Objectives. Zollinger-Ellison Syndrome (ZES) results in hypersecretion of gastric acid (via gastrinoma) leading to peptic ulcers, diarrhea, and abdominal pain. We describe the novel discovery of hypertrophic, heterotopic gastric mucosa in the proximal duodenal bulb in patients with ZES, which we hypothesize results in an increased incidence of postbulbar ulcers in patients with ZES (a mechanism...

The intestinal epithelium acts as a selective barrier for the absorption of water, nutrients and orally administered drugs. To evaluate gastrointestinal permeability candidate molecule, scientists drug developers have multitude cell culture models at their disposal. Static transwell cultures constitute most extensively characterized in vitro system can accurately categorize molecules into low, ...

Objective: Knowledge on timelines of structural and histological development fetal stomach helps in the diagnosis abnormalities (duplication cyst pylorus, heterotopic pancreatic tissue, etc.,) weighing interventions as an option. The present study was undertaken to establish developmental process (e.g., appearance curvatures, gastric pit, glands, various cell types) correlating with gestational...

We evaluated the incidence of heterotopic ossification following total ankle replacement to determine whether the degree of ossification was associated with the clinical outcome. We evaluated 90 ankles in 81 consecutive patients who underwent total ankle replacement, and heterotopic ossification was assessed according to proportional involvement of the ankle joint. Correlation analysis was used...

Background. The problem of gastrointestinal diseases in children remains quite relevant due to the high prevalence and presence atypical symptoms comorbidities pathogenetically associated with acid-dependent diseases. purpose was study dynamics inflammatory changes mucous membrane duodenal ulcer (DU). Materials methods. One hundred six aged 10 18 years DU were examined. To verify diagnosis, all...

Microplastics are practically ubiquitous and pose a serious survival challenge for many species. Most of the exposure experiments determining toxicological effects microplastics were performed with microplastic varying little in shape size (often purchased beads), but few studies deal non-homogeneous samples. We analyzed effect on Xenopuslaevis larva early development polyester fibers, PEFs, ta...

OBJECTIVES Results of tracheal transplantation have been disappointing due to of ischaemia and rejection. It has been experimentally demonstrated that results of tracheal autograft/allograft transplantation were correlated with both graft length and revascularization method. Recently, we demonstrated that heterotopic epithelium-denuded-cryopreserved tracheal allograft (TA) displayed satisfactor...

Background and Aim: Ovarian torsion is one of the rare causes of emergency surgeries during pregnancy. Heterotopic pregnancy is a rare type of pregnancy characterized by embryo implantation in two different locations. occurence of these two complications at the same time is a very rare condition. In this study, we present a rare case of heterotopic pregnancy accompanied by ovarian torsion. Pat...

In the present study, we aimed to determine localization and distribution of entero-endocrine cells in gastrointestinal tract by immunohistochemical methods understand structure glycoproteins elaborated epithelium digestive regions histochemical methods. The nine sparrowhawks were euthanized, tissues removed fixed formalin. sections stained with techniques evaluate enteroendocrine histomorphome...

lipomas are rare gastric tumors that comprise less than 1% of gastric tumors. these tumors are usually without clinical manifestations, but sometimes they may present with severe symptoms like bleeding,intussusception, or abdominal pain. in endoscopic assessment, they manifest with subm ucosal masses with intact epithelium. endosonography and ct scan can help in diagnosis. surgical resection of...
