Serum metabolomic profiles in BALB/c mice induced by infection.

Introduction: The protozoan parasite is the primary cause of human babesiosis. This parasite invades and multiplies inside red blood cells (RBCs), and infections differ significantly based on the age and immune competency of the host. The aim of this study was to investigate the use of serum metabolic profiling to identify systemic metabolic variations between -infected mice and noninfected controls.

Identification and Evolutionary Relationship of Clinical Isolates.

has developed into a new community-acquired and hospital-acquired multi-drug resistance (MDR) bacterium, and is a potential target pathogen for infection control and antibacterial management projects. In this study, non-duplicate samples of inpatients were collected from a local central hospital. Mass spectrometry showed that 54 isolates mainly appeared in secretion and sputum from 14 departments.

Preparation and characterization of 2-deacetyl-3-O-sulfo-heparosan and its antitumor effects via the fibroblast growth factor receptor pathway.

Heparosan, with a linear chain of disaccharide repeating units of → 4) β-D-glucuronic acid (GlcA) (1 → 4)-α-D-N-acetylglucosamine (GlcNAc) (1→, is a potential starting chemical for heparin synthesis. However, the chemoenzymatic synthesis of single-site sulfated heparosan and its antitumor activity have not been studied. In this study, 2-deacetyl-3-O-sulfo-heparosan (DSH) was prepared successively by the N-deacetylation chemical reaction and enzymatic modification of human 3-O-sulfotransferase-1 (3-OST-1).

Zona pellucida blocks adenovirus from entering porcine oocytes.

Adenovirus is a kind of non-enveloped,double-stranded DNA virus. As a member of the mammalian adenoviruses of the Adenoviridae family, porcine adenovirus causes gastrointestinal disease in piglets. In this study, the modified adenovirus was manipulated to carry a green fluorescence EGFP marker.

Transcriptomic analysis reveals differential gene expressions for cell growth and functional secondary metabolites in induced autotetraploid of Chinese woad (Isatis indigotica Fort.).

The giant organs and enhanced concentrations of secondary metabolites realized by autopolyploidy are attractive for breeding the respective medicinal and agricultural plants and studying the genetic mechanisms. The traditional medicinal plant Chinese woad (Isatis indigotica Fort., 2n = 2x = 14) is now still largely used for the diseases caused by bacteria and viruses in China.
