The prognostic role of survivin expression in breast cancer patients has been widely reported. However, controversy still remains. Thus, a meta-analysis was conducted to obtain a more precise estimation of the relationship between survivin expression and overall survival (OS) in breast cancer patients. Relevant articles were selected for further assessment(More)
Cyclooxygenase-2 (COX-2) is believed to be involved in gastric carcinogenesis. However, it is still controversial whether COX-2 expression can be regarded as a prognostic factor for gastric cancer patients. To obtain a more accurate relationship between COX-2 overexpression and prognosis in gastric cancer by meta-analysis. Relevant articles published up to(More)
AIM To compare the prevalence and diversity of gastrointestinal (GI) symptoms in patients undergoing peritoneal dialysis (PD) and hemodialysis (HD). METHODS Two hundred and ninety-four end-stage renal disease patients participated in the study, including 182 HD and 112 PD patients. Dimension scores were calculated from a modified gastrointestinal symptom(More)
There is evidence pointing to a possible role of diet on cancer etiology. Prior studies evaluating the relationship between fish consumption and lung cancer risk reported inconclusive results. The aim of this study was to achieve a comprehensive assessment of the relationship between fish consumption and lung cancer risk through systematic review and(More)
BACKGROUND Matrix metalloproteinase 9 (MMP-9) is related to tumor invasion and metastasis. However, the role of MMP-9 expression in breast cancer survival remains controversial. The purpose of this study was to accomplish a more accurate estimation of the association between MMP-9 expression and survival results in breast cancer patients through(More)
Using a unique dataset on students from the first regional schools in colonial Benin, we investigate the effect of education on living standards, occupation and political participation. Since both school locations and student cohorts were selected with very little information, treatment and control groups are balanced on observables. We can therefore(More)
A substantial body of research in political science finds that refugees increase the likelihood of conflict within the states that host them. This literature concludes that refugees do so by exacerbating ethnic tensions, intensifying economic competition, and expanding insurgent networks. Related research finds that refugees diffuse regional civil wars.(More)
Two purely inorganic three-dimensional (3D) frameworks [Mn4(H2O)11V(IV)(18)O42(PO4)](7-) (1) and [Mn2(H2O)7V(IV)(18)O42(PO4)](11-) (2) were synthesized under hydrothermal conditions and fully characterized by single-crystal X-ray structural analysis, IR spectroscopy, thermogravimetric analysis and PXRD. Structural analysis revealed that these two compounds(More)
