Single nucleotide polymorphisms located at microRNA (miRNA)-binding sites are likely to affect the expression of miRNA targets and may contribute to the susceptibility of humans to common diseases. Here 335 candidate lung cancer-related inflammatory genes were selected according to the existing literature and database. We identified putative miRNA-binding sites of 149 genes by specialised algorithms and screened SNPs in the 3'UTRs of these genes. By calculating binding free energy, we sorted 269 SNPs on the basis of the possibility of prediction. The proposed approach could help to easy the identification of functionally relevant SNPs and minimize the workflow and the costs.

Degradation of reinforced concrete (RC) structures due to chloride penetration followed by reinforcement corrosion has been a serious problem in civil engineering for many years. The numerical simulation methods at present are mainly finite element method (FEM) and finite difference method (FDM), which are based on mesh. Mesh generation in engineering takes a long time. In the present article, the numerical solution of chloride transport in concrete is analyzed using radial point interpolation method (RPIM) and element-free Galerkin (EFG). They are all meshless methods. RPIM utilizes radial polynomial basis, whereas EFG uses the moving least-square approximation. A Galerkin weak form on global is used to attain the discrete equation, and four different numerical examples are presented. MQ function and appropriate parameters have been proposed in RPIM. Numerical simulation results are compared with those obtained from the finite element method (FEM) and analytical solutions. Two case of chloride transport in full saturated and unsaturated concrete are analyzed to test the practical applicability and performance of the RPIM and EFG. A good agreement is obtained among RPIM, EFG, and the experimental data. It indicates that RPIM and EFG are reliable meshless methods for prediction of chloride concentration in concrete structures.

Active distribution system (ADS) considering distributed generation (DG) and electric vehicle (EV) is an effective way to cut carbon emission and improve system benefits. ADS is an evolving, complex and uncertain system, thus comprehensive model and effective optimization algorithms are needed. Battery swapping station (BSS) for EV service is an essential type of flexible load (FL). This paper establishes ADS planning model considering BSS firstly for the minimization of total cost including feeder investment, operation and maintenance, net loss and carbon tax. Meanwhile, immune binary firefly algorithm (IBFA) is proposed to optimize ADS planning. Firefly algorithm (FA) is a novel intelligent algorithm with simple structure and good convergence. By involving biological immune system into FA, IBFA adjusts antibody population scale to increase diversity and global search capability. To validate proposed algorithm, IBFA is compared with particle swarm optimization (PSO) algorithm on IEEE 39-bus system. The results prove that IBFA performs better than PSO in global search and convergence in ADS planning.

Allergic asthma, is a common chronic inflammatory disease of the airway presenting with airway hyperresponsiveness and airway remodelling. T helper cells-derived cytokines are critically associated with asthma pathogenesis. Janus kinase-signal transduction and activation of transcription (JAK/STAT) signaling is found to be involved in asthma. Magnolol is a plant-derived bioactive compound with several pharmacological effects. The study aimed to assess the effects of magnolol in ovalbumin (OVA)-induced asthmatic model. BALB/c mice were sensitized and challenged with OVA. Magnolol (12.5, 25, or 50 mg/kg body weight) was administered to separate groups of animals. Dexamethasone was used as the positive control. Cellular infiltration into the bronchoalveolar lavage fluid (BALF) were reduced on magnolol treatment. The levels of Th2 and Th17 cytokines were reduced with noticeably raised levels of interferon gamma. Lung function was improved effectively along with restoration of bronchial tissue architecture. OVA-specific immunoglobulin E levels in serum and BALF were decreased by magnolol. Magnolol reduced Th17 cell population and effectively modulated the JAK-STAT and Notch 1 signaling. The results suggest the promising use of magnolol in therapy for allergic asthma.

In this study, Monte Carlo (MC) simulation is conducted with recurrence relation to study the effect of SiO₂ with different particle size and their roles in enhancing the ionic conductivity and lithium transference number of PMMA composite polymer electrolytes (CPEs). The MC simulated ionic conductivity is verified with the measurements from Electrochemical Impedance Spectroscopy (EIS). Then, the lithium transference number of CPEs is calculated using recurrence relation with the MC simulated current density and the reference transference number obtained. Incorporation of micron-size SiO₂ (≤10 ㎛) fillers into the mixture improves the ionic conductivity from 8.60×10^-5 S/cm to 2.35×10^-4 S/cm. The improvement is also observed on the lithium transference number, where it increases from 0.088 to 0.3757. Furthermore, the addition of nano-sized SiO₂ (≤12 nm) fillers further increases the ionic conductivity up towards 3.79×10^-4 S/cm and lithium transference number of 0.4105. The large effective surface area of SiO₂ fillers is responsible for the improvement in ionic conductivity and the transference number in PMMA composite polymer electrolytes.

A case of a 75-year-old Korean female with gait disturbance due to Normal pressure hydrocephalus (NPH) is presented. She was treated with acupuncture, electroacupuncture and herbal medicine - 柴苓湯(Shirhyung-Tang, Chai-ling-tang, Sairei-to) We used iNPH grading scale, and specified further the grade of gait disturbance category. After Korean medical treatment, there was notable improvement in gait disturbance on our specified scale. Cognitive impairment, tremor and rigidity were improved on each scale alongside. Korean medical treatment may be effective in treating NPH patients.

This essay is dealing with Yang-Ming Studies' fundamental ideas, which are the goal of learning, the cultivation theory, and the ultimate goal in Yang-Ming-Xin-Xue. The first, what is the goal of learning in Yang-Ming-Xin-Xue: It is generally accepted idea that the goal of learning in Yang-Ming-Xin-Xue is to be a sage. But there are different suggestions about the ideas above. The reason is like this: Zhu-Zi-Studies was eager to be a sage through its cultivation theory. Yang-Ming-Xin-Xue criticized the cultivation theory in Zhu-Zi-Studies. Therefore, some people don't agree with the idea that the goal of learning in Yang-Ming-Xin-Xue is to be a sage. In this essay, I try to demonstrate that the goal of learning in Yang-Ming-Xin-Xue is to be a sage. The second, What is the major cultivation theory in Yang-Ming-Xin-Xue: The core cultivation theory is the Zhi-Ling-Zhi(Fulfillment Innate Knowledge of Goodness). For this, there is no question, but it is difficult how to learn and practice Zhi-Ling-Zhi in the daily life. I try to explain the right meaning and practice over Zhi-Ling-Zhi. The third, what is the ultimate goal in Yang-Ming-Xin-Xue: It is general method in examine Yang-Ming-Xin-Xue that is comparing with Zhu-Zi-Studies. So there is a natural tendency focusing on the differences and similarity between Yang-Ming-Xin-Xue and Zhu-Zi-Studies. But If I say, what is the ultimate goal in Yang-Ming-Xin-Xue? That is the realization of Ren, Which is the harmony with all things in heaven and earth.
