Amide Proton Transfer Weighted Imaging Shows Differences in Multiple Sclerosis Lesions and White Matter Hyperintensities of Presumed Vascular Origin

Objectives: To assess the ability of 3D amide proton transfer weighted (APTw) imaging based on magnetization transfer analysis to discriminate between multiple sclerosis lesions (MSL) and white matter hyperintensities of presumed vascular origin (WMH) and to compare APTw signal intensity of healthy white matter (healthy WM) with APTw signal intensity of MSL and WHM. Materials and Methods: A total of 27 patients (16 female, 11 males, mean age 39.6 years) with multiple sclerosis, 35 patients (17 females, 18 males, mean age 66.6 years) with small vessel disease (SVD) and 20 healthy young volunteers (9 females, 11 males, mean age 29 years) were included in the MSL, the WMH, and the healthy WM group. MSL and WMH were segmented on fluid attenuated inversion recovery (FLAIR) images underlaid onto APTw images. Histogram parameters (mean, median, 10th, 25th, 75th, 90th percentile) were calculated. Mean APTw signal intensity values in healthy WM were defined by Region of interest (ROI) measurements. Wilcoxon rank sum tests and receiver operating characteristics (ROC) curve analyses of clustered data were applied. Results: All histogram parameters except the 75 and 90th percentile were significantly different between MSL and WMH (p = 0.018-p = 0.034). MSL presented with higher median values in all parameters. The histogram parameters offered only low diagnostic performance in discriminating between MSL and WMH. The 10th percentile yielded the highest diagnostic performance with an AUC of 0.6245 (95% CI: [0.532, 0.717]). Mean APTw signal intensity values of MSL were significantly higher than mean values of healthy WM (p = 0.005). The mean values of WMH did not differ significantly from the values of healthy WM (p = 0.345). Conclusions: We found significant differences in APTw signal intensity, based on straightforward magnetization transfer analysis, between MSL and WMH and between MSL and healthy WM. Low AUC values from ROC analyses, however, suggest that it may be challenging to determine type of lesion with APTw imaging. More advanced analysis of the APT CEST signal may be helpful for further differentiation of MSL and WMH.

Development of an analytical methodology for the analysis of priority cytostatics in water

The consumption of cytostatics has remarkably increased over the last years due to the high cancer incidence worldwide. In previous studies, seven cytostatics were already recognized to potentially induce chronic effects in aquatic organisms, taking into account their estimated concentrations in surface waters: cyclophosphamide (CYC), capecitabine (CAP), mycophenolic acid (MPA), imatinib (IMA), bicalutamide (BICA), prednisone (PRED) and 5-fluorouracil (5FU). The objective of the present study was to simultaneously analyse these 7 prioritized compounds, which have the highest chances to be found in surface and wastewaters. The analytical challenge relies in the determination of these very polar compounds, which have different chemical and structural properties. Solid-phase extraction with an Ultra Performance Liquid Chromatograph-Mass Spectrometer in electrospray ionization mixed mode (5-fluorouracil and bicalutamide in negative mode and the others in positive one) was developed to determine seven cytostatics in wastewater and surface water. Among eight tested cartridges with different sorbents and conditions, the best extraction performance was attained with Oasis WAX at pH 10, with recoveries ranging from 31 +/- 4 (5FU) and 103 +/- 17% (MPA). Regarding the chromatographic analysis, the best results were achieved with an XBridge amide column. The final analytical methodology was successfully applied for the analysis of real water samples, confirming the presence of risky cytostatics in surface and wastewaters. (c) 2018 Elsevier B.V.

General procedure: The following experimental procedure for the chemoselective partial reduction of ethyl benzoate and N,N-dimethyl 3-toluamide is representative. A dry and argon-flushed flask, equipped with a magnetic stirring bar and a septum, was charged with ethyl benzoate (0.07mL, 0.5mmol), N,N-dimethyl 3-toluamide (0.08mL, 0.5mmol) and 5mL THF. After CDBBA (9.01mL, 0.44M soln. 4.0mmol) was slowly added and stirred for 12h at room temperature. The reaction was quenched by aqueous 1N HCl (10mL) and extracted with diethyl ether (2¡Á10mL). The combined organic layers were dried over MgSO4. GC analysis showed a 97% recovery yield of ethyl benzoate and 95% yield of 3-methylbenzaldehyde. All products in Table 2 were confirmed through comparison with GC data of authentic sample.

Lambda/,Lambda/-Dimethylhexanamide (1.5g, 10.6mmol) was slowly added to an initially stirred mixture of phosphorus trichloride (2.8ml, 32.2mmol) and phosphorous acid (1.15g, 14.0mmol). The mixture was heated at 7O0C for 2h. After cooling the excess phosphorous trichloride was decanted off and the residue hydrolyzed by the careful addition of plenty of water. This mixture was left to stir for at least 2h, filtered, and the filtrate evaporated to dryness under reduced pressure.
