Overview of DNA Repair

33.9K
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.

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.

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:

Electrical Current

Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

Summary
This summary is machine-generated.

Current extensor tendon repair practices significantly deviate from established guidelines, with less than half using recommended splinting and early active motion techniques. Strong repair methods for extensor digitorum communis tendons are also underutilized globally.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Traumatology

Background:

  • Extensor tendon injuries require specialized repair techniques.
  • Global standardization of extensor tendon repair is lacking.
  • Real-world surgical practices often differ from established guidelines.

Purpose of the Study:

  • To assess current global practices in extensor tendon repair.
  • To identify discrepancies between recommended guidelines and actual surgical techniques.
  • To inform continuing education and standardization efforts in hand surgery.

Main Methods:

  • An international survey of 50 practicing hand surgeons across America, Asia, and Europe.
  • Multiple-choice questions focused on extensor tendon repair and post-operative therapy.
  • Data collection on splinting, repair techniques, and early motion protocols.

Main Results:

  • Relative motion splinting is underused for boutonniere deformities; static splinting remains prevalent.
  • Strong surgical repair techniques for extensor digitorum communis tendons are less common than recommended.
  • Early active motion protocols are not widely implemented after extensor tendon repair.

Conclusions:

  • Established principles like strong repair and early active motion are not consistently applied to extensor tendons.
  • Current extensor tendon repair practices lag behind expert recommendations.
  • International survey data highlights knowledge and technique deficits, necessitating targeted education.
