13. Effect of platelet-rich plasma on polypropylene meshes implanted in the rabbit vagina: histological analysis
ABSTRACT Purpose The polypropylene mesh (PPM) is used in many surgical interventions because of its good incorporation and accessibility. However, potential mesh-related complications are common. Platelet-rich plasma (PRP) improves the healing of wounds and is inexpensive. Thus, the purpose of this study was to analyze the effect of the PRP-gel coating of

14. Axial Crushing of Concentric Expanded Metal Tubes Under Impact Loading
Abstract This paper investigates the axial crushing response of concentric expanded metal tubes under impact loading. The study is conducted by means of nonlinear finite element simulations, considering the speed of deformation and the size of the expanded metal cells. In the analysis, two tubes are placed concentrically and then axially crushed with an impa

15. Finite Element Modeling and Experimental Verification of Nitriding Process in S30C Steel
A mathematical model has been developed to simulate the nitriding process of plain carbon steel, considering the simultaneous diffusion of nitrogen in different iron-nitrogen (Fe-N) phases and the precipitation dynamics of γ' and ε iron-nitride. The model can predict the distribution of nitrogen concentration, volume fraction of Fe-N phases and hardness. F

16. Comparative study of Polypropylene versus Parietex composite®, Vicryl® and Ultrapro® meshes, regarding the formation of intraperitoneal adhesions
Abstract Purpose: To compare the polypropylene mesh (Marlex®) to Vicryl®, Parietex composite® and Ultrapro® meshes to assess the occurrence of adhesions in the intraperitoneal implantation. Methods: Sixty Wistar rats were allocated into three groups: PP+V, in which all the animals received a polypropylene and a Vicryl® mesh; PP+PC, with the implanta

18. Influence of high-dose gamma radiation and particle size on antioxidant properties of Maize ( Zea mays L.) flour
ABSTRACT Influence of high-dose gamma radiation and particle size on antioxidant properties of maize (Zea mays L.) flour was studied using response surface methodology. A central composite design based on three levels of each of particle size, in terms of mesh number (40, 60 and 80 meshes), and gamma radiation dose (25, 50 and 75 kGy) was constructed. A stat

19. Energy Absorption Characteristics of Coiled Expanded Metal Tubes Under Axial Compression
Abstract This paper presents an experimental investigation on the axial crushing of coiled expanded metal tubes subjected to quasi-static compressive loading. The investigation aims at comparing the energy absorption characteristics between tubes fabricated with coiled expanded metal meshes and solid plates. Then, a series of quasi-static axial crushing test

20. Ventral abdominal wall defect correction in rats with contaminated meshes
ABSTRACT PURPOSE: To investigate whether there is a difference between Marlex(r) and Dynamesh PP-light Marlex(r) meshes, in the abdominal wall defect correction, on rats in contaminated surgical site. METHODS: Twenty-eight Wistar rats were divided into two groups of 14, and four subgroups of seven animals. All subgroups underwent similar surgical procedure

21. Histological response to platelet-rich plasma added to polypropylene mesh implemented in rabbits
ABSTRACT Introduction: The platelet-rich plasma (PRP) is part of a set of biotechnologies, providing some growth factors that promote repair of different tissues. The polypropylene meshes (PPM) are applied in the correction of abdominal defects, pelvic floor and urinary incontinence, however, they induce many significant complications, as a result of an ina

23. Characteristics of the fibroplasia and collagen expression in the abdominal wall after implant of the polypropylene mesh and polypropylene/polyglecaprone mesh in rats
ABSTRACT PURPOSE: To compare fibroplasia and the resistance of the abdominal wall when polypropylene meshes and polypropylene/poliglecaprone are used. METHODS: Seventy-seven male Wistar rats were divided into three groups: Control Group (for resistance); Group E (polypropylene mesh); and Group U (polypropylene/poliglecaprone mesh). The animals in Groups E
