Cancer Research Advances Regarding the CKLF-like MARVEL Transmembrane Domain Containing Family
Lu, Jia,Wu, Qian-Qian,Zhou, Ya-Bo,Zhang, Kai-Hua,Pang, Bing-Xin,Li, Liang,Sun, Nan,Wang, Heng-Shu,Zhang, Song,Li, Wen-Jian,Zheng, Wei,Liu, Wei Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.6
The CKLF-like MARVEL transmembrane domain-containing family (CMTM) is a novel family of genes first reported at international level by Peking University Human Disease Gene Research Center. The gene products act between chemokines and the transmembrane-4 superfamily. Located in several human chromosomes, the CMTMs CKLF and CMTM1 to CMTM8 may be unregulated in tumors and act as potential tumor suppressor genes with important roles in the immune, male reproductive and hematopoietic systems. In-depth studies in recent years established a close relation between CMTMs and tumorigenesis and metastasis. The CMTM family has a significant clinical value in diagnosis and treatment of diseases linked to tumors and the immune system.
Graphitic Carbon Nitride Isotype Heterostructures with Enhanced Visible Photocatalytic Properties
Lujia Cong,Hongchen Mu,Shan Zhang,Mingyi Zhang,Zhenyu Zhao,Shufang Fu 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2017 NANO Vol.12 No.4
In this work, highly active graphitic carbon nitride composite photocatalysts with an isotype heterojunction semiconductor structure have been prepared through the molecular composite precursors consisting of urea and melamine. These photocatalysts were characterized by XRD, SEM, TEM, UV-Vis, BET and transient photocurrent responses. The photodegradation of dyes in aqueous solution under visible-light irradiation has been investigated over carbon nitride photocatalysts consisting of different urea/melamine mass ratios. Further studies by photocurrent indicate that the photosynergistic effect of isotype heterojunction can remarkably enhance the photoinduced interfacial charge transfer, thereby increasing the charge separation during the photocatalytic reaction.
Equivalent Circuit Based Design of an Integrated 2DoF Machine for Submerged Drilling Systems
Lujia Xie,Haichao Feng,Jikai Si,Yihua Hu,Kai Ni 한국자기학회 2019 Journal of Magnetics Vol.24 No.1
Drilling is traditionally performed by multi-motor systems manually. However, the complex intermediate transmission mechanisms in the traditional design have large size and relatively low robustness. In this paper, a splitstator 2-degree-of freedom (2DoF) machine is applied. By conducting linear, rotary, and helical motion by only one machine, it provides a more compact, more integrated, more reliable, and stronger-adaptability electrically drilling machine for submerged drilling systems. On account of the adoption of the split-stator structure, the electromagnetic design of such 2DoF machine is a significant challenge. In this paper, a design method for the 2DoF machine with special split structure is proposed based on the electric decoupled equivalent circuit (EDEC). Then a 1.5 ㎾ 2DoF drilling machine is designed, and the electromagnetic performances are verified by the 3D finite element analysis (FEA). The results show the good characteristics and feasibility of applying the 2DoF machine in drilling systems.

Jikai Si,Lujia Xie,Junbo Han,Haichao Feng,Wenping Cao,Yihua Hu 대한전기학회 2017 Journal of Electrical Engineering & Technology Vol.12 No.3
The two-degree-of-freedom direct drive induction motor, which is capable of linear, rotary and helical motion, has a wide application in special industry such as industrial robot arms. It is inevitable that the linear motion and rotary motion generate coupling effect on each other on account of the high integration. The analysis of this effect has great significance in the research of two-degreeof- freedom motors, which is also crucial to realize precision control of them. The coupling factor considering the coupling effect is proposed and addressed by 3D finite element method. Then the corrected mathematical model is presented by importing the coupling factor. The results from it are verified by 3D finite element model and prototype test, which validates the corrected mathematical model.

The global increase of cutaneous wounds imposes huge health and financial burdens on patients and society. Despite improved wound healing outcomes, conventional wound dressings are far from ideal, owing to the complex healing process. Smart wound dressings, which are sensitive to or interact with changes in wound condition or environment, have been proposed as appealing therapeutic platforms to effectively facilitate wound healing. In this review, the wound healing processes and features of existing biomaterials are firstly introduced, followed by summarizing the mechanisms of smart responsive materials. Afterwards, recent advances and designs in smart and versatile materials of extensive applications for cutaneous wound healing were submarined. Finally, clinical progresses, challenges and future perspectives of the smart wound dressing are discussed. Overall, by mapping the composition and intrinsic structure of smart responsive materials to their individual needs of cutaneous wounds, with particular attention to the responsive mechanisms, this review is promising to advance further progress in designing smart responsive materials for wounds and drive clinical translation.
