CD4+ cells as a potential biomarker for cytomegalovirus retinitis in children with acute lymphocytic leukemia

引用

Chinese Medical Journal 2019年第3期132卷 356-359页

To the Editor: Infection is one of the causes of death after chemotherapy in children with leukemia. About 20% to 30% acute lymphocytic leukemia (ALL) patients die from infection after chemotherapy.[1] Patients with immune deficiency, under chemotherapy, or treated with immunosuppressor are more inclined to be infected with human cytomegalovirus (HCMV) which leads to severe systematic disorders.[2] Cytomegalvirus retinitis (CMVR) is a major sight threatening disease which mainly occurs in patients with immune deficiency and results in blindness if treatment is delayed. The decrease of CD4+ T cells has been related to CMVR in immune deficiency syndrome like AIDS.[3] However, little is known about the relation between the level of T cells with different markers and the onset of CMVR in ALL patients under chemotherapy. Therefore, this study was designed to investigate the diagnostic value of T cells with different markers for cytomegalovirus retinitis after chemotherapy in patients with ALL.

Effects of Ta content on microstructure and oxidation behavior of AlCoCrFeNiYTax high entropy alloy

引用

Rare Metals 2024年第9期43卷 4462-4475页

作者： cang Gu Jun-Hao Hu jian-Bo Song Cheng Xu Ming-Yu Hu Yu-Xuan Zhang jiang Tian Chao Li Jing Feng Faculty of Materials Science and Engineering Kunming University of Science and Technology Department of Physics Hong Kong Baptist University

The oxidation behavior of the Al Co Cr Fe Ni YTaxhigh entropy alloy（HEA） doped with different Ta contents at 1100 °C is investigated. In this study, different reasons for the spallation of the oxide scales of HEAs without/with excessive Ta addition after 1000 h of oxidation are discussed, and the most suitable Ta doping content for this HEA is explored, in which the HEA exhibits both an exceptionally low oxidation rate, and the formation of oxide scales composed of intact a-Al2O3. Meanwhile, it is found that the addition of Ta can effectively inhibit the phase transition of β phase, which makes the surface of the oxide scale smoother. By combining our experimental results with Wagner–Hauffe theory, the influence of Ta drag effect on oxide scale growth is explained, which provides some theoretical guidance for the subsequent design of Al Co Cr Fe Ni HEAs, and can lead to the development of thermal barrier coatings at higher service temperature.
