纳米技术纳米技术

背景情况:

早期牙质病变 (EECLs) 构成一个重大的牙科挑战.
目前的处理方法,如5%的NaF漆,在重矿化深度上有局限性.
需要新的生物材料来增强质复矿效率.

研究的目的:

为了比较自我组装 (P11-4,P26) 和富含白氨酸的氨基蛋白 (LRAP) 与5%的NaF漆的重矿化潜力.
评估这些药物对人类牙面膜中人造EECL的疗效.
评估对质矿物密度,硬度和弹性模量的影响.

主要方法:

人工EECL是使用去矿化溶液创建的.
乳样本经历了8天的pH循环.
微计算机断层扫描和纳米机械测试评估了矿物质密度,硬度和弹性模量.

主要成果:

在P26和P11-4SAP中,平均矿物密度增长率最高.
在用P11-4和P26处理的EECL的外层和内层观察到增强的硬度和弹性模量.
这些发现表明,在病变的更深处,透和再生矿物质的程度更高.

结论:

P26和P11-4SAPs在EECL深度的重矿化方面表现出比5%的NaF漆更大的有效性.
SAPs代表了治疗早期牙损的有希望的替代方案.
对SAP的进一步研究可能会导致先进的牙科修复材料.

Peptide Bonds

Peptide Bonds

A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...
