The principle of the model is a dissection of an idealized invasion process into invasion steps and stages (INVASS model). The basic structure can be depicted as a staircase: five invasion stages (0 to 4) are connected through four invasion steps (1 to 4). The stages describe the status of the species during the invasion, whereas the steps illustrate the processes. The invasion steps summarize ...

The paper develops a simple economic model of a biological invasion. The natural growth of the invasion is non-convex and the immediate cost of controlling the invasion depends on the level of current control as well as the current size of the invasion. Greater control raises control costs today while reducing damages now and in the future. In addition, by decreasing the size of the invasion, i...

conclusions abnormal e-cadherin expression is a common phenomenon in gastric adenocarcinoma. the study showed a significant correlation between abnormal e-cadherin expression and tumor grade and regional lymph node involvement; so, abnormal e-cadherin expression may be used as a predictive factor for tumor invasiveness in gastric adenocarcinoma. materials and methods a historical cohort survey ...

tumor angiogenesis shown by microvessel count (mvc) or microvessel density (mvd), is assessed by several studies as prognostic factor in some types of tumors, and also in colorectal carcinoma. this article is payed to correlation between clincopathologic factors and tumor angiogenesis. in this study, immunohistochemical techniques are used for vascular evaluation in specimens from twenty-nine c...
