Ecdysteroids play an important role in the regulation of molting process in crustaceans. The suppression subtractive hybridization (SSH) technique was employed to search for 20-hydroxyecdysone-responsive genes in the hepatopancreas of the crayfish Procambarus clarkii. Ninety-three putative expressed sequence tags were identified by SSH, including three immune response-related genes, two cell cycle and apoptosis genes, four respiration and energy metabolism genes, four transport-related genes, six metabolism-related genes, two stress response genes, and eight transcription and translation regulation genes. The expression levels of the examined genes were regulated by 20-hydroxyecdysone and varied in the hepatopancreas during the molting stages; data were confirmed by real-time PCR. RNAi of the ecdysteroid receptor had significant effects on the expression levels of 20-hydroxyecdysone- responsive genes. These differentially expressed genes identified by SSH will provide insight into the ecdysteroid signaling pathway in P. clarkii.

Bao-yong Lai,Hui-juan Cao,Guo-yan Yang,Li-yan Jia,Suzanne Grant,Yu-tong Fei,Emma Wong,Xin-lin Li,Xiao-ying Yang,Jian-ping Liu 대한남성과학회 2019 The World Journal of Men's Health Vol.37 No.3

ChinaPurpose: To assess the effectiveness and safety of acupuncture for erectile dysfunction (ED).Materials and Methods: We searched six major English and Chinese databases included randomized controlled trials (RCTs) testing acupuncture alone or in combination for ED. Dichotomous data were presented as risk ratio (RR) and continuous data were presented as mean difference (MD) both with 95% confidence interval (CI). The Revman (v.5.3) was used for data analyses. Quality of evidence across studies was assessed by the online GRADEpro tool.Results: We identified 22 RCTs, fourteen of them involving psychogenic ED. Most of the included RCTs had high or unclear risk of bias. There was no difference between electro-acupuncture and sham acupuncture with electrical stimulation on the rate of satisfaction and self-assessment (RR, 1.50; 95% CI, 0.71–3.16; 1 trial). Acupuncture combined with tadalafil appeared to have better effect on increasing cure rate (RR, 1.31; 95% CI, 1.00–1.71; 2 trials), and International Index of Erectile Function-5 scores (MD, 5.38; 95% CI, 4.46–6.29; 2 trials). When acupuncture plus herbal medicine compared with herbal medicine alone, the combination therapy showed significant better improvement in erectile function (RR, 1.68; 95% CI, 1.31–2.15; 7 trials). Only two trials reported facial red and dizziness cases, and needle sticking and pruritus cases in acupuncture group. Conclusions: Low quality evidence shows beneficial effect of acupuncture as adjunctive treatment for people mainly with psychogenic ED. Safety of acupuncture was insufficiently reported. The findings should be confirmed in large, rigorously designed and well-reported trials.

The impacts of LPCVD wrap-around on the performance of n-type tunnel oxide passivated contact c-Si solar cell

Zhou Ying,Tao Ke,Liu Aimin,Rui Jia,Bao Jianhui,Sun Yufeng,Yang Sanchuan,Wang Qinqin,Zhang Qiang,Yang Songbo,Cao Yujia,Qu Hui 한국물리학회 2020 Current Applied Physics Vol.20 No.7

In this paper, Tunnel Oxide Passivated Contact (TOPCon) silicon solar cells with the industrial area (244.32 cm2) are fabricated on N-type silicon substrates. Both the ultra-thin tunnel oxide layer and phosphorus doped polycrystalline silicon (polysilicon) thin film are prepared by the LPCVD system. The wrap-around of polysilicon is observed on the surface of borosilicate glass (BSG). The polysilicon wrap-around can form a leakage current path, thus degrades the shunt resistance of solar cells, and leads to the degradation of solar cell efficiency. Different methods are adopted to treat the polysilicon wrap-around and improve shunt resistance of solar cells. The experimental results indicate that a chemical etching method can effectively solve the problem of polysilicon wrap-around and improve the performance of solar cells. Finally, a conversion efficiency of 22.81% has been achieved by our bifacial TOPCon solar cells, with Voc of 702.6 mV, Jsc of 39.78 mA/cm2 and FF of 81.62%.

