ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Efficacy of Contrast‐Enhanced Endoscopic Ultrasound in the Diagnosis of Gallbladder Tumor: A Retrospective Multicenter Cohort Study

open access: yesJournal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background and Aims Contrast‐enhanced endoscopic ultrasonography (CE‐EUS) provides clearer visualization of wall layer structures in gallbladder nodules than B‐mode EUS. This study aimed to compare the diagnostic performance of B‐mode EUS and CE‐EUS in differentiating benign from malignant gallbladder lesions.

Peutz-Jeghers syndrome and duodeno-jejunal adenocarcinoma-therapeutic implications [PDF]

open access: yes, 2009
The Peutz-Jeghers syndrome (PJS) is an autosomal dominant hamartomatous poliposis describred in 1921. Hemminki in 1997 described the presence of LKB-1 mutation tumor-suppressor gen.The patients with PJS develop a higher cumulative incidence of ...

Juvenile polyposis in a SMAD4‐mutated child: A call for early surveillance

open access: yesJPGN Reports, EarlyView.
Abstract We report the case of a 10‐year‐old boy with hereditary hemorrhagic telangiectasia (HHT) and a family history of SMAD4‐related juvenile polyposis syndrome (JPS), presenting with hypoferritinaemia unresponsive to oral supplementation. Endoscopic evaluation revealed multiple gastrointestinal polyps, including duodenal, gastric, and colonic ...

A case report of Peutz–Jeghers syndrome in a child with Crohn's disease

open access: yesJPGN Reports, EarlyView.
Abstract Peutz–Jeghers syndrome (PJS) is a rare genetic disorder characterized by hamartomatous polyps and mucocutaneous hyperpigmented freckles, whereas Crohn's disease (CD) is a condition characterized by chronic intestinal inflammation. Here, we present a rare case report of an 11‐year‐old male who presented with both CD and PJS.
