Comparison of platelet glass bead retention techniques in patients with clinical bleeding disorders.
Platelet glass bead retention by the Salzman and infusion pump techniques were compared in 36 control individuals, 10 patients with von Willebrand's syndrome and four patients with thrombocytopathies. No significant differences between the results of the two assays were observed. Eleven percent or less of the control individuals had diminished platelet glass bead retention. The mean percentage ...
متن کاملRetention of platelets by glass bead filters.
Whole blood was passed through glass bead filters and the retention of platelets studied under various experimental conditions. Platelet retention was similar over a wide range of blood flow rates; however, it was decreased at fast rates of flow. Platelet retention was not influenced by the haematocrit value of the blood over a wide range. Retention in filters containing siliconized beads was s...
متن کاملGlass Bead Calorimeter and Fiber Optic Readout
Large volume calorimeters are traditionally based on construction from high-density material or a “sandwich” construction of alternating layers of active and passive material. Dense scintillating material, made from materials such as BGO or lead-glass, is too costly to be used on a very large scale. In sandwich technology, energy resolution is often reduced due to a large fraction of the signal...
متن کاملDosimetric Characterisation of Glass Bead TLDs in Proton Beams
The Scanditronix MC40 variable energy cyclotron at the University of Birmingham is perhaps the most flexible research cyclotron in the country. Its extracted beam facilities are well used for isotope production, surface activation / wear and materials damage studies. Over the least 5 years a capability for radiobiology and dosimetry studies has been developed which enables use of the available ...
متن کاملReliability of Glass Bead Sterilization for Tried-in Orthodontic Bands
Materials and methods: A total of 68 molar bands were tried-in mouth of 17 patients. After try-in, 60 bands were cleaned in ultrasonic cleaning bath and then were equally divided into two groups (n = 30). Bands from group 1 were autoclaved in benchtop autoclave. Bands from group 2 were sterilized in glass bead sterilizer. After sterilization, the bands from both the groups were incubated in 50 ...
