We measure the coexistence curve and the critical point properties of a binary mixture composed by polymethylmethacrylate (PMMA) at Mw = 55900 g/mol with 3octanone. This binary mixture which has a demixing transition with an upper critical solution temperature Tc has indeed interesting properties which may be useful for several application : a) its correlation length is larger than that of a li...

Study Design Mechanical study. Purpose To compare the pullout strength of different screw designs and augmentation techniques in an osteoporotic bone model. Overview of Literature Adequate bone screw pullout strength is a common problem among osteoporotic patients. Various screw designs and augmentation techniques have been developed to improve the biomechanical characteristics of the bone-...

BACKGROUND Fungal infected denture, which is typically composed of polymethylmethacrylate (PMMA), is a common problem for a denture wearer, especially an elderly patient with limited manual dexterity. Therefore, increasing the antifungal effect of denture by incorporating surface modification nanoparticles into the PMMA, while retaining its mechanical properties, is of interest. AIM OF THE ST...

BACKGROUND Conventional local treatment for medullary osteomyelitis (OM) includes insertion of antibiotic-loaded polymethylmethacrylate (PMMA) cement. Nevertheless, PMMA may delivery irregular concentration of antibiotic to surrounding tissue. We aimed to compare the in vitro antibacterial activity of Bioactive Glass (BAG) S53P4, which is a compound showing local antibacterial activity, to that...

Pediatric cataract is totally different from adult cataract. The objective of this review article is to describe the peculiarities of pediatric cataract and the controversies and practices in pediatric cataract surgery. The differences in the surgical technique are discussed in the article. There are lots of controversies regarding IOL implantation in children. The result of the review is that ...

BACKGROUND The rate of recurrence of giant cell tumor of bone is decreased by use of adjuvant treatments such as phenol, liquid nitrogen, or polymethylmethacrylate (PMMA) during curettage. We assessed recurrence and complication rates and functional outcome after curettage with use of phenol and PMMA, liquid nitrogen and PMMA, and liquid nitrogen and bone grafts. METHODS We retrospectively co...

DA Classen. Antibiotic bead pouch dressing. Can J Plast Surg 1996;4(4):199-202. The antibiotic bead pouch is a dressing consisting of antibiotic laden polymethylmethacrylate (PMMA) beads placed in a wound, which is covered by a porous membrane (Opsite). This paper outlines the method, rationale and results of the use of this dressing technique for extensive wounds before definitive wound closur...

Gentamicin incorporated in beads of polymethylmethacrylate has been shown capable of being released over a period of several months in concentrations sufficiently high to control most pathogens. The therapeutic efficacy of such beads has been demonstrated in a model of osteomyelitis of the femur in the dog. Good tolerance has been shown, both in the animal model and in tissue cultures. In forty...

This paper describes a quantitative immunoassay chip harnessing EOF (electroosmotic flow) in glass fiber sheet. The chip consists of a glass fiber sheet-based channel covered with PMMA (polymethylmethacrylate) frames and antibody-immobilized microbeads at the observation spot (Fig. 1). Applying EOF, another labeled-antibody and rinsing buffer sequentially migrate through the antigen-antibody co...
