Effect of Curcumin, Mixture of Curcumin and Piperine and Curcum (Turmeric) on Lipid Profile of Normal and Hyperlipidemic Rats
The Egyptian Journal of Hospital Medicine Vol., 21: 145 – 161 December 2005 I.S.S.N: 12084 2002–1687 Effect of Curcumin, Mixture of Curcumin and Piperine and Curcum (Turmeric) on Lipid Profile of Normal and Hyperlipidemic Rats GHADA, Z. A. Soliman Lecturer of Biochemistry, Biochemistry Department, National Nutrition Institute, Cairo Abstract Curcumin is a polyphenolic, yellow pigment obtained from rhizomes of Curcuma longa (curcum), used as a spice and food colouring. The extracts have several pharmacological effects. We evaluated the effect of curcum, curcumin, and mixture of curcumin and piperine on plasma lipids in normal and hypercholesterolemic rats. A total of 270 rats, divided into 27 groups, were used. G1, G11: control, G2-G11: normal rats fed control diet supplemented with different levels of curcumin and curcum (G2-G6: 0.1%, 0.25%, 0.5%, 1.0%, 2.0% respectively, G7-G11: 1.67%, 4.167%, 8.34%, 16.67%, and 33.34). G12-G26: at first fed control diet supplemented with 2% cholesterol then G13-17, 21-25 fed a control diet supplemented with different levels of curcumin, and curcum [the same levels as G2-G11; G18-20 fed control diet supplemented with mixture of curcumin (0.1, 0.25, 0.5%) and piperine (20 mg/kg BW)], G12 was sacrificed before addition of studied materials, G26 were fed control diet. Lipid profile, triacylglycerol and phospholipids of plasma and organs as liver and heart were measured. Serum cholesterol (total, LDL-C, VLDL-C), triacylglycerol and phospholipids contents were elevated in cholesterol-fed rats, while HDL-C were decreased. -

Phospholipid Metabolism in Stimulated Human Platelets: CHANGES in PHOSPHATIDYLINOSITOL, PHOSPHATIDIC ACID, and LYSOPHOSPHOLIPIDS
Phospholipid Metabolism in Stimulated Human Platelets: CHANGES IN PHOSPHATIDYLINOSITOL, PHOSPHATIDIC ACID, AND LYSOPHOSPHOLIPIDS M. Johan Broekman, … , Jean W. Ward, Aaron J. Marcus J Clin Invest. 1980;66(2):275-283. https://doi.org/10.1172/JCI109854. Endogenous phospholipid metabolism in stimulated human platelets was studied by phosphorus assay of major and minor components following separation by two-dimensional thin-layer chromatography. This procedure obviated the use of radioactive labels. Extensive changes were found in quantities of phosphatidylinositol (PI) and phosphatidic acid (PA) as a consequence of thrombin or collagen stimulation. Thrombin addition was followed by rapid alterations in the amount of endogenous PI and PA. The decrease in PI was not precisely reciprocated by an increase in PA when thrombin was the stimulus. This apparent discrepancy could be explained by removal of a transient intermediate in PI metabolism, such as diglyceride, formed by PI-specific phospholipase C (Rittenhouse-Simmons, S., J. Clin. Invest.63: 580-587, 1979). Diglyceride would be unavailable for PA formation by diglyceride kinase, if hydrolyzed by diglyceride lipase (Bell, R. L., D. A. Kennerly, N. Stanford, and P. W. Majerus. Proc. Natl. Acad. Sci. U. S. A.76: 3238-3241, 1979) to yield arachidonate for prostaglandin endoperoxide formation. Thrombin-treated platelets also accumulated lysophospho-glycerides. Specifically, lysophosphatidyl ethanolamines accumulated within 15s following thrombin addition. Fatty acid and aldehyde analysis indicated phospholipase A2 activity, with an apparent preference for diacyl ethanolamine phosphoglycerides. In the case of collagen, these changes occurred concomitantly with aggregation and consumption of oxygen for prostaglandin endoperoxide formation. These studies of endogenous phospholipid metabolism provide information supporting the existence of […] Find the latest version: https://jci.me/109854/pdf Phospholipid Metabolism in Stimulated Human Platelets CHANGES IN PHOSPHATIDYLINOSITOL, PHOSPHATIDIC ACID, AND LYSOPHOSPHOLIPIDS NI. -

