CD9/SOX2-positive cells in the intermediate lobe of the rat pituitary gland exhibit mesenchymal stem cell characteristics.

Adult tissue stem cells of the anterior pituitary gland, CD9/SOX2-positive cells, are believed to exist in the marginal cell layer (MCL) bordering the residual lumen of the Rathke's pouch. These cells migrate from the intermediate lobe side of the MCL (IL-MCL) to the anterior lobe side of the MCL and may be involved in supplying hormone-producing cells. Previous studies reported that some SOX2-positive cells of the anterior lobe differentiate into skeletal muscle cells.

Usefulness of Dual-Energy CT for Differentiating Hemorrhage From Iodine Extravasation in Meningiomas After Preoperative Embolization.

Objective: Discriminating between hemorrhage and iodine extravasation can pose challenges in conventional computed tomography (CCT) images following preoperative embolization for meningioma. This study aimed to assess the efficacy of dual-energy computed tomography (DECT) in differentiating hemorrhage from iodine extravasation after preoperative embolization for meningioma.

Methods: Twenty-one consecutive meningioma patients who underwent CCT before and DECT immediately after preoperative embolization were included in this study.

Regulation of Branchial Anoctamin 1 Expression in Freshwater- and Seawater-Acclimated Japanese Medaka, Oryzias latipes.

In euryhaline teleosts, the cystic fibrosis transmembrane conductance regulator (CFTR) in seawater (SW)-type chloride cells facilitates apical Cl secretion for SW adaptation, while alternative Cl excretion pathways remain understudied. This study investigates the role of the calcium-activated chloride channel, Anoctamin 1 (ANO1), in the gills of the euryhaline Japanese medaka (Oryzias latipes) under hyperosmolality and cortisol (CORT) influence. Acclimation to artificial SW, NaCl, mannitol, or glucose significantly upregulated ANO1 and CFTR mRNA expression in gills, unlike urea treatment.

Hyperenhancement of LA Wall by Three-Dimensional High-Resolution Late Gadolinium-Enhanced MRI and Recurrence of AF After Catheter Ablation.

: This study investigated the relationship between LA (LA) enhancement on three-dimensional (3D) late gadolinium enhancement (LGE) MRI and recurrence after catheter ablation in patients with AF (AF). : A total of one hundred patients with AF (mean age: 68 ± 9 years, 50% with paroxysmal AF) were included in this study. Each patient underwent a high-resolution 3D LGE MRI prior to catheter ablation, allowing for detailed imaging of the LA wall.