PARALLEL IMAGE RECONSTRUCTION FOR NEW VACUUM SOLAR TELESCOPE

Xue-Bao Li,Feng Wang,Yong Yuan Xiang,Yan-Fang Zheng,Ying Bo Liu,Hui Deng,Kai-fan Ji 한국천문학회 2014 Journal of The Korean Astronomical Society Vol.47 No.2

Many advanced ground-based solar telescopes improve the spatial resolution of observation images using an adaptive optics (AO) system. As any AO correction remains only partial, it is necessary to use post-processing image reconstruction techniques such as speckle masking or shift-and-add (SAA) to reconstruct a high-spatial-resolution image from atmospherically degraded solar images. In the New Vacuum Solar Telescope (NVST), the spatial resolution in solar images is improved by frame selection and SAA. In order to overcome the burden of massive speckle data processing, we investigate the possibility of using the speckle reconstruction program in a real-time application at the telescope site. The code has been written in the C programming language and optimized for parallel processing in a multi-processor environment. We analyze the scalability of the code to identify possible bottlenecks, and we conclude that the presented code is capable of being run in real-time reconstruction applications at NVST and future large aperture solar telescopes if care is taken that the multi-processor environment has low latencies between the computation nodes.

Zhao, Bao-Sheng,Liu, Shang-Guo,Wang, Tian-Yun,Ji, Ying-Hua,Qi, Bo,Tao, Yi-Peng,Li, Han-Chen,Wu, Xiang-Nan Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1

Patients at the same pathological stage of esophageal cancer (EC) that received the same surgical therapy by the same surgeon may have distinct prognoses. The current study aimed to explore the possibility of differentially-expressed microRNAs (miRNAs) underlying this phenomenon. Samples were collected from EC patients at the same tumor node metastasis (TNM) stage but with different prognoses. Paracancerous normal tissues were taken as controls. The specimens were histopathologically analyzed. Differentially-expressed miRNAs were analyzed using real-time quantitative reverse transcription polymerase chain reaction. Compared with patients with poor prognosis, those with good prognosis exhibited 88 two-fold or more than two-fold increased miRNA fragments and 4 half-decreased miRNAs. The most noticeably up-regulated miRNAs included hsa-miR-31, hsa-miR-196b, hsa-miR-652, hsa-miR-125a-5p, hsa-miR-146b, hsa-miR-200c, hsa-miR-23b, hsa-miR-29a, hsa-miR-186, hsa-miR-205, hsa-miR-376a, hsa-miR-410, hsa-miR-532-3p, and hsa-miR-598, whereas the most significantly-downregulated miRNAs were hsa-let-7e, hsa-miR-130b, and hsa-miR-103. EC patients at same TNM stage but with different prognoses show differentially-expressed miRNAs.

Lu, Yu,Bao, Jin-Gui,Deng, Yan,Rong, Cheng-Zhi,Liu, Yan-Qiong,Huang, Xiu-Li,Song, Liu-Ying,Li, Shan,Qin, Xue Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.14

Background: The aim of this study was to assess the relationship between IL-18 gene polymorphisms and HBV-related diseases and whether these polymorphisms influence its expression in the Guangxi Zhuang population. Materials and Methods: We enrolled 129 chronic HBV infected (CHB) patients, 86 HBV-related liver cirrhosis (LC) patients and 160 healthy controls in our study. Polymerase chain reaction-restriction fragment length polymorphism methods were used to detect IL-18 gene -607C/A, -137G/C polymorphisms, and an ELISA kit was employed to determine serum IL-18 levels. Results: No correlation was found between the -607C/A polymorphism and risk of HBV-related disease. For the -137G/C polymorphism, the GC genotype and C allele were associated with a significantly lower risk of CHB (95%CI: 0.32-0.95, p=0.034 and 95%CI: 0.35-0.91, p=0.018) and HBV-related LC (95%CI: 0.24-0.89, p=0.022 and 95%CI: 0.28-0.90, p=0.021). A similar decreased risk was also found with the A-607C-137 haplotype. With respect to IL-18 expression, it was significantly lower in both patient groups, but no association was noted between the two polymorphisms in the IL-18 gene and its expression. Conclusions: Our study indicated that the -137C allele in the IL-18 gene may be a protective factor for HBV-related disease, and serum IL-18 level may be inversely associated with CHB and HBV-related LC.

