A method for determination of Cu, K, Mg, Mn, P, and Zn in instant soups by MIP OES with N2 plasma was developed. Sample preparation procedure consisted of microwave-assisted digestion with dilute nitric acid solution. Accuracy was evaluated based on the analysis of three certified reference materials: NIST 1515 (apple leaves), NIST 1568b (rice flour) and NIST 3234 (soy flour). Recoveries ranged from 83.3 to 107.5 % for target elements in these materials. Addition and recovery experiments were performed and recoveries ranged from 86.0 to 106.0 %. All determinations were performed using external calibration. Limits of detection for Cu, K, Mg, Mn, P, and Zn were 0.09, 4.90, 1.00, 0.04, 5.40 and 0.88 mg kg-1, respectively. Concentrations ranges of Cu, K, Mg, Mn, P and Zn in various types of instant soups samples were found between 1.31 - 13.8, 1,135 - 17,824, 172 - 567, 1.72 - 12.1, 608 - 1,826 and 2.90 - 12.1 mg kg-1, respectively. The use of N2 microwave-induced plasma is demonstrated as a low cost alternative for routine analys...
Authors: Karimi G, Vard B, Riyahi R, Motlagh ME, Heshmat R, Kelishadi R Abstract This cross-sectional study was conducted among 14,400 Iranian students, aged 7-18 years to determine the association between the frequency of family dinner and mental health. Family dinner frequency, family relationship, life satisfaction (LS), self-perceived health and anxiety were assessed by validated questionnaires. Of 14,274 participants, 50.6% were boys and 71.4% were urban residents, with a mean (SD) age of 12.28 (3.16) years. Family dinner frequency was significantly correlated with LS (boys: β = 0.27, p
In this study we explored the use of a natural compound rubusoside (RUB) as a solubilizer to enhance the solubility of a fluorescence-labeled C6-Ceramide (NBD C6-Ceramide) and to characterize its pharmacokinetics and tissue distribution in an animal model. RUB significantly enhanced the solubility of NBD C6-Ceramide by forming nanomicelles, and efficiently delivered NBD C6-Ceramide in rats by oral and intravenous administration. RUB loaded 1.96% of NBD C6-Ceramide in the nanomicelles and solubilized it to a concentration of 3.6 mg/mL in water. NBD C6-Ceramide in nanomicelles remained stable in aqueous solutions, all...

ConteAbstractInflammation ensuing from vascular injury promotes intimal hyperplasia (IH) and restenosis. Resolvin D1 (RvD1) is a lipid mediator that attenuates IH in vivo when delivered locally to the vessel wall in animal models. We tested the hypothesis that peri-procedural oral administration of RvD1 could blunt the local inflammatory response to angioplasty, and attenuate downstream IH. Carotid angioplasty was per...
