Representing words into vectors in continuous space can form up a potentially powerful basis to generate high-quality textual features for many text mining and natural language processing tasks. Some recent efforts, such as the skip-gram model, have attempted to learn word representations that can capture both syntactic and semantic information among text(More)
Serum microRNAs have been identified as potential cancer biomarkers. However, the detailed mechanism by which expression of microRNAs contributes to the development and diagnosis of NSCLC remains unknown. This study was to identify specific miRNAs for diagnosing or predicting the prognosis of NSCLC patients and their correlation between miRNA expression in(More)
Clostridium tyrobutyricum produces butyrate, acetate, H(2), and CO(2) as its main fermentation products from glucose and xylose. To improve butyric acid and hydrogen production, integrational mutagenesis was used to create a metabolically engineered mutant with inactivated ack gene, encoding acetate kinase (AK) associated with the acetate formation pathway.(More)
Although circulating microRNAs (miRNAs) were frequently detected in sera of cancer patients, there is still a lack of analysis of the dynamic changes of miRNAs expression in sera of pre- and post-operative lung carcinoma patients. Thus, we conducted quantitative reverse transcription-polymerase chain reaction (qRT-PCR) to examine the expression of four(More)
Clostridium tyrobutyricum ATCC 25755 is an acidogenic bacterium, producing butyrate and acetate as its main fermentation products. In order to decrease acetate and increase butyrate production, integrational mutagenesis was used to disrupt the gene associated with the acetate formation pathway in C. tyrobutyricum. A nonreplicative integrational plasmid(More)
BACKGROUND Lung cancer is the leading cause of cancer-related deaths worldwide. Early detection is considered critical for lung cancer treatment. MicroRNAs (miRNAs) have shown promise as diagnostic and prognostic indicators. This study was to identify specific miRNAs with diagnostic and prognostic value for patients with lung cancer, and to explore the(More)
This paper presents octave-tunable resonators and filters with surface mounted lumped tuning elements. Detailed theoretical analysis and modeling in terms of tuning range and unloaded quality factor (Qu) are presented in agreement with simulated and measured results. Based on the models, a systematic design method to maximize tuning ratio and optimize Qu of(More)
The biocontrol activity of various fluorescent pseudomonads towards plant-pathogenic fungi is dependent upon the GacA/GacS-type two-component system of global regulators and the RpoS transcription sigma factor. In particular, these components are required for the production of antifungal antibiotics and exoenzymes. To investigate the effects of these global(More)
The ten-eleven translocation (TET) family of dioxygenases (TET1/2/3) converts 5-methylcytosine to 5-hydroxymethylcytosine and provides a vital mechanism for DNA demethylation. However, how TET proteins are regulated is largely unknown. Here we report that the O-linked β-GlcNAc (O-GlcNAc) transferase (OGT) is not only a major TET3-interacting protein but(More)
A xylanase gene (xynG1-1) from Paenibacillus campinasensis G1-1 was expressed in Bacillus megaterium MS941 and a high level of extracellular xylansae activity (304.26 IU/mL) was achieved after induction with 0.5% xylose. The purified recombinant xylanase (XynG1-1R) revealed optimal activity at 60°C and pH 7.0 and retained 79% and 81% activity after(More)
