概括
这项研究发现,患有二次 amenorrhea 的女性,包括功能性下丘脑 amenorrhea (FHA) 和初级卵巢缺陷 (POI),表现出类似的类固醇特征. 然而,POI患者的皮质类固醇水平较低,FHA患者没有表现出高皮质素血症.
科学领域:
- 内分泌学 在内分泌学.
- 生殖医学 生殖医学
- 代谢学 代谢学 代谢学
背景情况:
- 二次性缺血,一种影响月经功能的疾病,可以源于功能性下丘脑缺血 (FHA) 或初级卵巢缺陷 (POI).
- 代谢学研究在妇科中越来越重要,用于诊断和治疗监测.
- 由于压力和能量缺乏,预计FHA中皮质醇会升高,这可能会影响月经功能.
研究的目的:
- 为了比较患有二次 amenorrhea (FHA,POI) 的女性与健康对照者的多成分血型类固醇.
- 通过高性能液体染色学与双重质谱学 (HPLC-MS/MS) 结合,识别特定的类固醇变异.
主要方法:
- 这是一项涉及120名患有二次 amenorrhea (FHA,POI) 的妇女和34名健康对照 (18-39岁) 的横截面研究.
- 使用HPLC-MS/MS分析了血液中的类固醇 (androstenedione,corticosterone,testosterone,cortisol,cortisone,DHEA) 的情况.
主要成果:
- 分析了154名妇女的情况. 原发性卵巢缺陷 (POI) 组表现出显著较低的皮质水平 (p<0.0001).
- 没有发现皮质醇,皮质素或脱水氨 (DHEA) 的显著差异在异常症组和对照组之间.
- 在任何参与者身上都没有检测到高皮质素血症.
结论:
- 在二次 amenorrhea 患者中,血液中的类固醇概况显示出不同病因的共同特征,表明共享的潜在机制.
- 在POI患者中观察到皮质类固醇的显著下降.
- 功能性下丘脑缺血 (FHA) 缺少高皮质素血症需要进一步调查.

Secondary Active Transport
138.0K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
637
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...

Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...
