ABSTRACT:Polycyanoacrylate is a very promising matrix for polymer electrolyte,which possesses advantages of strong binding and high electrochemical stability owing to the functional nitrile groups. Herein, a facile and reliable in-situ polymerization strategy of poly(ethyl cyanoacrylate) (PECA) based gel polymer electrolytes (GPE) via a high efficient anionic polymerization was introduced consisting of PECA and 4 M LiClO4 in carbonate solvents. The in-situ polymerized PECA gel polymer electrolyte achieved an excellent ionic conductivity (2...

A 68-year-old woman, previously treated with embolization of the thoracic duct with Lipiodol (an ethiodized oil injection) and cyanoacrylate glue (a topical tissue adhesive), was admitted with an asymptomatic mass in the inferior vena cava (IVC) and right atrium. The mass was surgically removed, and pathologic analysis revealed a Lipiodol-containing thrombus. To our knowledge, this is the first clinicopathologic report of Lipiodol-induced thrombus presenting as an intracavitary mass.

The less traumatic use of surgical adhesives rather than sutures for mesh fixation in hernia repair has started to gain popularity because they induce less host tissue damage and provoke less postoperative pain. This study examines the host tissue response to a new cyanoacrylate (CA) adhesive (n-octyl, OCA). Partial defects (3 × 5 cm) created in the rabbit anterior abdominal wall were repaired by mesh fixation using OCA, Glubran2(®)(n-butyl-CA), Ifabond(®)(n-hexyl-CA) or sutures. Samples were obtained at 14/90 days for morphology, collagens qRT-PCR/immunofluorescence and biomechanical studies...

Granulomas are rarely seen in gastric biopsies mostly as an involvement of granulomatous diseases like sarcoidosis, Crohn's disease, infections, neoplasms, and vasculitis. Here, we claim cyanoacrylate as a foreign body type granuloma-causing agent in the stomach after vascular embolisation. We present cyanoacrylate associated gastric changes of three cases: two endoscopic biopsies and one gastric resection. In two cases, cyanoacrylate associated ulcers and granulomatous inflammation were observed in gastric mucosal biopsies following endoscopic examination after 7 months and 6 years of the glue injections, respectively...

Protein adsorption on nanoparticles (NPs) used in nanomedicine leads to opsonization and activation of the complement system in blood, which substantially reduces the blood circulation time of NPs. The most commonly used method to avoid protein adsorption, is to coat the NPs with polyethylene glycol, so called PEGylation. Although PEGylation is of utmost importance for designing the in vivo behavior of the NP, there is still a considerable lack of methods for characterization and fundamental understanding related to the PEGylation of NPs...

The Cognard type V dural arteriovenous fistula (dAVF), which has a drainage route into the spinal vein, is a rare subtype of cranial dAVF. Because of typical features such as progressive myelopathy and brainstem dysfunctions, aggressive treatments should be considered. To eliminate venous congestion of the spinal cord, various approaches including surgical interruption of the spinal draining vein or transarterial embolization with cyanoacrylate have been reported. The introduction of nonadhesive Onyx has changed the treatment of dAVF, although little is known about the clinical usefulness of this type of fistula...

Treatment of cryptococcal meningitis with antifungals such as itraconazol is difficult due their low concentration in the brain. Therefore, drug carriers with high payload are highly desired. But, generation of itraconazole loaded poly(butyl cyanoacrylate) nanoparticles with higher drug load, for instance more than 20% drug, is challenging. In present study we were able to generate novel highly loaded itraconazole poly(butyl cyanoacrylate) nanocapsules containing up to 99% (w/w) itraconazole and 1% polymer (w/w)...

INTRODUCTION: Temporomandibular joint (TMJ) ankylosis causes disability through impaired digestion, mastication, speech and appearance. Surgical treatment increases range of motion with resultant functional improvement. However, substantial perioperative blood loss can occur, up to three liters, if the internal maxillary artery (IMAX) is injured as it traverses the ankylotic mass. Achieving hemostasis is difficult due to limited proximal IMAX access and poor visualization. Our aim is to investigate the technical feasibility and preliminary safety of preoperative IMAX embolization in patients undergoing TMJ ankylosis surgery...

Vascular embolization is a minimally invasive treatment used for the management of vascular malformations and tumors. It is carried out under X-ray by navigating a microcatheter into the targeted blood vessel, through which embolic agents are delivered to occlude the vessels. Cyanoacrylate liquid glues have been widely used for vascular embolization owing to their low viscosity, rapid polymerization/solidification rate, good penetration ability and low tissue toxicity. The objective of this study is to quantitatively investigate the physical properties of two n-butyl cyanoacrylate (nBCA) glues (Glubran 2 and Histoacryl) mixed with an iodized oil (Lipiodol) at various concentrations...

Metal-free near-infrared (NIR) active unsymmetrical squaraine dyes, RSQ1 and RSQ2, with benzodithiophene (BDT) π-spacer and cyanoacrylic acid acceptor were synthesized by utilizing palladium catalyzed direct (hetero)arylation reaction. Methyl and 2-ethylhexyl groups were strategically placed at the BDT unit for RSQ1 and RSQ2, respectively, to investigate the effect of alkylated π-spacer on dye aggregation on the TiO2 surface and recombination reactions at TiO2/dye/electrolyte interface. These dyes have strong absorption (ε > 10(5) M(-1) cm(-1)) in near-infrared (NIR) region and exhibit similar optical and electrochemical properties as they have same conjugated framework...

​We retrospectively reviewed the records of 3 patients (3 knees) with a delayed type hypersensitivity reaction following Dermabond exposure after an orthopaedic knee procedure. Delayed hypersensitivity reactions are mediated by CD4+ helper T cells. The use of skin adhesives in place of traditional sutures is increasing in popularity given Dermabond's potential benefits of decreased wound infection rate and better wound approximation. However, hypersensitivity reactions to the cyanoacrylate material in Dermabond have been described...
