the main objective in classification of the nmr spectra of cancerous and healthy tissue , with high number of features is the prerequisites of the minimum number of samples. therefore the use of conventional classifier on this type of the data is not recommended. in the current work, different structures of the artificial neural networks (ann) were tried on classification of different cancerous...
Although a splicing variant of prostate specific antigen (PSA-v) mRNA has been described previously, whether its protein (PSA-v or PSA-related protein 1, i.e., PSA-RP1) is actually expressed in human prostate cells remains elusive. We report that PSA-v protein is expressed in prostatic epithelia of both cancerous and benign tissues. Also, secreted PSA-v can be detected in the medium of a prosta...
Traditional breast cancer imaging methods using microwave Nearfield Radar Imaging (NRI) seek to recover the complex permittivity of the tissues at each voxel in the imaging region. This approach is suboptimal, in that it does not directly consider the permittivity values that healthy and cancerous breast tissues typically have. In this paper, we describe a novel unmixing algorithm for detecting...
Surfactant proteins play important roles in lung surfactant function and innate immunity. The DNA methylation state of 11 CpG sites of surfactant protein (SP)-A1, -B, -C, and -D was determined using universal bead arrays. A total of 90 cancerous and non-cancerous tissues from 23 patients with adenocarcinoma and 22 with squamous cell carcinoma were studied. These were divided into a training set...
The dysbiosis of the human intestinal microbiota is linked to sporadic colorectal carcinoma (CRC). The present study was designed to investigate the gut microbiota distribution features in CRC patients. We performed pyrosequencing based analysis of the 16S rRNA gene V3 region to investigate microbiota of the cancerous tissue and adjacent non-cancerous normal tissue in proximal and distal CRC sa...
Breast cancer tissues have been analyzed to determine the feasibility of the chemical changes taking place in the biological tissue, which can be identified and categorized into various grades. FTIR spectroscopy can be used for qualitative analysis of cancerous breast tissues because of its sensitivity to the changes in the biomolecules in the tissues. IR spectra was taken for a total number of...
