Mboat7 down-regulation by hyper-insulinemia induces fat accumulation in hepatocytes.
2020
Background: Naturally occurring variation in Membrane-bound O-acyltransferase domain-containing 7 (MBOAT7), encoding for an enzyme involved in phosphatidylinositol acyl-chain remodelling, has been associated with fatty liver and hepatic disorders. Here, we examined the relationship between hepatic Mboat7 down-regulation and fat accumulation. Methods: Hepatic MBOAT7 expression was surveyed in 119 obese individuals and in experimental models. MBOAT7 was acutely silenced by antisense oligonucleotides in C57Bl/6 mice, and by CRISPR/Cas9 in HepG2 hepatocytes. Findings: In obese individuals, hepatic MBOAT7 mRNA decreased from normal liver to steatohepatitis, independently of diabetes, inflammatio…
Use of triacylglycerol profiles established by high performance liquid chromatography with ultraviolet–visible detection to predict the botanical ori…
2011
A method for the determination of triacylglycerols (TAGs) in vegetable oils from different botanical origins by HPLC with UV–vis detection has been developed. Using a core-shell particle packed column (C18, 2.6 micron), TAG separation was optimized in terms of mobile phase composition and column temperature. Using isocratic elution with acetonitrile/n-pentanol at 10 °C, excellent efficiency with good resolution between most of the TAG peak pairs, within a total analysis time of 15 min, was achieved. Using mass spectrometry detection, a total of 15 peaks, which were common to oils of six different botanical origins (corn, extra virgin olive, grapeseed, hazelnut, peanut and soybean) were iden…
Effect of a 1-year elastic band resistance exercise program on cardiovascular risk profile in postmenopausal women
2018
Objective: The aim of this study was to investigate the effects of a 1-year progressive resistance training program using elastic bands on cardiovascular profile parameters in sedentary postmenopausal (>12 months’ amenorrhea) women. Methods: This longitudinal prospective experimental study included 38 menopausal women who were randomly divided into two groups: an intervention group (IG, n = 18), who completed a progressive resistance training program with elastic bands over the course of 12 months (six exercises for whole body training, three sets × 10 repetitions), and a control group (CG, n = 20) that did not perform any training. Blood analysis and body composition were determined at bas…

Profiling of lipid species by normal-phase liquid chromatography, nanoelectrospray ionization, and ion trap–orbitrap mass spectrometry
2013
Detailed analysis of lipid species can be challenging due to their structural diversity and wide concentration range in cells, tissues, and biofluids. To address these analytical challenges, we devised a reproducible, sensitive, and integrated lipidomics workflow based on normal-phase liquid chromatography-Fourier transform mass spectrometry (LC-FTMS) and LC-ITMS(2) (ion trap tandem mass spectrometry) for profiling and structural analysis of lipid species. The workflow uses a normal-phase LC system for efficient separation of apolar and polar lipid species combined with sensitive and specific analysis powered by a chip-based nanoelectrospray ion source and a hybrid ion trap-orbitrap mass sp…
Calorimetric properties of water and triacylglycerols in fern spores relating to storage at cryogenic temperatures.
2007
Abstract Storing spores is a promising method to conserve genetic diversity of ferns ex situ . Inappropriate water contents or damaging effects of triacylglycerol (TAG) crystallization may cause initial damage and deterioration with time in spores placed at −15 °C or liquid nitrogen temperatures. We used differential scanning calorimetry (DSC) to monitor enthalpy and temperature of water and TAG phase transitions within spores of five fern species: Pteris vittata , Thelypteris palustris , Dryopteris filix-mas , Polystichum aculeatum , Polystichum setiferum . The analyses suggested that these fern spores contained between 26% and 39% TAG, and were comprised of mostly oleic ( P. vittata ) or …
Lipid and fatty acid variations inCiona intestinalis ovary after tri-n-butyltin(IV)chloride exposure
2005
Reduction of total lipids (TL) content and significant variations of triglyceride (TG) and phospholipid (PL) fractions were observed as a consequence of exposure of Ciona intestinalis ovaries to tributyltin chloride (TBTCL) solutions. In particular, an evident TG decrease and a PL increase were observed, which probably provoked an increment in membrane fluidity, because of the high concentration of long chain fatty acids and, as a consequence, PL. This could be a cell adaptive standing mechanism towards the pollutants, as observed in Saccharomyces cerevisiae. Also the increase in the content of the polyunsaturated fatty acids (PUFA), important in the synthesis of compounds such as prostagla…
