Recently, there has been much progress in algorithm development for image reconstruction in cone-beam computed tomography (CT). Current algorithms, including the chord-based algorithms, now accept minimal data sets for obtaining images on volume regions-of-interest (ROIs) thereby potentially allowing for reduction of X-ray dose in diagnostic CT. As these(More)
Reflectivity tomography is an imaging technique that seeks to reconstruct certain acoustic properties of a weakly scattering object. Besides being applicable to pure ultrasound imaging techniques, the reconstruction theory of reflectivity tomography is also pertinent to hybrid imaging techniques such as thermoacoustic tomography. In this work, assuming(More)
MicroRNA-30c (miR-30c) acts as a tumor suppressor or a tumor promoter in various human malignancies. However, the involvement of miR-30c in prostate cancer (PCa) is still unclear. The aim of this study was to investigate the molecular function and the clinical significance of miR-30c in PCa. Expression levels of miR-30c in PCa tissues and cells were(More)
Micro-CT with a high spatial resolution in combination with computer-based-reconstruction techniques is considered a powerful tool for morphological study of insects. The quality of CT images crucially depends on the precise knowledge of the scan geometry of the micro-CT system. In this paper, we have proposed a method to calculate the deviation of rotating(More)
BACKGROUND Cystic renal cell carcinoma (CRCC) is relatively rare; CRCC is frequently misdiagnosed as a benign renal cyst. CRCC carries an excellent prognosis following surgical treatment. The aim of our study was to summarize the management of CRCC and to characterize the prognosis of affected patients. METHODS A retrospective study of 67 patients with(More)
A successful example of self-assembly in a biological system is that DNA can be an excellent agent to self-assemble into desirable two and three-dimensional nanostructures in a well-ordered manner by specific hydrogen bonding interactions between the DNA bases. The self-assembly of DNA bases have played a significant role in constructing the hierarchical(More)
BACKGROUND Recently, Mycobacterial Interspersed Repetitive Unit (MIRU) was supposed to be associated with drug resistance in Mycobacterium tuberculosis (M. tuberculosis), but whether the association exists actually in local strains in China was still unknown. This research was conducted to explore that association and the predictability of MIRU to drug(More)
BACKGROUND The diagnosis of pulmonary tuberculosis (PTB) is complicated and time-consuming currently. There was association of PTB with serum tumor markers. In this study we aimed to evaluate the predictive role of serum CA125, CA199 and CEA as diagnostic tools for PTB. METHODS This study was designed as a case-control study with 565 subjects who visited(More)
