Interstitial fluid pressure, interstitial velocity and related parameters are of great clinical significance for cancer diagnosis, prognosis treatment. A limited number non-invasive techniques can be used to estimate these mechanopathological in cancers vivo. In this study, we designed tested new ultrasound poroelastography methods capable estimating the magnitude spatial distribution flow insi...

The interstitial fluid transport plays an important role in terms of its effect on the delivery of therapeutic agents to the cancerous organs. In this study, a comprehensive numerical simulation of the interstitial fluid transport establishing 3D models of tumor and normal tissue is accomplished. Different shapes of solid tumors and their surrounding normal tissues are selected, by employing th...

Shedding of cell surface antigens is an important biological process that is used by cells to modulate responses to signals in the extracellular environment. Because antibody-based therapies of cancer target cell surface antigens, it is important to understand more about the shedding process and how it affects tumor responses to this type of therapy. Up to now most attention has been focused on...

background and objective: p53 is a suppressive gene that plays a key role in dna repair and apoptosis. the purpose of this study was to investigate the effect of p53 protein over-expression and some clinicopathological factors on the esophageal squamous cell carcinoma (scc) response to neoadjuvant chemoradiotherapy. patients and methods: in this retrospective cohort study, 44 patients with loca...

introdouction: squamous cell carcinoma is the most common oral cancer and the prognosis because of a late diagnosis remains poor despite numerous treatments. therefore, we conducted a cross-sectional study to investigate the relationships between survival rate(sr) of oral squamous cell carcinoma (oscc) and clinical,demographic, pathological, and molecular factors in yazd city during 1998– 2008....

conclusions despite the fact that abnormalities in p53 and p27kip1 may be involved in the development of oscc, their clinical significance in the studied population seems limited. further investigation on the combined p53/p27kip1 expression may be helpful in predicting the biologic behavior of this tumor. results p53 and p27kip1 expression were found in 28.57% (8 positive versus 20 negative) an...
