The results revealed that olive fruits of OMW-RP amended plants had higher contents of polyphenols and mannitol indicating that agronomic application of OMW with RP generated an oxidative stress. Land spreading of OMW with RP altered the relative proportions of individual sugars in leaves and fruits.

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.

Methods: In vitro and in vivo cholinesterase activity, brain oxidative status, body and brain weight and plasma lipid profile were measured in control rats, HFD-fed rats and HFD-fed rats treated by PSO, PL, PJ and PP.
Results: In vitro study showed that PSO, PL, PP, PJ inhibited cholinesterase activity in dose dependant manner.
Tunisia has the highest prevalence of hemodialysis patients compared to the other countries in North Africa. Dialysis centers rarely offer an exercise program to prevent physiological and psychological dialysis therapy-related alterations in chronic hemodialysis patients. To examine the effect of combined endurance-resistance training program on physiological and psychological outcomes in patients undergoing hemodialysis.

In the present study, flowers, leaves, juice and peel of two pomegranate varieties, ornamental variety "Nana" (NV) and sweet variety "Tounsi" (TV) were compared for their phenolic contents and antioxidant activity. Seeds oils were compared also for their fatty acids (FA) composition.

Methods: Aggrecan release from human OA cartilage explants and human stem cell-derived cartilage discs was evaluated, and cartilage-conditioned media were used for Western blotting. Gene expression was analyzed by real-time polymerase chain reaction.
Increased levels of 7-ketocholesterol (7KC), which results mainly from cholesterol auto-oxidation, are often found in the plasma and/or cerebrospinal fluid of patients with neurodegenerative diseases and might contribute to activation of microglial cells involved in neurodegeneration. As major cellular dysfunctions are induced by 7KC, it is important to identify molecules able to impair its side effects. Since consumption of olive and argan oils, and fish is important in the Mediterranean diet, the aim of the study was to determine the ability of oleic acid (OA), a major compound of olive and argan oil, and docosahexaenoic acid (DHA) present in fatty fishes, such as sardines, to attenuate 7KC-induced cytotoxic effects.
