The Investigation of Function of Mineral Mud for the Skin
Yijie Du,Xiaofeng Deng,Li Li,Yinmao Dong 한국피부과학연구원 2016 아시안뷰티화장품학술지 Vol.14 No.1
목적: 본 연구는 미네랄머드가 류머티스성 질환, 건선 등 질병에 민간적 응용과 임상적 응용으로 많이 사용됨에 따 라 미네랄머드의 피부 임상응용을 목적으로 연구를 진행하였다. 방법: 미네랄머드의 소염, 항산화 작용을 요약하고, 미네랄머드를 화장품에 응용함에 있어서 존재하는 문제를 발 견하고 화장품영역에서의 발전방향을 제시하였다. 결과: 류머티스성 질환, 건선 등 난치 성 피부병의 치료는 미네랄머드의 소염, 항산화작용에 의한 것으로 보인다. 결론: 미네랄머드가 화장품 소재로서의 희망적인 가능성을 가지고 있지만 화장품 완제품으로 개발하기 위해서는 아직도 해결해야 할 여러 문제점들이 있다고 사료된다. Purpose: The treatment of mineral mud in rheumatic disease, psoriasis and other disease has been widely recognized in clinic application. We aim to explore the effect of mineral mud on the skin through it clinic application. Methods: We summarize the function of mineral mud in anti-inflammation, anti-oxidation, et al and point out the existing in the application of mineral mud in cosmetics and its development status. Results: Mineral mud have positive effects on rheumatic diseases through its properties of anti-inflammatory and anti-oxidation. Conclusion: The results demonstrate that mineral mud had a good prospect in cosmetics, but there are still many problems to be solved.

Alterations of oral microbiota in Chinese children with viral encephalitis and/or viral meningitis
Li Yijie,Liu Jing,Zhu Yimin,Peng Chunying,Dong Yao,Liu Lili,He Yining,Lu Guoping,Zheng Yingjie 한국미생물학회 2022 The journal of microbiology Vol.60 No.4
The role of oral microbiota in viral encephalitis and/or viral meningitis (VEVM) remains unclear. In this hospital-based, frequency-matched study, children with clinically diagnosed VEVM (n = 68) and those with other diseases (controls, n = 68) were recruited. Their oral swab samples were collected and the oral microbiota was profiled using 16S rRNA gene sequencing. The oral microbiota of children with VEVM exhibited different beta diversity metrics (unweighted UniFrac distance: P < 0.001, R2 = 0.025, Bray-curtis dissimilarity: P = 0.045, R2 = 0.011, and Jaccard dissimilarity: P < 0.001, R2 = 0.017) and higher relative abundances of taxa identified by Linear discriminant analysis (LDA) with effect size (Enterococcus, Pedobacter, Massilia, Prevotella_9, Psychrobacter, Butyricimonas, Bradyrhizobium, etc., LDA scores > 2.0) when compared with the control group. The higher pathway abundance of steroid hormone biosynthesis predicted by oral microbiota was suggested to be linked to VEVM (q = 0.020). Further, a model based on oral microbial traits showed good predictive performance for VEVM with an area under the receiver operating characteristic curve of 0.920 (95% confidence interval: 0.834–1.000). Similar results were also obtained between children with etiologically diagnosed VEVM (n = 43) and controls (n = 68). Our preliminary study identified VEVM-specific oral microbial traits among children, which can be effective in the diagnosis of VEVM.

Drought stress, as a key negative factor, could result in the reduction of yield and quality in rice. Myo-inositol oxygenase (MIOX), a unique monooxygenase, exerts an essential role in plant drought resistance. To investigate the function of the OsMIOX gene in drought process, a transcriptomic profile between OsMIOX-overexpressing (OE) plants and wild-type (WT) was performed by RNA-sequencing in rice. Under drought stress, a total of 23 million high-quality reads, assembled into 28,552 unigenes, were generated and 743 genes (534 up-regulated and 209 down-regulated) were significantly differentially expressed between OE plants and WT. These detected genes were mainly associated with plant hormones transduction and sugar metabolism. Interestingly, several transcription factors (TFs) were prominently identified in OE lines. A significant positive correlation between RNA-Seq data and qRT-PCR results was identified. In all, our results could partially provide relatively valuable clues in identifying candidate genes involved in drought-stress resistance and elucidating basis theory underlying the role of OsMIOX in drought resistance.

High volatile bituminous coal applied to Melter-Gasifier may change combustion characteristics due to agglomeration. The purpose of this study is to investigate the effect of high volatile coal bituminous coal agglomeration on the thermochemical behavior inside the furnace. The three-dimensional CFD model includes a pulverized coal injection system, raceway, and surrounding coke bed area. This results show that even with high volatile bituminous coal, the occurrence of lumps reduces flammability and that the Melter-Gasifier cannot supply sufficient heat for iron ore reduction.
