The bonding strength between bone and alpha-2-cyanoacrylate polymers, with or without the addition of powdered hydroxyapatite, was determined. The tensile strength of a bone-cyanoacrylate bond was measured for each polymer: 4.31 +/- 0.88 MPa (methyl-), 5.74 +/- 0.62 MPa (ethyl-), and 8.33 +/- 0.41 MPa (isobutyl-). The tensile strength of the isobutyl-2-cyanoacrylate bond increased to 12.03 +/- ...

damage and fistula formation are known to occur (13). Formation of spinal arteriovenous fistulas (AVF) also has been reported as a delayed complication developing after lumbar surgery (3). We experienced spinal dural/epidural AVFs that developed at the site of previous lumbar surgery and successfully treated it with n-butyl cyanoacrylate (Histoacryl, B.Braun, Melsungen, Germany). To our knowled...

Microscale pumps that are simultaneously capable of turning “on” in response to specific analytes in solution and of providing precise control over flow rate will be needed for certain types of smart microand nanoscale devices. Access to these types of pumps, however, has remained limited. Two general approaches for designing microscale pumps have been proposed: 1) those that are turned on and ...

The aim of this study was to evaluate the influence of a low-viscosity bonding resin applied over a self-etching adhesive system on the microtensile bond strength (microTBS) of indirect restorations. Comparisons were made using One Up Bond F (OB) self-etching adhesive system, Single Bond (SB) one-bottle adhesive system and Scotchbond Multi Purpose Plus (SMP) bonding component. Thirty bovine inc...

DEAR EDITOR Cyanoacrylates (CAs) were first described in 1949 and their potential as adhesives were quickly recognised.1 Various homologues of CA adhesive have been studied and used, including methyl-, ethyl-, isobutyl-, isohexyl-, and octyl-CA.1 Commercial CA now has widespread use as an all purpose adhesive in various industries, however the main application of CA is as adhesives domestically...

Intravital microscopy of mouse calvarial bone marrow (BM) is a powerful method for studying hematopoietic stem cells (HSCs) and the BM microenvironment at the cellular level. However, the current method used to access the mouse calvaria allows for only a few imaging times in the same mouse because of scar formation and inflammation induced by multiple surgeries. Longitudinal imaging of the BM m...

During a 4 year period, 48 patients were treated with balloon catheters. There were 39 fistulas and nine aneurysms. Detachable balloons with a modified Debrun technique were used in 37 patients. Different kinds of technical problems were encountered. The arterial axis remained patent in 29 of the 37 fistulas; in the two mixed internal and external carotid-cavernous sinus fistulas, combined embo...

OBJECTIVE To improve the efficacy of intratympanic therapy using perilymphatic entry through the round window membrane. MATERIAL AND METHODS The perilymphatic entry characteristics of 2 neutral molecules, mannitol (182.2 Da) and inulin (7,000 Da), were studied. A polyethylene catheter was placed in contact with the guinea pig round window membrane and sealed with cyanoacrylate glue. This cath...

Atopic dermatitis skin tends to be easily irritated and appears dry. These clinical peculiarities correspond to impaired barrier function and to increased transepidermal water loss (TEWL) values. A few studies suggest that a reduced amount of total ceramides (especially of ceramide 1) is responsible for functional abnormalities of the skin of atopic dermatitis patients. The aim of this study wa...

We report a case of embolism of the sclerosant dye with subsequent formation of foreign-body giant cell reaction within the veins of pulmonary and portal circulation in an autopsy case of hepatocellular carcinoma developing over an underlying primary biliary cirrhosis.