Dickschat* - [email protected] Published: 20 December 2011 * Corresponding author This article is part of the Thematic Series "Biosynthesis and function of secondary metabolites". Keywords: actinomycetes; FAMEs; fatty acid biosynthesis; GC–MS; volatiles Associate Editor: S. Flitsch © 2011 Dickschat et al; licensee Beilstein-Institut. License and terms: see end of document. Abstract The volatiles released by Micromonospora aurantiaca were collected by means of a closed-loop stripping apparatus (CLSA) and analysed by GC–MS. The headspace extracts contained more than 90 compounds from different classes. Fatty acid methyl esters (FAMEs) comprised the major compound class including saturated unbranched, monomethyl and dimethyl branched FAMEs in diverse structural variants: Unbranched, α-branched, γ-branched, (ω−1)-branched, (ω−2)-branched, α- and (ω−1)-branched, γ- and (ω−1)-branched, γ- and (ω−2)-branched, and γ- and (ω−3)-branched FAMEs. FAMEs of the last three types have not been described from natural sources before. The structures for all FAMEs have been suggested based on their mass spectra and on a retention index increment system and verified by the synthesis of key reference compounds. In addition, the structures of two FAMEs, methyl 4,8-dimethyldodecanoate and the ethyl-branched compound methyl 8-ethyl-4-methyldodecanoate were deduced 2 2 2 2 from their mass spectra. -

In this study, the behavior of the caprylic and capric acids formulations containing octyl salicylate were investigated. The formulations were prepared using homogenization proses. The characteristics of the formulation such as particle size, flow behavior, microscopic view and absorbance of the formulations were investigated. Particle sizes of the formulations were found ranging from 352.7 - 704.2 nm. The viscosity of the formulations changed as the shear rate was varied and could be classified as non-Newtonian fluids. The viscosity decreases when the fluid undergoes longer shear stress with time. The formulations containing octyl salicylate shows higher absorbance as compared to the formulations without octyl salicylate. -

Monoacylglycerol As a Metabolic Coupling Factor in Glucose-Stimulated Insulin Secretion
Université de Montréal Monoacylglycerol as a metabolic coupling factor in glucose-stimulated insulin secretion par Shangang Zhao Département de Biochimie Faculté de Médecine Mémoire présentée à la Faculté des Etudes Supérieures en vue de l’obtention du grade de maître ès sciences en Biochimie Décembre 2010 © Shangang Zhao, 2010 Université de Montréal Faculté des études supérieures Ce mémoire intitulée : Monoacylglycerol as a metabolic coupling factor in glucose-stimulated insulin secretion Présenté par : Shangang Zhao a été évaluée par un jury composé des personnes suivantes: Dr Tony Antakly, président-rapporteur Dr Marc Prentki, directeur de recherche Dr Ashok K. Srivastava, membre du jury i Résumé Les cellules beta pancréatiques sécrètent l’insuline lors d’une augmentation post-prandiale du glucose dans le sang. Ce processus essentiel est contrôlé par des facteurs physiologiques, nutritionnels et pathologiques. D’autres sources d’énergie, comme les acides aminés (leucine et glutamine) ou les acides gras potentialisent la sécrétion d’insuline. Une sécrétion d’insuline insuffisante au besoin du corps déclanche le diabète. Le rôle que joue l’augmentation du calcium intracellulaire et les canaux K+/ATP dans la sécrétion d’insuline est bien connu. Bien que le mécanisme exact de la potentialisation de la sécrétion d’insuline par les lipides est inconnu, le cycle Glycérolipides/Acides gras (GL/FFA) et son segment lipolytique ont été reconnu comme un composant essentiel de la potentialisation lipidique de la sécrétion d’insuline. Le diacylglycérol, provenant de la lipolyse, a été proposé comme un signal lipidique important d’amplification. Cependant, l’hydrolyse des triglycérides et des diacylglycérides a été démontrée essentielle pour la sécrétion d’insuline stimulée par le glucose, en suggérant un rôle du monoacylglycérol (MAG) dans ce processus.
