- 心血管医学 心血管医学
- 生物化学 生物化学
背景情况:
- 脱脂症是与慢性炎症相关的关键心血管风险因素.
- 白血球衍生的炎症标志物在脱脂症中被研究,但乙氨基酸标志物较少被探索.
- 氨基酸与淋巴细胞比率 (ELR) 和氨基酸调整的全身炎症反应指数 (EA-SIRI) 是新的标志物.
研究的目的:
- 调查不同类型的失脂症表型中与乙氨基酸相关的炎症标志物ELR和EA-SIRI.
- 为了确定ELR,EA-SIRI和脂质资料之间的关联.
- 评估ELR和EA-SIRI在识别动脉脂障碍症方面的潜力.

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Lipid-derived Compounds in the Human Body
6.3K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Atherosclerosis I: Introduction
923
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Asymmetric Lipid Bilayer
9.6K
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...
