- 生物材料工程 生物材料工程
背景情况:
- 大量填充树脂基复合材料 (RBC) 具有临床优势,但其处理方式可能会受到温度的影响.
- 预热RBC是一种提高粘度和处理能力的技术,但必须仔细监测温度变化.
研究的目的:
- 在使用三个不同的加热装置 (Phasor,VisCalor,Compex HD) 加热时,评估两个散装RBC (VisCalor散装和Filtek One散装填充恢复) 的温度变化.
- 为了评估加热枪和RBC类型在模拟的II类空洞中插入和光固化期间对温度的影响.
主要方法:
- 在RBC插入和光固化过程中,使用热摄像头测量温度变化.
- 使用Phasor,VisCalor和Compex HD设备加热红细胞.
- 用重复测量ANOVA和t测试分析了数据.
主要成果:
- 配有Filtek One批量填充恢复 (OBF) 的Compex HD设备导致脉地板温度上升的最低值 (2.7°C).
- 带有VisCalor Bulk (VBF) 的Phasor装置显示了最大的脉地板温度上升 (8.8°C).
- 使用Phasor加热的OBF达到48.6°C的最高温度;Compex HD保持着稳定的峰值温度,与Phasor和Viscalor不同.
结论:
- 加热枪和RBC类型的组合在临床使用期间显著影响温度的发展.
- 了解这些温度变化对于优化红细胞处理和潜在影响临床结果至关重要.

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

01:16Thermal Sigmatropic Reactions: Overview
Sigmatropic rearrangements are a class of pericyclic reactions in which a σ bond migrates from one part of a π system to another. These are intramolecular rearrangements where the total number of σ and π bonds remain unchanged.
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in 1,5-hexadiene, referred to as...
