Endoscopic submucosal dissection in the treatment of adult cystic lymphangioma: A case report.
World J Gastrointest Surg
January 2025
Department of Gastroenterology, The Affiliated Hospital, Southwest Medical University, Luzhou 646000, Sichuan Province, China.
Background: Cystic lymphangioma is a rare hamartoma that is especially found in the adult gastrointestinal tract. In the early stage, most patients are asymptomatic; after the onset of symptoms, there is often no specificity regarding symptoms.
Case Summary: Here we report the endoscopic diagnosis and treatment of an adult patient with cystic lymphangioma of the ascending colon.
Protease-activated receptor 1 in the pathogenesis of cystic fibrosis.
BMJ Open Respir Res
January 2025
Murdoch Children's Research Institute, Parkville, Victoria, Australia.
Background: The most common cause of death in those with cystic fibrosis (CF) is respiratory failure due to bronchiectasis resulting from repeated cycles of respiratory infection and inflammation. Protease-activated receptor 1 (PAR1) is a cell surface receptor activated by serine proteases including neutrophil elastase, which is recognised as a potent modulator of inflammation. While PAR1 is known to play an important role in regulating inflammation, nothing is known about any potential role of this receptor in CF pathogenesis.

Cystic Fibrosis (CF) is a life-shortening disease that is caused by mutations in the CFTR gene, a gene that is expressed in multiple organs. There are several primary tissue models of CF disease, including nasal epithelial cultures and rectal organoids, that are effective in reporting the potential efficacy of mutation-targeted therapies called CFTR modulators. However, there is the well-documented variation in tissue dependent, therapeutic response amongst CF patients, even those with the same CF-causing mutation.

November 2024
Medicine and Surgery, Chittagong Medical College, Chittagong, BGD.
Gastrointestinal bleeding resulting from the involvement of the gastrointestinal tract in people with Klippel-Trenaunay syndrome (KTS) is exceedingly uncommon and frequently neglected. A 22-year-old male, a diagnosed case of KTS, was assessed for per rectal bleeding and abdominal discomfort. A colonoscopy revealed third-degree hemorrhoids with vascular malformation all over the colon.

Secretory diarrhea, a major global health concern, particularly among young children, is often characterized by excessive chloride secretion through the cystic fibrosis transmembrane conductance regulator (CFTR) channel. Nornidulin, a fungus-derived natural product from Aspergillus unguis, has previously been shown to inhibit cAMP-induced Cl- secretion in T84 cells (human intestinal cell lines). However, the cellular mechanism of nornidulin in inhibiting cAMP-induced Cl- secretion and its anti-secretory efficacy is still unknown especially in a human colonoid model, a preclinical model recapitulating intestinal physiology in humans.
