Bao-Lin Li,Lin-Ling Jiang,Hui-Chun Wang,Zhan-Jun Yang,Xi-Quan Zhang,Hong-Mei Gu,Xian-Hua Tian 대한화학회 2009 Bulletin of the Korean Chemical Society Vol.30 No.7

Two new flavone glycosides, giraldiin A and B, together with three known compounds, annulatin, myricetin 3-O-α-L-rhamnopyranoside and gallic acid, were isolated from the ethanol extract of the root of Pteroxygonum giraldii Damm. et Diels. The structures of giraldiin A and B are designated as 3'-(α-L-arabinopyranosyloxy)-4',5,5',7-tetrahydroxy-3-methoxyflavone and 4'-(β-D-glucopyranosyloxy)-5,5',7-trihydroxy-2',3-dimethoxyflavone, respectively,on the basis of detailed spectroscopic analyses. The free radical scavenging activity of giraldiin A was evaluated by decolouring spectrophotometry of pentamethine cyanine dye (Cy5) with Fe2+-H2O2 Fenton radical generating system. The results indicated the hydroxyl free radical scavenging activity of giraldiin A (ED50 = 23.7 nmol/mL) is higher than that of some known antioxidants such as rutin, puerarin, daidzein and 2,6-di-tertbutyl-4-methylphenol.

Brown tides caused by Aureococcus anophagefferens have occurred frequently in the coastal waters of Qinhuangdao since 2009. The Changli coast is the area most strongly affected by the brown tides, which result in significant economic losses and serious ecological harm. To understand the effects of brown tides on nanoplankton diversity and biomass, samples were collected from May to July in 2012 at station XKK, which is approximately 0.2 nautical miles off the Changli coast. The V9 region of the 18S rDNA gene was used as a marker and was analyzed by Illumina sequencing to assess the nanoplankton diversity and biomass, and real-time fluorescence quantitative PCR was performed to analyze the temporal variations in the copy concentrations of the 18S rDNA of nanoplankton. The results showed that nanoplankton diversity, as determined by the Shannon index, decreased from May to June and increased in July. Illumina sequencing analysis revealed that the plankton community differed among the samples from May to July, and over this period, the dominant phytoplankton groups changed from pelagophytes to chlorophytes. Sufficient nutrients and low grazing pressure by zooplankton and scallops accelerated the growth of small-celled phytoplankton. A. anophagefferens was the most dominant phytoplankton species, with an 18S rDNA maximum copy concentration detected on 26 June, followed by Micromonas sp. and Bathycoccus prasinos, with maximum copy concentrations observed on 3 July. Ciliophora, Arthropoda and Cercozoa were the dominant taxa of the local zooplankton community. The Ciliophora and Arthropoda biomasses decreased, and the Cercozoa biomass increased when the copy concentration of A. anophagefferens peaked on 26 June. We suspect that A. anophagefferens had a significantly negative effect on the growth of Ciliophora and Arthropoda and could be ingested by Cercozoa to promote its proliferation. The small and low-abundance plankton that are likely missed in microscopic and clone library analyses could be detected using Illumina sequencing and qPCR, which provide an effective method for a comprehensive analysis of the plankton community.

Structural, photoluminescent, and dielectric properties of Eu3+-doped Ba0.7Sr0.3TiO3 thin films

Ling Liu,Ni Qin,Dinghua Bao 한국물리학회 2015 Current Applied Physics Vol.15 No.6

Eu3+-doped Ba0.7Sr0.3TiO3 thin films were prepared by a chemical solution deposition method and characterized by X-ray diffraction, field emission scanning electron microscopy, photoluminescence and dielectric measurements. The thin films were well crystallized with a pure perovskite structure. A contraction of the unit cell was observed upon incorporation of Eu3+ ions below 2 mol%, while an expansion occurred as the Eu3+ concentration was further increased above 2 mol%, indicating that Eu3+ ions with different concentrations occupied different lattice sites. Photoluminescence spectra showed two prominent transitions of Eu3+ ions at 594 nm (5D0→7F1) and 618 nm (5D0→7F2) upon excitation at 395 nm (7F0→5L6). There existed two quenching concentrations at 2 mol% and 4 mol% due to different lattice sites of the Eu3+ ions. We also investigated the dielectric properties of the thin films. Our study suggests that Eu3+-doped Ba0.7Sr0.3TiO3 thin films have potential applications in multifunctional optoelectronic devices.

