An in silico MS/MS library for automatic annotation of novel FAHFA lipids. [PDF]

, 2015
BackgroundA new lipid class named 'fatty acid esters of hydroxyl fatty acids' (FAHFA) was recently discovered in mammalian adipose tissue and in blood plasma and some FAHFAs were found to be associated with type 2 diabetes.

Shaping electrospray plume with convergent sound beams

iScience
Summary: Electrospray ionization (ESI) is one of the mainstream ionization techniques for mass spectrometry (MS) nowadays. Here, we present a new variant of ESI-MS setup, in which an electrospray emitter points to the mass spectrometer’s orifice while ...

Levitated Spinning Graphene [PDF]

, 2010
A method is described for levitating micron-sized few layer graphene flakes in a quadrupole ion trap. Starting from a liquid suspension containing graphene, charged flakes are injected into the trap using the electrospray ionization technique and are ...

Lipidomics of cellular and secreted phospholipids from differentiated human fetal type II alveolar epithelial cells

Journal of Lipid Research, 2006
Maturation of fetal alveolar type II epithelial cells in utero is characterized by specific changes to lung surfactant phospholipids. Here, we quantified the effects of hormonal differentiation in vitro on the molecular specificity of cellular and ...

Simultaneous sampling of volatile and non-volatile analytes in beer for fast fingerprinting by extractive electrospray ionization mass spectrometry [PDF]

, 2018
By gently bubbling nitrogen gas through beer, an effervescent beverage, both volatile and non-volatile compounds can be simultaneously sampled in the form of aerosol.

Influence of the sebaceous gland density on the stratum corneum lipidome [PDF]

, 2018
The skin surface lipids (SSL) result from the blending of sebaceous and epidermal lipids, which derive from the sebaceous gland (SG) secretion and the permeability barrier of the stratum corneum (SC), respectively.

Identification of phosphatidylserylglutamate: a novel minor lipid in Escherichia coli

Journal of Lipid Research, 2009
Advances in mass spectrometry have facilitated the identification of novel lipid structures. In this work, we fractionated the lipids of Escherichia coli B and analyzed the fractions using negative-ion electrospray ionization mass spectrometry to reveal ...

Quantification of seminolipid by LC-ESI-MS/MS-multiple reaction monitoring: compensatory levels in Cgt mice[S]

Journal of Lipid Research, 2010
Seminolipid, also known as sulfogalactosylglycerolipid (SGG), plays important roles in male reproduction. Therefore, an accurate and sensitive method for SGG quantification in testes and sperm is needed.
