(Table 1) Description of structures in cores at DSDP Holes 59-451, 59-448A and 59-447A

Fifteen lengths of Leg 59 cores (primarily from Hole 451 as well as from Holes 447A and 448A) exhibiting macroscopic faults were selected by Dr. R. B. Scott (Co-Chief Scientist, Leg 59) to help us initiate this petrofabric analysis. We proposed to (1) determine what dynamically useful deformation features might be associated with the faults, and (2) infer from these features as much as possible about the physical environment of the deformation (effective pressure, differential stress, temperature, and strain rate), the orientation and relatively magnitudes of the principal stresses at the time of deformation, and the degree of induration of the rocks at the time of deformation. The cores, mainly from Hole 451, had been slabbed on board ship with respect to the trace of bedding so that each cut surface contains the true bedding dip-direction. In general, the cores from Hole 451 are largely calcareous, lithic and vitric, brecciated tuffs, whereas those from Holes 447A and 448A are basalts or basalt breccias.

Effectiveness of medical abortion with mifepristone and buccal misoprostol through 59 gestational days

BACKGROUND: From 2001 to March 2006, Planned Parenthood Federation of America (Planned Parenthood) health centers throughout the United States provided medical abortions principally by a regimen of oral mifepristone, followed 24-48 h later by vaginal misoprostol. In late March 2006, analyses of serious uterine infections following medical abortions led Planned Parenthood to change the route of misoprostol administration and to employ additional measures to minimize subsequent serious uterine infections. In August 2006, we conducted an extensive audit of medical abortions with the new buccal misoprostol regimen so that patients could be given accurate information about the success rate of the new regimen. OBJECTIVES: We sought to evaluate the effectiveness of the buccal medical abortion regimen and to examine correlates of its success during routine service delivery. METHODS: In 2006, audits were conducted in 10 large urban service points to estimate the success rates of the buccal regimen. Success was defined as medical abortion without vacuum aspiration. These audits also permitted estimates of success rates with oral misoprostol following mifepristone in a subset in which 98% of the subjects stemmed from two sites. RESULTS: The effectiveness of the buccal misoprostol-mifepristone regimen was 98.3% for women with gestational ages below 60 days. The oral misoprostol-mifepristone regimen, used by 278 women with a gestational age below 50 days, had a success rate of 96.8%. CONCLUSION: In conjunction with 200 mg of mifepristone, use of 800 mcg of buccal misoprostol up to 59 days of gestation is as effective as the use of 800 mcg of vaginal misoprostol up to 63 days of gestation.
