概括
三糖与高密度脂蛋白胆固醇 (TG/HDL) 比例的长期平均值,这是一种失脂症的标志物,与大脑动脉动脉样硬化有关. 脂质水平的变化没有显示出与CIMT.的独立关联.
科学领域:
- 心血管医学 心血管医学
- 脂质代谢 脂质代谢是什么
- 动脉样硬化研究 动脉样硬化研究
背景情况:
- 甘油三和高密度脂蛋白胆固醇 (TG/HDL) 的比率是动脉动脉脂缺血和胰岛素抵抗的一个关键指标.
- 虽然其与亚临床动脉样硬化病的联系已知,但长期TG/HDL负担与其在 carotid intima-media厚度 (CIMT) 上的时间变异性之间的独特作用需要澄清.
研究的目的:
- 调查TG/HDL比率和CIMT的纵向平均值和时间变化之间的差异关联.
- 要确定TG/HDL的变化是否会改变平均TG/HDL比率和CIMT之间的关系.
主要方法:
- 对260名成年患者进行了回顾性分析,他们至少进行了三年的脂质测量和动脉超声学.
- 计算纵向平均TG/HDL比率和各种变化指数 (SD,CV,ARV,VIM).
- 使用相关性,多变量回归,联合类别和分层分析评估相关性,包括他类药物治疗相互作用.
主要成果:
- 纵向平均TG/HDL比率独立地与增加的CIMT相关,即使在调整心血管风险因素后也是如此.
- TG/HDL变化指数没有显示出与CIMT的独立关联,也没有改善预测模型超出平均比率.
- 平均TG/HDL升高与高CIMT相关,不论其变异性如何,观察到非线性,依赖于值的关系.
结论:
- 由长期平均TG/HDL比率显示的,累积暴露于动脉动脉脂缺血症,是亚临床性动脉动脉样硬化的更强的决定因素,而不是短期的脂质波动.
- TG/HDL变异性和他类药物治疗之间的显著相互作用表明,治疗可能会调节脂质变异性的影响.

Variability: Analysis
504
Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

Random Variables
17.8K
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Long-term Depression
33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Graphs of Equations in Two Variables
234
An equation with two variables, typically written in the form y = f(x) or Ax + By = C, describes a relationship between quantities represented by x and y. Each solution to such an equation is an ordered pair (x, y) that satisfies the equation when substituted. These pairs can be represented graphically to understand the variables' relationship visually.A common technique for constructing the graph of a two-variable equation is to create a value table. Begin by choosing several values for the...

Variables Affecting Phosphorescence and Fluorescence
1.5K
Fluorescence and phosphorescence are essential phenomena in fields like analytical chemistry, biological imaging, and materials science, where they detect molecular properties and visualize cellular structures. Understanding the variables that influence these luminescent behaviors is crucial for maximizing accuracy and efficiency in their applications. These variables can broadly be grouped into chemical structure, solvent properties, and external conditions, each playing a distinct role in...

Work and Energy for Variable Forces
5.8K
When an object is acted upon by a variable force, the amount of work done and the change in energy of the object can be more complex to calculate compared to when a constant force is applied. Work is the product of force and displacement, while energy is the capacity of a system to do work. When a constant force is applied to an object, the work done can be calculated as the product of the force and the distance moved in the direction of the force. However, when a variable force is applied, the...
