Dry Deposition Strategies for MALDI–MS Imaging: Principles, Advances and Emerging Applications

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Matrix‐assisted laser desorption/ionisation mass spectrometry imaging (MALDI–MSI) has become a pivotal tool in biomedical research, enabling untargeted, spatially resolved analysis of molecular species in complex biological tissues. Among the critical steps in MALDI–MSI workflows, matrix deposition significantly influences sensitivity, spatial

Regulation of neutral cholesterol esterase activity by phospholipids containing negative charges in substrate liposome

open access: yesJournal of Lipid Research, 1995
The effect of phospholipids on cholesteryl ester hydrolysis by neutral cholesterol esterase in alveolar macrophages was studied. Among the phospholipids used as emulsifiers, those with a negative charge, such as phosphatidylserine, phosphatidic acid ...

High cholesterol absorption efficiency enhances proatherogenic properties of low‐density lipoprotein particles

open access: yesJournal of Internal Medicine, Volume 299, Issue 6, Page 711-725, June 2026.
Abstract Background and Aims High cholesterol absorption efficiency is determined by genetic variation in small intestinal sterol transporters and affects one‐third of individuals. Their risk for atherosclerotic cardiovascular disease (ASCVD) is increased compared with low cholesterol absorbers, despite similar serum lipid concentrations.

Cholesterol efflux from cells enriched with cholesteryl esters by incubation with hypercholesterolemic monkey low density lipoprotein

open access: yesJournal of Lipid Research, 1983
The mass efflux of free and esterified cholesterol was studied in skin fibroblasts loaded with cholesterol by incubation with low density lipoproteins (LDL) isolated from normal or hypercholesterolemic cynomolgus monkeys.

Cellular cholesteryl ester clearance. Relationship to the physical state of cholesteryl ester inclusions.

open access: yesJournal of Biological Chemistry, 1983
The hypothesis that clearance of cellular cholesteryl ester deposits may be a function of the physical state of the stored lipid has been investigated. Cultured rat hepatoma cells were induced to store cholesteryl ester in either anisotropic inclusions by exposure to free cholesterol-rich phospholipid dispersions or isotropic inclusions by exposure to ...

Metabolic Modulation Predicts Heart Failure Tests Performance [PDF]

open access: yes, 2019
The metabolic changes that accompany changes in Cardiopulmonary testing (CPET) and heart failure biomarkers (HFbio) are not well known. We undertook metabolomic and lipidomic phenotyping of a cohort of heart failure (HF) patients and utilized Multiple ...

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 2, Page 350-359, June 2026.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

Quantification and Localisation of New Brain Lipid Synthesis Using Deuterium Oxide and High Resolution Mass Spectrometry

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Liquid chromatography tandem mass spectrometry and mass spectrometry imaging were used in combination with deuterium oxide administration to quantify and localise newly synthesised myelin lipids in the mouse brain. This methodology, used here to show sites of myelin repair, enables the measurement of dynamic lipid synthesis in living systems and ...

Rapid method for determining cholesteryl ester transitions of apoB-containing lipoproteins.

open access: yesJournal of Lipid Research, 1982
A wide variety of cholesteryl ester-rich apoB-containing lipoproteins undergo an order-disorder transition in the cholesteryl ester core at approximately normal body temperature.
