Synergistic bactericidal activities of tobramycin with ciprofloxacin and azithromycin against Klebsiella pneumoniae.

Trans-translation is a unique bacterial ribosome rescue system that plays important roles in the tolerance to environmental stresses. It is composed of an ssrA-encoded tmRNA and a protein SmpB. In this study, we examined the role of trans-translation in antibiotic tolerance in Klebsiella pneumoniae and explored whether the inhibition of this mechanism could enhance the bactericidal activities of antibiotics.

Combination of Azithromycin and Gentamicin for Efficient Treatment of Pseudomonas aeruginosa Infections.

Background: Trans-translation is a ribosome rescue system that plays an important role in bacterial tolerance to environmental stresses. It is absent in animals, making it a potential treatment target. However, its role in antibiotic tolerance in Pseudomonas aeruginosa remains unknown.

Morin protects glucocorticoid-induced osteoporosis through regulating the mitogen-activated protein kinase signaling pathway.

Our aim is to investigate the potential therapeutic value of morin against osteoporosis and elucidate the mechanism of action. Osteoporosis was induced in rats by a subcutaneous injection of dexamethasone (DEX) for 5 weeks. Body weight was regularly monitored.

The prognostic value of p62 in solid tumor patients: a meta-analysis.

p62, as a scaffolding/adaptor protein, is involved in multiple physiological processes include inflammation, autophagy and mitosis. However, the influence of p62 in cancer patients has not been comprehensively investigated. Moreover, the prognostic value of p62 for the survival of patients with solid tumors remains controversial.

Acute and chronic effects of taurine magnesium coordination compound on cardiac sodium channel Nav1.5.

It has been previously demonstrated that taurine magnesium coordination compound (TMCC) produces antiarrhythmic effects in vivo. The present study investigated the acute and chronic effect of TMCC on sodium channels in HEK cells stably expressing human cardiac Nav1.5 sodium channels.

The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients.

Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients.

[High D-glucose alters PI3K and Akt signaling and leads to endothelial cell migration, proliferation and angiogenesis dysfunction].

Objective: To investigate the effects of high D-glucose on migration, proliferation, and angiogenesis of endothelial cells and to make sure whether PI3K and Akt signaling pathway plays an important role in the pathogenesis of diabetic vascular complications.

Methods: Human umbilical vein endothelial cells (HUVECs) were cultured. D-glucose of the concentrations of 5 mmol/L, 15 mmol/L, and 30 mmol/L and mannitol of the concentrations of 5 mmol/L, 15 mmol/L, and 30 mmol/L were added in to the medium, the migration rate of the cells was measured by wound healing test and the cell proliferation was examined with CellTiter 96 AQ(ueous) One Solution cell proliferation assay.
