Background: Although significant advances have been made in understanding the mechanisms of macrophage response to Staphylococcus aureus infection, the molecular details are still elusive. Identification of the essential genes and biological processes of macrophages that are specifically changed at different durations of S. aureus exposure is of great clinical significance. Methods: We aimed to identify...
Background: Epstein–Barr virus (EBV) infection is causatively associated with a variety of human cancers, including gastric cancer (GC), which has one of the highest mortality rates of all human cancers. Long non-coding RNAs (lncRNAs) show important regulatory roles in human GC. SNHG8 is a recently identified lncRNA that was reported to show abnormal expression pattern in GC. However, little is known...
Near infrared spectroscopy and interval partial least-squares (iPLS) were applied to rapid quantitative analysis of thepoly-β-hydroxybutyrate (PHB), polyphosphate (Poly-P), and glycogen (Gly) during denitrifying phosphorus removal. Wavelet denoising was used to pretreat the raw near infrared spectroscopy, and the quantitative analysis models (iPLS models) of PHB, Poly-P, and GLY were established with...
MLSS and SRT are key parameters in process control. A full-scale modified A2/O process varying with MLSS and SRT was evaluated, and MLSS and SRT effect was distinguished by statistical methods so as to seek early diagnosis and efficient control. Results showed that complete SRT rather than MLSS resulted in considerable effluent SS fluctuation with inert SS accumulation. COD removal was more sensitive...
Surface water samples were collected from 24 sampling sites throughout the Le’an River during wet and dry seasons. The concentrations of dissolved heavy metals were determined by inductively coupled plasma-mass spectrometry (ICP-MS). The sources of dissolved heavy metals in the Le’an River were investigated based on the seasonal and spatial variations. The results demonstrated that significant seasonality...
The phloem-unloading pathway of sucrose and mechanism of sugar-to-oil transition are still unknown in Camellia oleifera Fruit. Here, transmission electronic microscopy (TEM) and confocal laser-scanning microscopy (CLSM) were used to observe the cellular structure of vascular bundles and symplastic tracer, carboxyfluorescein (CF), transport in phloem zone. The results showed that sucrose was transported...
An intermittent aerobic process has been developed to effectively remove nitrogen from polluted rivers. In addition, a chemometric model was developed to achieve simultaneous rapid analysis of total nitrogen, ammonia nitrogen, and nitrite nitrogen based on near-infrared spectroscopy data combined with a support vector machine. An intermittent aeration process showed that total nitrogen decreased from...
With the rapid development of electronic technology, network technology and cloud computing technology, the current data is increasing in the way of mass, has entered the era of big data. Based on cloud computing clusters, this paper proposes a novel method of parallel implementation of multilayered neural networks based on Map-Reduce. Namely in order to meet the requirements of big data processing,...
As scattered elements, thallium (Tl) contamination poses a significant threat to human health due its high toxicity. Sulfate-reducing bacteria (SRB) embedded in PVA-sodium alginate matrix was utilized as a novel bio-remover to remove Tl from aqueous solution. The effect of pH, temperature, and initial Tl concentration on removal capacity of immobilized beads were studied and discussed in this work...
The present study used the method of embedding-adsorption to immobilize fungal laccase and to determine the suitable conditions of immobilization by measuring various activities of immobilized laccase. In addition, the immobilized laccase was further employed to repair the carbofuran-contaminated soil, and then the degradation rates of carbofuran were measured under different conditions. The experimental...
Arsenic (As) is a ubiquitous carcinogen in the environment. Its bio-toxicity is significantly correlated with its chemical forms. In this study, As accumulation and speciation of PM₂.₅ was investigated in Jinan. The high PM₂.₅ levels fluctuated between 69.67 μg·m⁻³ and 211.25 μg·m⁻³ in winter, and ranged from 63.46 μg·m⁻³ to 125.50 μg·m⁻³ in summer. The total As concentration of PM₂.₅ in winter and...
