Influence of monomer concentration on the morphology, contact angle, water uptake, and antibacterial activity of grafted cellulose obtained from peel durian

open access: yesJurnal Natural, 2022
The objective of the current study is to evaluate and determine the effect of monomer concentration of ClAETA on the grafting copolymerization of oxidized cellulose which isolated from peel durian. Four concentrations of ClAETA were used in this study, e.

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

open access: yesBagcilar 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.

Oxidized (non)-regenerated cellulose affects fundamental cellular processes of wound healing. [PDF]

open access: yes, 2016
In this study we investigated how hemostats such as oxidized regenerated cellulose (ORC, TABOTAMP) and oxidized non-regenerated cellulose (ONRC, RESORBA CELL) influence local cellular behavior and contraction of the extracellular matrix (ECM).

Polysaccharide monooxygenase-catalyzed oxidation of cellulose to glucuronic acid-containing cello-oligosaccharides

open access: yesBiotechnology for Biofuels, 2019
Background Polysaccharide monooxygenases (PMOs) play an important role in the enzymatic degradation of cellulose. They have been demonstrated to able to C6-oxidize cellulose to produce C6-hexodialdoses. However, the biological function of C6 oxidation of
