2. Anti-inflammatory activity and chemical analysis of extracts from Trifolium riograndense
Abstract Aiming to investigate new therapeutic agents with fewer side effects, the number of studies about natural products has increased. Phenolic compounds comprise a well-studied class of abundant plant-derived compounds, whose anti-inflammatory activity has been described. Isoflavones are phenolic compounds that occur mainly in the Leguminosae family, an

3. Synthetic Analogue of the Natural Product Piperlongumine as a Potent Inhibitor of Breast Cancer Cell Line Migration
Piperlongumine is a natural amide alkaloid isolated from several species of Piper and is described in the literature as selectively cytotoxic to several cancer cell lines. Inhibiting cell migration has gained considerable interest as an approach for discovering antimetastatic agents because this process is fundamental to metastasis. Piperlongumine, selected

4. Propofol inhibits invasion and growth of ovarian cancer cells via regulating miR-9/NF-κB signal
Propofol is one of the most commonly used intravenous anesthetic agents during cancer resection surgery. A previous study has found that propofol can inhibit invasion and induce apoptosis of ovarian cancer cells. However, the underlying mechanisms are not known. miR-9 has been reported to be little expressed in ovarian cancer cells, which has been related to

6. Anti-inflammatory activity and acute toxicity studies of hydroalcoholic extract of Herissantia tiubae
ABSTRACT Hydroalcoholic extract of aerial parts of Herissantia tiubae (K. Schum.) Brizicky, Malvaceae, was evaluated in experimental models of inflammation and toxicity. For toxicity assays, male and female Swiss mice were orally treated with hydroalcoholic extract of H. tiubae (2000 mg/kg) and analyzed by consumption of water and food, body weight, mortalit

8. Estudo das populações de flebotomíneos transmissores de Leishmania no Panamá / Study of sand fly population transmitter of Leishmania in Panam
The sand flies are insects of the order Diptera (nematocera), family Psychodidae, subfamily Phlebotominae that are recognized as important disease vectors. They are known to be vectors of arbovirus belonging to the family Reoviridae, Bunyaviridae and Rhabdoviridae as well as vectors of bacteria of family Bartonellacea. However, sand flies gained more epidemi

9. Paradoxical effect of a pequi oil-rich diet on the development of atherosclerosis: balance between antioxidant and hyperlipidemic properties
Pequi is the fruit of Caryocar brasiliense and its oil has a high concentration of monounsaturated and saturated fatty acids, which are anti- and pro-atherogenic agents, respectively, and of carotenoids, which give it antioxidant properties. Our objective was to study the effect of the intake of a cholesterol-rich diet supplemented with pequi oil, compared t

12. Interação trófica entre Podisus nigrispinus e Supputius cincticeps (Heteroptera: Pentatomidae) / Trophic interaction between Podisus nigrispinus and Supputius cincticeps (Heteroptera: Pentatomidae)
Prey may be more or less consumed by control biologic agents and presents three kinds of interspecific interactions, (1) synergism, increase of mortality of prey comparing to each natural enemy independently, when the foraging of one species facilitates the capture of pest by another natural enemies. (2) Total mortality of the pest to natural enemies equals
