For the first time, highly c-axis oriented heteroepitaxial AlN thin films have been successfully grown on epitaxial 3C-SiC films on Si (100) substrates. The AlN films deposited by the AC reactive magnetron sputtering at temperatures of approximately 300-450 °C were characterized using the scanning electron microscope (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and transmissio...

Using an assay capable of detecting sequence-specific RNA/protein interactions in mammalian cells, we demonstrate that the poliovirus and rhinovirus 3C proteinases are able to bind structured target RNA sequences derived from their respective 5' noncoding regions in vivo. Specific RNA binding by poliovirus 3C was found to be dependent on the integrity of stem-loop d of the RNA cloverleaf struct...

Identification of novel cellular proteins as substrates to viral proteases would provide a new insight into the mechanism of cell-virus interplay. Eight nuclear proteins as potential targets for enterovirus 71 (EV71) 3C protease (3C(pro)) cleavages were identified by 2D electrophoresis and MALDI-TOF analysis. Of these proteins, CstF-64, which is a critical factor for 3' pre-mRNA processing in a...

We propose a new cryptographic construction called 3C, which works as a pseudorandom function (PRF), message authentication code (MAC) and cryptographic hash function. The 3Cconstruction is obtained by modifying the Merkle-Damg̊ard iterated construction used to construct iterated hash functions. We assume that the compression functions of Merkle-Damg̊ard iterated construction realize a family of ...

UNLABELLED Enterovirus 71 (EV71) causes hand, foot, and mouth disease in young children and infants. Severe infection with EV71 can lead to various neurological complications or fatal diseases. However, the mechanism of EV71 pathogenesis is poorly understood. Emerging evidence suggests that EV71 modulates type I interferon (IFN) and cytokine responses. Here, we show that EV71 disables component...

BACKGROUND Osteoarthritis (OA) is a chronic joints disease characterized by progressive degeneration of articular cartilage due to the loss of cartilage matrix. Previously, we found, for the first time, that an acidic glycan from Angelica Sinensis Polysaccharides (APSs), namely the APS-3c, could protect rat cartilage from OA due to promoting glycosaminoglycan (GAG) synthesis in chondrocytes. In...

Let £ be a split semisimple Lie algebra over a field of characteristic zero and <£ = 3C+ ]C«eA«£a be the rootspace decomposition of <£ relative to a splitting Cartan subalgebra 5C, where the subset A of 3C* is the corresponding root-system. Fix a simple system of roots {c*i, «2, • • • , ai}, for which the positive (resp. negative) roots are denoted by A+ (resp. A_). For a EA let Ra be the W...

Phenylalanine ammonia-lyase (PAL) and peroxidase (POD) enzyme activities, total phenolics and pyruvic acid (PA) (as pungency indicator) were measured in onion bulb tissues (c.v. Rouge Amposta) during storage at 4 and 20 3C. After 2 wk, PAL activity increased at 4 3C, but decreased at 20 3C, and after 4 wk, PAL activity at 20 3C was higher than activity observed at 4 3C. Peroxidase activity was ...

Two leukemogenic viral populations were derived from a radiation leukemia virus of the C57BL mouse. One (FB), in which only B-tropic virus could be detected, was obtained in vivo by serial passage of cell-free extract in newborn rats. The second (3C), a complex containing at least B-tropic and xenotropic viruses, was produced in vitro by a permanent cell line (13-3C) established from the spleen...

The nanocrystal 3C-SiC/ZrO₂ bilayer films that could be used as the protective coatings of zirconium alloy fuel cladding were prepared on a single-crystal Si substrate. The corresponding nanocrystal 3C-SiC film and nanocrystal ZrO₂ film were also dividedly synthesized. The microstructure of nanocrystal films was analyzed by grazing incidence X-ray diffraction (GIXRD) and cross-sectional transmi...
