概括
氧化应激预测了老年人肉症. 下大脑衍生神经营养因子 (BDNF) 和较高的虹膜素水平可能表明具有保护作用,但需要进一步的研究.
科学领域:
- 老年学是指老年学的学科.
- 生物化学 生物化学
- 分子生物学分子生物学
背景情况:
- 虹膜素和来自大脑的神经营养因子 (BDNF) 是潜在的肉类的生物标志物.
- 它们与老年患者氧化应激的关系尚不清楚.
研究的目的:
- 在60岁以上的个体中检查血清里素和BDNF水平.
- 为了检查这些因素之间的关联,dynapenia,和氧化还原平衡.
主要方法:
- 评估了110名老年患者 (平均年龄为78.2岁).
- 测量了血清里素,BDNF,总氧化状态 (TOS) 和总抗氧化状态 (TAS).
- 计算了氧化应激指数 (OSI) 和使用五次坐立测试 (5TSST) 诊断的动力衰竭.
主要成果:
- 负相关性:BDNF与丁纳佩尼亚,虹素和虹素/BDNF比率负相关.
- TOS,TAS和OSI显示了与BDNF的负相关性,以及与虹膜素和激光衰竭的积极相关性.
- 较高的OSI值,年龄较大,女性性别,以及更多的慢性疾病预测了动脉缩症.
结论:
- 反氧失衡是老年患者肉症的独立预测因子.
- 较低的BDNF和较高的虹素/BDNF比率可能表明BDNF对肉类的保护作用.
- 需要进一步的研究来证实这些发现.

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
