Laser-enhanced thermal effect of moderate intensity focused ultrasound on bio-tissues

引用

Science China(Physics,Mechanics & Astronomy) 2017年第9期60卷 28-36页

作者： JinYu zhao ShuYi Zhang XiuJi shui Li Fan Laboratory of Modern Acoustics Institute of Acoustics Collaborative Innovation Center of Advanced Microstructures Nanjing University

For avoiding extra-damage to healthy tissues surrounding the focal point during high intensity focused ultrasound(HIFU) treatment in medical therapy, to reduce the ultrasonic intensity outside the focal point is expected. Thus, the heating processes induced by moderate intensity focused ultrasound(MIFU) and enhanced by combined irradiation of laser pulses for bio-tissues are studied in details. For fresh bio-tissues, the enhanced thermal effects by pulsed laser combined with MIFU irradiation are observed experimentally. To explore the mechanisms of these effects, several tissue-mimicking materials composed of agar mixed with graphite powders are prepared and studied for comparison, but the laser-enhanced thermal effects in these mimicking materials are much less than that in the fresh bio-tissues. Therefore, it is suggested that the laser-enhanced thermal effects may be mainly attributed to bio-activities and related photo-bio-chemical effects of fresh tissues.

Influence of coronal holes on CMEs in causing SEP events

Research in Astronomy and Astrophysics 2010年第10期10卷 1049-1060页

W. Hansen Experimental Physics Laboratory Stanford University Stanford CA 94305 USA

The issue of the influence of coronal holes （CHs） on coronal mass ejections （CMEs） in causing solar energetic particle （SEP） events is revisited. It is a continuation and extension of our previous work, in which no evident effects of CHs on CMEs in generating SEPs were found by statistically investigating 56 CME events. This result is consistent with the conclusion obtained by Kahler in 2004. We extrapolate the coronal magnetic field, define CHs as the regions consisting of only open magnetic field lines and perform a similar analysis on this issue for 76 events in total by extending the study interval to the end of 2008. Three key parameters, CH proximity, CH area and CH relative position, are involved in the analysis. The new result confirms the previous conclusion that CHs did not show any evident effect on CMEs in causing SEP events.

T cell infiltration is associated with kidney injury in patients with anti-glomerular basement membrane disease

引用

Science China(Life Sciences) 2016年第12期59卷 1282-1289页

作者： shui-Yi Hu Xiao-Yu Jia Jian-Nan Li Xin Zheng Jie Ao Gang Liu zhao Cui ming-Hui zhao Renal Division Department of Medicine Peking University First HospitalInstitute of Nephrology Peking UniversityKey Laboratory of Renal Disease Ministry of Health of China Key Laboratory of CKD Prevention and Treatment Ministry of Education of China Beijing 100034 China Peking-Tsinghua Center for Life Sciences Beijing 100871 China Department of Nephrology Tianjin Medical University General Hospital Tianjin 300052 China

Cell-mediated autoimmunity, particularly that involving autoreactive T cells, participates in mediating anti-glomerular basement membrane(GBM) disease. However, direct kidney injury mediated by renal infiltrated T cells has not been clearly elucidated in humans. The T cell profile(CD3, CD4, CD8, IL-17, and foxp3) and macrophage(CD68) were examined by immunohistochemistry on renal biopsy tissues from 13 patients with anti-GBM disease. The correlation between cell infiltration and clinical data was also analyzed. We found that the distribution of T cell infiltration was predominant in the peri-glomerular and interstitial areas. CD3^+ T cell infiltratrion around the glomeruli with cellular crescent formations was significantly higher than that around the glomeruli with mild mesangial proliferation. CD8^+ T cells significantly accumulated around the glomeruli with cellular crescents without Ig G deposits compared to those with Ig G deposits. The prevalence of infiltrating CD8^+ T cells was correlated with the percentage of ruptured Bowman's capsules. In conclusion, cellular immunity may play a crucial role in the inflammatory kidney injury in anti-GBM patients. The periglomerular infiltration of T cells, especially CD8^+ T cells, may participate in the pathogenic mechanism of glomerular damage.

Zn^(2+)依赖型组蛋白去乙酰化酶在植物非生物胁迫响应中的作用及机制

生物工程学报 2025年第2期41卷 491-509页

作者：魏明赵萌吴欣蕊伍国强兰州理工大学生命科学与工程学院甘肃兰州730050

Zn^(2+)依赖型组蛋白去乙酰化酶(Zn^(2+)-dependent histone deacetylases,HDAs)是一类与酵母还原性钾依赖型3(reduced potassium dependency 3,RPD3)高度同源的去乙酰化酶蛋白家族。HDAs通过去除组蛋白和非组蛋白赖氨酸残基上的乙酰基而广泛调控染色体稳定、基因转录和蛋白质活性。在植物中,HDAs介导的去乙酰化修饰在植物生长发育和非生物胁迫响应中发挥重要作用。本文综述了植物HDAs的发现、结构与分类、去乙酰化机制,重点总结了该蛋白家族在植物非生物胁迫中的调控作用,并对未来研究方向进行展望,为HDAs介导的表观遗传学研究提供了理论支持。

本研究利用从普洱茶中分离的汉逊德巴利酵母(Debaryomyces hansenii)PETY002接种强化发酵普洱茶(EF组)。结果表明,EF组的酵母菌落总数显著高于传统发酵(NF组)。感官审评发现,EF组茶汤颜色更深、滋味更醇厚、香气带有菌香。特征成分测定结果表明,与NF组相比,EF组的茶褐素和水浸出物的含量增加,而茶多酚、儿茶素类(儿茶素、表没食子儿茶素、没食子儿茶素、表没食子儿茶素没食子酸酯)以及咖啡碱的含量降低,黄酮组分和氨基酸组分差异较小。微生物群落分析表明,汉逊德巴利酵母是EF组中的优势真菌,德巴利酵母属(Debaryomyces)与嗜热真菌属(Thermomyces)存在相互竞争的关系。相关性分析表明,德巴利酵母属与茶褐素呈显著正相关,与可溶性糖和茶黄素呈显著负相关。综上,接种汉逊德巴利酵母强化发酵改变了发酵微生物群落的多样性和组成,通过与其他优势微生物相互作用提高了普洱茶的品质。
