“The ITF2357 phenolic beads (PB) in macrosize
range were obtained by mixing phenol and formaldehyde in the presence of basic catalyst by suspension polymerization. In this reaction, the triethylamine (TEA), poly(vinyl alcohol), and hexamethylenetetramine (HMTA) were used as initiator, stabilizer, and crosslinking agent, respectively. The resulting PB within size range 0.1-2.0 mm was obtained in this polymerization reaction, carried Out at temperature 96 degrees C +/- 1 degrees C with agitation rate 475 rpm for 4 h. The effects of different variables Such as, formaldehyde to phenol ratio (F/P) by mole, initiator concentration, concentration of crosslinking agent, and temperature on the particle sizes of PB and its formation were investigated. The particle size and its distribution were shown to be dependent on the F/P ratio, initiator concentration, and temperature. The average particle size of PB increased with increasing F/P ratio by mole in the reaction mixture. The average particle size of PB decreased
with increasing TEA concentration. The Selleckchem XMU-MP-1 particle size distribution of PB became narrow in size range 0.9-1.3 mm with 86% of yield of 1.0% by weight. As far as the crosslinking is concerned, the uncured phenolic resin was formed in the reaction solution when the reaction was performed in the absence of HMTA at 96 degrees C +/- 1 degrees C for 4 h. The amount Cured PB formed increased with increase in the concentration of HMTA. selleck inhibitor The surface morphology, shape and size of PB were studied using scanning electron microscopy.

“Background: Although the results of the Latarjet procedure have been reported previously, there is little literature regarding the early complications of this procedure. The purpose of this study was to report
our experience with the Latarjet procedure for glenohumeral instability and to highlight the initial complications that may occur following this procedure.
Methods: Forty-seven patients (forty-eight shoulders) underwent the Latarjet procedure for anterior glenohumeral instability between January 2005 and January 2010. All shoulders had some osseous deficiency of the anterior glenoid rim or had undergone an unsuccessful prior soft-tissue Bankart repair. The minimum duration of patient follow-up was six months.
Results: Forty-five shoulders were available for follow-up. The overall complication rate was 25% (twelve of the original forty-eight shoulders). Complications were divided into three groups: infection, recurrent glenohumeral instability, and neurologic injury. A superficial infection developed in three shoulders (6%); in all cases, the infection resolved following irrigation and debridement and administration of antibiotics for up to four weeks.
