| 1 | Expression of cell adhesion molecule CD44 in gastric adenocarcinoma and its prognostic importance显示文摘AIM: To evaluate the relation of cluster of differentiation 44 (CD44) expression with clinicopathological features of gastric adenocarcinoma, and also its effect on prognosis with an emphasis on the differences between intestinal and diffuse types. METHODS: From 2000 to 2006, 100 patients with gastric adenocarcinoma, who had undergone total or subtotal gastrectomy without any prior treatment, were studied. Haematoxylin & eosin (HE) staining was used for histological evaluation, including the type (Lauren's classifi cation) and grading of the tumor. The expression of CD44 in the gastric adenocarcinoma mucosa and the adjacent mucosa were determined by immunohistochemistry. The survival analysis was obtained using the Kaplan-Meier test. RESULTS: Of 100 patients, 74 (74%) patients were male. The tumors were categorized as intestinal type (78%) or diffuse type (22%). Sixty-five percent of patients were CD44-positive. CD44 expression was not detected in normal gastric mucosa. Rather, CD44 was more commonly expressed in the intestinal subtype (P = 0.002). A signifi cant relation was seen between the grade of tumor and the expression of CD44 (P = 0.014). The survival analysis showed a poor prognosis of patients with CD44-positive tumors (P = 0.008); and this was more prominent in the intestinal (P = 0.001) rather than diffuse type. CONCLUSION: Cell adhesion molecule CD44 is highly expressed in gastric adenocarcinoma. CD44 expression is correlated with a poor prognosis in patients with the intestinal type of gastric adenocarcinoma. CD44 can, therefore, be utilized as a prognostic marker for this group of patients. | Kamran Ghaffarzadehgan Mostafa Jafarzadeh Hamid Reza Raziee Hamid Reza Sima Ehsan Esmaili-Shandiz Hanieh Hosseinnezhad Ali Taghizadeh Kermani Omeed Moaven Maryam Bahrani | 2008 | World Journal of Gastroenterology2008，14，41： | 18 |
| 2 | Hot deformation behavior of microstructural constituents in a duplex stainless steel during high-temperature straining显示文摘The hot deformation characteristics of 1.4462 duplex stainless steel(DSS)were analyzed by considering strain partitioning between austenite and ferrite constituents.The individual behavior of ferrite and austenite in microstructure was studied in an iso-stress condition.Hot compression tests were performed at temperatures of 800-1100 C and strain rates of 0.001-1 s 1.The flow stress was modeled by a hyperbolic sine constitutive equation,the corresponding constants and apparent activation energies were determined for the studied alloys.The constitutive equation and law of mixture were used to measure the contribution factor of each phase at any given strain.It is found that the contribution factor of ferrite exponentially declines as the Zener-Hollomon parameter(Z)increases.On the contrary,the austenite contribution polynomially increases with the increase of Z.At low Z values below 2.6.×1015(lnZ=35.5),a negative contribution factor is determined for austenite that is attributed to dynamic recrystallization.At high Z values,the contribution factor of austenite is about two orders of magnitude greater than that of ferrite,and therefore,austenite can accommodate more strain.Microstructural characterization via electron back-scattered difraction(EBSD)confirms the mechanical results and shows that austenite recrystallization is possible only at high temperature and low strain rate. | Amir Momeni Shahab Kazemi Ali Bahrani | 2013 | International Journal of Minerals,Metallurgy and Materials2013，20，10： | 11 |
| 3 | Explicit reinforcement models for fully-grouted rebar rock bolts显示文摘This paper investigates the explicit use of rock reinforcement in a discontinuous stress analysis model.A series of numerical experiments was undertaken to evaluate the performance of local and global reinforcement models implemented in universal distinct element code(UDEC).This was made possible by calibrating the reinforcement models to the laboratory behavior of a fully-grouted rebar bolt tested under pure pull and pure shear loading conditions.The model calibration focuses on matching different loading stages of the force-displacement curve including the initial elastic response,the hardening behavior and the bolt rupture.The paper concludes with a discussion on the suitability of the different reinforcement models in UDEC including their advantages and limitations.Finally,it addresses the choice of input parameters required for a realistic simulation of fully-grouted rebar bolts. | Navid Bahrani John Hadjigeorgiou | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，2： | 10 |
