Synthesizing ultrathin 2D metal-organic framework nanosheets in high yields has received increasing research interest but remains a great challenge. In this work, ultrathin zirconium-porphyrinic metal-organic framework (MOF) nanosheets with thickness down to ≈1.5 nm are synthesized through a pseudoassembly-disassembly strategy. Owing to the their unique properties originating from their ultrathin thickness and highly exposed active sites, the as-prepared ultrathin nanosheets exhibit far superior photocatalysis performance compared to the corresponding bulk MOF...

Atrial fibrosis serves as an important contributor to atrial fibrillation (AF). Recent data have suggested that microRNA-30c (miR-30c) is involved in fibrotic remodelling and cancer development, but the specific role of miR-30c in atrial fibrosis remains unclear. The purpose of this study was to investigate the role of miR-30c in atrial fibrosis and its underlying mechanisms through in vivo and in vitro experiments. Our results indicate that miR-30c is significantly down-regulated in the rat abdominal aortic constriction (AAC) model and in the cellular model of fibrosis induced by transforming growth factor-β1 (TGF-β1)...

BACKGROUND: Noninvasive biomarkers are urgently needed for patients with nonalcoholic steatohepatitis (NASH) to assist in diagnosis, monitoring disease progression and assessing treatment response. Recently several exploratory studies showed that circulating level of microRNA is associated with NASH and correlated with disease severity. Although these data were encouraging, the application of circulating microRNA as biomarkers for patient screening and stratification need to be further assessed under well-controlled conditions...

Pressure-induced spin crossover behaviors of Fe-bearing MgO were widely investigated by using LDA+U functional for describing the strongly correlated Fe-O bonding. Moreover, the simulated spin crossover pressures depend on the applied U values, which are sensitive to environments and parameters. In this work, the spin crossover pressures of (Mg1-x,Fex)O are investigated by using the hybrid functional with a uniform parameter. Our results indicate that the spin crossover pressures increase with the iron concentration increasing...

Despite of inherent advantages over synthetic polymer based counterparts, protein nanoparticles remain unsatisfactory in fabrication owing to low size control, usage of toxic cross-linker or organic solvents. This partially contributes the marginal benefits of Abraxane® in clinic. Herein, a green synthetic, size controlled approach was developed to generate stable albumin nanoparticles. Physically packed ovalbumin (OVA) nanoclusters were temporally formed in heat, which was then used as the template to form protein nanoparticle chemically stabilized by intermolecular disulfide network...

Food contaminated with pathogenic bacteria such as Staphylococcus aureus ( S. aureus ), represents a serious health risk to human beings. Totarol is an antibacterial novel phenolic diterpenes. In present study, the antibacterial activity of totarol against S. aureus was investigated in a food system. The antibacterial activity of totarol was determined by measuring the zones of inhibition and minimum inhibitory concentrations (MICs). The MICs for S. aureus strains were in the range of 2-4 μg/ml. The probable antibacterial mechanism of totarol was the alteration in cell membranes integrity and permeability, which leading to the leakage of cellular materials...

Mycobacterium abscessus accounts for a large proportion of lung disease cases caused by rapidly growing mycobacteria. The association between clarithromycin sensitivity and treatment outcome is clear. However, M. abscessus culture and antibiotic susceptibility testing are time-consuming. Clarithromycin-susceptibility genotyping offers an alternate, rapid approach to predicting the efficacy of clarithromycin-based antibiotic therapy. M. abscessus lung disease patients were divided into two groups based upon the clarithromycin-susceptibility genotype of the organism isolated...
