O2 and water permeability tests were performed, the total and individual phenolic compounds content were measured, and the films’ antioxidant activities were determined. The films’ ability to delay lipid oxidation was tested in two model foods: almonds, packaged with LDPE/4LE, PLA/4LE and PLA/6LE for a maximum period of 60 days at 40 °C (accelerated assay); and beef meat, packaged with the PLA/6LE for a maximum period of 11 days at 4 °C. The LE improved the WVP in all of the active films by 33%, 20% and 60% for the LDPE/4LE, PLA/4LE and PLA/6LE films, respectively. At the end of 10 days, the migration of phenolic compounds through the PLA films was measured to be 142.27 and 114.9 μg/dm2 for the PLA/4LE and PLA/6LE films, respectively, and was significantly higher than phenolic compounds migration measured for the LDPE/4LE (15.97 μg/dm2). Naringenin, apigenin, ferulic acid, eriocitrin, hesperidin and 4-hydroxybenzoic acid were the main identified compounds in the PLA, but only 4-hydroxybenzoic acid, naringenin and p-coumaric acid were identified in the LDPE films. Regarding the films’ ability to delay lipid oxidation, LDPE/4LE presented the best results, showing a capacity to delay lipid oxidation in almonds for 30 days. When applied to raw beef meat, the PLA/6LE packaging was able to significantly inhibit lipid oxidation for 6 days, and successfully inhibited total microorganisms’ growth until the 8th day of storage.publishersversionpublishe

Encapsulation into Stealth Liposomes Enhances the Antitumor Action of Recombinant Cratylia mollis Lectin Expressed in Escherichia coli

This study evaluated the in vivo antitumor potential of new recombinant lectin from seeds of Cratylia mollis (rCramoll) expressed in Escherichia coli, free or encapsulated in stealth liposomes, using mice transplanted with sarcoma 180. rCramoll-loaded stealth liposomes (rCramoll-lipo) were formulated by hydration of the lipid film followed by cycles of freezing and thawing, and about 60% of rCramoll was encapsulated. This novel preparation showed particle size, polydispersity index, and pH suitable for the evaluation of antitumor activity in vivo. Tumor growth inhibition rates were 68% for rCramoll and 80% for rCramoll-lipo. Histopathological analysis of the experimental groups showed that both free and encapsulated lectin caused no changes in the kidneys of animals. Hematological analysis revealed that treatment with rCramoll-lipo significantly increased leukocyte concentration when compared with the untreated and pCramoll group. In conclusion, the encapsulation of rCramoll in stealth liposomes improves its antitumor activity without substantial toxicity; this approach was more successful than the previous results reported for pCramoll loaded into conventional liposomes. At this point, a crucial difference between the antitumor action of free and encapsulated rCramoll was found along with their effects on immune cells. Further investigations are required to elucidate the mechanism(s) of the antitumor effect induced by rCramoll

Response of nitrate transporters and PM H + -ATPase expression to nitrogen flush on two upland rice varieties contrasting in nitrate uptake kinetics

These authors contributed equally to this work. Abstract The aim of this study was to evaluate the behavior of high-affinity nitrate (NO 3 -) transporters and plasma membrane H + -ATPase isoforms in rice varieties, contrasting in NO 3 -uptake kinetics parameters. Two varieties of rice were studied: cv. IAC-47 (improved for high N input) and cv. Piauí (a local landrace variety cultivated for low input farmers). We evaluated the expression of two PM H + -ATPase isoforms (OsA2 and OsA7), two NO 3 -transporters (OsNRT2.1 and OsNRT2.2), and OsNAR2.1, the rice regulatory genes for nitrate transport. The results showed that the Piauí variety has higher expression of OsNRT2.1-2.2, OsNAR2.1 and OsA2 and 7, compared to IAC-47 variety, mainly after 24h under low N condition. After 24h of 0.2 mM NO 3 --N resupply, the Piauí variety showed a net nitrate uptake and PM-H + -ATPase activity, 71% and 47% higher than IAC-47, respectively. This behavior of Piauí variety may be a strategy for better harnessing of available N that occurs in the tropical environment in a short period of time, after the onset of the rainy season. Changes in the expression levels of OsNRT2.1-2.2/OsNAR2.1 and OsA2 and 7 occur synchronously over time. Our results suggest the synchronized behavior of high affinity nitrate transporters and PM-H + -ATPases under N flush conditions

Avaliação da inflamabilidade de seis espécies nativas na região sul do Tocantins

The woody vegetation of the Cerrado presents adaptive properties to the fire. The fires during the dry season may cause significant changes in the structure and floristic composition of the vegetation. This study aimed to evaluate the flammability of six native species of a Cerrado fragment located in southern Tocantins. Samples composed of fine materials of the selected species were collected, with a diameter of less than 7 mm, excluding young leaves and apical buds. For each species, 50 repetitions were performed, being analyzed: ignition frequency, ignition time, combustion duration, combustion index, and the determination of flammability value. Among the evaluated species, Curatella americana L., Clethra scabra Pers. and Anacardium occidentale L. Obtained significant values with emphasis on Clethra scabra Pers. Which obtained the highest mean values of the flammability variables. We also observed that most species had a combustion index classified as very high (CI = 4 and CI = 5). With this study we can conclude that most species are flammable, and Clethra scabra Pers. Was the species that presented the best result of the flammability variables being classified as highly flammable. On the other hand, Macrolobium limbatum Spruce ex Benth. var. limbatum and Ziziphus Cinnamomum Triana & Planch. Were the species that obtained the lowest results being classified as weakly flammable.A vegetação lenhosa do Cerrado apresenta propriedades adaptativas ao fogo.
