Use of Bovine Xenografts for Nasal Defects After Mohs Micrographic Surgery.

Background: Nasal defects after skin cancer excision can often be healed by second intention in certain circumstances.

Objective: We aim to demonstrate the utility of bovine collagen xenografts in supplementing second-intention healing of a variety of nose surgical defects.

Results: Thirty-nine patients underwent Mohs micrographic surgery of the nasal tip (33%), ala (23%), dorsum (31%), sidewall (10%), and root (3%) with the application of bovine collagen xenograft.

IHMCIF: An Extension of the PDBx/mmCIF Data Standard for Integrative Structure Determination Methods.

IHMCIF (github.com/ihmwg/IHMCIF) is a data information framework that supports archiving and disseminating macromolecular structures determined by integrative or hybrid modeling (IHM), and making them Findable, Accessible, Interoperable, and Reusable (FAIR). IHMCIF is an extension of the Protein Data Bank Exchange/macromolecular Crystallographic Information Framework (PDBx/mmCIF) that serves as the framework for the Protein Data Bank (PDB) to archive experimentally determined atomic structures of biological macromolecules and their complexes with one another and small molecule ligands (e.

Revisiting the Anchor Flap for Nasal Defects: How It Fits in the Current Reconstruction Paradigm.

The anchor or Peng flap, first described in 1987, has not been comprehensively discussed in the literature since 2008. The anchor flap is worth revisiting as a useful advancement-rotation flap for medium-sized defects of the distal nose. More recent variations to the flap design incorporate medial cheek advancement and allow for versatility in its use for wide defects of the nasal tip, supratip, and dorsum.
