Interaction between gut microbiota dysbiosis and lung infection as gut-lung axis caused by Streptococcus suis in mouse model.

Streptococcus suis (S. suis) is an important zoonotic pathogen threatening the global pig farming industry. It causes respiratory and digestive tract infections simultaneously in pigs.

The role of visfatin on the regulation of inflammation and apoptosis in the spleen of LPS-treated rats.

The purpose of the present study is to determine if visfatin is involved in inflammation or apoptosis induced by LPS in rat. Forty Wistar rats were divided into four groups: saline group, LPS group, visfatin group and Visfatin + LPS co-stimulated group. Spleen samples from each group of rats were collected for study.

Clostridium difficile carriage in hospitalized cancer patients: a prospective investigation in eastern China.

Background: Clostridium difficile carriage has been considered as a potential source for the deadly infection, but its role in cancer patients is still unclear. We aimed to identify the clinical and immunological factors that are related to C. difficile carriage in Chinese cancer patients.

Exploration of molecular mechanisms of diffuse large B-cell lymphoma development using a microarray.

Objective: We aimed to identify key genes, pathways and function modules in the development of diffuse large B-cell lymphoma (DLBCL) with microarray data and interaction network analysis.

Methods: Microarray data sets for 7 DLBCL samples and 7 normal controls was downloaded from the Gene Expression Omnibus (GEO) database and differentially expressed genes (DEGs) were identified with Student's t-test. KEGG functional enrichment analysis was performed to uncover their biological functions.

[Serum myeloperoxidase activity and serum paraoxonase-1 activity in patients with silicosis and observation subjects and their clinical significance].

Objective: To investigate the serum myeloperoxidase (MPO) activity and serum paraoxonase-1 (PON-1) activity in patients with silicosis and observation subjects and their clinical significance.

Methods: Seventy-two patients with silicosis (stage I: 30 cases, stage II: 22 cases, stage III: 20 cases) and 37 observation subjects were selected as a case group, and 110 healthy men were selected as a control group. Serum MPO activity was measured by double-antibody sandwich enzyme-linked immunosorbent assay, and serum PON-1 activity was measured by chemical spectrophotometry.

[Elemental analysis and infrared spectra of suspended substance in the effluent from eco-biofilter].

The suspended substance (SS) in the effluent from eco-biofilters was examined by elemental analysis and infrared spectroscopy. The inorganic components of SS in D1 and S1 are more than those in D2 and S2, respectively. The IR spectra of SS is mainly composed of the adsorption of carbohydrates, protein, etc.

[Infrared spectroscopic investigation on complexes formed from cupric fluoborate and cupric butyrate with Bis (diphenylphosphino) alkane ligands].

The Bis (diphenylphosphino) alkane series ligands and its series of complexes formed from Cu(BF4)2 and Cu(C3H7COO)2 respectively were studied by infrared spectral analysis. This paper discusses the spectral classification and the change regularity of related spectra before and after the Cu(I) complexes were formed. The possible structure model of the formed complexes was discussed, based on the element analysis, powder X-ray diffraction analysis, and thermal gravity analysis.
