13. Café (Coffea arabica, L.) submetido a diferentes condições de torrefação: caracterização química e avaliação da atividade antioxidante e sensorial / Coffee (Coffea arabica, L.) submitted to different roasting conditions: chemical characterization and evaluation of sensorial and antioxidant activity
Evaluation of antioxidant activity of plant phenolic compounds has been studied as an alternative to the use of synthetic antioxidants, such as butil-hydroxy -toluene (BHT). In this paper we evaluated the in vitro antioxidant capacity of coffee extracts (ether, ethanol and aqueous) and fractions ( free, bound and unbound) roasted for different periods of tim

14. Efeitos do destreinamento e da dieta hiperlipidica nos mecanismo moleculares de indução de obesidade e resitencia a insulina / Effects of detraining and high-fat diet on molecular mechanisms of obesity and insulin resistance
The cessation of physical training (detraining) results in rapid fat mass accretion, gain weight and insulin resistance in both humans and animals. However, little is know about the cellular basis for the effect. The aim of this study was to investigate the PI3-kinase/Akt and CAP/Cbl signaling pathways both involved with insulin-stimulated glucose uptake in

15. Efeitos do inseticida organofosforado metil paration (Folisuper 600 BR) sobre biomarcadores do estresse oxidante no teleósteo de água doce matrinxã Brycon cephalus (GUNTER, 1869)
Methyl parathion (MP) is an organophosphorus insecticide worldwide used in agriculture and aquaculture due to its high activity against a broad spectrum of insect pests. It is employed as pesticide in agriculture and in food storage shelters, as well as in fish culture tanks to kill aquatic larval stages of insects. The effect of exposure to 2 ppm of a comme

16. Efeitos fisiológicos e bioquímicos causados pela deposição de ferro particulado em Clusia hilariana, uma espécie de restinga / Physiological and biochemical effects of iron ore dust in Clusia hilariana, a plant of restinga
Clusia hilariana, a CAM plant with crucial ecological role, has a broad distribution in brazilian restingas. With the aim to evaluate the physiological and biochemical effects of iron ore particulate matter (MSPFe), deposited in different fashions, on this species, three distinct experiments were carried out. Young plants were hydroponic cultivated in Hoagla

17. Influência de um novo produto fermentado de soja sobre o metabolismo lipídico tecidual em ratos submetidos a uma dieta enriquecida com colesterol.
In relation to many types of diets, soybean has been researched as a possible cohelping resource in the treatment of diverse pathologies. Therefore, the objective of this current work was to investigate the manifestation of a new soybean fermented product with added Enteroccocus Faecium and Lactobaccilus Jugurti on the lipid metabolism of male Wistar rats, a

18. Heterogeneous response of adipose tissue to cancer cachexia
Cancer cachexia causes disruption of lipid metabolism. Since it has been well established that the various adipose tissue depots demonstrate different responses to stimuli, we assessed the effect of cachexia on some biochemical and morphological parameters of adipocytes obtained from the mesenteric (MES), retroperitoneal (RPAT), and epididymal (EAT) adipose

19. Incorporation of dietary trans monounsaturated fatty acids into tissues of Walker 256 tumor-bearing rats
The correlation between dietary trans fatty acids and neoplasia was examined in the present study. Walker 256 tumor-bearing and control rats were fed a trans monounsaturated fatty acid (MUFA)-rich diet for 8 weeks and the incorporation of trans fatty acids by tumor tissue was examined. Also, the effect of tumor growth on trans fatty acid composition of plasm

20. Regulation of Sterol Content in Membranes by Subcellular Compartmentation of Steryl-Esters Accumulating in a Sterol-Overproducing Tobacco Mutant.
The study of sterol overproduction in tissues of LAB 1-4 mutant tobacco (Nicotiana tabacum L. cv Xanthi) (P. Maillot-Vernier, H. Schaller, P. Benveniste, G. Belliard [1989] Biochem Biophys Res Commun 165: 125-130) over several generations showed that the overproduction phenotype is stable in calli, with a 10-fold stimulation of sterol content when compared w

21. Quantification of anandamide content in animal cells and tissues: the normalization makes the difference
Anandamide (N-arachidonoylethanolamine, AEA) is an endogenous lipid that binds to cannabinoid receptors in the central nervous system and in peripheral cells. Quantitative analysis of AEA is generally based on the normalization to the fresh weight of the samples. Here, we show that the normalization procedure of AEA content is such a critical factor, that it

22. Shotgun lipidomics of neutral lipids as an enabling technology for elucidation of lipid-related diseases
Neutral lipids fulfill multiple specialized roles in cellular function. These roles include energy storage and utilization, the synthesis of complex lipids in cellular membranes, lipid second messengers for cellular signaling, and the modulation of membrane molecular dynamics. We have developed a novel mass spectrometric technology, now termed shotgun lipido

23. Predictable "individual differences" in uptake and excretion of gases and lipid soluble vapours simulation study.
A five-compartment pharmacokinetic model with two excretory pathways, exhalation and metabolism, based on first order kinetics is used to outline the effect of body build, pulmonary ventilation, and lipid content in blood on uptake, distribution, and clearance of low solubility gases and lipid soluble vapours during and after exposure. The model shows the ex

24. Disruption of Glycosylphosphatidylinositol-Anchored Lipid Transfer Protein Gene Altered Cuticular Lipid Composition, Increased Plastoglobules, and Enhanced Susceptibility to Infection by the Fungal Pathogen Alternaria brassicicola1[W]
All aerial parts of vascular plants are covered with cuticular waxes, which are synthesized by extensive export of intracellular lipids from epidermal cells to the surface. Although it has been suggested that plant lipid transfer proteins (LTPs) are involved in cuticular lipid transport, the in planta evidence is still not clear. In this study, a glycosylpho
