Coaxial Spinning of All-Cellulose Systems for Enhanced Toughness: Filaments of Oxidized Nanofibrils Sheathed in Cellulose II Regenerated from a Protic Ionic Liquid

Spinning of Cellulose Nanofibrils into Filaments: A Review

Spinning of cellulose nanofibrils (CNF) offers promising opportunities to develop renewable fibers and filaments with strong, aligned structure. This review introduces recent findings on the relationship between the properties of CNF hydrogels, the spinning conditions and the performance of filaments obtained by dryand wet-spinning. For example, the filament Young’s modulus correlates with CNF ...

Oxidized Regenerated Cellulose Resembling Vaginal Cuff Abscess

INTRODUCTION Application of oxidized regenerated cellulose is commonly performed in laparoscopy to achieve hemostasis during surgery. The appearance of an abscess resembles oxidized regenerated cellulose, causing imaging studies to be difficult to interpret. CASE DESCRIPTION We describe the cases of 3 patients who underwent oxidized regenerated cellulose placement during laparoscopic gynecolo...

Efficacy of Oxidized Regenerated Cellulose, SurgiGuard®, in Porcine Surgery

PURPOSE Adequate hemostasis is important for postoperative outcomes of abdominal surgery. This study evaluated the hemostatic effects and accompanying histopathological changes of a novel oxidized regenerated cellulose, SurgiGuard®, during abdominal surgery. MATERIALS AND METHODS Ten pigs underwent wedge resection of the spleen (1×1 cm) and liver (1.5×1.5 cm). The resected surface was covered...

Oxidized Regenerated Cellulose/Collagen Dressings: Review of Evidence and Recommendations

OBJECTIVE Healthcare systems are being challenged to manage increasing numbers of nonhealing wounds. Wound dressings are one of the first lines of defense in wound management, and numerous options exist. The oxidized regenerated cellulose (ORC)/collagen dressing may offer healthcare providers a robust and cost-effective tool for use in a variety of wounds. DESIGN A multidisciplinary panel mee...
