Unstirred suspensions of erythrocytes form stable spherical aggregates of uniform size. The radius of the spheres depends upon the suspending medium and the hematocrit. Erythrocyte suspensions will undergo sedimentation only after these aggregates are formed. Aggregation is a two-step process: first, erythrocytes associate in long chains (rouleau formation). Next, these chains form spheres of u...

PURPOSE Chronic inflammation induces cancer and cancer induces local tissue damage with systemic inflammation. Therefore, the aim of this study is to investigate the potential relationship between the severity of inflammation and prognosis in cancer patients. MATERIALS AND METHODS This study enrolled 220 patients from January 2002 to December 2006 who underwent gastric surgery. We evaluated t...

The paper examines sediment yield and its response to catchment disturbance and environmental variables in the Upper Ž . Yangtze basin, where the attention of environmentalists has been drawn to the Three Gorges Project TGP . Information about the source and conveyance of sediment from the catchment area to the Three Gorges Reservoir has implications for management strategies. Methodologies for...
