Aplastic anemia (AA) is generally considered as an immune-mediated bone marrow failure syndrome with defective hematopoietic stem cells (HSCs) and marrow microenvironment. Previous studies have demonstrated the defective HSCs and aberrant T cellular-immunity in AA using a microarray approach. However, little is known about the overall specialty of bone(More)
When extracting discriminative features from multimodal data, current methods rarely concern themselves with the data distribution. In this paper, we present an assumption that is consistent with the viewpoint of discrimination, that is, a person's overall biometric data should be regarded as one class in the input space, and his different biometric data(More)
Although many hyperthermophilic endoglucanases have been reported from archaea and bacteria, a complete survey and classification of all sequences in these species from disparate evolutionary groups, and the relationship between their molecular structures and functions are lacking. The completion of several high-quality gene or genome sequencing projects(More)
BACKGROUND Mannan is one of the primary polysaccharides in hemicellulose and is widely distributed in plants. β-Mannosidase is an important constituent of the mannan-degrading enzyme system and it plays an important role in many industrial applications, such as food, feed and pulp/paper industries as well as the production of second generation bio-fuel.(More)
It has been investigated to conduct the surface displaying of lipase from Rhizopus oryzae onto the cells of Pichia pastoris yeast using Sed1p as an anchor protein. A yeast cell surface display plasmid pPICZαA-rol-histag-sed1p was constructed by fusing rol and sed1p gene fragments into the plasmid pPICZαA, followed by introducing recombinant plasmid into P.(More)
The aim of the present study was to investigate regulatory relationships among hypoxia-inducible factor-1α (HIF-1α), microRNA and erythroid transcription factors. K562 cells were transfected with HIF-1α knockout or with overexpression lentivirus of plasmid (MOI 10). The cells were divided into 3 groups: the negative control, overexpressing and interference(More)
