概括
抗氧化剂阿尔法-酸 (ALA) 根据临床前数据显示,它对肌缩性侧面硬化症 (ALS) 是有前途的. 然而,目前缺乏足够的临床证据阻止了批准,需要进一步的研究.
科学领域:
- 生物化学 生化学
- 神经科学是一个神经科学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 阿尔法脂酸 (ALA) 是一种天然存在的脂肪酸,具有抗氧化和抗炎性质.
- ALA作为线粒体能量生产中的辅助因子,表明它可能在神经退行性疾病中发挥作用.
- 在肌缩性侧面硬化症 (ALS) 模型中进行的临床前研究表明,ALA可能会减缓运动衰退并改善生存率.
研究的目的:
- 评估阿尔法-酸 (ALA) 在减缓肌缩侧面硬化症 (ALS) 进展方面的潜在疗效.
- 审查现有证据,包括临床前数据和有限的人类研究,关于ALA对ALS患者的影响.
主要方法:
- 对证明ALA神经保护作用的临床前研究的综述.
- 对事报告和一项涉及ALS患者服用ALA和其他补充剂的小型开放性研究的分析.
- 鉴定缺乏专门针对ALS (PALS) 患者的ALA发表的临床试验.
主要成果:
- 临床前ALS研究表明,ALA减缓了运动功能下降和改善了生存率.
- 事报道和一项小型研究表明,肌肉力量,生活质量,疲劳和情绪都有潜在的益处,但存在混因素.
- 到目前为止,还没有发表任何临床试验,评估ALA在PALS中的疗效.
结论:
- 虽然ALA对ALS表现出可信的机制和临床前前景,但目前的临床数据不足以支持.
- 需要进一步严格的临床试验来确定ALA在减缓ALS进展方面的有效性和安全性.
- 目前的证据不支持使用ALA作为单独治疗ALS.

Amino acids
105.7K
Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

The Citric Acid Cycle
162.4K
The citric acid cycle, also known as the Krebs cycle or TCA cycle, consists of several energy-generating reactions that yield one ATP molecule, three NADH molecules, one FADH2 molecule, and two CO2 molecules.

Polyprotic Acids
32.1K
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Mixtures of Acids
21.9K
The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains two different acids, then its pH can be determined using one of several methods depending upon the relative strength of the acids and their dissociation constants.

Nucleic Acids
50.6K
Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
