BACKGROUND Since there is high local failure and poor survival for unresectable esophageal squamous cell carcinoma (ESCC), the necessity of elective node irradiation is controversial. The purpose of this study was to investigate the failure patterns and survival in patients with locally advanced ESCC receiving involved-field irradiation (IFI). METHODS A(More)
PURPOSE Not only is the expression of CXCR4 on breast cancers a key determinant of tumor metastasis, CXCL12 exhibiting peak levels of constitutive expression in organs representing the first destinations of cancer metastasis, but is proposed to be also essential for the organ-specific metastatic process. METHODS In this study, the expressions of CXCR4 and(More)
In this paper we are concerned with the inverse spectral problems for energy-dependent Sturm-Liouville problems (that is, differential pencils) defined on interval [0, 1] with two potentials known on a subinterval [a 1 , a 2 ] ⊂ [0, 1]. We prove that the potentials on the entire interval [0, 1] and the boundary condition at x = 1 are uniquely determined in(More)
a r t i c l e i n f o a b s t r a c t Keywords: Eigenvalue Indefinite Sturm–Liouville problem Inverse spectral problem We prove that the potential q(x) of an indefinite Sturm–Liouville problem on the closed interval [a, b] with the indefinite weight function w(x) can be determined uniquely by three spectra, which are generated by the indefinite problem(More)
