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 ...

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 ...

Microplastics have been found in all hemispheres of the world. However, studies on microplastics are mainly conducted Europe, North America, and East Asia. Few reported Southeast Asian region, where a large number plastic waste is disposed improperly into water. This study investigated abundance characteristics surface water Chao Phraya River (Thailand), Citarum (Indonesia), Saigon (Vietnam). S...

Background: Polypropylene meshes are commonly used in laparoscopic inguinal hernia repair, although they may cause complications. In this prospective study, a polyester mesh was compared to a polypropylene mesh. Methods: Transabdominal preperitoneal (TAPP) laparoscopic repair was performed in 160 consecutive male patients suffering from unilateral inguinal hernia. The first 80 cases received a ...

Maleic anhydride-modified polypropylene was compounded with commercially available surface-modified montmorillonite in a twin-screw extruder. Recompounding ensured the removal of visible tactoids from the extrudate but TEM and XRD techniques showed nonuniform dispersion of clay platelets. In this study, we investigated the mechanical and fracture properties of nanoclayfilled polypropylene. Emph...
