PURPOSE To report a specific line of research developed at the University of São Paulo/Brazil on fibrin glue used for sealing corneal perforations and the perspectives of use on non-perforated corneal ulcers and photorefractive keratectomy-operated corneas. METHODS To describe fibrin glue manufacture, development of a device to test the glued perforated corneal area resistance, subsequent exp...

BACKGROUND Controversies surrounding the efficacy of sealants against alveolar air leak (AAL) are abundant in the literature. We sought to test the widely used sealants, TachoSil (Takeda Pharmaceutical Company Limited, Osaka, Japan) and BioGlue (CryoLife Europa Ltd., Surrey, United Kingdom) in an in vitro model. Materials and METHODS After creation of a focal superficial defect (40 × 25 mm) i...

BACKGROUND The management of an enterocutaneous fistula poses a significant challenge to surgeons and is often associated with a costly hospital stay and long-term discomfort. The use of fibrin glue in the fistula tract has been shown to promote closure of low output enterocutaneous fistulas. Our previous nonrandomized study demonstrated that autologous platelet-rich fibrin glue treatment signi...

Analysis of laser assisted frit sealing processes for high CTE > 5x10/°C (coefficient of thermal expansion) glasses was done. The method is based on the thermal fusion of two glasses with a low melting point glass frit. This method is used when thermal sensitive materials such as OLED (organic light emissive device) are present in the glass package. The frit is selected to be highly absorbent a...

The aim of this study was to compare the genotypic diversity and virulence traits of Streptococcus mutans isolated from carious dentin before and after partial dentin caries removal (PDR) and sealing. Carious dentin samples were obtained three months before and after the PDR and cavity sealing. Up to seven isolates of each morphological type of S. mutans were selected and strain identity was co...

When a marine stern shaft is bent with shafting misalignment and stern bearing wear factors, etc., the sealing properties of a plane mechanical seal is declined with the increase of both contact pressure and temperature of sealing surface, so a spherical mechanical seal which can automatically adjust the contact state of sealing surfaces is proposed to replace the plane mechanical seal in order...

case presentation we present a case of a grade iii coronary perforation in which the double guiding catheter technique helped us to deliver the graft stent. conclusions the double-guiding technique is useful in emergency situations to increase the safety and efficacy of sealing a coronary perforation. introduction coronary vessel perforation is one of the most feared complications of coronary a...

The failure reasons of reciprocating sealing in OPI-1800AWS fracturing pump are analyzed by scanning electron microscope technology (SEMT). The lubrication mechanism of plunger seal friction pair is analyzed by hydrodynamic lubrication theory. During its discharge and suction stroke, the reciprocating sealing friction pair meets the conditions of hydrodynamic lubrication, a certain thickness of...
