Multi-task interaction learning for accurate segmentation and classification of breast tumors in ultrasound images.

In breast diagnostic imaging, the morphological variability of breast tumors and the inherent ambiguity of ultrasound images pose significant challenges. Moreover, multi-task computer-aided diagnosis systems in breast imaging may overlook inherent relationships between pixel-wise segmentation and categorical classification tasks. Approach.

Contrast-enhanced ultrasound of collecting duct carcinoma in the renal: a case report misdiagnosed as renal abscess on computed tomography scan.

Collecting duct carcinoma (CDC), also known as Bellini duct carcinoma, is a rare malignancy with significant challenges in early diagnosis. This paper presents a case report of CDC that was misdiagnosed as renal abscess on computed tomography (CT). A 49-year-old male patient was admitted to the hospital with bilateral lumbar pain, exacerbated on the left side, accompanied by hematuria.

Fabricating Lattice-Confined Pt Single Atoms With High Electron-Deficient State for Alkali Hydrogen Evolution Under Industrial-Current Density.

The confining effect is essential to regulate the activity and stability of single-atom catalysts (SACs), but the universal fabrication of confined SACs is still a great challenge. Here, various lattice-confined Pt SACs supported by different carriers are constructed by a universal co-reduction approach. Notably, Pt single atoms confined in the lattice of Ni(OH) (Pt/Ni(OH)) with a high electron-deficient state exhibit excellent activity for basic hydrogen evolution reaction (HER).

M2 Microglia-Derived Exosomal miR-144-5p Attenuates White Matter Injury in Preterm Infants by Regulating the PTEN/AKT Pathway Through KLF12.

Perinatal white matter injury (WMI), which is prevalent in premature infants, involves M2 microglia affecting oligodendrocyte precursor cells (OPCs) through exosomes, promoting OPC growth and reducing WMI. The molecular mechanism of WMI remains unclear, and this study explored the role of M2 microglia-derived exosomes in WMI. A tMCAO rat model was constructed to simulate WMI characteristics in vivo.
