Background: The node classification outlined in the seventh edition of the tumor-node-metastasis (TNM) classification is based solely on the number of metastasized lymph nodes. We examined the prognostic value of apical lymph node metastasis and the additive value of incorporating apical lymph node status into a risk model based on the seventh edition. Methods: Our cohort study involved 1355 pa...

OBJECTIVE To demonstrate that the seventh edition of the tumor-node-metastasis (TNM) classification for gastric cancer (GC) should be updated with the number of negative lymph nodes for the improvement of its prognostic prediction accuracy. METHODS Clinicopathological data of 769 GC patients who underwent curative gastrectomy with lymphadenectomy between 1997 and 2006 were retrospectively ana...

We resolved the relationships between 2 pandemic clones of Vibrio cholerae. Using 26 housekeeping genes, we showed that the US Gulf clone, the Australian clone, and 3 El Tor strains isolated before the seventh pandemic were related to the seventh pandemic clone. The sixth pandemic clone was well separated from them.

OBJECTIVE To compare the effects of deep breathing exercises (DBE) and the flow-oriented incentive spirometry (IS) in patients undergone coronary artery bypass grafting (CABG) through the following variables: forced vital capacity - FVC, forced expiratory volume in 1 second - FEV(1), maximal respiratory pressures and oxygen saturation. METHODS Thirty six patients in CABG postoperative period ...

serum ige and beta 2 microglobulin levels were determined in 31 patients suffering from acute myocardial infarction and 30 patients with other forms of ischemic heart disease. the levels of these parameters were studied on the first, third and seventh day after the onset of disease. the immunological method used for the determinations was elisa patients with myocardial infarction showed an elev...
