Use of yttrium 90 in persistent synovitis of the knee. II. Direct comparison of yttrium colloid resin and yttrium citrate.
The choice of radiocolloid for intra-articular therapy depends largely on factors of efficacy and safety. The fl-emission from yttrium 90 (90 Y) has a satisfactory range for use in the knee and a short half-life as well as freedom from gamma-radiation and from contamination. Since the demonstration by Stevenson, Bedford, Hill, and Hill (1971) and Stevenson and 12 others (1973) that chromosomal ...
متن کاملPreparation and photoluminescence of yttrium hydroxide and yttrium oxide doped with europium nanowires
Single-crystalline Y(OH)3:Eu nanowires have been prepared by polymer-assisted hydrothermal method. The yields of the nanowires were higher than 95%. XRD patterns showed that the products were the hexagonal Y(OH)3 structure. SEM images displayed that the nanowires consisted of nanobelts and nanorods. The nanorods have the diameter of about 85 nm and length up to several tens of microns, and the ...
متن کاملPreparation of yttrium metal by reduction of yttrium trifluoride with calcium
The preparation of yttrium metal by the reduction of yttrium trifluoride with calcium is described. Alternate methods employing the formation of a low melting Y-Zn or Y-Mg intermediate alloy are evaluated and data on chemical and microscopic purity of the resulting metal are presented.
متن کاملEffectiveness of Sodium Picosulfate/Magnesium Citrate (PICO) for Colonoscopy Preparation
PURPOSE Bowel preparation with sodium phosphate was recently prohibited by the U.S. Food and Drug Administration. Polyethylene glycol (PEG) is safe and effective; however, it is difficult to drink. To identify an easy bowel preparation method for colonoscopy, we evaluated three different bowel preparation regimens regarding their efficacy and patient satisfaction. METHODS In this randomized, ...
متن کاملThe Conversion of Human Prothrombin to Thrombin by Sodium Citrate. Analysis by Sodium Citrate. Analysis of the Activation Mixture.
Since the discovery that bovine prothrombin when dissolved in 25% sodium citrate is autocatalytically converted to thrombin (2), several reviews have appeared which summarize the many chemical and biological changes occurring during this transformation (3-5). Recently the findings that poly-L-lysine, as well as a number of polyamino acids, initiates prothrombin activation (6) have suggested the...
