概括
之前的轻度创伤性脑损伤 (mTBI) 史影响低水平爆炸 (LLB) 暴露后的生物标志物变化. 具有mTBI病史的军人表现出与炎症相关的基因表达变化和爆炸后的粉样β清除.
科学领域:
- 神经科学是一个神经科学.
- 生物标志物 生物标志物
- 军人卫生保健 军人卫生保健
背景情况:
- 爆炸伤害是服务人员 (SM) 的担忧.
- 反复暴露于爆炸会导致类似脑震荡的症状和神经认知缺陷.
- 之前轻度创伤性脑损伤 (mTBI) 对低级爆炸 (LLB) 的反应的影响尚不清楚.
研究的目的:
- 调查之前的mTBI历史如何影响LLB暴露后的生物标志物变化.
- 识别对LLB生物标志物反应的个体间差异.
主要方法:
- 测试的基因转录和血中的粉样β (Aβ) 蛋白水平来自30个SMs.
- 在爆发前,爆发后1小时,爆发后16小时收集血液样本.
- 使用RNA-seq,SIMOA和统计模型,根据年龄和mTBI状态进行调整.
主要成果:
- 参与血脑屏障,炎症和免疫反应的基因的高表达在MSS与mTBI历史.
- 根据爆炸后立即发生的mTBI史,Aβ40和Aβ42水平没有差异.
- 爆发后16小时降低了Aβ40和Aβ42水平,在mTBI的MS中增加了粉样β调节基因的表达.
结论:
- 爆炸暴露后生物标志物水平的个体间差异受先前mTBI历史的影响.
- 之前的mTBI可能会改变随后的低水平爆炸暴露的炎症和粉样β反应.

Traumatic Memory
651
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Post-traumatic Stress Disorder
711
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...