Huang, Xin,Liu, Yan,Zhang, Yong,Li, Shuai-Ping,Yue, Hao,Chen, Chang-Bao,Liu, Shu-Ying The Korean Society of Ginseng 2019 Journal of Ginseng Research Vol.43 No.1

Background: The structural conversions in ginsenosides induced by steaming or heating or acidic condition could improve red ginseng bioactivities significantly. In this paper, the chemical transformations of red American ginseng from fresh Panax quinquefolium L. under steaming were investigated, and the possible mechanisms were discussed. Methods: A method with reversed-phase high-performance liquid chromatography coupled with linear ion trap mass spectrometry ($HPLC-MS^n$)-equipped electrospray ionization ion source was developed for structural analysis and quantitation of ginsenosides in dried and red American ginseng. Results: In total, 59 ginsenosides of protopanaxadiol, protopanaxatriol, oleanane, and ocotillol types were identified in American ginseng before and after steaming process by matching the molecular weight and/or comparing $MS^n$ fragmentation with that of standards and/or known published compounds, and some of them were determined to be disappeared or newly generated under different steaming time and temperature. The specific fragments of each aglycone-type ginsenosides were determined as well as aglycone hydrated and dehydrated ones. The mechanisms were deduced as hydrolysis, hydration, dehydration, and isomerization of neutral and acidic ginsenosides. Furthermore, the relative peak areas of detected compounds were calculated based on peak areas ratio. Conclusion: The multicomponent assessment of American ginseng was conducted by $HPLC-MS^n$. The result is expected to provide possibility for holistic evaluation of the processing procedures of red American ginseng and a scientific basis for the usage of American ginseng in prescription.

Identification of differentially expressed genes from Trichoderma atroviride strain SS003 in the presence of cell wall of Cronartium ribicola

Nai‑Yong Liu,Ze‑Ran Bao,Jing Li,Xin‑Yu Ao,Jia‑Ying Zhu,Yu‑Hui Chen 한국유전학회 2017 Genes & Genomics Vol.39 No.5

The fungal genus Trichoderma has been extensively studied due to its role in the mycoparasitism, and thus developed as biocontrol agent against various plant pathogens. Although the mycoparasitic processes of several Trichoderma species have already been well understood, the information about the mycoparasitic mechanisms of Trichoderma strains resulted from different growth conditions or interacting with different phytopathogens is still limited. In this study, we utilized transcriptome sequencing to identify the differentially expressed genes (DEGs) at 0, 24, 72 and 120 h from T. atroviride strain SS003, growing on an induced-medium with cell walls of Pinus armandii pathogen Cronartium ribicola (CRCW). In total, 86,155,316 reads were obtained with 43,077,658 clean reads. Further, 10,422 genes were identified from four transcriptomes and accounted for 93.89% of annotated genes in T. atroviride IMI 206040 genome, reflecting high-quality sequencing and assembly. In each pairwise comparison, a large number of DEGs were identified with different numbers of genes for up- and down-regulation, respectively. In the presence of CRCW, expression of two main glycoside hydrolase gene families (i.e. chitinase and glucosidase) was induced. Most of 14 secreted enzymes by quantitative real time PCR (qPCR) analysis exhibited a consistent expression pattern with that by RNA-Seq data. This comparative study leads to the identification of phase-specific genes in the interactions of T. atroviride SS003 with C. ribicola, and provides potential molecular targets for improved biocontrol strategies.

Li-na Liu,Guo-ying Zhou,Ai-rong Shen,Bao-ming Shen,Yun Tan,Zhu-ming Tan 한국균학회 2022 Mycobiology Vol.50 No.5

Mycena subpiligera, a new taxon in sect. Fragilipedes that can strongly enhance the germin- ation efficiency of Gastrodia elata seeds, was discovered in subtropical areas of China. As revealed by a morphological comparison with related Mycena species as well as maximum likelihood (ML) and Bayesian phylogenetic analyses based on sequences of the internal tran- scribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA, the new taxon can be distinguished from phenotypically similar and phylogenetically related species. Optimal cultural conditions for M. subpiligera basidiomata are reported, and the germination rate of the new species is compared with that of M. citrinomarginata.
