Inosine, a naturally occurring purine formed from the breakdown of adenosine, is associated with immunoregulatory effects. Evidence shows that inosine modulates lung inflammation and regulates cytokine generation. However, its role in controlling allergen-induced lung inflammation has yet to be identified. In this study, we aimed to investigate the role of(More)
Nucleation is a natural process in which trees scattered in the landscape promote changes in the surrounding environment, which increases the probability of seedling and sapling colonization in a nucleus area. This study aimed to describe forest species community under the crown of Bowdichia virgilioides (Fabaceae) in cerrado sensu stricto, testing two(More)
A qualitative characterization of the main phenolic compounds from ethanol extract of Hymenaea martiana was carried out by high performance liquid chromatography with diode array detection (HPLC-DAD). The total phenolics content of the plant extracts was determined by the Folin-Ciocalteu method. Total flavonoid content also was measured. Antioxidant(More)
Studies report the forest expansion process toward open savanna areas; however, most of them were conducted by means of satellite images and aerial photographs. This study has investigated the forest expansion process through community dynamics over 15 years of permanent plots monitoring. The study was conducted at a forest continuum of three distinct(More)
BACKGROUND Popularly known as "jatobá," Hymenaea martiana Hayne is a medicinal plant widely used in the Brazilian Northeast for the treatment of various diseases. OBJECTIVE The aim of this study was to evaluate the influence of different extractive methods in the production of phenolic compounds from different parts of H. martiana. MATERIALS AND METHODS(More)
Plants in a seasonal environment that become close to the artificial lake after dams construction may have enhanced growth or die due to the new conditions. Changes in mortality or growth rates lead to changes in community diversity, and we do not know if the community functions will change; our main hypothesis was that a few years after impoundment,(More)
Lonchocarpus araripensis Benth. is largely distributed in the northeast region of Brazil. It is popularly known as 'sucupira'. Recent studies have shown that some species of Lonchocarpus have interesting pharmacological activities. In this study, we evaluated the antinociceptive effect of a flavone isolated from L. araripensis. The chemical examination(More)
The bidirectional relationship between the nervous system and the immune system is relevant for homeostatic organism maintenance. Studies from our laboratory showed that 14days of cohabitation with a sick partner (injected with Ehrlich tumor cells-TAE) produced behavioral, neurochemical, endocrinological and immunological changes. This study analyzes the(More)
