The important issue of mechanical assemblies has been a subject of intense research over the past several years. Most electromechanical products are assemblies of several components, for various technical as well as economic reasons. This report provides an object-oriented definition of an assembly model called the Open Assembly Model (OAM) and defines an(More)
Cell-penetrating peptides can carry a variety of biologically active molecules into cells. Here we have identified a novel CPP derived from the C-terminus of human extracellular superoxide dismutase (hC-SOD3) which was shown to be located throughout in the cytoplasm and nucleus by fluorescence microscopy investigation. Furthermore, when apoptin fused to(More)
Rice blast is one of the most destructive diseases affecting rice worldwide. The adoption of host resistance has proven to be the most economical and effective approach to control rice blast. In recent years, sequence-specific nucleases (SSNs) have been demonstrated to be powerful tools for the improvement of crops via gene-specific genome editing, and(More)
BACKGROUND Ketamine, a noncompetitive N-methyl-D-aspartate receptor antagonist, is widely used as an intravenous anesthetic agent and has also been shown to possess anti-inflammatory effects, but its effects on high-mobility group box-1 (HMGB1) have not been well defined. In the present study, we investigated the effects of ketamine on HMGB1 in(More)
OBJECTIVE To evaluate collagen(Col)-hyaluronan (HA)-chondroitin sulfate (CS) tri-copolymer as a new biomimetic biodegradable polymer scaffold for application of the articular cartilage tissue engineering. METHODS The Col-HA-CS tri-copolymer was prepared by freezing and lyophilization and was cross-linked by 1-ethyl-3-(3-dimethy inaminoproyl) carbodiimide(More)
MAP30 (Momordica Antiviral Protein 30 Kd), a single-stranded type-I ribosome inactivating protein, possesses versatile biological activities including anti-tumor abilities. However, the low efficiency penetrating into tumor cells hampers the tumoricidal effect of MAP30. This paper describes MAP30 fused with a human-derived cell penetrating peptide HBD which(More)
In this study, highly porous collagen-HA scaffolds were prepared by solid-liquid phase separation method. Microstructure of the composites was characterized by SEM, TEM and XRD. The results show that collagen-HA scaffolds are porous with three-dimension interconnected fiber microstructure, pore sizes are 50-150 microm, and HA particles are dispersed evenly(More)
A novel lipase gene from Aspergillus fumigatus, afl1-1, was cloned and expressed with a molecular mass of 38 kDa in Escherichia coli for the first time. The recombinant lipase had a preference for short carbon chain p-nitrophenyl esters, especially toward C2 p-nitrophenyl ester and exhibited potent hydrolysis activity that had not been observed. The optimum(More)
A strategy successfully used by manufacturing companies is to develop product families so as to offer a variety of products with reduced development costs. This paper introduces our initial research on the representation of the evolution of product families and of the rationale of the changes involved. The information model representing product families is(More)
A nucleic acid sequence MC, encoding Momordica Chanrantia anti-hyperglycaemic peptide MC6 (accession: AAX06814) synthesized according to Escherichia coli preferred codons, was cloned and expressed in E. coli. Recombinant protein pQE8-MC (about 3.5 kDa) was purified and analyzed by 20% SDS–PAGE and western blot. It revealed that the expressed pQE8-MC had(More)
