Automatic identification of abnormal cervical cells, including feature representation, feature combination and classification strategy, is highly demanded in women's annual cervical cancer screenings. However, previous methods only deal with one or two of these three phases, and currently there is few complete framework for this problem. A novel three-phrase boosting framework is proposed for the...
Aqueous extraction and alkaline (NaOH) hydrolysis method were comparatively studied in polysaccharides extraction from submerged-cultured Agaricus blazei mycelia. The results show that the polysaccharide content and the total extract rate from alkaline extraction method were obviously higher than those from the aqueous extraction method. Optimization results by the orthogonal matrix method on polysaccharide...
To screen potential oleaginous microorganisms for production of microbial lipid, thirty-one yeast strains from forest soils collected from Hunan Province, China, were tested for their potentiality to produce microbial lipid, and fourteen potential strains were further screened. The results showed that yeast strain SCIM 2.012 displayed the most potential ability in producing microbial lipid, the lipid...
Through the evaluation of the 31Phosphorus Magnetic Resonance Spectroscopy (31P-MRS), we can distinguish three types of diagnosis: hepatocellular carcinoma, normal and cirrhosis. 71 samples of 31P-MRS data are selected including hepatocellular carcinoma, normal and cirrhosis tissue. Back-propagation neural network (BP) and Radial Basis Function Neural Network (RBF) are applied to analyze 31P-MRS data,...
In vivo 31P MRS provides non-invasive information about the chemical content of the energy metabolism in cellular level, which is important either in diagnosis or in treatment of many hepatic diseases. In this paper we applied Fisher linear discriminant analysis and quadratic discriminant analysis to classify the data samples based on 31P MRS into three types of hepatocellular carcinoma, hepatic cirrhosis...
SVM (support vector machine) is a new machine-learning technique which is developed based on statistical theory and it is applied in the various fields in recent years. We use SVM model based on 31P MRS (31Phosphorus magnetic resonance spectroscopy) data to distinguish three categories of hepatocellular carcinoma, hepatic cirrhosis and normal hepatic tissue. The recognition accuracy of the three categories...
Water and chloroform extracts of various Chinese medicinal insects were added into the medium of Ganodermasinense to investigate the effects of the extracts on production of biomass, intracellular polysaccharides (IPS), and extracellular polysaccharides (EPS). The results showed that chloroform extract of E. sinensis (CES) at 55 mg/L lead to significant increase in both biomass and IPS concentration...
To screen stimulators for mycelial growth and polysaccharides production of Ganodermalucidum, the fungus was inoculated into the media with and without supplementation of several fatty acids and ether extracts of Chinese medicinal insects. Palmitic acid at 1.0 g/L lead to significant increase in both biomass and extracellular polysaccharides (EPS) concentration from 7.73 plusmn 0.41 to 10.21 plusmn...
Buckwheat (Fagopyrum esculentum Moench) cultivars differred in aluminum (Al) resistance were selected to investigate the possible role of cell wall pectin content and its binding capacity to Al in Al resistance. Al contents in root apices of Al-resistant cultivars were lower than those in Al-sensitive cultivars, suggesting the Al exclusion mechanism was acting in Al-resistant buckwheat cultivars....
This paper is aimed to select PD gene based on microarray dataset from multiplex 3D brain gene expression mapping. Firstly, we used a statistical method for the normalization of genes. Secondly, we described a strategy to select PD gene. Dividing data into two subsets, calculating the standard deviation (SD) of gene expression and using order statistics and binomial distribution, we chose among the...
