The objective is to evaluate the association of periodontal disease with the risk of oral cancer. Literature retrieval, selection and assessment, data extraction, and meta-analyses were performed according to the RevMan 5.0 guidelines. In the meta-analysis, we utilized random-effect model to pool the odds ratio (OR) according to the test of heterogeneity. A… (More)
This paper proposes a novel method of key-frame extraction for use with motion capture data. This method is based on an unsupervised cluster algorithm. First, the motion sequence is clustered into two classes by the similarity distance of the adjacent frames so that the thresholds needed in the next step can be determined adaptively. Second, a dynamic… (More)
OBJECTIVE The objective of this study is to compare the biomechanical properties and clinical outcomes of Tile B1 type pubic symphysis diastasis (PSD) treated by percutaneous cannulated screw fixation (PCSF) and reconstruction plate screw fixation (RPSF). MATERIALS AND METHODS Finite element analysis (FEA) was used to compare the biomechanical properties… (More)
Five new hybrid monoterpenoid indole alkaloids bearing an unusual 2,2-dimethyl-4-oxopiperidin-6-yl moiety, namely rauvotetraphyllines F–H (1, 3, 4), 17-epi-rauvotetraphylline F (2) and 21-epi-rauvotetraphylline H (5), were isolated from the aerial parts of Rauvolfia tetraphylla. Their structures were established by extensive spectroscopic analysis. The new… (More)
Transforming acidic coiled-coil protein 3 (TACC3) is essential for cell mitosis and transcriptional functions. In the present study, we first demonstrated that both TACC3 protein and mRNA levels were elevated in HCC tissue samples compared with non-cancerous tissue biopsies according to western blot analyses, immunohistochemistry (IHC) and quantitative… (More)
Five new indole alkaloids rauvotetraphyllines A–E (1–5), together with eight known analogues, were isolated from the aerial parts of Rauvolfia tetraphylla. The structures were established by means of spectroscopic methods.
One rare tetracyclic macroline-type indole alkaloid, named rauvoyunine A (1), and two new picraline-type alkaloids rauvoyunines B and C (2 and 3) were isolated from the aerial parts of Rauvolfia yunnanensis. Their structures were elucidated on the basis of extensive spectroscopic analysis. Compounds 2 and 3 were evaluated for their in vitro cytotoxicity… (More)
