Article Synopsis
- - The transition of tetrapods to terrestrial ecosystems around 375 million years ago marked a significant evolutionary step, driven by adaptations like the development of a tympanic ear that improved sound detection in air.
- - Earlier theories claimed a single evolutionary origin for the tympanic ear in tetrapods, but recent studies indicate it evolved independently in amphibians, mammals, and reptiles, though it’s unclear how many times this occurred within reptiles.
- - New research combines developmental and paleontological insights, suggesting that the tympanic membrane was likely present in a common ancestor of crown reptiles, arguing for a single evolutionary origin rather than multiple instances for tympanic hearing in modern reptiles.
Article Synopsis
- Endoscopic submucosal dissection (ESD) is a minimally invasive method for removing superficial gastrointestinal lesions, with reported variations in quality between East and West.
- This study analyzed the effectiveness and safety of ESD in a cohort of 111 patients at an Italian center, focusing on outcomes like technical success and resection rates.
- Results showed high technical success and R0 resection rates, indicating that ESD is a viable option for treating superficial GI lesions in Western patients, although some major adverse events were noted.
A 61-year-old man with alcoholic cirrhosis and a history of severe cholecystitis leading to secondary thrombosis of the recanalized paraumbilical vein was admitted to our hospital for recurrent gastrointestinal bleeding and severe anemia. Capsule endoscopy and CT angiography detected profuse bleeding in the proximal ileum from ectopic ileal varices. Hepatic venous-portal gradient (HVPG) measurement was consistent with severe portal hypertension.
