The kinetics
of hydroperoxide formation was examined on the basis of previously proposed mechanisms and found to be of the half-order with respect to the concentration of conjugated diene hydroperoxide. The amounts of added antioxidants remaining in sunflower oil after different microwave heating periods at different temperatures were determined by HPLC-DAD. The results were interpreted in terms of antioxidative effects of carnosic acid and sesamol. Carnosic acid was found to be a more effective antioxidant find more than sesamol for sunflower oil.

“To establish whether a nurse-led urogynecology triage clinic (UTC) is effective in terms of patient journey (from primary referral to first hospital contact until discharge), diagnosis, management, and outcomes.
The case notes of 300 patients attending the UTC in a university hospital between
January 2006 and November 2007 were randomly selected for review.
The mean interval from referral to first visit AICAR PI3K/Akt/mTOR inhibitor improved from 15.6 weeks (range = 12-32 weeks) to 4.6 weeks (range = 1-11 weeks, SD = 1.97) after UTC. Compared to pre-UTC, the mean period from first visit to final outcome improved from 11 months (range = 3.0-23.0 months) to 8.8 weeks (range = < 1-60 weeks, SD = 11.15). Fifty-nine percent were discharged from the UTC without being seen by a specialist.
By service redesigning, the UTC has reduced the number of clinic visits and patient journey time and has also shown that the majority of women with incontinence can be adequately managed by a specialist nurse.”
“Lung metastasectomy is an area of interest and controversy in surgical oncology. Most of the available evidence derives from small cohorts with short follow-up. The aim of this study was to evaluate the oncologic outcomes in an 18-year cohort
from a single center. We retrospectively reviewed 398 patients this website with several malignancies who underwent lung metastasectomy between January 1990 and December 2008. Demographic, clinical, and surgical variables were evaluated. Uni- and multivariate analyses were performed to identify factors associated with overall survival (OS). Mean follow-up was 20 months. Wedge resection was performed in 297 cases and 101 required anatomic resections. In 303 patients the disease-free interval (DFI) was >6 months meanwhile 95 patients had a DFI <= 6 months. Complete resection was achieved in 351 patients (88.2%). Median OS for all patients was 81.9 months (95% CI, 36.9-126.9). On multivariate analysis, factors associated with a poor overall survival were DFI <6 months (HR, 1.74; 95% CI, 1.24-2.4; p = 0.001) and incomplete resection (HR, 1.58 95% CI, 1.01-2.5; p = 0.0047).
