Biochemical Characterization of Coriander Cakes Obtained by Extrusion

This study was designed to examine the effect of operating conditions such as nozzle diameter on fatty acid, sterol, and tocol composition of coriander cakes. Eight fatty acids were identified, with petroselinic acid accounting for 75-77% of the total fatty acids, followed by linoleic, oleic, and palmitic acids, accounting for 12-13%, 5% and 3%, respectively, of the total fatty acids. beta-Sitosterol was the major sterol in all oils with 33-35% of total sterols. The next major sterols in all oils were stigmasterol (24% of total sterols) and Delta(7)-stigmasterol (15% of total sterols). Coriander cake contained higher amounts of total tocotrienol where gamma-tocotrienol was the main compund

Lower paraoxonase 1 activity in Tunisian bipolar I patients

Abstract Background The purpose of this study was to investigate the variations of paraoxonase activity and lipid profile in bipolar I patients, and the association of this activity with the sociodemographic, clinical and therapeutic characteristics of this population. Patients and methods Our study included 66 patients with bipolar I disorder and 64 controls aged 37.9 ± 12.6 and 36.3 ± 18.2 years, respectively. Paraoxonase activity was determined by kinetic methods; high-density lipoprotein cholesterol (c-HDL), low-density lipoprotein cholesterol (c-LDL), triglycerides and total cholesterol were determined by enzymatic methods; apolipoprotein (Apo)A1, ApoB and lipoprotein (a) (Lp(a)) were determined by immunoturbidimetry using Konelab 30 equipment (Thermo Scientific). Results Compared with controls, patients had a significantly lower paraoxonase activity and ApoA1 level, and significantly higher total cholesterol, c-LDL and Lp(a) level and ApoB/ApoA1 ratio. Furthermore, paraoxonase activity was significantly correlated with c-HDL values (r = 0.5612; P Conclusions Bipolar patients had a significant decrease in paraoxonase activity and perturbations in their lipid profile that contribute to increased risk of cardiovascular diseases. Decrease in this activity was significantly associated with treatment with lithium but not with sociodemographic and clinical characteristics. Therefore, such patients require specific care, particularly with regard to their lipid profile.</p
