Base Excision Repair

26.4K
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.
The first step of...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

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:

Overview of DNA Repair

In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Summary

Postoperative arachnoid cysts can cause significant symptoms. Surgical intervention, including excision or fenestration, is the standard treatment for these rare complications.

Area of Science:

  • Neurosurgery
  • Spinal Surgery

Background:

  • Arachnoid cysts are rare complications following spinal surgery.
  • These cysts can lead to debilitating symptoms such as back pain, radiculopathy, and cauda equina syndrome.

Purpose of the Study:

  • To review the surgical management of symptomatic postoperative arachnoid cysts.
  • To discuss preferred surgical techniques and potential complications.

Main Methods:

  • Review of literature on postoperative arachnoid cysts.
  • Discussion of surgical options: cyst excision and cyst fenestration.
  • Consideration of intraoperative and postoperative management strategies.

Main Results:

  • Surgical management is indicated for symptomatic cases.
  • Cyst excision is the preferred method, but fenestration may be suitable for adherent cysts.
  • Potential complications include dural defects requiring grafting and cerebrospinal fluid diversion via lumbar drains.

Conclusions:

  • Prompt surgical intervention is crucial for managing symptomatic postoperative arachnoid cysts.
  • Surgical technique should be tailored to cyst characteristics, balancing efficacy with morbidity.
  • Awareness and preparedness for potential complications are essential for optimal patient outcomes.
