As a useful data mining technique biclustering identifies local patterns from gene expression data. A bicluster of a gene expression dataset is a subset of genes which exhibit similar expression patterns along a subset of conditions. In this paper a new method is introduced based on greedy search algorithm combined with the evolutionary technique particle(More)
BACKGROUND Type 2 diabetes mellitus (T2DM) is a serious threat to human health and remains incurable. Insulin deficiency seems to be attributed to the progressive failure of pancreatic islet β-cells and immune cells such as T cells mediated cytotoxicity may be involved in the loss of pancreatic islet β-cells in T2DM. Targeting on the immune system to(More)
A convenient and effective strategy for preparation nanohybrid film of multi-wall carbon nanotubes (MWNT) and gold colloidal nanoparticles (GNPs) by using proteins as linker is proposed. In such a strategy, hemoglobin (Hb) was selected as model protein to fabricate third-generation H2O2 biosensor based on MWNT and GNPs. Acid-pretreated, negatively charged(More)
A dispersible graphene/multiwall carbon nanotube/gold nanocluster (GP/MWCNTs/AuNCs) hybrid in aqueous solution was prepared in situ, and characterized by transmission electron microscopy (TEM) and ultraviolet-visible (UV-vis) spectroscopy. Based on the fact that phenolic compounds can enhance the electrogenerated chemiluminescence (ECL) signal at the(More)
A simple and effective strategy for fabrication of hydrogen peroxide (H2O2) biosensor has been developed by entrapping horseradish peroxidase (HRP) in chitosan/silica sol-gel hybrid membranes (CSHMs) doped with potassium ferricyanide (K3Fe(CN)6) and gold nanoparticles (GNPs) on platinum electrode surface. The hybrid membranes are prepared by cross-linking(More)
A novel scheme for the fabrication of gold/platinum hybrid functionalized ZnO nanorods (Pt-Au@ZnONRs) and multiwalled carbon nanotubes (MWCNTs) modified electrode is presented and its application for cholesterol biosensor is investigated. Firstly, Pt-Au@ZnONRs was prepared by the method of chemical synthesis. Then, the Pt-Au@ZnONRs suspension was dropped on(More)
In this paper, the reduced graphene oxide and multiwall carbon nanotubes hybrid materials (RGO-MWNTs) were prepared and a strategy for detecting environmental contaminations was proposed on the basis of RGO-MWNTs modified electrode. The hybrid materials were characterized by the scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray(More)
A novel electrode was developed through electrodepositing gold nanoparticles (GNPs) on overoxidized-polyimidazole (PImox) film modified glassy carbon electrode (GCE). The combination of GNPs and the PImox film endowed the GNPs/PImox/GCE with good biological compatibility, high selectivity and sensitivity and excellent electrochemical catalytic activities(More)
OBJECTIVE • To investigate the feasibility of tissue-engineered corpus cavernosum (TECC) with muscle-derived stem cells (MDSCs) as seed cells and determine the growth potential in vivo. MATERIALS AND METHODS • Acellular corporal collagen matrices (ACCMs) were obtained from adult rabbit penis by a cell removal procedure. MDSCs were separated and purified(More)
