Oxidative cleavage of cellulose in the horse gut

Microbial Cell Factories, 2022
Background Lytic polysaccharide monooxygenases (LPMOs) belonging to the auxiliary activity 9 family (AA9) are widely found in aerobic fungi. These enzymes are O2-dependent copper oxidoreductases that catalyze the oxidative cleavage of cellulose. However,

Migration of Oxidized Cellulose to the Ventricle as a Complication of Endoscopic Third Ventriculostomy: A Case Report

Brazilian Neurosurgery, 2018
Endoscopic third ventriculostomy (ETV) is an increasingly common neurosurgical procedure. Hemostatic agentes (porcine gelatin and oxidized cellulose) are normally placed to plug the cortical hole after ETV to avoid cerebral spinal fluid leakage, subdural

Root Compression Due to Swollen Oxidized Regenerated Cellulose after Cervical Disc Surgery

Bagcilar Medical Bulletin, 2016
Oxidized regenerated cellulose is a hemostatic material that is frequently used in neurosurgery. While it is often left in place to avoid postoperative hematoma, in rare cases it may cause neural tissue compression.
