Introduction And Importance: The branchial or pharyngeal apparatus, crucial in embryological development, consists of clefts, arches, pouches, and membranes. Anomalies arising from this apparatus particularly involving the second branchial arch, are rare. Among these anomalies, complete second branchial cleft fistulas, with both external and internal openings, are exceptionally uncommon.

Objectives: In the last two decades, scientists have gained a better understanding of several aspects of pituitary development. The signaling pathways that govern pituitary morphology and development have been identified, and the compensatory relationships among them are now known.

Aims: This paper aims to emphasize the wide variety of relationships between Pituitary Gland and Stem cells in hormone Production and disease prevention.

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

Cell Tissue Res

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.

Introduction: Roux-en-Y gastric bypass (RYGB) reversal might be necessary to alleviate refractory surgical or nutritional complications, such as postprandial hypoglycemia, malnutrition, marginal ulceration, malabsorption, chronic diarrhea, nausea and vomiting, gastro-esophageal reflux disease, chronic pain, or excessive weight loss. The surgical technique of RYGB reversal is not standardized; potential strategies include the following: (1) gastro-gastrostomy: hand-sewn technique, linear stapler, circular stapler; (2) handling of the Roux limb: reconnection or resection (if remaining intestinal length ≥ 4 m).

Case Presentation: We demonstrate the surgical technique of a laparoscopic reversal of RYGB with hand-sewn gastro-gastrostomy and resection of the alimentary limb with the aim of improving the patient's quality of life.

Background: The development of new trans-septal transcatheter interventions for patients with structural heart disease necessitates a precise and comprehensive understanding of the anatomy of the interatrial septum (IAS). The scarcity of gross anatomical studies has triggered our interest in exploring the morphometry and morphology of IAS.

Aims: To study the morphology, morphometry and variations of the interatrial septum in autopsied human hearts.
