Poor prognosis in cases was defined as any stage with Gleason sum 8-10, pT3A (if Gleason sum was greater than 7), pT3B or higher (all Gleason sums), any N1 or higher, any M1 or higher, or any documented PSA recurrence (biochemical failure). Single nucleotide polymorphisms were genotyped using allelic discrimination assays. Logistic regression models were used to estimate the OR with the corresponding 95% CI for individual racial/ethnic groups. Allelic frequency across ethnic/racial groups was compared using Pearson’s chi-square test.

Results: A total of 653 cases and 1,476 controls were genotyped at C-509T. The TT genotype showed a significant protective effect against high grade prostate cancer

(OR 0.482, 95% CI 0.274-0.849). In addition, the Caspase Inhibitor VI TT genotype was associated with a decreased risk of poor prognosis prostate cancer (OR 0.488, 95% CI 0.236-1.009). Limiting analysis to nonHispanic

white men showed that the TT genotype had an even more pronounced protective effect for poor prognosis prostate cancer (OR 0.297, 95% CI 0.100-0.887). Finally, there was a significant difference in the distribution of allelic frequency across racial/ethnic selleck products groups (p < 0.0001).

Conclusions: We observed an association between single nucleotide polymorphisms of TGFB1 at C-509T and a decreased risk of aggressive prostate cancer. The TT genotype of TGFB1 at C-509T demonstrates a protective effect against high grade prostate cancer and cases with poor prognosis.”
“OBJECTIVE: We sought to simulate the frontotemporal orbitozygomatic (FTOZ) craniotomy in a three-dimensional virtual environment on patient-specific data and to quantify the

Phenylethanolamine N-methyltransferase exposure afforded by the FTOZ while simulating controlled amounts of brain retraction.

METHODS: Four computed tomographic angiograms were reconstructed with commercially available software (Amira 4.1.1; Mercury Computer Systems, Inc., Chelmsford, MA), and virtual FTOZ craniotomies were performed bilaterally (n = 8). Brain retraction was simulated at 1 and 2 cm. Surgical freedom and projection angle were measured and compared at each stage of the FTOZ.

RESULTS: At 1 cm of retraction, surgical freedom increased by 27 +/- 14% for the removal of the orbital rim and by 31 +/- 18% for FTOZ (P < 0.01) when compared with frontotemporal (FT) craniotomy. At 2 cm of retraction, surgical freedom increased by 15 5% and 26 +/- 8% for the removal of the orbital rim and FTOZ, respectively (P < 0.01). With increased retraction, surgical freedom increased by 100 +/- 26%, 81 +/- 15%, and 82 +/- 27% for the FT, removal of the orbital rim, and FTOZ craniotomies, respectively (P < 0.001). Projection angle increased by 24.2% when orbital rim removal was added to the FT craniotomy (P < 0.01).

CONCLUSION: Surgical freedom increases significantly at every step of the FTOZ craniotomy. This effect is less robust when brain retraction is increased.
