SAI patients were compared with 27 previous patients who had pelvic fixation via other screw techniques.

Results. For SAI fixation, correction of pelvic obliquity and Cobb angles were 20 degrees +/- 11 degrees (70%) and 42 degrees +/- 25 degrees (67%), respectively. For other pelvic fixation methods, those values were 10 degrees +/- 9 degrees (50%), and 46 degrees +/- 16 degrees (60%),

respectively. Compared high throughput screening compounds with other screws, SAI screws provided significantly better pelvic obliquity correction (P = 0.002) but no difference in Cobb correction. There were 2 lucencies adjacent to screws in both groups. Computed tomography scans of 18 SAI patients showed no intrapelvic protrusion, but 1 screw extended laterally (<5 mm). One early SAI patient required revision with larger screws, which relieved pain; there was 1 revision in the comparison group. SAI patients had no deep infections, implant prominence, late skin breakdown,

or anchor migration; traditional patients had 3 deep infections (P = 0.09) Bcl-2 inhibitor and 3 instances of implant prominence, skin breakdown, or anchor migration.

Conclusion. SAI pelvic fixation produces better correction of pelvic obliquity than do previous techniques. Radiographic and clinical anchor stability is satisfactory at 2-year follow-up.”
“Microporous polyvinylidene fluoride (PVDF) membrane was prepared via thermally induced phase separation (TIPS) method using a binary diluent of diphenyl ketone (DPK) and 1,2-propylene glycol (PG). The phase diagram for the PVDF/binary diluent of DPK and PG system was measured in the range of the PG/DPK mass ratio changing from 0 to 2/3. Then the effects of the

PG/DPK mass ratio and the PVDF concentration on membrane cross-section structures and tensile strength were also investigated. The results showed that the addition of PG brought about a shift Vactosertib TGF-beta/Smad inhibitor of the cloud point curve to a higher temperature and the extension of the liquid-liquid phase separation region to a higher polymer concentration. Therefore a bicontinuous cross-section structure was obtained when the PG/DPK mass ratio was 3/7 and the polymer concentration was 30 wt %. As an increase of the PG/DPK mass ratio, the tensile strength increased gradually at a fixed PVDF concentration. Moreover, for the same PG/DPK mass ratio, the cross-section microstructure changed from a bicontinuous or a cellular structure to a spherulitic structure, and the tensile strength increased drastically as the polymer concentration increased from 20 to 50 wt (C) 2010 Wiley Periodicals, Inc.
