Novel MRI contrast methods, such as Chemical Exchange Saturation Transfer (CEST), rely on previously developed theory and approaches, often introduced first Notepads in solidstate NMR.Understanding or at least connecting the basic principles and original works to the modern-day contrast methods in MRI is instructive.The work brings together concept
Abstract Background Livestock fascioliasis is a problem throughout Ecuador, Colombia and Venezuela, mainly in Andean areas where the disease also appears to affect humans.Transmission patterns and epidemiological scenarios of liver fluke infection have shown to differ according to the lymnaeid vector snail species involved.These Andean countries pr
Activity-guided separation of antioxidant response element (ARE)-inducing constituents VIT A FACIAL SCRUB from the rhizomes of Atractylodis Rhizoma Alba was performed by the combination of centrifugal partition chromatography (CPC) and an ARE luciferase reporter assay.From 3 g of the active n-hexane fraction, one polyacetylene, (6E,12E)-tetradeca-6
The tribological performance of organic molybdenum in the present of organic friction modifier was investigated in this study.Three types of organic friction modifiers were selected, which are Glycerol monooleate, Pentaerythritol and N,N-Dimethylhexadecylamine.The organic Schisandra molybdenum are MoDTC, MoDDP and molybdenum amide.Friction coeffici
