonies, especially those displaying high levels of hygiene behaviour targeted towards V. destructor-infested cells, survive mite infestation.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...

Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

The Worker Flow at the Hive Entrance Predicts When Nest Cleaning is Intensified in Stingless Bees

open access: yesPsyche: A Journal of Entomology
Waste produced by living organisms is commonly disposed of as a prophylactic measure to avoid the spread of diseases and parasite infestation. For social insects, a proportion of workers is allocated to dispose the waste material outside the colony’s ...
