OBJECTIVE to compare intraperitoneal adhesion formation in rats when using polypropylene and polypropylene with poliglecaprone meshes. METHODS we used twenty male, Wistar rats, divided in two groups. In group 1, the rats received the polypropylene mesh on their right side and the polypropylene with poliglecaprone mesh on their left side. In group 2 the position of the meshes was inverted. Aft...
BACKGROUND Hernia correction is a routinely performed treatment in surgical practice. The improvement of the operative technique and available materials certainly has been a great benefit to the quality of surgical results. The insertion of prostheses for hernia correction is well-founded in the literature, and has become the standard of treatment when this type of disease is discussed. AIM T...
OBJECTIVE To examine any association between polypropylene mesh used in midurethral slings and malignancy in humans. Macroporous, monofilament polypropylene midurethral slings have been established as a safe and effective treatment for stress urinary incontinence. However, despite long-term studies supporting the efficacy and safety of midurethral slings, there have been concerns regarding the ...
Supercritical CO₂ Foaming of Radiation Cross-Linked Isotactic Polypropylene in the Presence of TAIC.
Since the maximum foaming temperature window is only about 4 °C for supercritical CO₂ (scCO₂) foaming of pristine polypropylene, it is important to raise the melt strength of polypropylene in order to more easily achieve scCO₂ foaming. In this work, radiation cross-linked isotactic polypropylene, assisted by the addition of a polyfunctional monomer (triallylisocyanurate, TAIC), was employed in ...
The objective of this study is to compare Polydioxanone (PDS) and Polypropylene (PPL) suture material for fascial closure,in midline abdominal incisions using interrupted X sutures in terms of postoperative wound complications. Patients for clinical study were selected from the surgical wards of Mc-Gann Teaching and District Hospital, SIMS from Jan 2012 to Dec 2013 with the following inclusion ...
Abstract. In this research, four novel types of hyperbranched polyester polymers (HBPs) were used and blended with polypropylene polymer PP, virgin VPP recycled rPP, using a twin-screw extrusion machine. Hyperbranched was added in different weight ratios (5%, 10%, 20%). The Fourier transform spectroscopy FTIR, the water contact angle CA, biodegradation soil, rheological properties (melt flow ra...
