1. NMR in Analysis of the Nutritional Value of Lipids from Muscles and Livers of Wild Amazonian Fishes with Different Eating Habits Over Seasonal Variation
Endogenous and environmental factors can influence the lipid contents of fishes among which, in the Amazon River, seasonal dynamics influences stand out. Herein, nine most consumed Amazonian fish species had their lipid composition evaluated in terms of effects of tissue, season and eating habits. Higher amounts of lipids were obtained from fish livers than

2. Fraud with the addition of cow's milk alters the lipid fraction of buffalo mozzarella
Abstract The shortage of milk at certain times of the year leads to adulteration of buffalo mozzarella, and these frauds alter the composition of milk and buffalo derivatives. This study describes the dynamics of the adulteration on the nutritional quality of mozzarella. Mozzarella was produced from buffalo milk incorporated with cow milk at 0, 10, 20, 30, 4

3. Drying of microalga Scenedesmus obliquus BR003 in a gas dryer at low temperatures
ABSTRACT: Development of efficient and specific equipment to dry microalgae is essential for commercial use of these microorganisms that show high growth rates and biotechnological potential. Drying costs of microalgae biomass are still high and they should be reduced for the production of compounds with low added value. Therefore, we evaluated the drying p

4. Study on the Application of Electric Field to Giant Vesicles Comprised of 1,2-Dilauroyl-Sn-Glycero-3-Phosphatidylcholine Using Optical Fluorescence Microscopy
The influence of alternating electric field (AC) in the structure and dynamics of giant unilamellar vesicles (GUVs) comprised of 1,2-dilauroyl-sn-glycero-3-phosphatidylcholine (DLPC) is reported. The investigations were conducted by using optical fluorescence microscopy as the method of analysis. The lipid membrane of the DLPC GUVs at the fluid phase can be

5. Degradability and kinetics of fibrous particles in cattle fed diets based on corn silage and concentrates with or without addition of lipids
ABSTRACT Eight rumen-cannulated steers were assigned to two 4 × 4 balanced Latin squares to evaluate degradability and kinetics of fiber particles from diets based on corn silage and supplements with or without addition of lipids. Dietary treatments were: only corn silage (T1), corn silage plus concentrate with no added lipids (T2), corn silage plus concent

6. Heterosis and genetic parameters for grain quality in oat segregating populations
ABSTRACT Improvement of quality-related traits of grains is a constant concern in white oat breeding programs, which challenges breeders to understand their dynamics. The performance of different genetic combinations must be thoroughly evaluated to make high nutritional quality cultivars available. This study aimed to estimate the heterosis on F1 and F2 gene

7. 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

8. Electron paramagnetic resonance study of lipid and protein membrane components of erythrocytes oxidized with hydrogen peroxide
Electron paramagnetic resonance (EPR) spectroscopy of spin labels was used to monitor membrane dynamic changes in erythrocytes subjected to oxidative stress with hydrogen peroxide (H2O2). The lipid spin label, 5-doxyl stearic acid, responded to dramatic reductions in membrane fluidity, which was correlated with increases in the protein content of the membran

9. Estrutura e dinâmica de DNA confinado entre membranas lipídicas não-catiônicas. / Structure and dynamics of DNA confined in-between non-cationic lipid membranes.
Um estudo experimental sobre os aspectos estruturais e dinâmicos de um complexo hidratado de fragmentos de DNA (150 pb) e fases lamelares de lipídios zwitteriônicos é apresentado. Variando-se a hidratação, é possível controlar o confinamento imposto por essa matriz hospedeira sobre os nucleotídeos inseridos na camada aquosa. O arranjo supramolecular

10. Dinâmica molecular e particionamento do marcador de spin di-terc-butil nitróxido em membranas de estrato córneo. Efeito de Terpenos / Molecular dynamics and partitioning Bookmark spin di-tert-butyl nitroxide in membrane of stratum corneum. Effect of Terpenes
Os terpenos são uma classe muito promissora de facilitadores de permeação da pele devido aos seus baixos potenciais de irritação na pele. Neste trabalho utilizamos a espectroscopia de ressonância paramagnética eletrônica (RPE) do pequeno marcador de spin di-terc-butil nitróxido (DTBN) que particiona na fase aquosa e hidrocarbônica, para estudar a i

11. Molecular dynamics of articaine in POPC membranes / Dinamica molecular de articaina em membranas POPC
We studied the interactions of articaine - a local anesthetic widely used for me- dical and odontological applications - with model membranes of POPC (palmitoyl-oleyl-phosphatidylcholine) at biological relevant conditions. We have employed molecular dynamics technique, which allowed us to investigate the system at molecular level. Firstly, we applied quantum

12. Mithocondrial dysfunction and gene expression are mechanism envolved in the prograssion of hypertrophy to heart failure in mice CIRSKOand PGC-1βKO / Disfunção mitocondrial e expressão gênica alterada como mecanismos envolvidos na progressão da hipertrofia para insuficiência cardíaca em camundongos CIRSKO e PGC-1βKO
Heart failure (HF) is the end stage of different types of cardiovascular diseases and it is characterized by changes in the metabolic and myocardial contractility. We use the models cre-lox with specific knockout for insulin receptor substrate (IRS) and co-activator of PPAR (PGC-1b) (basal and pressure overload). The objective was understood the role in the
