Keck Medicine of USC has launched a clinical trial to evaluate whether a blood test can help detect breast cancer earlier than mammograms alone.

Researchers from Capital Medical University, Beijing, China, have identified a CaN/NFATC3/Id3/E2A/Bmp4 signaling pathway that helps explain how low-intensity pulsed ultrasound (LIPUS) promotes bone regeneration. Id3 was identified as a molecular “brake” that limits LIPUS-induced osteogenesis and was significantly downregulated following ultrasound stimulation. The researchers developed an Id3 inhibitory peptide, rID3, which, when combined with LIPUS, enhanced osteogenesis and bone-defect healing in mice, suggesting a potential strategy for improving ultrasound-based bone regeneration.

A collaborative research team from the University of Electronic Science and Technology of China and the Hangzhou Institute of Medicine of the Chinese Academy of Sciences, proposed a novel self-supervised reconstruction framework that decouples measurement sampling resolution from reconstruction grid density to address the trade-off between sampling and imaging in single-pixel imaging. The framework enables high-pixel-resolution reconstruction from the low-dimensional measurements, providing a new strategy for overcoming resolution limitations in conventional single-pixel imaging.

Heart failure (HF) alters the bone marrow (BM), reducing protective cells that regulate inflammation, reports a study conducted at Science Tokyo. According to the study, cardiac stress reduces a population of mesenchymal stromal cells that produces heparin-binding EGF-like growth factor. The resulting reduction in protective signaling alters blood-forming stem cells and promotes inflammatory macrophages. The findings identify the BM niche as an important regulator of lasting immune changes associated with HF, suggesting potential targets for future therapies.
