Ação farmacológica de Syzygium cumini (L.) skeels

Natural products have received new interest recently, maybe in men's attempt to turn into the nature for the prevention and the relief of diseases, mainly because of those untreated by the traditional medicine. Syzygium cumini (L.) Skeels, popularly known as 'jambolão, is a well-known plant by several pharmacological actions so much in the popular use as in the scientific literature. In this search antidiabetic, anti-diarrhoeal, anti-inflammatory, antioxidant and antimicrobial activities of 'jambolão' were described, among other actions.

Inibidores da HIV-integrase: Potencial abordagem farmacológica para tratamento da AIDS

AIDS has the HIV as its etiological agent. Researches has been done to find new pharmacological agents to be used in therapy, because of problems of resistance and side effects. The HIV-integrase inhibitors are some of those new agents that are being studied. This updating focusses on the fundamental information about HIV and HIV-integrase and the main methods being used to develop these new drugs, with examples for each case.

Planejamento, síntese e avaliação farmacológica de compostos híbridos potencialmente ativos para o tratamento da anemia falciforme

Sickle cell disease (SCD) is a hereditary hemolytic anemia caused by the inheritance of one S hemoglobin gene from each ancestor. Patients with SCD present increased circulating levels of cytokines, including TNF-alpha (TNF-α). Hydroxyurea (HU) is the available therapeutically strategy for treatment; it acts as a source of nitric oxide and benefits patients by increasing the levels of fetal hemoglobin (HbF). Thus, within one research line that aims at finding new drugs, a series of compounds with TNF-α inhibition and nitric oxide donation properties have been synthesized in order to explore possible synergism of actions beneficial in the treatment of the disease. Six compounds were synthesized: five derivatives of organic nitrates and one of sulfonamide. The compounds, (1,3-dioxo-1,3-dihydro-2Hisoindol-2-yl) methyl nitrate (compound I); (1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) ethyl nitrate (compound II); 3-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) benzyl nitrate (compound III);4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N-hydroxybenzenesulfonamide (compound IV); 4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) benzyl nitrate (compound V) and 2-[4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) phenyl]ethyl nitrate (compound VI), were synthesized using linear synthetic methodology, with excellent overall yields. All compounds showed anti-inflammatory and analgesic effects with a reduction in 43%-65% of ear edema in mice and a reduction of 25%-42% of writhing induced by acetic acid. All compounds showed comparable reductions in the leukocyte infiltration capacity and ability to generate nitric oxide. The aryl compounds (III, IV and V) presented less mutagenic activity compared to compounds I, II and VI according to the salmonella mutagenicity assay (Ames test). Compounds IV and VI showed activity in K562 culture cells, with increases in gamma globin gene expression to levels higher than with hydroxyurea suggesting a potential to increase fetal hemoglobin. This data set characterizes new potentially useful drug candidates for the treatment of symptoms of sickle cell anemia.

Restauração florestal visando à conservação de recursos hídricos por meio da combinação linear ponderada

This study evaluated using of Multicriteria Evaluation in a GIS, specifically by Weighted Linear Combination Method for generation of map of priority areas for forest restoration in the initial part of River Pardo Basin, SP, in order to water resources conservation. Aiming to define criteria and restrictions it was used Participatory Techniques, and the following factors had been selected: proximity of the hydrographic network, proximity of forest cover, slope and erodibility of soil. To calculate the weight to each factor it was used the decision-making process, known as Analytic Hierarchy Analysis, this method consists of a paired comparison of factors to determine the relative importance of each. According to Weighted Linear Combination, the very high priority areas have a more limited spatial distribution, with an apparent concentration around the water bodies, outlining a buffer to the river system. The proximity factor of the hydrographic network, and enables the connection forestry, contributed, along with the factor of proximity to forest cover, so there would be the definition of most of the areas with the highest priority in the basin, which concentrate the largest areas of forest and native riparian areas along the hydrographic.

Influência da combinação de dados GPS e GLONASS no georreferenciamento de imóveis rurais

The land question has been a widely discussed topic in Brazil, regarding land tenure. Law No. 10.267/01 was a major breakthrough for the agrarian issue. Since then on all rural properties must be georeferenced to the Brazilian Geodetic System (BGS). Therefore, satellite positioning and conventional methods are extensively used. Changes have been occurring in satellite positioning systems due to the addition of new signals in GPS (Global System Positioning), restructuring of GLONASS (Global Orbiting Navigation Satellite System), and the new systems like Galileo and Compass as well. To evaluate the effects of combining GPS and GLONASS data, several batches of processings were performed on different configurations. The data processing was performed to determine the coordinates of points of basic support and those materializing the neighborhood of the rural properties. As a result, it was found that the use of accurate ephemeris in transporting coordinates to support points has no significant influence, since transportation with broadcast ephemeris also meets the accuracy requirements for the Standard Technique for Georreferencing Rural Properties. On the other hand, when GPS and GLONASS data were used, such combination provides the best results. In the case of neighboring points, the use of GPS and GLONASS data is also recommended because such data meet the precision requirement and showed better results than those from where data were processed separately.
