我们都不同:模拟生理系统中的关键个体差异
1Department of Applied Mathematics, Department of Biology, Cheriton School of Computer Science, School of Pharmacology, University of Waterloo, Waterloo, Ontario N2L 3G1, Canada.
目前的全身生理模型经常使用单一的基线,无法代表多样化的群体. 结合性别,年龄,体重和一天中的时间,可以提高个体健康模拟模型的准确性.
科学领域:
- 生理学建模 生理学建模
- 系统生物学 系统生物学
- 计算生理学计算生理学
背景情况:
- 人类整合系统的数学模型对于理解生理调节至关重要.
- 现有的模型通常使用70公斤的基线,35岁的男性,限制了概括性.
- 性,年龄,体重和一天中的时间等因素显著影响生理功能.
研究的目的:
- 突出目前通用生理学模型的局限性.
- 倡导将个人特异性因素 (性别,年龄,体重,一天的时间) 纳入全身模型.
- 为了证明个性化生理模拟对于准确表示的必要性.
主要方法:
- 审查和分析现有的全身动态模型.
- 确定关键的生理调节器:性别,年龄,体重和昼夜节律.
- 使用血压调节系统的说明性示例.
主要成果:
- 一般模型无法准确地代表多样化的群体 (女性,老年人,不同体重).
- 性,年龄,体重和一天中的时间是生理反应的关键决定因素.
- 个性化模型对于捕捉生理系统中的个体变异性至关重要.
结论:
- 生理系统的数学模型必须整合个体特征以提高准确性.
- 开发特定于性别,年龄,体重和时间的模型对于推进个性化医学至关重要.
- 血压调节系统是证明这些个体差异的影响的一个关键例子.

Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...
