Article Title: Urothelial Urinary Bladder Cancer Is Characterized by Stage-Dependent Aberrations in Metabolism of Bioactive Sphingolipids
Article Snippet: An aliquot of the lipid extract was transferred to a fresh tube with pre-added N-palmitoyl-D-erythro-sphingosine (C17 base) (Avanti Polar Lipids) as an internal standard, and then subjected to alkaline hydrolysis to deacylate ceramide and dihydroceramide to free sphingosine and dihydrosphingosine, respectively.

Article Title: Quasi-Simultaneous Identification of Polar and Neutral Lipids in Mass Spectrometry by kHz Switching of Electrospray and Plasma Ionization.
Article Snippet: The identification of polar and neutral lipid species as biomarkers in complex biological samples is a key task in clinical and life sciences.. Electrospray and plasma-based ionization techniques are necessary to cover the full range of lipidomes, owing to their limited molecular polarity ranges.. However, combining both to generate hybrid spectra is difficult without averaging spectra, as electrospray and plasma sources operate under vastly different conditions.

Article Title: Elucidating the role of lipid interactions in stabilizing the membrane protein KcsA.
Article Snippet: The significant effects of lipid binding on the functionality of potassium channel KcsA have been validated by brilliant studies.. However, the specific interactions between lipids and KcsA, such as binding parameters for each binding event, have not been fully elucidated.. In this study, we employed native mass spectrometry to investigate the binding of lipids to KcsA and their effects on the channel.

(A) Membrane fusion of TatABC proteoliposomes with MPIase liposomes enabled the detection of the SufI translocation. INV, prepared from BL21/pT7-TatABC, were solubilized with OG, and then mixed with purified F 0 F 1 -ATPase. The proteoliposomes were then formed by removing the detergent. PL/DAG liposomes or PL/DAG/MPIase liposomes were fused to the reconstituted proteoliposomes. SufI translocation was performed co-translationally (left) or post-translationally (right) in the presence of these proteoliposomes. SufI(RR) (top left) or SufI(KK) (bottom left) was used as the substrate. One-ninth of the reaction mixture was analyzed as the translation standard (-) for the co-translational reactions.
