There are multiple definitions:

1. DNA damage response(English)

   • includes the activation of cell cycle checkpoints, the activation of apoptosis, and the activation of DNA damage tolerance. This last mechanism allows a cell to “accept” DNA damage and continue DNA replication even in the setting of a heightened mutation frequency
   • MRN, DNA, ATM, ATR, DSB, MMR
   • Apoptosis, Genomics

2. discoidin domain receptor(English)

   • receptor tyrosine kinase that recognizes collagens as ligand. They display unique structural features and distinctive activation kinetics, which set them apart from other members of the kinase superfamily. They regulate cell-collagen interactions in normal and pathological conditions and thus are emerging as major sensors of collagen matrices and potential novel therapeutic targets
   • Receptors

3. distal dural ring(English)

   • a conserved intracranial anatomic structure marking the boundary point at which the internal carotid artery (ICA) exits the cavernous sinus (CS) and enters the subarachnoid space
   • CS, ICA
   • Anatomy, Brain (dys)function, Surgery, Microscopy

4. disk displacement with reduction(English)

   • refers to axial condyle morphology and horizontal condylar angle in patients with internal derangement
   • DDN, MRI
   • Medical imaging
