The LockDown device (previously called Surgilig) is a braided polyester mesh which is mostly used to reconstruct the dislocated acromioclavicular joint. More than 11,000 have been implanted worldwide. Little is known about the tissue reaction to the device nor to its wear products when implanted in an extra-articular site in humans. This is of importance as(More)
The authors produced various degradation products of human hemoglobin. With the aid of immune sera raised against native hemoglobin and their fragments, we examined the antigenicity of the intact molecule and fragments as well as the specificity and reactivity of the immune sera used. Since conventional guaiac-type reactions make no distinction between the(More)
A method is presented for the routine analysis of amphetamine, methamphetamine, and related compounds in urine with gas chromatography coupled with mass spectrometry operated in the selective ion monitoring mode. The analytes are isolated by liquid-liquid extraction and are derivatized with trifluoroacetic anhydride. 3,4-Methylenedioxy-methamphetamine-D(5)(More)
Immunoselection screening methods were developed for the detection of the free heavy chain determinants of biological fluids. The optimal sensitivity range of the electrosyneresis and electroimmunoassay type methods lies between 400 ng and 2 micrograms/ml and between 3 micrograms and 1 mg/ml for immunoglobulins. The sensitive, relatively rapid and cheap(More)
AIMS Glenoid bone loss can be a challenging problem when revising a shoulder arthroplasty. Precise pre-operative planning based on plain radiographs or CT scans is essential. We have investigated a new radiological classification system to describe the degree of medialisation of the bony glenoid and that will indicate the amount of bone potentially(More)
The authors describe a modified version of counterimmunoelectrophoresis of easy performance and high sensitivity. With this method human haemoglobin can easily and specifically be determined either in fresh or dried biological samples. Glutaraldehyde pretreatment of the samples results in the development of complexes with highly favourable electrophoretic(More)
