Contaminación por microplásticos en playas del Pacífico de Guatemala: abundancia y características

La contaminación por microplásticos (MPs) de tamaño menor a 5 mm ha tomado relevancia en los últimos años debido a su impacto en los ecosistemas. En Guatemala, se carece de información relacionada con MPs, por lo que este estudio tuvo como objetivo evaluar la abundancia y características de MPs en...

Between prolene®, ultrapro® and bard soft® meshes which presents the best performance in the repair of the abdominal wall?

ABCD (São Paulo, Impr.); 34 (1), 2021
ABSTRACT Background: In the definition of the mesh to be used to correct hernias, porosity, amount of absorbable material and polypropylene should be considered in the different stages of healing process. Aim: To evaluate the inflammatory reaction in the use of macro and microporous meshes of high an...

Comparative analysis of tissular response after abdominal wall repair using polypropylene mesh and bovine pericardium mesh

ABCD (São Paulo, Impr.); 34 (3), 2021
ABSTRACT Background: The use of polypropylene meshes for surgical repair of the abdominal wall contributes to a reduction of the of recurrence rates of hernias or defects. However, its intra-abdominal use comes along with the formation of adhesions and several complications. The study and the search for...

Association of polypropylene scaffolds and mesenchymal stem cells for use in tissue engineering

Rev. bras. ciênc. vet; 27 (4), 2020
Tissue engineering replaces injured tissues by manipulating cells, making scaffolds, and using molecules that stimulate the tissue. Mesenchymal stem cells (MSCs) are good candidates for tissue engineering, as this is one of the cell types which are recruited to repair injured tissues. Scaffolds are struc...

Avaliação do uso de membrana de polipropileno na preservação do volume alveolar após exodontias: estudo clínico randomizado prospectivo

O objetivo deste estudo foi mensurar as alterações lineares no alvéolo, por meio de imagens de tomografia computadorizada cone beam, imediatamente após exodontia e após 120 dias usando ou não a membrana de polipropileno. A população deste estudo consistiu de 19 pacientes da Faculdade de Odontolog...

Biomechanical and adhesion comparison of linea alba prophylactic reinforcement with coated and uncoated three-dimensional T-shaped mesh in rabbits

Acta cir. bras; 35 (10), 2020
Abstract Purpose: Incisional hernia (IH) is a frequent complication of median laparotomy. The use of prophylactic mesh to reduce IH incidence has gained increasing attention. We hypothesized that in an animal model, linea alba prophylactic reinforcement with a three-dimensional T-shaped polypropylene me...

Experimental evaluation of intra-abdominal adhesions comparing two different intraperitoneal meshes and the effect of a natural anti-inflammatory product on their formation

Acta cir. bras; 35 (12), 2020
Abstract Purpose: In laparoscopic incisional hernia repair, meshes with a tissue-separating barrier are positioned intraperitoneally. Despite this property, the close contact between mesh and viscera involves a risk of adhesion formation. Some natural products, such as red propolis (RP), could reduce th...

Does a bilateral polypropylene mesh alter the duct deferens morphology, testicular size and testosterone levels? Experimental study in rats

Acta cir. bras; 35 (2), 2020
Abstract Purpose To evaluate the effect of a PP mesh on duct deferens morphology, testicular size and testosterone levels. Methods Forty adult male rats were distributed into groups: 1) no surgery; 2) inguinotomy; 3) mesh placed on the duct deferens; and 4) mesh placed on the spermatic funiculus. Aft...

Use of an Expanded Polytetrafluoroethylene (ePTFE) Dura Substitute in Glioma Surgeries: A Technical Note

Arq. bras. neurocir; 38 (3), 2019
Introduction Reoperations are a common scenario among glioma patients. There is crescent evidence of its benefit in low- and high-grade gliomas. Here we discuss our experience with inert expanded polytetrafluoroethylene (ePTFE) dura substitute in glioma surgeries. Technical note We generally put the ePTF...

Evaluation of polypropylene and polyglactin sutures in primary sphincteroplasty for the treatment of anal fistula in rats

ABSTRACT Rationale: Fistulotomy followed by primary sphincteroplasty is one of the therapeutic options in transsphincteric fistulae; however, it was not known which suture would present a better result. Objective: To compare polypropylene and polyglactin sutures in primary sphincteroplasty in rats subj...
