Ribes diacanthum Pall modulates bile acid homeostasis and oxidative stress in cholestatic mice by activating the SIRT1/FXR and Keap1/Nrf2 signaling pathways.

Ethnopharmacological Relevance: Cholestatic liver injury (CLI) is a pathophysiological syndrome characterized by the accumulation of bile acids (BAs), which leads to significant hepatic dysfunction. This condition is frequently associated with disturbances in BAs homeostasis and the induction of oxidative stress. Ribes diacanthum Pall (RDP), a conventional folk medicinal plant, has been employed in Mongolia, the Inner Mongolia region of China, and other areas for the remediation of hepatic disorders.

Circadian and Autophagy Markers Correlate with Poor Prognosis in Meningioma Patients.

Purpose: Patients with meningiomas mostly present good outcomes and optimal prognosis, but different grades of tumors have very different symptoms and recurrence rates. Therefore, effective diagnosis is crucial for early intervention and controlling tumor development. Circadian cycle and autophagy have both been proven to be related to neoplasm formation and pathogenesis; however, there is limited exploration and discussion on the relationships between the circadian cycle and autophagy in patients with meningiomas.

Skull Impact on Photoacoustic Imaging of Multi-Layered Brain Tissues with Embedded Blood Vessel Under Different Optical Source Types: Modeling and Simulation.

Skulls with high optical scattering and acoustic attenuation are a great challenge for photoacoustic imaging for human beings. To explore and improve photoacoustic generation and propagation, we conducted the photoacoustic simulation and image reconstruction of the multi-layer brain model with an embedded blood vessel under different optical source types. Based on the optical simulation results under different types of optical sources, we explored the characteristics of reconstructed images obtained from acoustic simulations with and without skull conditions.

Assessment of Outcomes & Anatomical Changes in the Upper Urinary Tract following Flexible Ureteroscopy with a Flexible and Navigable Suction Ureteral Access Sheath (FANS): 3-Month Results from a Multicenter Study.

Objectives: To study the long-term outcomes of the flexible and navigable suction ureteral access sheath (FANS) in flexible ureteroscopy (FURS). FANS has well-established efficiency and 30-day perioperative safety; however, its influence on pelvicalyceal and ureteric anatomy remains to be investigated.

Methods: This was a prospective study of patients with normal renal anatomy who underwent FURS with FANS for renal stones from April 2023 to August 2024 in 16 centers worldwide.
