The objective of this study was to present an effective injectable adhesion barrier comprised of TEMPO-oxidized cellulose nanofiber (TOCN), methyl cellulose, carboxymethyl cellulose, and polyethylene glycol. Hydrogels with different concentrations (0.2, 0.5, 0.8, 1% w/v) of bio compatible TOCN were investigated to determine their abilities to prevent post-surgical peritoneal adhesion using a rat cecal wall abrasion model. Sol-gel transition at body temperature (37 °C) was optimized by adjusting concentration of sodium ions (Na+ ), with a gelation time of 45 ± 7 s...

Three different heterologous substitutes for bone regeneration, manufactured with equine-derived cortical powder (CP), cancellous chips (CC) and demineralized bone matrix granules (DBM), were compared in in vitro and in vivo settings. We tested: a commercially available bone paste (Osteoplant-Activagen™, consisting of aqueous collagenous carrier, CP, DBM; named A); a second-generation injectable paste (20 kDa polyethylene glycol/hydroxypropyl-methyl cellulose-based hydrogel, CP, DBM; B); a pre-formed bone filler (400 kDa polyethylene oxide/hydroxypropyl-methyl cellulose-based hydrogel, CP, CC, DBM; C)...

An injectable composite silanized hydroxypropyl methyl cellulose/biphasic calcium phosphate (Si-HPMC/BCP) has been investigated in humans with promising results. The aim of this study was to evaluate his efficacy for treating periodontal defects (canine fenestration and premolar furcation) in dog models. At 3 months, we observed that bone formation around BCP particles in furcation model is more discernible but not statistically significant in defects filled with Si-HPMC/BCP compared to healing in control...

Calcium phosphate bioceramic granules associated with hydrosoluble polymers were developed as bone substitutes for various maxillofacial and orthopaedic applications. These injectable bone substitutes, support and regenerate bone tissue and resorb after implantation. The efficiency of these multiphasic materials is due to the osteogenic and osteoconductive properties of the microporous biphasic calcium phosphate. The associated hydrosoluble polymers are considered as carriers in order to achieve the rheological properties of injectable bone substitutes (IBS)...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
