Microbial carbon use efficiency (CUE) regulates the partitioning of organic carbon between microbial biomass and CO(2) emission, yet its response to climate warming remains poorly understood, especially in naturally regenerating ecosystems like abandoned croplands. Here, we conducted 3 year in situ warming experiments (+1.6 °C) across 12 abandoned cropland sites spanning arid to humid climatic zones in China. Using the ^(18)O-H(2)O method and molecular characterization, we found that warming...

CONCLUSIONS: Possible lower LRF and less acute toxicity with cetuximab versus cisplatin for KRAS-variant patients appear to be offset by potentially increased late toxicity. Further evaluation of this class of biomarkers is warranted.

CONCLUSION: These results provide educators with a set of practical competencies to measure prelicensure student knowledge, skills, and attributes, thereby advancing health equity education.

CONCLUSIONS: Medical school COI policies remain less stringent than consensus recommendations; thus, renewed attention to policies and implementation is needed to ensure bias-free medical education.
