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...

PURPOSE To evaluate if latex coated polypropylene mesh leads to less adhesions formation. METHODS 90 rats were distributed in three groups. Group I (control) was submitted to median laparotomy and posterior synthesis; Group II (polypropylene) was submitted to a segment resection of the abdominal wall, and the defect was corrected with a polypropylene mesh; Group III using the new material (la...

Objective: This study was done to evaluate the clinical efficacy of polypropylene for stenting in endoscopic revision dacryocystorhinostomy. Patients and methods: Revision endoscopic dacryocystorhinostomy operation was performed in 10 patients (4 men and 6 women) between 2009 and 2014.After recreating an aperture in the medial wall of the lacrimal sac, 2/ 0 polypropylene suture material was ins...

Lignocellulose nanofibers were prepared by the wet disk milling of wood flour. First, an ethylene-butene copolymer was pre-compounded with wood flour or lignocellulose nanofibers to prepare master batches. This process involved evaporating the water of the lignocellulose nanofiber suspension during compounding with ethylene-butene copolymer by heating at 105 °C. These master batches were compou...

BACKGROUND Static facial suspension (SFS) continues to play a role for rehabilitation in patients with facial paralysis. We perform SFS almost exclusively with a suture technique in our practice. Monofilament polypropylene suture (Prolene) is commonly used for SFS, but we have witnessed occasional failure and some stretching with this material. The purpose of this study was to establish and com...

Separation of peptides and proteins by capillary zone electrophoresis suffers from the interaction of these solutes with the capillary wall which results in the formation of broad peaks and low resolution. To minimize the protein/peptide-capillary wall interaction we tried to use Pluronic F127, a triblock copolymer of the general formula (polyethylene oxide)(x)(polypropylene oxide)(y)(polyethyl...

The creation of highly oriented, co-extruded polypropylene (PP) tapes allows the production of recyclable ‘all-polypropylene’ composites, with a large temperature processing window (O30 8C) and a high volume fraction of highly oriented PP (O90%). These composites show little deviation of mechanical properties with compaction temperature. This paper introduces all-polypropylene composites and re...
