We present a case of endoscopically unmanageable hemorrhagic diverticulum in the ascending duodenum. The ventral and dorsal walls of the ascending duodenum were supplied from the first jejunal artery (1JA) and inferior pancreaticoduodenal artery (IPDA), respectively. The hemorrhage mainly occurred from IPDA. The abruptly branching of IPDA from superior mesenteric artery enabled successful cathe...

OBJECTIVE To evaluate the clinical efficacy and safety of transcatheter arterial embolization (TAE) with N-Butyl Cyanoacrylate (NBCA) for nonvariceal upper gastrointestinal bleeding. MATERIALS AND METHODS Between March 1999 and December 2002, TAE for nonvariceal upper gastrointestinal bleeding was performed in 93 patients. The endoscopic approach had failed or was discarded as an approach for...

BACKGROUND Comminuted fractures can occur due to severe traumas. The treatment of these fractures that may cause serious morbidity and sometimes mortality is N-butyl cyanoacrylate. It has been reported that this adhesive provides sufficient rigid fixation for bone healing. This study aims to examine cyanoacrylate radiologically and histologically to determine whether it provides adequate recove...

Increasing attention has been devoted to the design of layered double hydroxide (LDH)-based hybrid materials. In this work, we demonstrate the intercalation by anion exchange process of poly(acrylic acid) (PAA) and three different hydrophilic random copolymers of acrylic acid (AA) and n-butyl acrylate (BA) with molar masses ranging from 2000 to 4200 g mol-1 synthesized by reversible addition-fr...

Subunit influenza vaccines have the advantage of purity and a broad dosage range. Clinical studies were done with a new subunit vaccine produced by detergent fractionation with tri-(n-butyl) phosphate (TNBP). Acceptability by the recipients was compared in volunteers given 400 CCA units of A2 and 300 of B Influenza vaccine as either Sharples, zonal centrifuged, ether subunit, or TNBP subunit bi...

AIM To present first experience of the use N-butyl cyanoacrylate with metacryloxisulfolane (Glubran 2) synthetic surgical glue, in the nonsurgical closure of oroantral communication (OAC). MATERIAL AND METHODS Two OACs, created after the exodontia of tooth 27 in 2 female patients, were sealed and closed with Glubran 2 surgical glue and monitored OACs, until the epithelization of the sockets w...

This paper describes the application of Raman spectroscopy to the detection of exogenous substances in cyanoacrylate-fumed fingerprints. The scenario considered was that of an individual handling a substance and subsequently depositing a contaminated fingerprint. These fingerprints were enhanced by cyanoacrylate fuming, a process in which a layer of white cyanoacrylate polymer is deposited on t...

The title compounds, rac-(1'R,2R)-tert-butyl 2-(1'-hydroxyethyl)-3-(2-nitrophenyl)-5-oxo-2,5-dihydro-1H-pyrrole-1-carboxylate, C(17)H(20)N(2)O(6), (I), rac-(1'S,2R)-tert-butyl 2-[1'-hydroxy-3'-(methoxycarbonyl)propyl]-3-(2-nitrophenyl)-5-oxo-2,5-dihydro-1H-pyrrole-1-carboxylate, C(20)H(24)N(2)O(8), (II), and rac-(1'S,2R)-tert-butyl 2-(4'-bromo-1'-hydroxybutyl)-5-oxo-2,5-dihydro-1H-pyrrole-1-car...

Both vacuum metal deposition (VMD) and cyanoacrylate fuming (CAF) are techniques used to visualise latent fingermarks on smooth non-porous surfaces such as plastic and glass. VMD was initially investigated in the 1970s as to its effectiveness for visualising prints on fabrics, but was abandoned when radioactive sulphur dioxide was found to be more effective. However, interest in VMD was resurre...

High solids content film-forming poly[styrene-co-(n-butyl acrylate)] [poly(Sty-co-BuA)] latexes armored with Laponite clay platelets have been synthesized by soap-free emulsion copolymerization of styrene and n-butyl acrylate. The polymerizations were performed in batch in the presence of Laponite and a methyl ether acrylate-terminated poly(ethylene glycol) macromonomer in order to promote poly...
