Background: Nutritional choices, which include the source of dietary fatty acids (FA), have an important significant impact on coronary artery disease (CAD). We aimed to determine on patients with CAD the relationships between Trans fatty acids (Trans FA) and different CAD associated parameters such as inflammatory and oxidative stress parameters in addition to Gensini score as a vascular severity index.

Methods: Fatty acid profiles were established by gas chromatography from 111 CAD patients compared to 120 age-matched control group.

Background: Some factors related to diet are known to be involved in the progression of atherosclerosis in humans.

Methods: The relationship between plasma fatty acid (FA) levels and the severity of coronary artery disease (CAD), evaluated by Gensini score (GS), was investigated in CAD Tunisian patients compared to controls. Lipid profiles were analyzed, GS was calculated in CAD and non-CAD patients and compared to controls.

Long and very long chain fatty acids (LCFAs and VLCFAs) may play an active role in coronary artery diseases (CAD) etiology. Our aim was to evaluate the associations between LCPUFAs (C20:4n-6; C20:5n-3 and C22:6n-3) and VLCSFAs (C22:0, C24:0; and C26:0), as well as markers of peroxisomal integrity evaluated by phytanic acid and plasmalogen-C16:0 (PL-C16:0) in addition to the markers of lipid peroxidation (malondialdehyde [MDA] and conjugated dienes [CD]) and inflammation (high sensitivity C-reactive protein [hs-CRP]) with vascular severity evaluated by Gensini score in order to determine their possible effects on CAD in Tunisian population. Lipidomic strategy based on GC/MS-SIM was used to quantify LCPUFAs, VLCSFAs, and PL-C16:0 in red blood cells of CAD patients, non-CAD patients, and controls.

Background: Several lipid metabolism alterations have been described in the brain and plasma of Alzheimer's disease (AD) patients, suggesting a relation between lipid metabolism alteration and dementia.

Objective: We attempted to identify blood fatty acids as biomarkers of dementia.

Methods: Fatty acid profiles were established using gas chromatography with or without mass spectrometry on matched plasma and red blood cells (RBCs) of demented patients diagnosed with AD, vascular dementia, or other dementia, and compared with a control group of elderly individuals.
