Intraabdominal Pressure and Postoperative Discomfort in Laparoscopic Roux-en-Y Gastric Bypass (RYGB) Surgery: a Randomized Study.

High intraabdominal pressure (IAP) during laparoscopic surgery has been associated with postoperative discomfort. Effects on nausea and access have not been subjected to randomized studies. In cholecystectomy, lower IAP may cause less pain, but nausea and surgical access in RYGB surgery have not been investigated. We studied the influence of two IAP levels on surgical access, operation time, posto

Functional importance of estrogen receptors in the periodontium.

The main functions of estrogen are associated with reproduction. However, estrogen has been shown to be of functional importance also in non-classic target organs. Previous studies, especially epidemiologic and clinical ones, have addressed estrogen's influence on periodontitis, suggesting that estrogen has a beneficial effect, but the biological mechanisms have not been identified. Estrogen exert

CD47 regulates collagen I-induced cyclooxygenase-2 expression and intestinal epithelial cell migration.

Increased epithelial cell expression of the cyclooxygenase-2 (COX-2) enzyme is a characteristic event of both inflammatory bowel disease and colon cancer. We here report the novel findings that collagen I-induced de novo synthesis of COX-2 in intestinal epithelial cells is inhibited by pertussis toxin (PTX) and by an inhibitory peptide selective for the heterotrimeric G alpha(i3)-protein. These fi

Use of a T cell interferon gamma release assay in the investigation for suspected active tuberculosis in a low prevalence area.

BACKGROUND: In settings with low background prevalence of tuberculosis (TB) infection, interferon-gamma release assays (IGRA) could be useful for diagnosing active TB. This study aims to evaluate the performance of QuantiFERON-TB Gold (QFT-G) in the investigation for suspected active TB, with particular attention to patients originating in high-incidence countries. Furthermore, factors associated

HAMLET Treatment Delays Bladder Cancer Development.

PURPOSE: HAMLET is a protein-lipid complex that kills different types of cancer cells. Recently we observed a rapid reduction in human bladder cancer size after intravesical HAMLET treatment. In this study we evaluated the therapeutic effect of HAMLET in the mouse MB49 bladder carcinoma model. MATERIALS AND METHODS: Bladder tumors were established by intravesical injection of MB49 cells into poly
