Aims: To investigate the N-glycans related to the metformin efficacy in patients with type 2 diabetes mellitus (T2DM).
Materials And Methods: We enrolled 141 healthy controls and 195 newly diagnosed T2DM patients treated with metformin for 3 months. Serum N-glycan profile was determined by DNA sequencer - assisted fluorophore-assisted carbohydrate electrophoresis (DSA-FACE).
Ethnopharmacological Relevance: The overuse of antibiotics has resulted in Clostridium difficile infection (CDI) as a significant global public health concern. Studies have shown that imbalances in gut microbiota and metabolism play a vital role in the onset of CDI. Shengjiang Xiexin decoction (SJT), a traditional Chinese medicinal formula widely employed in the treatment of gastrointestinal ailments, demonstrates effectiveness in addressing murine CDI.

Background: Quinolones are commonly used for reducing the duration of diarrhea, infection severity, and limiting further transmission of disease related to , but susceptibility to quinolone decreases over time. In addition to mutations in the quinolone-resistance determining regions (QRDRs), the presence of and other acquired genes also contributes to quinolone resistance.
Results: We determined the prevalence of quinolone resistance related genes among O139 strains isolated in China.

Soil bacterial diversity is a key factor for the maintanence of forest ecosystem function. Soil bacterial community would change along forest succession. We analyzed the variations of soil bacterial diversity and community composition at different successional stages in the forest, which would help understand the mechanism underlying forest restoration.

Previous studies have suggested that ginger, a common spice and herbal medicine, can modulate the composition of gut microbiota and is beneficial against gastrointestinal disease. This study investigates the therapeutic effects of fresh ginger extract on AAD in a rat model.

Minimum inhibitory concentrations (MICs) were determined by the broth microdilution method following Clinical and Laboratory Standards Institute (CLSI) guidelines. Cefoselis showed poor activity against extended-spectrum β-lactamase (ESBL)-producing , , and , with susceptibility rates of < 10% each, while the susceptibility rates of this antibiotic against non-ESBL-producing strains of these organisms were 100%, 94.

Lactobacilli have been shown to inhibit the proliferation of several types of cancer cells, but the effects of vaginal Lactobacilli on cervical cancer cells have seldom been reported. We incubated Caski cells with supernatants of predominant strains in the vagina and investigated their effects on cell growth and the possible mechanisms. Cell-free supernatants of Lactobacillus crispatus, L.

The title hydrated complex, [Cu(CHO)(CHN)](CHO)·7.5HO, is composed of dinuclear Cu complex cations, noncoordinating 4-hy-droxy-benzoate anions and water mol-ecules of crystallization. In the dinuclear complex cation, the Cu ions are bridged by a 4-oxidobenzoate ligand and thus each metal ion is five-coordinated by two chelating 1,10-phenanthroline (phen) mol-ecules and one anionic O atom in a distorted trigonal-bipyramid geometry.

Background: With the rapid expansion of infectious syphilis all over the world, optimal procedures for screening syphilis are urgently required. Conventional methods for the diagnosis of syphilis are time- and labor-consuming. We compared automated chemiluminescent micro-particle immunoassay (CLIA) with conventional methods to verify whether CLIA is feasible for syphilis screening.

Vancomycin is a preferred antibiotic for treating Clostridium difficile infection (CDI) and has been associated with a rate of recurrence of CDI of as high as 20% in treated patients. Recent studies have suggested that berberine, an alternative medical therapy for gastroenteritis and diarrhea, exhibits several beneficial effects, including induction of anti-inflammatory responses and restoration of the intestinal barrier function. This study investigated the therapeutic effects of berberine on preventing CDI relapse and restoring the gut microbiota in a mouse model.

Background: Vancomycin-resistant Enterococci (VRE) cause serious infections that are difficult to treat. We carried out this study to determine the mutant prevention concentration (MPC) of linezolid when combined with minocycline against VRE strains, to determine the mechanism of drug resistance in vitro, and to provide a theoretical basis for the rational use of drugs against VRE.
Methods: The minimum inhibitory concentrations (MICs) of linezolid and minocycline against 30 Enterococci (E.

Based on the investigation data of monsoon evergreen broad-leaved forest at its different succession stages (primary, CP; 15 years of succession, CF; and 30 years of succession, CT) in Pu' er of Yunnan Province, this paper studied the species-area relationship of this forest at each succession stage. It was found that in the communities at each succession stage, the number of total species, trees, shrubs, and lianas had a significant correlation with sampling area, with the area explained over 94% of the total variation. The Z value of the total species (0.

We established whether serum CXCL16 concentration or the A181V genotype is more strongly associated with atherosclerotic stroke and its associated risk factor, carotid atherosclerosis.
Methods: PCR-RFLP was used to genotype 244 atherosclerotic stroke patients (AS group), 153 stroke-free controls (patient controls) and 167 healthy controls.

Pex14p is a central component of the peroxisomal matrix protein import machinery. In the recently determined crystal structure, a characteristic face consisting of conserved residues was found on a side of the conserved N-terminal domain of the protein. The face is highly hydrophobic, and is also the binding site for the WXXXF/Y motif of Pex5p.

Pex14p is a central component of the peroxisomal protein import machinery, in which the conserved N-terminal domain mediates dynamic interactions with other peroxins including Pex5p, Pex13p, and Pex19p. Here, we report the crystal structure of the conserved N-terminal domain of Pex14p with a three-helix bundle. A hydrophobic surface is composed of the conserved residues, of which two phenylalanine residues (Phe-35 and Phe-52) protrude to the solvent.

The tetra-meric complex mol-ecule has symmetry. While two benzimidazole mol-ecules and a tridentate malate dianion coordinate a Co(II) ion, the carboxylate O atom from an adjacent malate dianion bridges the Co(II) ions to complete a distorted octa-hedral coordination geometry.

In the mononuclear species, the Ni(II) ion, located on an inversion center, is coordinated by two 1H-benzimidazole (bzim) ligands and two 3-hydroxy-benzoate (hba) anions in a square-planar geometry. In the centrosymmetric dinuclear species, the Ni(II) ion is coordinated by two bzim ligands and three hba anions in a square-pyramidal geometry; of the two independent hba anions, one bridges two Ni(II) ions with both carboxylate and hydroxyl groups whereas the other coordin-ates in a unidentate manner to the Ni(II) ion.
