This work is an experimental study of the differential scanning calorimetry characterisation of polymer materials used in food packaging materials, such as polypropylene (0·03 mm), polyethylene (0·1 and 0·03 mm), poly(D-(-)-β-hydroxybutyrate) (powder), two-layered polypropylene (0·064 mm), and two-layered polypropylene with poly-vinylidene-chloride (0·012/0·021). The polymer stability was check...

OBJECTIVES The aim of this study was to clarify the short-term and mid-term outcomes of the modified Robicsek procedure using polypropylene mesh for adult pectus excavatum patients. METHODS Retrospective chart review was performed. Between 2001 and 2012, 46 consecutive adult patients underwent modified Ravitch repair using polypropylene mesh for pectus excavatum at our institution. There were...

Exhaled breath condensate collection is not yet standardised and biomarker measurements are often close to lower detection limits. In the current study, it was hypothesised that adhesive properties of different condenser coatings interfere with measurements of eicosanoids and proteins in breath condensate. In vitro, condensate was derived from a collection model using two test solutions (8-isop...

OBJECTIVE To compare surgical fixation of polypropylene mesh (PP) and coated polypropylene mesh (PCD) using polypropylene suture and fibrin glue, as for the formation of intraperitoneal adhesions. METHODS A sample of 46 female Wistar rats were randomized into six groups: two control groups, with five rats each, were subjected to one medial incision (MI) and the other to a U-shaped incision (U...

Influence of the temperature on flow-induced crystallization of isotactic polypropylene and propylene-ethylene random copolymer Influence of the temperature on flow-induced crystallization of isotactic polypropylene and propylene-ethylene rando...

Research on wood-flour-filled polypropylene has primarily focused on one species of wood flour and one or two broad particle-size distributions. To fully exploit the use of wood flour as a filler, the effects of species and particle size need to be examined. This study focused on the effects of both of these variables on the properties of polypropylene filled with wood flour. To examine the eff...

In football, injuries from opponent contact occur commonly in the lower extremities. FIFA the world's governing body for football requires players to wear shin guards. The aim of this study was to compare the protective effectiveness of polypropylene based shin guards with custom-made carbon fiber ones. Three commercial polypropylene shin guards (Adidas Predator™, Adidas UCL™, and Nike Mercuria...

BACKGROUND Pain associated with infiltrating the skin with lidocaine can be reduced by buffering the solution with sodium bicarbonate. OBJECTIVES To determine the physical compatibility and chemical stability of lidocaine hydrochloride solution buffered with 8.4% sodium bicarbonate, with and without epinephrine, packaged in polypropylene syringes and stored at 5°C with protection from light. ...

BACKGROUND AND AIM Prosthetic mesh repair for abdominal wall hernias is widely used because of its technical simplicity and low hernia recurrence rates. The most commonly used material is pure polypropylene mesh, although newer composite materials are recommended by some centers due to their advantages.However, these meshes are more expensive than pure polypropylene meshes. Resterilization of a...
