Nordback J, Lundberg E (1999) High resolution separation of non-polar lipid classes by HPLC-ELSD using alumina as stationary phase. J High Resol Chromatogr 22:483-486Nordback, J., and Lundberg, E. 1999. High resolution separation of non- polar lipid classes by HPLC-ELSD using ...
through the distribution of the analytes between a stationary phase packed in a column and a liquid mobile phase that is pumped through the column. Traditionally, the stationary phase was polar, e.g., silica, and the mobile phases used were relatively non-polar. This HPLC mode is called[...
Electrospray ionisation (ESI), along with APCI—both compatible with liquid chromatography (LC)—have extended the chemical space in two ways; by including more polar, water-soluble and larger molecules and by providing more accurate and detailed data on the ionised molecule. High-resolution mass ...
In this study, while considering age, sex and proximal–distal variations, we used a multi-omics approach in non-human primates (Macaca fascicularis) to shed light on the heterogeneity of intestinal aging and identify potential regulators of gut aging. We explored the roles of several regulators,...
Subsequent research provided evidence that a common humoral factor may be responsible for inhibition of Na+, K+-ATPase and sodium transport. For example, numerous studies have supported the proposition that the inhibition of Na+, K+-ATPase in the smooth muscle of the arteriole increases intracellul...
polar functional group. These systems are then capable of copolymerizing ethylene and monomers of hydroxy- or carboxy-alpha-olefin type (for example: 10-undecen-1-ol). The copolymers obtained contain a maximum of 10 mol % of the polar monomer. In this case, the major drawback of the ...
2-Hydroxypropyl methacrylate was purchased from Sigma Aldrich and was purified by silica column chromatography, employing n-hexane:ethyl acetate 90:10. Urea (powder, BioReagent for molecular biology, suitable for cell culture) was purchased from Sigma Aldrich and recrystallized from ethanol. ...
tandem mass spectrometry (HRMS/MS), through to data evaluation and reporting in the context of NTS. Although most experience within the NORMAN network still involves water analysis of polar compounds using LC–HRMS/MS, other matrices (sediment, soil, biota, dust, air) and instrumentation (GC, ...
1B)22,23. PET imaging of tau aggregation in non-AD tauopathies has been limited to utilizing radiopharmaceuticals originally developed and optimized for imaging AD tau aggregates. For example, [18F]PI-2620 (Fig. 1A), a structural analogue of [18F]Tauvid, has been evaluated for human PET ...
For example, the receptor mutants R251:6.58 L and R276:7.39 F showed a potency decrease of more than 100-fold. The binding cavity of SUCNR1 is characterised by a polar network consisting of residues in TM-II (Y79:2.64), TM-III (R95:3.29), TM-VI (R248:6.55, R251:6.58),...
