Connexin 37, 40, 43 and Pannexin 1 Expression in the Gastric Mucosa of Patients with Systemic Sclerosis.

Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and internal organs. Although its pathogenesis is not fully understood, connexins (Cxs) and pannexins (Panx) could be involved in the process of fibrosis. We analyzed the protein expression of Cx37, Cx40, Cx43, and Panx1 in the gastric mucosa of patients with SSc and healthy volunteers, using immunofluorescence staining.

Obstructive Giant Inflammatory Polyposis as a First Manifestation of Crohn's Disease: A Case Report.

Colonic inflammatory polyps (pseudopolyps) are common feature of inflammatory bowel diseases. They usually do not grow excessively, rarely reaching more than 15 mm in size, at which point they are termed giant inflammatory polyps.
