Mutations of the TMPRSS6 gene are considered the major genetic factors for iron-refractory iron deficiency anemia (IRIDA). Artificial clone libraries containing 17 known mutations of the TMPRSS6 gene were used to develop a high-resolution melting (HRM) assay for the detection of 17 TMPRSS6 gene mutations. The melting temperatures and melting curves were(More)
Increasing evidence indicates that copy number variants (CNVs) have great relevance to common human diseases. In α-thalassemia, clinical phenotypes are related to genotypes, specifically copy number changes in the human α-globin gene cluster. Assays are available for high-throughput screening of unknown CNVs genome-wide and also for targeted CNV genotyping(More)
Genotyping of single nucleotide polymorphisms (SNPs) is a central challenge in disease diagnostics and personalized medicine. A novel label-free homogeneous SNP genotyping technique is developed on the basis of ligation-mediated strand displacement amplification (SDA) with DNAzyme-based chemiluminescence detection. Discrimination of single-base mismatches(More)
Maternal blood was obtained from 18 pregnant women at 7 to 25 weeks of gestation. After Percoll discontinuous density gradient centifugation, the fetal nucleated red blood cells (NRBCs) were stained with Kleihauer test. Positive fetal cells appeared with an intense red cytoplasmic staining while maternal cells with adult haemoglobin were colourless.(More)
OBJECTIVE To investigate the feasibility of multiple displacement amplification (MDA) to apply in the non-invasive prenatal genetic diagnosis of Duchenne muscular dystrophy (DMD). METHODS Maternal blood was obtained from 20 pregnant women at 7 to 25 weeks of gestation. After the discontinuous density gradient centrifugation with Percoll, the fetal(More)
In the present study, an innovative method is proposed, employing both wavelet transform and neural network, to analyze the near-infrared spectrum data in oil shale survey. The method entails using db8 wavelet at 3 levels decomposition to process raw data, using the transformed data as the input matrix, and creating the model through neural network. To(More)
