BACKGROUND Extramedullary hematopoiesis depends on complex pathophysiological mechanisms linked to hematopoietic stem cells and the proteins considered mediators of the inflammation. The identification of hematopoietic cells outside bone marrow in the adult is an occurrence that can occasionally follows the inflammatory response, was considered a secondary occurrence, but current biomolecular s...

OBJECTIVE To assess the efficacy and complications of surgical repair of incisional hernias by grafting of polypropylene mesh surrounded by fibrous tissue, compared to polypropylene mesh. METHODS twenty-five male and female Wistar rats were divided into two groups: control and experimental. The 15 animals of the experimental group underwent implantation of the mesh in the subcutaneous tissue....

PURPOSE Female stress urinary incontinence (SUI), the involuntary leakage of urine, is a highly prevalent social and hygiene problem, and various surgical techniques have been developed to correct it. This study used the technique of an aponeurosis sling made from the rectus abdominis muscle as a standard and compared the technique to a sling made with a polypropylene mesh, (Marlex). MATERIAL...

The super-Brownian motion X % in a super-Brownian medium % constructed in DF96a] is known to be persistent (no loss of expected mass in the longtime behaviour) in dimensions one ((DF96a]) and three ((DF96b]). Here we ll the gap in showing that persistence holds also in the critical dimension two. The key to this result is that in any dimension (d 3); given the catalyst, the variance of the proc...

A steam sterilizer (autoclave) was tested to determine the operating parameters that affected sterilization of microbiological waste. Tests involved standardized loads (5, 10 ad 15 lb [ca. 2.27, 4.54, and 6.80 kg, respectively]) contaminated petri plates in autoclave bags placed in polypropylene or stainless steel containers. Thermal and biological data were obtained by using a digital potentio...

The present study evaluated the possible effects of exposure to polypropylene flock on respiratory health and serum cytokines in a cross-sectional study of workers from a plant in Turkey. A total of 50 polypropylene flocking workers were compared to a control group of 45 subjects. All subjects filled out a respiratory questionnaire and underwent a physical examination, a chest radiograph and pu...

Visible light photocatalytic H(2) production from water splitting is of great significance for its potential applications in converting solar energy into chemical energy. In this study, a series of Zn(1-x)Cd(x)S solid solutions with a nanoporous structure were successfully synthesized via a facile template-free method at room temperature. The obtained solid solutions were characterized by X-ray...

Objective: The aim of this study was to compare the use of Polypropylene mesh (Prolene) and Sepramesh, a coated Polypropylene mesh with a protective layer of Seprafilm on its visceral side, for the repair of abdominal wall defects in horses. We also aimed to quantify the consequent visceral adhesion and tissue inflammatio Design: Experimental study. Animals: Ten horses. Methods: The horses w...
