We used CDK4/hTERT-immortalized normal human bronchial epithelial cells (HBEC) from several individuals to study lung cancer pathogenesis by introducing combinations of common lung cancer oncogenic changes (p53, KRAS, and MYC) and followed the stepwise transformation of HBECs to full malignancy. This model showed that: (i) the combination of five genetic(More)
Two new gallotannins, pistafolins A (1) and B (2), were isolated from the leaf extract of Pistacia weinmannifolia. Their structures were determined by spectral methods. Four known gallotannins (3-6), seven known flavonoid glycosides (7-13), along with 1-O-beta-D-(6'-O-galloyl)-glucopyranosyl-3-methoxy-5-hydroxybenzen e (14), gallic acid (15), methyl gallate(More)
We propose a novel capacity model for complex networks against cascading failure. In this model, vertices with both higher loads and larger degrees should be paid more extra capacities, i.e. the allocation of extra capacity on vertex i will be proportional to k γ i , where ki is the degree of vertex i and γ > 0 is a free parameter. We have applied this(More)
A new cyclopeptide, grifficyclocin A (1), and a new aporphine alkaloid, griffinin (2) were isolated together with two known styryllactones from the stems of Goniothalamus griffithii. Their structures were identified spectroscopically and chemically. Among them, the griffinin (2) was isolated as the enol form in two tautomers, and the two known(More)
We aimed to analyze the clinical and radiographic efficacy of a new zero-profile anchored spacer called the ROI-C in anterior discectomy and fusion (ACDF) for multilevel cervical spondylotic myelopathy (MCSM). We retrospectively reviewed the clinical, radiological outcomes and complications of multilevel ACDF with the ROI-C or with the polyetheretherketone(More)
