More than just a urinary catheter: achieving hemostasis using Foley catheter in deep cerebral cavities—technical nuances

open access: yesEgyptian Journal of Neurosurgery, 2021
Background Achieving hemostasis during neurosurgical procedures within deep seated tumors is of paramount importance. Chemical methods like using ORC and gel foam are preferred to bipolar cautery as bipolar cautery causes thermal injury to the normal ...

Oxidation of cellulose in pressurized carbon dioxide [PDF]

open access: yes, 2009
This work presents first results upon oxidation of type II cellulose by nitrogen dioxide dissolved in carbon dioxide at high pressure. This reaction leads to oxidized cellulose, a natural-based bioresorbable fabric used for biomedical applications.

Approaches in biotechnological applications of natural polymers [PDF]

open access: yes, 2016
Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic ...

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 regenerated cellulose in cardiac computer tomography imaging [PDF]

open access: yesInteractive CardioVascular and Thoracic Surgery, 2011
Oxidized regenerated cellulose is widely used as a bioabsorbable topical hemostatic agent. Postoperative visualization of this material through routine chest imaging, such as conventional radiography, computer tomography (CT), magnetic resonance imaging as well as sonography, may prove difficult and, to our knowledge, is not described in the literature.

Manufacturing Of Robust Natural Fiber Preforms Utilizing Bacterial Cellulose as Binder [PDF]

open access: yes, 2014
We present a novel method of manufacturing rigid and robust short natural fiber preforms using a papermaking process. Bacterial cellulose acts simultaneously as the binder for the loose fibers and provides rigidity to the fiber preforms.
