Base Excision Repair01:54

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...

Atomic Mass

70.4K
Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

Molar Mass

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

Area of Science:

  • Minimally invasive surgery
  • Surgical oncology
  • Pelvic mass excision

Background:

  • Retrorectal cysts are rare pelvic masses.
  • Large cysts extending superiorly pose surgical challenges.
  • Traditional surgical approaches may be limited.

Observation:

  • A large retrorectal cyst extending to the S3 vertebra was identified.
  • The mass required a minimally invasive surgical solution.
  • Robotic-assisted excision was performed.

Findings:

  • Successful robotic removal of the large retrorectal cyst was achieved.
  • The procedure demonstrated the feasibility of robotic approach for high-seated pelvic masses.
  • The patient tolerated the surgery well.

Implications:

  • Robotic surgery provides a valuable alternative for complex retrorectal cysts.
  • This technique expands treatment options for challenging pelvic masses.
  • Further research into robotic applications for pelvic masses is warranted.
