Ascitic autotaxin as a potential prognostic, diagnostic, and therapeutic target for epithelial ovarian cancer.

Background: Malignant ascites contributes to the metastatic process by facilitating the multifocal dissemination of ovarian tumour cells onto the peritoneal surface. However, the prognostic and diagnostic relevance of ascitic fluid remains largely unknown. Herein, we investigated the potential clinical value and therapeutic utility of ascitic autotaxin (ATX) in epithelial ovarian cancer (EOC).

Clinical Significance of Tumor Infiltrating Lymphocytes in Association with Hormone Receptor Expression Patterns in Epithelial Ovarian Cancer.

Hormone receptor expression patterns often correlate with infiltration of specific lymphocytes in tumors. Specifically, the presence of specific tumor-infiltrating lymphocytes (TILs) with particular hormone receptor expression is reportedly associated with breast cancer, however, this has not been revealed in epithelial ovarian cancer (EOC). Therefore, we investigated the association between hormone receptor expression and TILs in EOC.

ALDH1A2 Is a Candidate Tumor Suppressor Gene in Ovarian Cancer.

Aldehyde dehydrogenase 1 family member A2 (ALDH1A2) is a rate-limiting enzyme involved in cellular retinoic acid synthesis. However, its functional role in ovarian cancer remains elusive. Here, we found that ALDH1A2 was the most prominently downregulated gene among ALDH family members in ovarian cancer cells, according to complementary DNA microarray data.

Staphylococcal enterotoxins A and B enhance rhinovirus replication in A549 cells.

Background: Staphylococcal enterotoxin A (SEA) and staphylococcal enterotoxin B (SEB) have been reported to be important in the pathogenesis of chronic rhinosinusitis (CRS). To elucidate the pathophysiological responses in the nasal mucosae of CRS patients associated with rhinovirus (RV) infection, we investigated the effects of SEA and SEB on RV infection in A549 cells.

Methods: Changes in expression of intercellular adhesion molecule (ICAM) 1 were assessed by flow cytometry, and effects on cytokine secretion were measured by ELISA.

Detection of rhinovirus in turbinate epithelial cells of chronic sinusitis.

Background: In contrast to the well-established association of rhinovirus (RV) with acute sinusitis, little is known about the role of RV infections in the pathogenesis of chronic sinusitis. Therefore, we assayed the nasal cavity mucosae of chronic sinusitis patients lacking signs of acute viral infection for the presence of RV.

Methods: Nasal lavage fluids and turbinate epithelial cells from 39 sinusitis patients and 27 control subjects were tested.

The effect of hyperbaric oxygen on ischemia-reperfusion injury: an experimental study in a rat musculocutaneous flap.

The effect of hyperbaric oxygen is known to increase survival of ischemic tissue but its mechanism is not fully understood. The purpose of this study was to evaluate the effect of hyperbaric oxygen on a rat musculocutaneous flap versus ischemia-reperfusion injury, focusing on the mechanism involving the expression of adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) of endothelial cells and CD18 of neutrophils. A transverse rectus abdominis musculocutaneous (TRAM) flap (6 x 5 cm) supplied by a single superior epigastric vascular pedicle was elevated in 100 Sprague-Dawley rats.
