概括
动脉斑块的厚度和狭窄与患有动脉动脉样硬化患者的白质过强度 (WMH) 严重程度有关. 这些发现表明,带斑块的特征可能会影响大脑小血管疾病的进展.
科学领域:
- 神经学 神经学
- 放射学 放射学是指放射学
- 心血管医学 心血管医学
背景情况:
- 白质高强度 (WMH) 是大脑小血管疾病 (CSVD) 的标志物.
- 动脉动脉样硬化是脑血管事件的重要危险因素.
- 状腺斑块特征与WMH之间的关系需要进一步调查.
研究的目的:
- 通过计算机断层扫描血管学 (CTA) 评估的冠状动脉样硬化斑块特征与患有冠状动脉样硬化症的患者的WMH之间的关联.
- 为了确定特定的斑块特征是否预测WMH严重程度.
主要方法:
- 追溯分析180名患有动脉样硬化症的患者,这些患者接受了动脉CTA和脑MRI.
- 使用Fazekas尺度对WMH严重程度进行分级;患者分为没有/轻度和重度WMH组.
- 在CTA上测量的斑块特征 (厚度,长度,狭窄,化);使用人工智能辅助细分量化的WMH体积.
主要成果:
- 与轻微的WMH患者相比,严重的WMH患者的状动脉斑块厚度和狭窄明显增加.
- 在多变量调整后,最大斑块厚度和狭窄度是严重WMH的独立预测因素.

Physical and Chemical Properties of Matter

The characteristics that enable us to distinguish one substance from another are called properties.

Classifying Matter by State
102.9K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

The Atomic Theory of Matter
127.3K
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Characteristics of Life

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

States of Matter
2.8K
Solids, liquids, and gases are the three states of matter commonly found on Earth. A solid is rigid and possesses a definite shape. A liquid flows and takes the shape of its container, except it forms a flat or slightly curved upper surface when acted upon by gravity. Both liquid and solid samples have volumes nearly independent of pressure. A gas takes both the shape and volume of its container.
