Population and decay of a Kπ=8- two-quasineutron isomer in Pu 244

The decay of a Kπ=8- isomer in Pu244 and the collective band structures populating the isomer were studied using deep inelastic excitations with Ti47 and Pb208 beams, respectively. Precise measurements of M1/E2 branching ratios in the band confirm a 9/2-[734]ν - 7/2+[624]ν configuration assignment for the isomer, validating the systematics of Kπ=8-, two-quasineutron isomers observed in even-Z, N=150 isotones. These isomers around the deformed shell gap at N=152 provide critical benchmarks for theoretical predictions of single-particle energies in this gateway region to superheavy nuclei

The Cholecystectomy As A Day Case (CAAD) Score: A Validated Score of Preoperative Predictors of Successful Day-Case Cholecystectomy Using the CholeS Data Set

Background Day-case surgery is associated with significant patient and cost benefits. However, only 43% of cholecystectomy patients are discharged home the same day. One hypothesis is day-case cholecystectomy rates, defined as patients discharged the same day as their operation, may be improved by better assessment of patients using standard preoperative variables. Methods Data were extracted from a prospectively collected data set of cholecystectomy patients from 166 UK and Irish hospitals (CholeS). Cholecystectomies performed as elective procedures were divided into main (75%) and validation (25%) data sets. Preoperative predictors were identified, and a risk score of failed day case was devised using multivariate logistic regression. Receiver operating curve analysis was used to validate the score in the validation data set. Results Of the 7426 elective cholecystectomies performed, 49% of these were discharged home the same day. Same-day discharge following cholecystectomy was less likely with older patients (OR 0.18, 95% CI 0.15–0.23), higher ASA scores (OR 0.19, 95% CI 0.15–0.23), complicated cholelithiasis (OR 0.38, 95% CI 0.31 to 0.48), male gender (OR 0.66, 95% CI 0.58–0.74), previous acute gallstone-related admissions (OR 0.54, 95% CI 0.48–0.60) and preoperative endoscopic intervention (OR 0.40, 95% CI 0.34–0.47). The CAAD score was developed using these variables. When applied to the validation subgroup, a CAAD score of ≤5 was associated with 80.8% successful day-case cholecystectomy compared with 19.2% associated with a CAAD score >5 (p < 0.001). Conclusions The CAAD score which utilises data readily available from clinic letters and electronic sources can predict same-day discharges following cholecystectomy

Macroline, akuammiline, sarpagine, and ajmaline alkaloids from Alstonia macrophylla

A total of seventeen alkaloids, comprising six macroline (including alstofolinine A, a macroline indole incorporating a butyrolactone ring-E), two ajmaline, one sarpagine, and eight akuammiline alkaloids, were isolated from the stem-bark and leaf extracts of the Malayan Alstonia macrophylla. The structure and relative configurations of these alkaloids were established using NMR, MS and in several instances, confirmed by X-ray diffraction analysis. Six of these alkaloids were effective in reversing multidrug-resistance(MDR) in vincristine-resistant KB cells

Continuing professional development--global perspectives: synopsis of a workshop held during the International Association of Dental Research meeting in Gothenburg, Sweden, 2003. Part 2: regulatory and accreditation systems and evidence for improving the performance of the dental team.

Item does not contain fulltextThis paper is the second in a series of two that report on continuing professional development (CPD). Details of the informants and the methodologies used were reported in the first paper. This paper reports the data and information presented on the topics of regulatory and accreditation systems for CPD and evidence that CPD improves the performance of the oral health team. By June 2003, participation in CPD was mandatory in most of the states of the USA, all Canadian Provinces, the UK and Latvia and was likely to become mandatory in a number of other countries in the near future. A variety of accreditation systems were reported including collecting CPD points, which in some countries were weighted depending on the type of CPD activity, and re-certification examinations. Very few studies for the effectiveness of dental CPD were identified. However, in general it was concluded that there is little evidence for the effectiveness of CPD for the oral health team. The main recommendation from this study is that a systematic review of the effectiveness of CPD in improving the performance of the oral health team and patient based outcomes be undertaken. A range of other research questions was also identified including: how can CPD be best matched to clinicians' needs rather than demands
