Abstract: in order to detect rotavirus and adenovirus 557 feces samples from hospitalized children (0-5 years of age) were analysed from june 1987 to july 1990 in goiania-city.two hundred and ninety one samples were from children with diarrhoea and 266 were from children without diarrhoea. amongst this later group, 64 samples were from children from the nursery. two hundred and sixty one out of 557 samples were analysed by immunoelectron microscopy (iem), polyacrylamide gel electrophoresis (sds-page) and enzymatic immunoassay for rotavirus and adenovirus (eiara) whereas the rest (296 samples) were analysed by sds-page and eiara. positivity of rotavirus and adenovirus was 17.2% and 2.1% respectively. concerning rotavirus and adenovirus there was 29.2% and 2.4% positivity within the group with diarrhoea and 4.1% and 1.5% positivity amongst children without diarrhoea (p<0.05). rotavirus were more prevalent amongst children which age ranged from 1 to 11 months of age. no newborn child from the nursery was positive for rotavirus. adenovirus were detected amongst children from 1 to 3 years of age. rotavirus circulation peak occurred between may and august (p<0.05) and no positive case was detected from december to february. two hundred out of 291 diarrheic samples were also studied concerning bacteria and pathogenic parasites and equal percentages (17.0%) were found for both rotavirus and pathogenic bacteria. eighty nine samples of rotavirus were detected by sds-page and 86 of these (96.6%) belonged to the subgroup ii with 13 different electrophoretic patterns. predominance of a given eletropherotic profile was observed in each year of the study.
The emergence of Klebsiella pneumoniae endogenous endophthalmitis in the USA: basic and clinical advances

Abstract: Endogenous endophthalmitis (EE) is a relatively uncommon but severe infection that comprises 2% to 15% of all cases of endophthalmitis [1-3]. It is commonly associated with underlying immunosuppression including diabetes mellitus, cardiac disease, renal insufficiency and malignancy. While a number of organisms have been implicated in EE, Klebsiella pneumoniae has been recognized as an increasingly prevalent cause of EE in the Asian population [1,2,4-12]. In addition to numerous case series from Asia, a growing body of basic scientific research has begun to elucidate the pathophysiology of this particular infection. In this case series and review, we report two cases of systemic Klebsiella infection that resulted in EE within the USA. We also discuss recent literature that is starting to shed light on the epidemiology and pathophysiology of this condition.The clinical experience with K. pneumoniae endogenous endophthalmitis (KPEE) is varied, and comparison of the numerous retrospective studies is difficult due to differences in the methods and reporting criteria [1]. Nevertheless, several large retrospective studies report a surprisingly high number of cases of KPEE among patients with EE (Table?1). Wong et al. reported a series of 27 patients with bacterial EE from Singapore over a 4-year period [6]. Sixty percent of cases were secondary to K. pneumoniae, and 48% of these had hepatobiliary sources of infection. Chen et al. reported 74 patients with EE from Taiwan over a 10-year period [5]. Sixty-one percent of cases were secondary to K. pneumoniae, and 53% of these cases had liver abscess. Ang et al. reported 113 patients with EE from Singapore over a 21-year period [9]. Sixty-one patients (54%) and 71 eyes had KPEE. These studies demonstrate that among patients with EE in Asia, the prevalence of KPEE is high (54% to 61%; Table?1). In contrast, Jackson et al. reported a series of 21 eyes in 19 patients with EE from England over a 17-year period, and only one case wa
The Thames Discovery Programme: Public Engagement and Research on London’s Foreshore

Archaeology International , 2012, DOI: 10.5334/ai.1506
Abstract: The Thames Discovery Programme (TDP) – a community archaeology project funded by the Heritage Lottery Fund (from 2008–2011) and now hosted by Museum of London Archaeology – has maintained close links with UCL throughout the lifetime of the project. This continues the association established by our predecessor project, the Thames Archaeological Survey (Milne et al., 1997: 130–146), which was directed by Gustav Milne (from 1995–1999) and encouraged participation by UCL Institute of Archaeology students in foreshore fieldwork and research. This paper summarises initiatives undertaken by the TDP, with the support of UCL’s Public Engagement Unit, and further research by Institute students.

