Vasculogenic here mimicry (VM) is a kind of tumor vasculature providing blood supply for tumor growth, and the formation of VM is independent of vascular endothelial cells.Instead, VM structures are formed by differentiated tumor cells such as nasopharyngeal carcinoma cells.Recently, studies have shown that anti-angiogenic therapy failed to improve
An alternative method for obtaining data on pump discharge and head in order enable to determine pump characteristics has been investigated and formulated.Three types of centrifugal pump, the snails house, diffuser and turbine, have been selected.According to their respective manufacturers, the heads of these pumps are 16 m, 11 m and 9 m, respectiv
Functional magnetic resonance here imaging (fMRI) has been extensively used as a tool to map the brain processes related to somatosensory stimulation.This mapping includes the localization of task-related brain activation and the characterization of brain activity dynamics and neural circuitries related to the processing of somatosensory informatio
ABSTRACT Purpose: To identify an optimal self-expandable metallic read more stent (SEMS) and verify whether a mechanically superior SEMS would result in better clinical outcomes in the treatment of tracheal collapse.Methods: We selected three SEMS (n = 8 each), including an S-type stent with a wire diameter of 0.006 inches (S6) and two D-type stent
