The effect and mechanism of IL-1 R II / IL-1 RAcp in Autoimmune Myocarditis [PDF]

open access: yes, 2016
【目的】白介素-1(IL-1)是一种T淋巴细胞激活因子,大量研究报道,在心肌炎急性期表达量明显升高。白介素1受体II型(IL-1RII)可以招募白介素1受体辅助蛋白(IL-1RAcp),从而拮抗IL-1β的作用。本课题目的为评估IL-1RII和IL-1RAcp的重组质粒对大鼠自身免疫性心肌炎(EAM)的作用,并进一步探讨其机制,为心肌炎的临床治疗提供理论基础。 【方法】首先在临床实验中,我们选取厦门市心血管病医院诊断明确的心肌炎住院患者28例,应用bio ...

Structure and satisfaction: Social support networks among older grandparents raising adolescent grandchildren

open access: yesJournal of Elder Policy, Volume 4, Issue 1, Page 33-46, April 2025.
Abstract Older custodial grandparents raising adolescent grandchildren are often underprepared to parent adolescent grandchildren with complex biological, psychological, and social needs. Greater understanding of social support networks may contribute to enhancing the well‐being and longevity of these caregivers.

大鼠颅脑外伤后突触素P38在中枢神经系统的表达变化

open access: yesZhongguo shiyan zhenduanxue, 2009
目的观察大鼠颅脑外伤后突触素p38在中枢神经系统表达的变化。方法将SD大鼠分为正常对照组、假手术对照组和损伤组,损伤组用侧位液压冲击法应用不同压力制成颅脑损伤动物模型,于损伤后不同时间点采集标本,采用免疫组织化学技术,检测大鼠损伤灶周边皮层及海马CA1区p38的表达变化,结果采用方差分析和q检验进行统计学分析。结果创伤性颅脑外伤后,损伤灶周边皮层及海马CA1区p38免疫阳性表达增强。结论中枢神经系统损伤后,突触素p38表达增强,且损伤越重,表达增强越明显。

European Biometric Borders and (Im)Mobilities in West Africa: Reflections on Migrant Strategies for Border Circumvention and Subversion

open access: yesPolitics &Policy, Volume 53, Issue 1, February 2025.
ABSTRACT This article argues that the European biometric ID installations and securitization practices at West African borders harm African migrants and compromise the security goals of Europe and Africa. Using Niger's experience, I contend that migrants' poor adaption to the biometric border processes is closely connected to their identity conflicts ...

The effects of Tao-Hong-Si-Wu on hepatic necroinflammatory activity and fibrosis in murine model of chronic liver disease [PDF]

open access: yes, 2016
背景:桃红四物汤原名加味四物汤,载于《医垒元戎》,录自《玉机微义》,是在四物汤的基础上加桃仁、红花而成,是活血养血之代表方。桃红四物汤在临床上应用广泛,诸多研究表明桃红四物汤对多种慢性肝病有一定的治疗作用。慢性肝损伤伴肝纤维化发展过程中存在明显的病理性血管生成与重构,阻碍了肝纤维化的逆转与恢复。通过桃红四物汤对病理性血管生成作用的研究,发现部分活血化瘀中药具有抑制病理性血管生成的作用,抗病理性血管生成可能是活血化瘀药的现代药理作用之一 ...

Research on Eddy Current Testing of Damages in Carbon Fiber Reinforced Polymers [PDF]

open access: yes, 2015
碳纤维增强树脂基复合材料因其优异的性能已被广泛应用于飞行器制造、汽车制造、化学工业、造船与电气设备等各个行业,尤其是在航空航天、船舰以及核能设备等领域受到高度重视。然而,复合材料结构件在制造和使用过程中不可避免的会因为冲击等原因产生各种类型的缺陷。此外,复合材料结构件在损坏之前几乎没有先兆,其破坏具有突然性,这一点往往造成严重的后果。因此对碳纤维增强树脂基复合材料损伤的无损检测研究具有极其重要的意义。 目前应用较多的检测碳纤维增强树脂基复合材料损伤的方法有红外检测、X射线检测以及超声检测等 ...
