1. Effects of carob ( Ceratonia siliqua ) pod byproduct on quail performance, egg characteristics, fatty acids, and cholesterol levels
ABSTRACT This study was carried out to determine the effects of a carob (Ceratonia siliqua) byproduct (CB) supplement in diets for laying Japanese quail (Coturnix coturnix japonica) on performance and egg internal-external quality traits, fatty acid profile, and cholesterol content. A total of 225 female quail at 12 weeks of age were distributed into five tr

2. Estudo das mudanças quali e quantitativas da participação de ácidos graxos no sebo de pacientes com acne inflamatória, graus II ou III, em uso sistêmico de limeciclina e/ou suplementação oral à base de ácidos linoleico, gamalinolênico / Study of qualitative and quantitative changes of fatty acids in the sebum of patients with inflammatory acne, grade II or III, under systemic use of lymecycline and/or oral supplementation based on linoleic, gamma-linolenic, and oleic acids using gas chromatography
Introdução: Acne é uma dermatose que apresenta o padrão do sebo alterado, tanto quali, quanto quantitativamente. Objetivos: Estudar as possíveis alterações quali e quantitativas dos ácidos graxos encontrados no sebo de portadores de acne vulgar graus II ou III mediante ao uso diário de limeciclina e/ou suplemento oral a base de ácidos linoleico, ga

3. Aeration effect on Spirulina platensis growth and γ-linolenic acid production
The influence of aeration on algal growth and gamma-linolenic acid (GLA) production in a bubble column photobioreactor was investigated. Studies were performed in a 20-L reactor at different aeration rates (0.2-2.5 vvm). Static, continuous, and periodic operation of air resulted in 41.9%, 88.4%, and 108% air saturation of dissolved oxygen, for which the corr

4. Análise do papel da prostaglandina E2 na proliferação, migração e apoptose na linhagem de glioma humano T98G e o efeito do ácido gama-linolênico e ibuprofeno sobre este prostanóide. / Analysis of the role of prostaglandin E2 on proliferation, migration and apoptosis in the T98G human glioma cell line and the effects of gamma - linolenic acid and Ibuprofen on this prostanoid.
Gliomas são tumores do sistema nervoso central e o glioblastoma multiforme (GBM) é sua forma mais comum e de pior prognóstico. A proliferação desordenada, migração estão entre os processos biológicos que conferem ao GBM um comportamento altamente agressivo. O objetivo deste estudo foi analisar in vitro o papel de PGE2 na proliferação, migração e

5. Screening of microbial lipases and evalutaion of their potential to produce glycerides with high gamma linolenic acid concentration
Gamma-linolenic acid (GLA, 18:3, cis- 6,9,12-octadecatrienoic acid), an important compound in n-6 eicosanoid family biosynthesis, occurs in the lipids of a few plant and microbial sources. This study focused on the screening of microbial strains with suitable lipase activity for enrichment of GLA by selective hydrolysis of the borage oil (21.6 % of GLA/total

6. Aplicação de lipases microbianas na obtenção de concentrados de ácidos graxos poliinsaturados
Several polyunsaturated fatty acids (PUFA) belonging to the ômega 6 series, such as cis-6,9,12 gamma-linolenic acid, as well as those of the ômega 3 series, such as cis-5,8,11,14,17-eicosapentaenoic acid and cis-4,7,10,13,16,19-docosahexaenoic acid are of considerable interest due to their nutritional and therapeutic properties. Methods used for the concen

7. Cholesterol changes the fatty acid composition of rat enterocytes
The effect of free cholesterol on the fatty acid composition and growth of rat fetal enterocytes was investigated in the absence and presence of 10% (v/v) fetal calf serum. Cholesterol caused a significant reduction of cell number after 6 and 12 h in culture. The fatty acid composition of enterocytes cultured in the presence of serum was also changed by the

8. Estudo da utilização de lipases no enriquecimento de oleos de sardinha e Mucor sp em acidos graxos poliinsaturados
The present work reports the study of the hydrolysis and etherification reactions catalyzed by microorganism lipases, which were isolated at the "Laboratorio de Bioquímica de Alimentos - FEA - UNICAMP", belonging to Rhizopus sp, Geotrichum sp, Aspergillus sp and the commerciallipase Candida cylindracea. The aim was the enrichment of polyunsaturated fatty ac

9. Evening primrose oil in rheumatoid arthritis: changes in serum lipids and fatty acids.
The serum concentration of lipids and composition of fatty acids after overnight fasting were studied in 18 patients with rheumatoid arthritis treated for 12 weeks with either 20 ml of evening primrose oil containing 9% of gamma-linolenic acid or olive oil. The serum concentrations of oleic acid, eicosapentaenoic acid, and apolipoprotein B decreased and thos

11. Arachidonic acid deficiency in streptozotocin-induced diabetes.
Fatty acid compositions of phospholipids of heart, liver, kidney, aorta, and serum from rats having streptozotocin-induced diabetes were determined and compared with those of nondiabetic controls. Linoleic and dihomo-gamma-linolenic acids were increased whereas arachidonic acid was decreased in most tissues, suggesting an impairment of delta 5-desaturase act

12. Hydrogenation of Unsaturated Fatty Acids by Treponema (Borrelia) Strain B25, a Rumen Spirochete1
The time course of hydrogenation of linoleic acid to trans-11-octadecenoic acid was observed in a growing culture of Treponema (Borrelia) strain B25. A conjugated fatty acid, cis-9, trans-11-octadecadienoic acid, was identified as an intermediate in the process. The isomerase responsible for the conversion of linoleic acid to the conjugated fatty acid was fo
