AIM Because the presence or absence of H pylori infection has important implications for therapeutic decisions based on histological assessment, the reproducibility of Sydney system is important. The study was designed to test the reproducibility of features of Helicobacter pylori gastritis, using the updated Sydney classification. METHODS Gastric(More)
Peroxynitrite is involved in the pathogenesis of pulmonary diseases such as asthma, occupational pulmonary diseases and acute respiratory distress syndrome (ARDS) due to excessive production of nitric oxide or superoxide or both. Lornoxicam, a new oxicam derivative, is a potent anti-inflammatory agent. In this study, we evaluated the role of lornoxicam in a(More)
Metastases to the supraclavicular fossa usually originate from head and neck or infraclavicular tumors. Ovarian primaries of supraclavicular metastases are very rare. Sex cord stromal tumors of the ovary account for 5-8% of all ovarian malignancies and there have been only a few case reports on distant metastases from these tumors. A 46-year-old woman(More)
Indirect acute lung injury is associated with high morbidity and mortality. We investigated the link between Rho kinase (ROCK) activation and apoptotic cell death in sepsis induced acute lung injury. This hypothesis was tested by administering a specific, selective inhibitor of ROCK (Y-27632) to rats subjected to cecal ligation and puncture (CLP). Rats were(More)
Tuberculosis of the larynx and hypopharynx is an uncommon entity and rarely considered in the differential diagnosis of the laryngo-pharyngeal diseases. We describe a case of a 40-year-old man with tuberculous involvement of the aryepiglottic fold and medial wall of the sinus pyriformis mimicking a malignancy. Current literature concerning the clinical,(More)
The sterile sponges may lose a significant amount of lint during their routine use in surgery, which is usually neglected. We designed an experimental model to evaluate the potential of sterile sponges to lose lint and to induce foreign body reaction in surgically created wounds. In 15 Wistar rats, separate subcutaneous pockets were created. Left-sided(More)
CD44 and beta-catenin are adhesion molecules expressed on a wide variety of cells. Failure of this expression is believed to lead to disruption of cell-cell adhesion and to neoplasia. The aim of this study was to investigate the staining intensity of CD44 and beta-catenin in keratoacanthomas and squamous cell carcinomas of the skin. The proliferation index,(More)
BACKGROUND Preoperative diagnosis of ovarian cancer is still problematic as multiple disease processes may present with pelvic mass. Fascioliasis is a parasitic disease producing unique clinical manifestations. CASE REPORT A 49-year-old female patient admitted to our hospital with the complaint of occasional abdominal pain. Pelvic examination revealed a(More)
