ARTHROSCOPIC ANATOMIC HUMERAL HEAD RECONSTRUCTION WITH OSTEOCHONDRAL ALLOGRAFT TRANSPLANTATION FOR LARGE HILL-SACHS LESIONS

Arthroscopic Anatomic Humeral Head Reconstruction With Osteochondral Allograft Transplantation for Large Hill-Sachs Lesions

Anatomic reconstruction of the humeral head with osteochondral allograft has been reported as a solution for large Hill-Sachs lesions with or without glenoid bone loss.However, to date, varying techniques have been used.This technical note describes an arthroscopic reconstruction technique using fresh-frozen, side- and size-matched osteochondral hu

DNA damage triggers genetic exchange in Helicobacter pylori.

Many organisms respond to DNA damage by inducing expression of DNA repair genes.We find that the human stomach pathogen Helicobacter pylori instead induces transcription and translation of natural competence genes, thus increasing transformation frequency.Transcription of a lysozyme-like protein that promotes DNA donation from intact cells is also
