To address these challenges, we propose UltraNet, a state-of-the-art lightweight model that achieves competitive performance in segmenting multiple parts of medical images with the lowest parameters and computational complexity.

The neural basis of self-ambivalence: an ERP study.

The primary objective of this study was to investigate the neural basis of self-ambivalence, a phenomenon firmly established by behavioral research but whose underlying brain mechanisms have been less explored. Employing EEG methods and a modified self-reference paradigm, we analyzed event-related potentials using a linear mixed model to determine whether self-ambivalence processing exhibits a distinct neural representation. The results indicated that self-ambivalence processing primarily affected the late components (N2, N450, and P3), with N450 activation in the midline brain regions showing a significant positive correlation with scores on the Dialectical Self Scale.

CDC20-Mediated Selective Autophagy Degradation of PBRM1 Affects Immunotherapy for Renal Cell Carcinoma.

Polybromo 1 (PBRM1) inactivating mutations are associated with clinical benefit from immune checkpoint inhibitor treatments in clear cell renal cell carcinoma (ccRCC). However, whether targeting PBRM1 has the potential to enhance immunotherapy efficacy in patients with wild-type PBRM1 and the upstream pathways that regulate PBRM1 protein stability remain unclear. Here, it is demonstrated that PBRM1 knockdown induced M1 macrophage polarization and infiltration, which enhanced the efficacy of anti-PD-1 immunotherapy in RCC.
