Sobre um retrato vivo de Kleist
Pompeu, Douglas;
Pandaemonium Germanicum , 2011, DOI: 10.1590/S1982-88372011000200004
Abstract: the purpose of this paper is to present a discussion of some of the main characteristics of robert walser's short story kleist in thun, in an attempt to reflect on how the literary text can establish a dialogue with tradition. this is achieved by the fictionalisation of the character of a real author, more specifically by the narrative genre often used by walser: the portrayal.

Abstract: in order to evaluate the effect of two amazonian species on chronic diseases linked with the oxidative processes, we performed antioxidant capacity analyses (oxygen radical absorbance capacity - orac and folin-ciocalteu - pt assays) and pharmacological effects in vitro (antiproliferative effect) and in vivo (antinociceptive, antiinflammatory, antiulcerogenic effects) for ethanolic extracts (65:35; v/v; ethanol:water) from byrsonima crassifolia (bc) and inga edulis (ie) leaves. both bc and ie extracts showed high orac values (1,422 and 694 mmol of trolox equivalent/g of dry leaf, respectively) and high pt contents (35.93 and 24.50 mg gallic acid equivalent g-1 dry leaf, respectively). the orac values had no correlation with pt, suggesting the presence of other chemical groups in the antioxidant activity value. the two extracts did not present significant antiproliferative activity on nine lines of human tumor cells, and cytotoxic effect was detected only at the highest concentration. the antinociceptive effect was investigated using the hot plate test, and ie extract presented a longer latency (p < 0.05) 30 and 60 min after oral administration. the antiin?ammatory activity was only observed at the highest concentration, suggesting that the antinociceptive effect observed was not due to the antiinflammatory effect. the extracts of both species reduced the ulcerative lesions produced by ethanol up to 84% (p < 0.05), suggesting a relation with the antioxidant capacity. more studies are necessary to elucidate the mechanisms of action involved on antiulcerative effects.
Effects of caffeine on the electrophysiological, cognitive and motor responses of the central nervous system
Deslandes, A.C.;Veiga, H.;Cagy, M.;Piedade, R.;Pompeu, F.;Ribeiro, P.;
Brazilian Journal of Medical and Biological Research , 2005, DOI: 10.1590/S0100-879X2005000700011
Abstract: caffeine is the most consumed psychoactive substance in the world. the effects of caffeine have been studied using cognitive and motor measures, quantitative electroencephalography (qeeg) and event-related potentials. however, these methods are not usually employed in combination, a fact that impairs the interpretation of the results. the objective of the present study was to analyze changes in electrophysiological, cognitive and motor variables with the ingestion of caffeine, and to relate central to peripheral responses. for this purpose we recorded event-related potentials and eyes-closed, resting eeg, applied the stroop test, and measured reaction time. fifteen volunteers took caffeine (400 mg) or placebo in a randomized, crossover, double-blind design. a significant reduction of alpha absolute power over the entire scalp and of p300 latency at the fz electrode were observed after caffeine ingestion. these results are consistent with a stimulatory effect of caffeine, although there was no change in the attention (stroop) test or in reaction time. the qeeg seems to be the most sensitive index of the changes produced by caffeine in the central nervous system since it proved to be capable of detecting changes that were not evident in the tests of cognitive or motor performance.
Ocular metastasis as first presentation of renal cell carcinoma: report of 2 cases
Pompeu, Antonio Carlos Lima;Arap, Sami;Silva, Matheus Neves R.;Monteiro, Daniel S.;
Clinics , 2005, DOI: 10.1590/S1807-59322005000100014
Abstract: authors report the cases of 2 patients who had an ocular lesion as the first sign leading to diagnosis of renal cell carcinoma, an uncommon presentation of this neoplasm. the first patient was a 59-year-old man presented with a mass in the right eye. the histological and immunohistochemical profile of the biopsy showed a probable renal cell carcinoma. a ct scan showed a solid mass in the left kidney. the patient underwent radical nephrectomy and excision of the ocular lesion and had an uneventful evolution. the second patient was a 72-year-old man presenting with an ulcerated lesion on the right inferior tarsal conjunctiva. an excisional biopsy of the lesion showed histological and immunohistochemical patterns of a clear cell carcinoma. abdominal tomography disclosed a right peripheral renal tumor. a right radical nephrectomy was performed. renal cell carcinoma may present atypically with metastases to quite uncommon organs. nephrectomy may be of value in selected cases; the ocular metastases are usually excised for aesthetic and functional reasons.

CERNE , 2012,
Abstract: This research evaluated the quality of forest harvest using chainsaw, in farms in the south of Espirito Santo state, Brazil, considering aspects of quality and loss of wood left in the strains. A total of 250 m2 plots were launched to collect data of forest cut with chainsaw, for evaluating the quality of the cut related mto: presence of skewers; crack damage; strains burst range nonstandard; strains without the notch directional, and the remaining height of the strain, in order to measure the loss of wood held in the strains. The main results were: the spike was present in 21.9% of the strains, the cracks in 17.2% of the strains, non-standard strains in 44.6% of them and unnotched directional strains in 34.5% of the evaluations. To check the influence of the realization of the directional notch on the height of the strains t-test, at 5% probability, has shown that there is an increased contribution to height of the strains, where the cut was made without the directional notch. The amount of wood held in the strains above the recommended maximum was, on average, 2.43 m3.ha-1, representing a loss of R$ 172.53 ha-1. It was verified that the loss of timber remaining in eucalyptus strains was higher in places where, for the logging, there was not done the directional notch. The items evaluated showed uneven quality, indicating the need to improve cutting with chainsaw.
