Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

In this study, we compared the diagnostic performance of the standard SPECT with motion-frozen (MF) myocardial perfusion SPECT (MPS) in obese patients.', 'A total of 90 consecutive obese patients (body mass index, 30.1-46.8, average, 34.3 +/- 3.6; age, 63 +/- 12 y; 30% women) underwent standard supine rest (201)Tl/stress (99m)Tc dual-isotope gated MPS and cardiac catheterization within 3 mo. MF images were obtained by nonlinear warping of cardiac phases to the end-diastolic position. Total perfusion deficit (TPD) was obtained for summed (S-TPD) and motion-frozen (MF-TPD) datasets with sex-specific standard and MF normal limits.', 'The area under the receiver-operating-characteristic (ROC) curve for detection of coronary artery disease (CAD) by MF-TPD was significantly larger than that for S-TPD (0.93 +/- 0.25 vs. 0.88 +/- 0.32, P < 0.05). MF-TPD had higher specificity (77% vs. 55%, P < 0.05) and accuracy (89% vs. 80%, P < 0.05) than did S-TPD.

Ex Output:
Does motion-frozen myocardial perfusion SPECT improve detection of coronary artery disease in obese patients?

Previous studies have shown that Fructus Ligustri Lucide (FLL) can be used to anti-cancer. However, the mechanism by which FLL mediate this effect is unclear. In the present study, aqueous extracts of FLL induced cell apoptosis in human gastric carcinoma cell was investigated.', 'The cell viability was detected by the CCK8 assay. The cell apoptosis was assessed by annexin V-PI double-labeling staining and hoechst 33342 staining. The protein expression of cell cycle regulators and tumor suppressors were analyzed by western blotting.', 'Treatment of human gastric carcinoma cells with FLL induced cell death in a dose- and time-dependent manner by using CCK8 assay. Consistent with the CCK8 assay, the flow cytometry results showed that the proportion of the early and terminal phase of apoptosis cells had gained after FLL treatment as compared to untreated group. Moreover, human gastric carcinoma cells were exposed to the aqueous extracts of FLL for 48 h, which resulted in an accumulation of cells in G2/M phase. Apoptotic bodies were clearly observed in human gastric carcinoma that had been treated with FLL for 48 h and then stained with Hochest 33342. Treatment of gastric carcinoma cells with increasing doses of FLL and increasing durations significantly increased the protein expression of Bax and Caspase3, decreased the anti-apoptotic Bcl-2 level. The expression of CDC2 and cdc25C were downregulated upon FLL treatment in human gastric carcinoma. In contrast, p53 and p21 were obviously upregulated by FLL treatment in a concentration-dependent manner.

This study was done to identify nurses' priorities for continued learning and to examine the priorities in relation to age, educational level, location in the organization, experience, position in the organization, and shift worked.", "A random sample of nurses at a Veterans Affairs Medical Center completed surveys consisting of 58 educational topics and demographic information. The results were analyzed using descriptive statistics, analysis of variance, and Tukey's HSD method to identify differences within the various subgroups of nurses.", 'Of the 58 educational topics, 21 were determined to be high priority educational needs and were significantly correlated with one or more of the independent variables.

Ex Output:

Does continuing education need assessment of acute care and long-term-care nurses in a Veterans Affairs Medical Center?
