13. In vitro and in vivo studies of pirarubicin-loaded SWNT for the treatment of bladder cancer
Intravesical chemotherapy is an important part of the treatment for superficial bladder cancer. However, the response to it is limited and its side effects are extensive. Functional single-walled carbon nanotubes (SWNT) have shown promise for tumor-targeted accumulation and low toxicity. In the present study, we performed in vivo and in vitro investigations

14. Growth, fatty acid profile in major lipid classes and lipid fluidity of Aurantiochytrium mangrovei Sk-02 as a function of growth temperature
Aurantiochytrium mangrovei Sk-02 was grown in a medium containing glucose (40 g/l), yeast extract (10 g/L) and sea salts (15 g/L) at temperatures ranging from 12 to 35°C. The fastest growth (µmax= 0.15 h-1) and highest fatty acid content of 415 mg/g-dry cell weight were found in the cells grown at 30°C. However, the cells grown at 12°C showed the highest

15. Cholesterol and phospholipid levels in goat meat as affected by dietary calcium.
O objetivo deste estudo foi determinar os conteudos de colesterol e fosfolipidios em carne de caprinos alimentados com dietas contendo suplementos de calcio. As analises foram feitas na carne de nove animais machos, castrados, sem raca definida, com 17 a 23 meses de idade e peso medio de 22,5kg. Os animais foram criados por 28 semanas em pastagem nativa, rec

17. Dispersões lipídicas de dimiristoil fosfatidilglicerol: um estudo termo-estrutural / Lipid dispersions of dymiristoyl phosphatidylglycerol: a thermo-structural study
Dispersions of the saturated anionic phospholipid dimyristoyl phosphatidyl glycerol (DMPG) have been extensively studied regarding their peculiar thermo-structural behavior. At low ionic strength, the gel-fluid transition is spread along nearly 17 ºC, displaying several thermal events in the calorimetric profile, quite different from the single sharp peak a

18. Desenvolvimento e farmacocinética de antimônio encapsulado em lipossomas de fosfatidilserina utilizando radioisótopos em leishmaniose experimental / Development and pharmacokinetic of antimony encapsulated in liposomes of phosphatidylserine using radioisotopes in experimental leishmaniasis
Leishmaniases are a complex of parasitic diseases caused by intramacrophage protozoa of the genus Leishmania, and is fatal if left untreated. Pentavalent antimonials, though toxic and their mechanism of action being unclear, remain the first-line drugs for treatment. Effective therapy could be achieved by delivering antileishmanial drugs to these sites of in

19. Proteoliposomes as matrix vesicles' biomimetics to study the initiation of skeletal mineralization
During the process of endochondral bone formation, chondrocytes and osteoblasts mineralize their extracellular matrix by promoting the formation of hydroxyapatite (HA) seed crystals in the sheltered interior of membrane-limited matrix vesicles (MVs). Ion transporters control the availability of phosphate and calcium needed for HA deposition. The lipidic micr

20. Effect of FSH and insulin on lipogenesis in cultures of Sertoli cells from immature rats
Follicle-stimulating hormone (FSH) and insulin regulate glycide metabolism in Sertoli cells, thus stimulating lactate production. These stimulatory effects of FSH and insulin do not require protein synthesis, suggesting a modulation of enzyme activity and/or regulation of glucose transport. The present investigation was performed to characterize the hormonal

21. Caracterização por espalhamento de luz de dispersões aquosas de agregados lipídicos aniônicos / Structural characterization of aqueous dispersions of the anionic phospholipid DMPG by light scattering
Neste trabalho caracterizamos dispersões aquosas de vesículas lipídicas por espalhamento de luz. Utilizamos os diferentes métodos da técnica: espalhamento de luz estático (SLS) e espalhamento de luz dinâmico (DLS) no estudo desses sistemas. No SLS a intensidade da luz espalhada foi coletada em vários ângulos de espalhamento para diferentes concentra

22. Estudo morfológico e histoquímico do intestino médio de larvas de Anticarsia gemmatalis (Hübner 1818) (Lepidoptera: noctuidae) suscetíveis e resistentes ao AgMNPV alimentadas com genótipos de plantas resistentes a insetos
The velvetbean caterpillar, Anticarsia gemmatalis (Lepidoptera: Noctuidae) is a pest of soybean. To control this insect have been employed as technical biological control by nucleopolyedrovirus (AgMNPV) and the resistance of plants with cultivars that have a complex of chemicals (flavonoids), wich can make them toxic to insects. The midgut is considered the

23. Atividade antioxidante e hepatoprotetora de plantas brasileiras, contendo compostos fenólicos.
Plants from Brazilian flora were chosen and studied for their in vitro and in vivo antioxidant and in vivo hepatoprotetive activity, especially in relation to phenolic compounds which have several health benefits. These plants include Phyllanthus niruri, Solanum fastigiatum, Solidago microglossa and Baccharis trimera. The aqueous extracts of leaves showed in

24. Structural properties of lipid reconstructs and lipid composition of normotensive and hypertensive rat vascular smooth muscle cell membranes
Multiple cell membrane alterations have been reported to be the cause of various forms of hypertension. The present study focuses on the lipid portion of the membranes, characterizing the microviscosity of membranes reconstituted with lipids extracted from the aorta and mesenteric arteries of spontaneously hypertensive (SHR) and normotensive control rat stra
