Oxidized cellulose-based hemostatic materials
Carbohydrate Polymers, 2020The application of hemostatic agents is essential to prevent significant blood loss and death from excessive bleeding in surgical or emergency scenarios. Oxidized cellulose is an excellent biodegradable and biocompatible derivate of cellulose, which has become one of the most important hemostatic agents used in surgical procedures.

Conference Record of the 2008 IEEE International Symposium on Electrical Insulation, 2008
Oxidation ageing experiments on paper and transformer oil insulation has been performed using two different techniques. First, we used oxygen pressurized bottles with oil-paper isolation where oil and paper are sampled at certain intervals during 8 months and degree of polymerization is measured.

Biodegradation of oxidized regenerated cellulose
Carbohydrate Research, 1990The in vitro solubilization and degradation of regenerated cellulose was studied under conditions which approximate those found in vivo, when the material is used as an adhesion barrier to assist normal wound repair. Factors affecting solubilization which were examined included the effects of serum or plasma, and the presence of hydrolytic enzymes ...

Periodate Oxidation of Crystalline Cellulose
Biomacromolecules, 2000Conversion of 1,2-dihydroxyl groups to dialdehyde by periodate oxidation is a useful method of derivatizing polysaccharides but has not been extensively utilized in derivatization of cellulose because of complicacy due to the crystalline nature of cellulose.

Regioselectively Oxidized Cellulose Ethers
Macromolecular Symposia, 2009AbstractSummary: 3‐Mono‐O‐(2‐methoxyethyl) cellulose (MEC) was selectively oxidized with 2,2,6,6‐tetramethyl‐1‐piperidinyloxy radical (TEMPO)/NaBr/ NaOCl. According to 1D and 2D NMR measurements, the primary hydroxyl group was completely oxidized without affecting the secondary one at position 2.

Oxidized Regenerated Cellulose Imitating Pelvic Abscess
Obstetrics & Gynecology, 2013Oxidized regenerated cellulose is a topical hemostatic agent that is used commonly in abdominal and pelvic surgery. Although oxidized regenerated cellulose mimicking an abscess has been reported after different operations, little is known about its side effects after gynecologic surgery.Two women were diagnosed with postoperative abscess and intra ...

PERITONEAL REACTION TO OXIDIZED CELLULOSE
Archives of Surgery, 1948RECENTLY there has been added to the armamentarium of the surgeon a gauzelike material which is completely absorbed in the tissues and serous cavities. This material is known as oxidized cellulose. Its physical and chemical properties have already been thoroughly described in the literature.

TEMPO-Mediated Oxidation of Cellulose III
Biomacromolecules, 2003Various cellulose samples converted into cellulose III by two different ammonia treatments, either liquid or gaseous, were reacted with catalytic amounts of 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO), sodium hypochlorite, and sodium bromide in water.

Oxidized Regenerated Cellulose for Hepatic Hemostasis
Archives of Surgery, 1963Introduction Oxidized regenerated cellulose is a relatively recent addition to the surgeon's armamentarium for hemostasis. Its hemostatic and absorbable qualities have been attested to by several authors in recent articles. 1-5 There have also been several articles describing its chemical nature, the mechanism of solubility in human tissues, and ...

Oxidation of macroradicals in celluloses and cellulose nitrate
Polymer Science U.S.S.R., 1990The ESR method has been used to study the reaction of oxidation of macroradicals in UV- and γ-irradiated cotton cellulose and cellulose nitrate with oxygen dissolved in these polymers. The degree of oxidation of the alkyl radicals in the polymers studied did not exceed 30% which is apparently linked with the diffusion difficulties of access of oxygen ...
