Colorectal cancer (CRC) usually creates an immunosuppressive microenvironment, thereby hindering immunotherapy response. Effective treatment options remain elusive. Using scRNA-seq analysis in a tumor-bearing murine model, it is found that lobeline, an alkaloid from the herbal medicine lobelia, promotes polarization of tumor-associated macrophages (TAMs) toward M1-like TAMs while inhibiting their polarization toward M2-like TAMs.

Methods: A total of 400 and 400 snails were collected from Yongsheng County, Yunnan Province in June 2024, and snail images were captured following identification and classification of 300 and 300 snails. A total of 925 images and 1 062 snail images were collected as a dataset and divided into a training set and a validation set at a ratio of 8:2, while 352 images captured from the remaining 100 and 354 images from the remaining 100 snails served as an external test set.
Background: Understanding sleep problems in late adolescents caused by daily stress is essential due to their increased vulnerability to stress-related sleep issues. While previous research has demonstrated the potential protective effect of trait mindfulness, facets of mindfulness were found to have unique functions against the negative impact of stress, and the unique impact of each facet of mindfulness on the sleep problems caused by the negative impact of stress remains unclear. Thus, this longitudinal study aimed to assess the impact of stressful life events on sleep problems a year later among late adolescents and to explore the moderating effects of the five trait mindfulness facets.

The development and generation of affordable and highly efficient energy, particularly hydrogen, are one of the best approaches to address the challenges posed by the depletion of non-renewable energy sources. Hydrogen energy, as a green and ecosystem-friendly source with zero carbon emission, can be generated through various methods, including water splitting (HER/OER) either photo- or electrocatalytic reactions. To implement these reactions effectively in practical applications, it is highly desirable to develop extremely efficient and cost-effective catalytic materials that are comparable to contemporary catalysts.
