The electronic properties of zincblende ZnSe/Si core-shell nanowires (NWs) with a diameter of 1.1-2.8 nm are calculated by means of the first principle calculation. Band gaps of both ZnSe-core/Si-shell and Si-core/ZnSe-shell NWs are much smaller than those of pure ZnSe or Si NWs. Band alignment analysis reveals that the small band gaps of ZnSe/Si core-shell NWs are caused by the interface state...

A survey of broadband Co2+and Cr2+-based lasers is presented. These mid-IR sources, operating in the very interesting “molecular fingerprint” region between ∼1.6 and 3.5μm offer the broadest bandwidth from all solid-state vibronic lasers. The emphasize is made on Cr2+-doped lasers, which have not only the widest and the highest gain, but also operate at room-temperature and produce the shortest...

Systemic lupus erythematosus is an autoimmune disease characterized by autoantibody production against nuclear Ags. Recent studies suggest that the Cr2 gene, which encodes for complement receptor (CR)1 and CR2, is important in disease susceptibility. Because the precise disease phenotype related to this gene, in isolation or in relation to other genetic loci, is not known, we analyzed C57BL/6 m...

PURPOSE Polymorphisms in factor H (fH), an inhibitor of the alternative pathway (AP) of complement activation, are associated with increased risk for age-related macular degeneration (AMD). The authors investigated the therapeutic use of a novel recombinant form of fH, CR2-fH, which is targeted to sites of complement activation, in mouse choroidal neovascularization (CNV). CR2-fH consists of th...

Shell-core structure of ZnSe nano crystalline cluster is used for marking glucose molecules in this paper. Fluorescent detection is successfully realized in microchannels. Mercaptoacetic acid is used for packing ZnSe nano crystalline cluster, which is dissolved in the water. Carboxyl of mercaptoacetic is used for connecting glucose molecule, and mixture solution of glucose molecule marked with ...

The major murine systemic lupus erythematosus (SLE) susceptibility locus, Sle1, corresponds to three loci independently affecting loss of tolerance to chromatin in the NZM2410 mouse. The congenic interval corresponding to Sle1c contains Cr2, which encodes complement receptors 1 and 2 (CR1/CR2, CD35/CD21). NZM2410/NZW Cr2 exhibits a single nucleotide polymorphism that introduces a novel glycosyl...

Collagen-induced arthritis (CIA) represents an animal model of autoimmune polyarthritis with similarities to human rheumatoid arthritis, and therapy with various systemic complement-inhibitory proteins has been investigated in this model with varying results. We investigated the use of complement receptor 2 (CR2)-Crry, a complement inhibitor with the ability to target C3 breakdown products depo...

A novel one-step cation exchange approach has been developed to prepare ZnO-decorated ZnSe nanorods (ZnSe-ZnO NRs), a prototype type-II semiconductor nanoheterostructure. Because of the staggered band offset which promoted effective charge separation, the as-synthesized ZnSe-ZnO NRs exhibited remarkable photocatalytic activities under visible light illumination, demonstrating their promising po...

Evidence for electron accumulation in the ZnSe side of n-ZnSe/n-GaAs heterostructures is presented. An n-GaAs buffer layer, approximately 1 pm thick, grown with low 1015 electronic concentration on a semi-insulating (100) GaAs substrate is fully depleted of electrons when an additional epilayer of nZnSe is grown on top of it. The n-GaAs epilayer electron concentration is restored when the ZnSe ...

Human complement receptor type 2 (CR2) is the B lymphocyte receptor for C3d and the Epstein-Barr virus. This protein is also a member of a family of C3b/C4b binding proteins that regulate complement activation, comprise tandemly repeated 60-75 amino acid sequences, and whose genes map to band q32 on chromosome 1. Overlapping cDNA clones encoding the entire human CR2 protein have been isolated f...
