Although nanotoxicology has become a large research field, assessment of cytotoxicity is often reduced to analysis of one cell line only. Cytotoxicity of nanoparticles is complex and should, preferentially, be evaluated in several cell lines with different methods and on multiple nanoparticle batches. Here we report the toxicity of poly(alkyl cyanoacrylate) nanoparticles in 12 different cell li...

Hemobilia is a rare phenomenon. In this case report we present an emergent transcatheter glue embolization (in which N-butyl cyanoacrylate is used as an embolizing agent) due to arteriobilary fistula occurred following the laparoscopic cholecystectomy in a 41-year-old woman.

Bacteria-mediated degradation of toxins has been reported as a practical technique for the innocuous removal of toxic organic compounds from water. Specifically, immobilized and pre-acclimatized Pseudomonas putida has been shown to clear low levels of contaminants (less than 2000 mg/L) from wastewater, wherein the bacteria consumes toxic aromatic compounds as the only source of carbon and energ...

BACKGROUND Although splenic artery aneurysms (SAAs) are common, their giant forms (more than 10 cm in diameter) are rare. Because of the variety of forms and locations of these aneurysms, there are a lot of therapeutic methods to choose. In our case of a giant true aneurysm we performed an endovascular embolization with N-butyl-cyano-acrylate (NBCA) glue. To our knowledge it is the first report...

OBJECTIVE The aim of this study was to find a proper experimental design and to evaluate n-butyl-2-cyanoacrylate (Histoacryl) as a fixation method for a light-weight and large pore PP mesh (Synthetic PP Mesh-1) using the sheep as an animal model. METHODS Posterior vaginal implantation by means of episiotomy was used to implant 8 ewes which were evaluated macroscopically and histologically at ...

Waterborne fluoropolymer emulsions were synthesized using the one-step semi-continuous seed emulsion polymerization of chlorotrifluoroethylene (CTFE), vinyl acetate (VAc), n-butyl acrylate (BA), Veova 10, and acrylic acid (AA). The main physical parameters of the polymer emulsions were tested and analyzed. Characteristics of the polymer films such as thermal stability, glass transition temperat...

PURPOSE To assess the effectiveness, initial and long term, of embolization using polyvinyl alcohol particles (PVA) particles in patients with spinal dural arteriovenous fistulas (SDAVF). METHODS The initial treatment in 14 patients with SDAVF was embolization with PVA particles. Postembolization occlusion of the SDAVF was documented angiographically in all cases. RESULTS All 14 patients in...

Substantial intraoperative bleeding during surgical removal of carotid body tumor may be a major problem in the management of these highly vascularized tumors. Traditional preoperative embolization via a transarterial access has proved effective but is often limited by complex vascular anatomy and small feeding vessels that is difficult to catheterize. We report two cases of carotid body tumor ...

OBJECTIVE The purpose of this study was to evaluate the technical feasibility and clinical efficacy of percutaneous transabdominal treatment of endoleaks after endovascular aneurysm repair. MATERIALS AND METHODS Between 2000 and 2007, six patients with type I (n = 4) or II (n = 2) endoleaks were treated by the percutaneous transabdominal approach using embolization with N-butyl cyanoacrylate ...

Core-shell polymers in the particle size range 200–300 nm having a monodisperse distribution and opal color are prospective materials for coating applications. The emulsion polymerization of the core-shell was done using two monomers with significantly different refractive indices styrene for the hard monomers and butyl acrylate for the soft monomers. The feeding and aging time were varied, wit...
