Purpose: Kidney renal clear cell carcinoma(KIRC), the most common malignant tumor of the urinary system, is an immunogenic tumor, and KIRC patients therapeutic response and prognosis are relevant to immune infiltration. NDUFS1, the core subunit of mitochondria complex I(CI) in the respiratory chain, participating in the procedure of electron transport has been reported to be associated with the occurrence and development of tumors and be down-regulated in KIRC and associated with poor prognosis. However, the upstream regulator for NDUFS1 and their correlations with immune infiltration or patients survival remain unclear. Here, we tried to elucidate the immunological mechanism and clinical significance of NDUFS genes in ***: The expression of NDUFS genes in KIRC and their influences on patients survival were investigated by UALCAN, eNCORI(The encyclopedia of RNA Interactomes), GePIA(Gene expression Profiling Interactive Analysis), Oncomine, TIMeR(Tumor Immune estimation Resource site) and Kaplan-Meier Plotter. MiR NAs regulating NDUFS1 in KIRC were predicted and analyzed by TargetScan and eNCORI. The correlations between NDUFS1 or miRNAs expression with immune cell infiltration or gene marker sets of immune infiltrates were analyzed via TIMeR. The overall survival curves in high/low NDUFS1 or high/low hsa-miR-320 b expressed KIRC patients based on immune infiltration were analyzed via Kaplan-Meier ***: From comprehensive bioinformatic analysis through digging into public online databases, we consistently found that in NDUFS gene family, NDUFS1 was significantly down-regulated in KIRC,high expression of NDUFS1, NDUFS4 predict good overall survival(OS) prognosis, and high expression of NDUFS1, NDUFS2, and NDUFS4 are correlated with good disease-free survival(DFS)prognosis. Moreover, the expression of NDUFS1 negatively correlates with advanced tumor grades and individual cancer stages, demonstrating that NDUFS1 may serve as a tumor suppressor gene i

为制备高性能的热界面材料,采用非平衡分子动力学方法计算了三维石墨烯–碳纳米管复合结构的热学特性,研究了复合结构的尺寸及系统温度对于整体结构热导率的影响。研究表明,复合结构z方向长度的增加和温度的升高都能使复合结构的热导率在一定程度上增加并逐渐达到一个饱和值。为进一步探究整体及局部结构中声子能量传递的情况,计算了复合整体和连接处界面两侧的声子振动态密度,结果表明,碳纳米管与石墨烯界面处形变是阻碍复合结构热导率提高的主要因素。

Superhydrophobic surface was prepared on the zinc substrate by chemical solution method via immersing clean pure zinc substrate into a water solution of zinc nitrate hexahydrate[Zn（NO3）2.6H2O] and hexamethylenete- traamine（C6H12N4） at 95 ℃ in water bath for 1.5 h, then modified with 18 alkanethiol. The best resulting surface shows superhydrophobic properties with a water contact angle of about 158° and a low water roll-off angle of around 3°. The prepared samples were characterized by powder X-ray diffraction（XRD）, X-ray photoelectron spectroscopy （XPS）, energy-dispersive X-ray spectroscopy（eDX）, transmission electron microscopy（TeM）, and scanning electron microscopy（SeM）. SeM images of the films show that the resulting surface exhibits flower-shaped micro- and nano-structure. The surfaces of the prepared films were composed of ZnO nanorods which were wurtzite structure. The special flower-like micro- and nano-structure along with the low surface energy leads to the surface superhydro- phobicity.
