Benefits of technology

[0015] Phosphatidylserine, also known as PS, is a natural phospholipid with bio-functionality that has made it one of the most promising dietary supplements in the field of brain nutrition. PS and its health benefits have been known to the scientific and nutrition communities since the 1970's. Numerous studies hav

Animals and Diet

[0164] Male Wistar rats originated from the same colonies were obtained from Harlen. Fifty rats were randomly divided into five dietary supplemented groups, in addition to their normal diet: (i) a group fed 0.1 g medium-chain triglycerides (MCT) / 1 ml supplement matrix (MCT group); (ii) a group fed 0.1 g DHA / EPA (20 / 30% of total fatty acids composition, diluted with MCT to generate 30% (w / w) LC-PUFA compound) triglycerides / 1 ml supplement matrix (LC-PUFA group); (iii) a group fed 0.1 g soybean lecithin-derived PS (20% SB-PS w / w) / 1 ml supplement matrix (SB-PS group); and (iv) a group fed 0.1 g PS-{overscore (ω)}3 (20% PS w / w, and total LC-PUFA composition of 30%) / 1 ml supplement matrix (PS group). The supplement matrices were stored at −20° C., and fresh portions were fed to the rats every day. All supplements were handled so as to minimize oxidation of the fatty acids. Rats consumed the diet and water ad libitum. All rats were housed in a standar...

PS-omega-3 in the Treatment of ADHD Children

[0181] Attention-deficit / hyperactivity disorder (ADHD) encompasses a broad constellation of behavioural and learning problems and its definition and diagnosis remain controversial [Kamper (2001) J. Pediatr. 139:173-4; Richardson et al. (2000) Prostaglandins Leukot. Essent. Fatty Acids, 63(1-2):79-87]. The etiology of ADHD is acknowledged to be both complex and multi-factorial. Traditionally, ADHD is the diagnosis used to describe children who are inattentive, impulsive, and / or hyperactive. Roughly 20-25% of children with ADHD show one or more specific learning disabilities in math, reading, or spelling [Barkley, R. A. (1990) Attention-deficit hyperactivity disorder: a handbook for diagnosis and treatment. New York: Guilford Press]. Children with ADHD often have trouble performing academically and paying attention, and may be disorganized, have poor self-discipline, and have low self-esteem. A conservative estimate is that 3-5% o...

Effect of PC-DHA Consumption in ApoE° Mice

Methods

Animal Diet

[0189] Apolipoprotein E deficient (ApoE°) mice [Hayek T. et al. (1994) Biochem. Biophys. Res. Commun. 201:1567-1574] at 8 weeks of age, were assigned randomly (5 mice each) to LC-PUFA enriched lecithin (30% omega-3 of total fatty acids composition; PC-DHA group) or placebo. The mice were fed, besides the regular chow diet, once every three days with either 25 μl PC-DHA or PBS, via oral gavage, during 10 weeks.

[0190] Each mouse consumed approximately 5 mL of water / day, and 5 g of chow / day.

Serum Lipids Peroxidation

[0191] Serum was diluted 1:4 in PBS. Serum susceptibility to oxidation was determined by incubating serum sample with 100 mM of the free radical generating compound, 2′-2′-azobis 2′-amidinopropane hydrochloride (AAPH), which is an aqueous soluble azo compound that thermally decomposes to produce peroxyl radicals at a constant rate. The formation of thiobarbituric reactive substances (TBARS) and of...

Abstract

A lipid preparation including a glycerophospholipid or salt, conjugate and derivatives thereof, particularly phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidyl-inositol (PI), phosphatidylglycerol (PG) and phosphatidic acid (PA), and poly-unsaturated fatty acid (PUFA) acyl groups, particularly long-chain poly-unsaturated fatty acid (LC-PUFA) acyl groups such as omega-3 and/or omega-6 acyl groups, wherein said PUFA is covalently bound to said glycerophospholipid. The preparation possesses an improved bioactivity, and is useful in the treatment of various cognitive and mental conditions and disorders and for maintenance of normal functions of brain-related systems and processes.

Description

RELATED APPLICATION [0001] The present application is a continuation of International Patent Application No. PCT / IL2004 / 000957, filed Oct. 21, 2004, the contents of which are here incorporated by reference in their entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to phospholipids and polar lipids preparations which are enriched with omega-3 and / or omega-6 fatty acids covalently attached to the lipid backbone. The phospholipid preparations of the invention are particularly useful as nutraceuticals, food additives and / or pharmaceutical agents for the treatment of various conditions, in particular related to cognitive functions. [0004] 2. Prior Art [0005] Lipids, and especially polar lipids, nitrogen containing lipids, and carbohydrate containing lipids (phospholipids, sphingosines, glycolipids, ceramides, sphingomyelins) are the major building blocks of cell membranes, tissues, etc. Additionally they play important roles in sig...
