概括
肝炎C病毒 (HCV) 治愈艾滋病毒 (PWH) 感染者并不能保证肝脏完全恢复,因为与氨基酸代谢相关的显著的血miRNA特征在治疗后持续一年,需要长期监测.
科学领域:
- 肝病学和病毒学.
- 人类免疫缺陷病毒 (HIV) 研究研究
- 分子生物学和代谢学
背景情况:
- 在成功治疗型肝炎病毒 (HCV) 之后,持续的肝病理是一个临床问题,特别是在与HCV共感染的HIV (PWH) 患者中.
- 患有HCV共感染的PWH患有加速肝病进展的风险更高,即使在达到持续病毒学反应 (SVR) 后也是如此.
研究的目的:
- 在完成HCV治疗一年后,在患有肝硬化的PWH患者中表征血微RNA (miRNA) 概况.
- 在这个人群中调查血miRNA变化和代谢物变化之间的关系.
- 评估HCV治愈是否导致PWH肝硬化患者的肝脏完全恢复.
主要方法:
- 对47名获得HCV清除的PWH进行横截面研究.
- 在HCV治疗后一年收集的血样本,通过肝硬度测量 (LSM) 分为补偿性肝硬化 (n=32) 和非肝硬化 (n=15) 组.
- 用于miRNA分析的小RNA测序和用于代谢学的非向毛细体电泳质谱 (CE-MS);统计分析包括通用线性模型 (GLM) 和斯皮尔曼相关性.
主要成果:
- 与非肝硬化组相比,肝硬化组中发现了15个显著差异表达 (SDE) miRNA (9个上调,6个下调) 的独特特征.
- 途径丰富分析表明,这些SDE小RNA可能调节参与免疫反应和氨基酸代谢的基因.
- 相关性分析显示了特定的SDEmiRNA和血氨基酸之间的显著关联;上调的miRNA与L-氨酸正相关,而下调的miRNA与L-三相反相关.
结论:
- 经过HCV共感染史的PWH肝炎患者在完成HCV治疗一年后表现出与失调的氨基酸代谢相关的独特的血miRNA特征.
- 在这个人群中,HCV治愈并不等同于肝脏完全恢复.
- 长期监测对于PWH与HCV共感染和肝硬化由于持续的肝病理和代谢变化至关重要.

Ecological Succession
21.5K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Curing of Concrete
369
The hydration of cement takes place within the water-filled capillary pores. However, environmental elements can disrupt this process by evaporating water from the concrete surfaces. Sealed concrete with a water-cement ratio below 0.5 experiences self-desiccation, leading to water loss. The water loss in concrete is mitigated by curing. This technique involves keeping the concrete saturated to maintain the necessary temperature and moisture conditions, to optimally fill the spaces in the cement...

Curing Methods
293
Concrete members with a small surface-to-volume ratio are cured by oiling and moistening the forms before casting the concrete member. These forms can be left in place for a prolonged period to prevent moisture loss, and can be wetted if made of a material suitable for wetting. If the forms are removed early, the concrete member is moistened and covered with polythene sheets to maintain moisture. For large horizontal concrete surfaces exposed to dry weather, a temporary covering is suspended...

Accelerated Curing of Concrete
472
Accelerating concrete curing is achieved by applying heat and additional moisture. This process accelerates the hydration of the cement, resulting in an earlier strength gain in the concrete. Steam curing is a method wherein the concrete products are either transported through a chamber on a conveyor belt or encased in plastic, allowing steam at atmospheric pressure to circulate freely around them. This process begins with a phase of moist curing that typically lasts between 3 to 5 hours, after...

Composition of Blood Plasma
8.4K
Blood plasma is a fluid that contains approximately 92% water and 8% solutes. The solutes include various types of proteins, which constitute about 7% of the total solutes in the plasma. The high-molecular-weight proteins—albumins, globulins, and fibrinogen—are essential to plasma function. Albumins, making up about 60% of the plasma proteins, maintain the osmotic balance within blood vessels by preventing excessive water leakage. Additionally, albumins serve as carrier proteins,...

MicroRNAs
24.2K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...
