Dispersão de sementes de Vismia cayennensis (Jacq.) Pers. (Guttiferae) por morcegos na região de Manaus, Amazonas

We studied the feeding behavior of bats and their role in the seed dispersal of Vismia cayennensis in Manaus region, Amazonas State, northern Brazil. The characteristics of the plant and its fruits fit the chiropterocory syndrome. Five species of phyllostomid bats fed on Vismia fruits: Sturnira lilium, Sturnira tildae, Artibeus concolor, Carollia perspicillata and Rhinophylla pumilio. Apparently there is a relationship between flock foraging behavior and fruit availability in early night. The feeding behavior was similar for all bat species, varying with the presentation mode of the fruits. Seed germination tests and the distributional patterns of the plants indicate that bats are the dispersers of V. cayennensis.

Determination Of The Phenolic Composition From Brazilian Tropical Fruits By Uhplc-ms/ms.

Although Brazil is the third largest fruit producer in the world, several specimens consumed are not well studied from the chemical viewpoint, especially for quantitative analysis. For this reason and the crescent employment of mass spectrometry (MS) techniques in food science we selected twenty-two phenolic compounds with important biological activities and developed an ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method using electrospray (ESI) in negative ion mode aiming their quantification in largely consumed Brazilian fruits (açaí-do-Amazonas, acerola, cashew apple, camu-camu, pineapple and taperebá). Multiple reaction monitoring (MRM) was applied and the selection of proper product ions for each transition assured high selectivity. Linearity (0.99580%), precision (CV<20%) and extraction recovery rate (>80%) were satisfactory and showed that the method provides an efficient protocol to analyze phenolic compounds in fruit pulp extracts.

Reproductive biology of Davilla kunthii A. St-Hil. (Dilleniaceae) in Central Amazonia

This survey aimed at describing the interactions of floral visitors and Davilla kunthii A. St.-Hil. as well as characteristics of its reproductive biology in Itacoatiara, state of Amazonas, Brazil. Tests of the breeding system were performed. The guild of visitors was described according to richness, abundance, relative frequency and constancy. The breeding system tests indicated that D. kunthii is self-compatible. The pollination system was characterized as generalist, with 39 visitor species, from three different orders. Bees were the main group of pollinators, thus some behavioural aspects were described. Th e period of highest foraging activity was between 7 and 10 am. Some species presented agonistic and monopolistic behaviour. Given the behaviour and destructive potential, the Curculionidae seem to have a greater impact as seed predators than pollinators.

Machado de assis's epilepsy

Machado de Assis (1839-1908) is considered the most important Brazilian writer and a great universal literary figure. Little is know about his medical, personal and family history. He hid his «disease» as much as possible. Machado referred to «strange things» having happened to him in his childhood. He described seizures as «nervous phenomena», «absenses», «my illness». Laet observed a seizure and described it as: «... when Machado approached us and spoke to me in disconnected words. I looked at him in surprise and found his features altered. Knowing that from time to time he had nervous problems,... and only permitted Machado take the Laranjeiras Street car, when I saw that he was completely well». A photographically documented seizure is shown. Alencar wrote, «The preoccupation with health was frequent: either he was having the consequences of a fit or was foreboding one». It is clear that Machado presented localized symptomatic epilepsy with complex partial seizures secondarily generalized of unknown etiology. The seizures which began in infancy or childhood had remission in adolescence and then recurred in his thirties and became more frequent in his later years. His depression got markedly worse with age. In our opinion, the greatest consequence of Machado's epilepsy, was his psychological suffering due to the prejudice of the times. Despite this Machado showed all his genius, which is still actual and universal.
