Analysis of the Genetic Diversity in Methicillin-Resistant Staphylococcus aureus Isolates from Bovine Subclinical Mastitis Case in Xinjiang, China.

Background: Diseases caused by livestock-associated methicillin-resistant Staphylococcus aureus (MRSA) are an important global public health concern, and MRSA is increasingly being isolated in bovine milk. However, information on the genotype and antimicrobial resistance of MRSA in bovine milk in Xinjiang is limited. The objective of this study was to determine the antimicrobial-susceptible phenotypes and genotypes of the circulating MRSA clone isolated in bovine mastits milk samples in Xinjiang, China.

[Prokaryotic expression and immunogenicity of IgG-binding protein of Streptococcus equi subspecies equi].

To analyze the immunogenicity and protective ability of recombinant IgG-binding protein (EAG) of Streptococcus equi subspecies equi and to evaluate its value when used as equine vaccine antigen, EAG gene was amplified by PCR and inserted into pET-28a vector. The EAG recombinant proteins were expressed and purified to immune mice. The serum antibody and challenge protection were tested.

In vivo HMRS and lipidomic profiling reveals comprehensive changes of hippocampal metabolism during aging in mice.

Aging is characterized by various cellular changes in the brain. Hippocampus is important for systemic aging and lifespan control. There is still a lack of comprehensive overview of metabolic changes in hippocampus during aging.

Parallel growing and training of neural networks using output parallelism.

In order to find an appropriate architecture for a large-scale real-world application automatically and efficiently, a natural method is to divide the original problem into a set of subproblems. In this paper, we propose a simple neural-network task decomposition method based on output parallelism. By using this method, a problem can be divided flexibly into several subproblems as chosen, each of which is composed of the whole input vector and a fraction of the output vector.
