AIM To investigate the anatomic variations in the cystic artery by laparoscopy, and to provide a new classification system for the guidance of laparoscopic surgeons. METHODS Six hundred patients treated with laparoscopic cholecystectomy from June 2005 to May 2006 were studied retrospectively. The laparoscope of 30(o)(Stryker, American) was applied.(More)
Hepatitis B virus (HBV) causes acute and chronic hepatitis and hepatocellular carcinoma. Small interfering RNA (siRNA) and lamivudine have been shown to have anti-HBV effects through different mechanisms. However, assessment of the genome-wide effects of siRNA and lamivudine on HBV-producing cell lines has not been reported, which may provide a clue to(More)
PURPOSE Compare dual-time-point and single-time 18F-FDG PET in the evaluation of locoregional lymph node metastases in patients with esophageal squamous cell cancer. Then assess the efficacy of dual-time-point PET in the diagnosis of such nodules. METHODS 34 patients with thoracic esophageal squamous cell cancer underwent dual-time-point PET before(More)
Polyploidization is known to accompany altered DNA methylation in higher plants, which plays an important role in gene expression regulation and maintaining genome stability. While the characteristics of DNA methylation in different polyploid plants are still to be elucidated; here, status of genomic DNA methylation in a series of diploid, triploid, and(More)
A novel image watermarking method in multiwavelet domain based on support vector machines (SVMs) is proposed in this paper. The special frequency band and property of image in multiwavelet domain are employed for the watermarking algorithm. After performed single-level multiwavelet decomposition on each image block of an image, a mean value modulation(More)
A change of oil/water interfacial tension in the presence of cationic or anionic surfactants in an organic phase was observed due to the addition of charged fine solids in the aqueous phase. The charged fine solids in the aqueous phase adsorb surfactants diffused from the oil phase, thereby causing an increase in the bulk equilibrium surfactant(More)
3D-TV is well expected as next advancement in television. The conversion technique of two-dimensional (2D) images to 3D images is an effective way to alleviate the shortage of 3D contents. The most important and difficult problem in 2D-to-3D conversion is how to generate or estimate depth information using only a single-view image. In this paper, a new(More)
A new fingerprint matching algorithm using the elaborate combination of minutiae and curvature maps from fingerprint images is proposed in this paper. First of all, we propose a simple method for curvature calculation based on fingerprint orientation fields from fingerprint images. Secondly, a curvature-based minutia specifier, which appears to be a(More)
Many flavonoids extracted from nature plants have been reported to exert antidepressant-like effect in animal studies. The present study was designed to observe the effects of liquiritin, a flavone compound derived from Glycyrrhiza uralensis, on the behaviors of chronic variable stress induced depression model rats and to explore the possible association(More)
