To examine the expression status of TSP50 in different types of human tumors. we tested the expression of TSP50 in Lung cancer, stomach cancer, liver cancer, colon cancer and prostate cancer by performing IHC assays technique. the expression of TSP50 in Lung cancer indicated that the positive rate was about 89%; the expression of TSP50 in stomach cancer the positive rate was about 88%; the expression...
In this paper 2D Otsu algorithm based on particle swarm optimization (PSO) is proposed to segment CT lung images. This method can extract pulmonary parenchyma from multisliced CT images, which is primary step to detect the pulmonary disease such as lung cancer, tumor, and mass cells. In the automated pulmonary disease diagnosis, image segmentation plays an important role and image analysis result...
Positron emission tomography - computed tomography (PETCT) is now accepted as the best imaging technique to accurately stage lung cancer. The consistent and accurate interpretation of PET-CT images, however, is not a trivial task. We propose a content-based image retrieval system for retrieving similar cases from an imaging database as a reference dataset to aid the physicians in PET-CT scan interpretation...
Genome-wide DNA methylation was analysed in tumor and normal tissues. HOXA9, HOXD4, TBX4 were found to be hypermethylated in tumor tissues whereas PAX4 was found to be hypermethylated in normal tissues. HOXD4 and TBX4 are suggested to be potent tumor suppressor genes or tumor suppressor associated genes.
Respiratory gated radiotherapy for lung cancer allows for more precise delivery of prescribed radiation dose to the tumor, while minimizing normal tissue complications. Techniques for fluoroscopic gating without implanted fiducial markers have been developed in a classification framework. Due to the high-dimensionality nature of the images, dimensionality reduction techniques such as principal component...
Gene expression data usually contains a large number of genes (several thousand or more) but a small number of samples (usually <100). Among all the genes, many are irrelevant, insignificant or redundant to the discriminant problem under investigation. Hence the identification of informative genes, which have the greatest power for classification, is of fundamental and practical importance to the...
Positron Emission Tomography is a state of art functional imaging technique used in accurate detection of cancer. Regions of interest including tumor in the thoracic region face a unique problem of movement due to the involuntary motion of the organs. To avoid irradiation of healthy tissues during radiotherapy treatment planning, accurate tracking of the moving parts during different stages of cardiac...
