Rhizomorphs are hair- or wire-like melanized structures with structural differentiation analogous to plant roots that help fungi spread over an area and find food resources. Some species of multiple groups of the and the produce different types of rhizomorphs. In the , the structures are largely found in , particularly in the , , and .

Article Synopsis
- The transmembrane potential is crucial for cellular functions like signaling and energy production, with Rhodamine voltage reporters (RhoVRs) serving as small, non-invasive sensors that can detect voltage changes, especially in mitochondria.
- Extensive simulations and free-energy calculations revealed that the orientation of RhoVRs relative to membranes, influenced by their polarized functional groups, significantly impacts their voltage sensitivity and localization within cells.
- The study's findings on the relationship between the chemical structure of RhoVRs and their membrane behavior offer valuable insights for designing fluorescent dyes that better detect voltage changes.
Ultrasonographic accuracy in evaluating response of clipped lymph nodes in targeted axillary dissection in breast cancer.

This study aimed to evaluate the diagnostic accuracy of ultrasonography in assessing the response of clipped axillary lymph nodes to neoadjuvant chemotherapy. Between February 2022 and September 2023, 43 patients who underwent axillary lymph node marking for targeted axillary dissection were retrospectively analyzed. Ultrasonography parameters such as the number, size, shape, cortical thickness, hilum status, and treatment response of the clipped lymph node were assessed.

Accidental bending of the snare sheath occasionally occurs during cold snare polypectomy (CSP). We aimed to demonstrate whether snare bending reduces resection ability and, if it does, what causes this reduction. Using currently available CSP snares and prototype snares, we investigated changes in the resection ability of bent snares as well as the stiffness of their sheaths and wire spindles.
