Raman microspectroscopy reveals unsaturation heterogeneity at the lipid droplet level and validates an in vitro model of bone marrow adipocyte subtypes

Olaia Maria Naveiras Torres-Quiroga, Josefine Catharina Pedersen Tratwal, Vasco Ledebur de Antas de Campos, Daniel Naveed Tavakol, Charles Christopher Bataclan

Bone marrow adipocytes (BMAds) constitute the most abundant stromal component of adult human bone marrow. Two subtypes of BMAds have been described, the more labile regulated adipocytes (rBMAds) and the more stable constitutive adipocytes (cBMAds), which d ...

Preferential retention of algal carbon in benthic invertebrates: Stable isotope and fatty acid evidence from an outdoor flume experiment

Tom Ian Battin

According to the River Continuum Concept, headwater streams are richer in allochthonous (e.g. terrestrial leaves) than autochthonous (e.g. algae) sources of organic matter for consumers. However, compared to algae, leaf litter is of lower food quality, par ...

Synergistic effect of carboxylic and amine ligands on the synthesis of CdSe nanocrystals

Martinus Adela Maria Gijs, Virendra Kumar Parashar

We demonstrate the drastic improvement in absorbance and photoluminescence (UV-PL) of CdSe nanocrystals (NCs) upon adding both a carboxylic acid and an amine ligand to the cadmium acetate green chemistry source. We combined carboxylate complexes of lauric ...

Dysregulation of soluble epoxide hydrolase and lipidomic profiles in anorexia nervosa

Pierre Magistretti, Jiangyan Yang

Individuals with anorexia nervosa (AN) restrict eating and become emaciated. They tend to have an aversion to foods rich in fat. Because epoxide hydrolase 2 (EPHX2) was identified as a novel AN susceptibility gene, and because its protein product, soluble ...

A rheostat mechanism governs the bifurcation of carbon flux in mycobacteria

Matteo Dal Peraro, John McKinney, Florence Pojer, Giulia Fonti, Paul Murima, Tarun Chopra

Fatty acid metabolism is an important feature of the pathogenicity of Mycobacterium tuberculosis during infection. Consumption of fatty acids requires regulation of carbon flux bifurcation between the oxidative TCA cycle and the glyoxylate shunt. In Escher ...
