The use of polypropylene mesh devices for Pelvic Organ Prolapse (POP) spread rapidly during the last decade, yet our knowledge of the mesh-tissue interaction is far from complete. We aimed to perform a thorough pathological examination of explanted POP meshes and describe findings that may explain mechanisms of complications resulting in product excision. We report a spectrum of important findi...

A series of transition metal complexes with two thiosemicarbazide Schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (ABTSC) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (TCTS) were synthesized with Co(II), Ni(II), Zn(II), Cd(II) and Ag(I) salts (chloride and acetate). These complexes were characterized by different methods including proton nuclear magnetic resonance (1HNMR),...

The huge scale of plastic waste generation and its environmental consequences drive the demands for catalytic upcycling processes. Here, we report efficient polypropylene (PP) hydro-conversion over Ru Ni supported on a sol-gel anatase TiO2 (TiO2-A-SG). A small number Brønsted acid sites TiO2-A-SG enables hydrocracking, improving efficiency, steering selectivity towards high-valued C4-20, allowi...

In propylene (C3) polymerization with Ziegler-Natta catalyst, not only internal donor but also external is very important to make isotactic polypropylene (PP) higher yield. Most propylene-based polymers have been commercially produced catalysts combined dialkyl-dialkoxy silane compounds (R2Si(OR)2) such as C-donor, P-donor, and D-donor donors. this paper, we will introduce the performance amino...

The aim of this study was to obtain new catalysts for the processing carbon-containing polymer waste based on polyethylene and polypropylene, represented mostly by lids from beverages bottled in plastic containers, which accumulate huge quantities landfills, method thermocatalytic hydrogenation into liquid fuels other products. process carried out presence fuel oil as a binder, source hydrogen ...

Background Polypropylene material is widely used in gynecological surgery. There are few reports regarding its carcinogenic potential. There is lack of evidence supporting tumor formation directly attributed to the use of polypropylene material. Case This patient is a 49-year-old woman with a history of stress urinary incontinence which required a MiniArc® Sling who presented with a hard, ten...

Objective: To evaluate surgical handling, prolapse correction and complication rate of polypropylene mesh. Methods: A retrospective review of patients who had pelvic floor repair using polypropylene mesh(PPM) and intra-vaginal sling(IVS), between January 2003 and July 2005. All patients were followed-up for a period of 6weeks to 12months.The effectiveness and complications following PPM inserti...

Background: The tension-free hernioplasty as introduced by Lichtenstein has gained increasing acceptance during the last decade. This study compared two methods of mesh fixation. Material and Methods: Fifty-four patients undergoing sixty repairs were randomized into two groups. In control group polypropylene mesh was secured with 2/0 polypropylene sutures and skin closed with 2/0 polyamide blac...

In this review, we report on the use of low pressure plasmas for elaborating materials at the heart of solid polymer fuel cells (SPFC), especially electrodes and the membrane electrolyte. Electrodes are formed using plasma sputtering techniques while the ion conducting membranes are built up using plasma polymerization. Fuel cell performance will be improved by these approaches. The electrode c...
