Base Excision Repair01:54

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

概括

这项研究回顾了远距离二头肌肌修复的单皮节按技术,表明它提供了与双皮节按相当的强度,具有降低神经损伤风险等潜在好处. 这种方法提供了一种安全有效的选择,可以恢复肘部曲和俯卧强度.

科学领域:

  • 整形外科手术 整形外科手术
  • 运动医学 运动医学
  • 肌肉骨研究 研究

背景情况:

  • 远距离双肩肌破裂通常影响中年男性,导致肘部曲 (30%) 和俯卧 (40%) 强度的显著损失.
  • 手术修复适用于完全破裂或部分撕裂失败的保守治疗,旨在恢复功能.
  • 存在各种固定方法,包括双皮质按,横骨道,接和干扰螺丝.

研究的目的:

  • 通过使用单角扣固定方法来审查远距离二头肌肌修复的技术和结果.
  • 为了比较单皮质按固定的有效性和安全性与其他已知技术.

主要方法:

  • 采用单一切口技术,使用距离肘部曲的横切口.
  • 远距离二头肌肌与放射性结核形成的接固定是用单角皮按实现的.
  • 手术后的治疗方案取决于外科医生,但与肌修复的标准实践保持一致.

主要成果:

  • 远距离双肩肌破裂的初级修复产生了有希望的结果,患者报告和客观结果良好到优秀.
  • 单角按固定显示了与双角按固定相比,在统计学上相当的循环负载和负载到故障值.
  • 这种等价性表明,这种强度与双皮质按的强度相当,而双皮质按已知比其他方法更为硬.
