2. Evaluation of the Lipid Quality of Lyophilized Pasteurized Human Milk for Six Months by GC-FID and ESI-MS
Human milk (HM) lipids provide about 50% energy and facilitate the transport and absorption of fat-soluble vitamins for infants, but their composition should be studied when the milk is processed. This study evaluated the lipid quality of lyophilized and vacuum-packed colostrum (C), transitional (T), and mature (M) HM for a period of 1, 30, 60, 90, 120, 150,

4. Simultaneous and accurate determination of water- and fat-soluble vitamins in multivitamin tablets by using an RP-HPLC method
In the present study, a reversed-phase high-performance liquid chromatographic (RP-HPLC) procedure was developed and validated for the simultaneous determination of seven water-soluble vitamins (thiamine, riboflavin, niacin, cyanocobalamin, ascorbic acid, folic acid, and p-aminobenzoic acid) and four fat-soluble vitamins (retinol acetate, cholecalciferol, α

5. Niveis sericos das vitaminas lipossoluveis (A, D e E) em pacientes com atresia biliar e hepatite auto-imune e a relação com o estado nutricional e indicadores clinicos e laboratoriais / Serum levels of fat-soluble vitamins (A, D and E) in patientes with biliary atresia and auto-immune hepatitis and relations with the nutritional status and clinic and laboratorial indicators
The chronic liver diseases can cause malabsorption of lipids and fat-soluble vitamins, leading to a deficient nutritional status. The aim of research was: to evaluate the relation between serum levels of fat-soluble vitamins (A, D and E) on chidren and adolescents with biliary atresia (BA) and auto-immune hepatitis (AIH) with the nutritional status and with

6. Composição nutricional e determinação simultanea de vitaminas lipossoluveis em rações para frangos de corte. / Nutritional composition and sumiltaneous fat soluble vitamin determination in rations for cut chicken.
A avicultura está inserida em um mercado altamente competitivo, onde a alimentação equilibrada das aves é necessária para a máxima expressão do potencial genético e, conseqüentemente, para uma maior produtividade. Nesse contexto, a importância das vitaminas lipossolúveis, além de outros nutrientes, deve ser considerada, já que têm influência d

7. ESTUDO DA INTERAÇÃO ENTRE AS VITAMINAS LIPOSSOLÚVEIS COM CÁDMIO E CHUMBO POR ASV EM MEIO ORGÂNICO / STUDY OF INTERACTION AMONG FAT-SOLUBLE WITH CADMIUM AND LEAD BY ASV IN ORGANIC MEDIA
No presente trabalho dois métodos voltamétricos foram investigados para o estudo da interação entre os metais, Cd e Pb, e vitaminas lipossolúveis (palmitato de retinol VA; colecalciferol VD; acetato de α-tocoferol VE; filoquinona - VK). Devido à característica hidrofóbica destas vitaminas, a voltametria foi conduzida em meio orgânico. No primei

8. Oil and fat in broiler nutrition
The terms "fat" and "oil" refer to triglycerides of several profiles of fatty acids. Fatty acids that are not bound to other organic components as glycerol are the so-called free fatty acids. Lipids constitute the main energetic source for animals and they have the highest caloric value among all the nutrients. Linoleic acid is the only fatty acid whose diet

9. Vitaminas lipossolúveis em alimentos: uma abordagem analítica
This study concerns certain problems inherent to the determination of fat-soluble vitamins in food, from extraction methods to identification and quantification. The discussion involves the main official and unofficial extraction methods coupled with spectrophotometric and HPLC techniques in which vitamins samples are obtained through liquid-liquid-solid and

11. Virucidal activity of retinal.
Herpes simplex virus type 2 and simian virus 40 were rapidly inactivated by retinal at micromolar concentrations. Other fat-soluble vitamins, particularly vitamin A derivatives, were also active against herpes simplex virus type 2 and several lipid-containing bacteriophages.

12. A genetic model for absent chylomicron formation: mice producing apolipoprotein B in the liver, but not in the intestine.
The formation of chylomicrons by the intestine is important for the absorption of dietary fats and fat-soluble vitamins (e.g., retinol, alpha-tocopherol). Apo B plays an essential structural role in the formation of chylomicrons in the intestine as well as the VLDL in the liver. We have developed genetically modified mice that express apo B in the liver but
