: A new fibrous adsorbent was prepared by grafting Acrylic Acid /Acryl Amide (AA/AAm) co-monomers onto Poly(Ethylene Terephtalat) (PET) fibers. The resulting sorbent has been characterized by Fourier Transform InfraRed spectroscopy (FT-IR), Thermo Gravimetric Analysis (TGA), Scanning Electron Microscopy (SEM) and elemental analysis and studied for the preconcentration and ...

Background  Many biomaterials are used during the open sinus lift surgery, beneath the elevated scheniderian membrane and maxillary sinus bony floor but the search for Ideal material continues. Methods  In the maxillary posterior atrophic ridges with the bone height less than four millimeters the open sinus lift surgery performed. The autologous Platelet-rich plasma (PRF) was used as the sol...

In recent years, plasma treatments have given good results since they offer high technological efficiency with low waste generation. One of the most important characteristics of plasma methods is their action only on a thin surface layer, whereas the bulk of sample remains unchanged and the modified material keeps its chemical and mechanical properties. In this research, polyurethane membrane s...

OBJECTIVES The aim of this clinical trial was to evaluate the additional benefit of using guided tissue regeneration (GTR) with autogenous cortical bone (ACB) grafting versus ACB grafting alone for the regenerative treatment of intraosseous periodontal defects. METHODS Via a split-mouth design, 12 patients with chronic periodontitis (five men, seven women; mean age, 45.3±4.6 years) who had pr...

TASK FORCE STATEMENT: In 2007, the American Society of Plastic Surgeons formed a task force to conduct an assessment regarding the safety and efficacy of autologous fat grafting, specifically to the breast, and to make recommendations for future research. The task force formulated specific issues regarding fat grafting and then compiled them to focus on five broad-based questions: 1. What are t...

Grafting-to polymer coatings are typically easy to apply, but the thickness of such is limited a few nanometers, which may hamper applications. This paper presents grafting-to coating approach that yields brushes up an unprecedented 19 nm. To this aim, easy-to-apply poly(dopamine) (PDA) primer layer optimized. PDA easy-to-apply, highly complex and chemically not well understood layer. In study,...

Grafting polymerization was a valuable method for the modification of the chemical and physical properties of polymer surfaces. In this paper, the grafting of cationic vinyl monomer with quaternary ammonium groups, methacryloxyethyltrimethyl ammonium chloride (DMC), onto the isotactic polypropylene (iPP) granule was performed by suspension solid-state grafting process. The techniqu...
