Lychee-like TiO@FeO Core-Shell Nanostructures with Improved Lithium Storage Properties as Anode Materials for Lithium-Ion Batteries.

In this study, lychee-like TiO@FeO microspheres with a core-shell structure have been prepared by coating FeO on the surface of TiO mesoporous microspheres using the homogeneous precipitation method. The structural and micromorphological characterization of TiO@FeO microspheres has been carried out using XRD, FE-SEM, and Raman, and the results show that hematite FeO particles (7.05% of the total mass) are uniformly coated on the surface of anatase TiO microspheres, and the specific surface area of this material is 14.

Structural and Electrochemical Properties of LiO-VO-BO-BiO Glass and Glass-Ceramic Cathodes for Lithium-Ion Batteries.

In this study, 20LiO-60VO-(20 - )BO-BiO ( = 5, 7.5, 10 mol%) glass materials have been prepared by the melt-quenching method, and the structure and morphology of the glass materials have been characterized by XRD, FTIR, Raman, and FE-SEM. The results show that the disordered network of the glass is mainly composed of structural motifs, such as VO, BO, BiO and BiO.

Whole Genome Analysis of Two Novel Type 2 Porcine Reproductive and Respiratory Syndrome Viruses with Complex Genome Recombination between Lineage 8, 3, and 1 Strains Identified in Southwestern China.

Recombination among porcine reproductive and respiratory syndrome viruses (PRRSVs) is thought to contribute to the emergence of new PRRSV variants. In this study, two newly emerged PRRSV strains, designated SCcd16 and SCya17, are isolated from lung tissues of piglets in Southwestern China. Genome comparative analysis reveals that SCcd16/SCya17 exhibit 93.

Assembly and immunogenicity of baculovirus-derived infectious bronchitis virus-like particles carrying membrane, envelope and the recombinant spike proteins.

Objective: To assemble infectious bronchitis virus (IBV)-like particles bearing the recombinant spike protein and investigate the humoral immune responses in chickens.

Results: IBV virus-like particles (VLPs) were generated through the co-infection with three recombinant baculoviruses separately encoding M, E or the recombinant S genes. The recombinant S protein was sufficiently flexible to retain the ability to self-assemble into VLPs.

Development of an ELISA based on a multi-fragment antigen of infectious bronchitis virus for antibodies detection.

Objectives: To develop a cost-effective ELISA for detection of antibodies against infectious bronchitis virus (IBV) by using a multi-fragment protein as coating antigen.

Results: A multi-fragment antigen, termed BE, which was composed of eight antigenic fragments selected from the three major proteins (S, M, and N) of IBV, was expressed in Escherichia coli. The entire protein had a molecular weight of 61.

Development of a multi-epitope antigen of S protein-based ELISA for antibodies detection against infectious bronchitis virus.

An indirect enzyme-linked immunosorbent assay (ELISA) method based on a novel multi-epitope antigen of S protein (SE) was developed for antibodies detection against infectious bronchitis virus (IBV). The multi-epitope antigen SE protein was designed by arranging three S gene fragments (166-247 aa, S1 gene; 501-515 aa, S1 gene; 8-30 aa, S2 gene) in tandem. It was identified to be approximately 32 kDa as a His-tagged fusion protein and can bind IBV positive serum by western blot analysis.

Lactococcus lactis anchoring avian infectious bronchitis virus multi-epitope peptide EpiC induced specific immune responses in chickens.

Mucosal immunity is critical in preventing infectious bronchitis virus (IBV) infection. To deliver viral antigens to the mucosal immune system of chickens safely and effectively, we constructed a Lactococcus lactis strain carrying IBV multi-epitope gene EpiC fused with the gene of the cell-wall anchoring domain of Staphylococcus aureus protein A. SDS-PAGE and Western blot results indicated that the fused peptide was located partially on the cell surface.
