UNLABELLED Background/Aims: Laparoscopic cholecystectomy (LC) has become the gold standard for treating sy¬m¬ptomatic cholelithiasis. However, there are still some risk factors will lead to conversion to o¬p¬en cholecystectomy. The main aim of this meta-analysis is to evaluate preoperative risk fact¬o¬rs for converting laparoscopic to open cholecystectomy(More)
Combustion catalysts have been extensively explored to reduce the emission of hydrocarbons that are capable of triggering photochemical smog and greenhouse effect. Palladium as the most active material is widely applied in exhaust catalytic converter and combustion units, but its high capital cost stimulates the tremendous research on non-noble metal(More)
A meta-analysis was performed to evaluate the effect of oestrogen receptor-alpha (ESR1) gene PvuII polymorphism on fracture risk. It included published data from relevant studies (up to May 2010) identified from Medline, Embase and Current Contents. The 13 included studies contained 1279 fracture cases and 6069 controls. The combined results based on these(More)
Our previous study demonstrated that microRNA 5100 (miR-5100) is overexpressed in lung cancer tissues; however, the function of miR-5100 remained elusive. In this study, we demonstrate that miR-5100 is highly expressed in a wide variety of lung cancer tissues and lung cancer cell lines. Exogenous expression of miR-5100 in A549 and H1299 lung cancer cells(More)
The exterior and interior of plants, aboveground and belowground, comprise a complex plant micro-ecosystem, known in recent years as the phytosphere. There are three components: the phyllosphere, endosphere, and rhizosphere. Although in comparison with other ecosystems the phytosphere is small, it similarly includes a great variety of functional microbes.(More)
FBXO31 is a member of F-box family which is involved in diverse biological functions and development of disease. Recent reports in breast cancer, hepatocellular carcinoma and ovarian cancer demonstrated inhibitory effect of FBXO31 on proliferation and tumorigenesis. However, the function of FBXO31 is not analyzed in lung cancer so far. In this study, we(More)
We combine scanning tunneling microscopy (STM) measurements with ab initio calculations to study the self-assembly of long chain alkanes and related alcohol and carboxylic acid molecules on graphite. For each system, we identify the optimum adsorption geometry and explain the energetic origin of the domain formation observed in the STM images. Our results(More)
Many studies have examined pair-wise interactions between plants and endophytes, while overlooking the interplays among multiple endosymbionts and their combined impacts on hosts. In this study, Atractylodes lancea plantlets were inoculated with endophytic fungus Acremonium strictum AL16, or endophytic bacterium Acinetobacter sp., or both, to investigate(More)
Propofol (2,6-diisopropylphenol) is an anaesthetic agent with anti-oxidant properties. The aim of the present study was to determine whether propofol can protect pulmonary epithelial (A549) cells against lipopolysaccharide (LPS)-induced cell death and, if so, the mechanisms involved. The effects of LPS alone and in combination with propofol on A549 cell(More)
The aim is to investigate the molecular mechanisms underlying the PM2.5-induced autophagy in human lung cancer epithelial cells (A549). The effects of the PM2.5 on morphological and biochemical markers of autophagy in A549 were analyzed by electron microscopy, GFP-LC3 puncta was observed by confocal fluorescence microscope. The effects of phosphorylation of(More)