Dopamine D1 receptor (D1DR) and D2 receptor (D2DR) are closely associated with pain modulation, but their exact effects on neuropathic pain and the underlying mechanisms remain to be identified. Our research revealed that intrathecal administration of D1DR and D2DR antagonists inhibited D1–D2DR complex formation and ameliorated mechanical and thermal hypersensitivity in chronic constriction injury (CCI) rats. The D1–D2DR complex was formed in the rat spinal cord, and the antinociceptive effects of D1DR and D2DR antagonists could be reversed by D1DR, D2DR, and D1–D2DR agonists. Gαq, PLC, and IP3 inhibitors also alleviated CCI-induced neuropathic pain. D1DR, D2DR, and D1–D2DR complex agonists all increased the intracellular calcium concentration in primary cultured spinal neurons, and this increase could be reversed by D1DR, D2DR antagonists and Gαq, IP3, PLC inhibitors. D1DR and D2DR antagonists significantly reduced the expression of p-PKC γ, p-CaMKII, p-CREB, and p-MAPKs. Levo -corydalmine ( l -CDL), a monomeric compound in Corydalis yanhusuo W.T. Wang, was found to obviously suppress the formation of the spinal D1–D2DR complex to alleviate neuropathic pain in CCI rats and to decrease the intracellular calcium concentration in spinal neurons. l- CDL-induced inhibition of p-PKC γ, p-MAPKs, p-CREB, and p-CaMKII was also reversed by D1DR, D2DR, and D1–D2DR complex agonists. In conclusion, these results indicate that D1DR and D2DR form a complex and in turn couple with the Gαq protein to increase neuronal excitability via PKC γ, CaMKII, MAPK, and CREB signaling in the spinal cords of CCI rats; thus, they may serve as potential drug targets for neuropathic pain therapy.

Ling Sun,Li Tang,Xiao-di Bao,Wei Liu 보안공학연구지원센터 2016 International Journal of Smart Home Vol.10 No.10

Based on the Shanghai cruise industry research, this cruise industry chain has problems with balance. Game theory was used and imbalance mainly due to lack of shipbuilding enterprises and proprietary cruises, and also because foreign cruise companies dominate Shanghai cruise industry chain. Learning from the successful experience of foreign cruise homeports’ development, the paper considers transferring the chain’s dominant right to the port enterprise gradually. Using Shapley Model to solve benefits distribution of cruise industry chain dominated by port companies. The profits distribution ratio of cruise companies, port companies and service supporting enterprises is13/48:47/96:23/96. Nash Model was also used to study the benefits distribution of industry chain whose member companies are equal. Modeling results show that Shapley Model corresponds with the requirements of benefit maximization. Finally, a validation analysis was done and proved that only the cruise industry chain leaded by homeport that can maximize the economic benefits.

Su, Ling-Yan,Li, Xue-Lian,Shen, Li,Zhang, Yue,Zhao, Meng-Meng,Yin, Zhi-Hua,Su, Hong-Ying,Zhou, Bao-Sen Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19

Background: Telomerase reverse transcriptase (TERT) and cleft lip and palate trans-membrane 1 like (CLPTM1L) genes located on chromosome 5p15.33 are known to influence the susceptibility to various cancers. Here, we examined the association of TERT and CLPTM1L single nucleotide polymorphisms (SNPs) with hepatocellular carcinoma (HCC). Materials and Methods: Genotyping of TERT SNP rs2736098 and CLPTM1L SNP rs401681 was performed using TaqMan allelic discrimination assays in a case-control study of 201 HCC cases and 210 controls in a Chinese male population. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression analyses. Results: Both the rs2736098 T allele of TERT and the rs401681 T allele of CLPTM1L were associated with a significantly increased risk of HCC (adjusted odds ratio [OR]=1.605, 95% confidence interval [CI]=1.164-2.213; adjusted OR=1.399, 95%CI=1.002-1.955, respectively). Individuals carrying both TERT and CLPTM1L risk genotypes had an even higher risk of HCC (adjusted OR=4.420, 95%CI= 2.319-8.425). The TERT rs2736098 T allele was also significantly associated with the level of the HCC clinical indicator alpha-fetoprotein (P=0.026). Conclusions: Our results show that genetic variants of TERT and CLPTM1L may contribute to HCC susceptibility in Chinese males.
