Macrophage Notch1 signaling modulates regulatory T cells via the TGFB axis in early MASLD.
JHEP Rep
January 2025
Department of Pharmacology, Wuhan University TaiKang Medical School (School of Basic Medical Sciences), Wuhan 430071, China.
Background & Aims: Hepatic immune imbalance is crucial for driving metabolic dysfunction-associated steatotic liver disease (MASLD) progression. However, the role of hepatic regulatory T cells (Tregs) in MASLD initiation and the mechanisms responsible for their change are not completely understood.
Methods: A mouse model subjected to a short-term high-fat diet (HFD) to mimic early steatosis, along with liver biopsy samples from patients with simple steatosis, and macrophage-specific Notch1-knockout mice (Notch1), were used to investigate the role of Tregs in early MASLD and the effect of hepatic macrophage Notch1 signaling on Treg frequency.
Deep denoising approach to improve shear wave phase velocity map reconstruction in ultrasound elastography.

Department of Electronics and Electrical Engineering, Indian Institute of Technology Guwahati, Assam, India.
Background: Measurement noise often leads to inaccurate shear wave phase velocity estimation in ultrasound shear wave elastography. Filtering techniques are commonly used for denoising the shear wavefields. However, these filters are often not sufficient, especially in fatty tissues where the signal-to-noise ratio (SNR) can be very low.

Institute of Precision Medicine, Peking University Shenzhen Hospital, 518036, Shenzhen, China. Electronic address:
Radiotherapy, employing high-energy rays to precisely target and eradicate tumor cells, plays a pivotal role in the treatment of various malignancies. Despite its therapeutic potential, the effectiveness of radiotherapy is hindered by the tumor's inherent low radiosensitivity and the immunosuppressive microenvironment. Here we present an innovative approach that integrates peroxynitrite (ONOO)-mediated radiosensitization with the tumor-associated neutrophils (TANs) polarization for the reversal of immunosuppressive tumor microenvironment (TME), greatly amplifying the potency of radiotherapy.

Our study intended to explore Hesp antioxidant and anti-inflammatory effects against TAA hepatic fibrosis in rats. Hesperidin (Hesp), is a pharmacologically active flavonoid, found abundantly in citrus species. Our present research attempts to inspect the potential hepatoprotective role of Hesp against thioacetamide (TAA)-induced hepatic fibrosis.

J Med Internet Res
December 2024
Hansung University, Seoul, Republic of Korea.
Background: As health care continues to evolve with technological advancements, the integration of artificial intelligence into clinical practices has shown promising potential to enhance patient care and operational efficiency. Among the forefront of these innovations are large language models (LLMs), a subset of artificial intelligence designed to understand, generate, and interact with human language at an unprecedented scale.
Objective: This systematic review describes the role of LLMs in improving diagnostic accuracy, automating documentation, and advancing specialist education and patient engagement within the field of gastroenterology and gastrointestinal endoscopy.
