| 1 | Photoluminescence properties and thermal stability of Eu^(3+)-activated La_(7)Ta_(3)W_(4)O_(30) red-emitting phosphors for near-UV-excited w-LEDs显示文摘Novel trivalent europium(Eu^(3+))-activated La_(7)Ta_(3)W_(4)O_(30):xEu^(3+)(x=0.5 mol%-40 mol%) red-emitting phosphors were synthesized by means of a high-temperature solid-state reaction.The structure,morphology,photoluminescence,thermal-stability properties,lifetime,and color-rendering of the prepared phosphors were investigated in detail.The La_(7)Ta_(3)W_(4)O_(30):Eu^(3+) phosphors show five emission peaks under near-ultraviolet(n-UV) at 397 nm,and these peaks are ascribed to the transitions of ^(5)D0-^(7)Fj(j=0,1,2,3 and 4) by Eu^(3+) ions.The optimal doping concentration of Eu^(3+) is 20 mol%,and the critical distance of the energy transfer between the Eu^(3+)ions was calculated to be 1.768 nm.The quenching temperature(T_(0.5)) of La_(7)Ta_(3)W_(4)O_(30):20 mol%Eu^(3+) is about 440 K.The quantum yield(QY) was measured to be 85.85%.The fabricated white-light-emitting diodes(w-LEDs) possess high color-rendering index(R_(a)) of 90,and high correlated color temperature(CCT) of 5810 K,respectively.The Commission Internationale de L’Eclairage(CIE) coordinates are(0.311,0.322).Therefore,the prepared phosphor has a promising application for w-LEDs. | Yu Ren Bin Deng Ting Liang Shuang Shu Junlan Guo Shoucheng Zhao Ruijin Yu | 2021 | Journal of Rare Earths2021，39，8： | 1 |

| 5 | Dihydroartemisinin increased the abundance of Akkermansia muciniphila by YAP1 depression that sensitizes hepatocellular carcinoma to anti-PD-1 immunotherapy显示文摘The effect of anti-programmed cell death 1(anti-PD-1)immunotherapy is limited in patients with hepatocellular carcinoma(HCC).Yes-associated protein 1(YAP1)expression increased in liver tumor cells in early HCC,and Akkermansia muciniphila abundance decreased in the colon.The response to anti-PD-1 treatment is associated with A.muciniphila abundance in many tumors.However,the interaction between A.muciniphila abundance and YAP1 expression remains unclear in HCC.Here,anti-PD-1 treatment decreased A.muciniphila abundance in the colon,but increased YAP1 expression in the tumor cells by mice with liver tumors in situ.Mechanistically,hepatocyte-specific Yap1 knockout(Yap1^(LKO))maintained bile acid homeostasis in the liver,resulting in an increased abundance of A.muciniphila in the colon.Yap1 knockout enhanced anti-PD-1 efficacy.Therefore,YAP1 inhibition is a potential target for increasing A.muciniphila abundance to promote anti-PD-1 efficacy in liver tumors.Dihydroartemisinin(DHA),acting as YAP1 inhibitor,increased A.muciniphila abundance to sensitize anti-PD-1 therapy.A.muciniphila by gavage increased the number and activation of CD8^(+)T cells in liver tumor niches during DHA treatment or combination with anti-PD-1.Our findings suggested that the combination anti-PD-1 with DHA is an effective strategy for liver tumor treatment. | Zhiqin Zhang Xinli Shi Jingmin Ji Yinglin Guo Qing Peng Liyuan Hao Yu Xue Yiwei Liu Caige Li Junlan Lu Kun Yu | 2023 | Frontiers of Medicine2023，17，4： | 0 |
