13. Arachidonic acid affects biofilm formation and PGE2 level in Candida albicans and non-albicans species in presence of subinhibitory concentration of fluconazole and terbinafine
Candida albicans utilizes arachidonic acid (AA) released during the course of infection (Candidiasis) from phospholipids of infected host cell membranes and synthesizes extracellular prostaglandin(s) which play an important role in hyphae formation and host cell damage. C. albicans biofilms secrete significantly more prostaglandin(s) and evidence suggests t

14. Espectroscopia de fósforo por ressonância magnética em malformações do desenvolvimento cortical
IntroductionMalformations of cortical development (MCD) result from disruptions in the dynamic process of cerebral corticogenesis and are important causes of epilepsy, motor deficits and cognitive impairment.ObjectivesThe aim of this study was to evaluate phospholipids metabolism in vivo in a series of patients with epilepsy and MCD.MethodsThirty-seven patie

15. Perimicrovillar membrane assembly: the fate of phospholipids synthesised by the midgut of Rhodnius prolixus
In this study, we describe the fate of fatty acids that are incorporated from the lumen by the posterior midgut epithelium of Rhodnius prolixus and the biosynthesis of lipids. We also demonstrate that neutral lipids (NL) are transferred to the haemolymphatic lipophorin (Lp) and that phospholipids remain in the tissue in which they are organised into perimicr

16. The termal influence on the dynamics of cell membranes: a contribution to the conservation of Steindachneridion parahybae (Siluriformes: Pimelodidae), a threatened species of fish / A influência térmica na dinâmica das membranas celulares: uma contribuição na conservação de Steindachneridion parahybae (Siluriformes: Pimelodidae), uma espécie de peixe ameaçada de extinção
Temperature is the most important environmental factor affecting the activity of ectothermic animals such as fish. Compensatory adjustments to temperature occur with time courses ranging from less than a minute to more than a month, and membranes are the first targets affected by change of temperature, and their lipid components respond immediately to this c

17. Caracterização de lecitinas comerciais por espectrometria de massas ambiente com ionização sonic-spray / Characterization of commercial lecithins by easy ambient sonic-spray ionization mass spectrometry
Os fosfolipídios são definidos como o grupo de moléculas que contém um grupamento fosfato. Por apresentarem características anfipáticas, este grupo de moléculas se organiza naturalmente em bicamadas, originando as membranas dos seres vivos. Industrialmente são capazes de estabelecer interfaces óleo/água, possibilitando a formação e estabilizaçã

18. Propriedades reológicas e interfaciais de sistemas modelo constituídos de água, proteínas lácteas e fosfolipídeos em diferentes proporções / Rheological and interfacial properties of model systems consisting of water, milk proteins and phospholipids in different proportions
As proteínas do leite são largamente utilizadas nas indústrias alimentícias. Elas podem ser classificadas em relação a suas estruturas: proteínas flexíveis, para as caseínas e as proteínas globulares, para as proteínas solúveis. A superfície do pó reflete a interface ar/água das gotículas de secagem e sabe-se pouco a respeito das interações

19. Lepromatous leprosy patients produce antibodies that recognise non-bilayer lipid arrangements containing mycolic acids
Non-bilayer phospholipid arrangements are three-dimensional structures that form when anionic phospholipids with an intermediate structure of the tubular hexagonal phase II are present in a bilayer of lipids. Antibodies that recognise these arrangements have been described in patients with antiphospholipid syndrome and/or systemic lupus erythematosus and in

20. Characterization of lyophilized liposomes produced with non-purified soy lecithin: a case study of casein hydrolysate microencapsulation
A commercial casein hydrolysate was microencapsulated in liposomes produced with non-purified soy lecithin, cryoprotected with two different disaccharides and lyophilized. The encapsulation efficiency of casein hydrolysate ranged from 30 to 40%. The powders were analyzed by differential scanning calorimetry (DSC), scanning electron micrography (SEM), infrare

21. Plasma kinetics of an LDL-like nanoemulsion and lipid transfer to HDL in subjects with glucose intolerance
OBJECTIVE: Glucose intolerance is frequently associated with an altered plasma lipid profile and increased cardiovascular disease risk. Nonetheless, lipid metabolism is scarcely studied in normolipidemic glucose-intolerant patients. The aim of this study was to investigate whether important lipid metabolic parameters, such as the kinetics of LDL free and est

22. Estudo do papel biológico da enzima ácido graxo sintase (FASN) em células endoteliais derivadas dos vasos sanguíneos / Study of the biological role of the enzyme fatty acid synthase (FASN) in endothelial cells derived from blood vessels
Fatty acid synthase (FASN) is the anabolic enzyme with high expression and activity in several human malignancies, which is responsible for the endogenous synthesis of saturated fatty acids and consequently of the phospholipids present in cell membranes. Inhibition of FASN with orlistat (Xenical), an anti-obesity drug, is described as having anti-neoplastic

INTRODUÇÃO: As malformações do desenvolvimento cortical (MDC) resultam de distúrbios no dinâmico processo de corticogênese cerebral e são importante causa de epilepsia grave, atraso do desenvolvimento, déficits motores e cognitivos. O papel do metabolismo na epilepsia humana tem sido extensamente debatido, e há inúmeras evidências que apontam par