Direitos à floresta e ambientalismo: seringueiros e suas lutas

Revista Brasileira de Ciências Sociais , 2004, DOI: 10.1590/S0102-69092004000200003
Abstract: the amazonian rubber-tappers were invisible in the national scene in the 1970's. they started to organize themselves as an agrarian movement early in the 1980's and in the 1990's they obtained national recognizance, having the first extractive reserves being implemented right after chico mendes's assassination. thus, these peasants of the tropical forest went from invisibility to paradigms of sustainable, participatory development in just two decades. this article narrates this historical episode by studying the trajectories of leaders, as well as the strategies employed by them in order to obtain visibility for the social movement both in national and international scale, connecting their agrarian claims to environmental issues of more general interest.
Guerras culturais e relativismo cultural
Almeida, Mauro W. Barbosa de;
Revista Brasileira de Ciências Sociais , 1999, DOI: 10.1590/S0102-69091999000300001
Abstract: in recent debates known as "the culture wars", sokal and bricmont have challenged what they call "intellectual fraud" perpetrated by social scientists/philosophers/cultural critics who mention science (or make use of scientific argument) in order to support relativistic stances. a paradigmatic example of "intellectual fraud" would be the statement that the number p is "socially constructed". through a discussion of this example, the author proposes an alternative point of view based on what he calls a moderate version of relativism. this version relies on the notion that it is always possible to translate between distinct ontologies, thus guaranteeing intersubjectivity and, consequently, objectivity. finally, he argues against sokal and bricmont's intent of imposing rules for the good usage of metaphors in the human sciences.

Guerras culturais e relativismo cultural
Almeida Mauro W. Barbosa de
Revista Brasileira de Ciências Sociais , 1999,
Abstract: Sokal e Bricmont, em debates recentes conhecidos como as "guerras da cultura", criticaram o que chamaram de "fraude intelectual" promovida por cientistas sociais/filósofos/críticos literários que se referem a temas científicos para defender posi es relativistas. Um exemplo paradigmático de "fraude intelectual" seria a afirma o de que o número p é uma constru o social. A partir da discuss o desse exemplo, defendo um ponto de vista alternativo, baseado no que chamo de vers o moderada do relativismo. Essa vers o repousa sobre a no o de que é sempre possível a tradu o entre ontologias distintas, o que garante a intersubjetividade e, conseqüentemente, a objetividade. Finalmente, argumento contra o intento de Sokal e Bricmont de impor regras ao uso adequado de metáforas no discurso das ciências humanas.

CHARACTERISATION OF ISOELEUTHERINE IN AQUEOUS EXTRACT OF ELEUTHERINE PLICATA HERB, IRIDACEAE, ACTIVE AGAINST ENTAMOEBA HYSTOLITICA/ ENTAMOEBA DISPAR IN VITRO
W. L. R. Barbosa et al.
International Journal of Pharmaceutical Sciences and Research , 2012,
Abstract: Eleutherine plicata Herb., Iridaceae, is an herbaceous Iridaceae, vernacular marupazinho, largely used as tea, in the Amazonian popular phytotherapy, to treat diarrhoea alleged to amoeba infestation. To investigate the form of use of this medicinal plant and its alleged activity, and to perform a phytochemical analysis and an anti-amoebaean assay. Bulbs of the plant were dried, grinded and extracted in boiling water. After concentration the extract (AEEp) was analysed by LC-DAD and tested against trophozoitic forms of three strain of Entamoeba histolytica/Entamoeba dispar. A significant peak in the LC-DAD chromatogram of AEEp can be observed and attributed to isoeleutherine, a naphtoquinone also an antiamoebian activity was detected for this extract. Isoeleutherine would be one of the active substances responsible for the anti-amoebaean activity of Eleutherine plicata Herb., since naphtoquinone show anti-protozoal activity and the substance shows pro-oxidative properties. Noteworthy is the fact that the decoction shows 3.5mg dry residue/mL, 40% higher than the concentration of the extract used in the bioassay (2.5mg/mL). The detected antiamoebian activity for AEEp aligns to the popular attribution of its use and the presence of Isoleutherine can partially explain this observation.
